November 1st the working force at this point,
including one resident civil engineer, was 103
At this point there is one engine of 100-horse power and one of 40-horse
power, and one compressor having four cylinders of a diameter of 13
inches and 24 inches stroke. The West heading from this shaft was
advanced 293 feet, and the East heading 1,042, on the first day of
December, 1866. The progress for the year ending November 1, 1866, at
the heading at this point was 636.7, being a fraction over 53 feet per
month. For the last four months, ending December 1, 1866, the progress
was 322.1, being a fraction over 64 feet per month, which exceeds by
four feet per month the highest estimate for hand-drilling by the
engineers in 1862, and by thirty and one-third feet the estimate of Mr.
Latrobe. The progress of the work at this heading during the last six
months, making allowance for the influx of water in November, having
exceeded the highest estimate for hand-drilling, should be regarded as
evidence alike of the skill of the miners and the good management of the
engineer and his subordinates.

=======================================
The West heading at this shaft was at first driven 6 feet by 11. It has
been found advisable to enlarge it to the dimension of 10 feet 6 inches
by 15 feet. This work has been performed by contract. The first letting
was at the rate of four dollars per cubic yard, the State furnishing the
materials used and removing the stone. The contractors at this rate
could not pay their expenses. It was raised to six dollars per yard
which was found not to pay, and in July the price was advanced to seven
dollars and fifty cents. The State pay the men, charging the same to the
contractors, and keep their time. Good progress is made and the work is
done to the satisfaction of the engineer.
The East heading at this point was being enlarged also by contract, from
6 feet by 15, to 10-1/2 by 15. The work commenced on the 15th of July,
1866; the price paid is seven dollars per cubic yard; the contractors
load their own stone and also that coming from the heading. The State
provides the materials used, and hoist the stone to the surface. While
the work of the miners at the East heading and of the contractors upon
both enlargements was progressing in a very satisfactory mariner, the
whole was arrested by an unexpected and somewhat sudden influx of
