To the Board of Directors and Shareholders of
The BlackRock New Jersey Investment Quality
Municipal Trust Inc.
In planning and performing our audit of the
financial statements of The BlackRock New Jersey
Investment Quality Municipal Trust Inc. for the
year ended October 31, 1996 (on which we have
issued our report dated December 6, 1996), 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 BlackRock New Jersey
Investment Quality Municipal Trust Inc. 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,
1996.
This report is intended solely for the information
and use of management and the Securities and
Exchange Commission.
