CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

The stock market has certainly put on a show since the start of the 
year. Stocks began 1997 on the high wires, bolstered by a near-perfect 
"Goldilocks" economy -- not too hot, not too cold. In almost a straight
shot, the Dow Jones Industrial Average soared through the 7000 level for 
the first time in early March. Just days later, stocks lost their 
footing and staged a month-long free-fall in a nervous reaction to 
rising interest rates and economic data that showed the economy was 
picking up steam. Stocks gave back all of their year's gain and suffered 
their worst decline since 1990 during this period. No sooner had real 
fears begun to beset investors then they were gone, erased in a euphoric 
rally caused by strong earnings and no signs of inflation. By the end of 
June, both the Dow and the broader Standard & Poor's 500 Stock Index had 
risen by 20% -- a level not many thought the market would reach all 
year, let alone in six months. Bondholders have not enjoyed the same 
bounty, as the bond market has mostly stayed worried about the strength 
of the economy, the direction of interest rates, and the Federal 
Reserve's next moves to pre-empt inflation. 

A 1 1/4" x 1" photo of Edward J. Boudreau Jr., Chairman and Chief 
Executive Officer, flush right, next to second paragraph.

But the stock market's latest advance has amazed many analysts and left 
them pondering their valuation models, since the market is now more 
expensive than it has been in decades. It's impossible to know what will 
happen next in the markets. But whether it's another strong move forward 
or a retreat, we recommend keeping a long-term perspective, rather than 
over-focusing on the market's daily twists and turns. While the economic 
backdrop seems to remain near perfect, the one thing we believe 
investors should be prepared for is more market volatility. It also 
makes sense to do something we've always advocated: set realistic 
expectations, since, as we've also seen this year, markets can move down 
as fast as they go up.

Use this time of heightened volatility as an opportunity to review your 
portfolio's asset allocations with your investment professional. After 
such a strong advance in equities over the last two and a half years, it 
could be time to rebalance your portfolio, if you haven't already, to 
maintain your desired targets of diversification. As part of that 
process, make sure that your investment strategies still reflect your 
individual time horizons, objectives and risk tolerance. 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 
Income Securities Trust

Careful sector allocation and credit selection 
help Fund performance in fitful environment

Fixed-income securities had a difficult time making headway during the 
first three months of the semiannual period. Investors nervously awaited 
each new economic report, hoping for some discernible signs as to the 
direction of the economy and the Federal Reserve Board's stance on 
monetary policy. Market turbulence was most pronounced in late February 
and March, prior to and in response to the Fed's pre-emptive strike 
against inflation, which entailed a .25% increase in the federal funds 
rate -- the rate that member banks charge each other for overnight 
loans. 

The second quarter registered improved performance, as a series of 
economic statistics indicating moderate growth and subdued inflation did 
much to calm investors' inflation concerns. The possibility that the Fed 
would raise short-term rates again in July became more remote with each 
new report, and set the stage for what could wind up being an uneventful 
summer. By the end of the six months ended June 30, 1997, the broad 
fixed-income market had rebounded enough to effectively offset the weak 
performance experienced months earlier.

A 2 1/4" x 3 1/2" photo of the Income Securities portfolio management 
team. Caption reads: "Jim Ho (seated) and Fund management team members 
(l - r) Lester Duke, Beverly Cleathero, Seth Robbins, Linda Carter". 

Against this fitful backdrop, John Hancock Income Securities Trust 
posted solid results, producing a total return of 3.91% at net asset 
value. The Fund outperformed the average open-end corporate debt A-rated 
fund, which produced a gain of 2.68% at net asset value, as tracked by 
Lipper Analytical Services, Inc.

"...the 
financial 
strength of 
corporate 
America 
helped boost 
corporate 
bond 
prices..."

Fund begins fiscal year on a defensive note 

Anticipating unsettled conditions upon entering fiscal 1997, we kept the 
Fund's average duration, a measure of the Fund's sensitivity to 
interest-rate changes, shorter than its competitors and its benchmark, 
the Lehman Brothers Government/Corporate Bond Index. We achieved this 
defensive orientation by aligning assets at opposite ends of the yield 
curve, owning both short-term and long-term securities to optimize total 
return potential. The yield curve flattened as bonds experienced 
downward pressure during the first quarter. This "barbell" strategy 
helped provide a level of stability. 

Chart with heading "Top Five Bond Sectors" at top left hand column. 
Chart lists five sectors: 1) Banks & Financials 28% 2) US Government & 
Agencies 27% 3) Utilities 14% 4) Media 5% 5)Transportation 5%. Footnote 
below states "As a percentage of net assets on June 30, 1997."

"Media, 
financial 
services 
and utility 
companies 
are three 
areas 
we have 
emphasized..."

As the period drew to a close, several leading indicators hinted at 
weaker-than-expected economic growth and the market began to pick up 
steam. Realizing the new data could well be enough to ease the Fed's 
inflation concerns, we became a bit less defensive and adjusted duration 
to a slightly more neutral position, redeploying assets in intermediate-
term securities and matching the benchmark's duration more closely. 
Believing the Fed will stand pat on interest rates throughout the 
summer, we anticipate maintaining this "ladder" positioning for the near 
term.

Table entitled "Scorecard" at bottom 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 "Owens Illinois" followed by an up arrow and the phrase "Tender offer 
sparks gains from sale of bonds". The second listing is "Riverwood

"Stabilization in paper prices". The third listing is "TCI Communications,
Inc." followed by an up arrow and the phrase "Benefited from consolidation 
trend". Footnote below reads: "See "Schedule of Investments." Investment 
holdings are subject to change."

Emerging markets add value

With the exception of a few weeks in late March and early April, yield 
spreads -- the difference in yields offered by corporate and Treasury 
bonds, and corporate bonds of varying credit quality -- continued to 
narrow, contributing to the Fund's solid performance. Investors' 
continuing appetite for yield and the financial strength of corporate 
America helped boost corporate bond prices and push yields lower, 
bringing them closer to one another and to the yields offered by 
Treasury securities. The Fund benefited substantially as corporate bonds 
comprised the bulk of the portfolio's net assets. 

As a natural result of narrowing yield spreads, risk premiums have come 
down. This means that the level of return one anticipates earning in 
exchange for taking on more risk is not as much as it was a year or two 
ago. The challenge for us then was to find securities with attractive 
yield potential commensurate with the risks involved in owning them. 
Given this reality, we have begun to upgrade the portfolio's credit 
quality by slightly reducing exposure to high-yield bonds. 

One way we have been able to improve quality without sacrificing yield 
has been to explore opportunities in emerging-market corporate bonds 
whose values are pegged to the U.S. dollar. As privatization and fiscal 
responsibility take hold in many emerging nations, attractive 
opportunities are coming to market. Our in-depth credit research has led 
us to several issues positioned to perform well, particularly bonds 
involved in project finance. Bonds issued by Transgas in Colombia to 
finance the construction of gas pipelines is a fine example. Other solid 
performers include Petros Mexicanos, a state-owned oil company in 
Mexico; Yanacocha, a Peruvian mining company; and Camuzzi Gas, a gas 
company in Argentina.

Bar chart with heading "Fund Performance" at top of left hand column. 
Under the heading is the footnote "For the six months ended June 30, 
1997." The chart is scaled in increments of 1% from top to bottom with 
0% at the bottom and 5% at the top. Within the chart, there are two 
solid bars. The first represents the 3.91% total return for John Hancock 
Income Securities Trust. The second represents the 2.68%  total return 
for the Average open-end corporate debt A-rated fund. Footnote below 
reads: "The total return for John Hancock Income Securities Trust is at 
net asset value with all distributions reinvested. The average open-end 
corporate debt A-rated fund is tracked by Lipper Analytical Services."

Issues such as these are compelling to own because no corporation's 
credit rating is allowed to be higher than that of its home country's 
government bonds. Consequently, the better creditworthiness of many 
emerging-market corporate debt securities is often masked.

Three industry sectors stand out 

The Fund's portfolio is broadly diversified with roughly 200 securities 
representing nearly 20 industry sectors. Media, financial services and 
utility companies are three areas we have emphasized over the period. 
The deregulation and consolidation that is taking place in the media 
sector has created numerous opportunities for debt issuers to receive 
credit upgrades. TCI Communications, Inc. is one holding that has 
performed extremely well.

Deregulation is also a theme in the utility industry. Many companies 
with below investment-grade ratings are being acquired by more 
financially sound firms. Long Island Lighting is in the process of being 
purchased by investment-grade rated Brooklyn Union Gas. The bonds issued 
by Long Island Lighting have enjoyed substantial price appreciation in 
anticipation of that event. 

Three types of financial securities have also helped the Fund: Yankee 
bonds, surplus notes and bank capital notes. Yankee bonds are dollar-
denominated high-quality foreign bank securities issued in the Unites 
States; surplus notes are highly-rated debt issued by insurance 
companies and bank capital notes are junior subordinated debt of a bank 
that is carried on balance sheets as equity, yet interest is deductible. 
These securities have not been widely followed by analysts, either 
because they are fairly new to the market or misunderstood. By 
conducting extensive research, we understood their potential early on 
and the Fund benefited when the market began to recognize it.

"...the Fed 
may raise 
interest rates 
before year's 
end."

Outlook: optimistic yet cautious

Market conditions appear more favorable now than when the fiscal year 
began. Although we are optimistic, we fully realize that with strong 
labor numbers and high consumer confidence, inflation worries will 
likely remain and the Fed may raise interest rates before year's end. 
Our plan is to keep the Fund's duration relatively similar to its 
benchmark for the near term and closely monitor upcoming economic 
reports for signals that would encourage us to shorten duration once 
again. Selectivity will continue to be emphasized in terms of credit 
quality and valuation. 

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.

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 gains and losses, distributions paid to 
shareholders, and any increase due to reinvestment of distributions in the Fund. The footnote illustrates the number of 
Fund shares outstanding at the beginning of the period, reinvested and outstanding at the end of the period, for the 
last two periods.

NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)
NOTE A --
ACCOUNTING POLICIES

John Hancock Income Securities Trust (the "Fund") is a closed-end 
investment management company registered under the Investment Company 
Act of 1940. 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.

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 transaction. 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 $52,353 of a capital loss 
carryforward available, to the extent provided by regulations, to offset 
future net realized capital gains. To the extent that such carryforward 
is used by the Fund, no capital gains distributions will be made. The 
carryforward expires on December 31, 2004.

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 dividends and distributions to shareholders from 
net investment income and realized gains on the ex-dividend date. Such 
distributions are determined in conformity with federal income tax 
regulations, which may differ from generally accepted accounting 
principles.

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.

DISCOUNT ON SECURITIES 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.

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 future 
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 June 30, 1997, open positions in financial futures contracts were as 
follows:

                                                            UNREALIZED

                                                             ======

At June 30, 1997, the Fund has deposited in a segregated account $5,000 
par value of U.S. Treasury Bond, 7.125% due 02-15-23, to cover margin 
requirements on open financial futures contracts.

NOTE B --
MANAGEMENT FEE AND
ADMINISTRATIVE SERVICES

Under the present investment management contract, the Fund pays a 
quarterly management fee to the Adviser, for a continuous investment 
program, equivalent on an annual basis, to the sum of (a) 0.650% 
of the first $150,000,000 of the Fund's average weekly net asset 
value, (b) 0.375% of the next $50,000,000, (c) 0.350% of the next 
$100,000,000 and (d) 0.300% of the Fund's average weekly net asset value 
in excess of $300,000,000.

In the event normal operating expenses of the Fund, exclusive of taxes, 
interest, brokerage commissions and extraordinary expenses, exceeds 1.5% 
of the first $30,000,000 of the Fund's average weekly net asset value 
and 1.0% of the Fund's average weekly net asset value in excess of 
$30,000,000, 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 Fund has an agreement with the Adviser to perform necessary tax and 
financial management services for the Fund. The compensation for the 
period was at an annual rate of 0.01875% of the average net assets of 
the 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 June 30, 1997, the Fund's investment 
to cover the deferred compensation had unrealized appreciation of 
$1,225.

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 period ended June 30, 1997 aggregated $55,625,058 and 
$62,237,213, respectively. Purchases and proceeds from sales of 
obligations of the U.S. government and its agencies aggregated 
$50,023,524 and $44,636,285, respectively.

The cost of investments owned at June 30, 1997 (excluding the corporate 
savings account) for federal income tax purposes was $162,947,023. Gross 
unrealized appreciation and depreciation of investments at June 30, 1997 
aggregated $3,553,090 and $2,464,454, respectively, resulting in net 
unrealized appreciation of $1,088,636.

DIVIDENDS AND DISTRIBUTIONS

During 1997, dividends from net investment income totaling $0.6025 per 
share was paid to shareholders. The dates of payment and the amounts per

       PAYMENT DATE                             DIVIDEND
      --------------                           ----------
      March 31, 1997                            $0.3025
      June 30, 1997                             $0.3000

INVESTMENT OBJECTIVE AND POLICY 

John Hancock Income Securities Trust is a closed-end diversified 
investment management company, shares of which were initially offered to 
the public on February 14, 1973 and are publicly traded on the New York 
Stock Exchange. Its investment objective is to generate a high level of 
current income consistent with prudent investment risk. The Fund invests 
in a diversified portfolio of freely marketable debt securities and may 
invest an amount not exceeding 20% of its assets in income-producing 
preferred and common stock. The Fund intends to engage in short-term 
trading, may issue a single class of senior securities not to exceed 33 
1/3% of its net assets at market value, may borrow from banks as a 
temporary measure for emergency purposes in amounts not to exceed 5% of 
the total assets at cost and may lend its portfolio securities. The Fund 
pays quarterly dividends from net investment income and intends to 
distribute any available net realized capital gains annually. All 
distributions are paid in cash unless the shareholder elects to 
participate in the Automatic Dividend Reinvestment Plan.

The Fund will invest primarily in debt securities that have at the time 
of purchase an investment-grade rating by Standard & Poor's Corporation 
(S&P) or Moody's Investors Service, Inc. (Moody's) or are unrated debt 
securities of comparable investment quality.  The Fund may invest up to 
25% of the value of its total assets in debt securities that at the time 
of purchase have a rating  below BBB by S&P or below Baa by Moody's 
which may be rated as low as CC/Ca (junk bonds) and unrated debt 
securities of comparable investment quality.  If any debt security is 
rated differently by Moody's and S&P, the security will be classified by 
the Adviser as belonging in the higher group.  The Fund is not obligated 
to dispose of securities whose securities are subsequently in default or 
that are down-graded below the above-stated ratings.

FINANCIAL FUTURES CONTRACTS

The Fund may buy and sell financial futures contracts and options on 
futures contracts to hedge against the effects of fluctuations in 
interest rates and other market conditions. The Fund's ability to hedge 
successfully will depend on the Adviser's ability to predict accurately 
the future direction of interest rate changes and other market factors. 
There is no assurance that a liquid market for futures and options will 
always exist. In addition, the Fund could be prevented from opening, or 
realizing the benefits of closing out, a futures or options position 
because of position limits or limits on daily price fluctuations imposed 
by an exchange.

The Fund will not engage in transactions in futures contracts and 
options on futures for speculation, but only for hedging or other 
permissible risk management purposes. All of the Fund's futures 
contracts and options on futures will be traded on a U.S. commodity 
exchange or board of trade. The Fund will not engage in a transaction in 
futures or options on futures if, immediately thereafter, the sum of 
initial margin deposits on existing positions and premiums paid for 
options on futures would exceed 5% of the Fund's total assets.

DIVIDEND REINVESTMENT PLAN

John Hancock Income Securities Trust offers shareholders the opportunity 
to elect to receive shares of the Fund's Common Shares in lieu of cash 
dividends. The Plan is available to all shareholders without charge. 
Any shareholder of record of John Hancock Income Securities Trust 
("Income Securities") may elect to participate in the Automatic Dividend 
Reinvestment Plan (the "Plan") and receive shares of Income Securities' 
Common Shares in lieu of all or a portion of the cash dividends.

Shareholders may join the Plan by filling out and mailing an 
authorization card showing an election to reinvest all or a portion of 
dividend payments. If received in proper form by State Street Bank and 
Trust Company, P.O. Box 8209, Boston, Massachusetts 02266-8209 (the 
"Agent Bank") not later than seven business days before the record date 
for a dividend, the election will be effective with respect to all 
dividends paid after such record date. Shareholders whose shares are 
held in the name of a broker or nominee should contact the broker, bank 
or nominee to participate in the Plan.

Participation in the Plan may be terminated at any time by written 
notice to the Agent Bank and such termination will be effective 
immediately. However, notice of termination must be received seven days 
prior to the record date of any distribution to be effective for that 
distribution. Upon termination, certificates will be issued representing 
the number of full shares of Common Shares held by the Agent Bank. A 
shareholder will receive a cash payment for any fractional share held.

The Agent Bank will act as agent for participating shareholders. The 
Board of Trustees of Income Securities will declare dividends from net 
investment income payable in cash or, in the case of shareholders 
participating in the Plan, partially or entirely in Income Securities' 
Common Shares. The number of shares to be issued for the benefit of each 
shareholder will be determined by dividing the amount of the cash 
dividend otherwise payable to such shareholder on shares included under 
the Plan by the per share net asset value of the Common Shares on the 
date for payment of the dividend, unless the net asset value per share 
on the payment date is less than 95% of the market price per share on 
that date, in which event the number of shares to be issued to a 
shareholder will be determined by dividing the amount of the cash 
dividend payable to such shareholder by 95% of the market price per 
share of the Common Shares on the payment date. The market price of the 
Common Shares on a particular date shall be the mean between the highest 
and lowest sales price on the New York Stock Exchange on that date. Net 
asset value will be determined in accordance with the established 
procedures of Income Securities. However, if as of such payment date the 
market price of the Common Shares is lower than such net asset value per 
share, the number of shares to be issued will be determined on the basis 
of such market price. Fractional shares, carried out to three decimal 
places, will be credited to your account. Such fractional shares will be 
entitled to future dividends.

The shares issued to participating shareholders, including fractional 
shares, will be held by the Agent Bank in the name of the participant. 
A confirmation will be sent to each shareholder promptly, normally 
within seven days, after the payment date of the dividend. The 
confirmation will show the total number of shares held by such 
shareholder before and after the dividend, the amount of the most recent 
cash dividend which the shareholder has elected to reinvest and the 
number of shares acquired with such dividend.

The reinvestment of dividends does not in any way relieve participating 
shareholders of any federal, state or local income tax which may be due 
with respect to such dividend. Dividends reinvested in shares will be 
treated on your federal income tax return as though you had received a 
dividend in cash in an amount equal to the fair market value of the 
shares received, as determined by the prices for shares of the Fund on 
the New York Stock Exchange as of the dividend payment date. 
Distributions from the Fund's long-term capital gains will be processed 
as noted above for those electing to reinvest in shares and will be 
taxable to you as long-term capital gains. The confirmation referred to 
above will contain all the information you will require for determining 
the cost basis of shares acquired and should be retained for that 
purpose. At year end, each account will be supplied with detailed 
information necessary to determine total tax liability for the calendar 
year.

Department, John Hancock Income Securities Trust, 101 Huntington Avenue, 
Boston, Massachusetts 02199-7603, 1-800-843-0090.
