2-in. pipe per day. The average was much less,
owing to a variety of causes. At the end, the railway company added to
the contractor's force, and laid the last 10 miles of pipe in 7 days,
there being a half dozen separate gangs at work.

Along the railway, the day's record on wood pipe was 4,000 ft. of 11-in.,
6,200 ft. of 7-1/2-in. and 8345 ft. of 3-1/2-in, pipe laid by a gang of
eight men after the pipe was distributed along the trench. These eight
men, of whom five were Americans, laid 76 miles of pipe, and became
expert. Their operation was like the working of a clock.

On the 12-in. iron pipe, the regular day's work was 96 joints, or 1,152
ft. of pipe laid and caulked. The record was 1,644 ft. Two gangs laid
101,300 lin. ft. in 60 days. Such a gang consisted of 1 foreman, 1
inspector, 8 caulkers, 4 yarners, 1 melter, 1 pourer, 1 helper, and 10
men putting pipe into the trench.

_Cost Data_.--The pipe from Bonito to the railway was laid by contract.
The price was 18 cents per lin. ft. laid and back-filled from the
