DEAR SHAREHOLDER

For the year ended August 31, 1999, Merrill Lynch High Income
Municipal Bond Fund, Inc. earned $0.553 per share income dividends,
representing a net annualized yield of 5.40%, based on a month-end
per share net asset value of $10.24. During the same period, the
Fund's total investment return was -3.16%, based on a change in per
share net asset value from $11.46 to $10.24, and assuming
reinvestment of $0.616 per share ordinary income dividends and
$0.263 per share capital gains distributions.

For the three-month period ended August 31, 1999, the Fund's total
investment return was -3.43%, based on a change in per share net
asset value from $10.75 to $10.24, and assuming reinvestment of
$0.140 per share income dividends.


The Municipal Market Environment
During the three months ended August 31, 1999, long-term bond yields
rose significantly. Steady US economic growth combined with
improvement in foreign economies and inflation concerns put upward
pressure on bond yields throughout the period. Continued strong US
employment growth, particularly the decline in the US unemployment
rate to 4.2% in early June, was among the reasons the Federal
Reserve Board cited for raising short-term interest rates in late
June. US Treasury bond yields reacted by climbing above 6.25% by mid-
August before improving somewhat to 6.06% by August 31, 1999. During
the last three months, yields on long-term US Treasury securities
increased approximately 25 basis points (0.25%).

Long-term tax-exempt bond yields also rose during the last three
months. Until early May, the municipal bond market had been able to
withstand much of the upward pressure on bond yields. However,
investor concerns regarding ongoing US economic strength and the
fear of additional moves by the Federal Reserve Board eventually
pushed municipal bond yields higher. During the period, yields on
long-term tax-exempt revenue bonds rose more than 40 basis points to
5.83%, as measured by the Bond Buyer Revenue Bond Index.

While the tax-exempt market has slightly underperformed its taxable
counterpart in recent months, technical conditions are helping to
support municipal bond prices. During the last six months, more than
$115 billion in long-term municipal bonds was underwritten, a
decrease of more than 20% compared to the same period a year ago.
During the past three months, almost $60 billion in municipal bonds
was underwritten. This quarterly issuance represents a decline of
approximately 20% compared to the same three-month period in 1998.

Recently, the supply of new municipal bonds slowed even further.
Total issuance in August 1999 of $14 billion was nearly 40% lower
than August 1998 levels. Additionally, in June and July, investors
received more than $40 billion in coupon income and proceeds from
bond maturities and early bond redemptions. These proceeds have
generated significant retail investor interest, easily absorbing the
recent diminished supply.

The recent relative underperformance of the municipal bond market
has generated very attractive tax-exempt bond yield ratios, similar
to those that were available at the end of 1998. In December 1998,
long-term, uninsured municipal bond yields were higher than those of
their taxable counterparts. Historically, long-term tax-exempt bond
yields have been approximately 82%--85% of long-term US Treasury
bond yields. Municipal bond yields rose at a faster rate in recent
months than US Treasury bond yields, causing the yield ratio to
increase. At May 31, 1999, long-term municipal bond yields were
approximately 92% of their taxable counterparts. At August 31, 1999,
long-term uninsured tax-exempt bond yields were approximately 96% of
US Treasury bonds. Current ratios, while lower than those available
at the end of 1998, still represent historically attractive levels.

Looking ahead, it appears to us that long-term municipal bond yields
will trade in a relatively tight range near current levels. Strong
US economic performance is being balanced by nearly negligible
inflation readings, as well as improvements in productivity in both
manufacturing and service industries. We believe that future moves
by the Federal Reserve Board have largely been discounted by bond
investors and are to a great extent reflected in present bond
yields.

Any improvement in bond prices is likely to be contingent upon
weakening in both US employment growth and consumer spending. The
100 basis point rise in US Treasury bond yields seen thus far this
year is likely to negatively affect US economic growth. The US
housing market will be among the first sectors likely to be
affected, as some declines have already been evidenced because of
higher mortgage rates. We believe it is also unrealistic to expect
double-digit returns in US equity markets to continue indefinitely.
Much of the US consumer's wealth is tied to recent stock market
appreciation. Any slowing in these incredible growth rates is likely
to reduce consumer spending. We believe that these factors suggest
that the worst of the recent increase in bond yields has passed and
stable, if not slightly improving, bond prices may be expected.

Portfolio Strategy
Credit spreads within the municipal market reverted to their
historically narrow levels during the past 12 months since the
financial markets have stabilized. Corporate-related tax-exempt debt
benefited the most as a rebound in commodity prices and robust
economic growth contributed to growing optimism over earnings
prospects. The Fund remains heavily weighted in this sector because
of the diversification opportunities offered by corporate debt. In
addition, the ready availability of adequate and continuous
disclosure substantially enhances liquidity within this sector. For
these reasons, we expect the debt of corporations as well as of
investor-owned utilities to remain a significant portion of the
Fund's portfolio for the near term. Issuance in the corporate-backed
sector remains thin, mirroring the lack of supply in the overall
municipal market and exacerbating an already tight technical
situation.

In contrast to the corporate sector, healthcare-related debt has
undergone appreciable deterioration in credit fundamentals and
market liquidity. The financials of many nonprofit hospitals have
weakened in recent quarters as they struggle to cope with rising
costs, reduced reimbursement rates because of the Balanced Budget
Act and increased competition. We have maintained limited exposure
in this sector and, while we remain circumspect given the strained
environment, credit spreads have widened out to the point where much
of the bad news appears to have been discounted. As a result, we
have begun to establish small positions in credits that we believe
have been unnecessarily punished by the market and therefore
represent good value.

Extending the portfolio's average call protection remained a
strategic focus both throughout the Fund's fiscal year and, in
particular, the quarter ended August 31, 1999. Municipal securities
are typically issued with optional call features giving the issuer
the right to redeem outstanding debt prior to maturity. This usually
occurs at an inopportune time from the investor's perspective, as
interest rates are likely to be lower. In light of this ongoing
reinvestment risk, we have maintained a proactively managed call
exposure in an effort to reduce the impact on the portfolio's
overall income stream and, ultimately, seek to generate a more
stable dividend for shareholders over the long term.

Our investment strategy has become more flexible in order to allow
for more short-term trading opportunities. As a result, we have
placed a greater emphasis on liquidity and, consequently, our focus
has shifted toward larger and more widely distributed issues.
Smaller issues are typically closely held by a handful of investors.
They tend to trade infrequently and are subject to higher
transaction costs, making them unsuitable for our current investment
style. Our attempt to capitalize on short-term inefficiencies within
the tax-exempt high-yield arena will likely generate more turnover
than the portfolio has experienced in the past. However, we believe
the enhanced degree of liquidity should prove beneficial both in
terms of reducing individual credit risk as well as rendering the
portfolio more responsive to changes in our investment outlook.

Municipal Bond Fund, Inc., and we look forward to assisting you with

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch High Income Municipal Bond Fund, Inc. (the "Fund") is
registered under the Investment Company Act of 1940 as a
continuously offered, non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in
accordance with generally accepted accounting principles, which may
require the use of management accruals and estimates. 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. Options written
or purchased are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-
the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). 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 Directors of the Fund, including
valuations furnished by a pricing service retained by the Fund,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Fund under the general supervision of the Board of Directors.

(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.

* Options--The Fund is authorized to write covered call options and
purchase put and call options. When the Fund writes an option, an
amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written. When a security is purchased or sold through an
exercise of an option, the related premium paid (or received) is
added to (or deducted from) the basis of the security acquired or
deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the
premiums received or paid (or gain or loss to the extent the cost of
the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(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) Prepaid registration fees--Prepaid registration fees are charged
to expense as the related shares are issued.

(f) Dividends and distributions--Dividends from net investment

ABOUT INVERSE FLOATERS

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, interest rates on inverse floaters will decrease when short-
term interest rates increase and increase when short-term interest
rates decrease. Investments in inverse floaters may be characterized
as derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed
rate, tax-exempt securities. To the extent the Fund invests in
inverse securities, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in such securities.
