Merrill Lynch Colorado Municipal Bond Fund          January 31, 1998

TO OUR SHAREHOLDERS

The Municipal Market Environment
During the six months ended January 31, 1998, long-term bond yields 
declined to recent historic lows. Prior to late October, the ongoing 
positive combination of moderate economic growth and low inflation had 
allowed interest rates to gradually move lower. During the last three 
months, however, the decline in interest rates was driven more by the 
continued turmoil in Asian equity markets than by fundamental 
concerns. A significant "flight to quality" has benefited the US 
Treasury bond market, particularly longer-maturity US Treasury bonds, 
as foreign investors have sought safe haven in the relative stability 
of US financial markets. Over the six months ended January 31, 1998, 
US Treasury bond yields declined approximately 50 basis points (0.50%) 
to 5.81%. 

Without the ability to benefit from the tax advantage inherent in 
municipal bonds, foreign investors have not participated in the tax-
exempt market. Consequently, municipal bond yields have not declined 
dramatically as have taxable US Treasury securities. Long-term 
municipal revenue bond yields, as measured by the Bond Buyer Revenue 
Index, declined only 15 basis points to end the six-month period ended 
January 31, 1998 at 5.33%. Nevertheless, tax-exempt bond yields have 
not reached these levels since the mid-1970s.

The increase in new municipal bond issuance over the past six months 
has also prevented the tax-exempt bond market from more closely 
mirroring the yield declines exhibited by its taxable counterpart. 
During the last six months, over $120 billion in new long-term 
municipal bonds were underwritten, an increase of over 30% compared to 
the same six-month period one year ago. As interest rates have 
continued to decline in recent months, new tax-exempt bond issuance 
has remained strong. Over $60 million in new long-term municipal 
securities were issued during the last three months, an increase of 
over 20% compared to the same three-month period ended January 31, 
1997. During the past month, over $16 billion in new long-term 
municipal securities were underwritten, representing an increase of 
over 40% compared to the January 1997 level.

In our opinion, the recent correction in world equity markets has 
enhanced the near-term prospects for continued low, if not declining, 
interest rates in the United States. It is likely that the recent 
correction will result in slower US domestic growth in the coming 
months. This decline should be generated in part by reduced US export 
growth. Additionally, some decline in consumer spending can also be 
expected because of reduced consumer confidence. Perhaps more 
importantly, it is likely that, barring a dramatic and unexpected 
resurgence in domestic growth, the Federal Reserve Board will be 
unwilling to raise interest rates until the full impact of the equity 
market's corrections can be established.

All of these factors suggest that over the near term, interest rates, 
including tax-exempt bond yields, are unlikely to rise by any 
appreciable amount. It is probable that municipal bond yields will 
remain under some relative pressure because of continued strong new-
issue supply. However, the recent pace of municipal bond issuance is 
likely to be unsustainable. 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 of 1998 total municipal bond issuance are 
presently in the $195 billion -- $220 billion range. These estimates 
suggest that recent supply pressures are likely to abate somewhat next 
year, or at least exert only minimal technical pressure during 1998. 
Additionally, municipal bond investors received approximately $23 
billion in January coupon payments, bond maturities and proceeds from 
early redemptions, which should serve to intensify investor demand in 
the near future. With tax-exempt bond yields at already attractive 
yield ratios relative to US Treasury bonds (approximately 90% at the 
end of December 1997), any further pressure on the municipal market 
may well represent an attractive investment opportunity.

Portfolio Strategy
During the six months ended January 31, 1998, our portfolio strategy 
was a continuation of our positive outlook on the market. Since the 
spring of 1997, the Fund has been fully invested in quality long-
duration municipal bonds, allowing it to participate in the powerful 
bond market appreciation. As mentioned in our last report to 
shareholders, we stated that at that time we expected to restructure 
the Fund to become slightly more defensive as interest rates continued 
to decline. However, we chose not to do this because of the 
significant turmoil caused by the Asian financial crisis. As world 
markets experienced periods of volatility, investors sought the safe 
haven of US Treasury bonds which, in turn, benefited fixed-income 
securities.

The structure of the Fund remained focused on quality municipal bonds. 
As of January 31, 1998, 86.3% of the Fund's portfolio was rated A or 
better.  Looking ahead, we anticipate keeping our present portfolio 
structure in place until Asia stabilizes or the US economy shows signs 
of pushing inflation higher.

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

PERFORMANCE DATA

About Fund Performance

Investors are able to purchase shares of the Fund through the Merrill 
Lynch Select PricingSM System, which offers four pricing alternatives:

[bullet] Class A Shares incur a maximum initial sales charge (front-
end load) of 4% and bear no ongoing distribution or account 
maintenance fees. Class A Shares are available only to eligible 
investors.

[bullet] Class B Shares are subject to a maximum contingent deferred 
sales charge of 4% if redeemed during the first year, decreasing 1% 
each year thereafter to 0% after the fourth year. In addition, Class B 
Shares are subject to a distribution fee of 0.25% and an account 
maintenance fee of 0.25%. These shares automatically convert to 
Class D Shares after approximately 10 years. (There is no initial 
sales charge for automatic share conversions.)

[bullet] Class C Shares are subject to a distribution fee of 0.35% and 
an account maintenance fee of 0.25%. In addition, Class C Shares are 
subject to a 1% contingent deferred sales charge if redeemed within 
one year of purchase.

[bullet] Class D Shares incur a maximum initial sales charge of 4% and 
an account maintenance fee of 0.10% (but no distribution fee).

None of the past results shown should be considered a representation 
of future performance. Figures shown in the "Average Annual Total 
Return" tables as well as the total returns and cumulative total 
returns in the "Performance Summary" 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 Colorado Municipal Bond Fund          January 31, 1998

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Colorado 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. These 
unaudited financial statements reflect all adjustments which are, in 
the opinion of management, necessary to a fair statement of the 
results for the interim period presented. All such adjustments are of 
a normal recurring nature. The Fund offers four classes of shares 
under the Merrill Lynch Select PricingSM 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.

[bullet] 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 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"). 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, Inc. ("MLFD" 
or "Distributor"), 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 six months ended January 31, 1998, FAM earned fees of $84,119, 
of which $53,530 was voluntarily waived.

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
                            Maintenance            Distribution 
                                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 six months ended January 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 A                        $50                  $266
Class D                        $28                  $162

For the six months ended January 31, 1998, MLPF&S received contingent 
deferred sales charges of $14,322 relating to transactions in Class B 
Shares.

Merrill Lynch Financial Data Services, Inc. ("MLFDS"), 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, MLFDS, MLFD, and/or ML & Co.
