diversified  investment  company.  The  Corporation  is   an
internally-managed  fund  emphasizing  petroleum  and  other
natural  resource investments. The investment objectives  of
the  Corporation are preservation of capital, the attainment
of  reasonable  income from investments, and an  opportunity
for capital appreciation.

Security  Valuation-Investments  in  securities  traded   on
national  security exchanges are valued at the last reported
sale  price  on  the day of valuation. Over-the-counter  and
listed  securities for which a sale price is  not  available
are   valued  at  the  last  quoted  bid  price.  Short-term
investments  (excluding  purchased options)  are  valued  at
amortized cost. Purchased and written options are valued  at
the last quoted asked price.

For  federal  income  tax purposes, the identified  cost  of
securities  at  March  31,  2007 was  $379,439,805  and  net
unrealized  appreciation aggregated $482,341,243,  of  which
the  related  gross unrealized appreciation and depreciation
were $483,421,998 and $1,080,755, respectively.

8. PORTFOLIO SECURITIES LOANED
The  Corporation  makes  loans  of  securities  to  brokers,
secured  by  cash deposits, U.S. Government  securities,  or
bank  letters  of  credit.  The  Corporation  accounts   for
securities  lending  transactions as secured  financing  and
receives  compensation in the form  of  fees  or  retains  a
portion  of interest on the investment of any cash  received
as  collateral.  The Corporation also continues  to  receive
interest  or dividends on the securities loaned.  The  loans
are  secured at all times by collateral of at least 102%  of
the  fair  value  of  the  securities  loaned  plus  accrued
interest.  Gain  or  loss in the fair  value  of  securities
loaned  that may occur during the term of the loan  will  be

Item 2.  CONTROLS AND PROCEDURES.

Conclusions  of principal officers concerning  controls  and
procedures:

(a)  As of April 30, 2007, an evaluation was performed under
the  supervision and with the participation of the  officers
of  Petroleum  &  Resources Corporation (the "Corporation"),
including   the  principal  executive  officer   ("PEO") and

Corporation's   disclosure  controls  and  procedures   were
reasonably  designed so as to ensure: (1)  that  information

relating to the Corporation is made known to the PEO and PFO
as  appropriate to allow timely decisions regarding required
disclosure.

Corporation's internal control over financial reporting  (as
defined  in Rule 30 a-3(d) under the Investment Company  Act
of  1940  (17  CFR  270.30a-3(d)) that occurred  during  the
Corporation's  last  fiscal  quarter  that  have  materially
affected, or are reasonably likely to materially affect, the
Corporation's internal control over financial reporting.
