ical of any colliery we have ever seen. The openings (such as tunnels,
airways, traveling- ways and outlets) not being completed, prevents me
from giving a complete description of this colliery this year, but I will
be able to do so next year, all being well.
At Springdale colliery, belonging to Lentz, Lilly & Co., a subterraneous
slope has been sunk, and a tunnel driven across the basin from
the north dip of the Buck Mountain vein to the south dip, a distance of
eight hundred feet, cuttiug the north dip of the top and bottom splits
of the Mammoth vein, Skidmore and Seven-foot, and again cutting the
same veins on the south dip. Thickness of veins are as follows
North dip. South dip.
Mammoth | Bottom split, . . 3' thick. Bottom split, . 4' thick,
I Top split, ... 12' thick. Top split, ... 16' thick.
Skidmore, ... 4' thick. Skidmore, ... 6' thick.
Seven-foot, ... 7' thick. Seven-foot, . . 5' 6' tliick.
Buck Mountain, 12' thick. Buck Mountain, 16' thick.
A shaft was sunk 5'x4|'xl96' deep from surface (connecting with head
of subterranean slope), through which the wire ropes from engine drum
pass down to hoist the cars. The engines are direct acting, cylinders
thirty inches, stroke forty-eight inches. The hoisting arrangements are
very satisfactory and sixty cars an hour can be hoisted. An airway was
driven up in the Skidmore vein, and the sixteen-foot fan has been
moved from the Buck Mountain water level drift to the Mammoth vein
water level drift on the north dip, which has considerably increased the
volume of air. Several outlets have been constructed so that the workmen
have ready means of ingress and egress to all the veins in connec-
tion with this colliery.
At Rehley's Run the breaker has undergone extensive repairs. A new
double acting pump, with sixteen-inch j)lunger, built by Garner & Sons,
Ashland, has been put in place at the second lift below water level.
The main hoisting slope has been retimbered at intervals. The West
Mammoth vein gangway has been partially retimbered and log cribbings
have been built in many of the old chutes to strengthen the surroundings
of the gangway. Mr. Baird, the superintendent, takes special
pains in keeping the outside, as well as the inside, departments in first-
class condition.
At William Penu colliery a new slope is being sunk in the Buck
Mountain vein and will terminate six hundred feet below the level of No.
2 subterranean slope, still leaving about two lifts in the basin. A tun-
nel will be driven from the Buck Mountain (at the termination of this
six hundred feet) to the Mammoth vein. The entire length of this new
slope will be fifteen hundred feet to the saw mill or first water level
drift. The Buck Mountain vein is nine feet thick and has an excellent
hard top. The slope is sunk sixteen feet wide and requires no timber.
A new slope is sunk in the bottom split of Mammoth vein in a local
