Here we have a section of the seam of coal worked at the 
Lithgow Valley Company’s Colliery, situated about 90 miles by 
rail from Sydney and the harbour of Port Jackson. Their 
property consists of 1,116 acres. (See letter on plan No. 4). 
The coal is here about 10 feet 21 inches in thickness, and js 
worked by an adit driven into the seam, which is connected w'ith 
the Great Western Eailvvay by a tramway less than I a mile in 
length. It is a splint coal, which has been found well suited for 
steam, household, smelting, gas, blacksmith, and other purposes, 
dips about 1 in 20 to the east, and from its hard splinty nature 
has been found to bear carriage w^ell, as it does not readily break 
and form itself into slack. When I visited this colliery last they 
were opening out the upper thick coal for the purpose of making 
coke. It is a more bituminous coal, but is very full of bands. 
The quantity of coal sold from this colliery in 1874 was 18,000 
tons, valued at £5,400, and the average miinher of men daily 
employed when the colliery was at work \vas twenty-five. Mr, 
Douglas is the Colliery Manager.
