Re:  The John W. Henry & Co./Millburn LP file no. 18215

Dear Ms. Luckey:

We have previously responded to your May 10 inquiry regarding items 2, 4 and
6. We apologize for the delay in responding in writing to your other
inquiries.

Regarding item 1, Control and Procedures, we acknowledge that our phraseology
was incorrect and the Company will revise Item 9a - Controls and Procedures
to indicate that the Company performed an evaluation of effectiveness of the
design and operations of its disclosure controls and procedures "as of the
period covered by the report" in future filings. Please respond if this is
not acceptable.

Regarding items 3 and 5, Independent Auditor's Report, although the ML
Millburn LLC and the ML JWH Financial and Metals Portfolio LLC are
incorporated by reference they are not themselves public entities and we
contend that the audit opinions should continue to fall under Generally
Accepted Auditing Standards and not the PCAOB standards for public companies.


If you have any further inquiries, you may contact me directly at
609-282-6091 or via email at barbra_kocsis@ml.com. You may also contact the
Chief Financial Officer, Michael Pungello.

Regards
