[DESCRIPTION]REPORT OF INDEPENDENT ACCOUNTANTS
To the Trustees of Loomis Sayles Investment Trust:
In planning and performing our audit of the financial statements and financial
highlights (hereinafter referred to as "financial statements") of the Loomis
Sayles Investment Trust [consisting of Loomis Sayles California Tax-Free
Income Fund, Loomis Sayles Core Fixed Income Fund, Loomis Sayles Core Growth
Fund, Loomis Sayles Fixed Income Fund, Loomis Sayles High Yield Fixed Income
Fund, Loomis Sayles Intermediate Duration Fixed Income Fund, and Loomis Sayles
Investment Grade Fixed Income Fund (collectively known as the "Trust")] for
the nine month period ended September 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,
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 judgements
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, error 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 become inadequate because
of changes in conditions or that the effectiveness of the 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 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
Trustees of the Trust and the Securities and Exchange Commission.
