Report of Independent Accountants

To the Board of Trustees and Shareholders
of John Hancock Income Securities Trust

In planning and performing our audit of the financial statements of John Hancock
Income Securities Trust (the "Trust") for the year ended December 31, 2003, we
considered its internal control, including control activities 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 internal control.

The management of the Trust is responsible for establishing and maintaining
internal control. In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related costs of
controls. Generally, controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for external purposes that
are fairly presented in conformity with generally accepted accounting
principles. Those controls include the safeguarding of assets against
unauthorized acquisition, use or disposition.

Because of inherent limitations in internal control, errors or fraud may occur
and not be detected. Also, projection of any evaluation of internal control to
future periods is subject to the risk that controls may become inadequate
because of changes in conditions or that the effectiveness of their design and
operation may deteriorate.

Our consideration of internal control would not necessarily disclose all matters
in internal control 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 one or more
of the internal control components does not reduce to a relatively low level the
risk that misstatements caused by error or fraud 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
internal control and their operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above as of
December 31, 2003.

This report is intended solely for the information and use of the Board of
Trustees, management and the Securities and Exchange Commission and is not
intended to be and should not be used by anyone other than these specified
parties.

Global Custody Network The Bank of New York's network of subcustodians extends
to 101 markets worldwide, the largest number of markets offered by any
custodian. We continually review our network to ensure that it reflects the
changing global investment decisions of our clients. The Bank's dedicated,
regional network management team monitors local economic, political, regulatory,
and industry-related events, and keeps clients apprised of changes in the
investment climate of each market. Banks are selected for the network based on a
variety of criteria, such as compliance with worldwide regulatory requirements,
competitive pricing, general market reputation, SWIFT message capabilities,
securities lending support, credit ratings, overall banking relationship with
The Bank of New York and ability to consistently meet our clients' needs. Each
bank must meet a set of stringent performance standards prior to selection,
which are reexamined during quarterly reviews and frequent on-site visits,
ensuring that our clients are uniformly provided with the best subcustodian in
each market. In its last three annual reviews of subcustodian networks, GSCS
BenchmarksTM has ranked our network among the top two in both the Overall
Network and Major Markets categories. Our list of subcustodians is as follows:
