a total of $50 cubic feet per minute The
air pressure in pounds per square inch is
100, and the weight of the machine is aS. eco
pounds. II the reader gets any intelligent
idea whatever from this description, he
must understand that this air compressor
furnishes the power for the fifteen drills
which arc at work perforat:ng the rock
both at the mouth of the shaft and at the
mouth OF the tunnel. The air goes direct
~ from the compressor to receiving
tank, 4I2x1e feet. 1t is thence distributed
by pipes to the mouth of the shaft and 10
the mouth of the tunnel, where he drills
are st work.
This pipe line, II carefully followed out.
is one of the most interesting objects
among the practical feats Of engineering
thus far accomplished under the sapervi-
sion Of Mr.. Reynolds. II extends from the
receiving tank to the shaft. and about 100

The drills themselves which are operated
by this compressed air are models OF nine
teenth century workmanship. and OF the
latest design. They are known az the
New Ingersol, 1895 model" Each of
them is of extra length. for'y-eieht inch
