RE: Nuveen Unit Trust, Series 3,
(the "Registrant")(File No. 333-23675)
Nuveen U.S. Treasury Trust, Series 3 (Short-Term) and
Nuveen U.S. Treasury Trust, Series 4 (Intermediate)
Gentlemen:
The Registrant is a unit investment trust for which a registration
statement on Form S-6 was filed and declared effective by the Commission on
November 5, 1997. The Registrant consists of four separate underlying series.
The subject registration statement included an English language prospectus
for each of the series which is being utilized in the offering of units of
the series. The Depositor intends to utilize, in addition to the English
language prospectus, a Spanish language translation of such prospectuses in
offering units of two of the series; the Nuveen U.S. Treasury Trust, Series 3
(Short-Term) and the Nuveen U.S. Treasury Trust, Series 4 (Intermediate)
(collectively, the "TREASURY TRUSTS"). Pursuant to Item 306 of Regulation
S-T, General Rules and Regulations for Electronic Filings, the Registrant
hereby represents that the Spanish language prospectuses for the Treasury
Trusts are fair and accurate translations of the English language
prospectuses contained in the registration statement filed with the
Commission pursuant to Rule 497(b) on November 7, 1997. In accordance with
Item 306 of Regulation S-T, a paper copy of the Spanish language prospectus
otherwise required to be filed shall be provided to the Commission upon
request.
Very truly yours,
NUVEEN UNIT TRUST, SERIES 3
