Dear Mr. Sackner:

      We have reviewed your filing and have the following
comments.
We have limited our review to only your financial statements and
related disclosures and will make no further review of your
documents.  Where indicated, we think you should revise your
document
in response to these comments.  If you disagree, we will consider
your explanation as to why our comment is inapplicable or a
revision
is unnecessary.  Please be as detailed as necessary in your
explanation.  In some of our comments, we may ask you to provide
us
with supplemental information so we may better understand your
disclosure.  After reviewing this information, we may or may not
raise additional comments.

      Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comment or on any other
aspects
of our review.  Feel free to call us at the telephone numbers
listed

Form 10-KSB for the fiscal year ended July 31, 2004

Item 14.  Controls and Procedures - Page 22

1. We note your disclosure that your principal executive officer
and
principal financial officer have evaluated your disclosure
controls
and procedures as of a date within 90 days before the filing date
of
your annual report.  Please amend your filing to disclose
management`s conclusion regarding the effectiveness of your
disclosure controls and procedures as of the end of the period
covered by the annual report.  Refer to Item 307 of Regulation S-K
and Part III.F of Management`s Reports on Internal Control Over
Financial Reporting and Certification of Disclosure in Exchange
Act
Periodic Reports, Release No. 33-8238, available on our website at
www.sec.gov/rules/final/33-8238.htm.  Please note this comment
also
applies to your Form 10-QSB as of October 31, 2004.

2. We note your statement that the chief executive officer and
company comptroller have "determined" that the company`s
disclosure
controls and procedures are "designed to ensure that material
information relating to the Company is made known to them,
particularly during the period in which this Form 10-KSB was being
prepared."  It does not appear that your certifying officers have
concluded that your disclosure controls and procedures are
effective.
Please revise to address your officers` conclusions regarding the
effectiveness of your disclosure controls and procedures.  In
addition, please note that the definition of disclosure controls
and
procedures is included in Rule 13a-15(e) of the Exchange Act.  If
you
wish to include the definition with your conclusion, please ensure
the definition is consistent with the definition included in Rule
13a-15(e) of the Exchange Act.  Please note this comment also
applies
to your Form 10-QSB as of October 31, 2004.

3. We note your disclosure that "there have been no significant
changes in the Company`s internal controls or in other factors
that
could significantly affect internal controls subsequent to the
date
of their evaluation."  Revise to state clearly if there were any
changes in your internal control over financial reporting that
occurred during the most recent quarter that have materially
affected, or are reasonably likely to materially affect, your
internal control over financial reporting.  Please note this
comment
also applies to your Form 10-QSB as of October 31, 2004.

Exhibit 31 - Certificates of the Chief Executive Officer and Chief
Accounting Officer

4. We note that the certifications filed as Exhibit 31.1 and

certifications may not be changed in any respect, except for the
modifications temporarily permitted to be made to the fourth
paragraph of the certification required to be filed as Exhibit
31.1
pursuant to Part III.E of Release No. 8238. Accordingly, please
file
amendments to your Forms 10-KSB and 10-QSB that include the entire
filings together with the certifications of your current CEO and
acting CFO in the form currently set forth in Item 601(b)(31) of
Regulation S-B.
