CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

After two years of spectacular performance, the stock market in 1997 
has given investors its starkest reminder in a while of one of 
investing's basic tenets: markets move down as well as up. It's 
understandable if investors had lost sight of that fact. The bull 
market that began six years ago has given investors annual double-
digit returns and more modest price declines than usual. And in the 
two years encompassing 1995 and 1996, the S&P 500 Index gained more 
than 50%. This Pollyanna environment has tracked along with a 
sustained economic recovery, now in its seventh year, that has been 
marked by moderate growth, low interest rates and tame inflation. 

But recently, many have begun to wonder about this bull market. Since 
reaching new highs in early March, the Dow Jones Industrial Average 
tumbled by more than 7% at the end of March and wiped out nearly all 
it had gained since the start of the year. It was the worst decline 
that the market had seen since 1990. In early April, the Dow was down 
by 9.8%, within shouting distance of a 10% correction. By the end of 
the month, it had bounced back into record territory again.

As the market continues to fret over interest rates and inflation, 
investors should be prepared for more volatility. It also makes sense 
about 10%, not the 20%-plus annual average of the last two years or 
even the 16% annual average over the last 10 years. Remember that the 
kind of market volatility we've seen lately is more like the way the 
market really works. Fluctuations go with the territory. And market 
corrections can be healthy, serving to bring inflated stock prices 
down to more reasonable levels, thereby reducing some of the market's 
risk. 

Use this time of heightened volatility as an opportunity to review 
your portfolio's asset allocations with your investment professional. 
Make sure that your investment strategies reflect your individual time 
horizons, objectives and risk tolerance, and that they are based upon 
your needs. Despite turbulence, one thing remains constant. A well-
constructed plan and a cool head can be the best tools for reaching 
your financial goals.

Sincerely,

/S/ EDWARD J. BOUDREAU, JR.

John Hancock
Emerging Growth Fund

Small-company stocks remain out of favor, but
evidence suggests the tide may be turning

Small-company growth stocks, which are a primary focus for John 
Hancock Emerging Growth Fund, suffered a tough spell during the last 
six months when they fell out of investors' favor. The primary 
culprits for investors' lack of enthusiasm were uncertainties over the 
direction of economy and interest rates. While investors' seemingly 
insatiable appetite for large-company stocks sent the big-
capitalization Dow Jones Industrial Average to consecutive new 
records, their distaste for small-company stocks sent small company 
indexes into a tailspin. With the prospect for a slowing economy 
looming in light of rising interest rates, investors were less willing 
to pay the high prices that high-growth small-company stocks 
commanded. For the six-month period ended April 30, 1997, the Dow 
Jones Industrials rose 17.42% while the Russell 2000, a broad measure 
of small-company stock performance, posted a slight gain of 1.61%. 
Even the performance of the Russell 2000 Index doesn't accurately 
reflect the extent of small caps' decline. 

The past six months have served as a useful reminder that investing in 
aggressive-growth companies requires a healthy tolerance for a higher 
level of volatility and a long-term investment perspective. Although 
we recently weren't rewarded for sticking to our guns, we believe in 
staying with a disciplined investment strategy despite temporary 
periods of adversity. In our view, it's the best way to realize 
results over the long term.

Investors

migrate 
toward larger-
company 
stocks.

Performance review

For the six months ended April 30, 1997, the Fund's Class A and Class 
B shares had total returns of -6.39% and -6.73%, respectively, at net 
asset value. Those returns lagged that of the average small-company 
growth fund's average return of -3.50% for the same period, according 
to Lipper Analytical Services, Inc.1 Please see pages six and seven 
for longer-term performance information. Our relatively light 
weighting in financial stocks curtailed our performance in the wake of 
their strong showing during the period. And while we pared back our 
data networking company holdings and sidestepped their decline, we 
were hurt by our relatively heavy exposure to software companies, 
which experienced a sizable sell-off during the period. In addition to 
concerns about the economy's strength and rising interest rates, 
investors worried about an apparent slowdown of demand for networking 
products and services and the strengthening U.S. dollar. Many 
technology companies derive more than half of their sales from 
overseas markets. A strong dollar not only makes U.S. products more 
expensive to buy overseas, but also causes a decline in U.S. company 
profits when foreign currency purchases are converted back into 
dollars. 

Table entitled "Scorecard" at bottom of left hand column. The header for the 
left column is "Investments"; the header for the right column is "Recent 
performance ... and what's behind the numbers. The first listing is Dell 
Computer followed by an up arrow and the phrase "Captures bigger share of 
individual/corporate PC market." The second listing is Converse Technology 
followed by a down arrow and the phrase "Caught in technology sector 
downdraft." The third listing is 3-Com followed by a down arrow and the phrase 
"Suffered from increased competition in data networking market." Footnote 
below reads: "See "Schedule of Investments." Investment holdings are subject 
to change."

Comverse Technology, which produces special-purpose computer and 
telecommunication systems, was a stock we think was unfairly punished 
by the capricious stock market during the period. Shortly after the 
period ended, our patience was rewarded when Comverse rebounded to new 
highs. Even as some parts of the technology universe were hard hit, 
many of our semiconductor and hardware holdings including Teradyne, 
Tencor and Dell Computer enjoyed strong gains during the period. 

Looking ahead, our view is that while the hi-tech sector will likely 
remain volatile, we believe that many tech companies can continue to 
maintain their high levels of growth. But stock selection will be more 
important than ever. It's now clear that there has been some 
divergence within the technology universe, and only companies that can 
justify their stock prices with high rates of earnings growth will 
continue to do well. That's why we've pared back our technology 
holdings to roughly 25% of the Fund's assets, remaining selectively 
invested in software and semiconductor related companies that we 
believe continue to offer strong growth prospects. Baan Company, the 
dominant leader in company-wide planning of resources, is a good 
example of the type of tech stock we prefer. 

Winners: financial, real estate 

Although many stocks in the financial and real estate areas didn't fit 
our aggressive-growth criteria, some do, and they tended to post 
strong gains during the period. In the financial sector, one of our 
biggest winners was E* TRADE Group, which provides online discount-
broker services including order placement, portfolio tracking and 
related market information and news. The growing popularity of 
Internet trading sent E* TRADE's stock up more than 30% during the 
period. And many of our brokerage-related companies, including 
investment-banking/securities broker Alex Brown Inc., posted strong 
gains. General Re, which provides reinsurance and insurance in the 
United States and overseas, rose nearly 60%. In the real estate 
sector, Redwood Trust was one of our biggest winners. This company, 
which acquires and manages real-estate mortgage assets, rose 
handsomely since we bought it.



Bar chart with heading "Fund Performance" at top of left hand column. Under 
the heading is the footnote: "For the six months ended April 30, 1997." The 
chart is scaled in increments of 2% from top to bottom, with 0% at the top and 
- -8% at the bottom. Within the chart, there are three solid bars. The first 
represents the -6.39% total return for John Hancock Emerging Growth Fund: 
Class A. The second represents the -6.73% total return for John Hancock 
Emerging Growth Fund: Class B. The third represents the -3.50% total return 
for the average small-company growth fund. Footnote below reads: "Total 
returns for John Hancock Emerging Growth Fund are at net asset value with all 
distributions reinvested. The average small-company growth fund is tracked by 
Lipper Analytical Services, Inc.(1) See the following two pages for historical 
performance information." 

New opportunities 

We deployed the proceeds from the sale of some of our technology 
holdings into a diversified grouping of companies that fit our 
earnings and revenue growth criteria and that have dominant market 
share and superior, capable management teams. Recent additions 
include: Philip Environmental, which recycles wire and cable, fuels, 
paints, inorganic waste and other industrial by-products for resale to 
industry; Samsonite, a brand-name maker and distributor of luggage; 
and Quality Food Centers, a fast-growing Seattle-based supermarket 
chain. 

Outlook and strategy

In our view, many small-company growth stocks are now available at 
compelling prices given their prospects for fast growth and price 
appreciation. Late in the period we saw evidence that the situation 
could be taking a turn for the better, as small-stock prices moved 
north for the first time in several months. Although it may be 
premature to call it a rally, we believe that investors are finally 
beginning to recognize that after such a fall, small-company stocks 
are now down to price levels we haven't seen for years. We may be 
seeing the start of the change in the market's direction. We believe 
that it's not a question of if, but when, the market rewards these 
stocks. But until small-company stocks start moving back into 
investors' favor, they could continue to travel a bumpy road.

"... small-
company 
stocks are 
now down 
to price 
levels we 
haven't seen 
for years."

1Figures from Lipper Analytical Services, Inc. include reinvested 
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 Emerging Growth 
Fund. Total return is a performance measure that equals the sum of all 
dividends and capital gains, 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 5% 
for Class A shares. (Prior to May 15, 1995, the maximum applicable 
sales charge for Class A shares was 5.75%.) 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 the
John hancock Emerging Growth Fund would be worth on April 30, 1997,
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 standard & Poor's 500 Stock Index - an 
unmanaged index that includeds 500 widely traded common stocks and is 
a commonly used measure of stock market performance.

previous year. The difference reflects earnings less expenses, any investment gains and losses, and any increase or 
decrease in money shareholders invested in the Fund. The footnote illustrates the number of Fund shares sold and 
repurchased during the last two periods, along with the corresponding dollar value.

NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)
NOTE A --
ACCOUNTING POLICIES

John Hancock Series Trust (the "Trust") is a diversified, open-end 
management investment company, registered under the Investment Company 
Act of 1940. The Trust consists of two series portfolios: John Hancock 
Emerging Growth Fund (the "Fund") and John Hancock Global Technology 
Fund. The other series of the Trust is reported in separate financial 
statements. The investment objective of the Fund is to seek long-term 
growth of capital through investing in emerging companies (market 
capitalization of less than $1 billion). 

The Trustees 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 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 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, 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, net currency exchange gains and losses 
from sales of foreign debt securities may be treated as ordinary income 
even though such items are gains and losses for accounting purposes. 

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.

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. The Fund had no borrowing activity for the period ended 
April 30, 1997.

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.

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 0.75% of Fund's 
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 
April 30, 1997, net sales charges received with regard to sales of Class 
A shares amounted to $226,521. Out of this amount, $34,796 was retained 
and used for printing prospectuses, advertising, sales literature and 
other purposes, $153,846 was paid as sales commissions to unrelated 
broker-dealers and $37,879 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 ("JHMLICo"), is the 
indirect sole shareholder of Distributors and was the indirect sole 
shareholder until November 29, 1996 of 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 April 30, 1997, contingent-deferred 
sales charges paid to JH Funds amounted to $519,570.

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 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 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 and 
financial management services for the Funds. The compensation for the 
period was at an annual rate of 0.01875% of the average net assets of 
each Fund.

Mr. Edward J. Boudreau, Jr., 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. At April 30, 1997, the Fund's deferred 
compensation had an unrealized appreciation of $2,046.

CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

After two years of spectacular performance, the stock market in 1997 
has given investors its starkest reminder in a while of one of 
investing's basic tenets: markets move down as well as up. It's 
understandable if investors had lost sight of that fact. The bull 
market that began six years ago has given investors annual double-
digit returns and more modest price declines than usual. And in the 
two years encompassing 1995 and 1996, the S&P 500 Index gained more 
than 50%. This Pollyanna environment has tracked along with a 
sustained economic recovery, now in its seventh year, that has been 
marked by moderate growth, low interest rates and tame inflation. 

But recently, many have begun to wonder about this bull market. 
Since reaching new highs in early March, the Dow Jones Industrial 
Average tumbled by more than 7% at the end of March and wiped out 
nearly all it had gained since the start of the year. It was the 
worst decline that the market had seen since 1990. In early April, 
the Dow was down by 9.8%, within shouting distance of a 10% 
correction. By the end of the month, it had bounced back into record 
territory again.

As the market continues to fret over interest rates and inflation, 
investors should be prepared for more volatility. It also makes 
sense to do something we've always advocated: set realistic 
expectations. Keep in mind that the stock market's historic yearly 
average has been about 10%, not the 20%-plus annual average of the 
last two years or even the 16% annual average over the last 10 
years. Remember that the kind of market volatility we've seen lately 
is more like the way the market really works. Fluctuations go with 
the territory. And market corrections can be healthy, serving to 
bring inflated stock prices down to more reasonable levels, thereby 
reducing some of the market's risk. 

Use this time of heightened volatility as an opportunity to review 
your portfolio's asset allocations with your investment 
professional. Make sure that your investment strategies reflect your 
individual time horizons, objectives and risk tolerance, and that 
they are based upon your needs. Despite turbulence, one thing 
remains constant. A well-constructed plan and a cool head can be the 
best tools for reaching your financial goals.

Sincerely,

/S/ EDWARD J. BOUDREAU, JR.

John Hancock 
Global Technology Fund

Technology stocks post slight gains as investors 
worry about future growth

Technology stocks posted only modest gains over the past six months 
and once again lived up to their volatile reputation. Economic 
uncertainty and higher interest rates were the main culprits as 
investors worried about what effect these factors would have on 
technology companies' earnings. The strengthening U.S. dollar also 
acted as a drag, since many technology companies derive more than 
half of their sales from overseas markets. A strong dollar not only 
makes U.S. products more expensive for overseas buyers, but also 
causes a decline in U.S. company profits when foreign- denominated 
earnings are converted back into dollars.

The difficult six-month stretch was complicated by an about-face in 
investor preferences. Once the darlings of investors seeking hyper-
fast and accelerating earnings growth, tech stocks were shunned by 
investors who turned instead to companies offering more stable, 
predictable earnings growth. Despite changing perceptions, the 
reality was that technology companies remained among the fastest-
growing, and still continue to exceed most earnings estimates. But 
with economic and interest-rate uncertainty lingering over the stock 
market, investors began to balk at paying the high valuations tech 
stocks commanded. As a result, many technology stocks that once 
traded at high price to earnings multiples (a measure of how much 
you're paying for earnings), experienced a sharp decline from 
January through mid-April. The period ended with a rebound prompted 
by signs of continued strong tech company earnings, a strong economy 
and waning fears of higher interest rates.

1) Intel 5.1% 2) Computer Associates International 4.9% 
3) Microsoft 4.6%; 4) UAL Corp. 4.3% 5) United Technologies 3.6%.
A footnote below reads "As a percentage of net assets on

Performance review

For the six months ended April 30, 1997, the Fund's Class A and 
Class B shares posted total returns of 1.78% and 1.42%, 
respectively, at net asset value. That was slightly better than the  
1.19% return for the average science and technology fund, according 
to Lipper Analytical Services, Inc.1 Please see pages six and seven 
for longer-term performance information.

Our increasing focus on high-quality, larger-company stocks with 
brand name products and services worked well during this period. 
From personal computers for home use to sophisticated business 
systems for corporate use, the array and complexity of technology 
products has become quite overwhelming. It's no wonder that buyers -
- - be they consumers or corporate management information systems 
experts -- are confused. In our view, this confusion bodes well for 
brand-name technology providers that offer quality, one-stop-
shopping solutions and logical upgrade paths. That's why we 
continued to build the Fund's stake in companies such as software 
developer and marketer Microsoft, whose operating systems are now 
found in 90% of personal computers today. Its stock soared to about 
$121 at the end of the period, from roughly $68 six months earlier. 
Another large-company favorite was Intel, the leading maker of 
microprocessors, the silicon chips that are the brains of personal 
computers. Intel's stock rose more than 39% during the period. 

Over the last six months we increased our holdings in other 
companies involved with the manufacture and testing of semiconductor 
chips to about 20% of assets. That move was based on our view that 
the semiconductor sector was showing signs of improvement, which is 
in fact what occurred. Semiconductor-related holdings including 
Analog Devices, Applied Materials, KLA Instruments, LSI Logic, 
Micron Technology and VLSI Technology all posted sizable gains. 

We also profited from our holdings in aviation stocks AMR Corp., the 
parent company of American Airlines, and UAL, the parent of United 
Airlines. We had retained both from our merger with John Hancock 
National Aviation & Technology Fund. These stocks rebounded on the 
strength of the economy, lower costs and better profits. 

Our stake in networking stocks cost us during the period. Demand for 
networking products and services showed some signs of leveling off 
along with increased competition, and that prompted a sell-off in 
networking stocks. With questions about future demand still looming 
over networking companies, we sold some of our holdings in this 
area. One exception was Cisco Systems, the world's number one 
supplier of internetworking products that link local area and wide 
area networks (LANs and WANs).

total return for the average science and technology fund. A footnote 
below reads: "Total returns for John Hancock Global Technology Fund 
are at net asset value all distributions reinvested. The average 
science and technology fund is tracked by Lipper Analytical 
Services, Inc.(1) See following two pages for historical performance 
information."

Focus on software

Software remained a dominant focus throughout the period at about 
24% of assets. We believe it is becoming increasingly important as 
corporations need more information and control of their various 
hardware systems. In addition to Microsoft, we continued to favor 
companies such as Oracle, the world's largest maker of database 
management systems which let users create, retrieve and sort 
information in computer files. However, as Oracle hit our targeted 
value levels, it was essentially eliminated by the end of the 
period. While Oracle showed impressive gains during the period, 
other software companies proved less successful. Computer 
Associates, which designs software that allows users to manage their 
data processing more effectively, stumbled on marketing difficulties 
in Europe. We viewed those problems as temporary and saw the stock 
rebound sharply in April. The stocks of companies that make software 
to help engineers design products including industry leaders 
Parametric Technology, Synopsys and Cadance Design Systems also 
experienced difficulties. However, we are strong believers in this 
area of software with demand for products showing no signs of 
leveling off. 

Outlook

Our view is that technology companies' growth may continue to slow 
from an extraordinarily fast pace to a "merely" fast pace over the 
next six to 12 months. Nonetheless, we believe that the tech sector 
should continue to post growth rates much faster than the economy as 
a whole. What's more, the recent correction means that many fast-
growing tech company stocks can be had for cheaper prices than they 
were six months ago. That makes us optimistic about tech stocks' 
long-term prospects, although we do foresee continued volatility 
over the near term. As we've often said in the past, tech stocks may 
be too volatile for some investors with a short-term horizon. In our 
view, the best way to participate in their long-term growth 
prospects is to keep a long-term investment perspective. 

"...we do 
foresee 
continued 
volatility over 
the near 
term."

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 and 
currency risks and differences in accounting standards and financial 
reporting. Sector investing is subject to greater risks than the 
market as a whole.

A LOOK AT PERFORMANCE

The tables on the right show the cumulative total returns and the 
average annual total returns for the John Hancock Global Technology 
Fund. Total return is a performance measure that equals the sum of 
all income and capital gains distributions, assuming reinvestment of 
these distributions and the change in the price of the Fund's net 
asset value per share. Performance figures include the maximum 
applicable sales charge of 5% for Class A shares. 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. Performance is affected by a 12b-1 plan, which 
commenced on January 1, 1994 for both Class A and Class B shares. 
Different sales charge schedules for Class A shares were in effect 
prior to March 1987 and are not reflected in the performance 
information. 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.

     shares, respectively and the ratio of net investment income to average net assets would have been (1.01%) and 
     (1.74%) for Class A and Class B shares, respectively. As a result of such limitations, expenses of the Fund 
     for 1992 reflect reductions of $0.03 per share. Absent such limitations, for 1992, the ratio of expenses to 
     average net assets would have been 2.22% and the ratio of net investment income to average net assets would 
     have been (1.05%).

NOTES TO FINANCIAL STATEMENTS
 
(UNAUDITED)
NOTE A --
ACCOUNTING POLICIES

John Hancock Series Trust (the "Trust") is a diversified open-end 
management investment company, registered under the Investment 
Company Act of 1940. The Trust consists of two series: John Hancock 
Global Technology Fund (the "Fund") and John Hancock Emerging Growth 
Fund. The other series of the Trust is reported in separate financial 
statements. Until December 2, 1996 the Fund was a series of John 
Hancock Technology Series, Inc. The investment objective of the Fund 
is to achieve long-term capital growth by investing principally in 
equity securities of foreign and U.S. companies that rely extensively 
on technology in their product development or operations.

The Trustees 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 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 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, 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. 
Capital gains realized on some foreign securities are subject to 
foreign taxes and are accrued, as applicable.

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, net currency exchange gains and 
losses from sales of foreign debt securities must be treated as 
ordinary income even though such items are gains and losses for 
accounting purposes.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Dividend income on investment 
securities is recorded on the ex-dividend date. 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.

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 Company are directly 
identifiable to an individual fund. Expenses which are not 
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 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.

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. The Fund had no borrowing activity for the period ended 
April 30, 1997.

OPTIONS Listed options will be valued at the last quoted sales price 
on the exchange on which they are primarily traded. Purchased put or 
call over-the-counter options will be valued at the average of the 
"bid" prices obtained from two independent brokers. Written put or 
call over-the-counter options will be valued at the average of the 
"asked" prices obtained from two independent brokers. Upon the 
writing of a call or put option, an amount equal to the premium 
received by the Fund will be included in the Statement of Assets and 
Liabilities as an asset and corresponding liability. The amount of 
the liability will be subsequently marked to market to reflect the 
current market value of the written option.

The Fund may use option contracts to manage its exposure to the stock 
market. Writing puts and buying calls will tend to increase the 
Fund's exposure to the underlying instrument and buying puts and 
writing calls will tend to decrease the Fund's exposure to the 
underlying instrument, or hedge other Fund investments.

The maximum exposure to loss for any purchased options will be 
limited to the premium initially paid for the option. In all other 
cases, the face (or "notional") amount of each contract at value will 
reflect the maximum exposure of the Fund in these contracts, but the 
actual exposure will be limited to the change in value of the 
contract over the period the contract remains open.

Risks may also arise if counterparties do not perform under the 
contract's terms, or if the Fund is unable to offset a contract with 
a counterparty on a timely basis ("liquidity risk"). Exchange-traded 
options have minimal credit risk as the exchanges act as 
counterparties to each transaction, and only present liquidity risk 
in highly unusual market conditions. To minimize credit and liquidity 
risks in over-the-counter option contracts, the Fund will 
continuously monitor the creditworthiness of all its counterparties.

At any particular time, except for purchased options, market or 
credit risk may involve amounts in excess of those reflected in the 
Fund's period-end Statement of Assets and Liabilities.

Written option transactions for the period ended April 30, 1997 were 
as follows:

NOTE B --
MANAGEMENT FEE AND
TRANSACTIONS WITH AFFILIATES AND OTHERS

The Adviser is responsible for managing the Fund's investment 
business affairs and overseeing the investment activities of the sub-
adviser. The Adviser has a sub-investment management contract with 
American Fund Advisors, Inc. (the "Sub-Adviser"), under which the 
Sub-Adviser, subject to the review of the Directors and the overall 
supervision of the Adviser, provides the Fund with investment 
services and advice with respect to investment transactions. Under 
the present investment management contract, the Fund pays a monthly 
management fee to the Adviser, equivalent on an annual basis, to the 
sum of (a) 0.85% of the first $100,000,000 of the Fund's average 
daily net asset value and (b) 0.75% of the Fund's average daily net 
asset value in excess of $100,000,000. The Adviser pays the Sub-
Adviser a monthly management fee, equivalent on an annual basis, to 
the sum of (a) 0.35% of the first $100,000,000 of the Fund's average 
daily net asset value and (b) 40% of the investment advisory fee 
received by the Adviser on amounts over $100,000,000. The Fund pays a 
monthly administrative fee at the rate of $100,000 per annum to the 
Adviser for performance of administrative services to the Fund.

The Fund has a distribution agreement with John Hancock Funds, Inc. 
("JH Funds"), a wholly owned subsidiary of the Adviser. For the 
period ended April 30, 1997, net sales charges received with regard 
to sales of Class A shares amounted to $117,894. Out of this amount, 
$18,604 was retained and used for printing prospectuses, advertising, 
sales literature and other purposes, $68,362 was paid as sales 
commissions to unrelated broker-dealers and $30,928 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
("JHMLICo"), is the indirect sole shareholder of Distributors and was 
the indirect sole shareholder until November 29, 1996 of 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 April 30, 1997, 
contingent-deferred sales charges paid to JH Funds amounted to 
$133,242.

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 for distribution and service 
expenses, at an annual rate not to exceed 0.30% 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 Signature 
Services, Inc. ("Signature Services"), an indirect subsidiary of The 
Berkeley Financial Group. The Fund pays the transfer agent fee based 
on the number of shareholder accounts and certain out-of-pocket 
expenses.

Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon, and Mr. Richard S. 
Scipione are trustees and/or officers of the Adviser, and Mr. Barry 
J. Gordon is a director and officer of the Sub-Adviser. The 
compensation of unaffiliated Directors 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. At April 30, 1997, the Fund's investments 
to cover the deferred compensation liability had unrealized 
appreciation of $760.
