beneath. These bents were placed 12 ft. on centers, with one 8 by 16-in.
stringer under each rail, and one 6 by 16-in. jack-stringer supporting
the overhang of the floor on either side.

The bents along the New York Central freight shed had but two posts of
12 by 14-in. yellow pine varying from 26 ft, to 31 ft. 9 in. from center
to center; they had double caps of 12 by 14-in. yellow pine on edge, no
bottom sills or bracing, and the vibration and wind pressure were taken
care of by the top bracing and anchorage, as shown by Bent "_G_," on
Fig. 6.

PLANT FOR DISPOSAL OF EXCAVATED MATERIALS PIER NO. 72 N.R.]

The method of erection was as follows: An excavation was made on the
line of each post, 4 ft. deep and from 4 to 5 ft. square, depending on
whether it was for a single or reinforced post; 6 in. of concrete was
placed in the bottom, and on this were laid, at right angles to the
center of the trench, three 8 by 12-in. timbers varying in length with
the excavation from 3 to 4 ft. To these timbers was drifted one 12 by
12-in. timber of the same length as those in the bottom row, but at
right angles to them. Elevations were then taken on top of the 12 by
12-in. timber, and the bent was framed complete and of correct height.
The framing was done south of the line of the trestle and west of the
freight-house. The framed bents were picked up by a small two-boom
traveler carrying two double-drum, electric, hoisting engines, and run
forward into position. A hole had previously been made in the metal
gutter and canopy of the freight-house, by an experienced roofer, and
in the freight platform underneath, and, as soon as the bent had been
