Ladies and Gentlemen:

On December 30, 2004, the Post-Effective Amendments referenced above (the
"Amendments") were filed pursuant to paragraph (a) of Rule 485 in connection
with the annual registration statement update for the Registrants. The
amendments were filed to update the Amendments filed on October 26, 2004 to add
disclosure regarding market timing and fund portfolio holding dissemination
pursuant to the recently adopted amendments to Form N-1A, and to incorporate the
Staff's comments on such disclosure.

Pursuant to Rule 461(a) under the Securities Act of 1933, as amended, each
Registrant and John Hancock Funds, LLC, principal underwriter of the
Registrants, each respectfully requests that the effective date of the
Amendments be accelerated to January 1, 2005, or as soon thereafter as possible.

Acceleration is being requested so that the effective date of the Amendments
will meet the required effective date of the Registrants' annual registration
statement updates.

If you have any questions or comments, please contact Brian Langenfeld at (617)
375-1722.

                                    Sincerely,
