INDEPENDENT AUDITORS REPORT
The Board of Directors
Seligman Frontier Fund, Inc.
In planning and performing our audit of the financial statements of Seligman
Frontier Fund, Inc. (theFund) for the year en September 30, 1998 (on which we
have issued our report dated October 30, 1998), 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, and
not to provide assurance on the Funds internal control.The management of the
Fund 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 entitys
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 it
may be become inadequate because of changes in conditions or that the
effectiveness of the design and operation may deteriorate.Our consideration of
the Funds 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
errors 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 the Funds internal control and its operation,
including controls for safeguarding securities, that we consider to be material
weaknesses as defined above as of September 30, 1998.This report is intended
solely for the information and use of management, the Board of Directors of
Seligman Frontier Fund, Inc., and the Securities Exchange Commission.
