TO OUR SHAREHOLDERS

The Municipal Market Environment
During the six months ended July 31, 1998, long-term tax-exempt
revenue bond yields were little changed. Throughout the period, the
near absence of inflationary pressures continued to support low
interest rates. However, consistently strong domestic economic
growth has caused some investors to fear that the Federal Reserve
Board will be forced eventually to raise short-term interest rates.
Such action would be taken to ensure that the US economy's present
rate of growth would decelerate before any inflationary pressures
could develop. These concerns pushed bond yields modestly higher by
late April.

However, the weakening financial conditions in many Asian countries
subsequently calmed investor fears of Federal Reserve Board
intervention, and fixed-income prices again moved higher. Long-term
uninsured municipal bond yields, as measured by the Bond Buyer
Revenue Bond Index, rose less than 5 basis points (0.05%) to end the
July quarter at 5.36%. As in late 1997 and early 1998, US Treasury
bond yields benefited from a "flight to quality" as foreign
investors were drawn to the relative safe haven of US Government
securities. Long-term US Treasury bond yields declined approximately
10 basis points to end the July quarter at 5.71%.

Thus far in 1998, the municipal bond market has experienced
unexpectedly strong supply pressures. These supply pressures have
prevented tax-exempt bond yields from declining as much as US
Treasury bond yields. During the first six months of 1998, more than
$153 billion in new tax-exempt bonds were underwritten, an increase
of almost 50% compared to the same period a year ago. During the
quarter ended July 31, 1998, municipalities issued over $75 billion
in new securities, an increase of more than 35% compared to the same
three-month period in 1997. Additionally, corporate issuers have
also viewed current interest rate levels as an opportunity to issue
significant amounts of taxable securities. Thus far in 1998, over
$500 billion in investment-grade corporate bonds have been
underwritten, an increase of more than 70% compared to the same
period a year ago. This sizeable corporate bond issuance has tended
to both support generally higher fixed-income yields and reduce the
demand for tax-exempt bonds.

However, the recent pace of new municipal bond issuance is unlikely
to be maintained. Continued increases in bond issuance will require
lower and lower tax-exempt bond yields to generate the economic
savings necessary for additional municipal bond refinancings.
Preliminary estimates for 1998 total municipal bond issuance are in
the $200 billion--$225 billion range. These estimates suggest that
recent supply pressures are likely to abate later in the year.
Earlier this year, municipal bond investors received approximately
$30 billion in coupon payments, bond maturities and proceeds from
early redemptions. The demand generated by these assets has helped
to offset the increase in supply seen thus far in 1998.

The continued impact of the Asian financial crisis on the US
domestic economy's future growth remains unclear. Current Asian
economic conditions continue to reflect ongoing weakness. Recent
trade data indicated that reduced US exports to these countries may
have lowered US economic growth by as much as 2% in the first
quarter of 1998. Since further trade deterioration is possible in
the coming months, we do not believe that the Federal Reserve Board
will be willing to raise interest rates, barring a dramatic and
unexpected resurgence of domestic inflation.

These factors suggest that over the near term, interest rates are
unlikely to rise by any appreciable amount. Recent supply pressures
have caused municipal bond yield ratios to rise relative to US
Treasury bond yields. At July 31, 1998, long-term tax-exempt bond
yields were at attractive yield ratios relative to US Treasury
securities of comparable maturities (over 90%), well in excess of
their expected range of 85%--88%. Tax-exempt bond yield ratios
rarely exceeded 90% in the 1980s and 1990s. Previous instances have
usually been associated with potential changes in the Federal tax
code that would have adversely affected the tax-favored status of
municipal bonds. The present situation has developed largely because
of a temporary supply imbalance. These imbalances should soon be
corrected as tax-exempt bond issuance slows from its current rapid
pace later this year. Any further pressure on the municipal market
may well represent a very attractive investment opportunity.

Portfolio Strategy
During the six-month period ended July 31, 1998, our investment
outlook for Merrill Lynch Maryland Municipal Bond Fund was basically
constructive. The deterioration in the Asian economies helped keep
interest rates low, even in the face of strong domestic economic
growth. This combination of strong growth and low inflation kept
bond yields within a rather narrow trading range over the past six
months.

Issuance of new Maryland tax-exempt municipal bonds was just over
$2.2 million during the six-month period ended July 31, 1998. This
represents an increase of more than 40% compared to the same six-
month period a year ago. Additionally, the majority of new issuance
in Maryland was dominated by current coupons and lesser call
protection. We do not view such securities as attractive additions
to the Fund's portfolio.

Looking ahead, we expect to continue to maintain our fully invested
position and our constructive portfolio strategy to seek to benefit
from a lower interest rate environment. However, anticipated lack of
new issuance in Maryland may curtail our ability to execute this
strategy.


Fiscal Year in Review
During the fiscal year ended July 31, 1998, total municipal issuance
increased by more than 40% compared to the same period last year,
while Maryland municipal issuance increased by more than 30% over
the same period. Both the tax-exempt and US Treasury markets
experienced a decline in yields, although the greater increase in
tax-exempt issuance resulted in municipal performance lagging that
of US Treasury securities.

Given the narrow trading range of the municipal bond market, we
maintained a slightly defensive strategy going into the second half
of 1997. We believed that economic growth would resurge and the
Federal Reserve Board would raise interest rates in order to keep
inflation under control. However, in late October 1997, the Asian
equity market turmoil created an increased demand for US Treasury
securities, causing a rally in the bond market. In response to the
Asian economic crisis and the continued domestic low inflation
environment, we shifted the Fund to a more aggressive position by
early November 1997. We remained constructive through July 31, 1998,
participating in the continued bond market rally, which brought
interest rates to their recent historic lows.

Throughout the fiscal year ended July 31, 1998, we maintained the
Fund's fully invested position. These strategies produced total
returns of +6.46%, +5.92%, +5.70% and +6.35% for the Fund's Class A,
Class B, Class C and Class D Shares, respectively, for the year
ended July 31, 1998. This compares to the Lipper Analytical
Services, Inc. average total return of +5.18% for similar Maryland
tax-exempt funds during the same 12-month period.

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

Sincerely,

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Recent Performance
Results" and "Average Annual Total Return" tables assume
reinvestment of all dividends and capital gains distributions at net
asset value on the payable date. Investment return and principal
value of shares will fluctuate so that shares, when redeemed, may be
worth more or less than their original cost. Dividends paid to each
class of shares will vary because of the different levels of account
maintenance, distribution and transfer agency fees applicable to
each class, which are deducted from the income available to be paid
to shareholders.

Merrill Lynch Maryland Municipal Bond Fund

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Maryland 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. The Fund offers
four classes of shares under the Merrill Lynch Select Pricing SM
System. Shares of Class A and Class D are sold with a front-end
sales charge. Shares of Class B and Class C may be subject to a
contingent deferred sales charge. All classes of shares have
identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class B, Class C and Class D
Shares bear certain expenses related to the account maintenance of
such shares, and Class B and Class C Shares also bear certain
expenses related to the distribution of such shares. Each class has
exclusive voting rights with respect to matters relating to its
account maintenance and 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.
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) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial 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.

(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 period not exceeding five years. 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"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner. The Fund has also entered into a Distribution
Agreement and Distribution Plans with Merrill Lynch Funds
Distributor ("MLFD" or "Distributor"), a division of Princeton Funds
Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary of
Merrill Lynch Group, Inc.

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.

For the year ended July 31, 1998, FAM earned fees of $147,950, of
which $120,685 was voluntarily waived. FAM also reimbursed the Fund
additional expenses of $9,100.

Pursuant to the Distribution Plans adopted by the Fund in accordance
with Rule 12b-1 under the Investment Company Act of 1940, the Fund
pays the Distributor ongoing account maintenance and distribution
fees. The fees are accrued daily and paid monthly at annual rates
based upon the average daily net assets of the shares as follows:


                                     Account       Distribution
                                 Maintenance Fee        Fee

Class B                                0.25%            0.25%
Class C                                0.25%            0.35%
Class D                                0.10%             --


Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Inc. ("MLPF&S"), a subsidiary of ML & Co.,
also provides account maintenance and distribution services to the
Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
shareholders.

For the year ended July 31, 1998, MLFD earned underwriting discounts
and MLPF&S earned dealer concessions on sales of the Fund's Class A
and Class D Shares as follows:


                          MLFD        MLPF&S

Class D                   $919        $7,376


For the year ended July 31, 1998, MLPF&S received contingent
deferred sales charges of $41,916 and $150 relating to transactions
in Class B and Class C Shares, respectively.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of
ML & Co., is the Fund's transfer agent.

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, PSI, FDS, PFD, and/or ML & Co.
