A contract, dated August 24th, 1904, with the New York Contracting
Company-Pennsylvania Terminal, for the construction of sewers in Seventh
Avenue and in 32d and 33d Streets east of Seventh Avenue.

A contract, dated November 24th, 1908, with the New York Contracting
Company-Pennsylvania Terminal, for the construction of a 16-in. gas main
from Seventh Avenue and 32d Street to 34th Street, and thence to Eighth
Avenue.

All these contracts required that the excavated material be delivered on
board scows to be furnished by the company at the pier at the foot of
32d Street, North River. These scows were furnished and the material
was disposed of from that point by Henry Steers, Incorporated, under a
contract, dated August 9th, 1904, which called for the transportation to
and placing of all material so delivered in the Pennsylvania Railroad
Company's freight terminal at Greenville, N.Y.

The disposal of the excavated material was one of the principal features
of the work, and, under the above contract, material from those portions
of the Terminal site east of Seventh Avenue and west of Ninth Avenue,
and from all substructures work, was disposed of, as well as from the
constructions herein described. The problem differed from that presented
by the usual foundation excavations in New York City in magnitude only,
