                       A BRAVE NEW WORLD FOR INVESTING

With  the clarity of hindsight, we can  now see that the past two
decades  composed one of  the great cycles in  the history of the
financial markets, as reflected in the chart below.

* During the 1973-1982 decade, the nominal total returns (capital
  change plus income) of stocks and bonds averaged only about +6%
  per  year;  cash  reserves  averaged more  than  +8%  annually.
  However,  high   inflation  rates,  averaging   8.7%  annually,
  devastated these nominal results. Real returns (nominal returns
  less  the inflation rate) for  each of these  three major asset
  classes were actually negative.

* During  the  1983-1992  decade,  quite  the  opposite situation
  prevailed. Nominal returns  for stocks and bonds  were close to
  their  highest levels in  history and forged  well into double-
  digit  territory. To  make a  good investment  environment even
  better, inflation was tame  (averaging 3.8% annually), and real
  returns were solidly positive.

[A TALE OF TWO DECADES TABLE -- SEE EDGAR APPENDIX]

This  sharp contrast provides us  with perspective for the decade that 
will end  in  the year  2002. Some  investors  will fear  a recurrence  of the
returns of the first decade, while others will hope  for a recurrence of the
second; most will likely anticipate something in  between. Whatever the case,
there are two essential elements involved  in considering your investment 
program in the light of today's circumstances.

        First, the  yield of each  investment class at  the start  of a decade
has had  an important relationship  to its future  return. Yields were  low
when 1973 began,  high when 1983  began, and are again  low today. In  fact,
current income  yields are remarkably close to  the levels of 20  years ago, as
shown  in the following table.

But there  is a second important element  to consider: inflation.
It got progressively worse  during most of the first  decade, but
got progressively better in the second.

CHAIRMAN'S LETTER

DEAR SHAREHOLDER:

The decline in interest rates continued--and indeed accelerated--
during  the twelve  months ended  November 30,  1993, the  eighth
fiscal  year of the  Vanguard State Tax-Free  Funds. Lower yields
pushed the  prices of long-term tax-exempt bonds  higher, and the
net asset  values of  our Insured Long-Term  Portfolios benefited
accordingly. As rates fell, however, interest income was reduced,
with  the  most  immediate  impact  felt   in  our  Money  Market
Portfolios.

        Reflecting the  low-interest-rate  environment  that  prevailed over
the past twelve months, our Money Market Portfolios provided returns that were
modest in an absolute sense, albeit comfortably above the returns of their
respective competitive benchmarks. The total returns (capital change  plus
income) of our Insured  Long- Term Portfolios  were  exemplary, surpassing 
even the  excellent results  that we  achieved  in  our  prior  fiscal  year. 
It  is difficult  to  imagine a  more  beneficial  two-year stretch  for
investors  in  long-term  bonds.  In  any  event,  here  are  the Portfolio
highlights for the past twelve months:

* THE STATE MONEY MARKET PORTFOLIOS
  provided  total returns  of about  +2.4% .  . .  with declining
  money market rates for yet another year, Portfolio yields ended
  the period at  lower levels than where they began,  hovering in
  the area of 2.3% . . . net asset values, of course, remained at
  $1.00 per share.

* THE   STATE   INSURED  LONG-TERM   PORTFOLIOS--
  enjoyed  another outstanding year "across  the board," as each
  Portfolio  turned in  a double-digit  return  ranging from  +12% to  +13%  .  
  . current  yields  are  at  their  lowest  levels  in our  Funds' (admittedly
  rather short) history.

including per share net asset values, dividends and capital gains distributions

</TABLE>

In last year's Annual  Report, I called special attention  to the
substantial  capital component (appreciation  in net  asset value
per  share) of the total  returns on our  State Insured Long-Term
Portfolios. My  purpose in doing  so at  that time was  to advise
investors that  it seemed unreasonable to expect  a recurrence of
these capital returns in fiscal 1993. As shown in the table, this
year the role of capital  appreciation in our Portfolios' results
turned  out to be even  more dramatic, accounting  on balance for
some 50% of our total returns.

[MONTH-END YIELDS 1990-1993 CHART -- SEE EDGAR APPENDIX]

   Although my cautionary  words one year  ago could hardly  have
been   further  off   the  mark,   I  nonetheless   would  remind
shareholders that capital  returns of the magnitude shown  in the
preceding table simply  cannot be taken for granted. Indeed, with
long-term interest rates  at their lowest levels  in two decades,
now  is a perfect  opportunity to  remind investors  that, should
rates reverse  direction and  move higher, "capital  reward" will
inevitably  translate to  "capital penalty"  for each of  our six
Insured Long-Term Portfolios.

   The excellent  absolute returns for  all of our  Insured Long-
Term  Portfolios in fiscal 1993  come on top  of the double-digit
returns earned in the prior fiscal year. The chart at  the top of
the facing page illustrates the results of the Ohio Insured Long-
Term  Portfolio since its  inception in June  1990, compared with
the results of the two most appropriate available benchmarks: the
unmanaged  Lehman  Municipal  Bond  Index and  the  average  Ohio
insured  municipal  bond fund.  You can  see  that, in  our brief
history,  our returns have been nicely above those of the average
competitor and the unmanaged  Index. I should also note  that the
Ohio Money  Market Portfolio  has enjoyed solid  relative results
over the  same period,  achieving a  cumulative return of  +13.0%
versus  +12.4% for  its  average competitor  (+3.6% versus  +3.5%
annually).

* THE FISCAL YEAR IN REVIEW

Our  1993 fiscal year was the sixth consecutive year of favorable
markets--and the third consecutive year of double-digit returns--
for  long-term  bonds.  Lower  yields  drove  up  the  prices  of
municipal,  corporate, and  U.S. Treasury  bonds  alike. Treasury
bonds  registered  the largest  rate  declines  and garnered  the
greatest price appreciation, gaining some +17% for the year. Over
the  same period,  yields  on high-grade,  long-term,  tax-exempt
bonds  fell  0.70%  (70  "basis  points"),  from  6.2%  to  5.5%,
resulting in a price increase of +10%.

   Compared to the sharp decline in long-term rates over the past
twelve months, the drop in short-term tax-exempt rates was fairly
muted. From the  2.7% level  at the  outset of  the fiscal  year,
yields  on high-grade  (MIG 1)  municipal notes  fell to  2.0% in
January 1993,  climbed to 2.6% at the end of July, and closed the
year at 2.4%.

   The  consensus holds  that the  rate decline  is based  on two
fundamental  factors. First, the  U.S. economy  remains sluggish,
unable  to  provide  the  typical  post-recession  snapback  that
investors  have   come  to  expect.  Second,   and  perhaps  more
importantly, there is continuing  evidence that inflation remains
well under control. The U.S. consumer price index (CPI) increased
2.7% over the  past twelve  months, compared to  3.0% during  the
prior twelve-month period. As a result, despite the sharp decline
in  interest  rates,  "real"  yields  (nominal  yields  less  the
inflation rate) on long-term bonds remain at healthy levels.

   The  chart to the left provides a striking illustration of how
precipitous the decline in interest

<PAGE>   5



[CUMULATIVE PERFORMANCE JUNE 30, 1990 TO
 NOVEMBER 30, 1993 CHART -- SEE EDGAR APPENDIX]

rates  has been over the past four  years, with nearly all of the
decline coming during the  final three years. The yield  on high-
grade, long-term municipal  bonds fell from 7.0% on  November 30,
1989, to  5.5% on  November 30,  1993. For short-term  tax-exempt
rates, the  decline during the  same period was  more pronounced,
with the yield on  high-grade notes falling on balance  from 5.9%
to 2.4%. As  a result  of this  disparity in  rate declines,  the
"spread" of  the long rate  over the short rate  has widened from
110 basis  points at  the beginning of  the period  to 310  basis
points  at the end. This  widening reflects a  very "steep" yield
curve, allowing  fixed-income  investors to  earn  a  substantial
income  premium by extending the maturity of their bond holdings.
It should  go  without saying  that each  step out  in length  of
maturity brings with it additional price volatility.

* THE ADVANTAGE OF TAX-EXEMPT INCOME

In  each year's  Annual Report,  we present  our customary  table
illustrating  the  advantage  of  tax-exempt  investments  versus
taxable investments,  after adjusting  for the effect  of Federal
taxes at the maximum  marginal rate on income payments.  Here are
the results of the comparison at the end of fiscal 1993:

       ---------------------------------------------------------------------------
</TABLE>

Table  assumes current yields (as  of November 30,  1993) of 6.3%
for  U.S. Treasury bonds, 3.2% for Treasury bills, 5.5% for long-
term  municipals,  and   2.4%  for  short-term  municipals.   The
illustration is not intended to represent future results.

The  advantage spelled out in the table--a 45% increase in after-
tax income for the long-term investor and a 26%  increase for the
short-term investor--strongly  suggests  that investors  who  are
taxed at  the highest  marginal rates should  consider tax-exempt
alternatives for the fixed-income





                                      3
<PAGE>   6





portion of their overall investment portfolio. (I should add that
both the interest earned on our State Tax-Free Portfolios and the
interest  earned on  U.S.  Treasury obligations  are exempt  from
taxes at the state level.)

   As I noted  earlier, the  decline in yields  on U.S.  Treasury
bonds  has  been significantly  larger  than  that on  tax-exempt
bonds. This  divergence is paradoxical considering  that it comes
just as the  maximum marginal  federal tax rate  has been  raised
from  31% to 39.6%--the highest rate since 1986. This should mean
that the spread between taxable and tax-exempt rates would widen;
instead,  it has  narrowed for  long-term investors  and remained
about the same for short-term investors.

   To  be sure, even the  highest quality insured state municipal
bond cannot quite  match the creditworthiness of  a U.S. Treasury
bond, and long-term municipal bonds are usually callable after 10
years, a disadvantage not shared by Treasury securities. So,  the
yield  comparison has  a  moderate structural  bias  in favor  of
municipals. But  the yield differential illustrated  in the table
is hardly "moderate"--it is more like "day and night." Suffice it
to  say that  the  ability of  top-tax-bracket investors  to earn
substantially  more   after-tax  income  with  only   a  marginal
sacrifice  in quality is unlikely  to persist indefinitely. It is
probably fair to say that relative values in tax-exempt bonds are
as great as they have been for two decades.

* A PERSPECTIVE ON TODAY'S INTEREST RATE ENVIRONMENT

The aggregate assets of all municipal bond mutual funds now total
some $350 billion, and the funds are now among the largest buyers
and  holders of  tax-exempt  securities. While,  like all  mutual
funds, our State Insured  Tax-Free Portfolios promise  "liquidity
on  demand" to shareholders, it must be clear that providing this
liquidity depends to a degree  on an orderly liquidation  pattern
by  investors. With  the exception  of the  industry's experience
during 1987's  sharp dip in long-term bond prices, resulting from
the  upward spikes  in interest rates  in April  and May  of that
year, the  industry's handling of redemptions  has been flawless,
and  daily liquidity  has been  maintained without  impacting the
marketplace.  (Given the  very short  maturities of  money market
instruments, liquidity is  much less  of a concern  in our  State
Money Market Portfolios.)

   And yet, with rates having come down so far and so fast, there
is  always  the  risk of  a  sharp  rebound.  When that  happens,
investors who  have purchased municipal  bond funds for  the long
term should not  be concerned.  However, there appears  to be  an
active  body of short-term speculators who  move their money from
long-term  to short-term bonds at  the proverbial drop  of a hat.
You should know that at Vanguard we do our best  to exclude these
speculators from our funds,  by rigorously limiting the frequency
of inter-fund exchanges and  by refusing to accept business  from
known "market timers."

   If you are an investor who likes to speculate on interest rate
changes,  I  urge you  to move  your assets  to  one of  our many
competent competitors. If  you are an  investor who will  respond
with fright to any kind of  reversal of the past five year's rise
in bond prices,  I urge you to shorten your  maturity profile by,
for  example, moving  a  portion of  your  assets from  the  more
volatile  Insured  Long-Term  Portfolio  for your  state  to  our
corresponding Money Market Portfolio (available in all states but
New York and Florida, in which case the Money Market Portfolio of
Vanguard Municipal Bond  Fund might  be selected). If  you are  a
long-term investor--content that your needs for capital stability
(with  commensurate  income  volatility)  in  our  Money   Market
Portfolios and  for income  stability (with  commensurate capital
volatility) in our Insured  Long-Term Portfolios are being met--I
urge you, once again, to "stay the course."

* IN SUMMARY

As I write  this letter, the combined assets  of the ten Vanguard
State Tax-Free Portfolios are approaching the $8 billion mark, up
some 30% in just one year. This staggering growth is a testament,
we believe, to an ever-increasing understanding among investors


                                      4
<PAGE>   7



that, all  else being equal, costs will "carry the day." With the
yield on the average state tax-exempt bond fund at 4.3%, and with
102  of 137 state tax-exempt money market funds now yielding less
than 2.0%, costs will be an even more critical determinant of the
top-performing funds.

   This  is  precisely  the  kind of  environment  in  which  the
Vanguard  State  Tax-Free  Portfolios  should  thrive.  While the
average competitive state tax-free  portfolio charges annual fees
at the rate of 0.68% of average net assets, the expense ratio for
our Portfolios, at 0.21%, is just a fraction of this amount.  For
a money market portfolio with a gross yield of 2.0%, the expenses
of  the  average  competitor  would  consume  nearly  35% of  its
interest income; Vanguard's expenses would consume but 11%. It is
hard to imagine  that intelligent investors could be attracted to
a fund with such a built-in yield disadvantage.

   In  closing, we  believe that, whatever  the future  course of
interest  rates,  our  State  Tax-Free  Portfolios  will  provide
returns   that  generally  exceed   those  of   their  respective
competitors.

Sincerely,

A WORD ABOUT CAPITAL GAINS DISTRIBUTIONS

You  may recall that,  during the rising bond  markets of each of
the past  three years, some  of our Insured  Long-Term Portfolios
realized modest capital gains. And, it will probably not surprise
you to know that  each Portfolio realized capital gains  in 1993.
These amounts must, under Federal tax regulations, be distributed
to shareholders of our Portfolios as taxable capital gains.

   I want to emphasize  that it is  not our objective to  realize
capital gains; rather, these  gains are a by-product of  a number
of factors, including, most importantly, sharply rising municipal
bond  prices, bonds  that  are called  or  refunded, and  limited
portfolio   strategy  shifts  to   capitalize  on   the  relative
valuations of different market sectors.

       REPORT FROM THE INVESTMENT ADVISER

       STATE INSURED
       LONG-TERM PORTFOLIOS

       * TIME FOR CHANGE?

       Just one  year ago, President Clinton  was elected on a platform of
       change. Since that time, the restrictive economic impact of higher
       taxes has overshadowed the relatively quiet role played by Federal
       Reserve policy, and long-term interest rates have declined
       precipitously.  For the fiscal year ended November 30, 1993, the yield
       on  the 30-year U.S. Treasury Bond fell 1.2 percentage points (from
       7.5% to 6.3%).  During the same period, high-grade, long-term municipal
       yields fell nearly three-quarters of a percentage point, from 6.2% to
       5.5%.

            The net result was another year of good performance both for the
       State Insured Long-Term Portfolios and the bond market as a whole.  In
       light of the many successive years of above-average returns by
       longer-maturity fixed-income investments, one has to wonder how much
       longer the rally can last.

       * MUNICIPAL BONDS ARE ATTRACTIVE VERSUS TAXABLE BONDS

       While municipal bond prices have risen sharply, taxable bond prices
       have rallied even more.  High-grade tax-exempt bonds currently
       provide 86% of the yield on the 30-year U.S. Treasury bond, up
       from 82% at the beginning of the year. This "cheapening" has been due
       primarily to a huge increase in the pace of municipal bond issuance.
       Indeed, 1993 municipal supply set an all-time record of some $290
       billion--fully 25% above the previous record set just last year, and
       easily twice the volume of a typical year's issuance.

            Municipalities of all types have flooded the marketplace to
       refinance higher cost debt at today's lower yield levels. We believe
       this process has run full course, and suggest that municipal bonds
       are extremely attractive when compared to their taxable brethren. The
       case for municipal bonds is even more compelling in light of recently
       increased marginal tax rates.

       * INVESTMENT STRATEGY

       Given the current environment, the State Insured Long-Term Bond
       Portfolios are pursuing the following investment strategies:

        * CALL PROTECTION.  We continue to emphasize call protection in all
          of our longer bond portfolios.  This strategy has produced
          greater price appreciation as yields have declined. Importantly,
          it also will insulate future dividends from an abrupt decline due to
          bond calls.

        * MUNICIPAL VERSUS TREASURY. We have positioned the Portfolios to
          take advantage of the exceptionally cheap relationship of municipal
          bonds versus Treasury bonds.  This positioning has been
          accomplished by simultaneously establishing long positions in
          municipal bond futures contracts and short positions in Treasury
          bond futures contracts.  Although this strategy has slightly
          detracted from annual performance thus far, we believe it will
          produce positive results in 1994.

        * "LONG AND RIGHT." Over the past few years, the State Insured
          Long-Term Portfolios have maintained a longer maturity structure
          and consequently a higher sensitivity to changes in interest
          rates than our competitors. This strategy has served us well and
          produced good longer-term results  in a substantial bull market for
          fixed-income securities. During  the course of the past year, we
          reduced somewhat  our longer maturity structure to match that of our
          competitors, thereby "locking in" gains earned to date.


          In conclusion, the past  twelve months has been an exciting period for
       bond fund shareholders. Plummeting interest rates have translated into
       attractive performance returns on long-term, tax-exempt fixed-income
       investments. To be sure, this will be a tough standard to surpass.

                                                                     (continued)

       STATE MONEY MARKET PORTFOLIOS

       Over the past twelve months, moderate economic expansion and low
       inflation enabled the Federal Reserve Board to hold key interest rates
       steady. The last policy action taken by the Fed occurred in early
       September 1992, when it lowered the Federal funds rate to 3%.

          Despite the overall stability in short-term rates, yields on
       tax-exempt money market funds continued to decline. Plagued by a
       combination of sporadic supply and strong investor demand, yields on
       state-specific money funds deteriorated 30 basis points, from 2.2% to
       1.9%. Notwithstanding this yield decline, assets grew at a robust 14%
       rate. Strong performance versus the competition, due primarily to
       Vanguard's expense ratio advantage, enabled our money market funds to
       capture a large percentage of these assets.

          The volume of new issue supply differed greatly among the various
       state-specific funds. Recessionary and fiscal stress, which has
       persisted in California, forced many of its municipalities to finance
       their cash needs with short-term debt. As a result, July and August
       brought a flood of supply in California tax-exempt paper. At the
       opposite end of the spectrum was New Jersey, where diminished supply was
       attributable primarily to relatively low long-term interest rates. The
       many municipalities that previously issued short-term notes took
       advantage of these low rates by issuing long-term bonds instead.

          Looking forward, net new issuance in the first quarter of fiscal year
       1994 is expected to remain light.  Poised for this anticipated drought
       in supply, the Vanguard State Tax-Free Money Market Portfolios are
       currently targeting a minimum average weighted maturity of 75 days.
       Beyond the first quarter we will proceed with caution, as any signs of
       increased inflation may prompt the Federal Reserve Board to raise
       short-term interest rates.

       NOTES TO FINANCIAL STATEMENTS

       Vanguard Ohio Tax-Free Fund is registered under the Investment Company
       Act of 1940 as an open-end investment company and consists of the
       Insured Long-Term and Money Market Portfolios. Each Portfolio invests in
       debt instruments of municipal issuers whose ability to meet their
       obligations may be affected by economic and political developments in
       the State of Ohio.

       *  A. The following significant accounting policies are in conformity
          with generally accepted accounting principles for investment 
          companies.  Such policies are consistently followed by the Fund in 
          the preparation of financial statements.

          1. SECURITY VALUATION: Money Market Portfolio: investment securities
             are valued at amortized cost which approximates market value.
             Insured Long-Term Portfolio: municipal bonds are valued utilizing
             primarily the latest bid prices or, if bid prices are not
             available, on the basis of valuations based on a matrix system
             (which considers such factors as security prices, yields,
             maturities and ratings), both as furnished by an independent
             pricing service.

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

          3. FUTURES: The Insured Long-Term Portfolio may utilize futures
             contracts to a limited extent. The primary risks associated with
             the use of futures contracts are imperfect correlation between the
             change in market value of the bonds held by the Portfolio and the
             prices of futures contracts, and the possibility of an illiquid
             market. Futures contracts are valued based upon their quoted daily
             settlement prices. Fluctuations in the value of futures contracts
             are recorded as unrealized appreciation (depreciation) until
             terminated at which time realized gains (losses) are recognized.
             Unrealized appreciation (depreciation) related to open futures
             contracts is required to be treated as realized gain (loss) for
             Federal income tax purposes.

          4. DISTRIBUTIONS: Distributions from net investment income are
             declared on a daily basis payable on the first business day of the
             following month. Annual distributions from realized gains, if any,
             are recorded on the ex-dividend date. Capital gain distributions
             are determined on a tax basis and may differ from realized capital
             gains for financial reporting purposes due to differences in the
             timing of realization of gains.

          5. OTHER: Security transactions are accounted for on the date the
             securities are purchased or sold. Costs used in determining
             realized gains and losses on the sale of investment securities are
             those of specific securities sold. Premiums and original issue
             discounts are amortized and accreted, respectively, to interest
             income over the lives of the respective securities.

       *  B. The Vanguard Group, Inc. furnishes at cost investment
          advisory, corporate management, administrative, marketing and
          distribution services. The costs of such services are allocated to
          the Fund under methods approved by the Board of Trustees. The Fund
          has contributed capital of $48,000 to Vanguard (included in Other
          Assets), representing .2% of Vanguard's capitalization. The Fund's
          officers and trustees are also officers and directors of Vanguard.

       NOTES TO FINANCIAL STATEMENTS (continued)

      * C.  During the year ended November 30, 1993, the Insured
        Long-Term Portfolio made purchases of $70,217,000 and sales of
        $13,075,000 of investment securities other than temporary cash
        investments.

        At November 30, 1993, unrealized appreciation of investment
        securities  of the Insured Long-Term Portfolio for financial 
        reporting and Federal income tax purposes aggregated $10,493,000,
        of which $10,671,000 related to appreciated securities and $178,000
        related to depreciated securities.

      * D.  At November 30, 1993, the Insured Long-Term Portfolio had
        long positions in Municipal Bond Index futures contracts expiring
        through March 1994, with an aggregate settlement value and net
        unrealized depreciation of $3,041,000 and $19,000, respectively.
        The aggregate settlement value and net unrealized appreciation
        related to short positions in U.S. Treasury Bond and U.S. Treasury
        Note futures contracts expiring through March 1994, were
        $16,563,000 and $158,000, respectively. The market value of
        securities deposited as initial margin for open futures contracts
        was $563,000.

       REPORT OF INDEPENDENT ACCOUNTANTS

       To the Shareholders and Board of Trustees
       Vanguard Ohio Tax-Free Fund

       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 the Insured Long-Term Portfolio and the Money
       Market Portfolio (constituting the Vanguard Ohio Tax-Free Fund,
       hereafter referred to as the "Fund") at November 30, 1993, the results
       of each of their operations, the changes in each of their net assets and
       the financial highlights for each of the respective periods presented,
       in conformity with generally accepted accounting principles. These
       financial statements and financial highlights (hereafter referred to as
       "financial statements") are the responsibility of the Fund's 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 by correspondence with the custodian and
       brokers and the application of alternative auditing procedures where
       confirmations  from brokers were not received, provide a reasonable
       basis for the opinion expressed above.

       (continued inside front cover)

       toward those of the 1970s. However, the current level of inflation
       suggests that future real returns may prove to be satisfactory. Looking
       forward, the main risks to the investor are two: (1) that yields on
       financial assets will rise sharply, reducing the prices of stocks and
       bonds alike; and (2) that inflation, presently at moderate levels, will
       accelerate.

       SOME COURSES OF ACTION

       What, if any, present action should be taken by investors to deal with
       these two major risks? Should your allocation of assets among stock
       funds, bond funds, and money market funds be adjusted? Here are some
       reasonable courses of action to consider:

       *  For long-term investors who have built a substantial balanced
            portfolio of stock, bond, and money market funds, stay the course.
            Even if withdrawing from the stock market proves to be justified, 
            the next decision--when to return--will one day be required. 
            "Being right twice" is no mean challenge.

       *  For long-term investors gradually accumulating assets for, say,
            retirement, stay your present course.  Continue to invest regularly.
            By doing so, you buy more shares of a mutual fund when its price
            falls, and fewer shares when its price rises, virtually assuring a
            reasonable average cost.

       *  For risk-averse investors who are highly confident that stock prices
            are "too high," make only marginal-- not "all or nothing"--changes 
            in your portfolio balance. Given the perils of predicting the 
            future, any changes should be limited to, say, 15 percentage 
            points. That is, if your normal portfolio allocation is 60% in 
            stock funds, it might be reduced to 45%; if 85%, to 70%.

       *  For investors who simply must have more income, never lose sight of
            the added principal risk involved in shifting from money market 
            funds to bond funds. Long-term bond funds provide a generous and 
            durable income stream, but their prices are highly volatile. 
            Short-term and intermediate-term bond funds offer a "middle way" 
            of increasing income with more modest risk to principal.

       *  For investors who are tempted to find an "easy way" to higher
            returns, never forget that risk and reward go hand in hand.
            Precipitously replacing certificates of deposit with broad-based
            common stock funds verges on the irrational. Funds investing in 
            other securities markets--emerging nations, international stocks 
            and bonds, and small U.S. companies--carry their own special risks. 
            Generally, limit such alternative investments to, say, 20% of your 
            total portfolio.

       For all investors, be prepared for sharp interim swings in stock and
       bond prices. The central tenet of investing is "prices fluctuate," and
       sensible long-term investors simply must take such fluctuations in their
       stride. Successful investing is as much a function of your own
       discipline and equanimity as it is of the returns available in the
       securities markets.

       THREE ESSENTIAL PRINCIPLES

       As we confront the brave new world of investing that may well lie ahead
       in the coming decade--and it is important to think in decade-length
       terms--we would underscore three caveats:

       1.   Have "rational expectations" for future returns. At prices
            prevailing today, it seems highly unlikely that the returns enjoyed
            by investors in the past decade will be repeated in the coming
            decade.

       2.   Maintain a balanced portfolio consisting of stock, bond, and money
            market funds. Each asset class has its own risk and reward
            characteristics. By allocating your resources among the three asset
            classes according to your own requirements, you can build a
            portfolio providing appropriate elements of capital appreciation,
            capital conservation, and current income.

       3.   In balancing risk against reward, be sure to consider cost. Many
            mutual funds carry hefty sales charges or high expense ratios, or
            both. Other factors held equal, expenses reduce returns, dollar for
            dollar.  Put another way, high-cost funds must select investments
            with higher prospective gross returns-- whichentail higher
            risks--to match the net returns earned by low-cost funds.

       This brief Annual Report essay can provide only an elementary look at
       the challenges investors face today.  History can give us perspective,
       but it cannot give us performance. Famed British economist Lord Keynes
       had it right when he said, "the inevitable never happens. It is the
       unexpected always."
