DEAR SHAREHOLDER


Gross domestic product (GDP) growth rose 4.1% in the first quarter
of 1999, as robust consumer spending continued to fuel US growth and
prop up flagging economies globally. US consumer spending rose 6.8%
in the first quarter of 1999, the fastest pace in nearly 15 years.
In addition, had the US trade deficit not reached record levels in
the quarter, GDP would have been reported much higher. Consequently,
as a result of excessive growth, inflationary fears were kindled in
the financial markets and interest rates rose during the three-month
period ended May 31, 1999.

Many sectors of the US economy continued to remain vibrant. In
April, new home sales were reported at a 978,000-unit rate, the
second highest level ever recorded while vehicle sales in April rose
to a 13-year high. The manufacturing sector was strong and appeared
to be gaining momentum as the National Association of Purchasing
Managers Index (NAPM), a measure of strength within the
manufacturing sector of the US economy, rose to a 19-month high in
May. More interestingly, strength within the manufacturing sector
appeared to be broad based as every component within the NAPM index
rose in May, with the exception of inventory accumulation. US labor
market conditions remained taut. Although non-farm payrolls were
reported to have decreased by 5,000 in May, the US unemployment rate
continued to decline and is currently near a 29-year low of 4.3%.
More importantly, hourly wages rose 0.4% in June and are up 3.7%
from a year ago, compared to a 3.5% year-over-year rise the previous
two months. As a result of these series of strong economic reports,
the Federal Reserve Board adopted a tightening toward monetary
policy at its Federal Open Market Committee meeting in May. The
Federal Reserve Board ultimately raised the Federal Funds rate 0.25%
to 5.00% after the quarter's close on June 30, 1999.

Recent statements from Federal Reserve Board officials indicated
they were becoming more concerned about the US economy growing too
quickly. Although economic growth is exceptionally strong,
inflationary pressures have yet to emerge. The core consumer price
index (CPI), a broad measure of inflation excluding volatile food
and energy costs, is up just 1.8% this year through May and 2.2%
over the last 12 months. The last time the core CPI was this low
over a 12-month period was in 1966. The inflation outlook remains
positive as well. With the exception of the labor market, the US
economy did not face any binding resource constraints. Capacity
utilization rates were low and continued to create capacity
overhang. This is the primary reason US corporations lacked the
ability to raise prices.

With inflation currently at a 33-year low, we believe the likelihood
of a protracted series of interest rate hikes by the Federal Reserve
Board is minimal, for two reasons. First, with the possible
exception of wage pressures, there are no indications other sectors
of the economy are experiencing inflationary strains. Second, while
many foreign countries have rebounded nicely from last year's global
economic turmoil, there are still several countries in the midst of
the recovery process. A sharp increase in US interest rates could be
detrimental to the global economy. Key economic indicators, which
dictate Federal Reserve Board policy, are employment reports, retail
sales reports and CPI reports. On June 30, 1999, the Federal Reserve
Board did increase interest rates 0.25%.


Fiscal Year in Review
The 12-month period ended May 31, 1999 proved to be challenging for
fixed-income investors. Although intermediate-term and long-term
interest rates began and ended the fiscal year essentially
unchanged, interim volatility proved quite taxing for the adjustable
rate mortgage securities (ARMS) market. As the fiscal year unfolded,
the spread between short-term US Treasury yields and long-term US
Treasury yields narrowed. The flattening of the US Treasury yield
curve caused fixed mortgage rates to become more attractive relative
to adjustable mortgage rates, increasing the refinancing incentive
of ARMS. As a result, ARMS yield spreads widened and prices declined
to compensate for the increase in prepayments. During August and
September 1998, mounting global economic and financial concerns
prompted a massive flight to quality toward the US Treasury market,
causing US interest rates to fall dramatically. Consequently, credit
spreads in virtually all fixed-income sectors widened significantly
as a temporary credit paralysis gripped investors.

In an effort to loosen the credit strains, the Federal Reserve Board
eased monetary policy by lowering the Federal Funds rate a total of
0.75% on three separate occasions. This proved to be a boon for US
homeowners as fixed mortgage rates fell to their lowest level in
nearly 30 years. However, ARMS came under further pressure as
prepayments once again soared, causing yield spreads to increase to
their broadest levels in over eight years. As 1999 began, concerns
of widespread global economic gloom slowly subsided. However, US
interest rates began to rise on reports of stronger-than-expected
economic growth. Despite rising interest rates, the performance of
ARMS in 1999 has been stellar as yield spreads narrowed and prices
rose. In fact, the ARMS sector has been one of the few fixed-income
sectors to generate a positive total rate of return in 1999 through
May.

In light of the difficult environment during the 12 months ended May
31, 1999, we employed three key strategies that we believe helped
limit portfolio volatility and contributed to our investment
performance over the past year. First, we kept the Fund's effective
duration within a 0.50-year--0.75-year range throughout the majority
of the period. (Duration is a measure of a security's price
sensitivity to interest rate changes.) This helped to make the
Fund's net asset values less sensitive to the increased interest
rate volatility during the period. Second, we actively strove to
keep the rate-reset distribution of our ARM securities balanced. By
effectively balancing the Fund's rate resets over the entire year,
we were able to avoid wide swings in the Fund's yields as a result
of the volatile interest rate environment. Finally, as global
economic conditions began to deteriorate last fall, we reduced our
ARMS holdings to 70% of net assets (the Fund must hold a minimum of
65% of adjustable rate securities). We offset our reduced ARM
exposure with short-term agency debentures, which benefited from the
flight to quality rally in the US Treasury market. This allowed us
to avoid some of the negative impact of the yield spread widening
and resulting price declines on the Fund's net asset values.
However, in early 1999 we increased the Fund's holdings of ARMS to
87% of net assets in view of their attractive yield spreads. This
allowed the Fund to capture some of the price appreciation as a
result of the narrowing of yield spreads.


Investment Outlook
As we begin the new fiscal year, we believe the ARMS environment is
still very attractive despite the narrowing of yield spreads earlier
this year. Although yield spreads have narrowed, they still remain
wider than their pre-global crisis levels. In addition, US interest
rates have risen sharply since the beginning of the year. As of May
31, 1999, the two-year US Treasury note rose 0.87% to 5.40%, while
the ten-year US Treasury note rose 0.97% to 5.62%. More importantly,
the US Treasury yield curve has steepened. The spread between the
three-month US Treasury bill and 30-year US Treasury bond widened
from 0.64% at the start of the year to 1.20% at the close of the
period. Higher interest rates coupled with a steeper yield curve
should reduce the incentive to refinance ARMS into fixed rate
mortgages. Consequently, we believe ARMS yield spreads may narrow
further as investor prepayment assumptions are lowered. We remain
focused on our goal of balancing attractive yields and total return
potential.


In Conclusion
We thank you for your investment in Merrill Lynch Adjustable Rate
Securities Fund, Inc., and we look forward to reviewing our outlook
and strategy with you in our next report to shareholders.

PERFORMANCE DATA


About Fund
Performance

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

* 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, as
  detailed in the Fund's prospectus. If you were a Class A shareholder
  prior to October 21, 1994, your Class A Shares were redesignated to
  Class D Shares on October 21, 1994. However, in the case of certain
  eligible investors, the shares were simultaneously exchanged for
  Class A Shares.

* 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 0.50% 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.)

* Class C Shares are subject to a distribution fee of 0.55% 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.

* Class D Shares incur a maximum initial sales charge of 4% and an
  account maintenance fee of 0.25% (but no distribution fee).

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.

                 the underlying collateral and little or no principal. Interest only
                 securities have either a nominal or a notional amount of principal.

                 periodically.
               **Mortgage-Backed Obligations are subject to principal paydowns as a
                 result of prepayments or refinancings of the underlying mortgage
                 instruments. As a result, the average life may be substantially less
                 than the original maturity.
              ***Repurchase Agreements are fully collateralized by US Government &
                 Agency Obligations.

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
Merrill Lynch Adjustable Rate Securities Fund, Inc. (the "Fund") is
registered under the Investment Company Act of 1940 as a
diversified, open-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 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--Portfolio securities which are traded
in the over-the-counter market are valued at the last available bid
price or on the basis of yield equivalents as obtained from one or
more dealers that make markets in such securities. 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). Financial
futures contracts and options thereon, which are traded on
exchanges, are stated at market value. Securities 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.

(b) Repurchase agreements--The Fund invests in US Government
securities pursuant to repurchase agreements. Under such agreements,
the counterparty agrees to repurchase the security at a mutually
agreed upon time and price. The Fund takes possession of the
underlying securities, marks to market such securities and, if
necessary, receives additional securities daily to ensure that the
contract is fully collateralized.

(c) 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.

* Options--The Fund is authorized to purchase and write covered call
and put 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.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and related 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
margins 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 is was closed.

(d) 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.



Merrill Lynch Adjustable Rate Securities Fund, Inc., May 31, 1999


NOTES TO FINANCIAL STATEMENTS (continued)


(e) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income (including amortization of
discount and premiums) is recognized on the accrual basis. Realized
gains and losses on security transactions are determined on the
identified cost basis.

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

(g) Dividends and distributions--All or a portion of the Fund's net
investment income is declared daily and paid monthly. Distributions
paid by the Fund are recorded on the ex-dividend dates.

(h) Dollar rolls--The Fund sells mortgage-backed securities for
delivery in the current month and simultaneously contracts to
repurchase substantially similar (same type, coupon and maturity)
securities on a specific future date.


2. Investment Advisory Agreement and Transactions
with Affiliates:
The Fund has entered into an Investment Advisory Agreement with
Merrill Lynch Asset Management, L.P. ("MLAM"). The general partner
of MLAM is Princeton Services, Inc. ("PSI"), an indirect wholly-

the limited partner. The Fund has entered into a Distribution
Agreement and Distribution Plans with Merrill Lynch Funds
Distributor ("MLFD" or the "Distributor"), a division of Princeton
Funds Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary
of Merrill Lynch Group, Inc.

MLAM 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 of 0.50%, on an annual basis,
of the average daily value of the Fund's net assets.

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 D                        0.25%            --

Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("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.

and MLPF&S earned dealer concessions on sales of the Fund's Class A
