AT VANGUARD, WE BELIEVE THAT TRADITION MATTERS

Our 8,000 crew members embrace the traditional values on which our success is
built, including integrity, hard work, thrift, teamwork, and fair dealing on
behalf of our clients. 

This year, our report cover pays homage to three anniversaries, each of great
significance to The Vanguard Group:


- - The 200th anniversary of the Battle of the Nile, which commenced on August 1,
  1798. HMS Vanguard, the victorious British flagship at the Nile, is our
  namesake. And its motto-- "Leading the way"--serves as a guiding principle for
  our company.

- - The 100th birthday, on July 23, of Walter L. Morgan, founder of Wellington
  Fund, the oldest member of what became The Vanguard Group. Mr. Morgan was
  friend and mentor to Vanguard founder John C. Bogle, and helped to shape the
  standards and business principles that Mr. Bogle laid down for Vanguard at its
  beginning nearly 25 years ago: a stress on balanced, diversified investments;
  insistence on fair dealing and candor with clients; and a focus on long-term
  investing. To our great regret, Mr. Morgan died on September 2.

- - The 70th anniversary, on December 28, of the incorporation of Vanguard
  Wellington Fund. It was the nation's first balanced mutual fund, and is one of
  only a handful of funds created in the 1920s that are still in operation.

Although Vanguard constantly tackles new challenges, adopts new technology, and
develops new services, we treasure the traditions and values that set us apart
in a crowded, competitive industry. And we salute our shareholders, whose
support and trust we strive to earn each and every day.

The Vanguard Money Market Funds achieved stalwart yields for the fiscal year
ended November 30, 1998. The total return of our Prime Money Market Fund was
+5.4%, unchanged from a year ago. Taking into account the modest 1.5% rise in
the Consumer Price Index, the fund's real, or inflation-adjusted, yield was a
healthy +3.9%, the highest it has been since our fiscal year 1989.

    The adjacent table presents the total returns for each of our money market
funds, as well as for their peers. It also shows what we call the "Vanguard
advantage," the extra income our funds provided over their competitors, the
result largely of our exceptionally low operating costs. This yield advantage
was 0.5 percentage point for shareholders in the Prime and Federal Funds and 0.3
percentage point for those in our Treasury Fund and Prime Institutional Shares.
Each fund's share price remained at $1 throughout the period, as is expected but
not guaranteed.

FINANCIAL MARKETS IN REVIEW

The U.S. economy expanded at a robust pace during the fiscal year despite
serious financial troubles that beset Asia, Russia, and Latin America. The
domestic economy's growth was fueled primarily by big increases in consumer
spending encouraged by low unemployment (4.4% as the fiscal year ended) and
strong wage growth (about 4%, well in excess of the 1.5% inflation rate).

    Interest rates fell, with the yield of the 30-year U.S. Treasury bond
declining on balance by about 1 percentage point to end the year at 5.06%. Bond
prices benefited from buying by investors seeking a haven from volatility in the
U.S. stock market and in overseas securities and currency markets. Concerns
about the impact of the international economic situation on world markets and
the U.S. economy were cited by the Federal Reserve Board as a factor in its
decision to cut short-term interest rates. The Fed shaved rates by one-quarter
of a percentage point on three occasions: September 29, October 15, and November
17. The Lehman Brothers Aggregate Bond Index, a benchmark for the overall bond
market, achieved a +9.5% return during the fiscal year, with approximately 6.8%
coming from interest income and 2.7% from price appreciation.

    Stocks seesawed dramatically during the period. The Standard & Poor's 500
Composite Stock Price Index rose strongly (+25%) through July 17, only to have
earnings 

                                       1

<PAGE>   4
decimated by a six-week slump that culminated in a -6.8% single-day decline on
August 31. Stocks then rebounded in September, and by fiscal year-end the S&P
500 Index was up +23.7%.

FISCAL 1998 PERFORMANCE OVERVIEW

The Fed's autumnal easing of monetary policy contributed to the decline in money
market interest rates during our fiscal year. At 4.48%, the yield of the 3-month
U.S. Treasury bill finished the period 72 basis points below its yield of 5.20%
on November 30, 1997. Yields on 3-month Treasuries fluctuated within a range of
185 basis points (1.85 percentage points) during fiscal 1998.

</TABLE>

    As the accompanying table shows, the annualized 7-day yields of our money
market funds on November 30, 1998, were slightly lower than they were a year
ago. In this environment of low inflation and falling interest rates, our funds'
yields were excellent. In what we daresay has become the norm, they handily
outperformed their competitors, a triumph we attribute mostly--and proudly--to
our lower operating expenses. The Prime, Federal, and Treasury Money Market
Funds each operated at an expense ratio (expenses as a percentage of average net
assets) of 0.33%, or $3.30 per $1,000 of assets, during our fiscal year. The
expense ratio of the average money market fund was 0.83%, giving us an edge of
half a percentage point. The average institutional money market fund charged a
0.44% expense ratio, nearly three times the 0.15% expense ratio of our Prime
Fund's Institutional Shares. While such differences may appear modest, they give
us a significant head start in delivering to you the higher yields you've come
to expect from our money market funds.

LONG-TERM PERFORMANCE OVERVIEW

We're happy to report that the combination of our low operating costs and the
experienced, skilled leadership of our Fixed Income Group helped make fiscal
1998 the latest in an ongoing series of banner years for the Vanguard Money
Market Funds. The adjacent table shows the average annual return for each
Vanguard fund and its average competitor over the past ten years. It also shows
the value, as of November 30, of hypothetical $10,000 investments made in each
fund a decade ago.

$10,000 initially invested. Because money market funds largely invest in the
same types of securities and vary only modestly in average maturity, the level
of operating costs makes or breaks a fund. Generally, the lower a fund's
expenses, the higher its return. Given our goal of maintaining the lowest
reasonable costs for all of our funds, we are confident that the Vanguard Money
Market Funds will continue to provide strong relative returns. Of course, all
mutual funds are subject to the vagaries of the markets and to unpredictable
changes in interest rates, and there is no way to predict absolute returns over
the next ten years. Yields could be either higher or lower than those during the
past decade.

IN SUMMARY

Money market funds do not occupy a glamorous niche within the financial world.
Their role in a balanced investment program is to be the strong, silent type--to
provide current income, liquidity, and stability of principal. These are
important attributes in helping investors to pursue short-term investment goals
and to add diversity to portfolios that also include stock funds and bond funds.
As always, we recommend that investors thoughtfully construct such a balanced
investment plan--consistent with their personal goals, time horizon, and
tolerance for risk--and then stick with it. We assure you that we, likewise,
will "stay the course" by continuing to focus on providing high-quality,
low-cost money market funds.

THE MARKETS IN PERSPECTIVE                                    
YEAR ENDED NOVEMBER 30, 1998

[PHOTO]

U.S. financial markets produced solid overall gains during the fiscal year ended
November 30. The S&P 500 Index gained 23.7% for the 12-month period, overcoming
a sharp summer setback. Bond prices rose as interest rates declined. Returns
from overseas stock markets varied widely, with big gains in Europe and losses
in most other markets.

U.S. STOCK MARKETS

The stock market's gains during the fiscal year were concentrated in
large-capitalization growth stocks. Within the S&P 500 Index, the growth stocks
rose 33.7%, while the value stocks were up 13.2%. The market's overall bias
toward large-caps showed starkly in the contrast between the S&P 500 and other
indexes. While the S&P 500 was rising 23.7%, the rest of the market returned a
paltry 2.6%, as measured by the Wilshire 4500 Equity Index. Small-cap stocks, as
represented by the Russell 2000 Index, did even worse--a negative return of
6.6%.

    The market's ascent was not without incident, even for large-cap stocks.
After rising strongly to a record high on July 17, the S&P 500 fell by 19.2%
during the following six weeks, just shy of the 20% mark generally considered
the boundary distinguishing a bear market from a mere "correction." Declines
were certifiably bearish for smaller stocks, however.

</TABLE>

    The July-August tumble in stock prices reflected a number of factors that
collectively raised the anxiety level for many investors. Among these were
deteriorating corporate earnings reports and forecasts, Russia's default on its
debts, and a continuance of economic weakness in Asia. The persistence of Asia's
economic troubles--which first surfaced in mid-1997--began to slow the economic
expansions in the United States and Europe.

    The rebound in stocks late in the fiscal year occurred even though several
sources of uncertainty remained, including doubts about global economic growth
and reductions in securities analysts' forecasts of future corporate earnings.
Stock prices got considerable help from the decline in interest rates. (Low
inflation and low interest rates help stock prices by raising the estimated
value of future dividends and earnings.)

    Three forces clearly shaped the performance of industry sectors. They could
be summarized as faith (the buoyant confidence of consumers), fear (related to
the effects of economic troubles abroad), and fortresses (companies somewhat
protected from competition).

                                       4
<PAGE>   7
    In contrast to the cautious stance of investors during fiscal 1998, U.S.
consumers threw caution to the wind. Feeling flush because of plentiful jobs
(the nation's unemployment rate was 4.4% at fiscal year-end) and rising wages,
consumers spent a record proportion of their income. Not surprisingly, then, two
big gainers among sectors of the S&P 500 Index were consumer discretionary
firms, such as retailers (+26%) and consumer staples (+22%).

    Fear was a factor in the lagging returns in industry groups considered to be
vulnerable to slowing global growth, falling commodity prices, and tougher price
competition from foreign suppliers. Among these--all traditional value
sectors--were firms in the "other energy" category (-37%); chemical and other
materials & processing firms (essentially a zero return); and makers of producer
durables such as airplanes and machinery (+2%). Conversely, utilities did well
(+35%) in part because they are seen as relatively insulated from foreign
competition or economic woes. Fortresses are companies perceived as relatively
safe from competitors because of patented products or brands. Such companies led
the year's best-performing sectors: technology (+49%) and health care (+43%).

U.S. BOND MARKETS

Interest rates declined during the fiscal year, especially for U.S. Treasury
securities, which benefited from heightened aversion to risk among investors and
from a slight decrease in supply, thanks to a $70 billion federal budget
surplus. The Federal Reserve Board had the flexibility to cut short-term rates
in three quarter-point steps in the autumn because inflation was remarkably
tame--consumer prices rose just 1.5% for our fiscal year.

    In this bond-friendly environment, yields on long-term Treasury issues fell
by roughly 100 basis points (1 percentage point), with the 30-year Treasury bond
ending the fiscal year at 5.06%. Lower rates mean higher prices for bonds, and
the Lehman Brothers Long U.S. Treasury Bond Index earned a total return of
15.7%, an astounding margin of some 14 percentage points over the inflation
rate.

    Reflecting investors' flight to quality and worries about slowing economic
growth, prices fell for high-yield "junk" bonds. Even high-quality corporate
bonds and mortgage-backed securities did not rise in price as far as Treasury
securities. Mortgage bonds tend to lag Treasuries during periods when falling
rates lead to greater refinancing activity by homeowners, resulting in unwanted
prepayments of principal. The Lehman Aggregate Bond Index, which comprises
high-quality corporate and mortgage-backed bonds as well as Treasuries, and has
an intermediate-term average maturity, earned 9.5%.

    Yields on long-term municipal bonds declined only modestly during the fiscal
year, and by November 30 were only slightly lower than yields on comparable
Treasury securities. This was striking because the interest on municipals is
exempt from federal income tax.

INTERNATIONAL STOCK MARKETS

Europe's stock markets outdistanced even the S&P 500 Index, but Asian and Latin
American markets were generally down during the fiscal year. As a group,
European stocks earned 27.8% in U.S.-dollar terms. Europe's bull market was
fueled by continuing economic growth, lower interest rates, increased corporate
merger activity, and optimism about the effects of the euro, a common currency
due to be adopted in 1999 by 11 nations.

    Japan's stock market continued to suffer from the effects of a severe
recession and a shaky banking system. Stocks in Tokyo fell 4.5% in U.S.-dollar
terms. Elsewhere in Asia, returns were mixed, ranging from a rebound of 21% in
South Korea, through Australia's 11% gain, to big losses in Indonesia (-52%),
Malaysia (-42%), New Zealand (-25%), and Singapore (-18%). Losses were steep
throughout Latin America, including Mexico (-32%), Venezuela (-59%), Brazil
(-20%), and Chile (-22%).

REPORT FROM THE ADVISER

Interest rates declined during the fiscal year ended November 30 amid waves of
global financial turmoil that have ebbed and flowed for many months and are
probably not yet over. U.S. stock and bond markets rode a rollercoaster to very
strong returns. The returns of Vanguard's Prime, Federal, and Treasury Money
Market Funds were clustered slightly above 5%, adding to a string of more than
four years of relative stability in money market yields. In light of the low
level of inflation--the Consumer Price Index was up 1.5% during our fiscal
year--the funds' annual real, or inflation-adjusted, returns were about 3.5%,
which is quite generous by historic standards. Recent developments, however,
have put downward pressure on interest rates that will most likely lead to
somewhat lower returns in the near future.

    What began in the summer of 1997 as a regional financial crisis affecting
Asia spread to emerging markets in Eastern Europe and Latin America. Years of
increasing confidence in the growth prospects and financial strength of emerging
economies had attracted massive investment flows and resulted in narrower risk
premiums--the extra returns investors expect for taking greater risk. All that
was rapidly undone in a frenzied flight to investments of the highest quality
and liquidity. The Russian government's default on its obligations in late
August was a catalyst for the most extreme market dislocations of the fiscal
year. The stock markets of developed nations plunged as investors contemplated
the impact of a global slowdown on the profits and growth of well-established
companies. Headlines about the troubles of highly leveraged "hedge funds" raised
the specter of forced liquidations. Many bond investors responded by disengaging
from credit, liquidity, and prepayment risk in favor of U.S. Treasury
securities. The perception of an imminent credit crunch--in which otherwise
healthy companies would be cut off from funding for expansion--reinforced the
downward spiral of investor confidence.

    Throughout the year, the performance of the U.S. economy stood in striking
contrast to the disruption in the global financial markets. Month after month,
economic statistics showed that job and wage growth were healthy and that key
sectors such as housing were booming, despite expectations that the problems
overseas would eventually restrain the U.S. economic juggernaut. It wouldn't be
the first time that trouble in the financial industry had caused economists to
lose sight of the fundamental strength in the heartland. However, as the
intensifying financial storm began to threaten the efficient functioning of
markets and thereby the funding of the U.S. economic machine, officials of the
Federal Reserve Board began to think more globally. Federal Reserve Chairman
Alan Greenspan remarked that it was not reasonable to expect the United States
to remain an "oasis of prosperity" in the face of so much trouble overseas. The
Fed embarked on a series of monetary-policy easings that resulted in a drop of
0.75% in the benchmark federal funds rate (the rate at which banks borrow and
lend reserves among themselves). The markets have welcomed this additional
liquidity and pledge of support from the central bank.

    In the bond markets, there has been a partial retracing of risk premiums
from their extremes, and recently the equity markets have staged a furious (some
would argue unwarranted) rally. With the federal funds rate as the cornerstone
of the money market yield curve, rates on the Treasury bills, certificates of
deposit, and commercial paper in which Vanguard's money market funds invest have
also come down. Market expectations are for the Fed to pause and evaluate the
effectiveness of its rate-cutting actions in calming the markets and sustaining
economic expansion. Given the tepid pace of inflation and lingering problems
around the globe, we think the balance of probability tips in favor of further
rate cuts.

    During the year, we have extended the average maturities of the money market
funds in anticipation of lower interest rates. We did so last spring in the
Treasury Money Market Fund as it became clear that the historic transition from
federal budget deficit to surplus would lead to a shortage of short-term
Treasury securities. In September, we extended the maturities of the Prime and
Federal Money Market Funds because we judged that the Fed was likely to swing
into action against the market crisis and cut rates.

    With regard to credit quality, we remain at the conservative end of the
money market world, as always. World events have made this a busy year for
Vanguard's skilled and experienced credit analysts, upon whom we rely to
maintain rigorous surveillance over the issuers in which we invest. They have
been more than equal to the task. As market rates head lower and fund operating
expenses consume a larger portion of returns, some fund managers may be tempted
to reach for yield by taking on riskier investments. Rest assured that this is
not our mandate. Our cost advantage over the average competing fund is lasting.
We believe that it provides shareholders with an unbeatable combination of high
quality and competitive returns.

INVESTMENT PHILOSOPHY

The funds reflect a belief that the highest level of current income consistent
with capital preservation and liquidity can be provided by holding high-quality
money market instruments issued by financial institutions, nonfinancial
corporations, the U.S. government, and federal agencies.

PERFORMANCE SUMMARY
TREASURY MONEY MARKET FUND

All of the data on this page represent past performance, which cannot be used to
predict future returns that may be achieved by the fund. Note that annual
returns can fluctuate widely. An investment in a money market fund is neither
insured nor guaranteed by the U.S. government, and there is no assurance that
the fund will be able to maintain a stable net asset value of $1 per share.

AVERAGE MATURITY. The average length of time until bonds held by
a fund reach maturity (or are called) and are repaid. In general, the longer the
average maturity, the more a fund's share price will fluctuate in response to
changes in market interest rates. 

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
ratings assigned to a fund's securities holdings by credit-rating agencies. The
agencies make their judgment after appraising an issuer's ability to meet its
obligations. Quality is graded on a scale, with Aaa or AAA indicating the most
creditworthy bond issuers and A-1 or MIG-1 indicating the most creditworthy
issuers of money market securities.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a fund's securities by credit
rating can help in gauging the risk that returns could be affected by defaults
or other credit problems.

DISTRIBUTION BY ISSUER. A breakdown of a fund's holdings by type of issuer or
type of instrument. 

EXPENSE RATIO. The percentage of a fund's average net assets used to pay its
annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

YIELD. A snapshot of a fund's interest income. The yield, expressed as a
percentage of the fund's net asset value, is based on income earned over the
past seven days and is annualized, or projected forward for the coming year.

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each fund's holdings on the last day
of the reporting period, including each security's maturity date, coupon rate or
yield to maturity at the time of purchase, and statement-date market value.
Securities are grouped and subtotaled by type of instrument (U.S. government
obligations, commercial paper, certificates of deposit, etc.). Other assets are
added to, and liabilities are subtracted from, the value of Total Investments to
calculate the fund's Net Assets. Finally, Net Assets are divided by the
outstanding shares of the fund to arrive at its share price, or Net Asset Value
(NAV) Per Share. Each fund's objective is to maintain a constant NAV of $1.00
per share.

    At the end of the Statement of Net Assets of each fund, you will find a
table displaying the composition of the fund's net assets. Virtually the entire
amount of net assets consists of Paid in Capital (money invested by
shareholders). Undistributed Net Investment Income is usually zero because the
fund distributes its net income to shareholders as a dividend each day, and
Accumulated Realized Gains (Losses) are very small because the fund seldom
realizes any significant gains or losses on sales of securities.

STATEMENT OF OPERATIONS

This Statement shows interest earned by each fund during the reporting period,
and details the operating expenses charged to each class of its shares. Expenses
directly reduce the amount of investment income available to pay to shareholders
as income dividends. This Statement also shows any Net Gain (Loss) realized on
the sale of investments, and any Unrealized Appreciation (Depreciation) on
investments during the period. For money market funds, Realized Net Gain (Loss)
should always be minimal and Unrealized Appreciation (Depreciation) should be
zero.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. Because the fund distributes its income
to shareholders each day, the amounts of Dividends from Net Investment Income
generally equal the net income earned as shown under the Operations section. The
Capital Share Transactions section shows the amount shareholders invested in the
fund, either by purchasing shares or by reinvesting distributions, and the
amounts redeemed. Dividends and Capital Share Transactions are shown separately
for each class of shares.

FINANCIAL HIGHLIGHTS

Each fund's objective is to maintain a constant NAV of $1.00 per share by
distributing all of its income and avoiding capital gains or losses. The
financial highlights table summarizes each fund's investment results and
distributions to shareholders on a per-share basis for each class of shares. The
table also presents the Total Return and shows net investment income and
expenses as percentages of average net assets for each fund or class of shares.
These data will help you assess the variability of net income returns from year
to year and how much it costs to operate the fund.

NOTES TO FINANCIAL STATEMENTS

Vanguard Money Market Funds comprises the Prime Money Market Fund, Federal Money
Market Fund, and Treasury Money Market Fund, each of which is registered under
the Investment Company Act of 1940 as a diversified open-end investment company,
or mutual fund. The Prime Money Market Fund invests in short-term debt
instruments of companies primarily operating in specific industries; the
issuers' abilities to meet their obligations may be affected by economic
developments in such industries. The Federal Money Market Fund invests in
short-term debt instruments issued by the U.S. government or its agencies and
instrumentalities. The Treasury Money Market Fund invests in short-term debt
instruments backed by the full faith and credit of the U.S. government.

A. The following significant accounting policies conform to generally accepted
accounting principles for mutual funds. The funds consistently follow such
policies in preparing their financial statements.

      1. SECURITY VALUATION: Securities are valued at amortized cost, which 
approximates market value.

      2. FEDERAL INCOME TAXES: Each fund intends to continue to qualify as a
regulated investment company and distribute all of its taxable income.
Accordingly, no provision for federal income taxes is required in the financial
statements.

      3. OTHER: Security transactions are accounted for on the date the
securities are purchased or sold. Costs used to determine realized gains
(losses) on the sale of investment securities are those of the specific
securities sold. Discounts and premiums are accreted and amortized,
respectively, to interest income over the lives of the respective securities.
Dividends from net investment income are declared daily and paid on the first
business day of the following month.

      4. REPURCHASE AGREEMENTS: Securities pledged as collateral for repurchase 
agreements are held by a custodian bank until the agreements mature. Each
agreement requires that the market value of the collateral be sufficient to
cover payments of interest and principal; however, in the event of default or
bankruptcy by the other party to the agreement, retention of the collateral may
be subject to legal proceedings.

B. The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, shareholder accounting, marketing, and distribution
services. The costs of such services are allocated to each fund under methods
approved by the Board of Trustees. Each fund has committed to provide up to
0.40% of its assets in capital contributions to Vanguard. At November 30, 1998,
the funds had contributed capital to Vanguard (included in Other Assets) of:

The funds' Trustees and officers are also Directors and officers of Vanguard.

C. The Prime Fund offers two classes of shares, the Investor Shares and the
Institutional Shares. Institutional shares are designed primarily for
institutional investors that meet certain administrative and servicing criteria
and have a minimum investment of $10 million. Investor shares are offered to all
other investors. Both classes of shares have equal rights as to assets and
earnings, except that each class bears certain class-specific expenses related
to its shareholder activity. For the year ended November 30, 1998,
class-specific expenses of the Investor Shares and Institutional Shares
represented effective annual rates of 0.22% and 0.04%, respectively, of their
average net assets. Income, expenses not attributable to a specific class, and
realized and unrealized gains and losses on investments are allocated to each
class of shares based on its relative net assets.

REPORT OF INDEPENDENT
ACCOUNTANTS 

[PHOTO]

To the Shareholders and 
Trustees of Vanguard Money Market Funds

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Prime Money Market Fund, Federal Money Market Fund and Treasury Money Market
Fund (hereafter referred to as the "Funds") at November 30, 1998, the results of
each of their operations for the year then ended, the changes in each of their
net assets for each of the two years in the period then ended and the financial
highlights for each of the periods indicated, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at November 30, 1998 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.

                              The Vanguard Group is
                             named for HMS Vanguard,
                        Admiral Horatio Nelson's flagship
                          at the Battle of the Nile on
                          August 1, 1798. Our founder,
                          John C. Bogle, chose the name
                        after reading Nelson's inspiring
                      tribute to his fleet: "Nothing could
                          withstand the squadron . . .
                       with the judgment of the captains,
                      together with their valour, and that
                        of the officers and men of every
                  description, it was absolutely irresistible."

                          Walter L. Morgan, founder of
                          Wellington Fund, the nation's
                           first balanced mutual fund
                        and forerunner of today's family
                           of some 100 Vanguard funds,
                        celebrated his 100th birthday on
                           July 23, 1998. Mr. Morgan,
                         a true investment pioneer, died
                         six weeks later on September 2.

                                Wellington Fund,
                        The Vanguard Group's oldest fund,
                         was incorporated by Mr. Morgan
                       70 years ago, on December 28, 1928.
                            The fund was named after
                             the Duke of Wellington,
                              whose forces defeated
                            Napoleon Bonaparte at the
                           Battle of Waterloo in 1815.
