INSPECTORS OF MINES. 101
Middle Port.— Richard Holohan, Operator.
The colliery is situated east of Middle Port, on the estate of P. W.
Sheafer. It consists of a drift opened on a 45° north dip of the Palmer
seam. Its gangway is 200 yards, with 6 breasts working, &c, in 3^ feet
of coal ; the superstrata is a flaty shoal, and dangerous in mining, but the
work is secure and safe to work in.
Ventilation is produced by natural currents, scarcely sufficient to dilute
the powder smoke, which sickens miners whenever it comes in contact
with them in their work. 10 hands are employed in mining and preparing
coal for family use.
