Washington, D.C. 20549 Re: Narragansett Insured Tax-Free Income Fund (CIK 0000888955) Form N-14 Registration Statement (No. 333-153073) Filed on August 19, 2008 Ladies and Gentlemen: On behalf of Narragansett Insured Tax-Free Income Fund (the "Fund"), and pursuant to Rule 477 under the Securities Act of 1933, this letter constitutes application on Form RW to withdraw Registration Statement No. 333-153073 on Form N-14, filed with the Commission on August 19, 2008 (Accession No. 0000888955-08000023)(the "August 19 Filing"). The August 19 filing was intended to be a pre-effective Amendment to a registration statement filed on behalf of the Fund on July 11, 2008 and was inadvertently filed on Form N-14 instead of Form N-14/A. The pre-effective amendment has now been properly filed on Form N-14/A. Therefore, it is appropriate to withdraw the August 19 Filing. Please contact me or my partner Robert Jones at the above telephone number, 212-818-1110, with any questions. Very truly yours, /s/ Arthur Dudley II Arthur Dudley II
