RISK/RETURN SUMMARY


       1.  WHAT IS THE FUND'S OBJECTIVE?
           The Fund seeks current interest income, safety of capital
           and flexibility by investing for approximately 7 years in a
           fixed, laddered portfolio of U.S. Treasury notes maturing
           each year 2005-2006.
       2.  WHAT ARE U.S. TREASURY NOTES?
           These are directly issued by the U.S. Treasury and are
           similar to corporate bonds in that they pay interest
           semi-annually. They are issued to fund various government
           activities. In return, they pay a fixed rate of interest
           and principal at maturity.
       3.  WHAT IS THE FUND'S INVESTMENT STRATEGY?
        O  The Fund plans to hold to maturity 2 intermediate-term U.S.
           Treasury notes with a current aggregate face amount of
           $7,948,000. The Fund is a unit investment trust which means
           that, unlike a mutual fund, the Fund's portfolio is not
           managed.
        o  You will periodically receive your share of the principal
           received as each Treasury note matures.
        o  The securities but not the Fund or the units are backed by
           the full faith and credit of the United States.
        o  100% of the Portfolio consists of United States government
           Treasury notes.



       4.  WHAT ARE THE SIGNIFICANT RISKS?
           YOU CAN LOSE MONEY BY INVESTING IN THE FUND. THIS CAN HAPPEN
           FOR VARIOUS REASONS, INCLUDING:
        o  Rising interest rates can reduce the price of your units.
        o  Assuming no changes in interest rates, when you sell your
           units, they will generally be worth less than your cost
           because your cost included a sales fee.
        o  The Fund will receive early returns of principal if
           securities are sold before they mature. If this happens your
           income will decline and you may not be able to reinvest the
           money you receive at as high a yield or as long a maturity.

       5.  IS THIS FUND APPROPRIATE FOR YOU?
           Yes, if you want current monthly income exempt from state
           and local personal income taxes in all states. You will
           benefit from a professionally selected and supervised
           portfolio of U.S. government backed securities.
           The Fund is not appropriate for you if you want a
           speculative investment that changes to take advantage of
           market movements.


           DEFINING YOUR INCOME

           WHAT YOU MAY EXPECT (Payable on the 25th day each month):


           Regular Monthly Income per 1,000 units:           $    7.89
           Annual Income per 1,000 units:                    $   94.72
           RECORD DAY: 10th day of each month
           These figures are estimates on the evaluation date; actual
           payments may vary.



       6.  WHAT ARE THE FUND'S FEES AND EXPENSES?
           This table shows the costs and expenses you may pay,
           directly or indirectly, when you invest in the Fund.



           INVESTOR FEES
                                                                    %
           Maximum Sales Fee (Load) on new purchases (as a
           percentage of $1,000 invested)



           Employees of some of the Sponsors and their affiliates may
           be charged a reduced sales fee of no less than $5.00 per
           1,000 Units.
           The maximum sales fee is reduced if you invest at least
           $1,000,000, as follows:



                                                     YOUR MAXIMUM
                                                        SALES FEE
                     IF YOU INVEST:                      WILL BE:
           -----------------------------------  -------------------------

           TOTAL



           The Sponsors historically paid updating expenses.
       7.  IS THE FUND MANAGED?
           Unlike a mutual fund, the Fund is not managed and
           securities are not sold because of market changes. Rather,
           experienced Defined Asset Funds financial analysts
           regularly review the securities in the Fund. The Fund may
           sell a security if certain adverse credit or other
           conditions exist.
       8.  HOW DO I BUY UNITS?
           The minimum investment is $250.
           You can buy units from any of the Sponsors and other
           broker-dealers. The Sponsors are listed later in this
           prospectus. Some banks may offer units for sale through
           special arrangements with the Sponsors, although certain
           legal restrictions may apply.
           UNIT PRICE PER 1,000 UNITS           $1,239.45
           (as of May 31, 1999)
           Unit price is based on the net asset value of the Fund
           plus the up-front sales fee. An amount equal to any
           principal cash, as well as net accrued but undistributed
           interest on the unit, is added to the unit price. An
           independent evaluator prices the bonds at 3:30 p.m.
           Eastern time every business day. Unit price changes every
           day with changes in the prices of the bonds in the Fund.

       9.  HOW DO I SELL UNITS?
           You may sell your units at any time to any Sponsor or the
           Trustee for the net asset value determined at the close of
           business on the date of sale. You will not pay any other
           fee when you sell your units.
      10.  HOW ARE DISTRIBUTIONS MADE AND TAXED?
           The Fund pays income monthly. Interest on the bonds in
           this Fund is subject to federal income taxes for U.S.
           investors, but exempt from state and local personal income
           taxes. If you are a non-U.S. investor, your interest may
           be exempt from U.S. federal income taxes, including
           withholding taxes.
           You will also receive principal payments when the
           securities mature or if they are sold (when the cash
           available is more than $5.00 per 1,000 units. You will be
           subject to tax on any gain realized by the Fund on the
           disposition of bonds.
      11.  WHAT OTHER SERVICES ARE AVAILABLE?
           EXCHANGE PRIVILEGES
           You may exchange units of this Fund for units of certain
           other Defined Asset Funds. You may also exchange into this
           Fund from certain other funds. We charge a reduced sales
           fee on exchanges.
           REINVESTMENT
           You will receive your monthly income in cash unless you
           choose to compound your income by reinvesting into
           additional units of the Fund at no sales fee. Contact your
           broker, dealer or financial institution.


CHECKWRITING

You may request checkwriting privileges from the Trustee. Checks must be written
for at least $500, and you may not receive certificates for your units.

WHAT YOU CAN EXPECT FROM YOUR INVESTMENT

MONTHLY INCOME

The Fund will pay you regular monthly income. Your monthly income may vary
because of:
   o elimination of one or more securities from the Fund's portfolio because of
      redemptions or sales; or
   o a change in the Fund's expenses;

Changes in interest rates generally will not affect your monthly income because
the portfolio is fixed.

Along with your monthly income, you will receive your share of any available
principal.

RETURN FIGURES

We cannot predict your actual return, which will vary with unit price, how long
you hold your investment and changes in the portfolio, interest income and
expenses.

Estimated Current Return equals the estimated annual cash to be received from
the securities in the Fund less estimated annual Fund expenses, divided by the
Unit Price (including the maximum sales fee):


 Estimated Annual                  Estimated
 Interest Income        -       Annual Expenses
- -------------------------------------------------
                   Unit Price


Estimated Long Term Return is a measure of the estimated return over the
estimated life of the Fund. Unlike Estimated Current Return, Estimated Long Term
Return reflects maturities, discounts and premiums of the securities in the
Fund. It is an average of the yields to maturity of the individual securities in
the portfolio, adjusted to reflect the Fund's maximum sales fee and estimated
expenses. We calculate the average yield for the portfolio by weighting each
security's yield by its market value and the time remaining to the maturity
date.

Yields on individual securities depend on many factors including general
conditions of the bond markets, the size of a particular offering and the
maturity and quality rating of the particular issues. Yields can vary among
bonds with similar maturities, coupons and ratings.

These return quotations are designed to be comparative rather than predictive.

RECORDS AND REPORTS

You will receive:
o a monthly statement of income payments and any principal payments;
o a notice from the Trustee when new securities are deposited in exchange or
   substitution for securities originally deposited;
o an annual report on Fund activity; and
o annual tax information. This will also be sent to the IRS. You must report the
  amount of interest received during the year.

You may request:
o copies of evaluations to enable you to comply with federal and state tax
  reporting requirements; and
o audited financial statements of the Fund.

You may inspect records of Fund transactions at the Trustee's office during
regular business hours.

THE RISKS YOU FACE

INTEREST RATE RISK

Investing involves risks, including the risk that your investment will decline
in value if interest rates rise. Generally, securities with longer maturities
will change in value more than securities with shorter maturities. Of course, we
cannot predict how interest rates may change.

REDUCED DIVERSIFICATION RISK

If many investors sell their units, the Fund will have to sell securities. This
could reduce the diversification of your investment and increase your share of
Fund expenses.

LITIGATION RISK

We do not know of any pending litigation that might have a material adverse
effect upon the Fund.

SELLING OR EXCHANGING UNITS

You can sell your units at any time for a price based on net asset value. Your
net asset value is calculated each business day by:
   o adding the value of the securities, net accrued interest, cash and any
     other Fund assets;
   o subtracting accrued but unpaid Fund expenses, unreimbursed Trustee
      advances, cash held to buy back units or for distribution to investors and
     any other Fund liabilities; and
   o dividing the result by the number of outstanding units.

Your net asset value when you sell may be more or less than your cost because of
sales fees, market movements and changes in the portfolio.

SPONSORS' SECONDARY MARKET

While we are not obligated to do so, we will buy back units at net asset value
without any other fee or charge. We may resell the units to other buyers or to
the Trustee. You should consult your financial professional for current market
prices to determine if other broker-dealers or banks are offering higher prices.

We have maintained a secondary market continuously for over 25 years, but we
could discontinue it without prior notice for any business reason.

SELLING UNITS TO THE TRUSTEE

Regardless of whether we maintain a secondary market, you can sell your units to
the Trustee at any time by sending the Trustee a letter (with any outstanding
certificates if you hold Unit certificates). You must properly endorse your
certificates (or execute a written transfer instrument with signatures
guaranteed by an eligible institution). Sometimes, additional documents are
needed such as a trust document, certificate of corporate authority, certificate
of death or appointment as executor, administrator or guardian.

Within seven days after your request and the necessary documents are received,
the Trustee will mail a check to you. Contact the Trustee for additional
information.

As long as we are maintaining a secondary market, the Trustee will sell your
units to us at a price based on net asset value. If there is no secondary
market, the Trustee may sell your units in the over-the-counter market for a
higher price, but it is not obligated to do so. In that case, you will receive
the net proceeds of the sale.

                                       6
<PAGE>
If the Fund does not have cash available to pay you for units you are selling,
the agent for the Sponsors will select securities to be sold. Securities will be
selected based on market and credit factors. These sales could be made at times
when the securities would not otherwise be sold and may result in your receiving
less than the unit par value and also reduce the size and diversity of the Fund.

There could be a delay in paying you for your units:
   o if the New York Stock Exchange is closed (other than customary weekend and
      holiday closings);
   o if the SEC determines that trading on the New York Stock Exchange is
     restricted or that an emergency exists making sale or evaluation of the
     bonds not reasonably practicable; and
   o for any other period permitted by SEC order.

EXCHANGE OPTION

You may exchange units of certain Defined Asset Funds for units of this Fund at
a maximum exchange fee of      %. You may exchange units of this Fund for units
of certain other funds at a reduced sales fee if your investment goals change.
To exchange units, you should talk to your financial professional about what
funds are exchangeable, suitable and currently available.

Normally, an exchange is taxable and you must recognize any gain or loss on the
exchange. However, the IRS may try to disallow a loss if the portfolios of the
two funds are not materially different; you should consult your own tax adviser.

We may amend or terminate this exchange option at any time without notice.

HOW THE FUND WORKS

PRICING

The price of a unit includes interest accrued on the securities, less expenses,
from the most recent Record Day up to, but not including, the settlement date,
which is usually three business days after the purchase date of the unit.

A portion of the price of a unit consists of cash so that the Trustee can
provide you with regular monthly income. When you sell your units you will
receive your share of this cash.

EVALUATIONS

An independent Evaluator values the securities on each business day (excluding
Saturdays, Sundays and the following holidays as observed by the New York Stock
Exchange: New Year's Day, Presidents' Day, Martin Luther King, Jr. Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas;
and the following federal holidays: Columbus Day and Veterans Day). Values are
based on current bid or offer prices for the securities or comparable bonds. In
the past, the difference between bid and offer prices of U.S. Treasury
securities of the type in this Fund has been about 0.10%.

INCOME

The Trustee credits interest to an Income Account and other receipts to a
Capital Account. The Trustee may establish a Reserve Account by withdrawing from
these accounts amounts it considers appropriate to pay any

                                       7
<PAGE>
material liability. These accounts do not bear interest.

EXPENSES

The Trustee is paid monthly. It also benefits when it holds cash for the Fund in
non-interest bearing accounts. The Trustee may also receive additional amounts:
   o to reimburse the Trustee for the Fund's operating expenses;
   o for extraordinary services and costs of indemnifying the Trustee and the
      Sponsors;
   o costs of actions taken to protect the Fund and other legal fees and
     expenses;
   o expenses for keeping the Fund's registration statement current; and
   o Fund termination expenses and any governmental charges.

The Sponsors are currently reimbursed up to 45 cents per $1,000 face amount
annually for providing portfolio supervisory, bookkeeping and administrative
services and for any other expenses properly chargeable to the Fund. Legal,
typesetting, electronic filing and regulatory filing fees and expenses
associated with updating the Portfolio's registration statement yearly are also
now chargeable to the Portfolio. While this fee may exceed the amount of these
costs and expenses attributable to this Fund, the total of these fees for all
Series of Defined Asset Funds will not exceed the aggregate amount attributable
to all of these Series for any calendar year. The Fund also pays the Evaluator's
fees.

The Trustee's, Sponsors' and Evaluator's fees may be adjusted for inflation
without investors' approval.

The Sponsors will pay advertising and selling expenses at no charge to the Fund.
If Fund expenses exceed initial estimates, the Fund will owe the excess. The
Trustee has a lien on Fund assets to secure reimbursement of Fund expenses and
may sell bonds if cash is not available.

PORTFOLIO CHANGES

The Sponsors and Trustee are not liable for any default or defect in a security.

Unlike a mutual fund, the portfolio is designed to remain intact and we may keep
securities in the portfolio even if their credit quality declines or other
adverse financial circumstances occur. However, we may sell a security in
certain cases if we believe that certain adverse credit or certain other
conditions exist.

If we maintain a secondary market in units but are unable to sell the units that
we buy in the secondary market, we will redeem units, which will affect the size
and composition of the portfolio. Units offered in the secondary market may not
represent the same face amount of securities that they did originally.

We decide whether or not to offer units for sale that we acquire in the
secondary market after reviewing:
   o diversity of the portfolio;
   o size of the Fund relative to its original size;
   o ratio of Fund expenses to income;
   o current and long-term returns;
   o degree to which units may be selling at a premium over par; and
   o cost of maintaining a current prospectus.

                                       8
<PAGE>
FUND TERMINATION

The Fund will terminate following the stated maturity or sale of the last
security in the portfolio. The Fund may also terminate earlier with the consent
of investors holding 51% of the units or if total assets of the Fund have fallen
below 40% of the face amount of securities deposited. We will decide whether to
terminate the Fund early based on the same factors used in deciding whether or
not to offer units in the secondary market.

When the Fund is about to terminate you will receive a notice, and you will be
unable to sell your units after that time. On or shortly before termination, we
will sell any remaining securities, and you will receive your final
distribution. Any security that cannot be sold at a reasonable price may
continue to be held by the Trustee in a liquidating trust pending its final
sale.

You will pay your share of the expenses associated with termination, including
brokerage costs in selling securities. This may reduce the amount you receive as
your final distribution.

CERTIFICATES

Certificates for units are issued on request. You may transfer certificates by
complying with the requirements for redeeming certificates, described above. You
can replace lost or mutilated certificates by delivering satisfactory indemnity
and paying the associated costs.

TRUST INDENTURE

The Fund is a 'unit investment trust' governed by a Trust Indenture, a contract
among the Sponsors, the Trustee and the Evaluator, which sets forth their duties
and obligations and your rights. A copy of the Indenture is available to you on
request to the Trustee. The following summarizes certain provisions of the
Indenture.

The Sponsors and the Trustee may amend the Indenture without your consent:
   o to cure ambiguities;
   o to correct or supplement any defective or inconsistent provision;
   o to make any amendment required by any governmental agency; or
   o to make other changes determined not to be materially adverse to your best
     interest (as determined by the Sponsors).
Investors holding 51% of the units may amend the Indenture. Every investor must
consent to any amendment that changes the 51% requirement. No amendment may
reduce your interest in the Fund without your written consent.

The Trustee may resign by notifying the Sponsors. The Sponsors may remove the
Trustee without your consent if:
   o it fails to perform its duties and the Sponsors determine that its
     replacement is in your best interest; or
   o it becomes incapable of acting or bankrupt or its affairs are taken over by
      public authorities.

Investors holding 51% of the units may remove the Trustee. The Evaluator may
resign or be removed by the Sponsors and the Trustee without the consent of
investors. The resignation or removal of either becomes effective when a
successor accepts appointment. The Sponsors will try to appoint a successor
promptly; however, if no successor has accepted within 30 days after notice of

                                       9
<PAGE>
resignation, the resigning Trustee or Evaluator may petition a court to appoint
a successor.

Any Sponsor may resign as long as one Sponsor with a net worth of $2 million
remains and agrees to the resignation. The remaining Sponsors and the Trustee
may appoint a replacement. If there is only one Sponsor and it fails to perform
its duties or becomes bankrupt the Trustee may:
   o remove it and appoint a replacement Sponsor;
   o liquidate the Fund; or
   o continue to act as Trustee without a Sponsor.

Merrill Lynch, Pierce, Fenner & Smith Incorporated acts as agent for the
Sponsors.

The Trust Indenture contains customary provisions limiting the liability of the
Trustee, the Sponsors and the Evaluator.

LEGAL OPINION

Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017, as
special counsel for the Sponsors, has given an opinion that the units are
validly issued.

AUDITORS

Deloitte & Touche LLP, 2 World Financial Center, New York, New York 10281,
independent accountants, audited the Statement of Condition included in this
prospectus.

SPONSORS

The Sponsors are:
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED (a wholly-owned subsidiary of
Merrill Lynch & Co., Inc.)
P.O. Box 9051,
Princeton, NJ 08543-9051

SALOMON SMITH BARNEY INC. (an indirectly wholly-owned subsidiary of Citigroup
Inc.)
388 Greenwich Street--23rd Floor,
New York, NY 10013
DEAN WITTER REYNOLDS INC. (a principal operating subsidiary of Morgan Stanley
Dean Witter & Co.)

One New York Plaza
New York, NY 10292
PAINEWEBBER INCORPORATED (a wholly-owned subsidiary of PaineWebber Group Inc.)
1285 Avenue of the Americas,
New York, NY 10019

Each Sponsor is a Delaware corporation and it, or its predecessor, has acted as
sponsor to many unit investment trusts. As a registered broker-dealer each
Sponsor buys and sells securities (including investment company shares) for
others (including investment companies) and participates as an underwriter in
various selling groups.

TRUSTEE

The Bank of New York,101 Barclay Street-- 17W, New York, New York 10268, is the
Trustee. It is supervised by the Federal Deposit Insurance Corporation, the
Board of Governors of the Federal Reserve System and New York State banking
authorities.

UNDERWRITERS' AND SPONSORS' PROFITS

Underwriters receive sales charges when they sell units. The Sponsors also
realized a profit or loss on the initial deposit of the securities. Any

                                       10
<PAGE>
cash made available by you to the Sponsors before the settlement date for those
units may be used in the Sponsors' businesses to the extent permitted by federal
law and may benefit the Sponsors.

In maintaining a secondary market, the Sponsors will also realize profits or
sustain losses in the amount of any difference between the prices at which they
buy units and the prices at which they resell or redeem them.

PUBLIC DISTRIBUTION

The Sponsors do not intend to qualify units for sale in any foreign countries.
This prospectus does not constitute an offer to sell units in any country where
units cannot lawfully be sold.

CODE OF ETHICS

Merrill Lynch, as agent for the Sponsors, has adopted a code of ethics requiring
preclearance and reporting of personal securities transactions by its employees
with access to information on portfolio transactions. The goal of the code is to
prevent fraud, deception or misconduct against the Fund and to provide
reasonable standards of conduct.

YEAR 2000 ISSUES

Many computer systems were designed in such a way that they may be unable to
distinguish between the year 2000 and the year 1900 (commonly known as the 'Year
2000 Problem'). We do not expect that the computer system changes necessary to
prepare for the Year 2000 will cause any major operational difficulties for the
Fund. The Year 2000 Problem may adversely affect the issuers of the securities
contained in the Portfolio, but we cannot predict whether any impact will be
material to the Portfolio as a whole.

TAXES

The following summary describes some of the important income tax consequences of
holding units. It assumes that you are not a dealer, financial institution,
insurance company or other investor with special circumstances. You should
consult your own tax adviser about your particular circumstances.

The Sponsors believe that individual investors will not be subject to any state
or local personal income taxes on interest received by the Fund. However, you
may be subject to state and local taxes on capital gains (or 'market discount'),
and possibly other state and local taxes on your units. Also, you probably will
not be entitled to a deduction for state and local tax purposes for your share
of fees and expenses paid by the Fund, for any amortized 'bond premium' or for
any interest on money borrowed to purchase your units. You should consult your
tax adviser in this regard.

In the opinion of our counsel, under existing law:

GENERAL TREATMENT OF THE FUND AND YOUR INVESTMENT

The Fund will not be taxed as a corporation for federal income tax purposes, and
you
will be considered to own directly your share of each security in the Fund.

INCOME OR LOSS UPON DISPOSITION

When all or part of your share of a security is disposed of (for example, when
the Fund sells,

                                       11
<PAGE>
exchanges or redeems a security or when you sell or exchange your units), you
will generally recognize capital gain or loss. Your gain, however, will
generally be ordinary income to the extent of any accrued 'market discount'.
Generally you will have market discount to the extent that your basis in a
security when you purchase a unit is less than its stated redemption price at
maturity (or, if it is an original issue discount security, the issue price
increased by original issue discount that has accrued on the security before
your purchase). You should consult your tax adviser in this regard.

If your net long-term capital gains exceed your net short-term capital losses,
the excess may be subject to tax at a lower rate than ordinary income. Any
capital gain from the Fund will be long-term if you are considered to have held
your investment on each security for more than one year and short-term if you
held it for one year or less. Because the deductibility of capital losses is
subject to limitations, you may not be able to deduct all of your capital
losses. You should consult your tax advisor in this regard.

YOUR BASIS IN THE SECURITIES

Your aggregate basis in the securities will be equal to the cost of your units,
including any sales charges and the organizational expenses you pay, adjusted to
reflect any accruals of 'original issue discount,' 'acquisition premium' and
'bond premium'. You should consult your tax adviser in this regard.

EXPENSES

If you are an individual who itemizes deductions, you may deduct your share of
Fund expenses, but only to the extent that such amount, together with your other
miscellaneous deductions, exceeds 2% of your adjusted gross income. Your ability
to deduct Fund expenses will be limited further if your adjusted gross income
exceeds a specified amount (for 1999, $126,600 or $63,300 for a married person
filing separately).

FOREIGN INVESTORS

If you are a foreign investor and you are not engaged in a U.S. trade or
business, you generally will not be subject to U.S. federal income tax,
including withholding tax, on the interest or gain on a security issued after
July 18, 1984 if you meet certain requirements, including the certification of
foreign status and other matters. You should consult your tax adviser about the
possible application of federal, state and local, and foreign taxes.

RETIREMENT PLANS

You may wish to purchase units for an Individual Retirement Account (IRA) or
other retirement plan. Generally, capital gains and income received in each of
these plans are exempt from such plans are generally treated as ordinary income
but may, in some cases, be eligible for tax-deferred rollover treatment. You
should consult your attorney or tax adviser about the specific tax rules
relating to these plans. These plans are offered by brokerage firms, including
the Sponsors of this Fund, and other financial institutions. Fees and charges
with respect to such plans may vary.

                                       12

SUPPLEMENTAL INFORMATION

You can receive at no cost supplemental information about the Fund by calling
the Trustee. The supplemental information includes more detailed risk disclosure
about the securities that may be in the Fund's portfolio and general information
about the structure and operation of the Fund. The supplemental information is
also available from the SEC.

REPORT OF INDEPENDENT ACCOUNTANTS


The Sponsors, Trustee and Holders
  of Defined Asset Funds - Government Securities Income Fund,
  Monthly Payment U.S. Treasury Series - 3:


We have audited the accompanying statement of condition of Defined
Asset Funds - Government Securities Income Fund, Monthly Payment U.S.
Treasury Series - 3, including the portfolio, as of May 31, 1999 and
the related statements of operations and of changes in net assets for
the years ended May 31, 1999, 1998 and 1997. These financial
statements are the responsibility of the Trustee. Our responsibility
is to express an opinion on these financial statements based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the
financial statements. Securities owned at May 31, 1999, as shown in
such portfolio, were confirmed to us by The Bank of New York, the
Trustee. An audit also includes assessing the accounting principles
used and significant estimates made by the Trustee, as well as
evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Defined
Asset Funds - Government Securities Income Fund, Monthly Payment U.S.
Treasury Series - 3 at May 31, 1999 and the results of its operations
and changes in its net assets for the above-stated years in conformity
with generally accepted accounting principles.

NOTES TO PORTFOLIO
AS OF MAY 31, 1999

   (1) The ratings of the bonds are by Standard & Poor's Ratings
       Group, or by Moody's Investors Service, Inc. if followed by
       "(m)", or by Fitch Investors Service, Inc. if followed by
       "(f)"; "NR" indicates that this bond is not currently rated by
       any of the above-mentioned rating services. These ratings have
       been furnished by the Evaluator but not confirmed with
       the rating agencies.

   (2) See Notes to Financial Statements.

   (3) Optional redemption provisions, which may be exercised in whole
       or in part, are initially at prices of par plus a premium, then
       subsequently at prices declining to par. Certain securities may
       provide for redemption at par prior or in addition to any
       optional or mandatory redemption dates or maturity, for
       example, through the operation of a maintenance and replacement
       fund, if proceeds are not able to be used as contemplated, the
       project is condemned or sold or the project is destroyed and
       insurance proceeds are used to redeem the securities. Many of
       the securities are also subject to mandatory sinking fund
       redemption commencing on dates which may be prior to the date
       on which securities may be optionally redeemed. Sinking fund
       redemptions are at par and redeem only part of the issue. Some
       of the securities have mandatory sinking funds which contain
       optional provisions permitting the issuer to increase the
       principal amount of securities called on a mandatory redemption
       date. The sinking fund redemptions with optional provisions
       may, and optional refunding redemptions generally will, occur
       at times when the redeemed securities have an offering side
       evaluation which represents a premium over par. To the extent
       that the securities were acquired at a price higher than the
       redemption price, this will represent a loss of capital when
       compared with the Public Offering Price of the Units when
       acquired. Distributions will generally be reduced by the amount
       of the income which would otherwise have been paid with respect
       to redeemed securities and there will be distributed to Holders
       any principal amount and premium received on such redemption
       after satisfying any redemption requests for Units received by
       the Fund. The estimated current return may be affected by
       redemptions.
