96 ANNUAL REPORT OF THE
east panel, 100 yai-ds, with 5 breasts, working in 8 feet of coal, with mining
rims of TO yards. An egress and ingress out-let is in course of construction.
These breasts are flanked by 6 yard pillars.
Ventilation is produced by means of a furnace, the slope being used as
a downcast, and the air conducted into the face of working places ; thence
back to the out-let. The character of the work done is safe—ventilation
only moderate.

No. 33. Bull Run Tunnel.— Lehigh Coal and Navigation Company,
Operators.
This colliery is situated 2 miles east of Tamaqua, on the estate of said
corporation. It consists of a tunnel driven North 331 yards to the E seam.
All of this level has been worked out. A slope 70 yards deep has been
sunk at the end of the tunnel on a 40° south dip, with 2 panels opened.
Its east panel is 1,100 yards, with — breasts working in it. Its west
gangway' is 708 yards, with 17 breasts working. A new trial slope is in
course of sinking—30 yards of which is completed. I consider this one
of our safest collieries, and is the best managed in the district. The mine
evolves fire-damp.
Ventilation is produced by a 20 -horse power fan. The tunnel is used as
an intake. The air is conducted in spits into the face of the working
places travesing them, and going out to the fan, giving satisfactory results.
