tisfaction of the Church of St. Michael, to hand over
these buildings in a completed condition, and to pay the cost of moving
from the old to the new buildings, before the old properties would be
turned over to the Railroad Company.

The house-wrecking was done by well-known companies under contract with the
Railroad Company. These companies took down the buildings and removed all
the materials as far as to the level of the adjacent sidewalks. The
building materials became the property of the contractors, who usually paid
the Railroad Company for the privilege of doing the house-wrecking. The
work was done between April and August, 1906, but the buildings of the
Church of St. Michael were torn down between June and August, 1907.

The bricks were cleaned and sold directly from the site, as were
practically all the fixtures in the buildings. The stone fronts were broken
up and left on the premises. Some of the beams were sold on the premises,
but most of them were sent to the storage yards. Some of the lath and
smaller timber was sold for firewood, but most of it was given away or
burned on the premises.

_Contracts and Agreements._--The main contract, awarded to the New York
Contracting Company-Pennsylvania Terminal on April 28th, 1906, included
about 502,000 cu. yd. of excavation (about 90% being rock), 17,820 cu. yd.
of concrete walls, 1,320,000 lb. of structural steel, 638,000 ft., B.M., of
framed timber, etc., etc.

This contract was divided into two parts: "Work In and Under Ninth Avenue"
and "Work Between Ninth and Tenth Avenues," and unit prices were quoted for
the various classes of work in each of these divisions. The prices quoted
for excavation included placing the material on scows supplied by the
Railroad Company at the pier at the foot of West 32d Street, on the North
River; there was a clause in the contract, however, by which the contractor
could be required to make complete disposal of all excavated material at an
additional unit price, and this clause was enforced on January 1st, 1909,
when about 94% of the excavation had been done.

For the purpose of disposing of the excavated material in the easterly
portion of the Terminal, the New York Contracting Company-Pennsylvania
Terminal had excavated under Ninth Avenue a cut which came to the grade of
32d Street about midway between Ninth and Tenth Avenues, and a trestle was
constructed from this point over Tenth Avenue and thence to the disposal
pier at
