To the Shareholders and Board of Directors of
The BlackRock Income Trust, Inc.:
In planning and performing our audit of the
financial statements of The BlackRock Income
Trust, Inc. (the "Trust") for the year ended
October 31, 1997 (on which we have issued our
report dated December 12, 1997), we considered its
internal control structure, including procedures
for safeguarding securities, in order to determine
our auditing procedures for the purpose of
expressing our opinion on the financial statements
and to comply with the requirements of Form N-SAR,
not to provide assurance on the internal control
structure.
The management of the Trust is responsible for
establishing and maintaining an internal control
structure. In fulfilling this responsibility,
estimates and judgments by management are required
to assess the expected benefits and related costs
of internal control structure policies and
procedures. Two of the objectives of an internal
control structure are to provide management with
reasonable, but not absolute, assurance that
assets are safeguarded against loss from
unauthorized use or disposition and that
transactions are executed in accordance with
management's authorization and recorded properly
to permit preparation of financial statements in
conformity with generally accepted accounting
principles.
Because of inherent limitations in any internal
control structure, errors or irregularities may
occur and not be detected. Also, projection of
any evaluation of the structure to future periods
is subject to the risk that it may become
inadequate because of changes in conditions or
that the effectiveness of the design and operation
may deteriorate.
Our consideration of the internal control
structure would not necessarily disclose all
matters in the internal control structure that
might be material weaknesses under standards
established by the American Institute of Certified
Public Accountants. A material weakness is a
condition in which the design or operation of the
specific internal control structure elements does
not reduce to a relatively low level the risk that
errors or irregularities in amounts that would be
material in relation to the financial statements
being audited may occur and not be detected within
a timely period by employees in the normal course
of performing their assigned functions. However,
we noted no matters involving the internal control
structure, including procedures for safeguarding
securities, that we consider to be material
weaknesses as defined above as of October 31,
1997.
This report is intended solely for the information
and use of management and the Securities and
Exchange Commission.
