JOINT LETTER TO SHAREHOLDERS
Dear Shareholder:
    We are pleased to provide you with the semi-annual reports for Dreyfus
Cash Management, Dreyfus Cash Management Plus, Dreyfus Government Cash
Management, Dreyfus Treasury Cash Management and Dreyfus Treasury Prime Cash
Management, each for the six-month period ended July 31, 1997. The report for
each of these Dreyfus Cash Management Funds has been consolidated into this
single document.
Economic Review
    The latest government data continued to show the U.S. economy growing at
a somewhat decelerated pace, with real Gross Domestic Product (GDP) falling
to approximately 2.2% during the April-to-June quarter. In June, stronger
chain store activity was balanced by tumbling vehicle sales, while the big
three car makers sweetened sales incentive plans, signaling a belief that
demand will remain on the soft side through the summer. In fact, consumer
spending has been weak since the spring, expanding at just 0.8% in the second
quarter. Nonetheless, many economists expect growth to pick up again,
pointing to brisk capital outlays by businesses and a combination of low
interest rates, high consumer confidence, steady job gains, huge wealth
creation, and rising disposable income that should soon jump-start consumer
spending.
    Meanwhile, the economy's strength continues to be complemented by a
virtual lack of inflation. With consumer prices rising just 1.4% during the
second quarter, inflation is running at its lowest pace in 34 years.
Moreover, U.S. producer prices fell a record seventh consecutive month in
July, and falling gold and oil prices have supported the view that inflation
is also subdued globally. As expected, the Federal Reserve Board's Open
Market Committee (FOMC) left interest rates alone at its July meeting, while
Fed Chairman Alan Greenspan all but ruled out a move to tighten monetary
policy anytime soon at his semi-annual testimony before the Senate on July
23. In the money market, short-term rates remained within a trading range as
market participants deemed a Fed move in August unlikely.
The Money Market
    Two factors dominated the money market in the past six months - the
outlook for the economy and the course of interest rates. For most of the
period, both performance of the economy and future expectations were very
positive. Solid growth continued, with little inflation evident in either
prices or wages. However, the Federal Reserve Board Open Market Committee,
which sets interest rate targets, became concerned about inflationary
pressures, particularly as reflected in the securities markets. This led the
Fed to raise interest rates modestly in March.
    Whether due to the Fed's preventive action or not, interest rates
simmered down in the ensuing four months, as the economy appeared headed for
a slowdown. Signs of potential excessive strength did not roil the market
until early August, when the money market once again began anticipating
higher interest rates.
Portfolio Strategy
    To deal with the environment that prevailed until July 31, 1997, we
stayed with our current strategy for each Fund of maintaining slightly longer
average maturities than the industry average relevant to each Fund. The
rationale for this strategy was to seek competitive yields for our investors,
and over the reporting period, this approach was successful. We remain
vigilant, however, for any signs of underlying change in the economic and
market environment. You may rest assured that, as we go forward, portfolio
strategy for each Fund will be adapted to prevailing market conditions in
working to bring you competitive yields.
    As each Fund enters the second half of its fiscal year, we would like to
take this opportunity to thank you for the confidence you have shown in the
Dreyfus organization.
                                              Sincerely,

                                      [Patricia A. Larkin signature logo]

DREYFUS CASH MANAGEMENT FUNDS
JOINT LETTER TO SHAREHOLDERS
Dear Shareholder:
    We are pleased to provide you with the semi-annual reports for Dreyfus
Municipal Cash Management Plus, Dreyfus New York Municipal Cash Management
and Dreyfus Tax Exempt Cash Management, each for the six-month period ended
July 31, 1997. The report for each of these Dreyfus Cash Management Funds has
been consolidated into this single document.
ECONOMIC REVIEW
    The latest government data continued to show the U.S. economy growing at
a somewhat decelerated pace, with real Gross Domestic Product (GDP) falling
to approximately 2.2% during the April-to-June quarter. In June, stronger
chain store activity was balanced by tumbling vehicle sales, while the big
three car makers sweetened sales incentive plans, signaling a belief that
demand will remain on the soft side through the summer. In fact, consumer
spending has been weak since the spring, expanding at just 0.8% in the second
quarter. Nonetheless, many economists expect growth to pick up again,
pointing to brisk capital outlays by businesses and a combination of low
interest rates, high consumer confidence, steady job gains, huge wealth
creation, and rising disposable income that should soon jump-start consumer
spending.
    Meanwhile, the economy's strength continues to be complemented by a
virtual lack of inflation. With consumer prices rising just 1.4% during the
second quarter, inflation is running at its lowest pace in 34 years.
Moreover, U.S. producer prices fell a record seventh consecutive month in
July, and falling gold and oil prices have supported the view that inflation
is also subdued globally. As expected, the Federal Reserve Board's Open
Market Committee (FOMC) left interest rates alone at its July meeting, while
Fed Chairman Alan Greenspan all but ruled out a move to tighten monetary
policy anytime soon at his semi-annual testimony before the Senate on July
23. In the money market, short-term rates remained within a trading range as
market participants deemed a Fed move in August unlikely.
MARKET ENVIRONMENT/PORTFOLIO ACTIVITY
    Each year, as summer approaches, the short-term municipal market
experiences volatility that is reflective of the changing patterns of supply
and demand conditions during the period. These market "technicals" require
adjustments to portfolio strategy in anticipation of conditions such as an
increase in available securities due to fund redemptions (April tax season),
a dearth of supply of high quality issues (end of June maturities), and
substantial new money market issuance (mid-July financings). Our portfolio
adjustments attempt to structure each Fund in such a way as to take advantage
of these changing conditions in an effort to enhance each Fund's return while
maintaining our commitment to high quality holdings.
    In response to the changes we anticipated in both cash flow and supply
conditions, we began preparations in early June for extending the average
maturities for each Fund. By creating a calendar of upcoming new issues (both
general market names and New York-exempt issues) and by subjecting each new
issue to rigorous in-house credit review, we were positioned to take
advantage of those notes which we believed would be attractive holdings for
each Fund. With the exception of New York Municipal Cash Management, where
the lack of supply of suitable New York paper restrained the maturity
extension to some degree, we committed to high quality issues that lengthened
the Fund's average maturity to the 60-day-plus range. We expect to continue
to purchase notes selectively in the coming months in seeking to maximize
each Fund's current yield. As we endeavor to accomplish this, we will
continue to commit to those issues which meet our high quality investment
guidelines and which provide the appropriate level of liquidity for each
Fund's needs. In Municipal Cash Management Plus, our higher commitment to
issues subject to the Alternative Minimum Tax (AMT) is designed to further
enhance the Fund's return. Additionally, in all three Funds, we will monitor
any conditions which affect our marketplace and adjust our investment policy
where necessary to pursue competitive returns.
    Included in this report is a series of detailed statements about your
Fund's holdings and its financial condition. We hope they are informative.
Please know that we appreciate greatly your continued confidence in each Fund
and in The Dreyfus Corporation.

                           Very truly yours,

                           [Richard J. Moynihan signature logo]

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
NOTE 1-SIGNIFICANT ACCOUNTING POLICIES:
    Dreyfus Cash Management, Dreyfus Cash Management Plus, Inc., Dreyfus
Government Cash Management, Dreyfus Treasury Cash Management, Dreyfus
Treasury Prime Cash Management, Dreyfus Municipal Cash Management Plus,
Dreyfus Tax Exempt Cash Management and Dreyfus New York Municipal Cash
Management (each, a "Fund" and collectively, the "Funds") are open-end
management investment companies registered under the Investment Company Act
of 1940 (the "Act"). Each Fund's investment objective is to provide investors
with as high a level of current income as is consistent with the preservation
of capital and the maintenance of liquidity and, in the case of Dreyfus
Municipal Cash Management Plus and Dreyfus Tax Exempt Cash Management only,
which is exempt from Federal income tax, and, in the case of Dreyfus New York
Municipal Cash Management only, which is exempt from Federal, New York State
and New York City income taxes. The Dreyfus Corporation (the "Manager")
serves as each Fund's investment adviser. The Manager is a direct subsidiary
of Mellon Bank, N.A.
    Premier Mutual Fund Services, Inc. (the "Distributor") is the distributor
of each Fund's shares, which are sold without a front end sales load. Each
Fund offers the following classes of shares: Institutional Shares,
Administrative Shares, Investor Shares and Participant Shares. Administrative
Shares, Investor Shares and Participant Shares are subject to a Service Plan
adopted pursuant to Rule 12b-1 under the Act. Other differences between the
classes include the services offered to and the expenses borne by each class
and certain voting rights.
    It is each Fund's policy to maintain a continuous net asset value per
share of $1.00; each Fund has adopted certain investment, portfolio valuation
and dividend and distribution policies to enable it to do so. There is no
assurance, however, that any Fund will be able to maintain a stable net asset
value per share of $1.00.
    Each Fund's financial statements are prepared in accordance with
generally accepted accounting principles which may require the use of
management estimates and assumptions. Actual results could differ from those
estimates.
    (a) Portfolio valuation: Investments are valued at amortized cost, which
has been determined by each Fund's Board Members to represent the fair value
of such Fund's investments.
    (b) Securities transactions and investment income: Securities
transactions are recorded on a trade date basis. Realized gain and loss from
securities transactions are recorded on the identified cost basis. Interest
income, adjusted for amortization of premiums and original issue discount on
investments, is earned from settlement date and recognized on the accrual
basis. Cost of investments represents amortized cost.
    Dreyfus New York Municipal Cash Management follows an investment policy
of investing primarily in municipal obligations of one state. Economic
changes affecting the state and certain of its public bodies and
municipalities may affect the ability of issuers within the state to pay
interest on, or repay principal of, municipal obligations held by the Fund.
    Dreyfus Cash Management, Dreyfus Cash Management Plus, Inc., Dreyfus
Government Cash Management and Dreyfus Treasury Cash Management may enter
into repurchase agreements with financial institutions, deemed to be
creditworthy by the Fund's Manager, subject to the seller's agreement to
repurchase and the Fund's agreement to resell such securities at a mutually
agreed upon price. Securities purchased subject to repurchase agreements are
deposited with the Fund's custodians and, pursuant to the terms of the
repurchase agreement, must have an aggregate market value greater than or
equal to the repurchase price plus accrued interest at all times. If the
value of the underlying securities falls below the value of the repurchase
price plus accrued interest, the Fund will require the seller to deposit
additional collateral by the next business day. If the request for additional
collateral is not met, or the seller defaults on its repurchase obligation,
the Fund maintains the right to sell the underlying securities at market
value and may claim any resulting loss against the seller.
    (c) Dividends to shareholders: It is the policy of each Fund to declare
dividends from investment income-net on each business day. Such dividends are
paid monthly. Dividends from net realized capital gain are normally declared
and paid annually, but the Fund may make distributions on a more frequent
basis to comply with the distribution requirements of the Internal Revenue
Code. To the extent that net realized capital gain can be offset by capital
loss carryovers, it is the policy of each Fund not to distribute such gain.
    (d) Federal income taxes: It is the policy of each Fund to continue to
qualify as a regulated investment company, if such qualification is in the
best interests of its shareholders, by complying with the applicable
provisions of the Internal Revenue Code, and to make distributions of taxable
income sufficient to relieve it from substantially all Federal income and
excise taxes.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
    The following summarizes each Fund's unused capital loss carryovers
available for Federal income tax purposes to be applied
against future net securities profits, if any, realized subsequent to January
31, 1997. The carryover does not include net realized securities losses from
November 1, 1996 through January 31, 1997 which are treated, for Federal
income tax purposes, as arising in fiscal 1998:

    At July 31, 1997, the cost of investments for Federal income tax purposes
was substantially the same as the cost for financial reporting purposes (see
the Statements of Investments).
NOTE 2-Management Fees and Other Transactions With Affiliates:
    (a) Pursuant to a separate management agreement with the Manager, the
management fee of each Fund is computed at the annual rate of .20 of 1% of
the value of such Fund's average daily net assets and is payable monthly.
    Unless the Manager gives a Fund's investors at least 90 days notice to
the contrary, the Manager, and not the Fund, will be liable for Fund expenses
(exclusive of taxes, brokerage, interest on borrowings and extraordinary
expenses) other than the following expenses, which will be borne by the Fund:
the management fee and, with respect to the Fund's Administrative Shares,
Investor Shares and Participant Shares, Rule 12b-1 Service Plan expenses.
    (b) Under each Fund's Service Plan (the "Plan") adopted pursuant to Rule
12b-1 under the Act, relating to each Fund's Administrative Shares, Investor
Shares and Participant Shares, each Fund (a) reimburses the Distributor for
distributing such classes of shares and (b) pays the Manager, Dreyfus Service
Corporation, a wholly-owned subsidiary of the Manager, and their affiliates
(collectively, "Dreyfus") for advertising and marketing relating to such
classes of shares and for providing certain services relating to shareholder
accounts in such classes of shares, such as answering shareholder inquiries
regarding the Fund and providing reports and other information, and services
related to the maintenance of shareholder accounts ("Servicing"), at an
aggregate annual rate of .10, .25 and .40 of 1% of the value of the average
daily net assets of Administrative Shares, Investor Shares and Participant
Shares, respectively. Both the Distributor and Dreyfus may pay one or more
Service Agents (a securities dealer, financial institution or other industry
professionals) a fee in respect of a Fund's Administrative Shares, Investor
Shares and Participant Shares owned by shareholders with whom the Service
Agent has a Servicing relationship or for whom the Service Agent is the
dealer or holder of record. Both the Distributor and Dreyfus determine the
amounts, if any, to be paid to Service Agents under the Plan and the basis on
which such payments are made. The fees payable under each Plan are payable
without regard to actual expenses incurred.
    (c) Each Fund (except for Dreyfus New York Municipal Cash Management)
pays its Board members an annual fee of $3,000 and an attendance fee of $500
per meeting. Dreyfus New York Municipal Cash Management pays its Board
members an annual fee of $1,000 and an attendance fee of $500 per meeting.
These amounts are borne by the Manager as to each Fund pursuant to the
undertakings in effect. See Note 2 (a).
NOTE 3-CAPITAL SHARE TRANSACTIONS:
    Each Fund (except for Dreyfus Cash Management Plus, Inc.) is authorized
to issue an unlimited number of $.001 par value shares of beneficial
interest. Dreyfus Cash Management Plus, Inc. is authorized to issue 15
billion shares of $.001 par value Common Stock.
