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.

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
relationship 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.

Fiscal Year in Review
Merrill Lynch Oregon Municipal Bond Fund commenced operations on
August 27, 1993. Since that time, the Fund has grown from $17.8
million to $32.7 million at July 31,1994, representing an 83.7%
growth rate. The municipal bond market rallied since the Fund's
inception until the middle of October 1993, but has been on a
downward trend since. The yield on the Bond Buyer Revenue Bond Index
has increased over 90 basis points since the Fund's inception.

Our initial strategy was to invest in long-term municipal bonds. At
the time, the interest rate outlook was constructive for the bond
market. Therefore, we invested in discount bonds which perform well
in an up market. However, strong fourth quarter 1993 economic growth
data forced the Federal Reserve Board to implement a more
restrictive monetary policy beginning in February of this year,
causing taxable long-term interest rates to increase by more than
100 basis points. As a result, the Fund's Class A and Class B Shares
underperformed relative to the municipal market as a whole.

Recently, we reduced the Fund's exposure to discount bonds and
purchased higher coupon bonds in an effort to increase the Fund's
total returns. Looking ahead, we are constructive on municipal bonds
because of the predicted slowdown of the US economy during the
second half of 1994 and the reduction of new-issue supply of
municipal bonds in 1994 compared to 1993.

We appreciate your ongoing interest in Merrill Lynch Oregon
Municipal Bond Fund, and we look forward to serving your investment
needs and objectives in the months and years to come.

Sincerely,

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
Merrill Lynch Oregon Municipal Bond Fund (the "Fund") is part of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust"). The
Fund is registered under the Investment Company Act of 1940 as a non-
diversified, open-end management investment company. Prior to
commencement of operations on August 27, 1993, the Fund had no
operations other than those relating to organizational matters and
the issuance of 5,000 Class A Shares of beneficial interest and
5,000 Class B Shares of beneficial interest of the Fund to Fund
Asset Management, L.P. ("FAM") for $100,000. The Fund offers both
Class A and Class B Shares. Class A Shares are sold with a front-end
sales charge. Class B Shares may be subject to a contingent deferred
sales charge. Both classes of shares have 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. Securities 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.

(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
securities 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 deposits and maintains as collateral such initial
margin as required by the exchange on which the transaction is
effected. Pursuant to the 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.

NOTES TO FINANCIAL STATEMENTS (concluded)

(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 beginning with commencement of
operations. 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. Distributions in excess
of realized capital gains are due primarily to differing tax
treatments for futures transactions and post October losses.

2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with 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 &

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
