Report of Independent Registered Public Accounting Firm

To the Board of Directors
The Dreyfus Third Century Fund, Inc.

We have examined management's assertion, included
in the accompanying Management Statement Regarding
Compliance with Certain Provisions of the Investment
Company Act of      1940 that
The Dreyfus Third Century Fund, Inc.
(the "Company") complied with the requirements of
subsections (b) and (c) of Rule 17f-2 under the Investment
Company Act of 1940 ("the Act") as of June 30, 2013.
Management is responsible for the Company's compliance
with those requirements.  Our responsibility is to express
an opinion on management's assertion about the Company's
compliance based on our examination.

Our examination was conducted in accordance with the
standards of the Public Company Accounting
Oversight Board (United States) and, accordingly, included
examining, on a test basis, evidence about the Company's
compliance with those requirements and performing such
other procedures as we considered necessary in the
circumstances. Included among our procedures were the
following tests performed as of June 30, 2013,
and with respect to agreement of security and similar
investment purchases and sales, for the period from
August 31, 2012 (the date of our last examination) through
June 30, 2013:

Count and inspection of all securities and similar
investments located in the vault of The Bank of New York
Mellon in New York and London, if any, without prior notice
to management;

Confirmation of all securities and similar investments
held by institutions in book entry form (i.e., the Federal
Reserve Bank of Boston, the Depository Trust Company
and various sub-custodians);

Reconciliation of all such securities and similar investments
to the books and records of the Company and
The Bank of New York Mellon;

Confirmation of all securities hypothecated, pledged, placed
in escrow, or out for transfer with brokers, pledgees, transfer
agents or securities lending administrators;

Confirmation of all repurchase agreements, if any, with
brokers/banks or to documentation of corresponding subsequent
cash receipts and agreement of underlying collateral with
The Bank of New York Mellon's records;

Agreement of pending purchase activity as of June 30, 2013
to documentation of subsequent broker statements;

Agreement of Dreyfus Family of Funds' (the "Funds") trade
tickets for 5 security purchases and 5 security sales
or maturities for the period from September 1, 2012 through
June 30, 2013, to the books and records of the Funds
noting that they had been accurately recorded and
subsequently settled;

We believe that our examination provides a reasonable
basis for our opinion. Our examination does not provide
a legal determination on the Company's compliance with
specified requirements.

In our opinion, management's assertion that
The Dreyfus Third Century Fund, Inc.
complied with the requirements of subsections (b) and (c) of
Rule 17f-2 of the Act as of June 30, 2013
with respect to securities and similar
investments reflected in the investment account of the
Company is fairly stated, in all material respects.

This report is intended solely for the information and use of
management and the Board of Directors of
The Dreyfus Third Century 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.
