CHAIRMAN'S MESSAGE

[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief
Executive Officer, flush right next to second paragraph.]

DEAR FELLOW SHAREHOLDERS:

The Year 2000 is fast approaching and people around the world are getting
ready to celebrate this historic transition to a new millennium. At John
Hancock Funds, we share the excitement, but we aren't popping the
champagne corks just yet. Rather, we are staying on the course that we set
more than two years ago to ensure that the transition to a new millennium
is a smooth one for our shareholders.

As many already know, the Year 2000 has created more than the prospect of
New Year's festivities of epic proportions. It has also presented the
world with a challenge: making sure that older computers, and any
equipment powered by computer chips, can properly read and process the
date "00" as 2000, not 1900. Much has been written about how the world
will weather the change. Some view it as a non-event, while others see the
potential for disruptions. How much disruption, and for how long, depends
on whom you talk to.

As a company, we recognize that the Year 2000 ("Y2K") phenomenon is an
important issue to be dealt with and we have made it a top priority. Two
years ago, John Hancock Funds put a full-time team of experts on the case
and established a company-wide program to evaluate all computer
applications and to modify or replace those that needed changing.

These modifications and replacements are nearly done, and the tests of all
our systems are on schedule for completion by the end of July. The rest of
1999 will be spent testing with our business partners and continuing to
participate in industry testing. We have also established additional
contingency plans beyond our regular ones to prepare for any challenges
that the Year 2000 might present. In the end, John Hancock will spend
approximately $90-$95 million to ensure we make a successful transition to
the Year 2000.

Throughout 1999, each of our quarterly "Fundamentals" newsletters is
featuring articles with more detailed information on Y2K matters of
importance to our shareholders. I encourage you to read them, or contact
one of our Customer Service Representatives at 1-800-225-5291 for another
copy. For your own peace of mind, we also recommend that you save your
1999 statements, especially those you receive between October and
December, so that you are able to check them against the first one you
receive in 2000. It's a measure of prudence, not panic. Good record
keeping is part of good planning.

No one knows how the dawning of the new millennium will unfold. Although
we cannot make any ironclad assurances, we are confident that the steps we
have taken will provide shareholders with as smooth a transition as
possible. Once that occurs, we will happily raise our glasses to toast the
New Year, future prosperity and our hopes to serve you well into the
2000's.

Sincerely,

/S/EDWARD J. BOUDREAU, JR.

John Hancock High Yield Bond Fund

Flight to safety hits high-yield bonds hard

During the last 12 months, high-yield bonds spiraled down to their lowest
level in almost a decade before rebounding in the second half of the
period. Last summer, growing financial turmoil in Asia, Russia and Latin
America sparked a massive flight to the safety of U.S. Treasury bonds and
caused nearly a complete dry-up of liquidity -- the ease of trading -- in
the bond market. Securities carrying the highest risk were the hardest
hit, including high-yield corporate and emerging-market bonds. Falling
commodity prices and fears of global economic meltdowns and lower
corporate profit growth worldwide also hurt energy and cyclical companies
such as paper, steel and air transport, whose fortunes are most closely
tied to changes in the economy.

By the end of 1998, however, investor sentiment improved dramatically
after the Federal Reserve Board and central banks worldwide responded to
the crisis by lowering interest rates. With liquidity returning to the
market and global economies appearing to stabilize, investors grew more
comfortable taking on higher levels of risk and turned away from
Treasuries in search of higher yield. High-yield bonds began a rally that
lasted until mid-April, when it stalled as an overwhelming supply of new
high-yield bonds was greeted with lackluster demand. Despite the
second-half surge, high-yield bonds did not gain back all their lost
ground and had difficulty posting positive returns for the year.

"...high-yield
bonds...

posting
positive
returns for
the year."

listing is Northwest Airlines 2.8%, the second is Key Energy Group 2.0%, the
third Nextel Communications 1.9%, the fourth Repap New Brunswick 1.5% and the
fifth P&L Coal Holdings 1.4%. A note below the table reads "As a percentage
of net assets on May 31, 1999."]

Performance review

For the year ended May 31, 1999, John Hancock High Yield Bond Fund's Class
A, Class B and Class C shares posted total returns of -9.85%, -10.54% and
- -10.54%, respectively, at net asset value. That compared to the -1.70%
return of the average high current yield fund, according to Lipper, Inc.1
Keep in mind that your net asset value return will be different from the
Fund's performance if you were not invested in the Fund for the entire
period and did not reinvest all distributions. Historical performance
information can be found on pages six and seven.

"we
maintained
our
value-based
buy-and-hold
strategy..."

The Fund's investments in emerging-market debt and industrial cyclical
companies had the greatest impact on the Fund's performance during the
year, as did our focus on lower-quality high-yield bonds rated B and CCC+.
During the first six months, these groups suffered the most. They also had
the biggest rebound in the second half of the year, although not enough to
close the performance gap with our peers. In our view, however, the recent
rally in these groups is a testament to why we stick to a consistent
investment strategy, rather than trying to follow the market's latest
vogues. As the turmoil grew, we pared some of our lower-quality
emerging-market issues and kept a higher level of cash. But otherwise we
maintained our value-based buy-and-hold strategy, holding on to our core
positions in the belief that they represented great values, at the same
time that they paid attractive yields.

[Table at bottom of left hand column entitled "Scorecard". The header for the
left column is "Investment" and the header for the right column is "Recent
Performance...and What's Behind the Numbers". The first listing is Gulf
States Steel followed by a down arrow with the phrase "Asian economic woes

Inc. followed by an up arrow with the phrase "Bonds tendered at attractive
price in company buyout." A note below the table reads "See 'Schedule of
Investments.' Investment holdings are subject to change."]

Cyclicals hurt by Asian slowdown

When Asian economies began to experience almost the equivalent of a
1930s-style depression last year, paper and steel companies felt the
impact. Since Asia has been the growth area for these industries, when
that region's economies ground to a halt, so did demand for both paper and
steel, causing product dumping and profit shortfalls. This hurt our
holdings in the stocks and bonds of steel companies Gulf States Steel and
Weirton Steel. We used the occasion to buy more of Weirton Steel when its
price was depressed because we believe the company's focus on tin-plate
product for food packaging makes it less susceptible to cyclical economic
forces. Asia's troubles also hurt Canadian paper companies Repap New
Brunswick and Abitibi-Consolidated (which also was hit by a strike). As we
have said before, we continue to like these paper companies in the long
term, since their assets are solid and mergers and acquisitions are a
dynamic trend in the industry. During the period, the latest example was
the formation by Abitibi and Norwegian paper company Norske Skog of a
strategic alliance to joint venture with Korean paper company Hansol to
form Pan-Asian Paper Company.

[Bar chart at top of left hand column with heading "Fund Performance". Under

first bar represents the -9.85% total return for John Hancock High Yield Bond
Fund Class A. The second bar represents the -10.54% total return for John
Hancock High Yield Bond Fund Class B. The third bar represents the -10.54%
total return for John Hancock High Yield Bond Fund Class C. The fourth bar
represents the -1.70% total return for Average high current yield fund. A
note below the chart reads "Total returns for John Hancock High Yield Bond
Fund are at net asset value with all distributions reinvested. The average
high current yield fund is tracked by Lipper, Inc.1 See the following two
pages for historical performance information."]

Energy bottoms; stock moves

Falling oil prices in 1998 also hurt our energy holdings, particularly Key
Energy Group. Believing that oil prices were bottoming, we began to
increase our stake in oil service companies when prices were extremely
depressed. We added to our positions in both Key Energy and Grey Wolf, a
domestic land-drilling company with solid assets that is predominately
involved in the growing area of natural gas production.

Our airline holdings also held back our performance, particularly
Northwest Airlines, which struggled with labor problems last year. Its
stock has rebounded in 1999, as Wall Street finally began to value the
company's strategic alliance with Continental Airlines, a move we were
early to recognize. We bought more Continental stock when it was extremely
cheap and it has risen by 30% since then.

The Fund's investment policies allow us to own a limited amount of stock,
which we do selectively depending on our company and industry analysis.
During this period, as the stock market rose to new highs, we sold some of
our stock positions that had hit our price targets, including Galileo
International, provider of a computer airlines reservation system, and
paper company Bowater.

"After their
downturn,
high-yield
bonds remain
attractively
valued..."

Cautious optimism; high-yield risk

Emerging from the difficult conditions high-yield bonds encountered last
year, we remain cautiously optimistic about their prospects. After their
downturn, high-yield bonds remain attractively valued, and that means
opportunities exist for discerning investors. That said, last year's
turmoil could still take its toll on some weaker high-yield companies,
with the potential for an increase in the number of high-yield companies
missing their earnings targets or defaulting on their loan payments.

We encourage investors to use this year as a reminder of the fact that the
higher level of income provided by high-yield bonds is generally
accompanied by a greater risk/reward profile than the higher-quality
portions of the bond market. By definition, companies rated below
investment grade are subject to a greater risk of default, and they are
also more volatile than other bonds. We will continue to consistently
apply solid fundamental analysis to find companies that are worth the
extra risk we take to own them, in our effort to provide the Fund with
strong current income and the potential for price gains.

This commentary reflects the views of the portfolio managers through the
end of the Fund's period discussed in this report. Of course, the
managers' views are subject to change as market and other conditions
warrant.

International investing involves special risks such as political, economic
and currency risks and differences in accounting standards and financial
reporting.

A LOOK AT PERFORMANCE

The tables on the right show the cumulative total returns and the average
annual total returns for the John Hancock High Yield Bond Fund. Total
return measures the change in value of an investment from the beginning to
the end of a period, assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable
sales charge of 4.5%. Prior to May 15, 1995, the maximum applicable sales
charge for Class A shares was 4.75%. Class B performance reflects a
maximum contingent deferred sales charge (maximum 5% and declining to 0%
over six years). Class C performance includes a contingent deferred sales
charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future
results. Keep in mind that the total return and share price of the Fund's
investments will fluctuate. As a result, your Fund's shares may be worth
more or less than their original cost, depending on when you sell them.
Please read your prospectus carefully before you invest or send money.

The Statement of Changes in Net Assets shows how the value of the Fund's
net assets has changed since the end of the previous period. The
difference reflects earnings less expenses, any investment and foreign
currency gains and losses, distributions paid to shareholders and any
increase or decrease in money shareholders invested in the Fund. The
footnote illustrates the number of Fund shares sold, reinvested and
repurchased during the last two periods, along with the corresponding
dollar value.

John Hancock Bond Trust (the "Trust") is an open-end management investment
company, registered under the Investment Company Act of 1940. The Trust
consists of three series: John Hancock High Yield Bond Fund (the "Fund"),
John Hancock Intermediate Government Fund and John Hancock Government
Income Fund (collectively, the "Funds"). Prior to April 1, 1999, the
Intermediate Government Fund was known as John Hancock Intermediate
Maturity Government Fund. The other two series of the Trust are reported
in separate financial statements. The investment objective of the Fund is
to maximize current income without assuming undue risk by investing in a
diversified portfolio consisting primarily of lower-rated, high-yielding
debt securities such as: domestic and foreign corporate bonds; debentures
and notes; convertible securities; preferred stocks; and domestic and
foreign government obligations. As a secondary objective, the Fund seeks
capital appreciation but only when it is consistent with the primary
objective of maximizing current income.

The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The shares of
each class represent an interest in the same portfolio of investments of
the Fund and have equal rights to voting, redemptions, dividends and
liquidation, except that certain expenses, subject to the approval of the
Trustees, may be applied differently to each class of shares in accordance
with current regulations of the Securities and Exchange Commission and the
Internal Revenue Service. Shareholders of a class which bears distribution
and service expenses under terms of a distribution plan have exclusive
voting rights to that distribution plan.

Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on
the basis of market quotations, valuations provided by independent pricing
services or at fair value as determined in good faith in accordance with
procedures approved by the Board of Trustees. Short-term debt investments
maturing within 60 days are valued at amortized cost, which approximates
market value. All portfolio transactions initially expressed in terms of
foreign currencies have been translated into U.S. dollars as described in
"Foreign Currency Translation" below.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock
Advisers, Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley
Financial Group, Inc., may participate in a joint repurchase agreement.
Aggregate cash balances are invested in one or more repurchase agreements,
whose underlying securities are obligations of the U.S. government and/or
its agencies. The Fund's custodian bank receives delivery of the
underlying securities for the joint account on the Fund's behalf. The
Adviser is responsible for ensuring that the agreement is fully
collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the
date of purchase, sale or maturity. Net realized gains and losses on sales
of investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment
company" by complying with the applicable provisions of the Internal
Revenue Code and will not be subject to federal income tax on taxable
income which is distributed to shareholders. Therefore, no federal income
tax provision is required. For federal income tax purposes, the Fund has
$21,790,325 of capital loss carryforwards available, to the extent
provided by regulations, to offset future net realized capital gains. To
the extent such carryforwards are used by the Fund, no capital gain
distributions will be made. The carryforwards expire May 31, 2007.
Additionally, net capital losses of $16,464,424 attributable to security
transactions incurred after October 31, 1998 are treated as arising on the
first day (June 1, 1999) of the Fund's next taxable year.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Dividend income on investment
securities is recorded on the ex-dividend date or, in the case of some
foreign securities, on the date thereafter when the Fund is made aware of
the dividend. Interest income on investment securities is recorded on the
accrual basis. Foreign income may be subject to foreign withholding taxes,
which are accrued as applicable.

The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ
from generally accepted accounting principles. Dividends paid by the Fund
with respect to each class of shares will be calculated in the same
manner, at the same time and will be in the same amount, except for the
effect of expenses that may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized
gains (losses) are calculated at the Fund level and allocated daily to
each class of shares based on the appropriate net assets of the respective
classes. Distribution and service fees, if any, are calculated daily at
the class level based on the appropriate net assets of each class and the
specific expense rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly
identifiable to an individual fund. Expenses which are not readily
identifiable to a specific fund are allocated in such a manner as deemed
equitable, taking into consideration, among other things, the nature and
type of expense and the relative sizes of the funds.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on
securities from either the date of issue or date of purchase over the life
of the security, as required by the Internal Revenue Code.

USE OF ESTIMATES The preparation of these financial statements in
accordance with generally accepted accounting principles incorporates
estimates made by management in determining the reported amounts of
assets, liabilities, revenues and expenses of the Fund. Actual results
could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for
temporary or emergency purposes, including the meeting of redemption
requests that otherwise might require the untimely disposition of
securities. Effective March 12, 1999, the Fund entered into a syndicated
line of credit agreement with various banks, and the agreements previously
in effect were terminated. This agreement enables the Fund to participate
with other funds managed by the Adviser in an unsecured line of credit
with banks which permit borrowings up to $500 million, collectively.
Interest is charged to each fund, based on its borrowing. In addition, a
commitment fee based on the average daily unused portion of the line of
credit is allocated among the participating funds. The Fund had no
borrowing activity for the year ended May 31, 1999.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates
and other market conditions. Buying futures tends to increase the Fund's
exposure to the underlying instrument. Selling futures tends to decrease
the Fund's exposure to the underlying instrument or hedge other Fund
instruments. At the time the Fund enters into a financial futures
contract, it will be required to deposit with its custodian a specified
amount of cash or U.S. government securities, known as "initial margin,"
equal to a certain percentage of the value of the financial futures
contracts being traded. Each day, the futures contract is valued at the
official settlement price of the board of trade or U.S. commodities
exchange on which it trades. Subsequent payments, known as "variation
margin," to and from the broker are made on a daily basis as the market
price of the financial futures contract fluctuates. Daily variation margin
adjustments, arising from this "mark to market," are recorded by the Fund
as unrealized gains or losses.

When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may
be an illiquid market and/or that a change in the value of the contract
may not correlate with changes in the value of the underlying securities.
In addition, the Fund could be prevented from opening or realizing the
benefits of closing out futures positions because of position limits or
limits on daily price fluctuations imposed by an exchange.

For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures
transactions.

At May 31, 1999, there were no open positions in financial futures
contracts.

FOREIGN CURRENCY TRANSLATION All assets and liabilities initially
expressed in terms of foreign currencies are translated into U.S. dollars
based on London currency exchange quotations as of 5:00 p.m., London time,
on the date of any determination of the net asset value of the Fund.
Transactions affecting statement of operations accounts and net realized
gain/(loss) on investments are translated at the rates prevailing at the
dates of the transactions.

The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held.
Such fluctuations are included with the net realized and unrealized gain
or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales of
foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on
the Fund's books and the U.S. dollar equivalent of the amounts actually
received or paid. Net unrealized foreign exchange gains or losses arise
from changes in the value of assets and liabilities other than investments
in securities at fiscal year end, resulting from changes in the exchange
rate.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS The Fund may enter into
forward foreign currency exchange contracts as a hedge against the effect
of fluctuations in currency exchange rates. A forward foreign currency
exchange contract involves an obligation to purchase or sell a specific
currency at a future date at a set price. The aggregate principal amounts
of the contracts are marked to market daily at the applicable foreign
currency exchange rates. Any resulting unrealized gains and losses are
included in the determination of the Fund's daily net assets. The Fund
records realized gains and losses at the time the forward foreign currency
contract is closed out or offset by a matching contract. Risks may arise
upon entering these contracts from potential inability of counterparties
to meet the terms of the contract and from unanticipated movements in the
value of a foreign currency relative to the U.S. dollar.

These contracts involve market or credit risk in excess of the unrealized
gain or loss reflected in the Fund's Statement of Assets and Liabilities.
The Fund may also purchase and sell forward contracts to facilitate the
settlement of foreign currency denominated portfolio transactions, under
which it intends to take delivery of the foreign currency. Such contracts
normally involve no market risk if they are offset by the currency amount
of the underlying transaction.

Open foreign currency forward sell contracts at May 31, 1999, were as
follows:

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program
equivalent, on an annual basis, to the sum of (a) 0.625% of the first
$75,000,000 of the Fund's average daily net asset value, (b) 0.5625% of
the next $75,000,000 and (c) 0.50% of the Fund's average daily net asset
value in excess of $150,000,000.

The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended May
31, 1999, net sales charges received with regard to sales of Class A
shares amounted to $3,550,647. Out of this amount, $310,007 was retained
and used for printing prospectuses, advertising, sales literature and
other purposes, $2,964,029 was paid as sales commissions to unrelated
broker-dealers and $276,611 was paid as sales commissions to sales
personnel of Signator Investors, Inc. ("Signator Investors"), a related
broker-dealer, formerly known as John Hancock Distributors, Inc. The
Adviser's indirect parent, John Hancock Mutual Life Insurance Company
("JHMLICo"), is the indirect sole shareholder of Signator Investors.

Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed.
Proceeds from the CDSC are paid to JH Funds and are used in whole or in
part to defray its expenses related to providing distribution related
services to the Fund in connection with the sale of Class B shares. For
the year ended May 31, 1999, contingent deferred sales charges paid to JH
Funds amounted to $2,197,985.

Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.0% of the lesser of the current market
value at the time of redemption or the original purchase cost of the
shares being redeemed. Proceeds from the CDSC are paid to JH Funds and are
used in whole or in part to defray its expenses related to providing
distribution related services to the Fund in connection with the sale of
Class C shares. For the year ended May 31, 1999, contingent deferred sales
charges paid to JH Funds amounted to $16,324.

In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distributions Plan
with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under
the Investment Company Act of 1940. Accordingly, the Fund will make
payments to JH Funds for distribution and service expenses, at an annual
rate not to exceed 0.25% of Class A average daily net assets and 1.00% of
Class B and Class C average daily net assets, to reimburse JH Funds for
its distribution and service costs. Up to a maximum of 0.25% of such
payments may be service fees as defined by the amended Rules of Fair
Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice, curtailment of a portion of the Fund's
12b-1 payments could occur under certain circumstances.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo.
The Fund pays transfer agent fees based on the number of shareholder
accounts and certain out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the year
was at an annual rate of less than 0.02% of the average net assets of the
Fund.

Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon
and Mr. Richard S. Scipione are trustees and/or officers of the Adviser
and/or its affiliates, as well as Trustees of the Fund. The compensation
of unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees
may elect to defer for tax purposes their receipt of this compensation
under the John Hancock Group of Funds Deferred Compensation Plan. The Fund
makes investments into other John Hancock funds, as applicable, to cover
its liability for the deferred compensation. Investments to cover the
Fund's deferred compensation liability are recorded on the Fund's books as
an other asset. The deferred compensation liability and the related other
asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investment as well as any unrealized
gains or losses. The investment had no impact on the operations of the
Fund.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales and maturities of securities, other than
obligations of the U.S. government and its agencies and short-term
securities, during the year ended May 31, 1999, aggregated $724,839,916
and $497,697,683, respectively. Purchases and proceeds from sales and
maturities of obligations of the U.S. government and its agencies during
the year ended May 31, 1999, aggregated $97,244,297 and $63,058,867,
respectively.

The cost of investments owned at May 31, 1999 for federal income tax
purposes was $1,274,295,675. Gross unrealized appreciation and
depreciation of investments aggregated $32,511,590 and $193,476,463,
respectively, resulting in net unrealized depreciation of $160,964,873.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended May 31, 1999, the Fund has reclassified amounts to
reflect an increase in accumulated net realized loss on investments of
$1,547,390, an increase in accumulated net investment income of $1,454,450
and an increase in capital paid-in of $92,940. This represents the amount
necessary to report these balances on a tax basis, excluding certain
temporary differences, as of May 31, 1999. Additional adjustments may be
needed in subsequent reporting periods. These reclassifications, which
have no impact on the net asset value of the Fund, are primarily
attributable to the treatment of foreign currency gains and losses, and
the Fund's use of the tax accounting practice known as equalization in the
computation of distributable income and capital gains under federal tax
rules versus generally accepted accounting principles. The calculation of
net investment income per share in the financial highlights excludes these
adjustments.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and

disclosures in the financial statements. Our procedures included
confirmation of securities owned as of May 31, 1999, by correspondence
with the custodian and brokers, or other appropriate auditing procedures
where replies from brokers were not received. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position
of the John Hancock High Yield Bond Fund of the John Hancock Bond Trust at
