^ free-burning bituminous coal, used for household, steam, 
smelting, gas coking, and blacksmith purposes, and has an 
average specific gravity of 1-23 to r29, tL mine being situated 
about nine miles from the Newcastle Harbour. There are several 
shatts sunk to this coal on the Company’s 9,000 acres of land, 
but they are at the present time only using one for raising and 
ding coal. This shaft is 185 feet in depth, and 14 feet in 
It has a GO h.-p. engine, which lifted an average 
1874 ^ tours out of the mine in 
1 quantity raised in one day of nine hours was 
i 270 tons, tor which the manager deserves very great praise, as 
it would be impossible to raise such a large daily quantity at one 
shaft, unless everything above and below ground was well and 
systematically laid and carried out. They have two underground 
traction engines, one of 40 h.-p., and the other 30 h.-p. ; one 
sLft’^' Copper-engine, and one 15 h.-p. engine for sinking 
30 horses, 400 miners, and 200 labourers, wheelers, and 
mechanics, employed daily in 1874, when the pit was working. 
They raised 240,000 tons of coal, valued at £163,000, in 1874.
