YEAR 2000 ISSUES (UNAUDITED)

  The  fund  could  be  adversely  affected  if the computer systems used by The
Dreyfus  Corporation  and  the  fund' s  other service providers do not properly
process  and  calculate date-related information from and after January 1, 2000.
The  Dreyfus  Corporation  is working to avoid Year 2000-related problems in its
systems  and  to  obtain  assurances  from other service providers that they are
taking  similar  steps.  In  addition,  issuers  of securities in which the fund
invests may be adversely affected by Year 2000-related problems. This could have
an impact on the value of the fund's investments and its share price.

LETTER TO SHAREHOLDERS

Dear Shareholders:

  We  are  pleased to report the performance for the Dreyfus U.S. Treasury Short
Term Fund. For the 12-month period ended December 31, 1998, your Fund produced a
total  return,  including  share price changes and dividend income generated, of
6.14% .*  Income  dividends  paid  from  net investment income during the period
amounted to approximately $0.874 per share, representing a distribution rate per
share of 5.91%.**

ECONOMIC REVIEW

  During  1998,  the  main  regions  of  the  world  had very different economic
fundamentals.  The  U.S.  entered  the  year  with  a  strong  economy near full
employment, with unemployment only slightly above 4%. The tight labor market led
the  Federal  Reserve Board to contemplate a rise in interest rates early in the
year,  but  world  economic  weakness  generated powerful enough disinflationary
forces  that  the Fed acted instead to ease credit beginning in September. After
many  years of subpar economic growth, continental Europe moved into a sustained
economic  expansion. The overall European economy benefited as interest rates in
peripheral  countries such as Spain and Italy fell, approaching the lower levels
established  by  Germany,  on  the eve of currency unification. Unlike the U.S.,
Europe  has  substantial excess capacity of productive plant and labor. In Asia,
weak  economies  were  pervasive  as  a  result of a financial crisis. The Latin
American  economies weakened in turn as the financial stresses spread throughout
that  region. On balance, there was a substantial weakening of the world economy
over  the  course  of  1998  moderated mainly by the American consumer's role as
"spender of last resort."

A main influence on the U.S. economy during the year was the foreign financial
crisis  and  consequent  cooling  of the world economy. The positive effects hit
first.  Actual  inflation  and  expected inflation dropped, causing a decline in
long-term  Treasury  bond  yields  and  mortgage  rates.  This  caused a boom in
housing.  The  fall in inflation left more of the growth in consumer income with
which to buy goods and services. Thus, consumers benefited from a combination of
good  growth  in  income after inflation, a strong labor market and increases in
the  prices  of assets they owned, including bonds, stocks and real estate. In a
sense,  1998  was  a  year  of  disinflationary boom in the U.S., as above-trend
economic growth coincided with negligible inflation.

  The  negative  effect of Asian weakness was felt in the industrial sector more
than  in  the consumer sector. Corporate profits weakened, especially in sectors
affected  by  the Asian crisis such as world-traded commodities (oil, metals and
paper)    and    exports.

  Evidence  of  a  weaker world economy accumulated during 1998 as the financial
stresses  continued.  A  worsened  financial crisis occurred between the Russian
default  in  mid-August  and  the  fallout from the Long Term Capital Management
hedge  fund crisis through early October. However, energetic steps were taken to
stabilize the Japanese banks, design a support package for Brazil, ease monetary
policy,   and  help  overinvested  financial  institutions  rebuild  their  cash
reserves.  Indications of a calming of financial fears were evident in the final
months  of  the  year.  In  any  case, there appears to have been a shift in the
priorities   of   key   policymakers   from   fighting  potential  inflation  to
restimulating future world economic growth.

  The  global  economy  survived  a  triple financial crisis in 1998 from Japan,
emerging  market  countries  and  overextended  financial  institutions.  Excess
capacity  persists  in  many  worldwide  industries  after years of high capital
spending  followed by the onset of a worldwide weakening in demand. Fortunately,
the  U.S.  has  led  the  world  in  making  the  transition  away  from the old
manufacturing  industries  to  the new growth industries, such as biotechnology,
software,  computer hardware and the Internet. This contributed to the favorable
combination  of low unemployment and low inflation in the U.S., and may yet lead
toward more efficient allocation of capital elsewhere in the world.

  As  1998 ended, interest rates set by central banks remained in a downtrend in
most  parts  of the world including Europe and the U.S. A similar trend had even
begun in many emerging countries, as the stresses of financial crisis relax.

MARKET ENVIRONMENT

  The  flight  to  quality as investors scrambled for a safe haven in 1998 meant
that  yields were propelled significantly lower. The 30-year Treasury bond began
the  year  yielding  5.925%  and  ended  the year yielding 5.096%. At one point,
yields on the same issue reached 4.72%, which was at the peak of fear. Investors
apparently  were  inclined  to  accept  these  significantly  lower  yields  for
Treasuries    in    order    to    lessen    quality    risk.

  To  put the level of fear at that time in perspective, one can look at quality
spreads. Quality spreads are the difference in yield between Treasury yields and
other  investment-  grade  securities  like corporate bonds, mortgage-backed and
government  agency  securities. In October, these quality spreads became as wide
as  those  last  seen  in  the  early  1990s during a recession. They have since
recovered somewhat.

PORTFOLIO OVERVIEW

  Given  the  market  environment,  we  kept the Fund with a longer than neutral
average  maturity.  While  we normally maintain an approximate average portfolio
maturity  of  2.5  years,  at various times during the reporting period the Fund
maintained  an  average  portfolio  maturity of its maximum of three years. This
worked out well for the Fund, as rates did decline, which increased the value of
our portfolio.

  Our  allocation  to government agencies at the end of the reporting period was
approximately  15% . Agencies were also hurt when the spreads were widening last
October.  At  the  end of the Fund's fiscal year, we believed agency yields were
attractive compared to Treasuries.

 During  the  year,  our  biggest  miss  was  the  Treasury Inflation Protected
Securities (TIPS) market. While TIPS are theoretically cheap, as we had written,
the  marketplace  could  not focus on inflation protection during a time when it
seemed    that    a    deflationary    crisis    was    looming    everywhere.

  Included  in  this report is a series of detailed statements about your Fund's
holdings  and  its  financial condition. We hope that you find them informative.
Please know that we greatly appreciate your continued confidence in the Fund and
in The Dreyfus Corporation.

                Very truly yours,


                [Gerald E. Thunelius signature]

The  above  graph  compares  a  $10,000 investment made in Dreyfus U.S. Treasury
Short  Term  Fund  on 12/31/88 to a $10,000 investment made in the Merrill Lynch
Governments,  U.S.  Treasury,  Short-Term (1-2.99 Years) Index on that date. All
dividends and capital gain distributions are reinvested.

The Fund invests at least 65% of its net assets in U.S. Treasury securities. The
Fund' s  portfolio  will, under normal market conditions, have a dollar-weighted
average  maturity  ranging  between  two and three years. The Fund's performance
shown  in  the line graph takes into account fees and expenses. Unlike the Fund,
the Merrill Lynch Governments, U.S. Treasury, Short-Term (1-2.99 Years) Index is
an  unmanaged  performance  benchmark for Treasury securities with maturities of
1-2.99 years; issues in the Index must have par amounts outstanding greater than
or  equal  to $1 billion. The Index does not take into account charges, fees and
other  expenses.  Further  information  relating  to Fund performance, including
expense  reimbursements, if applicable, is contained in the Financial Highlights
section of the Prospectus and elsewhere in this report.

DREYFUS U.S. TREASURY SHORT TERM FUND
- -----------------------------------------------------------------------------

NOTES TO FINANCIAL STATEMENTS

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

   Dreyfus  U.S.  Treasury  Short Term Fund (the "Fund") is registered under the
Investment  Company  Act  of  1940,  as  amended  (the  "Act"), as a diversified
open-end  management  investment  company. The Fund's investment objective is to
provide  investors  with as high a level of current income as is consistent with
the  preservation  of capital. The Dreyfus Corporation (the "Manager") serves as
the  Fund' s  investment  adviser.  The Manager is a direct subsidiary of Mellon
Bank,  N.A. ("Mellon"). Premier Mutual Fund Services, Inc. is the distributor of
the Fund's shares, which are sold to the public without a sales charge.

   Effective  May  15,  1998,  the Fund changed its name from "Dreyfus 100% U.S.
Treasury Short Term Fund" to "Dreyfus U.S. Treasury Short Term Fund".

   The  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  in  securities (excluding short-term
investments  other  than U.S. Treasury Bills) are valued each business day by an
independent  pricing  service  (" Service" ) approved  by the Board of Trustees.
Investments   for  which  quoted  bid  prices  are  readily  available  and  are
representative  of the bid side of the market in the judgment of the Service are
valued  at  the  mean  between the quoted bid prices (as obtained by the Service
from  dealers in such securities) and asked prices (as calculated by the Service
based  upon its evaluation of the market for such securities). Other investments
(which  constitute  a  majority of the portfolio securities) are carried at fair
value as determined by the Service, based on methods which include consideration
of:  yields  or prices of securities of comparable quality, coupon, maturity and
type;  indications  as  to  values  from  dealers; and general market condition.
Short-term  investments, excluding U.S. Treasury Bills, are carried at amortized
cost, which approximates value.

   (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,
including,  where  applicable,  amortization  of  discount  on  investments,  is
recognized  on  the accrual basis. Under the terms of the custody agreement, the
Fund  receives  net  earnings  credits  based on available cash balances left on
deposit.

   (C)  DIVIDENDS  TO  SHAREHOLDERS:  It  is  the  policy of the Fund to declare
dividends  daily  from  investment  income-net. 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 of 1986, (the
" Code" ). To the extent that net realized capital gain can be offset by capital
loss carryovers, it is the policy of the Fund not to distribute such gain.

(D) FEDERAL INCOME TAXES: It is the policy of the 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  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

   The  Fund  has  an unused capital loss carryover of approximately $14,987,000
available  for  Federal  income  tax  purposes  to be applied against future net
securities  profits,  if  any,  realized  subsequent  to  December 31, 1998. The
carryover does not include net realized securities losses from November 01, 1998
through December 31, 1998 which are treated, for Federal income tax purposes, as
arising  in  fiscal 1999. If not applied, $9,564,000 of the carryover expires in
fiscal  2002,  $2,004,000  expires  in fiscal 2003, $2,702,000 expires in fiscal
2004 and $717,000 expires in fiscal 2005.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 2--BANK LINE OF CREDIT:

   The  Fund  participates  with  other  Dreyfus-managed funds in a $100 million
unsecured  line  of  credit  primarily to be utilized for temporary or emergency
purposes,  including  the  financing  of redemptions. Interest is charged to the
Fund  at rates which are related to the Federal Funds rate in effect at the time
of borrowing. During the period ended December 31, 1998, the Fund did not borrow
under the line of credit.

NOTE 3--MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

   (A)  Pursuant  to a management agreement with the Manager, the management fee
is computed at the annual rate of
 . 60  of  1%  of the value of the Fund's average daily net assets and is payable
monthly.  The  Manager  had  undertaken from January 1, 1998 through January 28,
1998  to  reduce  the  management  fee  paid by the Fund, to the extent that the
Fund's aggregate expenses (exclusive of taxes, brokerage, interest on borrowings
and  extraordinary  expenses) exceeded specified annual percentages of the value
of  the  Fund' s  average daily net assets, and thereafter, through December 31,
1998  to  reduce  the  management  fee  paid by the Fund, to the extent that the
Fund' s  aggregate  annual  expenses (exclusive of certain expenses as described
above)  exceeded  an annual rate of .80 of 1% of the value of the Fund's average
daily  net assets. The reduction in management fee, pursuant to the undertaking,
amounted to $258,820 during the period ended December 31, 1998.

   (B)  Under the Shareholder Services Plan, the Fund reimburses Dreyfus Service
Corporation,  a  wholly-owned subsidiary of the Manager, an amount not to exceed
an  annual rate of .25 of 1% of the value of the Fund's average daily net assets
for certain allocated expenses of providing personal services and/or maintaining
shareholder  accounts.  The  services  provided  may  include  personal services
relating  to  shareholder  accounts,  such  as  answering  shareholder inquiries
regarding  the  Fund  and  providing reports and other information, and services
related  to  the  maintenance  of  shareholder accounts. During the period ended
December  31,  1998,  the  Fund was charged $285,697 pursuant to the Shareholder
Services Plan.

The Fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the
Manager,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform transfer agency services for the Fund. During the period
ended  December  31, 1998, the Fund was charged $93,069 pursuant to the transfer
agency agreement.

The Fund compensates Mellon under a custody agreement for providing custodial
services  for  the Fund. During the period ended December 31, 1998, the Fund was
charged $18,309 pursuant to the custody agreement.

   (C)  Each  trustee  who  is  not an "affiliated person" as defined in the Act
receives from the Fund an annual fee of $2,500 and an attendance fee of $250 per
meeting.  The  Chairman  of  the  Board  receives  an  additional  25%  of  such
compensation and the trustee Emeritus receives 50% of such compensation.

NOTE 4--SECURITIES TRANSACTIONS:

   The  aggregate  amount  of  purchases  and  sales  of  investment securities,
excluding  short-term  securities,  during  the  period ended December 31, 1998,
amounted to $1,370,396,212 and $1,405,169,498, respectively.

   At  December 31, 1998, accumulated net unrealized depreciation on investments
was  $1,184,329,  consisting  of  $506,146  gross  unrealized  appreciation  and
$1,690,475 gross unrealized depreciation.

At December 31, 1998, the cost of investments for Federal income tax purposes
was substantially the same as the cost for financial reporting purposes (see the
Statement of Investments).

DREYFUS U.S. TREASURY SHORT TERM FUND

   We  have  audited  the  accompanying  statement  of assets and liabilities of
Dreyfus  U.S.  Treasury  Short  Term  Fund  (formerly known as Dreyfus 100% U.S.
Treasury  Short  Term  Fund) , including  the  statement  of  investments, as of

therein.   These   financial   statements   and  financial  highlights  are  the
responsibility  of  the  Fund' s management. Our responsibility is to express an
opinion  on  these  financial  statements  and financial highlights based on our
audits.

   We  conducted  our  audits  in  accordance  with  generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether  the  financial  statements  and financial
highlights  are free of material misstatement. An audit includes examining, on a
test  basis,  evidence  supporting  the amounts and disclosures in the financial
statements  and  financial  highlights.  Our procedures included verification by
examination  of  securities  held  by  the custodian as of December 31, 1998 and
confirmation  of  securities  not  held  by the custodian by correspondence with
others.  An  audit  also  includes  assessing the accounting principles used and
significant  estimates  made  by  management,  as well as evaluating the overall
financial   statement  presentation.  We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above  present  fairly,  in  all  material  respects,  the financial position of
Dreyfus  U.S.  Treasury Short Term Fund at December 31, 1998, the results of its
operations  for  the  year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the   indicated   years,   in  conformity  with  generally  accepted  accounting
principles.
