DEAR SHAREHOLDER:
What a difference one month can make. The stock and bond markets did
an about-face in October, as renewed optimism in many emerging markets
and more encouraging corporate earnings forecasts in the U.S. replaced
the concerns that had shaped the financial markets in recent months.
Equity markets worldwide bounced back strongly, while the major U.S.
bond indexes were off slightly as the flight to safety eased. 
While it's impossible to predict the future direction of the markets
with any degree of certainty, there are certain basic principles that
can help investors plan for their future needs.
First, investors are encouraged to take a long-term view of their
portfolios. If you can afford to leave your money invested through the
inevitable up and down cycles of the financial markets, you will
greatly reduce your vulnerability to any single decline. We know from
experience, for example, that stock prices have gone up over longer
periods of time, have significantly outperformed other types of
investments and have stayed ahead of inflation. 
Second, you can further manage your investing risk through
diversification. A stock mutual fund, for instance, is already
diversified, because it invests in many different companies. You can
increase your diversification further by investing in a number of
different stock funds, or in such other investment categories as
bonds. You should also keep money you'll need in the near future in a
more stable investment.
Finally, no matter what your time horizon or portfolio diversity, it
makes good sense to follow a regular investment plan, investing a
certain amount of money in a fund at the same time each month or
quarter and periodically reviewing your overall portfolio. By doing
so, you won't get caught up in the excitement of a rapidly rising
market, nor will you buy all your shares at market highs. While this
strategy - known as dollar cost averaging - won't assure a profit or
protect you from a loss in a declining market, it should help you
lower the average cost of your purchases. Of course, you should
consider your financial ability to continue your purchases through
periods of low price levels before undertaking such a strategy.
If you have questions, please call us at 1-800-544-8888. We are
available 24 hours a day, seven days a week to provide you the
information you need to make the investments that are right for you.
Best regards,
Edward C. Johnson 3d
PERFORMANCE: THE BOTTOM LINE
 
 
To evaluate a money market fund's historical performance, you can look
at either total return or yield. Total return reflects the change in
the value of an investment, assuming reinvestment of the fund's
dividend income and the effect of the fund's $5 account closeout fee
on an average-sized account. Yield measures the income paid by a fund.
Since a money market fund tries to maintain a $1 share price, yield is
an important measure of performance. If Fidelity had not reimbursed
certain fund expenses, the past five year and life of fund total
returns would have been lower.

CUMULATIVE TOTAL RETURNS show the fund's performance in percentage
terms over a set period - in this case, six months, one year, five
years or since the fund started on January 23, 1989. For example, if
you had invested $1,000 in a fund that had a 5% return over the past
year, the value of your investment would be $1,050. To measure how the
fund's performance stacked up against its peers, you can compare it to
the all-taxable money market funds average, which reflects the
performance of taxable money market funds with similar objectives
tracked by IBC Financial Data, Inc. The past six months average
represents a peer group of 889 money market funds.

YIELD refers to the income paid by the fund over a given period.
Yields for money market funds are usually for seven-day periods,
expressed as annual percentage rates. A yield that assumes income
earned is reinvested or compounded is called an effective yield. The
chart above shows the fund's current seven-day yield at quarterly
intervals over the past year. You can compare these yields to the all
taxable money market funds average and the bank money market deposit
account (MMDA) average. Figures for the all taxable money market funds
average are from IBC Financial Data, Inc. The MMDA average is supplied
by BANK RATE MONITOR(trademark).
COMPARING
PERFORMANCE
There are some important 
differences between a bank 
money market deposit account 
(MMDA) and a money market 
fund. First, the U.S. 
government neither insures nor 
guarantees a money market 
fund. In fact, there is no 
assurance that a money 
market fund will maintain a 
$1 share price. Second, a 
money market fund returns 
to its shareholders income 
earned by the fund's 
investments after expenses. 
This is in contrast to banks, 
which set their MMDA rates 
periodically based on current 
interest rates, competitors' 
rates, and internal criteria.

FUND TALK: THE MANAGER'S OVERVIEW
 
 
An interview with John Todd, Portfolio Manager of Spartan Money Market
Fund
Q. JOHN, WHAT WAS THE INVESTMENT ENVIRONMENT LIKE DURING THE SIX-MONTH
PERIOD THAT ENDED OCTOBER 31, 1998?
A. Despite continued strong domestic consumption, real GDP - gross
domestic product adjusted for inflation - slowed to a 1.8% annual rate
in the second quarter of 1998 from 5.5% in the first. This slowdown
reflected, in part, the effects of the Asian economic crisis and its
influence on trade and inventories. Expectations of a slowdown in
domestic growth resulted in a downward revision to corporate profit
projections. This factor, combined with Russia's mid-August currency
devaluations and default on its short-term debt, sparked declines in
stock market indexes that had reached record highs earlier in the
third quarter, and caused the yield differential between U.S.
Treasuries and all other debt obligations to widen considerably. In
addition, falling commodity prices hurt Canada - one of the main
trading partners of the U.S. - forcing that country's central bank to
raise interest rates to keep its currency from continuing to drop in
value. We saw similar currency drops and interest-rate hikes in Latin
America, where the U.S. also trades a great deal. Fears arose that
this "Asian contagion" would start to erode U.S. economic growth and
lead to further problems in both the economy and the capital markets,
which were rocked by the well-publicized problems encountered by
several highly leveraged hedge funds. 
Q. HOW DID THIS BACKDROP AFFECT MONETARY POLICY?
A. Up until mid-July, it was commonly believed that the Federal
Reserve Board might raise the rate banks charge each other for
overnight loans - the fed funds rate - to slow economic growth and
head off inflation. The Fed maintained a bias toward raising rates
until its September meeting, when it cut the fed funds rate by 0.25
percentage points to 5.25%. Explaining that it was trying to head off
slower growth in the future, the Fed's cut came amid further
deterioration in the financial markets generally and growing problems
with liquidity in the fixed-income markets specifically. Three weeks
later on October 15, the Fed - acting out of character by making an
announcement between meetings of its Open Market Committee - cut
short-term interest rates an additional one-quarter percentage point
to 5.00%, where the Fed funds rate stood at the end of the period.
This move came in response to a continued deterioration in the
fixed-income markets, and was an attempt on the Fed's part to try to
avoid a "credit crunch" - where lenders hold back from lending to even
the most creditworthy borrowers. 
Q. WHAT STRATEGY DID YOU PURSUE WITH THE FUND?
A. Throughout the period, I kept the fund's average maturity longer
than the average of its peers. In the beginning of the period, the
best opportunities were found on either end of the maturity spectrum,
so I pursued a barbell strategy - focusing on investments with very
short maturities on the one hand and one-year securities on the other.
When the economic outlook started to deteriorate and the outlook
called for declining interest rates, I looked for opportunities to
maintain the fund's maturity, shifting investments from the one-year
securities to those in the three- to six-month range. Those maturities
offered the most attractive rates and were also appealing from a
credit standpoint, given the growing uncertainty in the market about
different issuers' exposure to hedge fund-related problems.
Q. HOW DID THE FUND PERFORM?
A. The fund's seven-day yield on October 31, 1998, was 5.04%, compared
to 5.23% six months ago. For the six months that ended October 31,
1998, the fund had a total return of 2.65%, compared to 2.53% for the
all taxable money market funds average, according to IBC Financial
Data, Inc.
Q. WHAT'S YOUR OUTLOOK?
A. It appears that the Fed will probably lower interest rates at least
one more time before the end of the year, and then stand back to watch
what develops. While we've seen some improvements in the financial
markets since the Fed's latest rate decrease, things were not back to
normal at the end of October. While we probably will see the Fed drop
rates again, I think it is concerned about being too aggressive with
interest-rate cuts, especially when interest-rate-sensitive sectors in
the economy, such as housing and capital goods like automobiles, are
doing reasonably well. In the end, the Fed wants to make sure that it
has provided enough liquidity to the system and lowered rates enough
so that major financial dislocations are avoided - especially going
into the end of the calendar year, which tends to be a period of
volatility - without over-stimulating the economy.

NOTES TO FINANCIAL STATEMENTS
For the period ended October 31, 1998 (Unaudited)
 
 
1. SIGNIFICANT ACCOUNTING POLICIES.
Spartan Money Market Fund (the fund) is a fund of Fidelity Hereford
Street Trust (the trust) and is authorized to issue an unlimited
number of shares. The trust is registered under the Investment Company
Act of 1940, as amended (the 1940 Act), as an open-end management
investment company organized as a Delaware business trust. The
financial statements have been prepared in conformity with generally
accepted accounting principles which require management to make
certain estimates and assumptions at the date of the financial
statements. The following summarizes the significant accounting
policies of the fund:
SECURITY VALUATION. As permitted under Rule 2a-7 of the 1940 Act, and
certain conditions therein, securities are valued initially at cost
and thereafter assume a constant amortization to maturity of any
discount or premium.
INCOME TAXES. As a qualified regulated investment company under
Subchapter M of the Internal Revenue Code, the fund is not subject to
income taxes to the extent that it distributes substantially all of
its taxable income for its fiscal year. The schedule of investments
includes information regarding income taxes under the caption "Income
Tax Information."
INTEREST INCOME. Interest income, which includes amortization of
premium and accretion of discount, is accrued as earned. 
EXPENSES. Most expenses of the trust can be directly attributed to a
fund. Expenses which cannot be directly attributed are apportioned
among the funds in the trust.
DEFERRED TRUSTEE COMPENSATION. Under a Deferred Compensation Plan (the
Plan) non-interested Trustees must defer receipt of a portion of, and
may elect to defer receipt of an additional portion of, their annual
compensation. Deferred amounts are treated as though equivalent dollar
amounts had been invested in shares of the fund or are invested in a
cross-section of other Fidelity money market funds. Deferred amounts
remain in the fund until distributed in accordance with the Plan.
DISTRIBUTIONS TO SHAREHOLDERS. Dividends are declared daily and paid
monthly from net interest income.
SECURITY TRANSACTIONS. Security transactions are accounted for as of
trade date. Gains and losses on securities sold are determined on the
basis of identified cost.
2. OPERATING POLICIES.
JOINT TRADING ACCOUNT. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other
affiliated entities of Fidelity Management & Research Company (FMR),
may transfer uninvested cash balances into one or more joint trading
accounts. These balances are invested in one or more repurchase
agreements for U.S. Treasury or Federal Agency obligations.
2. OPERATING POLICIES - 
CONTINUED
REPURCHASE AGREEMENTS. The underlying U.S. Treasury or Federal Agency
Securities are transferred to an account of the fund, or to the Joint
Trading Account, at a bank custodian. The securities are
marked-to-market daily and maintained at a value at least equal to the
principal amount of the repurchase agreement (including accrued
interest). FMR, the fund's investment adviser, is responsible for
determining that the value of the underlying securities remains in
accordance with the market value requirements stated above.
RESTRICTED SECURITIES. The fund is permitted to invest in securities
that are subject to legal or contractual restrictions on resale. These
securities generally may be resold in transactions exempt from
registration or to the public if the securities are registered.
Disposal of these securities may involve time-consuming negotiations
and expense, and prompt sale at an acceptable price may be difficult.
At the end of the period, restricted securities (excluding 144A
issues) amounted to $194,000,000 or 2.0% of net assets.
3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES. 
MANAGEMENT FEE. As the fund's investment adviser, FMR pays all
expenses, except the compensation of the non-interested Trustees and
certain exceptions such as interest, taxes, brokerage commissions and
extraordinary expenses. FMR receives a fee that is computed daily at
an annual rate of .45% of the fund's average net assets.
FMR also bears the cost of providing shareholder services to the fund.
To offset the cost of providing these services, FMR or its affiliates
collect certain transaction fees from the fund's shareholders which
amounted to $79,000 for the period.
SUB-ADVISER FEE. As the fund's investment sub-adviser, Fidelity
Investments Money Management, Inc., a wholly owned subsidiary of FMR,
receives a fee from FMR of 50% of the management fee payable to FMR.
The fee is paid prior to any voluntary expense reimbursements which
may be in effect.
4. EXPENSE REDUCTIONS.
FMR has entered into an arrangement on behalf of the fund with the
fund's transfer agent whereby credits realized as a result of
uninvested cash balances were used to reduce a portion of the fund's
expenses. During the period, the fund's expenses were reduced by
$185,000 under this arrangement.

DEAR SHAREHOLDER:
What a difference one month can make. The stock and bond markets did
an about-face in October, as renewed optimism in many emerging markets
and more encouraging corporate earnings forecasts in the U.S. replaced
the concerns that had shaped the financial markets in recent months.
Equity markets worldwide bounced back strongly, while the major U.S.
bond indexes were off slightly as the flight to safety eased. 
While it's impossible to predict the future direction of the markets
with any degree of certainty, there are certain basic principles that
can help investors plan for their future needs.
First, investors are encouraged to take a long-term view of their
portfolios. If you can afford to leave your money invested through the
inevitable up and down cycles of the financial markets, you will
greatly reduce your vulnerability to any single decline. We know from
experience, for example, that stock prices have gone up over longer
periods of time, have significantly outperformed other types of
investments and have stayed ahead of inflation. 
Second, you can further manage your investing risk through
diversification. A stock mutual fund, for instance, is already
diversified, because it invests in many different companies. You can
increase your diversification further by investing in a number of
different stock funds, or in such other investment categories as
bonds. You should also keep money you'll need in the near future in a
more stable investment.
Finally, no matter what your time horizon or portfolio diversity, it
makes good sense to follow a regular investment plan, investing a
certain amount of money in a fund at the same time each month or
quarter and periodically reviewing your overall portfolio. By doing
so, you won't get caught up in the excitement of a rapidly rising
market, nor will you buy all your shares at market highs. While this
strategy - known as dollar cost averaging - won't assure a profit or
protect you from a loss in a declining market, it should help you
lower the average cost of your purchases. Of course, you should
consider your financial ability to continue your purchases through
periods of low price levels before undertaking such a strategy.
If you have questions, please call us at 1-800-544-8888. We are
available 24 hours a day, seven days a week to provide you the
information you need to make the investments that are right for you.
Best regards,
Edward C. Johnson 3d
PERFORMANCE: THE BOTTOM LINE
 
 
To evaluate a money market fund's historical performance, you can look
at either total return or yield. Total return reflects the change in
the value of an investment, assuming reinvestment of the fund's
dividend income and the effect of the fund's $5 account closeout fee
on an average-sized account. Yield measures the income paid by a fund.
Since a money market fund tries to maintain a $1 share price, yield is
an important measure of performance. If Fidelity had not reimbursed
certain fund expenses, the past five year and life of fund total
returns would have been lower.

CUMULATIVE TOTAL RETURNS show the fund's performance in percentage
terms over a set period - in this case, six months, one year, five
years or since the fund started on February 5, 1990. For example, if
you had invested $1,000 in a fund that had a 5% return over the past
year, the value of your investment would be $1,050. To measure how the
fund's performance stacked up against its peers, you can compare it to
the government money market funds average which reflects the
performance of government money market funds with similar objectives
tracked by IBC Financial Data, Inc. The past six months average
represents a peer group of 427 money market funds.

YIELD refers to the income paid by the fund over a given period.
Yields for money market funds are usually for seven-day periods,
expressed as annual percentage rates. A yield that assumes income
earned is reinvested or compounded is called an effective yield. The
chart above shows the fund's current seven-day yield at quarterly
intervals over the past year. You can compare these yields to the
government money market funds average and the bank money market
deposit account (MMDA) average. Figures for the government money
market funds average are from IBC Financial Data, Inc. The MMDA
average is supplied by BANK RATE MONITOR(trademark).
COMPARING
PERFORMANCE
There are some important 
differences between a bank 
money market deposit account 
(MMDA) and a money market 
fund. First, the U.S. 
government neither insures nor 
guarantees a money market 
fund. In fact, there is no 
assurance that a money 
market fund will maintain a 
$1 share price. Second, a 
money market fund returns 
to its shareholders income 
earned by the fund's 
investments after expenses. 
This is in contrast to banks, 
which set their MMDA rates 
periodically based on current 
interest rates, competitors' 
rates, and internal criteria.

FUND TALK: THE MANAGER'S OVERVIEW
 
 
An interview with Robert Litterst, Portfolio Manager of Spartan U.S.
Government Money Market Fund
Q. BOB, WHAT WAS THE INVESTMENT ENVIRONMENT LIKE AT THE START OF THE
SIX-MONTH PERIOD THAT ENDED OCTOBER 31, 1998?
A. At the beginning of the period, the Federal Reserve Board was
biased toward raising short-term interest rates in order to slow
economic growth and head off inflation. Real GDP - gross domestic
product adjusted for inflation - grew at an annual rate of 3.5% in the
four quarters that ended June 30, 1998, well above the
non-inflationary trend rate of 2% to 2.5% - the rate above which
inflation is expected to occur. An above-trend growth rate coupled
with a tight labor market - which usually leads to increased wage
costs that are passed on to the consumer in the form of price
increases - led the Fed to be concerned about rising inflation.
However, falling commodity prices and slowdowns in the manufacturing
and export sectors due to the economic crises in Asia helped subdue
inflation. 
Q. BUT MORE RECENTLY, THE MARKETS HAVE BEEN IN TURMOIL . . .
A. Yes, that's right. The events that triggered volatility in the
global markets over the past three months were Russia's default on
some of its debt and its concurrent devaluation of the ruble in
mid-August. Concern about economies in other emerging markets and the
worldwide banking system evolved from those events, and fears about
the impact of the collapse of a large hedge fund further rocked the
markets in late September. Investors around the world quickly reacted
by liquidating investments that seemed to carry risk, re-allocating
them to U.S. Treasury securities in a flight to quality. Yields on
Treasuries fell sharply, and yield spreads between U.S. Treasuries and
government agency securities widened because the latter didn't
participate fully in this rally. Into the fray stepped the Fed,
lowering key short-term interest rates at its September meeting, and
in a surprise move, again on October 15.
Q. WHAT WAS THE RATIONALE THAT CAUSED THE FED TO SHIFT FROM A BIAS
TOWARD RAISING RATES TO LOWERING THEM TWO TIMES?
A. At its September meeting, the Fed cited the need to cushion
domestic growth against the effects of weakness abroad, and added that
domestic financial conditions were not as accommodating for sustained
growth in the economy. The Fed's October reduction - which, for the
first time in many years, was announced between meetings of its Open
Market Committee - appeared to be in response to fears that a "credit
crunch" - where lenders hold back from both worthy and unworthy
borrowers - might develop after this string of events. Since the Fed's
second move, it seems as if stability is returning to world markets. 
Q. WHAT STRATEGY DID YOU PURSUE DURING THE PERIOD?
A. The fund's average maturity ranged from 50 to 65 days and generally
was longer than the average of its peers. A longer average maturity
generally is an indication that I expect falling interest rates. That
wasn't necessarily the case for the whole period. Earlier on, with a
neutral outlook toward the direction of interest rates, I invested
predominantly in the one- to three-month maturity range, but I
periodically extended into longer-maturity securities when they
offered the best value. Recently, I've been able to find attractively
priced agency securities in the three- to four-month sector of the
money market yield curve because their supply has increased markedly.
Of course, now that we've entered a period of interest-rate decreases,
I've looked for opportunities to extend the average maturity and lock
in attractive rates because it appeared they'd fall again.
Q. HOW DID THE FUND PERFORM?
A. The fund's seven-day yield on October 31, 1998, was 4.91%, compared
to 5.16% six months ago. For the six months that ended October 31,
1998, the fund had a total return of 2.61%, compared to 2.50% for the
U.S. Government money market funds average tracked by IBC Financial
Data, Inc.
Q. WHAT'S YOUR OUTLOOK AS 1998 WINDS DOWN AND WE HEAD INTO 1999?
A. There is a great deal of uncertainty in the financial markets. The
Fed's approach - and its effects on the markets - will depend on two
main factors: U.S. economic activity and the behavior of world
financial markets. Normally, we would only look to the former when
trying to discern Fed policy; historically, the U.S. economy has been
its primary focus. With respect to the U.S. economy, market indicators
have shown increasing signs of a slowdown, inflation has remained
benign, and unemployment has risen slightly. All of these variables
support the idea of further reduction in interest rates by the Fed.
More recently, the risk of systemic problems in worldwide financial
markets has exerted considerable influence on Fed policy. Those risks,
if anything, would be lessened by further reductions in rates. Looking
ahead, I believe the Fed is poised to respond to a faltering economy
or renewed uncertainty in the financial markets. As I said, I think
the odds are that rates could move lower over the next six months.

NOTES TO FINANCIAL STATEMENTS
For the period ended October 31, 1998 (Unaudited)
 
 
1. SIGNIFICANT ACCOUNTING POLICIES.
Spartan U.S. Government Money Market (the fund) is a fund of Fidelity
Hereford Street Trust (the trust) and is authorized to issue an
unlimited number of shares. The trust is registered under the
Investment Company Act of 1940, as amended (the 1940 Act), as an
open-end management investment company organized as a Delaware
business trust. The financial statements have been prepared in
conformity with generally accepted accounting principles which require
management to make certain estimates and assumptions at the date of
the financial statements. The following summarizes the significant
accounting policies of the fund:
SECURITY VALUATION. As permitted under Rule 2a-7 of the 1940 Act, and
certain conditions therein, securities are valued initially at cost
and thereafter assume a constant amortization to maturity of any
discount or premium.
INCOME TAXES. As a qualified regulated investment company under
Subchapter M of the Internal Revenue Code, the fund is not subject to
income taxes to the extent that it distributes substantially all of
its taxable income for its fiscal year. The schedule of investments
includes information regarding income taxes under the caption "Income
Tax Information."
INTEREST INCOME. Interest income, which includes amortization of
premium and accretion of discount, is accrued as earned. 
EXPENSES. Most expenses of the trust can be directly attributed to a
fund. Expenses which cannot be directly attributed are apportioned
among the funds in the trust.
DISTRIBUTIONS TO SHAREHOLDERS. Dividends are declared daily and paid
monthly from net interest income.
SECURITY TRANSACTIONS. Security transactions are accounted for as of
trade date. Gains and losses on securities sold are determined on the
basis of identified cost.
2. OPERATING POLICIES.
JOINT TRADING ACCOUNT. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other
affiliated entities of Fidelity Management & Research Company (FMR),
may transfer uninvested cash balances into one or more joint trading
accounts. These balances are invested in one or more repurchase
agreements for U.S. Treasury or Federal Agency obligations.
REPURCHASE AGREEMENTS. The underlying U.S. Treasury or Federal Agency
securities are transferred to an account of the fund, or to the Joint
Trading Account, at a bank custodian. The securities are
marked-to-market daily and maintained at a value at least equal to the
principal amount of the repurchase agreement (including accrued
interest). FMR, the fund's investment adviser, is responsible for
determining that the value of the underlying securities remains in
accordance with the market value requirements stated above. 
3. JOINT TRADING ACCOUNT. 
At the end of the period, the fund had 20% or more of its total
investments in repurchase agreements through a joint trading account.
These repurchase agreements were with entities whose creditworthiness
has been reviewed and found satisfactory by FMR.   The investments in
repurchase agreements through the joint trading account are summarized
as follows:

DEAR SHAREHOLDER:
What a difference one month can make. The stock and bond markets did
an about-face in October, as renewed optimism in many emerging markets
and more encouraging corporate earnings forecasts in the U.S. replaced
the concerns that had shaped the financial markets in recent months.
Equity markets worldwide bounced back strongly, while the major U.S.
bond indexes were off slightly as the flight to safety eased. 
While it's impossible to predict the future direction of the markets
with any degree of certainty, there are certain basic principles that
can help investors plan for their future needs.
First, investors are encouraged to take a long-term view of their
portfolios. If you can afford to leave your money invested through the
inevitable up and down cycles of the financial markets, you will
greatly reduce your vulnerability to any single decline. We know from
experience, for example, that stock prices have gone up over longer
periods of time, have significantly outperformed other types of
investments and have stayed ahead of inflation. 
Second, you can further manage your investing risk through
diversification. A stock mutual fund, for instance, is already
diversified, because it invests in many different companies. You can
increase your diversification further by investing in a number of
different stock funds, or in such other investment categories as
bonds. You should also keep money you'll need in the near future in a
more stable investment.
Finally, no matter what your time horizon or portfolio diversity, it
makes good sense to follow a regular investment plan, investing a
certain amount of money in a fund at the same time each month or
quarter and periodically reviewing your overall portfolio. By doing
so, you won't get caught up in the excitement of a rapidly rising
market, nor will you buy all your shares at market highs. While this
strategy - known as dollar cost averaging - won't assure a profit or
protect you from a loss in a declining market, it should help you
lower the average cost of your purchases. Of course, you should
consider your financial ability to continue your purchases through
periods of low price levels before undertaking such a strategy.
If you have questions, please call us at 1-800-544-8888. We are
available 24 hours a day, seven days a week to provide you the
information you need to make the investments that are right for you.

PERFORMANCE: THE BOTTOM LINE
 
 
To evaluate a money market fund's historical performance, you can look
at either total return or yield. Total return reflects the change in
the value of an investment, assuming reinvestment of the fund's
dividend income and the effect of the fund's $5 account closeout fee
on an average-sized account. Yield measures the income paid by a fund.
Since a money market fund tries to maintain a $1 share price, yield is
an important measure of performance. If Fidelity had not reimbursed
certain fund expenses, the past five year and past 10 year total
returns would have been lower.

CUMULATIVE TOTAL RETURNS show the fund's performance in percentage
terms over a set period - in this case, six months, one year, five
years or 10 years. For example, if you had invested $1,000 in a fund
that had a 5% return over the past year, the value of your investment
would be $1,050. To measure how the fund's performance stacked up
against its peers, you can compare it to the 100% U.S. Treasury money
market funds average which reflects the performance of 100% U.S.
Treasury money market funds with similar objectives tracked by IBC
Financial Data, Inc. The past six months average represents a peer
group of 35 money market funds.

YIELD refers to the income paid by the fund over a given period.
Yields for money market funds are usually for seven-day periods,
expressed as annual percentage rates. A yield that assumes income
earned is reinvested or compounded is called an effective yield. The
chart above shows the fund's current seven-day yield at quarterly
intervals over the past year. You can compare these yields to the 100%
U.S. Treasury money market funds average and the bank money market
deposit account (MMDA) average. Figures for the 100% U.S. Treasury
money market funds average are from IBC Financial Data, Inc. The MMDA
average is supplied by BANK RATE MONITOR(trademark).
COMPARING
PERFORMANCE
There are some important 
differences between a bank 
money market deposit account 
(MMDA) and a money market 
fund. First, the U.S. 
government neither insures nor 
guarantees a money market 
fund. In fact, there is no 
assurance that a money 
market fund will maintain a 
$1 share price. Second, a 
money market fund returns 
to its shareholders income 
earned by the fund's 
investments after expenses. 
This is in contrast to banks, 
which set their MMDA rates 
periodically based on current 
interest rates, competitors' 
rates, and internal criteria.

FUND TALK: THE MANAGER'S OVERVIEW
 
 
An interview with Robert Litterst, Portfolio Manager of Spartan U.S.
Treasury Money Market Fund
Q. BOB, WHAT WAS THE INVESTMENT ENVIRONMENT LIKE AT THE START OF THE
SIX-MONTH PERIOD THAT ENDED OCTOBER 31, 1998?
A. At the beginning of the period, the Federal Reserve Board was
biased toward raising short-term interest rates in order to slow
economic growth and head off inflation. Real GDP - gross domestic
product adjusted for inflation - grew at an annual rate of 3.5% in the
four quarters that ended June 30, 1998, well above the
non-inflationary trend rate of 2% to 2.5% - the rate above which
inflation is expected to occur. An above-trend growth rate coupled
with a tight labor market - which usually leads to increased wage
costs that are passed on to the consumer in the form of price
increases - led the Fed to be concerned about rising inflation.
However, falling commodity prices and slowdowns in the manufacturing
and export sectors due to the economic crises in Asia helped subdue
inflation. 
Q. BUT MORE RECENTLY, THE MARKETS HAVE BEEN IN TURMOIL . . .
A. That's right. The event that triggered volatility in global markets
over the past three months was Russia's default on some of its debt
and concurrent devaluation of the ruble in mid-August. Concern about
economies in other emerging markets and the worldwide banking system
evolved from those events, and fears about the impact of the collapse
of a large hedge fund further rocked the markets in late September.
Investors around the world quickly reacted by liquidating investments
that seemed to carry risk, re-allocating them to U.S. Treasury
securities in a flight to quality. Yields on Treasuries fell - and
their prices rose - extremely sharply. Into the fray stepped the Fed,
lowering key short-term interest rates at its September meeting, and
in a surprise move, again on October 15.
Q. WHAT WAS THE RATIONALE THAT CAUSED THE FED TO SHIFT FROM A BIAS
TOWARD RAISING RATES TO LOWERING THEM TWO TIMES?
A. At its September meeting, the Fed cited the need to cushion
domestic growth against the effects of weakness abroad, and added that
domestic financial conditions were not as accommodating for sustained
growth in the economy. The Fed's October reduction - which, for the
first time in many years, was announced between meetings of its Open
Market Committee - appeared to be in response to fears that a "credit
crunch" - where lenders hold back from both worthy and unworthy
borrowers - might develop after this string of events. Since the Fed's
second move, it seems as if stability is returning to world markets. 
Q. WHAT STRATEGY DID YOU PURSUE DURING THE PERIOD?
A. The fund's average maturity ranged from 60 to 85 days and generally
was longer than the average of its peers. A longer average maturity
generally is an indication that falling interest rates are expected.
That wasn't necessarily the case for the whole period. Earlier on,
with a neutral outlook toward the direction of interest rates, I
invested in longer-term money market securities because they offered
the best value. Of course, when we entered a period of interest-rate
decreases, I looked for opportunities to extend the average maturity
and lock in attractive rates because it appeared they'd fall again. 
Q. HOW DID THE FUND PERFORM?
A. The fund's seven-day yield on October 31, 1998, was 4.59%, compared
to 4.94% six months ago. For the six months that ended October 31,
1998, the fund had a total return of 2.46%, compared to 2.33% for the
U.S. Treasury money market funds average tracked by IBC Financial
Data, Inc.
Q. WHAT'S YOUR OUTLOOK AS 1998 WINDS DOWN AND WE HEAD INTO 1999?
A. There is a great deal of uncertainty in the financial markets. The
Fed's approach - and its effects on the markets - will depend on two
main factors: U.S. economic activity and the behavior of world
financial markets. Normally, we would only look to the former when
trying to discern Fed policy; historically, the U.S. economy has been
its primary focus. With respect to the U.S. economy, market indicators
are showing increasing signs of a slowdown, inflation remains benign
and unemployment has risen slightly. All of these variables support
the idea of a further reduction in interest rates by the Fed. More
recently, the risk of systemic problems in worldwide financial markets
has exerted considerable influence on Fed policy.  Those risks, if
anything, would be lessened by a further reduction in rates. Looking
ahead, I believe the Fed is poised to respond to a faltering economy
or renewed uncertainty in the financial markets. As I said, I think
the odds are that rates could move lower over the next six months.

NOTES TO FINANCIAL STATEMENTS
For the period ended October 31, 1998 (Unaudited)
 
 
1. SIGNIFICANT ACCOUNTING POLICIES.
Spartan U.S. Treasury Money Market Fund (the fund) is a fund of
Fidelity Hereford Street Trust (the trust) and is authorized to issue
an unlimited number of shares. The trust is registered under the
Investment Company Act of 1940, as amended (the 1940 Act), as an
open-end management investment company organized as a Delaware
business trust. The financial statements have been prepared in
conformity with generally accepted accounting principles which require
management to make certain estimates and assumptions at the date of
the financial statements. The following summarizes the significant
accounting policies of the fund:
SECURITY VALUATION. As permitted under Rule 2a-7 of the 1940 Act, and
certain conditions therein, securities are valued initially at cost
and thereafter assume a constant amortization to maturity of any
discount or premium.
INCOME TAXES. As a qualified regulated investment company under
Subchapter M of the Internal Revenue Code, the fund is not subject to
income taxes to the extent that it distributes substantially all of
its taxable income for its fiscal year. The schedule of investments
includes information regarding income taxes under the caption "Income
Tax Information."
INTEREST INCOME. Interest income, which includes amortization of
premium and accretion of discount, is accrued as earned. 
EXPENSES. Most expenses of the trust can be directly attributed to a
fund. Expenses which cannot be directly attributed are apportioned
among the funds in the trust.
DISTRIBUTIONS TO SHAREHOLDERS. Dividends are declared daily and paid
monthly from net interest income.
SECURITY TRANSACTIONS. Security transactions are accounted for as of
trade date. Gains and losses on securities sold are determined on the
basis of identified cost.
2. OPERATING POLICIES.
REVERSE REPURCHASE AGREEMENTS. At all times that a reverse repurchase
agreement is outstanding, the fund identifies cash and liquid
securities as segregated in its custodian records with a value at
least equal to its obligation under the agreement. On October 31,
1998, the following reverse repurchase agreements were outstanding:

</TABLE>
 
3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES. 
MANAGEMENT FEE. As the fund's investment adviser, Fidelity Management
& Research Company (FMR) pays all expenses, except the compensation of
the non-interested Trustees and certain exceptions such as interest,
taxes, brokerage commissions and extraordinary expenses. FMR receives
a fee that is computed daily at an annual rate of .45% of the fund's
average net assets. 
FMR also bears the cost of providing shareholder services to the fund.
To offset the cost of providing these services, FMR or its affiliates
collect certain transaction fees from the fund's shareholders which
amounted to $13,000 for the period. 
SUB-ADVISER FEE. As the fund's investment sub-adviser, Fidelity
Investments Money Management, Inc., a wholly owned subsidiary of FMR,
receives a fee from FMR of 50% of the management fee payable to FMR.
The fee is paid prior to any voluntary expense reimbursements which
may be in effect.
4. EXPENSE REDUCTIONS.
FMR has entered into an arrangement on behalf of the fund with the
fund's transfer agent whereby credits realized as a result of
uninvested cash balances were used to reduce a portion of the fund's
expenses. During the period, the fund's expenses were reduced by
$60,000 under this arrangement.
