                            YIELD INFORMATION
        From time to time, the Fund advertises its yield and effective yield.
Both yield figures are based on historical earnings and are not intended to
indicate future performance. It can be expected that these yields will
fluctuate substantially. The yield of the Fund refers to the income generated
by an investment in the Fund over a seven-day period (which period will be
stated in the advertisement). This income is then annualized. That is, the
amount of income generated by the investment during that week is assumed to
be generated each week over a 52-week period and is shown as a percentage of
the investment. The effective yield is calculated similarly, but, when
annualized, the income earned by an investment in the Fund is assumed to be
reinvested. The effective yield will be slightly higher than the yield
because of the compounding effect of this assumed reinvestment. The Fund's
yield and effective yield may reflect absorbed expenses pursuant to any
undertaking that may be in effect. See "Management of the Fund."
        Tax equivalent yield is calculated by determining the pre-tax yield
which, after being taxed at a stated rate, would be equivalent to a stated
yield or effective yield calculated as described above.
        Yield information is useful in reviewing the Fund's performance, but
because yields will fluctuate, such information under certain conditions may
not provide a basis for comparison with domestic bank deposits, other
investments which pay a fixed yield for a stated period of time, or other
investment companies which may use a different method of computing yield.
   

        Comparative performance information may be used from time to time in
advertising or marketing the Fund's shares, including data from Lipper
Analytical Services, Inc., Bank Rate Monitortrademark, N. Palm Beach, Fla.
33408, IBC's Money Fund ReportTM, Morningstar, Inc. and other industry
publications.
    

                           DESCRIPTION OF THE FUND
INVESTMENT OBJECTIVE
        The Fund's investment objective is to provide you with as high a
level of current income exempt from Federal and Massachusetts income taxes as
is consistent with the preservation of capital and the maintenance of
liquidity. To accomplish its investment objective, the Fund invests primarily
in the debt securities of the Massachusetts, its political subdivisions,
authorities and corporations, the interest from which is, in the opinion of
bond counsel to the issuer, exempt from Federal and Commonwealth of
Massachusetts income taxes (collectively, "Massachusetts Municipal
Obligations"). To the extent acceptable Massachusetts Municipal Obligations
are at any time unavailable for investment by the Fund, the Fund will invest
temporarily in other debt securities the interest from which is, in the
opinion of bond counsel to the issuer, exempt from Federal, but not
Massachusetts, income tax. The Fund's investment objective cannot be changed
without approval by the holders of a majority (as defined in the Investment
Company Act of 1940, as amended (the "1940 Act")) of the Fund's outstanding
voting shares. There can be no assurance that the Fund's investment objective
will be achieved. Securities in which the Fund invests may not earn as high a
level of current income as long-term or lower quality securities which
generally have less liquidity, greater market risk and more fluctuation in
market value.
MUNICIPAL OBLIGATIONS
        Debt securities the interest from which is, in the opinion of bond
counsel to the issuer, exempt from Federal income tax ("Municipal
Obligations") generally include debt obligations issued to obtain funds for
various public purposes as well as certain industrial development bonds
issued by or on behalf of public authorities. Municipal Obligations are
classified as general obligation bonds, revenue bonds and notes.

General obligation bonds are secured by the issuer's pledge of its faith,
credit and taxing power for the payment of principal and interest. Revenue
bonds are payable from the revenue derived from a particular facility or class
of facilities or, in some cases, from the proceeds of a special excise or
other specific revenue source, but not from the general taxing power. Tax
exempt industrial development bonds, in most cases, are revenue bonds that do
not carry the pledge of the credit of the issuing municipality, but generally
are guaranteed by the corporate entity on whose behalf they are issued. Notes
are short-term instruments which are obligations of the issuing municipalities
or agencies and are sold in anticipation of a bond sale, collection of taxes
or receipt of other revenues. Municipal Obligations include municipal
lease/purchase agreements which are similar to installment purchase contracts
for property or equipment issued by municipalities. Municipal Obligations
bear fixed, floating or variable rates of interest.
MANAGEMENT POLICIES
        It is a fundamental policy of the Fund that it will invest at least
80% of the value of its net assets (except when maintaining a temporary
defensive position) in Municipal Obligations. Under normal circumstances, at
least 65% of the value of the Fund's net assets will be invested in
Massachusetts Municipal Obligations and the remainder may be invested in
securities that are not Massachusetts  Municipal Obligations and therefore
may be subject to Massachusetts income taxes. See "Investment Considerations
and Risks _ Investing in Massachusetts Municipal Obligations" below, and
"Dividends, Distributions and Taxes." The Fund also may invest in Taxable
Investments of the quality described under "Appendix -- Certain Portfolio
Securities -- Taxable Investments."
   

        The Fund seeks to maintain a net asset value of $1.00 per share for
purchases and redemptions. To do so, the Fund uses the amortized cost method
of valuing its securities pursuant to Rule 2a-7 under the 1940 Act, which
Rule includes various maturity, quality and diversification requirements,
certain of which are summarized as follows. In accordance with Rule 2a-7, the
Fund is required to maintain a dollar-weighted average portfolio maturity of
90 days or less, purchase only instruments having remaining maturities of 13
months or less, and invest only in U.S. dollar denominated securities
determined in accordance with procedures established by the Fund's Board to
present minimal credit risks and which are rated in one of the two highest
rating categories for debt obligations by at least two nationally recognized
statistical rating organizations (or one rating organization if the
instrument was rated by only one such organization) or, if unrated, are of
comparable quality as determined in accordance with procedures established by
the Board. The nationally recognized statistical rating organizations
currently rating instruments of the type the Fund may purchase are Moody's
Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Group ("S&P"),
and Fitch Investors Service, L.P. ("Fitch") and their rating criteria are
described in "Appendix B" to the Statement of Additional Information. For
further information regarding the amortized cost method of valuing
securities, see "Determination of Net Asset Value" in the Statement of
Additional Information. There can be no assurance that the Fund will be able
to maintain a stable net asset value of $1.00 per share.
    

        From time to time, the Fund may invest more than 25% of the value of
its total assets in industrial development bonds which, although issued by
industrial development authorities, may be backed only by the assets and
revenues of the non-governmental users. Interest on Municipal Obligations
(including certain industrial development bonds) which are specified private
activity bonds, as defined in the Internal Revenue Code of 1986, as amended
(the "Code"), issued after August 7, 1986, while exempt from Federal income
tax, is a preference item for the purpose of the alternative minimum tax.
Where a regulated investment company receives such interest, a proportionate
share of any exempt-interest divi-
                                    Page 5

dend paid by the investment company may be treated as such a preference item
to shareholders. The Fund may invest without limitation in such Municipal
Obligations if The Dreyfus Corporation determines that their purchase is
consistent with the Fund's investment objective. See "Investment
Considerations and Risks" below.
INVESTMENT CONSIDERATIONS AND RISKS
GENERAL -- Even though interest-bearing securities are investments which
promise a stable stream of income, the prices of such securities are
inversely affected by changes in interest rates and, therefore, are subject
to the risk of market price fluctuations. The values of fixed-income
securities also may be affected by changes in the credit rating or financial
condition of the issuing entities.
   

INVESTING IN MASSACHUSETTS MUNICIPAL OBLIGATIONS -- Since the Fund is
concentrated in securities issued by Massachusetts or entities within
Massachusetts, an investment in the Fund may involve greater risk than
investments in certain other types of money market funds. You should consider
carefully the special risks inherent in the Fund's investment in
Massachusetts Municipal Obligations. Since 1989, Massachusetts has
experienced growth rates significantly below the national average and an
economic recession in 1990 and 1991 caused negative growth rates in
Massachusetts. Massachusetts' economic difficulties and fiscal problems in
the late 1980s and early 1990s caused several rating agencies to lower their
ratings of Massachusetts Municipal Obligations. A return of persistent
serious financial difficulties could adversely affect the market values and
marketability of, or result in default in payment on, outstanding
Massachusetts Municipal Obligations. Massachusetts' operating losses in
fiscal 1989 and 1990, which totalled $672 million and $1.25 billion,
respectively, were covered primarily through deficit borrowings, and a fiscal
1991 operating loss of $21 million was covered by drawing on the adjusted
1990 fund balance of $258 million. Massachusetts ended fiscal years 1992
through 1996, however, with a positive fiscal balance in its general
operating funds. You should obtain and review a copy of the Statement of
Additional Information which more fully sets forth these and other risk
factors.
    

INVESTING IN MUNICIPAL OBLIGATIONS -- The Fund may invest more than 25% of
the value of its total assets in Municipal Obligations which are related in
such a way that an economic, business or political development or change
affecting one such security also would affect the other securities; for
example, securities the interest upon which is paid from revenues of similar
types of projects. As a result, the Fund may be subject to greater risk as
compared to a fund that does not follow this practice.
        Certain municipal lease/purchase obligations in which the Fund may
invest may contain "non-appropriation" clauses which provide that the
municipality has no obligation to make lease payments in future years unless
money is appropriated for such purpose on a yearly basis. Although
"non-appropriation" lease/purchase obligations are secured by the leased
property, disposition of the leased property in the event of foreclosure
might prove difficult. In evaluating the credit quality of a municipal
lease/purchase obligation that is unrated, The Dreyfus Corporation will
consider, on an ongoing basis, a number of factors including the likelihood
that the issuing municipality will discontinue appropriation funding for
the leased property.
        Certain provisions in the Code relating to the issuance of Municipal
Obligations may reduce the volume of Municipal Obligations qualifying for
Federal tax exemption. One effect of these provisions could be to increase
the cost of the Municipal Obligations available for purchase by the Fund and
thus reduce the available yield. Shareholders should consult their tax
advisers concerning the effect of these provisions on an investment in the
Fund. Proposals that may restrict or eliminate the income tax exemption for
interest on Municipal Obligations may be introduced in the future. If any
such proposal were enacted that would reduce the availability of Municipal
Obligations for investment by the Fund so
                                    Page 6

as to adversely affect Fund shareholders, the Fund would reevaluate its
investment objective and policies and submit possible changes in the Fund's
structure to shareholders for their consideration. If legislation were
enacted that would treat a type of Municipal Obligation as taxable, the
Fund would treat such security as a permissible Taxable Investment within
the applicable limits set forth herein.
NON-DIVERSIFIED STATUS -- The classification of the Fund as a
"non-diversified" investment company means that the proportion of the Fund's
assets that may be invested in the securities of a single issuer is not
limited by the 1940 Act. A "diversified" investment company is required by
the 1940 Act generally, with respect to 75% of its total assets, to invest
not more than 5% of such assets in the securities of a single issuer. Since a
relatively high percentage of the Fund's assets may be invested in the
securities of a limited number of issuers, the Fund's portfolio may be more
sensitive to changes in the market value of a single issuer. However, to meet
Federal tax requirements, at the close of each quarter the Fund may not have
more than 25% of its total assets invested in any one issuer and, with
respect to 50% of total assets, not more than 5% of its total assets invested
in any one issuer. These limitations do not apply to U.S. Government
securities.
SIMULTANEOUS INVESTMENTS -- Investment decisions for the Fund are made
independently from those of other investment companies advised by The Dreyfus
Corporation. If, however, such other investment companies desire to invest
in, or dispose of, the same securities as the Fund, available investments or
opportunities for sales will be allocated equitably to each investment
company. In some cases, this procedure may adversely affect the size of the
position obtained for or disposed of by the Fund or the price paid or
received by the Fund.
                            MANAGEMENT OF THE FUND
   

INVESTMENT ADVISER -- The Dreyfus Corporation, located at 200 Park Avenue,
New York, New York 10166, was formed in 1947 and serves as the Fund's
investment adviser. The Dreyfus Corporation is a wholly-owned subsidiary of
Mellon Bank, N.A., which is a wholly-owned subsidiary of Mellon Bank
Corporation ("Mellon"). As of April 30, 1997, The Dreyfus Corporation managed
or administered approximately $83 billion in assets for approximately 1.7
million investor accounts nationwide.
    

        The Dreyfus Corporation supervises and assists in the overall
management of the Fund's affairs under a Management Agreement with the Fund,
subject to the authority of the Fund's Board in accordance with Massachusetts
law.
   

        Mellon is a publicly owned multibank holding company incorporated
under Pennsylvania law in 1971 and registered under the Federal Bank Holding
Company Act of 1956, as amended. Mellon provides a comprehensive range of
financial products and services in domestic and selected international
markets. Mellon is among the twenty-five largest bank holding companies in
the United States based on total assets. Mellon's principal wholly-owned
subsidiaries are Mellon Bank, N.A., Mellon Bank (DE) National Association,
Mellon Bank (MD), The Boston Company, Inc., AFCO Credit Corporation and a
number of companies known as Mellon Financial Services Corporations. Through
its subsidiaries, including The Dreyfus Corporation, Mellon managed more than
$233 billion in assets as of December 31, 1996, including approximately $86
billion in proprietary mutual fund assets. As of December 31, 1996, Mellon,
through various subsidiaries, provided non-investment services, such as
custodial or administration services, for more than $1.046 trillion in assets
including approximately $57 billion in mutual fund assets.
    
   
        Under the terms of the Management Agreement, the Fund has agreed to
pay The Dreyfus Corporation a monthly fee at the annual rate of .50 of 1% of
the value of the Fund's average daily net assets. For the fiscal year ended
January 31, 1997, the Fund paid The Dreyfus Corporation a monthly management
fee at the effective annual rate of .44 of 1% of the value of the Fund's
average daily net
                                    Page 7

assets pursuant to undertakings by The Dreyfus Corporation. From time to time,
The Dreyfus Corporation may waive receipt of its fees and/or voluntarily
assume certain expenses of the Fund, which would have the effect of lowering
the expense ratio of the Fund and increasing yield to investors. The Fund will
not pay The Dreyfus Corporation at a later time for any amounts it may waive,
nor will the Fund reimburse The Dreyfus Corporation for any amounts it may
assume.
    

          In allocating brokerage transactions, The Dreyfus Corporation seeks
to obtain the best execution of orders at the most favorable net price.
Subject to this determination, The Dreyfus Corporation may consider, among
other things, the receipt of research services and/or the sale of shares of
the Fund or other funds managed, advised or administered by The Dreyfus
Corporation as factors in the selection of broker-dealers to execute
portfolio transactions for the Fund. See "Portfolio Transactions" in the State
ment of Additional Information.
        The Dreyfus Corporation may pay the Fund's distributor for
shareholder services from its own assets, including past profits but not
including the management fee paid by the Fund. The Fund's distributor may use
part or all of such payments to pay securities dealers, banks or other
financial institutions in respect of these services.
   

DISTRIBUTOR -- The Fund's distributor is Premier Mutual Fund Services, Inc.
(the "Distributor"), located at 60 State Street, Boston, Massachusetts 02109.
The Distributor's ultimate parent is Boston Institutional Group, Inc.
    

TRANSFER AND DIVIDEND DISBURSING AGENT AND CUSTODIAN _ Dreyfus Transfer,
Inc., a wholly-owned subsidiary of The Dreyfus Corporation, P.O. Box 9671,
Providence, Rhode Island 02940-9671, is the Fund's Transfer and Dividend
Disbursing Agent (the "Transfer Agent"). The Bank of New York, 90 Washington
Street, New York, New York 10286, is the Fund's Custodian.
                             HOW TO BUY SHARES
        Fund shares are sold without a sales charge. You may be charged a fee
if you effect transactions in Fund shares through a securities dealer, bank
or other financial institution. Share certificates are issued only upon your
written request. No certificates are issued for fractional shares. It is not
recommended that the Fund be used as a vehicle for Keogh, IRA or other
qualified plans. The Fund reserves the right to reject any purchase order.
   

        The minimum initial investment is $2,500, or $1,000 if you are a
client of a securities dealer, bank or other financial institution which
maintains an omnibus account in the Fund and which has made an aggregate
minimum initial purchase for its customers of $2,500. Subsequent investments
must be at least $100. The initial investment must be accompanied by the
Account Application. For full-time or part-time employees of The Dreyfus
Corporation or any of its affiliates or subsidiaries, directors of The Dreyfus
 Corporation, Board members of a fund advised by The Dreyfus Corporation,
including members of the Fund's Board, or the spouse or minor child of any of
the foregoing, the minimum initial investment is $1,000. For full-time or
part-time employees of The Dreyfus Corporation or any of its affiliates or
subsidiaries who elect to have a portion of their pay directly deposited into
their Fund accounts, the minimum initial investment is $50. The Fund reserves
the right to vary further the initial and subsequent investment minimum
requirements at any time. Fund shares also are offered without regard to the
minimum initial investment requirements through Dreyfus-AUTOMATIC Asset
BuilderRegistration Mark, Dreyfus Government Direct Deposit Privilege or
Dreyfus Payroll Savings Plan pursuant to the Dreyfus Step Program described
under "Shareholder Services." These services enable you to make regularly
scheduled investments and may provide you with a convenient way to invest for
long-term financial
                                    Page 8

goals. You should be aware, however, that periodic investment plans do not
guarantee a profit and will not protect an investor against loss in a
declining market.
    

        You may purchase Fund shares by check or wire, or through the Dreyfus
TELETRANSFER Privilege described below. Checks should be made payable to "The
Dreyfus Family of Funds." Payments to open new accounts which are mailed
should be sent to The Dreyfus Family of Funds, P.O. Box 9387, Providence,
Rhode Island 02940-9387, together with your Account Application. For
subsequent investments, your Fund account number should appear on the check
and an investment slip should be enclosed and sent to The Dreyfus Family of
Funds, P.O. Box 105, Newark, New Jersey 07101-0105. Neither initial nor
subsequent investments should be made by third party check. Purchase orders
may be delivered in person only to a Dreyfus Financial Center. THESE ORDERS
WILL BE FORWARDED TO THE FUND AND WILL BE PROCESSED ONLY UPON RECEIPT THEREBY.
For the location of the nearest Dreyfus Financial Center, please call one of
the telephone numbers listed under "General Information."
        Wire payments may be made if your bank account is in a commercial
bank that is a member of the Federal Reserve System or any other bank having
a correspondent bank in New York City. Immediately available funds may be
transmitted by wire to The Bank of New York, DDA #8900119209/Dreyfus
Massachusetts Municipal Money Market Fund, for purchase of Fund shares in
your name. The wire must include your Fund account number (for new accounts,
your Taxpayer Identification Number ("TIN") should be included instead),
account registration and dealer number, if applicable. If your initial
purchase of Fund shares is by wire, please call 1-800-645-6561 after
completing your wire payment to obtain your Fund account number. Please
include your Fund account number on the Account Application and promptly mail
the Account Application to the Fund, as no redemptions will be permitted
until the Account Application is received. You may obtain further information
about remitting funds in this manner from your bank. All payments should be
made in U.S. dollars and, to avoid fees and delays, should be drawn only on
U.S. banks. A charge will be imposed if any check used for investment in your
account does not clear. The Fund makes available to certain large
institutions the ability to issue purchase instructions through compatible
computer facilities.
        Subsequent investments also may be made by electronic transfer of
funds from an account maintained in a bank or other domestic financial
institution that is an Automated Clearing House member. You must direct the
institution to transmit immediately available funds through the Automated
Clearing House to The Bank of New York with instructions to credit your Fund
account. The instructions must specify your Fund account registration and
your Fund account number PRECEDED BY THE DIGITS "1111."
        Fund shares are sold on a continuous basis at the net asset value per
share next determined after an order in proper form and Federal Funds (monies
of member banks within the Federal Reserve System which are held on deposit
at a Federal Reserve Bank) are received by the Transfer Agent. If you do not
remit Federal Funds, your payment must be converted into Federal Funds. This
usually occurs within one business day of receipt of a bank wire or within
two business days of receipt of a check drawn on a member bank of the Federal
Reserve System. Checks drawn on banks which are not members of the Federal
Reserve System may take considerably longer to convert into Federal Funds.
Prior to receipt of Federal Funds, your money will not be invested.
        The Fund's net asset value per share is determined as of 12:00 Noon,
New York time, on each day the New York Stock Exchange is open for business.
Net asset value per share is computed by dividing the value of the Fund's net
assets (i.e., the value of its assets less liabilities) by the total number
of shares outstanding. See "Determination of Net Asset Value" in the
Statement of Additional Information.
                                    Page 9

        If your payments are received in or converted into Federal Funds by
l2:00 Noon, New York time, by the Transfer Agent, you will receive the
dividend declared that day. If your payments are received in or converted
into Federal Funds after 12:00 Noon, New York time, by the Transfer Agent,
you will begin to accrue dividends on the following business day.
        Qualified institutions may telephone orders for purchase of Fund
shares. These orders will become effective at the price determined at 12:00
Noon, New York time, and the shares purchased will receive the dividend on
Fund shares declared on that day if the telephone order is placed by 12:00
Noon, New York time, and Federal Funds are received by 4:00 p.m., New York
time, on that day.
        Federal regulations require that you provide a certified TIN upon
opening or reopening an account. See "Dividends, Distributions and Taxes" and
the Account Application for further information concerning this requirement.
Failure to furnish a certified TIN to the Fund could subject you to a $50
penalty imposed by the Internal Revenue Service (the "IRS").
DREYFUS TELETRANSFER PRIVILEGE -- You may purchase shares (minimum $500,
maximum $150,000) by telephone if you have checked the appropriate box and
supplied the necessary information on the  Account Application or have filed
a Shareholder Services Form with the Transfer Agent. The proceeds will be
transferred between the bank account designated in one of these documents and
your Fund account. Only a bank account maintained in a domestic financial
institution which is an Automated Clearing House member may be so designated.
The Fund may modify or terminate this Privilege at any time or charge a
service fee upon notice to shareholders. No such fee currently is
contemplated.
        If you have selected the Dreyfus TELETRANSFER Privilege, you may
request a Dreyfus TELETRANSFER purchase of shares by calling 1-800-645-6561
or, if you are calling from overseas, call 516-794-5452.
                            SHAREHOLDER SERVICES
FUND EXCHANGES -- You may purchase, in exchange for shares of the Fund,
shares of certain other funds managed or administered by The Dreyfus
Corporation, to the extent such shares are offered for sale in your state of
residence. These funds have different investment objectives which may be of
interest to you. If you desire to use this service, please call
1-800-645-6561 to determine if it is available and whether any conditions are
imposed on its use.
   

        To request an exchange, you must give exchange instructions to the
Transfer Agent in writing or by telephone. Before any exchange, you must
obtain and should review a copy of the current prospectus of the fund into
which the exchange is being made. Prospectuses may be obtained by calling
1-800-645-6561. Except in the case of personal retirement plans, the shares
being exchanged must have a current value of at least $500; furthermore, when
establishing a new account by exchange, the shares being exchanged must have
a value of at least the minimum initial investment required for the fund into
which the exchange is being made. The ability to issue exchange instructions
by telephone is given to all Fund shareholders automatically, unless you
check the applicable "No" box on the Account Application, indicating that you
specifically refuse this Privilege. The Telephone Exchange Privilege may be
established for an existing account by written request signed by all
shareholders on the account, by a separate signed Shareholder Services Form,
available by calling 1-800-645-6561, or by oral request from any of the
authorized signatories on the account by calling 1-800-645-6561. If you have
established the Telephone Exchange Privilege, you may telephone exchange
instructions (including over The Dreyfus TouchRegistration Mark automated
telephone system)  by calling 1-800-645-6561. If you are calling from
overseas, call 516-794-5452. See "How to Redeem Shares_Procedures." Upon an
exchange into a new account, the following shareholder services and
privileges, as applicable and where available, will be automatically carried
over to the
                                    Page 10

fund into which the exchange is made: Telephone Exchange Privilege, Check
Redemption Privilege, Wire Redemption Privilege, Telephone Redemption
Privilege, Dreyfus TELETRANSFER Privilege and the dividend/capital gain
distribution option (except for Dreyfus Dividend Sweep) selected by the
investor.
    
   

        Shares will be exchanged at the next determined net asset value;
however, a sales load may be charged with respect to exchanges into funds
sold with a sales load. If you are exchanging into a fund that charges a
sales load, you may qualify for share prices which do not include the sales
load or which reflect a reduced sales load, if the shares you are exchanging
were: (a) purchased with a sales load, (b) acquired by a previous exchange
from shares purchased with a sales load, or (c) acquired through reinvestment
of dividends or distributions paid with respect to the foregoing categories
of shares. To qualify, at the time of the exchange you must notify the
Transfer Agent. Any such qualification is subject to confirmation of your
holdings through a check of appropriate records. See "Shareholder Services"
in the Statement of Additional Information. No fees currently are charged
shareholders directly in connection with exchanges, although the Fund
reserves the right, upon not less than 60 days' written notice, to charge
shareholders a nominal administrative fee in accordance with rules
promulgated by the Securities and Exchange Commission. The Fund reserves the
right to reject any exchange request in whole or in part. The availability of
Fund Exchanges may be modified or terminated at any time upon notice to
shareholders. See "Dividends, Distributions and Taxes."

you to invest regularly (on a semi-monthly, monthly, quarterly or annual
basis), in exchange for shares of the Fund, in shares of certain other funds
in the Dreyfus Family of Funds of which you are a shareholder. The amount you
designate, which can be expressed either in terms of a specific dollar or
share amount ($100 minimum), will be exchanged automatically on the first and
or fifteenth of the month according to the schedule you have selected. Shares
will be exchanged at the then-current net asset value; however, a sales load
may be charged with respect to exchanges into funds sold with a sales load.
See "Shareholder Services" in the Statement of Additional Information. The
right to exercise this Privilege may be modified or cancelled by the Fund or
the Transfer Agent. You may modify or cancel your exercise of this Privilege
at any time by mailing written notification to The Dreyfus Family of Funds,
P.O. Box 9671, Providence, Rhode Island 02940-9671. The Fund may charge a
service fee for the use of this Privilege. No such fee currently is
contemplated. For more information concerning this Privilege and the funds in

written notification to your employer. It is the sole responsibility of your
employer, not the Distributor, The Dreyfus Corporation, the Fund, the
Transfer Agent or any other person, to arrange for transactions under the
Dreyfus Payroll Savings Plan. The Fund may modify or terminate this Privilege
at any time or charge a service fee. No such fee currently is contemplated.

Government Direct Deposit Privilege or Dreyfus Payroll Savings Plan, as the
case may be, as provided under the terms of such Privilege(s). The Fund may
modify or terminate this Program at any time.
DREYFUS DIVIDEND OPTIONS -- Dreyfus Dividend Sweep enables you to invest
automatically dividends or dividends and capital gain distributions, if any,
paid by the Fund in shares of another fund in the Dreyfus Family of Funds of
which you are a shareholder. Shares of the other fund will be purchased at
the then-current net asset value; however, a sales load may be charged with
respect to investments in shares of a fund sold with a sales load. If you are
investing in a fund that charges a sales load, you may qualify for share
prices which do not include the sales load or which reflect a reduced sales
load. If you are investing in a fund that charges a contingent deferred sales
charge, the shares purchased will be subject on redemption to the contingent
deferred sales charge, if any, applicable to the purchased shares. See
"Shareholder Services" in the Statement of Additional Information. Dreyfus
Dividend ACH permits you to transfer electronically dividends or dividends
and capital gain distributions, if any, from the Fund to a designated bank
account. Only an account maintained at a domestic financial institution which
is an Automated Clearing House member may be so designated. Banks may charge
a fee for this service.

AUTOMATIC WITHDRAWAL PLAN -- The Automatic Withdrawal Plan permits you to
request withdrawal of a specified dollar amount (minimum of $50) on either a
monthly or quarterly basis if you have a $5,000 minimum account. An
application for the Automatic Withdrawal Plan can be obtained by calling
1-800-645-6561. The Automatic Withdrawal Plan may be ended at any time by
you, the Fund or the Transfer Agent. Shares for which certificates have been
issued may not be redeemed through the Automatic Withdrawal Plan.
                             HOW TO REDEEM SHARES
GENERAL
        You may request redemption of your shares at any time. Redemption
requests should be transmitted to the Transfer Agent as described below. When
a request is received in proper form, the Fund will redeem the shares at the
next determined net asset value.
   

        The Fund imposes no charges when shares are redeemed. Securities
dealers, banks and other financial institutions may charge their clients a
fee for effecting redemptions of Fund shares. Any certificates representing
Fund shares being redeemed must be submitted with the redemption request. The
value of the shares redeemed may be more or less than their original cost,
depending upon the Fund's then-current net asset value.
    

        The Fund ordinarily will make payment for all shares redeemed within
seven days after receipt by the Transfer Agent of a redemption request in
proper form, except as provided by the rules of the Securities and Exchange
Commission. HOWEVER, IF YOU HAVE PURCHASED FUND SHARES BY CHECK, BY DREYFUS
TELETRANSFER PRIVILEGE OR THROUGH DREYFUS-AUTOMATIC ASSET BUILDERRegistration
Mark AND SUBSEQUENTLY SUBMIT A WRITTEN REDEMPTION REQUEST TO THE TRANSFER
AGENT, YOUR REDEMPTION WILL BE EFFECTIVE AND THE REDEMPTION PROCEEDS WILL BE
TRANSMITTED TO YOU PROMPTLY UPON BANK CLEARANCE OF YOUR PURCHASE CHECK,
DREYFUS TELETRANSFER PURCHASE OR DREYFUS-AUTOMATIC ASSET BUILDER ORDER, WHICH
MAY TAKE UP TO EIGHT BUSINESS DAYS OR MORE. IN ADDITION, THE FUND WILL NOT
HONOR REDEMPTION CHECKS UNDER THE CHECK REDEMPTION PRIVILEGE, AND WILL REJECT
REQUESTS TO REDEEM SHARES BY WIRE OR TELEPHONE OR PURSUANT TO THE DREYFUS
TELETRANSFER PRIVILEGE, FOR A PERIOD OF EIGHT BUSINESS DAYS AFTER RECEIPT BY
THE TRANSFER AGENT OF THE PURCHASE CHECK, THE DREYFUS TELETRANSFER PURCHASE
OR THE DREYFUS-AUTOMATIC ASSET BUILDER ORDER AGAINST WHICH SUCH REDEMPTION IS
REQUESTED.  THESE PROCEDURES WILL NOT APPLY IF YOUR SHARES WERE PURCHASED BY
WIRE PAYMENT, OR IF YOU OTHERWISE HAVE A SUFFICIENT COLLECTED BALANCE IN YOUR
ACCOUNT TO COVER THE REDEMPTION REQUEST. PRIOR TO THE TIME ANY REDEMPTION IS
EFFECTIVE, DIVIDENDS ON SUCH SHARES WILL ACCRUE AND BE PAYABLE, AND YOU WILL
BE ENTITLED TO EXERCISE ALL OTHER RIGHTS OF BENEFICIAL OWNERSHIP. Fund shares
will not be redeemed until the Transfer Agent has received your Account
Application.
        The Fund reserves the right to redeem your account at its option upon
not less than 45 days' written notice if your account's net asset value is
$500 or less and remains so during the notice period.
                                    Page 13

PROCEDURES
        You may redeem shares by using the regular redemption procedure
through the Transfer Agent, or through the Telephone Redemption Privilege,
which is granted automatically unless you specifically refuse it by checking
the applicable "No" box on the Account Application. The Telephone Redemption
Privilege may be established for an existing account by a separate signed
Shareholder Services Form or by oral request from any of the authorized
signatories on the account by calling 1-800-645-6561. You also may redeem
shares through the Check Redemption Privilege, the Wire Redemption Privilege,
or the Dreyfus TeleTransfer Privilege, if you have checked the appropriate
box and supplied the necessary information on the Account Application or have
filed a Shareholder Services Form with the Transfer Agent. The Fund makes
available to certain large institutions the ability to issue redemption
instructions through compatible computer facilities. The Fund reserves the
right to refuse any request made by wire or telephone, including requests
made shortly after a change of address, and may limit the amount involved or
the number of such requests. The Fund may modify or terminate any redemption
Privilege at any time or charge a service fee upon notice to shareholders. No
such fee is currently contemplated. Shares for which certificates have been
issued are not eligible for the Check Redemption, Wire Redemption, Telephone
Redemption or Dreyfus TELETRANSFER Privilege.
   

        You may redeem shares by telephone if you have checked the
appropriate box on the Account Application or have filed a Shareholder
Services Form with the Transfer Agent. If you select the Telephone Redemption
Privilege or Telephone Exchange Privilege (which are granted automatically
unless you refuse them), you authorize the Transfer Agent to act on telephone
instructions (including over The Dreyfus TouchRegistration Mark automated
telephone system) from any person representing himself or herself to be you
and reasonably believed by the Transfer Agent to be genuine. The Fund will
require the Transfer Agent to employ reasonable procedures, such as requiring
a form of personal identification, to confirm that instructions are genuine
and, if it does not follow such procedures, the Fund or the Transfer Agent
may be liable for any losses due to unauthorized or fraudulent instructions.
Neither the Fund nor the Transfer Agent will be liable for following
telephone instructions reasonably believed to be genuine.
    

        During times of drastic economic or market conditions, you may
experience difficulty in contacting the Transfer Agent by telephone to
request a redemption or exchange of Fund shares. In such cases, you should
consider using the other redemption procedures described herein. Use of these
other redemption procedures may result in your redemption request being
processed at a later time than it would have been if telephone redemption had
been used.
REGULAR REDEMPTION -- Under the regular redemption procedure, you may redeem
shares by written request mailed to The Dreyfus Family of Funds, P.O. Box
9671, Providence, Rhode Island 02940-9671. Redemption requests may be
delivered in person only to a Dreyfus Financial Center. THESE REQUESTS WILL
BE FORWARDED TO THE FUND AND WILL BE PROCESSED ONLY UPON RECEIPT THEREBY. For
the location of the nearest Dreyfus Financial Center, please call one of the
telephone numbers listed under "General Information." Redemption requests
must be signed by each shareholder, including each owner of a joint account,
and each signature must be guaranteed. The Transfer Agent has adopted
standards and procedures pursuant to which signature-guarantees in proper
form generally will be accepted from domestic banks, brokers, dealers, credit
unions, national securities exchanges, registered securities associations,
clearing agencies and savings associations, as well as from participants in
the New York Stock Exchange Medallion Signature Program, the Securities
                                    Page 14

Transfer Agents Medallion Program ("STAMP"), and the Stock Exchanges
Medallion Program. If you have any questions with respect to
signature-guarantees, please call one of the telephone numbers listed under
"General Information."
        Redemption proceeds of at least $1,000 will be wired to any member
bank of the Federal Reserve System in accordance with a written
signature-guaranteed request.
CHECK REDEMPTION PRIVILEGE -- You may write Redemption Checks drawn on your
Fund account. Redemption Checks may be made payable to the order of any
person in the amount of $500 or more. Redemption Checks should not be used to
close your account. Redemption Checks are free, but the Transfer Agent will
impose a fee for stopping payment of a Redemption Check upon your request or
if the Transfer Agent cannot honor the Redemption Check due to insufficient
funds or other valid reason. You should date your Redemption Checks with the
current date when you write them. Please do not postdate your Redemption
Checks. If you do, the Transfer Agent will honor, upon presentment, even if
presented before the date of the check, all postdated Redemption Checks which
are dated within six months of presentment for payment, if they are otherwise
in good order.
WIRE REDEMPTION PRIVILEGE -- You may request by wire or telephone that
redemption proceeds (minimum $1,000) be wired to your account at a bank which
is a member of the Federal Reserve System, or a correspondent bank if your
bank is not a member. Holders of jointly registered Fund or bank accounts may
have redemption proceeds of not more than $250,000 wired within any 30-day
period. You may telephone redemption requests by calling 1-800-645-6561 or,
if you are calling from overseas, call 516-794-5452. The Statement of
Additional Information sets forth instructions for transmitting redemption
requests by wire.
TELEPHONE REDEMPTION PRIVILEGE -- You may request by telephone that
redemption proceeds (maximum $150,000 per day) be paid by check and mailed to
your address. You may telephone redemption instructions by calling
1-800-645-6561 or, if you are calling from overseas, call 516-794-5452. The
Telephone Redemption Privilege is granted automatically unless you refuse it.
DREYFUS TELETRANSFER PRIVILEGE -- You may request by telephone that
redemption proceeds (minimum $500 per day) be transferred between your Fund
account and your bank account. Only a bank account maintained in a domestic
financial institution which is an Automated Clearing House member may be
designated. Redemption proceeds will be on deposit in your account at an
Automated Clearing House member bank ordinarily two days after receipt of the
redemption request. Holders of jointly registered Fund or bank accounts may
redeem through the Dreyfus TELETRANSFER Privilege for transfer to their bank
account not more than $250,000 within any 30-day period.
        If you have selected the Dreyfus TELETRANSFER Privilege, you may
request a Dreyfus TELETRANSFER redemption of shares by calling 1-800-645-6561
or, if you are calling from overseas, call 516-794-5452.
                            SHAREHOLDER SERVICES PLAN
        The Fund has adopted a Shareholder Services Plan pursuant to which
the Fund reimburses Dreyfus Service Corporation, a wholly-owned subsidiary of
The Dreyfus Corporation, an amount not to exceed an annual rate of .25 of 1%
of the value of the Fund's average daily net assets for certain allocated
expenses of providing personal services and/or maintaining shareholder
accounts. The services provided may include personal services relating to
shareholder accounts, such as answering shareholder inquiries regarding the
Fund and providing reports and other information, and services related to the
maintenance of shareholder accounts.
                                    Page 15

                       DIVIDENDS, DISTRIBUTIONS AND TAXES
        The Fund ordinarily declares dividends from net investment income on
each day the New York Stock Exchange is open for business. The Fund's
earnings for Saturdays, Sundays and holidays are declared as dividends on the
next preceding business day. Dividends usually are paid on the last day of
each month, and are automatically reinvested in additional Fund shares at net
asset value or, at your option, paid in cash. If you redeem all shares in
your account at any time during the month, all dividends to which you are
entitled will be paid to you along with the proceeds of the redemption. If
you are an omnibus accountholder and indicate in a partial redemption request
that a portion of any accrued dividends to which such account is entitled
belongs to an underlying accountholder who has redeemed all shares in his or
her account, such portion of the accrued dividends will be paid to you along
with the proceeds of the redemption. Distributions from net realized
securities gains, if any, generally are declared and paid once a year, but
the Fund may make distributions on a more frequent basis to comply with the
distribution requirements of the Code, in all events in a manner consistent
with the provisions of the 1940 Act. The Fund will not make distributions from
 net realized securities gains unless capital loss carryovers, if any, have
been utilized or have expired. You may choose whether to receive
distributions in cash or to reinvest in additional Fund shares at net asset
value. All expenses are accrued daily and deducted before declaration of
dividends to investors.
          Dividends paid by the Fund to a Massachusetts resident are not
subject to Massachusetts personal income tax to the extent that the dividends
are attributable to interest income received by the Fund as interest from
Massachusetts Municipal Obligations as well as direct obligations of the
United States. The Fund believes that distributions by it to a Massachusetts
resident are not subject to the Massachusetts personal income tax to the
extent that distributions are attributable to gain from the sale of certain
Massachusetts Municipal Obligations, the gain from which is exempt from
Massachusetts personal income tax. Dividends and distributions by the Fund to
a Massachusetts resident that are attributable to most other sources are
subject to Massachusetts personal income tax. The Fund believes that
distributions from net realized long-term securities gains that are taxable
by Massachusetts are reportable as long-term capital gains, irrespective of
how long the resident has held shares in the Fund. Fund shares are not
subject to property taxation by Massachusetts or its political subdivisions.
          The foregoing discussion of Massachusetts personal income tax
consequences applies only to investors who are individuals residing in
Massachusetts. To the extent that investors are obligated to pay state or
local taxes outside of Massachusetts, dividends and distributions paid by the
Fund may represent taxable income.
        Except for dividends from Taxable Investments, the Fund anticipates
that substantially all dividends paid by the Fund will not be subject to
Federal income tax. Dividends derived from Taxable Investments, together with
distributions from any net realized short-term securities gains and all or a
portion of any gains realized from the sale or other disposition of certain
market discount bonds, paid by the Fund are subject to Federal income tax as
ordinary income whether or not reinvested in additional Fund shares. No
dividend paid by the Fund will qualify for the dividends received deduction
allowable to certain U.S. corporations. Distributions from net realized
long-term securities gains of the Fund generally are taxable as long-term
capital gains for Federal income tax purposes if you are a citizen or
resident of the United States. The Code provides that the net capital gain of
an individual generally will not be subject to Federal income tax at a rate
in excess of 28%. Under the Code, interest on indebtedness incurred or
continued to purchase or carry Fund shares which is deemed to relate to
exempt-interest dividends is not deductible.
                                    Page 16
   

        Although all or a substantial portion of the dividends paid by the
Fund may be excluded by shareholders of the Fund from their gross income for
Federal income tax purposes, the Fund may purchase specified private activity
bonds, the interest from which may be (i) a preference item for purposes of
the alternative minimum tax or (ii) a factor in determining the extent to
which a shareholder's Social Security benefits are taxable. If the Fund
purchases such securities, the portion of the Fund's dividends related
thereto will not necessarily be tax exempt to an investor who is subject to
the alternative minimum tax and/or tax on Social Security benefits and may
cause an investor to be subject to such taxes.
    

        Notice as to the tax status of your dividends and distributions will
be mailed to you annually. You also will receive periodic summaries of your
account which will include information as to dividends and distributions from
securities gains, if any, paid during the year. These statements set forth
the dollar amount of income exempt from Federal tax and the dollar amount, if
any, subject to Federal tax. These dollar amounts will vary depending on the
size and length of time of your investment in the Fund. If the Fund pays
dividends derived from taxable income, it intends to designate as taxable the
same percentage of the day's dividend as the actual taxable income earned on
that day bears to total income earned on that day. Thus, the percentage of
the dividend designated as taxable, if any, may vary from day to day.
        The exchange of shares of one fund for shares of another is treated
for Federal income tax purposes as a sale of the shares given in exchange by
the shareholder and, therefore, an exchanging shareholder may realize a
taxable gain or loss.
        Federal regulations generally require the Fund to withhold ("backup
withholding") and remit to the U.S. Treasury 31% of taxable dividends and
distributions from net realized securities gains paid to a shareholder of the
Fund if such shareholder fails to certify either that the TIN furnished in
connection with opening an account is correct, or such shareholder has not
received notice from the IRS of being subject to backup withholding as a
result of a failure to properly report taxable dividend or interest income on
a Federal income tax return. Furthermore, the IRS may notify the Fund to
institute backup withholding if the IRS determines a shareholder's TIN is
incorrect or if a shareholder has failed to properly report taxable dividend
and interest income on a Federal income tax return.
        A TIN is either the Social Security number or employer identification
number of the record owner of the account. Any tax withheld as a result of
backup withholding does not constitute an additional tax imposed on the
record owner of the account, and may be claimed as a credit on the record
owner's Federal income tax return.
        Management of the Fund believes that the Fund has qualified for the
fiscal year ended January 31, 1997 as a "regulated investment company" under
the Code. The Fund intends to continue to so qualify if such qualification is
in the best interests of its shareholders. Such qualification relieves the
Fund of any liability for Federal income tax to the extent its earnings are
distributed in accordance with applicable provisions of the Code. The Fund is
subject to a non-deductible 4% excise tax, measured with respect to certain
undistributed amounts of taxable investment income and capital gains.
        You should consult your tax adviser regarding specific questions as
to Federal, state or local taxes.
                            GENERAL INFORMATION
          The Fund was organized as an unincorporated business trust under
the laws of the Commonwealth of Massachusetts pursuant to an Agreement and
Declaration of Trust (the "Trust Agreement") dated September 12, 1990, and
commenced operations on March 1, 1991. The Trustees have authorized an
unlimited number of shares of beneficial interest, par value $.001 per share.
Each share has one vote.
                                    Page 17

          Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Fund.
However, the Trust Agreement disclaims shareholder liability for acts or
obligations of the Fund and requires that notice of such disclaimer be given
in each agreement, obligation or instrument entered into or executed by the
Fund or a Trustee. The Trust Agreement provides for indemnification from the
Fund's property for all losses and expenses of any shareholder held personally
 liable for the obligations of the Fund. Thus, the risk of a shareholder's
incurring financial loss on account of shareholder liability is limited to
circumstances in which the Fund itself would be unable to meet its
obligations, a possibility which management believes is remote. Upon payment
of any liability incurred by the Fund, the shareholder paying such liability
will be entitled to reimbursement from the general assets of the Fund. The
Fund intends to conduct its operations in such a way so as to avoid, as far
as possible, ultimate liability of the shareholders for liabilities of the
Fund. As discussed under "Management of the Fund" in the Statement of
Additional Information, the Fund ordinarily will not hold shareholder
meetings; however, shareholders under certain circumstances may have the
right to call a meeting of shareholders for the purpose of voting to remove
Trustees.
          The Transfer Agent maintains a record of your ownership and sends
confirmations and statements of account. Shareholder inquiries may be made by
writing to the Fund at 144 Glenn Curtiss Boulevard, Uniondale, New York
11556-0144, or by calling toll free 1-800-645-6561; in New York City, call
1-718-895-1206; outside the U.S. and Canada, call 516-794-5452.

                                    APPENDIX
INVESTMENT TECHNIQUES
BORROWING MONEY _ The Fund may borrow money from banks, but only for
temporary or emergency (not leveraging) purposes, in an amount up to 15% of
the value of its total assets (including the amount borrowed) valued at the
lesser of cost or market, less liabilities (not including the amount
borrowed) at the time the borrowing is made. While borrowings exceed 5% of
the Fund's total assets, the Fund will not make any additional investments.
   

FORWARD COMMITMENTS -- The Fund may purchase Municipal Obligations and other
securities on a forward commitment or when-issued basis, which means that
delivery and payment take place a number of days after the date of the
commitment to purchase. The payment obligation and the interest rate
receivable on a forward commitment or when-issued security are fixed when the
Fund enters into the commitment, but the Fund does not make payment until it
receives delivery from the counterparty. The Fund will commit to purchase
such securities only with the intention of actually acquiring the securities,
but the Fund may sell these securities before the settlement date if it is
deemed advisable. A segregated account of the Fund consisting of permissible
liquid assets at least equal at all times to the amount of the commitments
will be established and maintained at the Fund's custodian bank.
    

CERTAIN PORTFOLIO SECURITIES
CERTAIN TAX EXEMPT OBLIGATIONS -- The Fund may purchase floating and variable
rate demand notes and bonds, which are tax exempt obligations ordinarily
having stated maturities in excess of 13 months, but which permit the holder
to demand payment of principal at any time, or at specified intervals not
exceeding 13 months, in each case upon not more than 30 days' notice.
Variable rate demand notes include master demand notes which are obligations
that permit the Fund to invest fluctuating amounts at varying rates of
interest, pursuant to direct arrangements between the Fund, as lender, and
the borrower. These obligations permit daily changes in the amount borrowed.
Frequently, such obligations are secured by letters of credit or other credit
support arrangements provided by banks. Changes in the credit quality of
banks and other financial institutions that provide such credit or liquidity
enhancements to the Fund's portfolio securities could cause losses to the
Fund and affect its share price. Because these obligations are direct lending
arrangements between the lender and borrower, it is not contemplated that
such instruments generally will be traded, and there generally is no
established secondary market for these obligations, although they are
redeemable at face value plus accrued interest. Accordingly, where these
obligations are not secured by letters of credit or other credit support
arrangements, the Fund's right to redeem is dependent on the ability of the
borrower to pay principal and interest on demand. Each obligation purchased
by the Fund will meet the quality criteria established for the purchase of
Municipal Obligations.
   

TAX EXEMPT PARTICIPATION INTEREST _ The Fund may purchase from financial
institutions participation interests in Municipal Obligations (such as
industrial development bonds and municipal lease/purchase agreements). A
participation interest gives the Fund an undivided interest in the Municipal
Obligation in the proportion that the Fund's participation interest bears to
the total principal amount of the Municipal Obligation. These instruments may
have fixed, floating or variable rates of interest, with remaining maturities
of 13 months or less. If the participation interest is unrated, or has been
given a rating below that which otherwise is permissible for purchase by the
Fund, the participation interest will be backed by an irrevocable letter of
credit or guarantee of a bank that the Fund's Board has determined meets
prescribed quality standards for banks, or the payment obligation otherwise
will be collateralized by U.S. Government securities. For certain
participation interests, the Fund will have the right to demand payment, on
not more than seven
                                    Page 19

days' notice, for all or any part of the Fund's participation interest in the
Municipal Obligation, plus accrued interest. As to these instruments, the Fund
intends to exercise its right to demand payment only upon a default under the
terms of the Municipal Obligation, as needed to provide liquidity to meet
redemptions, or to maintain or improve the quality of its investment portfolio.
    

TENDER OPTION BONDS _ The Fund may purchase tender option bonds. A tender
option bond is a Municipal Obligation (generally held pursuant to a custodial
arrangement) having a relatively long maturity and bearing interest at a
fixed rate substantially higher than prevailing short-term tax exempt rates,
that has been coupled with the agreement of a third party, such as a bank,
broker-dealer or other financial institution, pursuant to which such
institution grants the security holders the option, at periodic intervals, to
tender their securities to the institution and receive the face value
thereof. As consideration for providing the option, the financial institution
receives periodic fees equal to the difference between the Municipal
Obligation's fixed coupon rate and the rate, as determined by a remarketing
or similar agent at or near the commencement of such period, that would cause
the securities, coupled with the tender option, to trade at par on the date
of such determination. Thus, after payment of this fee, the security holder
effectively holds a demand obligation that bears interest at the prevailing
short-term tax exempt rate. The Dreyfus Corporation, on behalf of the Fund,
will consider on an ongoing basis the creditworthiness of the issuer of the
underlying Municipal Obligations, of any custodian and of the third party
provider of the tender option. In certain instances and for certain tender
option bonds, the option may be terminable in the event of a default in
payment of principal or interest on the underlying Municipal Obligations and
for other reasons.
STAND-BY COMMITMENTS _ The Fund may acquire "stand-by commitments" with
respect to Municipal Obligations held in its portfolio. Under a stand-by
commitment, the Fund obligates a broker, dealer or bank to repurchase, at the
Fund's option, specified securities at a specified price and, in this
respect, stand-by commitments are comparable to put options. The exercise of
a stand-by commitment therefore is subject to the ability of the seller to
make payment on demand. The Fund will acquire stand-by commitments solely to
facilitate portfolio liquidity and does not intend to exercise its rights
thereunder for trading purposes. The Fund may pay for stand-by commitments if
such action is deemed necessary, thus increasing to a degree the cost of the
underlying Municipal Obligation and similarly decreasing such security's
yield to investors. Gains realized in connection with stand-by commitments
will be  taxable.
ILLIQUID SECURITIES -- The Fund may invest up to 10% of the value of its net
assets in securities as to which a liquid trading market does not exist,
provided such investments are consistent with the Fund's investment
objective. Such securities may include securities that are not readily
marketable, such as certain securities that are subject to legal or
contractual restrictions on resale, and repurchase agreements providing for
settlement in more than seven days after notice. As to these securities, the
Fund is subject to a risk that should the Fund desire to sell them when a
ready buyer is not available at a price the Fund deems representative of
their value, the value of the Fund's net assets could be adversely affected.
TAXABLE INVESTMENTS _ From time to time, on a temporary basis other than for
temporary defensive purposes (but not to exceed 20% of the value of the
Fund's net assets) or for temporary defensive purposes, the Fund may invest
in taxable short-term investments ("Taxable Investments") consisting of:
notes of issuers having, at the time of purchase, a quality rating within the
two highest grades of Moody's, S&P or Fitch; obligations of the U.S.
Government, its agencies or instrumentalities; commercial paper rated not
lower than P-2 by Moody's, A-2 by S&P or F-2 by Fitch; certificates of
deposit of U.S. domestic banks, including foreign branches of domestic banks,
with assets of one billion dollars or more; time deposits; bankers'
acceptances and other short-term bank obligations; and repurchase agree-
                                    Page 20

ments in respect of any of the foregoing. Dividends paid by the Fund that are
attributable to income earned by the Fund from Taxable Investments will be
taxable to investors. See "Dividends, Distributions and Taxes." Except for
temporary defensive purposes, at no time will more than 20% of the value of
the Fund's net assets be invested in Taxable Investments. If the Fund
purchases Taxable Investments, it will value them using the amortized cost
method and comply with the provisions of Rule 2a-7 relating to purchases of
taxable instruments. When the Fund has adopted a temporary defensive position,
including when acceptable Massachusetts Municipal Obligations are unavailable
for investment by the Fund, in excess of 35% of the Fund's net assets may be
invested in securities that are not exempt from Massachusetts income taxes.
Under normal market conditions, the Fund anticipates that not more than 5% of
the value of its total assets will be invested in any one category of Taxable
Investments. Taxable Investments are more fully described in the Statement of
Additional Information to which reference hereby is made.

     The following information supplements and should be read in conjunction
with the sections in the Fund's Prospectus entitled "Description of the Fund"
and "Appendix."

Portfolio Securities

     Municipal Obligations.  The average distribution of investments (at
value) in Municipal Obligations by ratings for the fiscal year ended January
31, 1997, computed on a monthly basis, was as follows:

Moody's             Standard             Fitch
Investors           & Poor's             Investors

                                                          100.0%
_______________________________
1    Of those securities which are not rated, all have been determined
     by the Manager to be of comparable quality to securities in the
     MIG 1/SP-1/F-1 rating category.

    

     The term "Municipal Obligations" generally includes debt obligations
issued to obtain funds for various public purposes, including the
construction of a wide range of public facilities such as airports, bridges,
highways, housing, hospitals, mass transportation, schools, streets and water
and sewer works.  Other public purposes for which Municipal Obligations may
be issued include refunding outstanding obligations, obtaining funds for
general operating expenses and lending such funds to other public
institutions and facilities.  In addition, certain types of industrial
development bonds are issued by or on behalf of public authorities to obtain
funds to provide for the construction, equipment, repair or improvement of
privately operated housing facilities, sports facilities, convention or trade
show facilities, airport, mass transit, industrial, port or parking
facilities, air or water pollution control facilities and certain local
facilities for water supply, gas, electricity, or sewage or solid waste
disposal; the interest paid on such obligations may be exempt from Federal
income tax, although current tax laws place substantial limitations on the
size of such issues.  Such obligations are considered to be Municipal
Obligations if the interest paid thereon qualifies as exempt from Federal
income tax in the opinion of bond counsel to the issuer.  There are, of
course, variations in the security of Municipal Obligations, both within a
particular classification and between classifications.

     Floating and variable rate demand notes and bonds are tax exempt
obligations ordinarily having stated maturities in excess of 13 months, but
which permit the holder to demand payment of principal at any time, or at
specified intervals not exceeding 13 months, in each case upon not more than
30 days' notice.  The issuer of such obligations ordinarily has a
corresponding right, after a given period, to prepay in its discretion the
outstanding principal amount of the obligations plus accrued interest upon a
specified number of days' notice to the holders thereof.  The interest rate
on a floating rate demand obligation is based on a known lending rate, such
as a bank's prime rate, and is adjusted automatically each time such rate is
adjusted.  The interest rate on a variable rate demand obligation is adjusted
automatically at specified intervals.

     The yields on Municipal Obligations are dependent on a variety of
factors, including general economic and monetary conditions, money market
factors, conditions in the Municipal Obligations market, size of a particular
offering, maturity of the obligation, and rating of the issue.  The
imposition of the Fund's management fee, as well as other operating expenses,
will have the effect of reducing the yield to investors.

     Municipal lease obligations or installment purchase contract obligations
(collectively, "lease obligations") have special risks not ordinarily
associated with Municipal Obligations.  Although lease obligations do not
constitute general obligations of the municipality for which the
municipality's taxing power is pledged, a lease obligation ordinarily is
backed by the municipality's covenant to budget for, appropriate and make the
payments due under the lease obligation.  However, certain lease obligations
contain "non-appropriation" clauses which provide that the municipality has
no obligation to make lease or installment purchase payments in future years
unless money is appropriated for such purpose on a yearly basis.  Although
"non-appropriation" lease obligations are secured by the leased property,
disposition of the property in the event of foreclosure might prove
difficult.  The Fund will seek to minimize these risks by investing only in
those lease obligations that (1) are rated in one of the two highest
categories for debt obligations by at least two nationally recognized
statistical rating organizations (or one rating organization if the lease
obligation was rated by only one such organization); or (2) if unrated, are
purchased principally from the issuer or domestic banks or other responsible
third parties, in each case only if the seller shall have entered into an
agreement with the Fund providing the seller or other responsible third party
will either remarket or repurchase the lease obligations within a short
period after demand by the Fund.  The staff of the Securities and Exchange
Commission currently considers certain lease obligations to be illiquid.
Accordingly, not more than 10% of the value of the Fund's net assets will be
invested in lease obligations that are illiquid and in other illiquid
securities.  See "Investment Restriction No. 11" below.

     The Fund will not purchase tender option bonds unless (a) the demand
feature applicable thereto is exercisable by the Fund within 13 months of the
date of such purchase upon no more than 30 days' notice and thereafter is
exercisable by the Fund no less frequently than annually upon no more than 30
days' notice and (b) at the time of such purchase, the Manager reasonably
expects (i) based upon its assessment of current and historical interest rate
trends, that prevailing short-term tax-exempt rates will not exceed the
stated interest rate on the underlying Municipal Obligations at the time of
the next tender fee adjustment and (ii) that the circumstances which might
entitle the grantor of a tender option to terminate the tender option would
not occur prior to the time of the next tender opportunity.  At the time of
each tender opportunity, the Fund will exercise the tender option with
respect to any tender option bonds unless the Manager reasonably expects, (x)
based upon its assessment of current and historical interest rate trends,
that prevailing short-term tax exempt rates will not exceed the stated
interest rate on the underlying Municipal Obligations at the time of the next
tender fee adjustment, and (y) that the circumstances which might entitle the
grantor of a tender option to terminate the tender option would not occur
prior to the time of the next tender opportunity.  The Fund will exercise the
tender feature with respect to tender option bonds, or otherwise dispose of
its tender option bonds, prior to the time the tender option is scheduled to
expire pursuant to the terms of the agreement under which the tender option
is granted.  The Fund otherwise will comply with the provisions of Rule 2a-7
in connection with the purchase of tender option bonds, including, without
limitation, the requisite determination by the Fund's Board that the tender
option bonds in question meet the quality standards described in Rule 2a-7,
which, in the case of a tender option bond subject to a conditional demand
feature, would include a determination that the security has received both
the required short-term and long-term quality rating or is determined to be
of comparable quality.  In the event of a default of the Municipal Obligation
underlying a tender option bond, or the termination of the tender option
agreement, the Fund would look to the maturity date of the underlying
security for purposes of compliance with Rule 2a-7 and, if its remaining
maturity was greater than 13 months, the Fund would sell the security as soon
as would be practicable.  The Fund will purchase tender option bonds only
when it is satisfied that the custodial and tender option arrangements,
including the fee payment arrangements, will not adversely affect the tax
exempt status of the underlying Municipal Obligations and that payment of any
tender fees will not have the effect of creating taxable income for the Fund.
Based on the tender option bond agreement, the Fund expects to be able to
value the tender option bond at par; however, the value of the instrument
will be monitored to assure that it is valued at fair value.

     Ratings of Municipal Obligations.  If, subsequent to its purchase by the
Fund, (a) an issue of rated Municipal Obligations ceases to be rated in the
highest rating category by at least two ratings organizations (or one rating
organization if the instrument was rated by only one such organization), or
the Fund's Board determines that it is no longer of comparable quality; or
(b) the Manager becomes aware that any portfolio security not so highly rated
or any unrated security has been given a rating by any rating organization
below the rating organization's second highest rating category, the Fund's
Board will reassess promptly whether such security presents minimal credit
risk and will cause the Fund to take such action as it determines is in the
best interest of the Fund and its shareholders, provided that the
reassessment required by clause (b) is not required if the portfolio security
is disposed of or matures within five business days of the Manager becoming
aware of the new rating and the Fund's Board is subsequently notified of the
Manager's actions.

     To the extent the ratings given by Moody's, S&P or Fitch for Municipal
Obligations may change as a result of changes in such organizations or their
rating systems, the Fund will attempt to use comparable ratings as standards
for its investments in accordance with the investment policies contained in
the Fund's Prospectus and this Statement of Additional Information.  The
ratings of Moody's, S&P and Fitch represent their opinions as to the quality
of the Municipal Obligations which they undertake to rate.  It should be
emphasized, however, that ratings are relative and subjective and are not
absolute standards of quality.  Although these ratings may be an initial
criterion for selection of portfolio investments, the Manager also will
evaluate these securities and the creditworthiness of the issuers of such
securities.

     Illiquid Securities.  Where a substantial market of qualified
institutional buyers develops for certain restricted securities purchased by
the Fund pursuant to Rule 144A under the Securities Act of 1933, as amended,
the Fund intends to treat such securities as liquid securities in accordance
with procedures approved by the Fund's Board.  Because it is not possible to
predict with assurance how the market for restricted securities pursuant to
Rule 144A will develop, the Fund's Board has directed the Manager to monitor
carefully the Fund's investments in such securities with particular regard to
trading activity, availability of reliable price information and other
relevant information.  To the extent that, for a period of time, qualified
institutional buyers cease purchasing restricted securities pursuant to Rule
144A, the Fund's investing in such securities may have the effect of
increasing the level of illiquidity in the Fund's portfolio during such
period.

     Taxable Investments.  Securities issued or guaranteed by the U.S.
Government or its agencies or instrumentalities include U.S. Treasury
securities, which differ in their interest rates, maturities and times of
issuance.  Some obligations issued or guaranteed by U.S. Government agencies
and instrumentalities are supported by the full faith and credit of the U.S.
Treasury; others by the right of the issuer to borrow from the U.S. Treasury;
others by discretionary authority of the U.S. Government to purchase certain
obligations of the agency or instrumentality; and others only by the credit
of the agency or instrumentality.  These securities bear fixed, floating or
variable rates of interest.  Interest rates may fluctuate based on generally
recognized reference rates or the relationship of rates.  While the U.S.
Government provides financial support to such U.S. Government-sponsored
agencies or instrumentalities, no assurance can be given that it will always
do so, since it is not so obligated by law.

     Commercial paper consists of short-term, unsecured promissory notes
issued to finance short-term credit needs.

     Certificates of deposit are negotiable certificates representing the
obligation of a bank to repay funds deposited with it for a specified period
of time.

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time (in no event longer than seven
days) at a stated interest rate.  Investments in time deposits generally are
limited to London branches of domestic banks that have total assets in excess
of one billion dollars.  Time deposits which may be held by the Fund will not
benefit from insurance from the Bank Insurance Fund or the Savings
Association Insurance Fund administered by the Federal Deposit Insurance
Corporation.

     Bankers' acceptances are credit instruments evidencing the obligation of
a bank to pay a draft drawn on it by a customer.  These instruments reflect
the obligation both of the bank and of the drawer to pay the face amount of
the instrument upon maturity.  Other short-term bank obligations may include
insured, direct obligations bearing fixed, floating or variable interest
rates.

     In a repurchase agreement, the Fund buys, and the seller agrees to
repurchase, a security at a mutually agreed upon time and price (usually
within seven days).  The repurchase agreement thereby determines the yield
during the purchaser's holding period, while the seller's obligation to
repurchase is secured by the value of the underlying security.  The Fund's
custodian or subcustodian will have custody of, and will hold in a segregated
account, securities acquired by the Fund under a repurchase agreement.
Repurchase agreements are considered by the staff of the Securities and
Exchange Commission to be loans by the Fund.  In an attempt to reduce the
risk of incurring a loss on a repurchase agreement, the Fund will enter into
repurchase agreements only with domestic banks with total assets in excess of
$1 billion, or primary government securities dealers reporting to the Federal
Reserve Bank of New York, with respect to securities of the type in which the
Fund may invest, and will require that additional securities be deposited
with it if the value of the securities purchased should decrease below resale
price.  Repurchase agreements could involve risks in the event of a default
or insolvency of the other party to the agreement, including possible delays
or restrictions upon the Fund's ability to dispose of the underlying
securities.

Management Policies

     Forward Commitments.  Municipal Obligations and other securities
purchased on a forward commitment or when-issued basis are subject to changes
in value (generally changing in the same way, i.e., appreciating when
interest rates decline and depreciating when interest rates rise) based upon
the public's perception of the creditworthiness of the issuer and changes,
real or anticipated, in the level of interest rates.  Securities purchased on
a forward commitment or when-issued basis may expose the Fund to risks
because they may experience such fluctuations prior to their actual delivery.
Purchasing securities on a when-issued basis can involve the additional risk
that the yield available in the market when the delivery takes place actually
may be higher than that obtained in the transaction itself.  Purchasing
securities on a forward commitment or when-issued basis when the Fund is
fully or almost fully invested may result in greater potential fluctuation in
the value of the Fund's net assets and its net asset value per share.

Investment Considerations and Risks
   

     Investing in Massachusetts Municipal Obligations.  Investors should
consider carefully the special risks inherent in the Fund's investment in
Massachusetts Municipal Obligations.  Since 1989, Massachusetts has
experienced growth rates significantly below the national average and an
economic recession in 1990 and 1991 caused negative growth rates in
Massachusetts.  Massachusetts' economic difficulties and fiscal problems in
the late 1980s and early 1990s caused several rating agencies to lower their
ratings of Massachusetts Municipal Obligations.  A return of persistent
serious financial difficulties could adversely affect the market values and
marketability of, or result in default in payment on, outstanding
Massachusetts Municipal Obligations.  Massachusetts' operating losses in
fiscal 1989 and 1990, which totalled $672 million and $1.25 billion,
respectively, were covered primarily through deficit borrowings, and the
fiscal 1991 operating loss of $21 million was covered by drawing on the
adjusted 1990 fund balance of $258 million.  Massachusetts ended fiscal years
1992 through 1996, however, with a positive fiscal balance in its general
operating funds.  Investors should review "Appendix A" which more fully sets
forth these and other risk factors.
    


Investment Restrictions

     The Fund has adopted investment restrictions numbered 1 through 10 as
fundamental policies, which cannot be changed without approval by the holders
of a majority (as defined in the Investment Company Act of 1940, as amended
(the "1940 Act")) of the Fund's outstanding voting shares.  Investment
restriction number 11 is not a fundamental policy and may be changed by a
vote of a majority of the Fund's Board members at any time.  The Fund may
not:

     1.        Purchase securities other than Municipal Obligations and Taxable
Investments as those terms are defined above and in the Prospectus.

     2.        Borrow money, except from banks for temporary or emergency (not
leveraging) purposes in an amount up to 15% of the value of the Fund's total
assets (including the amount borrowed) based on the lesser of cost or market,
less liabilities (not including the amount borrowed) at the time the
borrowing is made.  While borrowings exceed 5% of the value of the Fund's
total assets, the Fund will not make any additional investments.

     3.        Pledge, hypothecate, mortgage or otherwise encumber its assets,
except to secure borrowings for temporary or emergency purposes.

     4.        Sell securities short or purchase securities on margin.

     5.        Underwrite the securities of other issuers, except that the Fund
may bid separately or as part of a group for the purchase of Municipal
Obligations directly from an issuer for its own portfolio to take advantage
of the lower purchase price available.

     6.        Purchase or sell real estate, real estate investment trust
securities, commodities or commodity contracts, or oil and gas interests, but
this shall not prevent the Fund from investing in Municipal Obligations
secured by real estate or interests therein.

     7.        Make loans to others, except through the purchase of qualified
debt
obligations and the entry into repurchase agreements referred to above and in
the Fund's Prospectus.

     8.        Invest more than 25% of its total assets in the securities of
issuers in any single industry; provided that there shall be no such
limitation on the purchase of Municipal Obligations and, for temporary
defensive purposes, obligations issued or guaranteed by the U.S. Government,
its agencies or instrumentalities.

     9.        Invest in companies for the purpose of exercising control.


     10.       Invest in securities of other investment companies, except as
they may be acquired as part of a merger, consolidation or acquisition of
assets.

     11.       Enter into repurchase agreements providing for settlement in more
than seven days after notice or purchase securities which are illiquid, if,
in the aggregate, more than 10% of its net assets would be so invested.

     For purposes of Investment Restriction No. 8, industrial development
bonds, where the payment of principal and interest is the ultimate
responsibility of companies within the same industry, are grouped together as
an "industry."  If a percentage restriction is adhered to at the time of
investment, a later increase or decrease in percentage resulting from a
change in values or assets will not constitute a violation of such
restriction.

     The Fund may make commitments more restrictive than the restrictions
listed above so as to permit the sale of Fund shares in certain states.
Should the Fund determine that a commitment is no longer in the best
interests of the Fund and its shareholders, the Fund reserves the right to
revoke the commitment by terminating the sale of Fund shares in the state
involved.

     The Fund typically pays its Board members an annual retainer and a per
meeting fee and reimburses them for their expenses.  The Chairman of the
Board receives an additional 25% of such compensation.  Emeritus Board
members are entitled to receive an annual retainer and a per meeting fee of
one-half the amount paid to them as Board members.  The aggregate amount of
compensation paid to each Board member by the Fund for the fiscal year ended
January 31, 1997, and by all other funds in the Dreyfus Family of Funds for
which such person is a Board member (the number of which is set forth in
parenthesis next to each Board member's total compensation) for the year
ended December 31, 1996, were as follows:

                      MANAGEMENT AGREEMENT

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Management of the Fund."

     The Manager provides management services pursuant to the Management
Agreement (the "Agreement") dated August 24, 1994 with the Fund, which is
subject to annual approval by (i) the Fund's Board or (ii) vote of a majority
(as defined in the 1940 Act) of the outstanding voting securities of the
Fund, provided that in either event the continuance also is approved by a
majority of the Board members who are not "interested persons" (as defined in
the 1940 Act) of the Fund or the Manager, by vote cast in person at a meeting
called for the purpose of voting on such approval.  The Agreement was
approved by shareholders on August 2, 1994, and was last approved by the
Fund's Board, including a majority of the Board members who are not
"interested persons" of any party to the Agreement, at a meeting held on
January 15, 1997. The Agreement is terminable without penalty, on 60 days'
notice, by the Fund's Board or by vote of the holders of a majority of the
Fund's shares, or, on not less than 90 days' notice, by the Manager.  The
Agreement will terminate automatically in the event of its assignment (as
defined in the 1940 Act).
   

     The following persons are officers and/or directors of the Manager:  W.
Keith Smith, Chairman of the Board; Christopher M. Condron, President, Chief
Executive Officer, Chief Operating Officer, and a director; Stephen E.
Canter, Vice Chairman, Chief Investment Officer and a director; Lawrence S.
Kash, Vice Chairman--Distribution and a director; William T. Sandalls, Jr.,
Senior Vice President and Chief Financial Officer; Mark N. Jacobs, Vice
President, General Counsel, and Secretary; Patrice M. Kozlowski, Vice
President--Corporate Communication; Jeffrey N. Nachman, Vice President--
Mutual Fund Accounting; Andrew S. Wasser, Vice President--Information
Services; Mary Beth Leibig, Vice President--Human Resources; William V.
Healey, Assistant Secretary; and Mandell L. Berman, Burton C. Borgelt, and
Frank V. Cahouet, directors.
    


     The Manager manages the Fund's portfolio of investments in accordance
with the stated policies of the Fund, subject to the approval of the Fund's
Board.  The Manager is responsible for investment decisions, and provides the
Fund with portfolio managers who are authorized by the Board to execute
purchases and sales of securities.  The Fund's portfolio managers are Richard
J. Moynihan, Joseph P. Darcy, A. Paul Disdier, Douglas J. Gaylor, Karen M.
Hand, Stephen C. Kris, Jill C. Shaffro, Samuel J. Weinstock and Monica S.
Wieboldt.  The Manager also maintains a research department with a
professional staff of portfolio managers and securities analysts who provide
research services for the Fund as well as for other funds advised by the
Manager.  All purchases and sales are reported for the Board's review at the
meeting subsequent to such transactions.

     The Manager maintains office facilities on behalf of the Fund, and
furnishes statistical and research data, clerical help, accounting, data
processing, bookkeeping and internal auditing and certain other required
services of the Fund.  The Manager also may make such advertising and
promotional expenditures, using its own resources, as it from time to time
deems appropriate.

     All expenses incurred in the operation of the Fund are borne by the
Fund, except to the extent specifically assumed by the Manager.  The expenses
borne by the Fund include: taxes, interest, brokerage fees and commissions,
if any, fees of Board members who are not officers, directors, employees or
holders of 5% or more of the outstanding voting securities of the Manager,
Securities and Exchange Commission fees, state Blue Sky qualification fees,
advisory fees, charges of custodians, transfer and dividend disbursing
agents' fees, certain insurance premiums, industry association fees, outside
auditing and legal expenses, costs of maintaining corporate existence, costs
of independent pricing services, costs attributable to investor services
(including, without limitation, telephone and personnel expenses), costs of
shareholders' reports and corporate meetings, costs of preparing and printing
prospectuses and statements of additional information for regulatory purposes
and for distribution to existing shareholders, and any extraordinary
expenses.
   

     As compensation for the Manager's services, the Fund has agreed to pay
the Manager a monthly management fee at the annual rate of .50 of 1% of the
value of the Fund's average daily net assets.  All fees and expenses are
accrued daily and deducted before the declaration of dividends to
shareholders.  For the fiscal years ended January 31, 1995, 1996 and 1997,
the management fee payable by the Fund amounted to $582,460, $773,902, and
$883,683, respectively, which amounts were reduced by $531,751, $298,221, and
$119,605, respectively, pursuant to undertakings then in effect, resulting in
a net management fee paid to the Manager of $50,709 in fiscal 1995, $475,681
in fiscal 1995 and 1996, and $764,078 being paid in fiscal 1997.
    


     The Manager has agreed that if in any fiscal year the aggregate expenses
of the Fund, exclusive of taxes, brokerage, interest on borrowings and (with
the prior written consent of the necessary state securities commissions)
extraordinary expenses, but including the management fee, exceed the expense
limitation of any state having jurisdiction over the Fund, the Fund may
deduct from the payment to be made to the Manager under the Agreement, or the
Manager will bear, such excess expense to the extent required by state law.
Such deduction or payment, if any, will be estimated daily, and reconciled
and effected or paid, as the case may be, on a monthly basis.

     The aggregate of the fees payable to the Manager is not subject to
reduction as the value of the Fund's net assets increases.


                       PURCHASE OF SHARES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "How to Buy Shares."
   

     The Distributor.  The Distributor serves as the Fund's distributor on a
best efforts basis pursuant to an agreement which is renewable annually.  The
Distributor also acts as distributor for the other funds in the Dreyfus
Family of Funds and for certain other investment companies.  In some states,
certain financial institutions effecting transactions in Fund shares may be
required to register as dealers pursuant to state law.
    


     Using Federal Funds.  Dreyfus Transfer, Inc., the Fund's transfer and
dividend disbursing agent (the "Transfer Agent"), or the Fund may attempt to
notify the investor upon receipt of checks drawn on banks that are not
members of the Federal Reserve System as to the possible delay in conversion
into Federal Funds and may attempt to arrange for a better means of
transmitting the money.  If the investor is a customer of a securities
dealer, bank or other financial institution and his order to purchase Fund
shares is paid for other than in Federal Funds, the securities dealer, bank
or other financial institution acting on behalf of its customer, will
complete the conversion into, or itself advance, Federal Funds generally on
the business day following receipt of the customer order.  The order is
effective only when so converted and received by the Transfer Agent.  An
order for the purchase of Fund shares placed by an investor with sufficient
Federal Funds or cash balance in his brokerage account with a securities
dealer, bank or other financial institution will become effective on the day
that the order, including Federal Funds, is received by the Transfer Agent.

     Dreyfus TeleTransfer Privilege.  Dreyfus TeleTransfer purchase orders
may be made at any time.  Purchase orders received by 4:00 p.m., New York
time, on any business day that the Transfer Agent and the New York Stock
Exchange are open will be credited to the shareholder's Fund account on the
next bank business day following such purchase order.  Purchase orders made
after 4:00 p.m., New York time, on any business day the Transfer Agent and
the New York Stock Exchange are open for business, or orders made on
Saturday, Sunday or any Fund holiday (e.g., when the New York Stock Exchange
is not open for business), will be credited to the shareholder's Fund account
on the second bank business day following such purchase order.  To qualify to
use the Dreyfus TeleTransfer Privilege, the initial payment for purchase of
Fund shares must be drawn on, and redemption proceeds paid to, the same bank
and account as are designated on the Account Application or Shareholder
Services Form on file.  If the proceeds of a particular redemption are to be
wired to an account at any other bank, the request must be in writing and
signature-guaranteed.  See "Redemption of Shares--Dreyfus TeleTransfer
Privilege."
   

     Transactions Through Securities Dealers.  Fund shares may be purchased
and redeemed through securities dealers which may charge a fee for such
services.  Some dealers will place the Fund's shares in an account with their
firm.  Dealers also may require that the customer invest more than the $1,000
minimum investment; the customer not take physical delivery of stock
certificates; the customer not request redemption checks to be issued in the
customer's name; fractional shares not be purchased; monthly income
distributions be taken in cash; or other conditions.
    


     There is no sales or service charge by the Fund or the Distributor,
although investment dealers, banks and other institutions may make reasonable
charges to investors for their services.  The services provided and the
applicable fees are established by each dealer or other institution acting
independently of the Fund.  The Fund has been given to understand that these
fees may be charged for customer services including, but not limited to, same-
day investment of client funds; same-day access to client funds; advice to
customers about the status of their accounts, yield currently being paid or
income earned to date; provision of periodic account statements showing
security and money market positions; other services available from the
dealer, bank or other institution; and assistance with inquiries related to
their investment.  Any such fees will be deducted monthly from the investor's
account, which on smaller accounts could constitute a substantial portion of
distributions.  Small, inactive, long-term accounts involving monthly service
charges may not be in the best interest of investors.  Investors should be
aware that they may purchase shares of the Fund directly from the Fund
without imposition of any maintenance or service charges, other than those
already described herein.

     Reopening an Account.  An investor may reopen an account with a minimum
investment of $100 without filing a new Account Application during the
calendar year the account is closed or during the following calendar year,
provided the information on the old Account Application is still applicable.


                   SHAREHOLDER SERVICES PLAN

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Shareholder Services
Plan."

     The Fund has adopted a Shareholder Services Plan (the "Plan"), pursuant
to which the Fund reimburses Dreyfus Service Corporation for certain
allocated expenses of providing personal services and/or maintaining
shareholder accounts.  The services provided may include personal services
relating to shareholder accounts, such as answering shareholder inquiries
regarding the Fund and providing reports and other information, and services
related to the maintenance of shareholder accounts.

     A quarterly report of the amounts expended under the Plan, and the
purposes for which such expenditures were incurred, must be made to the Board
for its review.  In addition, the Plan provides that material amendments of
the Plan must be approved by the Board, and by the Board members who are not
"interested persons" (as defined in the 1940 Act) of the Fund and have no
direct or indirect financial interest in the operation of the Plan, by vote
cast in person at a meeting called for the purpose of considering such
amendments.  The Plan is subject to annual approval by such vote of the Board
members cast in person at a meeting called for the purpose of voting on the
Plan.  The Plan was last so approved on April 16, 1997.  The Plan is
terminable at any time by vote of a majority of the Board members who are not
"interested persons" and who have no direct or indirect financial interest in
the operation of the Plan.

     For the fiscal year ended January 31, 1997, $84,083 was paid by the Fund
under the Plan.


                      REDEMPTION OF SHARES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "How to Redeem Shares."
   

     Check Redemption Privilege.  An investor may indicate on the Account
Application, Shareholder Services Form or by later written request that the
Fund provide Redemption Checks ("Checks") drawn on the investor's Fund
account.  Checks will be sent only to the registered owner(s) of the account
and only to the address of record.  The Account Application, Shareholder
Services Form, or later written request must be manually signed by the
registered owner(s).  Checks may be made payable to the order of any person
in an amount of $500 or more.  When a Check is presented to the Transfer
Agent for payment, the Transfer Agent, as the investor's agent, will cause
the Fund to redeem a sufficient number of shares in the investor's account to
cover the amount of the Check.  Dividends are earned until the Check clears.
After clearance, a copy of the Check will be returned to the investor.
Investors generally will be subject to the same rules and regulations that
apply to checking accounts, although election of this Privilege creates only
a shareholder-transfer agent relationship with the Transfer Agent.
    


     If the amount of the Check is greater than the value of the shares in an
investor's account, the Check will be returned marked insufficient funds.
Checks should not be used to close an account.

     Wire Redemption Privilege.  By using this Privilege, the investor
authorizes the Transfer Agent to act on wire or telephone redemption
instructions from any person representing himself or herself to be the
investor, and reasonably believed by the Transfer Agent to be genuine.
Ordinarily, the Fund will initiate payment for shares redeemed pursuant to
this Privilege on the same business day if the Transfer Agent receives the
redemption request in proper form prior to Noon on such day; otherwise the
Fund will initiate payment on the next business day.  Redemption proceeds
($1,000 minimum) will be transferred by Federal Reserve wire only to the
commercial bank account specified by the investor on the Account Application
or Shareholder Services Form, or to a correspondent bank if the investor's
bank is not a member of the Federal Reserve System.  Fees ordinarily are
imposed by such bank and borne by the investor.  Immediate notification by
the correspondent bank to the investor's bank is necessary to avoid a delay
in crediting the funds to the investor's bank account.

     Investors with access to telegraphic equipment may wire redemption
requests to the Transfer Agent by employing the following transmittal code
which may be used for domestic or overseas transmissions:

                                             Transfer Agent's
          Transmittal Code                   Answer Back Sign

              114295                         144295 TSSG PREP

     Investors who do not have direct access to telegraphic equipment may
have the wire transmitted by contacting a TRT Cables operator at 1-800-654-
7171, toll free.  Investors should advise the operator that the above
transmittal code must be used and should also inform the operator of the
Transfer Agent's answer back sign.

     To change the commercial bank or account designated to receive wire
redemption proceeds, a written request must be sent to the Transfer Agent.
This request must be sent to the Transfer Agent.  This request must be signed
by each shareholder, with each signature guaranteed as described below under
"Share Certificates; Signatures."

     Dreyfus TeleTransfer Privilege.  Investors should be aware that if they
have selected the Dreyfus TeleTransfer Privilege, any request for a wire
redemption will be effected as a Dreyfus TeleTransfer transaction through the
Automated Clearing House ("ACH") system unless more prompt transmittal
specifically is requested.  Redemption proceeds will be on deposit in the
investor's account at an ACH member bank ordinarily two business days after
receipt of the redemption request.  See "Purchase of Shares--Dreyfus
TeleTransfer Privilege."

     Share Certificates; Signatures.  Any certificates representing Fund
shares to be redeemed must be submitted with the redemption request.  Written
redemption requests must be signed by each shareholder, including each holder
of a joint account, and each signature must be guaranteed.  Signatures on
endorsed certificates submitted for redemption also must be guaranteed.  The
Transfer Agent has adopted standards and procedures pursuant to which
signature-guarantees in proper form generally will be accepted from domestic
banks, brokers, dealers, credit unions, national securities exchanges,
registered securities associations, clearing agencies and savings
associations, as well as from participants in the New York Stock Exchange
Medallion Signature Program, the Securities Transfer Agents Medallion Program
("STAMP") and the Stock Exchanges Medallion Program.  Guarantees must be
signed by an authorized signatory of the guarantor and "Signature-Guaranteed"
must appear with the signature.  The Transfer Agent may request additional
documentation from corporations, executors, administrators, trustees or guard
ians, and may accept other suitable verification arrangements from foreign
investors, such as consular verification.  For more information with respect
to signature-guarantees, please call one of the telephone numbers listed on
the cover.

     Redemption Commitment.  The Fund has committed itself to pay in cash all
redemption requests by any shareholder of record, limited in amount during
any 90-day period to the lesser of $250,000 or 1% of the value of the Fund's
net assets at the beginning of such period. Such commitment is irrevocable
without the prior approval of the Securities and Exchange Commission.  In the
case of requests for redemption in excess of such amount, the Fund's Board
reserves the right to make payments in whole or in part in securities
(including non-marketable securities) or other assets in case of an emergency
or any time a cash distribution would impair the liquidity of the Fund to the
detriment of the existing shareholders.  In such event, the securities would
be valued in the same manner as the Fund's portfolio is valued.  If the
recipient sold such securities, brokerage charges incurred.

     Suspension of Redemptions.  The right of redemption may be suspended or
the date of payment postponed (a) during any period when the New York Stock
Exchange is closed (other than customary weekend and holiday closings), (b)
when trading in the markets the Fund ordinarily utilizes is restricted, or
when an emergency exists as determined by the Securities and Exchange
Commission so that disposal of the Fund's investments or determination of its
net asset value is not reasonably practicable, or (c) for such other periods
as the Securities and Exchange Commission by order may permit to protect the
Fund's shareholders.


                      SHAREHOLDER SERVICES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Shareholder Services."

     Fund Exchanges.  Shares of other funds purchased by exchange will be
purchased on the basis of relative net asset value per share as follows:

     A.   Exchanges for shares of funds that are offered without a sales
          load will be made without a sales load.

     B.   Shares of funds purchased without a sales load may be
          exchanged for shares of other funds sold with a sales load, and the
          applicable sales load will be deducted.

     C.   Shares of funds purchased with a sales load may be exchanged without a
          sales load for shares of other funds sold without a sales load.

     D.   Shares of funds purchased with a sales load, shares of funds acquired
          by a previous exchange from shares purchased with a sales
          load and additional shares acquired through reinvestment of
          dividends or distributions of any such funds (collectively referred
          to herein as "Purchased Shares") may be exchanged for shares of
          other funds sold with a sales load (referred to herein as "Offered
          Shares"), provided that, if the sales load applicable to the
          Offered Shares exceeds the maximum sales load that could have been
          imposed in connection with the Purchased Shares (at the time the
          Purchased Shares were acquired), without giving effect to any
          reduced loads, the difference will be deducted.

     To accomplish an exchange under item D above, shareholders must notify
the Transfer Agent of their prior ownership of fund shares and their account
number.
   

     To request an exchange, an investor must give exchange instructions to
the Transfer Agent in writing or by telephone.  The ability to issue exchange
instructions by telephone is given to all Fund shareholders automatically,
unless the investor checks the applicable "No" box on the Account
Application, indicating that the investor specifically refuses this
Privilege. By using the Telephone Exchange Privilege, the investor authorizes
the Transfer Agent to act on telephonic instructions (including over The
Dreyfus Touchr automated telephone system) from any person representing
himself or herself to be the investor, and reasonably believed by the
Transfer Agent to be genuine.  Telephone exchanges may be subject to
limitations as to the amount involved or the number of telephone exchanges
permitted.  Shares issued in certificate form are not eligible for telephone
exchange.
    


     To establish a personal retirement plan by exchange, shares of the fund
being exchanged must have a value of at least the minimum initial investment
required for the fund into which the exchange is being made.  For Dreyfus-
sponsored Keogh Plans, IRAs and IRAs set up under a Simplified Employee
Pension Plan ("SEP-IRAs") with only one participant, the minimum initial
investment is $750.  To exchange shares held in corporate plans, 403(b)(7)
Plans and SEP-IRAs with more than one participant, the minimum initial
investment is $100 if the plan has at least $2,500 invested among the funds
in the Dreyfus Family of Funds.  To exchange shares held in personal
retirement plans, the shares exchanged must have a current value of at least
$100.

     Dreyfus Auto-Exchange Privilege.  Dreyfus Auto-Exchange Privilege
permits an investor to purchase, in exchange for shares of the Fund, shares
of another fund in the Dreyfus Family of Funds.  This Privilege is available
only for existing accounts.  Shares will be exchanged on the basis of
relative net asset value as described above under "Fund Exchanges."
Enrollment in or modification or cancellation of this Privilege is effective
three business days following notification by the investor.  An investor will
be notified if his account falls below the amount designated to be exchanged
under this Privilege.  In this case,  an investor's account will fall to zero
unless additional investments are made in excess of the designated amount
prior to the next Auto-Exchange transactions.  Shares held under IRA and
other retirements plans are eligible for this Privilege.  Exchanges of IRA
shares may be made between IRA accounts and from regular accounts to IRA
accounts, but not from IRA accounts to regular accounts.  With respect to all
other retirement accounts, exchanges may be made only among those accounts.

     Fund Exchanges and the Dreyfus Auto-Exchange Privilege are available to
shareholders residing in any state in which shares of the fund being acquired
may legally be sold.  Shares may be exchanged only between accounts having
identical names and other identifying designations.

     Shareholder Services Forms and prospectuses of the other funds may be
obtained by calling 1-800-645-6561.  The Fund reserves the right to reject
any exchange request in whole or in part.  The Fund Exchanges services or the
Dreyfus Auto-Exchange Privilege may be modified or terminated at any time
upon notice to shareholders.

     Automatic Withdrawal Plan.  The Automatic Withdrawal Plan permits an
investor with a $5,000 minimum account to request withdrawal of a specified
dollar amount (minimum of $50) on either a monthly or quarterly basis.
Withdrawal payments are the proceeds from sales of Fund shares, not the yield
on the shares.  If withdrawal payments exceed reinvested dividends and distri
butions, the investor's shares will be reduced and eventually may be
depleted.  Automatic Withdrawal may be terminated at any time by the
investor, the Fund or the Transfer Agent.  Shares for which certificates have
been issued may not be redeemed through the Automatic Withdrawal Plan.
   

          Dreyfus Dividend Sweep.  Dreyfus Dividend Sweep allows investors to
invest automatically their dividends or dividends and capital gain
distributions, if any, from the Fund in shares of another fund in the Dreyfus
Family of Funds of which the investor is a shareholder.  Shares of other
funds purchased pursuant to this privilege will be purchased on the basis of
relative net asset value per share as follows:
    


     A.   Dividends and distributions paid by a fund may be invested
          without imposition of a sales load in shares of other funds that
          are offered without a sales load.

     B.   Dividends and distributions paid by a fund which does not
          charge a sales load may be invested in shares of other funds sold
          with a sales load, and the applicable sales load will be deducted.

     C.   Dividends and distributions paid by a fund which charges a
          sales load may be invested in shares of other funds sold with a
          sales load (referred to herein as "Offered Shares"), provided that,
          if the sales load applicable to the Offered Shares exceeds the
          maximum sales load charged by the fund from which dividends or
          distributions are being swept, without giving effect to any reduced
          loads, the difference will be deducted.

     D.  Dividends and distributions paid by a fund may be invested in shares of
          other funds that impose a contingent deferred sales
          charge ("CDSC") and the applicable CDSC, if any, will be imposed
          upon redemption of such shares.


                DETERMINATION OF NET ASSET VALUE

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "How to Buy Shares."

     Amortized Cost Pricing.  The valuation of the Fund's portfolio
securities is based upon their amortized cost which does not take into
account unrealized capital gains or losses.  This involves valuing an
instrument at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuating
interest rates on the market value of the instrument.  While this method pro
vides certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price the Fund
would receive if it sold the instrument.

     The Fund's Board has established, as a particular responsibility within
the overall duty of care owed to the Fund's investors, procedures reasonably
designed to stabilize the Fund's price per share as computed for purposes of
purchases and redemptions at $1.00.  Such procedures include review of the
Fund's portfolio holdings by the Board, at such intervals as it deems appro
priate, to determine whether the Fund's net asset value calculated by using
available market quotations or market equivalents deviates from $1.00 per
share based on amortized cost.  Market quotations and market equivalents used
in such review are obtained from an independent pricing service (the
"Service") approved by the Board.  The Service values the Fund's investments
based on methods which include consideration of:  yields or prices of
municipal bonds of comparable quality, coupon, maturity and type; indications
of values from dealers; and general market conditions.  The Service also may
employ electronic data processing techniques and/or a matrix system to
determine valuations.

     The extent of any deviation between the Fund's net asset value based
upon available market quotations or market equivalents and $1.00 per share
based on amortized cost will be examined by the Board.  If such deviation
exceeds 1/2 of 1%, the Board will consider what actions, if any, will be
initiated.  In the event the Board determines that a deviation exists which
may result in material dilution or other unfair results to investors or
existing shareholders, it has agreed to take such corrective action as it
regards as necessary and appropriate, including:  selling portfolio
instruments prior to maturity to realize capital gains or losses or to
shorten average portfolio maturity; withholding dividends or paying distribu
tions from capital or capital gains; redeeming shares in kind; or establish
ing a net asset value per share by using available market quotations or
market equivalents.

     New York Stock Exchange Closings.  The holidays (as observed) on which
the New York Stock Exchange is closed currently are:  New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving and Christmas.


               DIVIDENDS, DISTRIBUTIONS AND TAXES

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Dividends, Distributions
and Taxes."

     Ordinarily, gains and losses realized from portfolio transactions will
be treated as capital gain or loss.  However, all or a portion of any gains
realized from the sale or other disposition of certain market discount bonds
will be treated as ordinary income under Section 1276 of the Internal Revenue
Code of 1986, as amended.


                       YIELD INFORMATION

     The following information supplements and should be read in conjunction
with the section in the Fund's Prospectus entitled "Yield Information."
   

     For the seven-day period ended January 31, 1997, the Fund's yield was
2.90% and effective yield was 2.94%.  These yields reflect the waiver of a
portion of the management fee, without which the Fund's yield and effective
yield for the seven-day period ended January 31, 1997 would have been 2.83%
and 2.87%, respectively.  Yield is computed in accordance with a standardized
method which involves determining the net change in the value of a
hypothetical pre-existing Fund account having a balance of one share at the
beginning of a seven calendar day period for which yield is to be quoted,
dividing the net change by the value of the account at the beginning of the
period to obtain the base period return, and annualizing the results (i.e.,
multiplying the base period return by 365/7).  The net change in the value of
the account reflects the value of additional shares purchased with dividends
declared on the original share and any such additional shares and fees that
may be charged to shareholder accounts, in proportion to the length of the
base period and the Fund's average account size, but does not include
realized gains and losses or unrealized appreciation and depreciation.
Effective yield is computed by adding 1 to the base period return (calculated
as described above), raising that sum to a power equal to 365 divided by 7,
and subtracting 1 from the result.
    
   

     Based upon a combined 1997 Federal and Commonwealth of Massachusetts
income tax rate (after giving effect to the Federal deduction for
Massachusetts taxes) of 46.85%, the Fund's tax equivalent yield for the seven-
day period ended January 31, 1997 was 5.46%.  Without the waiver of a portion
of the management fee discussed above then in effect, the Fund's tax
equivalent yield for the seven-day period ended January 31, 1997 would have
been 5.32%  Tax equivalent yield is computed by dividing that portion of the
yield or effective yield (calculated as described above) which is tax exempt
by 1 minus a stated tax rate and adding the quotient to that portion, if any,
of the yield of the Fund that is not tax exempt.
    


     The tax equivalent yield noted above represents the application of the
highest Federal and Massachusetts marginal personal income tax rates
presently in effect.  For Federal income tax purposes, a 39.60% tax rate has
been used.  For Massachusetts personal income tax purposes, a 12% tax rate
has been used.  The tax equivalent figure, however, does not reflect the
potential effect of any local (including, but not limited to, county,
district or city) taxes, including applicable surcharges.  In addition, there
may be pending legislation which could affect such stated tax rates or yield.
Each investor should consult its tax adviser, and consider its own factual
circumstances and applicable tax laws, in order to ascertain the relevant tax
equivalent yield.

     Yields fluctuate and are not necessarily representative of future
results.  The investor should remember that yield is a function of the type
and quality of the instruments in the portfolio, portfolio maturity, and
operating expenses.  An investor's principal in the Fund is not guaranteed.
See "Determination of Net Asset Value" for a discussion of the manner in
which the Fund's price per share is determined.

     From time to time, the Fund may use hypothetical tax equivalent yields
or charts in its advertising.  These hypothetical yields or charts will be
used for illustrative purposes only and not as representative of the Fund's
past or future performance.

     Advertising materials for the Fund also may refer to or discuss then-
current or past economic conditions, developments, and/or events, and actual
or proposed tax legislation.  From time to time, advertising materials for
the Fund may also refer to statistical or other information concerning trends
relating to investment companies, as compiled by industry associations such
as the Investment Company Institute.


                     PORTFOLIO TRANSACTIONS

     Portfolio securities ordinarily are purchased from and sold to parties
acting as either principal or agent.  Newly-issued securities ordinarily are
purchased directly from the issuer or from an underwriter; other purchases
and sales usually are placed with those dealers from which it appears that
the best price or execution will be obtained.  Usually no brokerage
commissions, as such, are paid by the Fund for such purchases and sales,
although the price paid usually includes an undisclosed compensation to the
dealer acting as agent.  The prices paid to underwriters of newly-issued
securities usually include a concession paid by the issuer to the
underwriter, and purchases of after-market securities from dealers ordinarily
are executed at a price between the bid and asked price.  No brokerage
commissions have been paid by the Fund to date.

     Transactions are allocated to various dealers by the Fund's portfolio
managers in their best judgment.  The primary consideration is prompt and
effective execution of orders at the most favorable price.  Subject to that
primary consideration, dealers may be selected for research, statistical or
other services to enable the Manager to supplement its own research and
analysis with the views and information of other securities firms.

     Research services furnished by brokers through which the Fund effects
securities transactions may be used by the Manager in advising other funds it
advises and, conversely, research services furnished to the Manager by
brokers in connection with other funds the Manager advises may be used by the
Manager in advising the Fund.  Although it is not possible to place a dollar
value on these services, it is the opinion of the Manager that the receipt
and study of such services should not reduce the overall expenses of its
research department.


                   INFORMATION ABOUT THE FUND

                    RISK FACTORS - INVESTING
             IN MASSACHUSETTS MUNICIPAL OBLIGATIONS
    
   
     The following information constitutes only a brief summary, does not
purport to be a complete description, and is based on information drawn from
official statements relating to securities offerings of the Commonwealth of
Massachusetts available as of the date of this Statement of Additional
Information.  While the Fund has not independently verified this information,
it has no reason to believe that such information is not correct in all
material aspects.
    
   
     The economy of the Commonwealth of Massachusetts is experiencing
recovery following a slowdown that began in mid-1988.  Massachusetts had
benefitted from an annual job growth rate of approximately 2% since the early
1980s, but by 1989 employment started to decline.  Between 1988 and 1992,
total employment in Massachusetts declined 10.7%.  In 1993, 1994 and 1995,
however, total employment increased by 1.6%, 2.2% and 2.4% respectively.
Employment levels increased in all sectors except manufacturing.  Between
1990 and 1992, the Commonwealth's unemployment rate was considerably higher
than the national average, however, unemployment rates in Massachusetts since
1993 have declined faster than the national average (6.9% compared to 6.8% in
1993) and the employment rate in Massachusetts in 1994 and 1995 was slightly
below the national average (6.0% compared to 6.1% for 1994 and 5.4% compared
with 5.6% for 1995).  The unemployment rate in Massachusetts fell to 3.9% in
November 1996, compared with the national average of 5.4%.
    
   
     While the Commonwealth's expenditures for State programs and services in
each of the fiscal years 1987 through 1991 exceeded each year's current
revenues, Massachusetts ended each of the fiscal years 1991 to 1996 with a
positive closing fund balance in its budgeted operating funds.
    
   
     In recent years, health related costs have risen dramatically in
Massachusetts and across the nation and the increase in the State's Medicaid
and group health insurance costs reflects this trend.  In fiscal 1993,
Medicaid was the largest item in Massachusetts' budget and has been one of
the fastest growing budget items, although the rate of increase has abated in
recent years.  During fiscal years 1989, 1990, 1991 and 1992, Medicaid
expenditures were $1.83 billion, $2.12 billion, $2.77 billion and $2.82
billion, respectively, representing and average annual increase of 15.4%.
Expenditures for fiscal 1993 were $3.15 billion, an 11.8% increase over
fiscal 1992.  Medicaid expenses in fiscal 1994 were $3.31 billion and in
fiscal 1995 $3.398 billion.  The average annual growth from fiscal 1991 to
fiscal 1995 was 5.4% compared with approximately 17% between fiscal 1987 and
fiscal 1991.
    
   
     Massachusetts' pension costs have risen dramatically as the State has
appropriated funds to address in part the unfunded liabilities that had
accumulated over several decades.  Total pension costs increased at an
average rate of 8.1% from $703.9 million in fiscal 1991 to $968.8 million in
fiscal 1995.
    
   
     Payments for debt service on Massachusetts general obligation bonds and
notes have risen at an average annual rate of 11.6% from $649.8 million in
fiscal 1989 to $1.23 billion in fiscal 1995.  Debt service payments were
$898.3 million in fiscal 1992, $1.14 billion in fiscal 1993 and $1.15 billion
in fiscal 1994.  In 1990, legislation was enacted which generally imposes a
10% limit on the total appropriations in any fiscal year that may be expended
for payment of interest and principal on general obligation debt.  As of
January 1, 1995, the State had approximately $9,595 billion of long-term
general obligation debt outstanding and short-term direct obligations of the
Commonwealth totalled $264 million.
    
   
     Certain independent authorities and agencies within the State are
statutorily authorized to use debt for which Massachusetts is directly, in
whole or in part, or indirectly liable.  The State's liabilities are either
in the form of (i) a direct guaranty, (ii) State support through contract
assistance payments for debt service, or (iii) indirect obligations.  The
State is indirectly liable for the debt of certain authorities through a
moral obligation to maintain the funding of reserve funds which are pledged
as security for the authorities' debt.
    
   
     In November 1980, voters in the Commonwealth approved a State-wide tax
limitation initiative petition, commonly known as Proposition 2-1/2, to
constrain levels of property taxation and to limit the charges and fees
imposed on cities and towns by certain government entities, including county
governments.  The law is not a constitutional provision and accordingly is
subject to amendment or repeal by the legislature.  Proposition 2-1/2 limits
the property taxes which a Massachusetts city or town may assess in any
fiscal year to the lesser of (i) 2.5% of the full and fair cash value of real
estate and personal property therein and (ii) 2.5% over the previous year's
levy limit plus any growth in the tax base from certain new construction and
parcel subdivisions.  In addition, Proposition 2-1/2 limits any increase in the
charges and fees assessed by certain governmental entities, including county
governments, on cities and towns to the sum of (i) 2.5% of the total charges
and fees imposed in the proceeding fiscal year, and (ii) any increase in
charges for services customarily provided locally or services obtained by the
city or town at its option.  The law contains certain override provisions
which require voter approval at a general or special election.  Propositions
2-1/2 also limits any annual increase in the total assessments on cities and
towns by any county, district, authority, the Commonwealth, or any other
governmental entity except regional school districts and regional water and
sewer districts whose budgets are approved by 2/3 of their member cities and
towns.  During the 1980s, Massachusetts increased payments to the cities,
towns and regional school districts ("Local Aid") to mitigate the impact of
Proposition 2-1/2 on local programs and services.  In fiscal 1996, approximately
19.1% of Massachusetts' budget was allocated to Local Aid.  Direct Local Aid
dropped from a high of $2.961 billion in fiscal 1989 to $2.727 billion in
fiscal 1994, but increased to $2.976 billion in fiscal 1995 and an estimated
$3.240 billion in fiscal 1996.  Recent increases are largely a result of
comprehensive education reform legislation enacted in 1993 that requires
annual increase in state expenditures for education funding, subject to
annual legislative appropriations, above a fiscal 1993 base of approximately
$1.288 billion.  Increases of $175 million above the base for fiscal 1994 to
$867 million for fiscal 1997 have been fully funded.  Additional increases
are called for in future years.
    
   
     Many factors affect the financial condition of the Commonwealth and its
cities, towns and public bodies, such as social, environmental, and economic
conditions, many of which are not within the control of such entities.  As is
the case with most urban States, the continuation of many of Massachusetts'
programs, particularly its human services programs, is in significant part
dependent upon continuing Federal reimbursements which have been steadily
declining.  The loss of grants to Massachusetts and its cities and towns
could further slow economic development.  To the extent that such factors may
exist, they could have an adverse effect on economic conditions in
Massachusetts, although what effects, if any, such factors would have on
Massachusetts' Municipal Obligations cannot be predicted.
    



                           APPENDIX B

     Description of S&P, Moody's and Fitch ratings:

S&P

Municipal Bond Ratings

     An S&P municipal bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation.

     The ratings are based on current information furnished by the issuer or
obtained by S&P from other sources it considers reliable, and will include:
(1) likelihood of default-capacity and willingness of the obligor as to the
timely payment of interest and repayment of principal in accordance with the
terms of the obligation; (2) nature and provisions of the obligation; and
(3) protection afforded by, and relative position of, the obligation in the
event of bankruptcy, reorganization or other arrangement under the laws of
bankruptcy and other laws affecting creditors' rights.

                              AAA

     Debt rated AAA has the highest rating assigned by S&P.  Capacity to pay
interest and repay principal is extremely strong.

                               AA

     Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.
The AA ratings may be modified by the addition of a plus (+) or a minus (-)
sign, which is used to show relative standing within the category.

Municipal Note Ratings

                              SP-1

     The issuers of these municipal notes exhibit very strong or strong
capacity to pay principal and interest.  Those issues determined to possess
overwhelming safety characteristics are given a plus (+) designation.

                              SP-2

     The issuers of these municipal notes exhibit satisfactory capacity to
pay principal and interest.


Commercial Paper Ratings

     The designation A-1 by S&P indicates that the degree of safety regarding
timely payment is either overwhelming or very strong.  Those issues
determined to possess overwhelming safety characteristics are denoted with a
plus (+) sign designation.  Capacity for timely payment on issues with an A-2
designation is strong.  However, the relative degree of safety is not as high
as for issues designated A-1.

Moody's

Municipal Bond Ratings

                              Aaa

     Bonds which are rated Aaa are judged to be of the best quality.  They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge."  Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure.  While the various
protective elements are likely to change, such changes as can be visualized
are most unlikely to impair the fundamentally strong position of such issues.

                               Aa
   

     Bonds which are rated Aa are judged to be of high quality by all
standards.  Together with the Aaa group they comprise what generally are
known as high grade bonds.  They are rated lower than the best bonds because
margins of protection may not be as large as in Aaa securities or fluctuation
of protective elements may be of greater amplitude or there may be other
elements present which make the long-term risks appear somewhat larger than
in Aaa securities.  Generally, Moody's provides either a generic rating or a
rating with a numerical modifier of 1 for bonds in the generic rating
category Aa.  Moody's also provides numerical modifiers of 2 and 3 in this
category for bond issues in the health care, higher education and other not-
for-profit sectors; the modifier 1 indicates that the issue ranks in the
higher end of that generic rating category; the modifier 2 indicates that the
issue is in the mid-range of that generic category; and the modifier 3
indicates that the issue is in the low end of that generic  category.
    



Municipal Note Ratings

     Moody's ratings for state and municipal notes and other short-term loans
are designated Moody's Investment Grade (MIG).  Such ratings recognize the
difference between short-term credit risk and long-term risk.  Factors
affecting the liquidity of the borrower and short-term cyclical elements are
critical in short-term ratings, while other factors of major importance in
bond risk, long-term secular trends for example, may be less important over
the short run.

     A short-term rating may also be assigned on an issue having a demand
feature.  Such ratings will be designated as VMIG or, if the demand feature
is not rated, as NR.  Short-term ratings on issues with demand features are
differentiated by the use of the VMIG symbol to reflect such characteristics
as payment upon periodic demand rather than fixed maturity dates and payment
relying on external liquidity.  Additionally, investors should be alert to
the fact that the source of payment may be limited to the external liquidity
with no or limited legal recourse to the issuer in the event the demand is
not met.

     Moody's short-term ratings are designated Moody's Investment Grade as
MIG 1 or VMIG 1 through MIG 4 or VMIG 4.  As the name implies, when Moody's
assigns a MIG or VMIG rating, all categories define an investment grade
situation.

                          MIG 1/VMIG 1

     This designation denotes best quality.  There is present strong
protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.

                          MIG 2/VMIG 2

     This designation denotes high quality.  Margins of protection are ample
although not so large as in the preceding group.

Commercial Paper Ratings

     The rating Prime-1 (P-1) is the highest commercial paper rating assigned
by Moody's.  Issuers of P-1 paper must have a superior capacity for repayment
of short-term promissory obligations, and ordinarily will be evidenced by
leading market positions in well established industries, high rates of return
on funds employed, conservative capitalization structures with moderate
reliance on debt and ample asset protection, broad margins in earnings
coverage of fixed financial charges and high internal cash generation, and
well established access to a range of financial markets and assured sources
of alternate liquidity. Issuers rated Prime-2 (P-2) have a strong ability for
repayment of senior short-term debt obligations.  Capitalization
characteristics, while still appropriate, may be more affected by external
conditions.  Ample alternate liquidity is maintained.

Fitch

Municipal Bond Ratings

     The ratings represent Fitch's assessment of the issuer's ability to meet
the obligations of a specific debt issue or class of debt.  The ratings take
into consideration special features of the issue, its relationship to other
obligations of the issuer, the current financial condition and operative
performance of the issuer and of any guarantor, as well as the political and
economic environment that might affect the issuer's future financial strength
and credit quality.

                              AAA

     Bonds rated AAA are considered to be investment grade and of the highest
credit quality.  The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

                               AA

     Bonds rated AA are considered to be investment grade and of very high
credit quality.  The obligor's ability to apply interest and repay principal
is very strong, although not quite as strong as bonds rated AAA.  Because
bonds rated in the AAA and AA categories are not significantly vulnerable to
foreseeable future developments, short-term debt of these issuers is
generally rated F-1+.  Plus (+) and minus (-) signs are used with a rating
symbol to indicate the relative position of a credit within the rating
category.

Short-Term Ratings

     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and
investment notes.

     Although the credit analysis is similar to Fitch's bond rating analysis,
the short-term rating places greater emphasis than bond ratings on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.

Short-Term Ratings

                              F-1+

Exceptionally Strong Credit Quality.  Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

                              F-1

Very Strong Credit Quality.  Issues assigned this rating reflect an assurance
of timely payment only slightly less in degree than issues rated F-1+.

                              F-2

Good Credit Quality.  Issues carrying this rating have a satisfactory degree
of assurance for timely payment, but the margin of safety is not as great as
the F-1+ and F-1 categories.

Item 27.    Indemnification
_______     _______________

        Reference is made to Article EIGHTH of the Registrant's Agreement and
Declaration of Trust.  The application of these provisions is limited by
Article 10 of the Registrant's By-Laws, and by the following undertaking set
forth in the rules promulgated by the Securities and Exchange Commission:

          Insofar as indemnification for liabilities arising under the
        Securities Act of 1933 may be permitted to trustees, officers and
        controlling persons of the registrant pursuant to the foregoing
        provisions, or otherwise, the registrant has been advised that in
        the opinion of the Securities and Exchange Commission such
        indemnification is against public policy as expressed in such Act as
        is, therefore, unenforceable.  In the event that a claim for
        indemnification against such liabilities (other than the    payment
        by the registrant of expenses incurred or paid by a trustee, officer
        or controlling person of the registration in the successful defense
        of any action, suitor proceeding) is asserted by such trustee,
        officer or controlling person in connection with the securities
        being registered, the registrant will, unless in the opinion of its
        counsel the matter has been settled by controlling precedent, submit
        to a court of appropriate jurisdiction the question whether such
        indemnification by it is against public policy as expressed in such
        Act and will be governed by the final adjudication of such issue.

           Reference is also made to the Distribution Agreement, which is
        incorporated by reference to Exhibit (6) of Post-Effective Amendment
        No. 6 to the Registration Statement, filed on March 23, 1995.
