                                                               November 30, 1998









Dear Shareholders:

     Over  the  past  twelve months, U.S. Treasury securities have experienced a
strong  rally,  as  investors sought a safe haven from global market turmoil and
the  Federal  Reserve  continued  to  cut  interest rates. Other segments of the
fixed  income  market have lagged behind Treasuries, but still produced positive
returns  since  our  last  report.  We  anticipate that the Federal Reserve will
remain  prepared  to  combat  any signs of a credit crunch through interest rate
cuts,  and  given the unstable economic situation in Brazil, the Fed likely will
retain a loosening bias.

     Despite  previous  worries  of  a  second  half  slowdown in 1998, the U.S.
economy  continues  to  expand  rapidly.  Third  quarter  GDP  registered a 3.3%
annualized  growth  rate,  supported by strong consumer spending. This momentum,
however,  may  not  continue  as  briskly  into  the  new  year, based on weaker
corporate  profits  and  a  loosening  of  the  labor  markets.  Already,  major
corporations have warned of slower profit growth and announced major layoffs.

     This  report  contains  detailed  market  and  portfolio  strategy  by your
Trust's  managers  in addition to the Trust's audited financial statements and a
detailed  portfolio  list  of  the  portfolio's  holdings. We thank you for your
continued  investment  in  the Trust and look forward to serving your investment
needs in the future.



Sincerely,

                                                              November 30, 1998


Dear Shareholder:

     We  are pleased to present the annual report for The BlackRock Income Trust
Inc.  ("the Trust") for the fiscal year ended October 31, 1998. We would like to
take  this  opportunity  to  review  the Trust's stock price and net asset value
(NAV)  performance,  summarize  market developments and discuss recent portfolio
management activity.

     The  Trust  is  a  diversified, actively managed closed-end bond fund whose
shares  are  traded  on  the New York Stock Exchange under the symbol "BKT". The
Trust's  investment  objective is to provide high current income consistent with
the  preservation  of  capital.  The  Trust  seeks  this  objective by investing
primarily  in  mortgage-backed  securities  backed  by  U.S. Government agencies
(such  as  Fannie  Mae, Freddie Mac or Ginnie Mae) and, to a lesser extent, U.S.
Government   securities,   asset-backed   securities   and   privately   issued
mortgage-backed  securities.  At  least 85% of the Trust's assets must be issued
or  guaranteed by the U.S. government or its agencies or rated "AAA" by Standard
&  Poor's or "Aaa" Moody's (up to 5% can be unrated and deemed by the Adviser to
be  of  equivalent credit quality); the remaining 15% of the Trust's assets must
be  rated  at  least  "AA"  by  Standard  & Poor's or "Aa" by Moody's at time of
purchase.

     The  table  below summarizes the performance of the Trust's stock price and
NAV over the period:

THE FIXED INCOME MARKETS

     The  first  half  of  the  Trust's  fiscal  year  was  characterized by the
positive  momentum  and  bull  market trend that brought Treasury yields towards
historic  lows.  The  low Treasury yields were due to budget surplus projections
as  well  as  the  Fed's decision to move from a tightening to a neutral policy.
The  positive economic momentum throughout the first half of the fiscal year was
strengthened  by  unseasonably  warm  weather  that  led  to  increased consumer
spending  and job gains, and a less than expected impact on trade from the Asian
financial crisis.

     GDP  growth  measured  at  a  very strong 5% for the first quarter of 1998;
however,  signs  of  a  slowdown became evident when economic data for April and
May began to lag.

     The   second   half   of   the  trust's  fiscal  year  witnessed  virtually
unparalleled  market  turbulence.  During the second quarter of 1998, GDP growth
faltered  to  a  1.8%  rate due to slower output and an increasing trade deficit
created  by  a  strong  U.S. dollar. Although consumers continued their spending
domestically,  demand  for  U.S. goods abroad faltered, as the strong dollar and
weakness  overseas, especially Asia, drove prices for U.S. goods higher relative
to foreign goods.

     In  the  Trust's  final  quarter, U.S. GDP growth rebounded to a 3.3% pace;
however,  the  instability  in global financial markets began to rattle investor
confidence.  The  devaluation  of  the  Russian ruble and the fear of a possible
devaluation  of  the  Brazilian  currency  caused  a  flight-to-quality  to U.S.
Treasuries.  Spread sectors widened dramatically as a result of the sell-off. In
addition,  the  global  financial  markets  witnessed a credit crunch where even
higher-grade   securities   were  affected.  This  dramatic  shift  of  investor
sentiment culminated in the near collapse of a prominent hedge fund.

     The  Treasury  market rally pushed Treasury yields to historic levels below
the  5%  barrier.  In  response, to the financial fragility in the third quarter
1998  the  Fed  eased interest rates on September 29, 1998 by 25bps and again on
October  15,  in an unusual between-meetings move. On November 17, the Fed eased
interest rates again by 25bps.

THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

     BlackRock  actively  manages the Trust's portfolio holdings consistent with
BlackRock's  overall  market  outlook and the Trust's investment objectives. The
Trust  is  managed  to  maintain  an  interest  rate  sensitivity  (or duration)
approximately  150%  of the Salomon Brothers Mortgage Index; this means that the
portfolio's  NAV  will  change  roughly 1.5 times the price of the Index given a
change in interest rates.

     The  following  chart  compares  the  Trust's  current and October 31, 1997
asset composition:

</TABLE>

     Global  instability has caused a flight to quality to US Treasuries causing
mortgages  to severely underperform Treasuries as well as the broad bond market.
During  the period, mortgage-backed securities (MBS), as measured by the Salomon
Brothers  Mortgage  Index,  underperformed the broader investment grade domestic
bond  market  (Lehman  Aggregate  Index)  on  a  total return basis by 7.29% vs.
9.33%.

THE BLACKROCK INCOME TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. ORGANIZATION ACCOUNTING POLICIES

     The BlackRock Income Trust Inc. (the "Trust"), a Maryland & corporation, is
a  diversified   closed-end  management   in-vestment  company.  The  investment
objective  of the  Trust is to  achieve  high  monthly  income  consistent  with
preservation  of capital.  The ability of issuers of debt securities held by the
Trust to meet their  obligations  may be affected by economic  developments in a
specific  industry  or  region.  No  assurance  can be given  that  the  Trust's
investment objective will be achieved.

     The  following  is a summary of significant accounting policies followed by
the Trust.

SECURITIES  VALUATION: The  Trust values mortgage-backed, asset-backed and other
debt  securities,  interest  rate  swaps,  caps,  floors and non-exchange traded
options  on  the  basis  of  current  market  quotations  provided by dealers or
pricing  services approved by the Trust's Board of Directors. In determining the
value  of  a  particular  security, pricing services may use certain information
with  respect  to  transactions  in  such  securities,  quotations from dealers,
market  transactions in comparable securities, various relationships observed in
the  market between securities, and calculated yield measures based on valuation
technology  commonly employed in the market for such securities. Exchange-traded
options  are valued at their last sales price as of the close of options trading
on  the  applicable exchanges. In the absence of a last sale, options are valued
at  the  average of the quoted bid and asked prices as of the close of business.
A  futures  contract  is  valued  at  the last sale price as of the close of the
commodities  exchange  on  which it trades unless the Trust's Board of Directors
determines  that  such  price  does not reflect its fair value, in which case it
will  be  valued  at  its  fair  value  as  determined  by  the Trust's Board of
Directors.  Any  securities  or  other  assets  for  which  such  current market
quotations  are  not readily available are valued at fair value as determined in
good  faith  under  procedures  established by and under the general supervision
and responsibility of the Trust's Board of Directors.

     Short-term  securities  which  mature  in  60  days  or  less are valued at
amortized  cost,  if  their term to maturity from date of purchase is 60 days or
less.  Short-term  securities  with a term to maturity greater than 60 days from
the date of purchase are valued at current market quotations until maturity.

     In  connection  with  transactions  in  repurchase  agreements, the Trust's
custodian  takes  possession  of the underlying collateral securities, the value
of  which  at  least  equals the principal amount of the repurchase transaction,
including  accrued  interest.  To  the  extent  that  any repurchase transaction
exceeds  one  business day, the value of the collateral is marked-to-market on a
daily  basis  to  ensure  the adequacy of the collateral. If the seller defaults
and  the  value  of  the  collateral  declines  or if bankruptcy proceedings are
commenced  with  respect  to  the  seller  of  the  security, realization of the
collateral by the Trust may be delayed or limited.

OPTION  SELLING/PURCHASING: When  the  Trust  sells  or  purchases an option, an
amount  equal  to  the  premium  received  or paid by the Trust is recorded as a
liability  or  an asset and is subsequently adjusted to the current market value
of  the  option  written or purchased. Premiums received or paid from writing or
purchasing  options  which  expire  unexercised  are treated by the Trust on the
expiration  date as realized gains or losses. The difference between the premium
and  the  amount  paid  or  received  on  effecting  a  closing purchase or sale
transaction,  including  brokerage  commissions,  is  also treated as a realized
gain  or  loss. If an option is exercised, the premium paid or received is added
to  the  proceeds  from  the sale or cost of the purchase in determining whether
the  Trust  has realized a gain or a loss on investment transactions. The Trust,
as  writer  of  an  option,  may  have  no  control  over whether the underlying
securities  may  be  sold  (call)  or  purchased (put) and as a result bears the
market  risk  of  an  unfavorable change in the price of the security underlying
the written option.

     Options,  when  used by the Trust, help in maintaining a targeted duration.
Duration  is  a measure of the price sensitivity of a security or a portfolio to
relative  changes  in  interest  rates.  For instance, a duration of "one" means
that  a  portfolio's  or  a  security's  price  would  be  expected to change by
approximately  one  percent with a one percent change in interest rates, while a
duration  of  five  would  imply  that  the  price would move approximately five
percent in relation to a one percent change in interest rates.

     Option  selling  and purchasing is used by the Trust to effectively "hedge"
positions  so  that  changes in interest rates do not change the duration of the
portfolio  unexpectedly.  In  general, the Trust uses options to hedge a long or
short  position  or  an  overall  portfolio  that  is longer or shorter than the
benchmark  security.  A  call option gives the purchaser of the option the right
(but  not  obligation) to buy, and obligates the seller to sell (when the option
is  exercised),  the underlying position at the exercise price at any time or at
a  specified  time  during  the option period. A put option gives the holder the
right  to  sell  and  obligates the writer to buy the underlying position at the
exercise  price  at  any  time or at a specified time during the opti on period.
Put  options  can  be  purchased  to effectively hedge a position or a portfolio
against  price  declines if a portfolio is long. In the same sense, call options
can  be  purchased  to  hedge  a  portfolio  that  is shorter than its benchmark
against  price  changes. The Trust can also sell (or write) covered call options
and put options to hedge portfolio positions.


                                       13


<PAGE>

     The  main  risk  that  is  associated  with  purchasing options is that the
option  expires  without  being  exercised.  In  this  case,  the option expires
worthless  and  the premium paid for the option is considered the loss. The risk
associated  with  writing  call  options  is  that  the  Trust  may  forego  the
opportunity  for  a  profit  if  the  market  value  of  the underlying position
increases  and  the option is exercised. The risk in writing put options is that
the  Trust  may  incur  a  loss  if  the market value of the underlying position
decreases  and  the option is exercised. In addition, as with futures contracts,
the  Trust  risks  not  being  able  to enter into a closing transaction for the
written option as the result of an illiquid market.

INTEREST  RATE  SWAPS: In  a  simple  interest  rate  swap,  one investor pays a
floating  rate  of  interest on a notional principal amount and receives a fixed
rate  of  interest  on the same notional principal amount for a specified period
of  time. Alternatively, an investor may pay a fixed rate and receive a floating
rate.  Rate  swaps  were  conceived as asset/liability management tools. In more
complex  swaps,  the  notional  principal  amount may decline (or amortize) over
time.

     During  the  term  of  the  swap,  changes  in  the  value  of the swap are
recognized  as  unrealized gains or losses by "marking-to-market" to reflect the
market  value  of the swap. When the swap is terminated, the Trust will record a
realized  gain  or  loss  equal  to the difference between the proceeds from (or
cost  of) the closing transaction and the Trust's basis in the contract, if any.


     The  Trust is exposed to credit loss in the event of non-performance by the
other  party  to  the  mortgage  swap.  However,  the  Trust does not anticipate
non-performance by any counterparty.

SWAP  OPTIONS: Swap  options  are  similar  to options on securities except that
instead  of  selling  or  purchasing  the  right  to buy or sell a security, the
writer  or purchaser of the swap option is granting or buying the right to enter
into  a  previously  agreed upon interest rate swap agreement at any time before
the  expiration  of  the  option.  Premiums  received  or  paid  from writing or
purchasing  options  are  recorded as liabilities or assets and are subsequently
adjusted  to  the  current  market  value  of  the  option written or purchased.
Premiums  received  or  paid  from  writing  or purchasing options which expires
unexercised  are  treated  by the Trust on the expiration date as realized gains
or  losses.  The  difference between the premium and the amount paid or received
on  effecting  a  closing  purchase  or  sale  transaction,  including brokerage
commission,  is  also  treated  as  a  realized  gain  or  loss. If an option is
exercised,  the  premium paid or received is added to the proceeds from the sale
or  cost of the purchase in determining whether the Trust has realized a gain or
loss on investment transactions.

     The  main  risk that is associated with purchasing swap options is that the
swap  option  expires  without being exercised. In this case, the option expires
worthless  and  the premium paid for the swap option is considered the loss. The
main  risk  that  is  associated with the writing of a swap option is the market
risk  of an unfavorable change in the value of the interest rate swap underlying
the written swap option.

     Swap  options  may  be  used  by  the  Trust  to manage the duration of the
Trust's  portfolio  reflecting  the  view  of  the  Trust's  management  in  the
direction of interest rates.

FINANCIAL  FUTURES  CONTRACTS: A  futures  contract  is an agreement between two
parties  to  buy  and  sell  a  financial instrument for a set price on a future
date.  Initial margin deposits are made upon entering into futures contracts and
can  be  either  cash  or  securities. During the period the futures contract is
open,  changes  in  the value of the contract are recognized as unrealized gains
or  losses  by "marking- to-market" on a daily basis to reflect the market value
of  the  contract  at  the end of each day's trading. Variation margin pay ments
are  made  or  received,  depending  upon whether unrealized gains or losses are
incurred.  When  the  contract  is  closed, the Trust records a realized gain or
loss  equal to the difference between the proceeds from (or cost of) the closing
transaction and the Trust's basis in the contract.

     Financial  futures contracts, when used by the Trust, help in maintaining a
targeted  duration.  Futures  contracts  can  be  sold to effectively shorten an
otherwise  longer  duration  portfolio. In the same sense, futures contracts can
be  purchased  to lengthen a portfolio that is shorter than its duration target.
Thus,  by buying or selling futures contracts, the Trust can effectively "hedge"
positions  so  that  changes in interest rates do not change the duration of the
portfolio unexpectedly.

     The  Trust  may  invest  in  financial  futures contracts primarily for the
purpose  of  hedging  its  existing portfolio securities or securities the Trust
intends  to  purchase  against  fluctuations  in  value  caused  by  changes  in
prevailing  market  interest rates. Should interest rates move unexpectedly, the
Trust  may  not  achieve  the  anticipated  benefits  of  the  financial futures
contracts  and  may realize a loss. The use of futures transactions involves the
risk  of  imperfect  correlation in movements in the price of futures contracts,
interest  rates  and the underlying hedged assets. The Trust is also at the risk
of  not  being able to enter into a closing transaction for the futures contract
because  of an illiquid secondary market. In addition, since futures are used to
shorten  or  lengthen a portfolio's duration, there is a risk that the portfolio
may  have  temporarily  performed better without the hedge or that the Trust may
lose  the  opportunity  to  realize  appreciation  in  the  market  price of the
underlying positions.

SHORT  SALES: The  Trust  may  make  short  sales  of  securities as a method of
hedging  potential  price  declines  in similar securities owned. When the Trust
makes  a short sale, it may borrow the security sold short and deliver it to the
broker-dealer through


                                       14


<PAGE>

which  it  made  the  short sale as collateral for its obligation to deliver the
security  upon conclusion of the sale. The Trust may have to pay a fee to borrow
the  particular  securities  and  may  be  obligated  to  pay  over any payments
received  on such borrowed securities. A gain, limited to the price at which the
Trust  sold  the  security short, or a loss, unlimited as to dollar amount, will
be  recognized  upon  the  termination  of  a  short sale if the market price is
greater or less than the proceeds originally received.

SECURITIES  LENDING: The  Trust  may  lend its portfolio securities to qualified
institutions.  The loans are secured by collateral at least equal, at all times,
to  the  market  value  of the securities loaned. The Trust may bear the risk of
delay  in  recovery  of, or even loss of rights in, the securities loaned should
the   borrower   of   the   securities  fail  financially.  The  Trust  receives
compensation  for  lending  its  securities in the form of interest on the loan.
The  Trust  also continues to receive interest on the securities loaned, and any
gain  or loss in the market price of the securities loaned that may occur during
the term of the loan will be for the account of the Trust.

INTEREST  RATE  CAPS:   Interest  rate  caps are similar to interest rate swaps,
except  that  one  party  agrees  to  pay  a fee, while the other party pays the
excess, if any, of a floating rate over a specified fixed or floating rate.
     Interest  rate caps are intended to both manage the duration of the Trust's
portfolio  and its exposure to changes in short term rates. Owning interest rate
caps  reduces  the  portfolio's duration, making it less sensitive to changes in
interest  rates  from  a market value perspective. The effect on income involves
protection  from  rising short term rates, which the Trust experiences primarily
in the form of leverage.
     The  Trust is exposed to credit loss in the event of non-performance by the
other  party  to  the  interest rate cap. However, the Trust does not anticipate
non-performance by any counterparty.
     Transactions  fees  paid  or received by the Trust are recognized as assets
or  liabilities  and  amortized or accreted into interest expense or income over
the  life  of  the  interest  rate  cap.  The asset or liability is subsequently
adjusted  to  the  current  market  value  of the interest rate cap purchased or
sold.  Changes  in  the  value  of  the  interest  rate  cap  are  recognized as
unrealized gains and losses.

INTEREST  RATE  FLOORS: Interest rate floors are similar to interest rate swaps,
except  that  one  party  agrees  to  pay  a fee, while the other party pays the
excess, if any, of a floating rate under a specified fixed or floating rate.

     Interest  rate  floors are used by the Trust to both manage the duration of
the  portfolio and its exposure to changes in short-term interest rates. Selling
interest  rate floors reduces the portfolio's duration, making it less sensitive
to  changes  in  interest  rates  from  a  market value perspective. The Trust's
leverage  provides  extra  income  in  a period of falling rates. Selling floors
reduces  some  of  that  advantage  by  partially  monetizing  it as an up front
payment which the Trust receives.

     The  Trust is exposed to credit loss in the event of non-performance by the
other  party  to the interest rate floor. However, the Trust does not anticipate
non-performance by any counterparty.

     Transactions  fees  paid  or received by the Trust are recognized as assets
or  liabilities  and  amortized or accreted into interest expense or income over
the  life  of  the  interest  rate floor. The asset or liability is subsequently
adjusted  to  the  current  market value of the interest rate floor purchased or
sold.  Changes  in  the  value  of  the  interest  rate  floor are recognized as
unrealized gains and losses.

SECURITIES TRANSACTIONS AND NET INVESTMENT INCOME:
Securities  transactions are recorded on the trade date. Realized and unrealized
gains  and  losses  are calculated on the identified cost basis. Interest income
is  recorded  on the accrual basis and the Trust accretes discount and amortizes
premium  on  securities  purchased  using  the  interest  method.  Expenses  are
recorded  on the accrual basis which may require the use of certain estimates by
management.

TAXES: It  is  the Trust's intention to continue to meet the requirements of the
Internal  Revenue  Code  applicable  to  regulated  investment  companies and to
distribute  substantially  all of its taxable income to shareholders. Therefore,
no federal income tax provision is required.

DIVIDENDS   AND   DISTRIBUTIONS: The  Trust  declares  and  pays  dividends  and
distributions  monthly,  first  from  net  investment income, then from realized
short-term  capital gains and other sources, if necessary. Net long-term capital
gains,  if  any,  in  excess  of  loss  carryforwards  are  distributed at least
annually. Dividends and distributions are recorded on the ex-dividend date.

     Income  distributions  and  capital  gain  distributions  are determined in
accordance  with income tax regulations which may differ from generally accepted
accounting principles.

ESTIMATES: The  preparation of financial statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect  the  reported  amounts  of assets and liabilities and
disclosure  of  contingent  assets  and liabilities at the date of the financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting period. Actual results could differ from those estimates.

NOTE 2. AGREEMENTS

     The Trust has an Investment  Advisory  Agreement with  BlackRock  Financial
Management,  Inc.  (the  "Adviser"),  a wholly-  owned  corporate  subsidiary of
BlackRock Advisors, Inc., which is an indirect majority-owned  subsidiary of PNC
Bank,  N.A., and an  Administration  Agreement with Prudential  Investments Fund
Management LLC ("PIFM"), an indirect,  wholly-owned subsidiary of The Prudential
Insurance Co. of America.

     The  investment  fee  paid  to  the  Adviser is computed weekly and payable
monthly  at  an  annual  rate of 0.65% of the Trust's average weekly net assets.
The  administration fee paid to PIFM is also computed weekly and payable monthly
at  an  annual  rate  of  0.20% of the first $500 million of the Trust's average
weekly net assets and 0.15% of any excess.

     Pursuant  to the agreements, the Adviser provides continuous supervision of
the  investment  portfolio  and  pays the compensation of officers of the Trust.
PIFM  pays occupancy and certain clerical and accounting costs of the Trust. The
Trust bears all other costs and expenses.

NOTE 3. PORTFOLIO SECURITIES

     Purchases  and  sales  of  investment  securities,  other  than  short-term
investments  and dollar rolls,  for the year ended  October 31, 1998  aggregated
$1,589,447,018 and $1,509,958,130, respectively.

     The  Trust  may  invest  without  limit in securities which are not readily
marketable,  including  those  which  are  restricted  as  to  disposition under
securities  law  ("restricted  securities")  although  the Trust does not expect
that  such  investments  will  generally  exceed 25% of its portfolio assets. At
October  31,  1998,  the  Trust  held  3.8%  of its portfolio assets in illiquid
securities all of which were securities restricted as to resale.

     The  Trust  may  from time to time purchase in the secondary market certain
mortgage  pass-through  securities  packaged  or master serviced by PNC Mortgage
Securities  Corp.  (or Sears Mortgage if PNC Mortgage Securities Corp. succeeded
to  rights  and duties of Sears) or mortgage related securities containing loans
or  mortgages  originated  by PNC Bank or its affiliates, including Midland Loan
Services,  Inc.  It  is  possible  under  certain  circumstances,  PNC  Mortgage
Securities  Corp. or its affiliates, including Midland Loan Services, Inc. could
have  interests  that  are in conflict with the holders of these mortgage backed
securities,  and  such holders could have rights against PNC Mortgage Securities
Corp. or its affiliates, including Midland Loan Services, Inc.

     The  federal  income  tax  basis  of the Trust's investments at October 31,
1998   was  $682,726,382  and,  accordingly,  net  unrealized  appreciation  was
$10,246,379   (gross   unrealized  appreciation  $54,426,199;  gross  unrealized
depreciation $44,179,820).

     For  federal income tax purposes, the Trust has a capital loss carryforward
at  October  31,  1998  of  approximately  $69,599,900  of  which  approximately
$3,440,300  will  expire in 2001, approximately $23,358,100 will expire in 2002,
approximately  $15,428,300  will  expire  in  2003 and approximately $27,373,200
will  expire  in  2004.  Such carryforward is after utilization of approximately
$11,896,700  to  offset  the  Trust's  net  taxable gains recognized in the year
ended  October  31, 1998. Accordingly, no capital gains distribution is expected
to  be paid to shareholders until net gains have been realized in excess of such
amounts.

NOTE 4. BORROWINGS

REVERSE  REPURCHASE  AGREEMENTS:   The  Trust  enters  into  reverse  repurchase
agreements with qualified, third party broker-dealers as determined by and under
the  direction  of the  Trust's  Board of  Directors.  Interest  on the value of
reverse  repurchase  agreements issued and outstanding is based upon competitive
market  rates at the time of  issuance.  At the time  the  Trust  enters  into a
reverse repurchase agreement,  it establishes and maintains a segregated account
with the lender  containing liquid high grade securities having a value not less
than the repurchase price, including accrued interest, of the reverse repurchase
agreement.

     The  average  daily  balance  of  reverse repurchase agreements outstanding
during  the  year  ended  October  31,  1998 was approximately $218,735,000 at a
weighted  average  interest  rate  of approximately 5.47%. The maximum amount of
reverse  repurchase  agreements  outstanding  at any month-end during the period
was $198,335,893 as of October 31, 1998, which was 28.27% of total assets.

DOLLAR  ROLLS:  The  Trust  enters  into  dollar  rolls in which the Trust sells
securities  for  delivery  in  the current month and simultaneously contracts to
repurchase  substantially similar (same type, coupon and maturity) securities on
a  specified future date. During the roll period the Trust forgoes principal and
interest  paid  on  the  securities.  The  Trust  is compensated by the interest
earned  on  the  cash  proceeds  of the initial sale and by the lower repurchase
price  at  the future date. The Trust did not enter into dollar rolls during the
year ended October 31, 1998.



NOTE 5. CAPITAL

     There are 200 million shares of $.01 par value common stock authorized.  Of
the 62,849,878 shares  outstanding at October 31, 1998, the Adviser owned 10,753
shares.

NOTE 6. DIVIDENDS

     Since  October  31,  1998,  the Board of  Directors  of the Trust  declared
dividends from  undistributed  earnings of $0.046875 per share payable  November
16, 1998 to shareholders of record on November 30, 1998.

The Shareholders and Board of Directors of
The BlackRock Income Trust Inc.:

     We  have  audited  the  accompanying  statement  of assets and liabilities,
including  the  portfolio  of investments, of The BlackRock Income Trust Inc. as

     We  conducted  our  audits  in  accordance with generally accepted auditing
standards.Those  standards  require that we plan and perform the audit to obtain
reasonable  assurance  about  whether  the  financial  statements  and financial
highlights  are free of material misstatement. An audit includes examining, on a
test  basis,  evidence  supporting  the amounts and disclosures in the financial
statements.  Our procedures included confirmation of securities owned at October
31,  1998,  by  correspondence  with  the  custodian  and brokers. An audit also
includes  assessing  the  accounting  principles  used and significant estimates
made  by  management,  as  well  as  evaluating  the overall financial statement
presentation.  We  believe  that  our  audits provide a reasonable basis for our
opinion.



     In our opinion,  such financial statements and financial highlights present
fairly, in all material respects, the financial position of The BlackRock Income
Trust Inc. at October 31, 1998, and the results of its  operations,  the changes
in its net  investment  assets and its financial  highlights  for the respective

                        THE BLACKROCK INCOME TRUST INC.
                                TAX INFORMATION
- --------------------------------------------------------------------------------
     We  wish  to  advise  you  as  to  the  federal tax status of dividends and
distributions paid by the Trust during its fiscal year ended October 31, 1998

     During  the  fiscal  year  ended October 31, 1998, the Trust paid dividends
and  distributions  of  $0.56  per share from net investment income. For federal
income  tax  purposes,  the  aggregate  of  any dividends and short-term capital
gains  distributions you received are reportable in your 1998 federal income tax
return  as  ordinary  income.  Further,  we  wish to advise you that your income
dividends do not qualify for the dividends received deduction.

     We  are  required  by Massachusetts, Missouri and Oregon to inform you that
dividends  which  have been derived from interest on federal obligations are not
taxable  to  shareholders.  Please  be  advised that 9.66% of the dividends paid
from  ordinary  income  in  the  fiscal year ended October 31, 1998, qualify for
each of these states' tax exclusion.

     For  the  purpose  of preparing your 1998 annual federal income tax return,
however,  you  should  report  the  amounts as reflected on the appropriate Form
1099 DIV which will be mailed to you in January 1999.

- --------------------------------------------------------------------------------
                           DIVIDEND REINVESTMENT PLAN
- --------------------------------------------------------------------------------
     Pursuant   to   the   Trust's  Dividend  Reinvestment  Plan  (the  "Plan"),
shareholders  may elect to have all distributions of dividends and capital gains
automatically  reinvested  by  State  Street  Bank  &  Trust  Company (the "Plan
Agent")  in  Trust  shares  pursuant  to  the  Plan.  Shareholders  who  do  not
participate  in the Plan will receive all distributions in cash paid by check in
United  States  dollars mailed directly to the shareholders of record (or if the
shares  are  held  in  street or other nominee name, then to the nominee) by the
Custodian, as dividend disbursing agent.

     The  Plan  Agent  serves as agent for the shareholders in administering the
Plan.  After  the Trust declares a dividend or determines to make a capital gain
distribution,  the  Plan  Agent will, as agent for the participants, receive the
cash  payment and use it to buy Trust shares in the open market, on the New York
Stock  Exchange or elsewhere, for the participants' accounts. The Trust will not
issue shares under the Plan below net asset value.

     Participants  in the Plan may withdraw from the Plan upon written notice to
the  Plan  Agent and will receive certificates for whole Trust shares and a cash
payment will be made for any fraction of a Trust share.

     The  Plan  Agent's  fees  for the handling of the reinvestment of dividends
and  distributions will be paid by the Trust. However, each participant will pay
a  pro  rata  share  of  brokerage commissions incurred with respect to the Plan
Agent's  open  market purchases in connection with the reinvestment of dividends
and  distributions.  The  automatic  reinvestment of dividends and distributions
will  not  relieve participants of any federal, state or local income taxes that
may be payable on such dividend or distributions.

     Experience  under  the  Plan  may  indicate  that  changes  are  desirable.
Accordingly,  the  Trust  reserves  the  right to amend or terminate the Plan as
applied  to  any  dividend  or distribution paid subsequent to written notice of
the  change  sent  to  all shareholders of the Trust at least 90 days before the
record  date  for  the dividend or distribution. The Plan also may be amended or
terminated  by  the  Plan  Agent  upon  at  least 90 days' written notice to all
shareholders  of  the  Trust.  All  correspondence concerning the Plan should be
directed  to the Plan Agent at (800) 699-1BFM. The addresses are on the front of
this report.

                        THE BLACKROCK INCOME TRUST INC.
                             ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
     There  have  been  no material changes in the Trust's investment objectives
or  policies  that  have not been approved by the shareholders or to its charter
or  by-laws  or  in the principal risk factors associated with investment in the
Trust.  There  have been no changes in the persons who are primarily responsible
for the day-to-day management of the Trust's portfolio.


     YEAR  2000  READINESS  DISCLOSURE. The Trust is currently in the process of
evaluating  its  information technology infrastructure for Year 2000 compliance.
Substantially  all  of  the  Trust's  information  systems  are  supplied by the
Adviser.  The  Adviser  has  advised  the  Trust that it is currently evaluating
whether  such  systems  are  year  2000  compliant and that it expects to incure
costs  of  up  to  approximately  five hundred thousand dollars to complete such
evaluation  and  to make any modifications to its systems as may be necessary to
achieve  Year 2000 compliance. The Adviser has advised the Trust that it expects
to  have fully tested its systems for Year 2000 compliance by December 31, 1998.
The  Trust  may  be  required  to  bear  a  portion of such cost incurred by the
Adviser  in  this  regard.  The  Adviser  has advised the Trust that it does not
anticipate  any  material  disruption in the operations of the Trust as a result
of  any  failure by the Adviser to achieve Year 2000 compliance. There can be no
assurance  that  the  costs will not exceed the amount referred to above or that
the Trust will not experience a disruption in operations.


     The  Adviser  has advised the Trust that it is in the process of evaluating
the  Year 2000 compliance of various suppliers of the Adviser and the Trust. The
Adviser  has  advised  the  Trust  that  it  intends  to  communicate  with such
suppliers  to  determine  their  Year  2000  compliance status and the extent to
which  the  Adviser  or  the Trust could be affected by any supplier's Year 2000
compliance  issues.  To  date,  however,  the Adviser has not received responses
from  all  such  suppliers with respect to their Year 2000 compliance, and there
can  be  no  assurance  that  the  systems of such suppliers, who are beyond the
Trust's  control,  will  be  Year  2000  compliant. In the event that any of the
Trust's  significant  suppliers do not successfully and timely achieve Year 2000
compliance,  the Trust's business or operations could be adversely affected. The
Adviser  has  advised  the  Trust  that  it  is  in  the  process of preparing a
contingency  plan  for  Year  2000  compliance by its suppliers. There can be no
assurance  that  such  contingency  plan  will  be  successful  in  preventing a
disruption of the Trust's operations.


     The  Trust  is  designating  this  disclosure  as  its  year 2000 readiness
disclosure  for  all  purposes  under  the  Year  2000 Information and Readiness
Disclosure  Act  and  the  foregoing  information  shall  constitute a Year 2000
statement for purposes of that Act.

                        THE BLACKROCK INCOME TRUST INC.
                               INVESTMENT SUMMARY
- --------------------------------------------------------------------------------
THE TRUST'S INVESTMENT OBJECTIVE

The  BlackRock  Income  Trust's investment objective is to manage a portfolio of
high   grade   securities   to  achieve  high  monthly  income  consistent  with
preservation  of  capital.  The  Trust  will  seek  to  achieve its objective by
investing in Canadian and U.S. dollar-denominated securities.


WHO MANAGES THE TRUST?

BlackRock   Financial   Management,  Inc.  ("BlackRock")  is  an  SEC-registered
investment  adviser.  BlackRock  and  its  affiliates currently manage over $122
billion  on  behalf  of  taxable  and  tax-exempt  clients worldwide. Strategies
include  fixed  income,  equity  and  cash and may incorporate both domestic and
international   securities.   Domestic   fixed  income  strategies  utilize  the
government,  mortgage,  corporate  and municipal bond sectors. BlackRock manages
twenty-one  closed-end  funds that are traded on either the New York or American
stock  exchanges,  and  a  $23 billion family of open-end equity and bond funds.
Current  institutional  clients  number  410, domiciled in the United States and
overseas.


WHAT CAN THE TRUST INVEST IN?

The  Trust  will  invest  primarily  in  securities  issued or guaranteed by the
federal   governments   of   Canada  and  the  United  States,  their  political
subdivisions  (which  include  the  Canadian  provinces)  and their agencies and
instrumentalities.  The Trust's investments will be either government securities
or  securities  rated  "BBB"  or  higher at the time of investment by Standard &
Poor's  or "A2" by Moody's, or securities which BlackRock deems as of comparable
quality.  Under current market conditions, it is expected that the percentage of
the  Trust's  assets  invested in Canadian dollar-denominated securities will be
approximately  65%  and  75%. Examples of types of securities in which the Trust
may   invest   include   Canadian  and  U.S.  government  or  government  agency
residential   mortgage-backed   securities,   privately  issued  mortgage-backed
securities,  Canadian  provincial  debt  securities, U.S. Government securities,
commercial  mortgage-backed  securities,  asset-backed securities and other debt
securities  issued  by  Canadian and U.S. corporations and other entities. Under
current  market  conditions,  BlackRock  expects that the primary investments of
the  Trust  to  be Canadian mortgage-backed securities, Canadian provincial debt
securities,  U.S.  government  securities,  securities backed by U.S. government
agencies  (such  as  residential  mortgage-backed  securities), privately issued
mortgage-backed securities and commercial mortgage-backed securities.


WHAT IS THE ADVISER'S INVESTMENT STRATEGY?

The  Adviser  will seek to meet the Trust's investment objective by managing the
asset  of  the  Trust  so  as to provide high monthly income consistent with the
preservation  of  capital. The Trust will seek to provide monthly income that is
greater  than  that  which  could  be  obtained  by  investing  in U.S. Treasury
securities  with  an  average  life  similar  to  that of the Trust's assets. In
seeking  the investment objective, BlackRock actively manages the Trust's assets
in  relation  to market conditions and changes in general economic conditions in
Canada  and the U.S., including its expectations regarding interest rate changes
and  changes in currency exchange rates between the U.S. dollar and the Canadian
dollar,  to  attempt  to take advantage of favorable investment opportunities in
each  country. As such, the allocation between Canadian and U.S. securities will
change  from  time to time. Under current market conditions, the average life of
the  Trust's  assets is expected to be in the range of seven to ten years. Under
other  market  conditions,  the  Trust's  average  life  may vary and may not be
predictable using any formula.

While   the  Adviser  has  the  opportunity  to  hedge  against  currency  risks
associated  with  Canadian securities, the Trust is intended to provide exposure
to  the  Canadian  marketplace.  As a result, historically, currency hedging has
not  been  widely  practiced  by  the  Trust. However, BlackRock will attempt to
limit  interest  rate  risk  by  constantly  monitoring  the  duration (or price
sensitivity  with respect to changes in interest rates) of the Trust's assets so
that  it  is  within the range of U.S. Treasury securities with average lives of
seven  to  ten years. In doing so, the Adviser will attempt to locate securities
with   better   predictability   of   cash   flows   such   as  U.S.  commercial
mortgage-backed   securities.   In   addition,   the   Canadian  mortgage-backed
securities  in  which  the Trust invests are not prepayable, contributing to the
predictability of the Trust's cash flows. Traditional residential U.S.


                                       21


<PAGE>

mortgage  pass-through  securities  make  interest  and  principal payments on a
monthly  basis  and can be a source of attractive levels of income to the Trust.
While  the  U.S.  mortgage-backed  securities  in  the  Trust are of high credit
quality,  they  typically  offer  a  yield  spread  over  Treasuries  due to the
uncertainty  of the timing of their cash flows as they are subject to prepayment
exposure  when  interest  rates  change  and  mortgage  holders  refinance their
mortgages   or   move.  While  U.S.  mortgage-backed  securities  do  offer  the
opportunity  for  attractive  yields,  they subject a portfolio to interest rate
risk  and  prepayment  exposure  which  result in reinvestment risk when prepaid
principal must be reinvested.


HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD?

Does  the  Trust  Pay  Dividends Regularly? The Trust's shares are traded on the
New  York  Stock  Exchange  which  provides  investors with liquidity on a daily
basis.  Orders  to  buy  or  sell  shares  of the Trust must be placed through a
registered  broker  or financial advisor. The Trust pays monthly dividends which
are  typically  paid  on  the last business day of the month. For shares held in
the  shareholder's name, dividends may be reinvested in additional shares of the
Trust  through  the  Trust's  transfer agent, State Street Bank & Trust Company.
Investors  who  wish  to  hold  shares  in a brokerage account should check with
their  financial  advisor  to  determine  whether  their  brokerage  firm offers
dividend reinvestment services.


LEVERAGE CONSIDERATIONS IN THE TRUST

Under  current  market  conditions,  leverage increases the income earned by the
Trust.  The  Trust  employs  leverage  primarily  through  the  use  of  reverse
repurchase  agreements  and  dollar  rolls. Leverage permits the Trust to borrow
money  at  short-term  rates and reinvest that money in longer-term assets which
typically  offer  higher  interest rates. The difference between the cost of the
borrowed  funds  and  the  income  earned  on  the proceeds that are invested in
longer  term  assets  is the benefit to the Trust from leverage. In general, the
portfolio is typically leveraged at approximately 331|M/3% of total assets.

Leverage  also increases the duration (or price volatility of the net assets) of
the  Trust,  which  can improve the performance of the Trust in a declining rate
environment,  but  can  cause  net assets to decline faster than the market in a
rapidly  rising  rate  environment.  BlackRock's portfolio managers continuously
monitor  and  regularly  review  the  Trust's  use of leverage and the Trust may
reduce,  or  unwind,  the  amount of leverage employed should BlackRock consider
that reduction to be in the best interest of shareholders.


SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST

THE  TRUST  IS  INTENDED  TO  BE  A LONG-TERM INVESTMENT AND IS NOT A SHORT-TERM
TRADING VEHICLE.

INVESTMENT  OBJECTIVE. Although  the  objective  of the Trust is to provide high
monthly  income  consistent  with  preservation  of  capital,  there  can  be no
assurance that this objective will be achieved.

DIVIDEND  CONSIDERATIONS. The  income and dividends paid by the Trust are likely
to  vary  over  time  as fixed income market conditions change. Future dividends
may be higher or lower than the dividend the Trust is currently paying.

CURRENCY  EXCHANGE  RATE  CONSIDERATIONS. Because the Trust's net asset value is
expressed  in  U.S.  dollars,  and the Trust invests a substantial percentage of
its  assets  in  Canadian  dollar-denominated assets, any change in the exchange
rate  between these two currencies will have an effect on the net asset value of
the  Trust.  As  a  result,  if the U.S. dollar appreciates against the Canadian
dollar,  the  Trust's  net  asset  value  would  decrease if not offset by other
gains.

LEVERAGE. The  Trust utilizes leverage through reverse repurchase agreements and
dollar  rolls,  which  involves  special  risks. The Trust's net asset value and
market value may be more volatile due to its use of leverage.

MARKET  PRICE  OF  SHARES. The shares of closed-end investment companies such as
the  Trust  trade  on the New York Stock Exchange (NYSE symbol: BNA) and as such
are  subject to supply and demand influences. As a result, shares may trade at a
discount or a premium to their net asset value.


                                       22


<PAGE>

MORTGAGE-BACKED   AND   ASSET-BACKED   SECURITIES. The   cash   flow  and  yield
characteristics  of  these  securities  differ from traditional debt securities.
The   major  differences  typically  include  more  frequent  payments  and  the
possibility  of  prepayments  on  certain  U.S. mortgage-backed securities which
will change the yield to maturity of the security.

ILLIQUID  SECURITIES. The  Trust  may  invest  in  securities that are illiquid,
although  under  current  market conditions the Trust expects to do so to only a
limited extent. These securities involve special risks.

NON-U.S.  SECURITIES. The  Trust  may invest a portion of its assets in non-U.S.
dollar-denominated  securities  which  involve  special  risks such as currency,
political  and economic risks, although under current market conditions does not
do so.

ANTITAKEOVER  PROVISIONS. Certain  antitakeover provisions will make a change in
the  Trust's  business  or management more difficult without the approval of the
Trust's  Board of Directors and may have the effect of depriving shareholders of
an  opportunity  to  sell  their shares at a premium above the prevailing market
price.

GOVERNMENT SECURITIES:             Securities  issued or  guaranteed by the U.S.
                                   government,   or  one  of  its   agencies  or
                                   instrumentalities,  such as GNMA  (Government
                                   National Mortgage Association), FNMA (Federal
                                   National  Mortgage   Association)  and  FHLMC
                                   (Federal Home Loan Mortgage Corporation).

INTEREST-ONLY SECURITIES (I/O):    Mortgage  securities  that  receive  only the
                                   interest cash flows from an  underlying  pool
                                   of mortgage loans or underlying  pass-through
                                   securities. Also known as a STRIP.

INVERSE-FLOATING RATE MORTGAGES:   Mortgage instruments with coupons that adjust
                                   at periodic intervals  according to a formula
                                   which  sets  inversely  with a  market  level
                                   interest rate index.

MARKET PRICE:                      Price per share of a security  trading in the
                                   secondary market. For a closed-end fund, this
                                   is the  price at which  one share of the fund
                                   trades on the stock exchange.  If you were to
                                   buy or sell shares,  you would pay or receive
                                   the market price.

MORTGAGE DOLLAR ROLLS:             A mortgage  dollar roll is a  transaction  in
                                   which  the  Trust  sells   mortgage-   backed
                                   securities  for delivery in the current month
                                   and  simultaneously  contracts to  repurchase
                                   substantially similar (although not the same)
                                   securities on a specified future date. During
                                   the "roll" period, the Trust does not receive
                                   principal   and  interest   payments  on  the
                                   securities,  but is compensated for giving up
                                   these  payments  by  the  difference  in  the
                                   current  sales price (for which the  security
                                   is sold) and lower  price that the Trust pays
                                   for the  similar  security at the end date as
                                   well  as the  interest  earned  on  the  cash
                                   proceeds of the initial sale.

MORTGAGE PASS-THROUGHS:            Mortgage-backed  securities  issued by Fannie
                                   Mae, Freddie Mac or Ginnie Mae.

MULTIPLE-CLASS PASS-THROUGHS:      Collateralized   Mortgage  Obligations.   Net

                                   accrued   on  its   investments,   minus  any
                                   liabilities   including   accrued   expenses,
                                   divided  by the total  number of  outstanding
                                   shares.  It  is  the  underlying  value  of a
                                   single  share on a given day. Net asset value
                                   for  the  Trust  is  calculated   weekly  and
                                   published  in BARRON'S  on  Saturday  and THE
                                   WALL STREET JOURNAL each Monday.

PRINCIPAL-ONLY SECURITIES (P/O):   Mortgage  securities  that  receive  only the
                                   principal cash flows from an underlying  pool
                                   of mortgage loans or underlying  pass-through

PREMIUM:                           When a fund's stock price is greater than its
                                   net  asset  value,  the  fund  is  said to be
                                   trading at a premium.

RESIDUALS:                         Securities    issued   in   connection   with
                                   collateralized   mortgage   obligations  that
                                   generally represent the excess cash flow from
                                   the mortgage assets  underlying the CMO after
                                   payment  of  principal  and  interest  on the
                                   other    CMO     securities    and    related
                                   administrative expenses.

REVERSE REPURCHASE AGREEMENTS:     In a reverse repurchase agreement,  the Trust
                                   sells  securities  and  agrees to  repurchase
                                   them at a  mutually  agreed  date and  price.
                                   During  this  time,  the Trust  continues  to
                                   receive the principal  and interest  payments
                                   from that  security.  At the end of the term,
                                   the Trust receives the same  securities  that
                                   were sold for the same initial  dollar amount
                                   plus  interest  on the cash  proceeds  of the
                                   initial sale.

STRIPPED MORTGAGE BACKED           Arrangements  in  which a pool of  assets  is

                                   different  proportions  of the  interest  and
                                   principal    distribution   from   underlying
                                   mortgage-backed securities. IO's and PO's are
                                   examples of STRIPs.

senior/subordinated pass-through and the multi-class asset-backed security.

     BlackRock  is  unique  among  asset  management  and  advisory firms in the
emphasis  it  places  on the development of proprietary analytical capabilities.
Over  one  quarter  of  the  firm's  professionals  is  dedicated to the design,
maintenance  and  use  of  these  systems,  which are not otherwise available to
investors.  BlackRock's  proprietary  analytical  tools are used for evaluating,
and   designing  fixed  income  investment  strategies  for  client  portfolios.
Securities  purchased  include mortgages, corporate bonds, municipal bonds and a
variety of hedging instruments.

     BlackRock  has  developed  investment  products  that respond to investors'
needs  and  has  been  responsible  for  several major innovations in closed-end
funds.  In  fact,  BlackRock  introduced the first closed-end mortgage fund, the
first  taxable and tax-exempt closed-end funds to offer a finite term, the first
closed-end  fund  to  achieve  a  AAA rating by Standard & Poor's, and the first
closed-end  fund  to  invest  primarily in North American Government securities.
Currently,  BlackRock's closed-end funds have dividend reinvestment plans, which
are  designed  to  provide ongoing demand for the stock in the secondary market.
BlackRock  manages  a  wide  range  of investment vehicles, each having specific
investment objectives and policies.

     In  view  of our continued desire to provide a high level of service to all
our  shareholders,  BlackRock  maintains  a toll-free number for your questions.
The  number  is  (800)  227-7BFM  (7236).  We  encourage you to call us with any
questions  that you may have about your BlackRock funds and we thank you for the
continued trust that you place in our abilities.
