Report of Independent Registered Public Accounting Firm



To the Board of Directors and Shareholders of Adams Natural Resources
Fund, Inc.:

In planning and performing our audit of the financial statements of
Adams Natural Resources Fund, Inc. ("the Company") as of and for the
year ended December 31, 2016, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), we
considered the Company's internal control over financial reporting,
including controls over safeguarding securities, as a basis for
designing our auditing procedures for the purpose of expressing our
opinion on the financial statements and to comply with the
requirements of Form N-SAR, but not for the purpose of expressing an
opinion on the effectiveness of the Company's internal control over
financial reporting. Accordingly, we do not express an opinion on the
effectiveness of the Company's internal control over financial
reporting.

The management of the Company is responsible for establishing and
maintaining effective internal control over financial reporting. In
fulfilling this responsibility, estimates and judgments by management
are required to assess the expected benefits and related costs of
controls. A company's internal control over financial reporting is a
process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted
accounting principles. A company's internal control over financial
reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of the assets of the
company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that
receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the
company; and (3) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use or disposition of a
company's assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to
the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or
procedures may deteriorate.

A deficiency in internal control over financial reporting exists when
the design or operation of a control does not allow management or
employees, in the normal course of performing their assigned
functions, to prevent or detect misstatements on a timely basis. A
material weakness is a deficiency, or a combination of deficiencies,
in internal control over financial reporting, such that there is a
reasonable possibility that a material misstatement of the Company's
annual or interim financial statements will not be prevented or
detected on a timely basis.

Our consideration of the Company's internal control over financial
reporting was for the limited purpose described in the first paragraph
and would not necessarily disclose all deficiencies in internal control
over financial reporting that might be material weaknesses under
standards established by the Public Company Accounting Oversight Board
(United States). However, we noted no deficiencies in the Company's
internal control over financial reporting and its operation, including
controls over safeguarding securities, that we consider to be material
weaknesses as defined above as of December 31, 2016.

This report is intended solely for the information and use of
management and the Board of Directors of Adams Natural Resources 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.
