PRELIMINARY NOTE

         The persons filing this Amendment No. 2 are (i) Tweedy, Browne Company
LLC ("TBC"), a Delaware limited liability company, and (ii) TBK Partners, L.P.
("TBK"), a Delaware limited partnership. This Amendment No. 2 amends a Statement
on Schedule 13D filed by TBC and TBK dated June 17, 1997.( the "Statement"). The
filing of this Amendment No. 2 should not be deemed an admission that TBC and
TBK comprise a group within the meaning of Section 13(d) (3) of the Securities
and Exchange Act of 1934, as amended (the "Act").

         This Amendment No. 2 relates to the Common Stock, $.01 par value (the
"Common Stock"), of Oil-Dri Corporation of America (the "Company"), which, to
the best knowledge of the persons filing this Amendment No. 2, is a company
organized under the laws of Delaware, with its principal executive offices at
410 North Michigan Avenue, Chicago, Illinois 60611.

         This Amendment No. 2 contains information regarding shares of Common
Stock that may be deemed to be beneficially owned by TBC. Such shares are held
in the accounts of various customers of TBC, with respect to which it has
obtained sole or shared voting power.

         Other than as set forth below, to the best knowledge of TBC and TBK ,
there has been no material change in the information set forth in response to
Items 1,2,3,4,6 and 7 of the Statement, as amended. Accordingly, those Items are
omitted from this Amendment No. 2.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a) As of the date hereof, TBC may be deemed to be the beneficial owner
of an aggregate of 418,467 shares of Common Stock, which constitutes
approximately 7.65% of the 5,470,252 shares of Common Stock which TBC believes
to be the total number of shares of Common Stock outstanding. The TBC Shares are
held in the TBC Accounts.

         As of the date hereof, TBK may be deemed to be the beneficial owner of
an aggregate of 14,655 shares of Common Stock, which constitutes approximately
0.26% of the 5,470,252 shares of Common Stock which TBK believes to be the total
number of shares of Common Stock outstanding.

         Also included in the TBC Accounts are 185 shares of Common Stock held
in a charitable foundation of which Christopher H. Browne is a trustee. Mr.
Browne is a member of TBC and a general partner in TBK.

         Each of TBC and TBK disclaims that it is the beneficial owner of any of
the shares of Common Stock held in the TBC Accounts. The aggregate number of
shares of Common Stock with respect to which TBC and TBK could be deemed to be
the beneficial owner as of the date hereof, is 433,122 shares, which constitutes
approximately 7.91% of the 5,470,252 shares of Common Stock, which the filing
persons believe to be the total number of shares of Common Stock outstanding,
but nothing contained herein shall be construed as an admission that TBC is the
beneficial owner of any of the TBC Shares.

         The aggregate number of shares and percentage of Common Stock with
respect to which each of the General Partners and Members may be deemed to be
the beneficial owner by reason of his being a general partner of TBK, or a
member of TBC, is 433,122 shares, which constitutes approximately 7.91% of the
5,470,252 shares of Common Stock outstanding. The aggregate number of shares and
percentage of Common Stock with respect to which Thomas P. Knapp may be deemed
to be a beneficial owner by reason of his being a general partner of TBK is
14,655 shares of Common Stock which constitutes 0.26% of the 4,470,252 shares of
Common Stock outstanding. However, nothing contained herein shall be construed
as an admission that any of the General Partners or Thomas P. Knapp is the
beneficial owner of any shares of Common Stock, except as set forth herein as
expressly and admittedly being beneficially owned by a particular General
Partner or Thomas P. Knapp.

         Each of TBC and TBK disclaims beneficial ownership of Common Stock held
by the other. Except as described herein, to the best knowledge of TBC and TBK ,
no person who may be deemed to comprise a group with any of TBC and TBK, or any
other person named in Item 2 of the Statement, beneficially owns any shares of
Common Stock.

         (b) TBC has investment discretion with respect to 418,467shares of
Common Stock held by the TBC Accounts and has sole power to dispose or direct
the disposition of all of such shares. Of these shares of Common Stock, TBC has
sole power to vote or to direct the voting of 470,012 shares of Common Stock
held in certain TBC Accounts.

   6

         Each of the Members of TBC, solely by reason of their positions as
such, may be deemed to have (i) shared power to dispose of or to direct the
disposition of all of the shares of Common Stock held in the TBC Accounts; and
(ii) shared power to vote or direct the vote of 470,012 shares of Common Stock
held in certain TBC Accounts.

direct the disposition of the TBK Shares.
