Registration Statement on Form S-1

File No. 333-178376.

Ladies and Gentlemen:

Pursuant to Rule 461 under the Securities Act of 1933, as amended (the “Securities Act”), iShares^® Delaware Trust Sponsor LLC (the “Sponsor”), as sponsor on behalf of the registrant, iShares^® Dow Jones-UBS Roll Select Commodity Index Trust (the “Trust”), hereby requests that the effective date of the above-referenced Registration Statement be accelerated by the Securities and Exchange Commission (the “Commission”) so that the Registration Statement, as then amended, will become effective under the Securities Act at 9:00 a.m. ET on August 7, 2013 or as soon thereafter as practicable.

The Sponsor and the Trust hereby acknowledge that:

• should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;

• the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the registrant from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and

• the registrant may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

We request that we be notified of such effectiveness by a telephone call to Andrew Faulkner of Skadden, Arps, Slate, Meagher & Flom LLP at (212) 735-2853 and that such effectiveness also be confirmed in writing.

Very truly yours,
