Report of Independent Auditors
To the Shareholders and Board of Directors of
Dreyfus Municipal Money Market Fund, Inc.
In planning and performing our audit of the financial statements of Dreyfus
Municipal Money Market Fund, Inc. for the year ended May 31, 1999, 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 internal control.
The management of Dreyfus Municipal Money Market Fund, Inc. 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 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 specific 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
internal control and its operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above at May
31, 1999.
This report is intended solely for the information and use of the board of
directors and management of Dreyfus Municipal Money Market Fund, Inc. and the
Securities and Exchange Commission and is not intended to be and should not be
used by anyone other than these specified parties.
