TO OUR SHAREHOLDERS


The expectation of increasing inflationary pressures and higher
interest rates initially heightened investor concerns and increased
financial market volatility during the July quarter. However, as the
quarter progressed, it was the weakness of the US dollar in foreign
exchange markets that dominated the financial news and prolonged
stock and bond market declines. Although the US dollar had
strengthened slightly by July quarter-end, which may have improved
investor confidence in the stock and bond markets, the possibility
of continued tightening by the Federal Reserve Board resurfaced
following Chairman Alan Greenspan's recent congressional testimony.
Nevertheless, as the quarter drew to a close, a lower-than-expected
rate of growth reported for the US economy during the second
calendar quarter allayed investor concerns and led to stock and bond
market rallies.
<PAGE>
During the July quarter, the US dollar's weakness relative to other
major currencies reflected the deteriorating US trade deficit and
widening net long-term capital outflows. In 1993, an expanding US
economy and recession in other industrial countries led to a higher
level of imports and weaker export growth, widening the US trade
deficit further. In addition, global investors favored non-US dollar
denominated assets throughout 1993, which has further depressed the
dollar's value. This trend is not improving significantly thus far
in 1994 since foreign inflows into US capital markets continue to
decline, although US investors are investing outside of the United
States to a lesser degree.

Over the longer term, if the economies of the United States' major
trading partners expand (improving the prospects for US export
growth), the outlook for the US dollar is likely to improve. In the
near term, central banks have attempted to reverse the dollar's
decline through currency market intervention. These efforts have met
with limited success thus far, giving rise to the concern that the
Federal Reserve Board will be forced to continue to raise short-term
interest rates to attract investment capital back to the United
States and bolster the dollar's value. However, further interest
rate increases may jeopardize the US economic expansion. Despite
evidence of a moderating trend in the US economy, Federal Reserve
Board Chairman Alan Greenspan indicated in his July Humphrey-Hawkins
testimony that the central bank would prefer to err on the side of
too much monetary tightening rather than too little. In the weeks
ahead, investors will continue to assess economic data and
inflationary trends as they focus on the US dollar in order to gauge
whether further increases in short-term interest rates are imminent.
Continued indications of moderate and sustainable levels of economic
growth would be positive for the US capital markets.

The Municipal Market
Long-term tax-exempt bond yields ended the July quarter essentially
unchanged. The Bond Buyer Revenue Bond Index rose five basis points
(0.05%) to 6.47%. The Index, however, failed to capture the dramatic
bond rally on July 29, 1994, when municipal bond yields had their
largest one-day decline thus far this year. Responding to reports of
a continued mild inflationary outlook and a potentially weakening
economy, municipal bond yields declined by approximately 10 basis
points. US Treasury bonds displayed a similar pattern over the last
three months, ending with an equally dramatic rally on July 29,
1994. Long-term US Treasury bonds ended the quarter yielding
approximately 7.40%.

The tax-exempt bond market has continued to be very volatile with
yields fluctuating by as much as 15 basis points from week to week.
This continued volatility is largely a reflection of the same lack
of conviction regarding the near-term direction of interest rates
that has prevailed for much of 1994. Throughout this past quarter,
the municipal bond market had been unable to maintain a consensus
regarding either the potential strength of the current economic
recovery or the resultant response by the Federal Reserve Board.
However, a number of economic indicators released in late July began
to suggest that the robust pace of recent economic growth was
slowing. This promoted a more positive market environment,
culminating in the market rally on July 29.

The municipal bond market's technical position has remained
supportive. Approximately $40 billion in long-term securities were
issued during the three months ended July 31, 1994. This represents
a decline of over 50% versus the July quarter from the previous
year. As discussed in earlier reports, this reduction in new-issue
supply has minimized the selling pressure by larger institutional
investors who fear being unable to purchase sizable amounts of
securities in the future. Such a significant decline in issuance
would normally be expected to trigger a decline in yields as
investors chase a commodity in scarce supply. Investor demand,
however, has also diminished somewhat in recent months as net flows
into long-term municipal bond funds have dramatically slowed or, in
some instances, reversed. Consequently, the supply/demand relation-
ship within the municipal bond market has remained in balance,
promoting the overall stability in yield levels seen in the past
months.

With after-tax equivalents in excess of 10%, long-term tax-exempt
bonds continue to represent considerable value relative to other
investment alternatives. We continue to anticipate that municipal
bond yields will decline further in late 1994 and into 1995. The
economic impact of the significant interest rate increases
experienced since early February have yet to be totally realized.
The resultant drag on the economy should provide the foundation for
further interest rate declines. Under such a scenario, current tax-
exempt bond yields may prove to represent considerable value.
<PAGE>
Fiscal Year in Review
Merrill Lynch Arizona Municipal Bond Fund was consistently
positioned to provide as generous as possible a current return to
its shareholders while concentrating the majority of its assets in
higher-rated Arizona credits. Throughout the past fiscal year, we
have addressed these goals by maintaining a minimal cash reserve
position, ranging from 2% of net assets during more aggressive
periods to a high of approximately 10% during times when interest
rate volatility called for a more guarded approach. The level of
coupon the Fund utilizes is above industry average, given our view
that in periods of interest rate uncertainty the cushioned effect
these higher-coupon issues provide is better suited to protecting
the Fund's overall asset value. This structure has allowed the Fund
to perform on a total return basis above the general Arizona
municipal bond marketplace. Contributing to this built-in cushioning
effect is a relatively high portion of the Fund's assets in
prerefunded securities. These holdings currently provide the Fund
with a generous level of current return with the additional benefit
of the market sensitivity of a shorter maturity position. As time
passes and the call provisions for these securities near, we expect
to sell these prerefunded bonds before the premium they command
begins to run off. We will continue to manage the Fund with a focus
toward a point where more confidence for a general stabilization in
interest rates can be forecast. The technical background for the
Arizona municipal bond market is exceedingly positive with limited
issuance scheduled over the next six months. Therefore, as signs of
economic slowing materialize, which could encourage interest rate
stability, we will look toward becoming more aggressive to take
advantage of any new leg in an upturn for fixed-income security
prices.

identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class B Shares bear certain
expenses related to the distribution of such shares and have
exclusive voting rights with respect to matters relating to such
distribution expenditures. The following is a summary of significant
accounting policies followed by the Fund.

(a)Valuation of investments--Municipal bonds and other portfolio
securities in which the Fund invests are traded primarily in the
over-the-counter municipal bond and money markets and are valued at
the last available bid price in the over-the-counter market or on
the basis of yield equivalents as obtained from one or more dealers
that make markets in the securities. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their
settlement prices as of the close of such exchanges. Short-term
investments with remaining maturities of sixty days or less are
valued at amortized cost, which approximates market value. Options,
which are traded on exchanges, are valued at their last sale price
as of the close of such exchanges or, lacking any sales, at the last
available bid price. Securities and assets for which market
quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of
Trustees of the Trust, including valuations furnished by a pricing
service retained by the Trust, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Trust under the general
supervision of the Trustees.
<PAGE>
(b)Financial futures contracts--The Fund may purchase or sell
interest rate futures contracts and options on such futures
contracts for the purpose of hedging the market risk on existing or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at
a specific price or yield. Upon entering into a contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal
to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund
as unrealized gains or losses. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the
time it was closed.

(c)Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d)Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e)Deferred organization expenses and prepaid registration fees--
Deferred organization expenses are charged to expense on a straight-
line basis over a five-year period. Prepaid registration fees are
charged to expense as the related shares are issued.

(f)Dividends and distributions--Dividends from net investment income
are declared daily and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). Effective January 1, 1994, the
investment advisory business of FAM was reorganized from a
corporation to a limited partnership. Both prior to and after the
reorganization, ultimate control of FAM was vested with Merrill
Lynch & Co., Inc. ("ML & Co."). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of ML & Co. The limited partners are ML & Co. and Fund
Asset Management, Inc. ("FAMI"), which is also an indirect wholly-
owned subsidiary of ML & Co. The Fund has also entered into
Distribution Agreements and a Distribution Plan with Merrill Lynch
Funds Distributor, Inc. ("MLFD" or "Distributor"), a wholly-owned
subsidiary of Merrill Lynch Investment Management, Inc. ("MLIM"),
which is also an indirect wholly-owned subsidiary of ML & Co.
<PAGE>
FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee based upon the average daily
value of the Fund's net assets at the following annual rates: 0.55%
of the Fund's average daily net assets not exceeding $500 million;
0.525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and 0.50% of average daily net assets in
excess of $1 billion. The Investment Advisory Agreement obligates
FAM to reimburse the Fund to the extent the Fund's expenses
(excluding interest, taxes, distribution fees, brokerage fees and
commissions, and extraordinary items) exceed 2.5% of the Fund's
first $30 million of average daily net assets, 2.0% of the next $70
million of average daily net assets and 1.5% of the average daily
net assets in excess thereof. FAM's obligation to reimburse the Fund
is limited to the amount of the management fee. No fee payment will
be made during any fiscal year which will cause such expenses to
exceed expense limitation at the time of such payment. For the year
ended July 31, 1994, FAM had management fees of $566,701, of which
$239,468 was voluntarily waived.

The Fund has adopted a Plan of Distribution (the "Plan") in
accordance with Rule 12b-1 under the Investment Company Act of 1940
pursuant to which the Fund pays the Distributor ongoing account
maintenance and distribution fees relating to Class B Shares which
are accrued daily and paid monthly at the annual rate of 0.25% and
0.25%, respectively, of the average daily net assets of the Class B
Shares of the Fund. Pursuant to a sub-agreement with the
Distributor, Merrill Lynch also provides account maintenance and
distribution services to the Fund. The ongoing account maintenance
fee compensates the Distributor and Merrill Lynch for providing account
maintenance services to Class B shareholders. As authorized by the
plan, the Distributor has entered into an agreement with Merrill
Lynch, Pierce, Fenner & Smith Inc. ("MLPF&S"), an affiliate of ML &
Co., which provides for the compensation of MLPF&S for providing
distribution-related services to the Fund.

For the year ended July 31, 1994, MLFD earned underwriting discounts
of $6,133, and MLPF&S earned dealer concessions of $76,301 on sales
of the Fund's Class A Shares.

MLPF&S also received contingent deferred sales charges of $217,476
relating to Class B Share transactions during the period.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of
ML & Co., is the Fund's transfer agent.
<PAGE>
Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or
directors of FAM, FAMI, PSI, MLFD, MLIM, FDS, MLPF&S, and/or ML &
Co.

3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the period ended July 31, 1994 were $58,315,671 and $51,271,681,
respectively.
