I, Malcolm R. Fobes III, certify that:

1.  I have reviewed this report on Form N-CSR of The Berkshire Funds;

2.  Based  on  my knowledge, this report does not contain any untrue statement
    of  a material fact or omit to state a material fact necessary to make the
    statements made, in light of the circumstances under which such statements
    were  made,  not  misleading  with  respect  to the period covered by this
    report;

3.  Based  on  my  knowledge,  the  financial  statements, and other financial
    information  included  in  this  report,  fairly  present  in all material
    respects  the  financial  condition, results of operations, changes in net
    assets,  and  cash  flows  (if  the  financial  statements are required to
    include  a  statement of cash flows) of the registrant as of, and for, the
    periods presented in this report;

4.  The  registrant's  other  certifying  officer(s) and I are responsible for
    establishing and maintaining disclosure controls and procedures (as defin-
    ed in Rule 30a-3(c) under the Investment Company Act of 1940) and internal
    control  over  financial  reporting (as defined in Rule 30a-3(d) under the
    Investment Company Act of 1940) for the registrant and have:

    (a)  Designed  such  disclosure  controls  and  procedures, or caused such
         disclosure   controls   and  procedures  to  be  designed  under  our
         supervision,  to  ensure  that  material  information relating to the
         registrant, including its consolidated subsidiaries, is made known to
         us by others within those entities, particularly during the period in
         which this report is being prepared;

    (b)  Designed  such  internal  control over financial reporting, or caused
         such  internal  control over financial reporting to be designed under
         our supervision, to provide reasonable assurance regarding the relia-
         bility of financial reporting and the preparation of financial state-
         ments  for  external  purposes  in accordance with generally accepted
         accounting principles;

    (c)  Evaluated  the  effectiveness of the registrant's disclosure controls
         and procedures and presented in this report our conclusions about the
         effectiveness of the disclosure controls and procedures, as of a date
         within  90 days prior to the filing date of this report based on such
         evaluation; and

    (d)  Disclosed in this report any change in the registrant's internal con-
         trol  over financial reporting that occurred during the second fiscal
         quarter of the period covered by this report that has materially aff-
         ected, or is reasonably likely to materially affect, the registrant's
         internal control over financial reporting; and

5.  The  registrant's  other certifying officer(s) and I have disclosed to the
    registrant's auditors and the audit committee of the registrant's board of
    directors (or persons performing the equivalent functions):

    (a)  All significant deficiencies and material weaknesses in the design or
         operation  of  internal  control  over  financial reporting which are
         reasonably  likely  to  adversely  affect the registrant's ability to
         record, process, summarize, and report financial information; and

    (b)  Any fraud, whether or not material, that involves management or other
         employees  who  have  a significant role in the registrant's internal
         control over financial reporting.
