                  THE VANGUARD VOYAGE . . . STAYING THE COURSE

WE ARE PRESENTLY OBSERVING TWO MILESTONES IN OUR HISTORY: (1) THE 20TH
ANNIVERSARY OF THE VANGUARD GROUP; AND (2) THE 65TH ANNIVERSARY YEAR OF
WELLINGTON FUND, THE OLDEST MUTUAL FUND ASSOCIATED WITH VANGUARD. WE CELEBRATE
THESE TWO EVENTS SINCE THEY HAVE INDELIBLY ALTERED THE MUTUAL FUND INDUSTRY--IN
OUR VIEW, FOR THE BETTER.

Wellington Fund--a pioneer in the mutual fund industry--began operations on
June 30, 1929. Its first fifteen years were a struggle for survival in an
industry that was shaken to its roots by the Great Crash of 1929-1933. From an
initial base of $100,000, Wellington's assets had grown to but $27 million by
the end of World War II. The Vanguard Group was founded on September 24, 1974.
Soon thereafter, we assumed responsibility for the management of Wellington
Fund and ten associated funds, with assets aggregating $1.4 billion.

         The years that followed the founding of The Vanguard Group were marked
by exceptional growth. Today, Wellington Fund, with assets of nearly $9
billion, remains one of the largest mutual funds in the nation. And Vanguard,
now managing 85 mutual fund portfolios, is entrusted with assets of $134
billion, and ranks as the second largest fund complex in the world.

         Our durability in an era of change--and our longevity in an era of
challenge--didn't "just happen." What brought us to where we are today is what
we were when we began. Put another way, we set our original investment course
based on sound principles, and our corporate course based on a single focus:
serving solely the interests of our Fund shareholders.

FOUNDING INVESTMENT PRINCIPLES

The founding investment principles of Wellington Fund were, above all,
conservative. The Fund provided a broadly diversified portfolio at a time when
holding individual securities was the conventional strategy. It incurred no
debt in an era of high leverage that would soon come back to haunt less
cautious investors. And it was a "balanced" fund--in fact, Wellington is
America's oldest balanced fund--with holdings from each of the three basic
financial asset classes: cash reserves, bonds, and common stocks. In short,
Wellington Fund was a staid investment in an era of stock speculation that was
to become, almost within moments, an era of conservatism.

         For Vanguard, these investment principles endure. "Balance" is still
our watchword, because the three basic financial asset classes have
different--and usually countervailing--investment characteristics. When it
began, Wellington Fund provided a balanced program in a single investment; in
1994, such a balance is often achieved by a combination of Vanguard money
market, bond, and stock funds.

         "Conservatism," too, remains our standard. Over the years, we have
tried to maintain the discipline to eschew offering funds that lack sound
financial principles, often based on marketplace fads that could not--and did
not--endure. Our conservatism applies not only to the funds we offer, but to
the instruments in which they invest. For example, we have steered clear of
exotic derivative securities with unpredictable investment characteristics. Too
many fund managers have been taken in by these highly risky instruments, and
their shareholders have paid a heavy price--except in cases where the manager
has "made the fund whole," when to do otherwise would have shocked investors
and impaired their confidence in the fund complex.

         Speculation, it seems, comes and goes, albeit in different guises. But
the investment principles to which we have adhered since Wellington Fund began
in 1929 remain firm:

*  We offer Funds with sound and durable investment objectives, designed for
     long-term investors.

                               CHAIRMAN'S LETTER

DEAR SHAREHOLDER:

The 1994 fiscal year for Vanguard State Tax-Free Fund, which ended on November
30, 1994, was the most difficult year for bonds since the Fund's inception some
eight years ago, in April 1986. A persistent rise in long-term interest rates
during the twelve-month period sharply reduced the prices of long-term
tax-exempt bonds, and the net asset values of our Insured Long-Term Portfolios
declined accordingly. Rates also increased in the short-term arena, to the
substantial benefit of our Money Market Portfolios, which saw sharply higher
income yields during the year.

         In each of our Money Market Portfolios and our Insured Long-Term
Portfolios, our returns exceeded the results of competitive funds with similar
objectives. The detailed fiscal year results for each of our State Tax-Free
Portfolios, including per share net asset values, dividends and capital gains
distributions for the year, as well as current yields, are presented in a table
at the conclusion of this letter.

         Over the past twelve months, the STATE MONEY MARKET PORTFOLIOS
provided total returns in the area of +2.6%. As expected, net asset values
remained at $1.00 per share. Yields at the end of the fiscal year were
generally about 50% higher than they were at the beginning of the year, as
shown in the following table:

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

These yields, of course, reflect income that is entirely exempt both from
Federal income taxes and from state and local taxes in the respective states. I
would reemphasize that in each case our yields exceed those available on
comparable state money market portfolios as a group. Indeed, our yield
advantage has persisted with remarkable regularity, year in and year out, such
that the longer-term returns of our Money Market Portfolios have nicely
exceeded the returns of their peer groups. Specifically, the California Money
Market Portfolio has earned an average annual total return of +4.2% since its
inception in June 1987, compared to +3.9% for the average California money
market fund.

         The STATE INSURED LONG-TERM PORTFOLIOS suffered through a challenging
year of rising rates, resulting in negative total returns (capital change plus
income) ranging from -5.4% to -6.4%. The good news is that current yields are
considerably more generous than they were one year ago, having risen by an
average of 1.5 percentage points (150 basis points).

         In contrast to a year ago, when declining interest rates resulted in a
solid positive capital contribution (in the area of 6%) to our Insured
Long-Term Portfolios' total returns, this year the contribution from capital
return has been decidedly negative.  The table on the following page summarizes
the components of return for each of our State Insured Long-Term Portfolios
over the past twelve months. If there is a better example of the "two way
street" of interest rate sensitivity, I am not sure that I have seen it.

                                                                     (continued)

Note: The California Insured Intermediate-Term Portfolio began operations on
March 4, 1994. The Portfolio's returns since inception were: Income +3.4%;
Capital -3.6%; Total -0.2%.

In last year's letter, speaking about the remarkable capital returns that had
redounded to long-term bond investors over the prior two years, I cautioned
that "capital returns of the magnitude shown simply cannot be taken for
granted," adding 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." That capital penalty has surely come to pass.

         Despite a difficult 1994, the long-term returns of each of our Insured
Long-Term Portfolios remain exemplary, particularly when considered in the
context of what we would regard as our two most appropriate benchmarks: the
unmanaged Lehman Municipal Bond Index and the average competitive fund in each
respective state category. The chart above shows the cumulative returns earned
by the California Insured Long-Term Portfolio since its inception in April
1986, compared with each of these benchmarks.

         You can see in the chart that the Portfolio achieved a nice margin
over the average California insured municipal fund, but fell a bit short of the
unmanaged Lehman Municipal Bond Index. This Index, I would remind you,
represents a challenging hurdle for all state tax-free funds, existing, as it
does, outside of the "real world" of operating expenses and transaction costs.
Given that transaction costs in the bond market are normally quite substantial,
our ability to maintain only a modest long-term shortfall is exceptional.

[FIGURE 3]

THE FISCAL YEAR IN REVIEW

The declining interest rate environment that had persisted with striking
consistency since October 1987 came to an end in mid-October 1993. By November
30, 1993, the yield on the long-term U.S. Treasury bond had fallen to 6.3%; by
the end of the Fund's fiscal year on November 30, 1994, the long Treasury yield
had jumped back to the 8.0% level. In all, the prices of long-term U.S.
Treasury bonds fell nearly -20% over the fiscal period. In the short-term
arena, the yield on the U.S. Treasury bill rose from 3.2% to 5.8% over the same
period. Because of the bill's short maturity, its price remained virtually flat
during the entire period.

         A primary cause of the interest rate rise was investor fears about a
resurgence of inflation. So far, at least, the U.S.  Consumer Price Index gives
little evidence of it. The CPI has risen just 2.7% over the past twelve months,
although more sensitive indicators--such as commodity prices and producer
prices--have been rising at higher rates.

         In an effort to quell inflationary fears, the Federal Reserve has
acted to "tighten" the money supply in order to slow economic growth and rein
in potential future inflation. Fully six rate increases--in February, March,
April, May, August, and again in November--combined to raise the federal funds
rate (at which banks borrow from one another) from 3.00% to 5.50%. Still, the
specter of inflation remains, and further rate increases may well lie in
prospect.

         Yields on long-term municipal bonds followed the lead of U.S. Treasury
bonds, although the prices of long municipals provided slightly better
resistance than their taxable cousins to the overall decline in the bond
market. This resistance was based largely on the fact that tax-exempt bonds
began the fiscal year with yields that were extremely attractive relative to
taxable bonds. Indeed, as I mentioned a year ago in our Annual Report for
fiscal 1993, "relative values in tax-exempt bonds are as great on a sustained
basis as they have been for two decades." The result was that municipal bond
prices pretty much held their own through January, declined slightly less than
long Treasuries through the end of August, only to fall more sharply in the
final months of the Fund's fiscal year. On balance, for the full period, the
yield on high-grade, 30-year tax-exempt bonds rose from 5.5% to 6.9%, reflected
in a price decline of about -18%.

         The chart to the left shows the changing pattern of long-term and
short-term tax-exempt yields during our past five fiscal years. It provides
some perspective on the recent increase in yields, which, on the long-term
side, have merely returned to their level in mid-1991, about the same as the
yield level at the beginning of 1990. The 3.8% yield on short-term tax-exempt
notes is now approximately at the level reached in late 1991, but is well below
the 5.8% yield that prevailed when 1990 began.

         The interplay of short-term and long-term rates has resulted in
dramatic changes over time in the yield "spread" (the difference between the
two yields, as shown in the lower chart). At the start of the period, the
spread amounted to only 110 "basis points" (1.1%) with 30-year municipal bonds
yielding 7.0% and 90-day notes yielding 5.9%. By early 1992 the





                                       3
<PAGE>   6
spread had risen to nearly 400 basis points, and investors who decided to
choose short-term notes over long-term bonds had to relinquish nearly
two-thirds of their yield. Today, the spread has narrowed to about 300 basis
points, but fixed-income investors who are willing to extend the maturity of
their bond holdings still earn a solid premium in return for the additional
price volatility that they incur.

TAX-EXEMPT VERSUS TAXABLE YIELDS

One of the (too often) unsung advantages of tax-exempt income is the sharp
increase in spendable income compared to the income that would be garnered,
after taxes, on a taxable bond. In the lower rate environment of a year ago, as
I mentioned earlier in this letter, this advantage--for investors in the
highest marginal Federal tax bracket (now 39.6%)--was well above historical
norms, with tax-exempt securities providing net spendable income 45% higher
than that available on taxable U.S. Treasury bonds, and 26% higher than that
available on U.S. Treasury bills.

         One year later, this "spread" remains virtually unchanged on the
long-term side (a +44% premium) but has been more than halved on the short-term
side (a +9% premium). This table presents a comparison of the income earned on
tax-exempt and taxable securities as of November 30, 1994, assuming a $100,000
investment.

</TABLE>

Table assumes current yields (as of November 30, 1994) of 8.0% for U.S.
Treasury bonds, 5.8% for U.S. Treasury bills, 6.9% for long- term municipals,
and 3.8% for short-term municipals. The illustration is not intended to
represent future results.

The table provides a clear illustration of the yield improvement available
today to an investor in the top tax bracket. Of course, the comparison is
hardly perfect, since the "full faith and credit" of the U.S. Treasury remains
peerless, while municipal bonds engender some degree of risk. Perhaps nothing
could have made this risk clearer than the recent debacle in Orange County,
California, in which an investment pool managed by the County suffered huge
losses resulting from its leveraged strategy and derivative securities
holdings. This event serves as an important reminder that "state-specific"
portfolios engender an additional level of risk due to their highly
concentrated investments in particular economic regions.

         The Orange County bankruptcy reinforces the substantial value of
private portfolio insurance, which is provided--by high-quality insurance
companies--for virtually all of the bonds held in our Insured Portfolios. This
insurance, in effect, guarantees the full payment of annual income and, at
maturity, principal for the municipal bonds that we hold. (It does not, of
course, protect against price volatility.) The result is that each of our
Insured Long-Term Portfolios carries an implied average quality rating of
Aaa--the highest rating accorded by Moody's Investor Services. This insurance
provides credit quality enhancement that virtually eliminates the extra risk
that would otherwise be engendered by the concentration of investments that is
inevitably part and parcel of investing in single-state municipal bond funds.
We believe such protection is critical.

         Portfolio insurance is generally not available for money market
portfolios, although the same state-specific risks exist.  In the absence of
portfolio insurance, our professional money managers must be even more diligent
in their scrutiny of the credit quality of our portfolio holdings. Their
efforts here include purchasing as many high-quality and "credit-enhanced"
securities as they can. The enhancements for these securities consist of
irrevocable letters of credit from high-quality banks guaranteeing each
issuer's timely payments of principal and interest. This credit support, in
conjunction with our diligent credit analysis, has earned each of the holdings
in our Money Market Portfolios Moody's highest quality rating (or the
equivalent) for shorter-term instruments. As far as we know, our Portfolios are
unsurpassed with respect to credit quality by any competitor.

         On this point, I would stress that no state money market portfolio is
exempt from credit and





                                       4
<PAGE>   7
maturity risk. That is to say, there is no principal guarantee such as that
provided through bank savings accounts and certificates of deposit insured by
the Federal Deposit Insurance Corporation. However, we believe that the $1.00
net asset value will be preserved by state money market funds that maintain
diligent credit analysis, secure letters of credit to the degree possible, and
maintain their average portfolio maturities within the statutory maximum of 90
days.

LOOKING AHEAD

A year ago in my 1993 letter to shareholders, I cautioned that "with rates
having come down so far and so fast, there is always the risk of a sharp
rebound." That risk "came home to roost" during fiscal 1994. However, I believe
that during fiscal 1995 the probabilities now favor greater stability in
long-term tax-exempt rates, and somewhat higher short-term rates. While there
are some recent signals of higher inflation in the economy, it would not be
unusual if the financial markets' expectations are already, at least in part,
manifested in higher yields.

         Whatever the future course of interest rates, I urge you to consider
the risk-reward pattern of your investment in the Vanguard State Tax-Free Fund
in terms of your own needs and circumstances. In our Insured Long-Term
Portfolios, that means balancing the need for income stability with a
commensurate level of principal volatility. Our Money Market Portfolios seek to
maintain a $1.00 per share net asset value, but this capital stability comes at
the expense of substantial income volatility.

         In the final analysis, the best course of action is almost always to
"stay the course" with the long-term objectives that you have established. We,
too, intend to stay the course with the consistent objectives and policies that
we have established for our Portfolios. In doing so, we are confident that the
Vanguard State Tax-Free Portfolios will continue to provide returns that
generally exceed those of their respective competitors.

         In a very real sense, this is no idle boast, since our durable cost
advantage gives us a "leg up" in performance before the year has even begun.
Indeed, while the average competitive state tax-free fund charges annual fees
at the rate of 0.78% of average net assets, the expense ratio for the Vanguard
State Tax-Free Portfolios, at 0.20%, is only about one-quarter of this amount.
In the case of a municipal money market portfolio earning a current gross yield
of, say, 3.8%, the expenses for the average state tax-free fund would consume
about 20% of their income; Vanguard's expenses, on the other hand, would
consume but 5%. This remarkable income advantage--available with no sacrifice
whatsoever in credit quality--is there for the taking.

         I look forward to writing to you again six months hence.

Sincerely,

/s/ JOHN C. BOGLE

SPECIAL NOTICE TO SHAREHOLDERS OF VANGUARD CALIFORNIA TAX-FREE FUND
In case you missed my letter of December 14, 1994, I want to take this
opportunity to assure you again that the creditworthiness of shareholder
investments in the Vanguard California Money Market, Insured Intermediate-Term,
and Insured Long-Term Portfolios has been completely unimpacted by the
bankruptcy of Orange County, California. Indeed, our three Portfolios have no
investments whatsoever in the Orange County investment pool, nor do they own
any direct investments in Orange County. Given that the credit quality in our
Vanguard California Tax-Free Portfolios remains exceptionally high, it seems to
us that the best advice would be to "stay the course" and focus on long-term
objectives.

                       REPORT FROM THE INVESTMENT ADVISER

STATE INSURED LONG-TERM PORTFOLIOS

LOOK TO THE LONG TERM

It has been a volatile fiscal year for fixed-income investors. The economy
continued down the path of robust expansion, raising fears of a pick-up in
inflation and resulting in a broadbased decline in bond prices. For example,
the Bond Buyer 40 Municipal Bond Index lost -18% of its principal value over
the period as its yield rose from 5.7% to 7.2%.

         Considering this hostile economic environment, the State Insured
Long-Term Portfolios performed somewhat better than one might expect. On a
total return basis, each Portfolio performed competitively relative to similar
long-term bond funds. It is particularly important in difficult markets to
remain focused on long-term objectives. While share price volatility is far
easier to endure when prices rise than when they fall, the long-term reward of
a period of falling prices is ultimately a higher and more durable level of
tax-exempt income.

LIQUIDITY "CRISIS"

Municipal bonds fell sharply in price during the spring, leveled off briefly
during the early summer, and then resumed falling sharply after August.
Shareholder redemptions created periods of distressed municipal bond fund
selling; for many portfolios, maintaining liquidity was a key factor in
weathering the downturn. Our Portfolios carry a high percentage of cash
reserves (8%-10%) to meet shareholder transactions, a policy which proved
especially helpful during the recent price declines. At no time were the State
Insured Long-Term Portfolios forced to sell securities at "distressed" levels.

         On the plus side, the higher yields in the marketplace have greatly
reduced the issuance of new municipal bonds. The total issuance of tax-exempt
securities has declined 37% during the fiscal year. Rising yields increased
municipal issuers' cost of funds, eliminating the economic rationale for
refundings that bloated supply last year. Other factors held equal, the drop in
new supply enhances the value of existing tax-exempt securities, particularly
in higher tax states where investor demand is greater.

PURSUING THE DIVIDEND

As we mentioned in our last Semi-Annual Report, a reduction in average maturity
prior to the recent bear market enhanced our relative fund performance. The
State Insured Long-Term Portfolios focused on the slightly lower-yielding but
less volatile securities maturing in the 15- to 20-year range. This strategy
provided a moderate amount of insulation as bond prices fell. Over the next six
months, the Portfolios will pursue 25- to 30-year securities, effecting a
gradual extension of average maturity to a more normal historical range. The
commensurate benefit will be an anticipated increase in dividend, as current
yields on longer securities have reached substantially higher levels.

         Looking forward at year end, various market sources estimate that
anywhere from $45 to $60 billion in proceeds will be received by tax-exempt
participants by January 1, 1995. Barring a significant increase in new
issuance, this bodes well for adequate liquidity and should continue to provide
more attractive returns for municipal bonds than their taxable brethren.

STATE MONEY MARKET PORTFOLIOS

WEATHERING THE STORM . . .

The fiscal year can be characterized as one of protracted economic strength. In
an attempt to curb inflation and target a moderate economic growth rate, the
Federal Reserve Board tightened money supply. During 1994, the Federal Reserve
was forced to raise the Federal funds rate (the rate banks charge each other
for overnight loans) six times, for a total increase of 2.50%. The most recent
change occurred on November 15, when the Fed increased rates 0.75%, the largest
single move by the Fed since 1981. The markets reacted accordingly, with yields
on 1-year U.S. Treasury bills rising 3.3 percentage points over the fiscal
year, to 6.9%, and yields on comparable 1-year municipal notes rising 2.1
percentage points, to 4.5%.

         The relative underperformance of municipal versus taxable yields can
be attributed to the dwindling supply of short-term municipal securities. The





                                       8
<PAGE>   11
reduction was a result of municipalities extending issuance beyond one year,
and economic strength reducing the amount of borrowing necessary to finance
their cash needs. This filtered down to the fund level, as yields on state
tax-exempt money market funds increased a mere 1.0% over the fiscal year, while
taxable money fund yields increased 2.0%. For investors in lower tax brackets,
this differential meant that taxable money market funds became a viable
alternative.

         The Vanguard State Tax-Free Money Market Portfolios were prepared for
the rise in interest rates early in the year, as we positioned average weighted
maturities in a bearish range of 45-60 days. This strategy enabled us to take
advantage of rising rates while further assuring our $1.00 net asset value. Our
low expense ratios also helped us to outperform our competitors on a net yield
basis, despite the fact that many of them continue to inflate their gross
yields through quality differentials and securities subject to the alternative
minimum tax (AMT).

HISTORICAL EVENT???

Much has been written this past year about the risks of "derivative securities"
in taxable money market funds. Most notably, Community Banker's U.S. Government
Money Market Fund went down in history as being the first money fund to "break
the buck." The fund sacrificed its net asset value in exchange for higher
returns by investing in certain types of exotic and inappropriate derivative
securities. While it is true that some derivatives can be dangerous when used
inappropriately, not all derivatives are "evil." In fact, certain derivatives
can be used safely and may even improve the total quality of one's portfolio.

         The definition of a derivative (a security whose return is derived
from another security) is broad, and encompasses instruments that are "exotic"
as well as "plain vanilla." The Vanguard State Tax-Free Money Market Portfolios
do invest in securities which fall under the derivative definitional
"umbrella," but those securities do not even remotely resemble the exotic
instruments used in the now defunct Community Banker's Fund. The derivative
structures held in our Portfolios are floating rate or "put" securities, with
minimum ratings of AA or better. In addition, all of our derivatives have
coupons that reset frequently to ensure that their market prices remain close
to par (100), and they contain the option to tender or sell them at par (100).
These securities, more commonly referred to as tender option bonds, are
designed to imitate the same characteristics of non-derivative variable rate
securities. The indexes used to determine the coupon reset are the same as
those used to determine non-derivative variable rate securities.

         In contrast, the derivatives responsible for the recent taxable money
fund problems utilized indexes not directly related to short-term money market
rates. This is a dangerous game to play, particularly in the rising interest
rate environment experienced in 1994.  The U.S. Securities and Exchange
Commission (SEC) has clearly outlined the types of derivative securities that
are inappropriate for money market funds. We affirm to our investors that at no
time has any Vanguard Portfolio invested in securities deemed inappropriate by
the SEC.

         It is unfortunate that all derivatives are being branded as
speculative, when indeed many are used to enhance the overall quality of a
portfolio. Unlike Vanguard, some money market funds may engage in investments
that fail to adhere to conservative guidelines. Consequently, investors should
remember that there is no such thing as a "free lunch." When money market funds
are offering yields too good to be true, they probably are too good to be true,
unless a fund has the advantage of low expenses. We have this advantage. Our
extremely low expense ratios permit us to take and maintain the "high ground"
with respect to both liquidity and quality.

                         NOTES TO FINANCIAL STATEMENTS

Vanguard California 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, Insured Intermediate-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 California.

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
         stated at amortized cost which approximates market value. Other
         Portfolios: 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 and Insured Intermediate-Term
         Portfolios utilize Municipal Bond Index, U.S. Treasury Bond, and U.S.
         Treasury Note futures contracts to a limited extent, with the
         objectives of enhancing returns, managing





                                       21

                   NOTES TO FINANCIAL STATEMENTS (continued)
                                                  
         interest rate risk, maintaining liquidity, diversifying credit risk
         and minimizing transaction costs. The Portfolios may purchase futures
         contracts instead of municipal bonds when futures contracts are
         believed to be priced more attractively than municipal bonds. The
         Portfolios may also seek to take advantage of price differences among
         bond market sectors by simultaneously buying futures (or bonds) of one
         market sector and selling futures (or bonds) of another sector.
         Futures contracts may also be used to simulate a fully invested
         position in the underlying bonds while maintaining a cash balance for
         liquidity.

         The primary risks associated with the use of futures contracts are
         imperfect correlation between changes in market values of bonds held
         by the Portfolios 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 values
         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. At November 30, 1994, the Fund had contributed capital
aggregating $321,000 to Vanguard (included in Other Assets), representing 1.6%
of Vanguard's capitalization. The Fund's officers and trustees are also
officers and directors of Vanguard.  

The Fund's investment advisers may direct certain new issue portfolio
trades, subject to obtaining the best price and execution, to underwriters who
have agreed to rebate or credit to the Fund a portion of the underwriting fees
generated. Such rebates or credits are used solely to reduce the Fund's
administrative expenses. For the year ended November 30, 1994, directed
brokerage arrangements reduced expenses of the Insured Long-Term Portfolio by
$241,000 (an annual rate of .03 of 1% of average net assets).

C.       During the period ended November 30, 1994, purchases and sales of
investment securities other than temporary cash investments were:

At November 30, 1994, the aggregate settlement value of the Insured Long-Term
Portfolio's long positions in Municipal Bond Index futures contracts expiring
through March 1995, and the market value of securities deposited as initial
margin for open futures contracts were $41,189,000 and $2,887,000,
respectively. Net unrealized depreciation on open futures contracts of $803,000
was required to be treated as a realized loss for Federal income tax purposes,
and accordingly was included in the Insured Long-Term Portfolio's capital loss
carryforward.


                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Trustees
Vanguard California 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, the Insured Intermediate-Term Portfolio and
the Money Market Portfolio (constituting the Vanguard California Tax-Free Fund,
hereafter referred to as the "Fund") at November 30, 1994, 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 re quire 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.

                  THE VANGUARD VOYAGE . . . STAYING THE COURSE

(continued from inside front cover)

*  We set specific standards for each Fund's investment policies and
     principles.

*  We adhere to the highest standards of investment quality, consistent with
     each Fund's objectives.

*  We offer candor in our Fund descriptions (including full disclosure of risk)
     to prospective investors, and in our description to shareholders of each
     Fund's success (or, sometimes, lack of the same).

These principles make at least as much sense today as they did in 1929, perhaps
even more. For we live in an era when many fund organizations have become
asset-gathering machines, capitalizing on past performance that is unrepeatable
and investment fads that today, as yesterday, will come and go. The new
marketing policy is too often "if investors want it, we'll sell it to them."
But our principle remains "if it makes sound investment sense, we'll offer it,
even if it takes years to attract substantial assets."

FOUNDING CORPORATE VALUES

With the founding of The Vanguard Group in 1974, a new concept of values was
brought to bear on mutual fund management. Unlike other fund organizations,
Vanguard alone is structured to serve only its Funds' shareholders. Vanguard's
corporate structure places not the fund management company, but the fund
shareholders, "at the top" of the organizational chart. Vanguard Fund
shareholders are literally the owners of the firm and are entitled to all of
the benefits that, at other fund firms, accrue to the owners of the management
company.

         Because of this unique structure, Vanguard has become best known for
its low costs, which we believe are just as essential a consideration in
investing in mutual funds as risk potential and total return. We call this
relationship between risk, return, and cost the "eternal triangle" of mutual
fund investing.

         We take special pride in our position as (by far) the lowest-cost
provider of financial services in the world. Under our "no-load" offering
structure, shareholders begin their Vanguard investment program with $1,000 of
assets (not, say, $950) for each $1,000 investment. Then, under our "at-cost"
operating structure, each $1,000 is managed for only about $3 per year; our
competitors may charge three, four, or even five times that amount.

         In all, Vanguard has distinguished itself by providing Funds with
sound and durable goals to investors with long-term time horizons, and doing so
at the fairest financial terms available. We believe that the unique Vanguard
structure "promotes a healthy and viable mutual fund complex within which each
Fund can better prosper; enables the Funds to realize substantial savings from
advisory fee reductions; promotes savings from economies of scale; and provides
the Funds with direct and conflict-free control over distribution functions."
We are not alone in this belief. Indeed, the quotation is taken verbatim from
the unanimous decision of the U.S. Securities and Exchange Commission when, in
1981, it approved our application for the structure under which we operate
today.

A CLOSING THOUGHT

We are proud of what Wellington Fund, the other Vanguard Funds, and The
Vanguard Group have come to represent, and we are grateful for the success and
growth with which we have been blessed. We are an industry leader, and, as a
competitor observed a few years ago, we are "the standard by which all fund
organizations are judged."

         In battle terms, "the vanguard" is the first wave of troops or ships,
and Vanguard surely is in the first wave of the battle for investment survival.
As we look behind us, however, the "second wave" is not in sight. No fund
organization has followed our lead, leaving ours a lonely course. No matter. We
have an organization that places the interests of our Fund shareholders first.
We have Funds that shall endure the vicissitudes of the future. Come what may,
we intend to "stay the course," and we shall do our very best to continue to
deserve your confidence and loyalty. We hope that you will stay the course with
us.
