They use a patent Sercombe kiln, with eighteen chambers. For brick burning.
The Hermitage Colliery.
This is one of the collieries of the Lithgow Valley Colliery Company, and is under the general management of Mr. J. Campbell. In many respects it is a duplicate of the Lithgow Valley Colliery. The colliery is worked from tunnels driven from the outcrop ; the coal is extracted by the ordinary pillar and bord system, but the winning of pillars has not yet been Fig. 41. Tension Pulley.
commenced. Th...e hauling is done by an endless rope, which rests in jockeys- above the skips, but only one size of jockey is employed, for as no end gatej is on the skip, a place is pro- vided at either end for the jockey, which can be changed from one to the other according to which way the skip is travelling, so there is not the- same fear of the skip tipping up when empty, as at the Lithgow Valley Colliery. The jockey con- sists of an iron rod, with a hook on the top at one side, for the endless rope to rest in.
