CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

Since late 1994, prospectus simplification has been a major topic 
in the mutual fund industry. At that time, Securities and Exchange 
Commission Chairman Arthur Levitt called on fund companies to
make their prospectuses more user-friendly. He noted that 
prospectuses are often overloaded with technical detail and are hard 
for most investors to understand. Many industry observers agreed, 
and rightly so.

So it is my pleasure to let you know that after being under 
development for a year, John Hancock Funds has introduced new 
simplified and consolidated prospectuses. The prospectuses feature 
shorter, clearer language with a streamlined design, and they 
incorporate several funds with similar investment objectives into 
one document. They cover our income, growth, growth and income, tax-
free income, international/global and money market funds. We are 
gratified at the favorable reviews that our new prospectuses have 
received from shareholders, financial advisers, industry analysts 
and the press. We believe they are a bold but sensible step forward. 
And while they are easier to read, they still comply with all 
federal and state guidelines.

We have taken the initiative to create a prospectus that 
dramatically departs from the norm. Among its most innovative 
features is a two-page spread highlighting each fund's goals and 
investment strategy, the types of securities it buys, its portfolio 
management and risk factors, all in plainer language. Fund expenses 
and financial highlights are now found here, too, as is a new bar 
chart that shows year-to-year volatility for each fund. Other 
features include a better presentation of fund services, a new 
glossary of investment risks and a discussion about how funds are 
organized, including a diagram showing the connection of the various 
players that provide services to your Hancock fund(s).

We believe we have made a significant advancement in the drive 
toward better mutual fund prospectuses. We hope you will agree 
because in the end, we did it for you, our shareholders.

Sincerely,

/S/EDWARD J. BOUDREAU, JR.

EDWARD J. BOUDREAU, JR., CHAIRMAN AND CHIEF EXECUTIVE OFFICER

John Hancock
High Yield Tax-Free Fund

Bonds stumble as economy gathers steam; 
high-yield securities not immune

Recently, the Fund's fiscal year end changed from October to August.  
What follows is a discussion of the Fund's performance for the 12 
months ended August 31, 1996.

The 12 months covered by this report span a volatile period in the 
bond market. Last November, bond prices were still climbing steadily 
as market participants anticipated the next rate cut by the Federal 
Reserve. Those expectations were fulfilled in mid-December when the 
Fed lowered the rate banks charge each other for overnight loans -- 
known as the federal funds rate -- one-quarter percentage point. 
Another quarter-point reduction -- the third since July 1995 -- 
followed in January 1996. At the time, many analysts confidently 
predicted that the Fed would go on cutting interest rates into the 
spring. Then came the February employment report, which showed jobs 
expanding at a rate about four times greater than expectations, and 
suddenly all bets were off. In the months that followed, evidence 
accumulated that the economy was indeed on the rebound, fueling 
speculation that the Fed would soon have to raise rates. The 
expected Fed action had yet to occur by the end of August, despite 
strong upward pressure on interest rates by market participants. The 
upshot, for high-yield bond investors, was a period in which 
interest payments compensated for declining bond prices, but just 
barely.

The bond 
market has
turned volatile 
in 1996.

Pie Chart entitled "Portfolio Diversification" at top left hand column. 
The chart is divided into 9 sections. Going from left to right: General 
Obligation 1%; Industrial Development Bonds 15%; Certificates of 
Participation 4%; Electric 3%; Health 9%; Housing 5%; Pollution Control 
27%; Transportation 15%; Other 20%; Water & Sewer 1%. A footnote below 
states "As a percentage of net assets on August 31, 1996".

"...we took 
steps to 
shorten the 
Fund's 
average 
duration."

John Hancock High Yield Tax-Free Fund produced total returns for the 
12 months ended August 31, 1996 of 3.25% and 2.52% for its Class A 
and Class B shares, respectively, at net asset value. That lagged 
the average high-yield municipal bond fund, which had a total return 
of 5.43% during the same period, according to Lipper Analytical 
Services. 1 Please see pages six and seven for longer-term 
performance information. Two factors prevented the Fund from keeping 
pace with its competitors: One, losses suffered on bonds issued by 
the Illinois Development Finance Authority for the Ford Heights 
Waste Tire Project, which went into bankruptcy this past spring; and 
two, falling prices for wood pulp, which undermined the Fund's 
holdings in several municipally financed de-inking facilities, 
including one in Marion County, West Virginia.

Table entitled "Scorecard" at bottom of left hand column. The header for 
the left column is "Investment"; the header for the right column is 
"Recent performance ... and what's behind the numbers. The first listing 
is San Jaoquin Transportation Corridor Agency followed by an up arrow 
and the phrase "Project nearing completion". The second listing is 
Cleveland Parking Facilities followed by an up arrow and the phrase 
"Bonds defeased with Treasuries". The third listing is Marion County 
followed by a down arrow and the phrase "Lower pulp prices". A footnote 
below states "See 'Schedule of Investments.' Investment holdings are 
subject to change".

Sector and strategy review

Even before the problems with the Ford Heights Incinerator project 
surfaced, the Fund was beginning to de-emphasize those kinds of 
project-specific municipal securities. Our preference lately has 
been for the broad class of securities known as industrial 
development bonds. These are tax-free securities issued by corporate 
borrowers for public purposes such as pollution control and economic 
development. Industrial development bonds, in which the underlying 
credit is backed by a private-sector corporation, tend to have 
stronger capital structures and more secure financing. During the 
period, industrial development bonds rose from about one-third of 
the Fund's net assets to about one-half. Top performers included 
bonds issued on behalf of several airlines, most notably 
Hillsborough County (Florida) Aviation Authority for USAir. The 
airlines have bounced back lately from their most recent earnings 
trough, thanks to improvements in cost control, employee relations 
and passenger yields.

Two other strategic choices we made during the period are worth 
noting. One, we broadened the Fund's individual holdings, aiming for 
a "basket approach." That meant diversifying among more issuers, 
more types of credits and more sectors. Second, as interest rates 
bottomed out during the first quarter of 1996, we took steps to 
shorten the Fund's average duration. Duration is an indicator of how 
much a bond's price will vary in response to changes in interest 
rates. At the end of 1995, the Fund's average duration was still 
fairly aggressive, about 8.5 years. Since then, we've adopted a more 
conservative stance by bringing the Fund's average duration back 
down to give us more flexibility in the face of rising rates. It 
stood at 7.6 years at the end of August.



Bar chart with heading "Fund Performance" at top of left hand column. 
Under the heading is the footnote: "For the year ended August 31, 1996." 
The chart is scaled in increments of 2%, with 6% at the top and 0% at 
the bottom. Within the chart there are three solid bars. The first 
represents the 3.25% total return for the John Hancock High Yield Tax-
Free Fund: Class A. The second represents the 2.52% total return for the 
John Hancock High Yield Tax-Free Fund: Class B. The third represents the 
5.43% total return for the average high-yield municipal bond fund. A 
footnote below states " Total returns for John Hancock High Yield Tax-
Free fund are at net asset value with all distributions reinvested. The 
average high-yield municipal bond fund is tracked by Lipper Analytical 
Services (1). See following two pages for historical performance 
information."

Other sectors in which the Fund had significant stakes included 
transportation, mainly toll roads such as one soon to be completed 
by the San Joaquin (California) Transportation Corridor Agency; 
utilities, the best example being Farmington County (New Mexico) for 
Public Service Company of New Mexico, which is experiencing strong 
earnings growth; and health care, a sector which has benefited 
recently from a wave of mergers and acquisitions.

Outlook

The Fund is emerging from a difficult period marked by losses 
suffered from our investment in the Ford Heights incinerator 
project. That credit was finally sold in June. During the final 
months of the current reporting period, the Fund performed more in 
line with other funds in its competitive universe, which bodes well 
for the future. We've taken steps to adapt to a changing 
environment. Strong credit analysis and diversification continue to 
underscore our portfolio strategy. And our continuing shift away 
from project financing in favor of tax-exempt corporate issues 
should improve the Fund's liquidity. Moreover, an expanding economy 
should work in our favor, as improving business conditions tend to 
strengthen credit quality. While there are concerns that too much 
growth could trigger inflation, as yet we've seen no evidence of 
this. That said, we maintain a cautious approach, mindful that the 
upcoming election and the possibility of Fed action may add an 
element of volatility to fixed-income markets. As we monitor the 
strength of the economy, we can make appropriate adjustments to the 
Fund's duration.

"...we 
maintain a
cautious a
approach..."

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

investing in high-yield bonds.

dividends and do not take into account sales charges. Actual load-
adjusted performance is lower. 



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 Tax-
Free Fund. Total return is a performance measure that equals the sum 
of all income and capital gain distributions, assuming reinvestment 
of these distributions and the change in the price of the Fund's 
shares, expressed as a percentage of the Fund's net asset value per 
share. Performance figures include the maximum applicable sales 
charge of 4.50% for Class A shares. (Prior to May 15, 1995, the 
maximum applicable sales charge for Class A shares was 4.75%.) The 
effect of the maximum contingent deferred sales charge for Class B 
shares (maximum 5% and declining to 0% over six years) is included 
in Class B performance. Remember that all figures represent past 
performance and are no guarantee of how the Fund will perform in the 
future. Also, 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.

WHAT HAPPENED TO A $10,000 INVESTMENT...

The charts on the right show how much a $10,000 investment in John 
Hancock High Yield Tax-Free Fund would be worth on August 31, 1996, 
assuming you had invested on the day each class of shares started 
and reinvested all distributions. For comparison, we've shown the 
same $10,000 investment in the Lehman Brothers Municipal Bond Index 
- -- an unmanaged index that includes approximately 15,000 bonds and 
is commonly used as a measure of municipal bond performance.

NOTES TO FINANCIAL STATEMENTS

John Hancock Funds - High Yield Tax-Free Fund

NOTE A --
ACCOUNTING POLICIES

John Hancock Series, Inc. (the "Corporation") is a diversified, 
open-end management investment company, registered under the 
Investment Company Act of 1940. As of August 31, the Corporation 
consists of four series portfolios: John Hancock High Yield Tax-Free 
Fund (the "Fund"), John Hancock Emerging Growth Fund, John Hancock 
Money Market Fund, and John Hancock Global Resources Fund 
(collectively, the "Funds"). The investment objective of the Fund is 
to obtain a high level of current income that is largely exempt from 
federal income taxes and is consistent with the preservation of 
capital.

The Board of Directors have authorized the issuance of multiple 
classes of shares of the Fund, designated as Class A and Class B 
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 Board of Directors, may be 
applied differently to each class of shares in accordance with 
current regulations of the Securities and Exchange Commission. 
Shareholders of a class which bears distribution/service expenses 
under terms of a distribution plan, have exclusive voting rights 
regarding such distribution plan. 

On June 25, 1996, the Board of Directors voted to change the fiscal 
period end from October 31 to August 31. This change is effective 
August 31, 1996.

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 
Directors. Short-term debt investments maturing within 60 days are 
valued at amortized cost which approximates market value.

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, 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's policy is to comply with the 
requirements of the Internal Revenue Code that are applicable to 
regulated investment companies and to distribute all of its taxable 
income, including any net realized gain on investment, to its 
shareholders. Therefore, no federal income tax provision is 
required. For federal income tax purposes, the Fund has $6,199,451 
of capital loss carryforwards available, to the extent provided by 
regulations, to offset future net realized capital gains. If such 
carryforward is used by the Fund, no capital gains distribution will 
be made. The carryforwards expire as follows: August 31, 2002 -- 
$2,785,979, August 31, 2003 -- $205,838, and, August 31, 2004 -- 
$3,207,634. Additionally, net capital losses of $3,207,634 
attributable to security transactions incurred after October 1, 1995 
are treated as arising on the first day (September 1, 1996) of the 
Fund's current taxable year. Effective August 31, 1996,  the Fund 
changed its tax year end from December 31 to August 31. 

DISTRIBUTIONS, DIVIDENDS AND INTEREST Interest income on investment 
securities is recorded on the accrual basis.

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 as explained previously.

EXPENSES  The majority of the expenses of the Corporation 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.



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/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.

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the 
amount paid in excess of par value on securities purchased from 
either the date of purchase or date of issue to date of sale, 
maturity or to next call date, if applicable. The Fund accretes 
original issue discount from par value on securities purchased from 
either the date of issue or the date of purchase over the life of 
the security, as required by the Internal Revenue Code. The Fund 
records market discount on bonds purchased after April 30, 1993 at 
time of disposition.

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 those estimates.

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. 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 contract being 
traded. Each day, the futures contract is valued at the official 
settlement price on the board of trade or U.S. commodities exchange. 
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", will be 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 contracts 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 fluctuation 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 contracts.

At August 31, 1996, open positions in financial futures contracts were 
as follows:

At August 31, 1996, the Fund has deposited in a segregated account 
$164,600 to cover margin requirements on open financial futures 
contracts.

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.

In the event normal operating expenses of the Fund, exclusive of 
certain expenses prescribed by state law, are in excess of the most 
restrictive state limit where the Fund is registered to sell shares, 
the fee payable to the Adviser will be reduced to the extent of such 
excess, and the Adviser will make additional arrangements necessary 
to eliminate any remaining excess expenses. The current limits are 
2.5% of the first $30,000,000 of the Fund's average daily net asset 
value, 2.0% of the next $70,000,000, and 1.5% of the remaining 
average daily net asset value.

The Fund has a distribution agreement with John Hancock Funds, Inc. 
("JH Funds"), a wholly owned subsidiary of the Adviser. For the 
period ended August 31, 1996, net sales charges received with regard 
to sales of Class A shares amounted to $217,313. Out of this amount, 
$21,579 was retained and used for printing prospectuses, 
advertising, sales literature and other purposes, $129,747 was paid 
as sales commissions to unrelated broker-dealers and $65,987 was 
paid as sales commissions to sales personnel of John Hancock 
Distributors, Inc. ("Distributors"), Tucker Anthony, Incorporated 
("Tucker Anthony") and Sutro & Co., Inc. ("Sutro"), all of which are 
broker dealers. The Adviser's indirect parent, John Hancock Mutual 
Life Insurance Company, is the indirect sole shareholder of 
Distributors and John Hancock Freedom Securities Corporation and its 
subsidiaries, which include Tucker Anthony and Sutro.  

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 period ended 
August 31, 1996, contingent deferred sales charges paid to JH Funds 
amounted to $289,505.

In addition, to reimburse JH Funds for the services it provides as 
distributor of shares of the Fund, the Fund has adopted a 
Distribution Plan with respect to Class A and Class B pursuant to 
Rule 12b-1 under the Investment Company Act of 1940. Accordingly, 
the Fund will make payments to JH Funds at an annual rate not to 
exceed 0.25% of Class A average daily net assets and 1.00% of Class 
B 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 Investor 
Services Corporation ("Investor Services"), a wholly-owned 
subsidiary of The Berkeley Financial Group. The Fund pays Investor 
Services a fee based on the number of shareholder accounts and 
certain out-of-pocket expenses.

On March 26, 1996, the Board of Directors approved retroactively to 
January 1, 1996, an agreement with the Adviser to perform necessary 
tax and financial management services for the Funds. The 
compensation for 1996 is estimated to be at an annual rate of 
0.01875% of the average net assets of each Fund.

Mr. Edward J. Boudreau Jr., Mr. Richard Scipione, and Ms. Anne C. 
Hodsdon are directors and/or officers of the Adviser and/or its 
affiliates, as well as Directors of the Fund. The compensation of 
unaffiliated Directors is borne by the Fund. Effective with the fees 
paid for 1995, the unaffiliated Directors 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. At August 31, 
1996, the Fund's investments to cover the deferred compensation 
liability had unrealized appreciation of $788.

The Fund has an independent advisory board composed of certain 
retired Directors who provide advice to the current Board of 
Directors in order to facilitate a smooth management transition. The 
Fund pays the advisory board and its counsel a fee. 

NOTE C --
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than 
obligations of the U.S. government and its agencies and short-term 
securities, during the fiscal period ended August 31, 1996, 
aggregated $65,049,957 and $60,894,694, respectively. There were no 
purchases or sales of obligations of the U.S. government and its 
agencies during the fiscal period ended August 31, 1996.

The cost of investments owned at August 31, 1996 for federal income 
tax purposes was $166,134,893. Gross unrealized appreciation and 
depreciation of investments aggregated $7,970,352 and $5,268,607 
respectively, resulting in net unrealized appreciation of 
$2,701,745.



NOTE D --
RECLASSIFICATION OF ACCOUNTS

During the year ended August 31, 1996, the Fund has reclassified 
amounts to reflect an increase in accumulated net realized loss on 
investments of $42,653, an increase in accumulated net investment 
income of $13,589 and an increase in capital paid-in of $29,064. 
This represents the amount necessary to report these balances on a 
tax basis, excluding certain temporary differences, as of August 31, 
1996. 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 certain 
differences 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.
