  Note that 75.9% of the portfolio was invested in government agency securities
and an additional 7.5% in repurchase agreements fully secured by such
securities. Although most of these government agency securities are not backed
by the full faith and credit of the U.S. government, all carry the highest
quality ratings of the Standard & Poor's and Moody's rating services.

NOTES TO FINANCIAL STATEMENTS

LEGG MASON CASH RESERVE TRUST

(Amounts in Thousands) (Unaudited)

1. Organization and Significant Accounting Policies:

  The Legg Mason Cash Reserve Trust ("Trust") is registered under the Investment
Company Act of 1940, as amended, as an open-end, diversified management
investment company.

  Preparation of the financial statements in accordance with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts
and disclosures in the financial statements. Actual results could differ from
those estimates. The following is a summary of significant accounting policies
followed by the Trust in the preparation of its financial statements:

Security Valuation

  In accordance with Rule 2a-7, portfolio securities are valued on the basis of
amortized cost, so long as the Trust's Board of Trustees determines that this
method constitutes fair value. Under this method, securities are valued at cost
when purchased and, thereafter, a constant proportionate amortization of any
discount or premium is recorded until maturity of the security.

Security Transactions

  Security transactions are recorded on the trade date. Realized gains and
losses from security transactions are reported on an identified cost basis for
both financial reporting and federal income tax purposes.

Investment Income and Dividends to Shareholders

  Dividends are declared daily and paid monthly. Dividends payable are recorded
on the dividend record date. Net investment income for dividend purposes
consists of interest accrued, plus original issue and market discount earned,
less amortization of market premium and accrued expenses. At February 29, 2004,
dividends payable of $317 were accrued.

Federal Income Taxes

  No provision for federal income or excise taxes is required since the Trust
intends to continue to qualify as a regulated investment company and distribute
substantially all of its taxable income and capital gains to its shareholders.
Because federal income tax regulations differ from accounting principles
generally accepted in the United States of America, income and capital gains
distributions determined in accordance with tax regulations may differ from net
investment income and realized gains recognized for financial reporting
purposes. Accordingly, the character of distributions and composition of net
assets for tax purposes may differ from those reflected in the accompanying
financial statements.


10 SEMI-ANNUAL REPORT TO SHAREHOLDERS

NOTES TO FINANCIAL STATEMENTS -- CONTINUED

LEGG MASON CASH RESERVE TRUST -- CONTINUED



  For the six-month period ended February 29, 2004, the Trust realized net gains
of $8, which the Trust intends to offset against available capital loss
carryforwards for federal income tax purposes as determined at the end of the
fiscal year. As of August 31, 2003, the Trust had a capital loss carryforward of
$18, which expires in 2011.

2. Repurchase Agreements:

  The Trust may engage in repurchase agreement transactions. Under the terms of
a typical repurchase agreement, a fund takes possession of an underlying debt
obligation subject to an obligation of the seller to repurchase, and a fund to
resell, the obligation at an agreed-upon price and time, thereby determining the
yield during a fund's holding period. This arrangement results in a fixed rate
of return that is not subject to market fluctuations during the fund's holding
period. The value of the collateral is at all times at least equal to the total
amount of the repurchase obligation, including interest. In the event of
counterparty default, a fund has the right to use the collateral to satisfy the
terms of the repurchase agreement. However, there could be potential loss to the
fund in the event the fund is delayed or prevented from exercising its right to
dispose of the collateral securities, including the risk of a possible decline
in the value of the collateral securities during the period in which the fund
seeks to assert its rights. The Trust's investment adviser reviews the value of
the collateral and the creditworthiness of those banks and dealers with which
the Trust enters into repurchase agreements to evaluate potential risks.

3. Transactions With Affiliates:

  The Trust has a management agreement with Legg Mason Fund Adviser, Inc.
("LMFA"). Pursuant to this agreement, LMFA provides the Trust with management
and administrative services, for which the Trust pays a fee at an annual rate
ranging from 0.50% of the first $500 million of average daily net assets to
0.40% of average daily net assets in excess of $2 billion. Management fees of
$812 were payable to LMFA at February 29, 2004.

  Western Asset Management Company ("Adviser") serves as investment adviser to
the Trust. The Adviser is responsible for the actual investment activity of the
Trust. LMFA (not the Trust) pays the Adviser a fee at an annual rate equal to
30% of the management fee received by LMFA.

  Legg Mason Wood Walker, Incorporated ("Legg Mason"), a member of the New York
Stock Exchange, serves as distributor of the Trust. Legg Mason may receive an
annual distribution fee of up to 0.15% of the Trust's average daily net assets.
However, Legg Mason has agreed to waive 0.05% of the fee indefinitely.
Distribution and service fees of $175 were payable to Legg Mason at February 29,
2004.


                                           SEMI-ANNUAL REPORT TO SHAREHOLDERS 11


  LM Fund Services, Inc. ("LMFS"), a registered transfer agent, has an agreement
with the Trust's transfer agent to assist it with some of its duties. For this
assistance, the transfer agent paid LMFS $356 for the six months ended February
29, 2004.

  The Adviser, LMFA, Legg Mason and LMFS are wholly owned subsidiaries of Legg
Mason, Inc.

4. Trust Share Transactions:

  The Trust is authorized to issue an unlimited number of full and fractional
shares of beneficial interest (without par value). At February 29, 2004, net
assets consisted of paid-in capital of $2,226,400 and accumulated net realized
gain of $8. Since the Trust has sold and redeemed shares at a constant net asset
value of $1.00 per share, the number of shares represented by such sales and
redemptions is the same as the amounts shown below for such transactions:

ABOUT THE LEGG MASON FUNDS

Legg Mason, Inc., based in Baltimore, Maryland, has built its reputation, at
least in part, on the success of the Legg Mason Funds, introduced in 1979. The
primary purpose of our funds is to enable investors to diversify their
portfolios across various asset classes and, consequently, enjoy the stability
and growth prospects generally associated with diversification.

The success of our funds is contingent on the experience, discipline, and acumen
of our fund managers. We believe the quality of our managers is crucial to
investment success. Unlike many firms, which focus on a particular asset class
or the fluctuations of the market, at Legg Mason we focus on providing a
collection of top-notch managers in all the major asset classes.
