Form 10-K for the year ended October 28, 2005

Item 9A. Controls and Procedures, page 23

1. We note your disclosure that "disclosure controls and
procedures
were effective to ensure that information [you] are required to
disclose in the reports that [you] file under the Exchange Act is
recorded, processed, summarized and reported within time periods
specified in Securities and Exchange Commission rules and forms."
Please revise future filings to clarify, if true, that your
officers
concluded that your disclosure controls and procedures are also
effective to ensure that information required to be disclosed in
the
reports that you file or submit under the Exchange Act is
accumulated
and communicated to your management, including your chief
executive
officer and chief financial officer, to allow timely decisions
regarding required disclosure.  See Exchange Act Rule 13a-15(e).

arrangements in a separately captioned subsection of MD&A as
required
by Item 303(a)(4) of Regulation S-K. Also, make the detailed
disclosures required by paragraphs (a)(4)(i) of this Item, to the
extent necessary to understand your off-balance sheet arrangements

line in fiscal 2004. If you recognize a gain or loss that is not a
component of an entity, you should include that amount in income
from
continuing operations before income taxes. See paragraph 45 of
SFAS

6. In periods where you consummate a material business

Leach

financial statements for this acquisition or show us that they
were
not required.  Also please tell us your consideration of Rule 3-05

	 We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filing to be certain that the
filing includes all information required under the Securities
Exchange Act of 1934 and that they have provided all information
investors require for an informed decision.  Since the company and
its management are in possession of all facts relating to a
company`s
disclosure, they are responsible for the accuracy and adequacy of
the
disclosures they have made.

	In connection with responding to our comments, please
provide,
in writing, a statement from the company acknowledging that:

* the company is responsible for the adequacy and accuracy of the
disclosure in the filing;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action
with
respect to the filing; and

proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

      In addition, please be advised that the Division of
Enforcement
has access to all information you provide to the staff of the
Division of Corporation Finance in our review of your filing or in
