In Mr. Hughes' report assays of samples from other localities are also given.
The
Warora coal is deficient in fixed carbon, a larger percentage of which
is essential where great heating power is required. It also is
deficient in combustible volatile gases. Pisgaon coal, however,
contains a more considerable proportion of fixed carbon—viz., 65T per
cent.
The
only pits in this wide area which are worked are at Warora, where the
out-turn was, in 1878, 1,500 tons per week. The great outlay by the
Government in connexion with the exploration and testing of the fieldf
has not yet been nearly repaid, the cost of extraction being heavy.
* Average of sixteen assays.
f £600,000 is stated to have been already expended at Warora alone at the time Mr. Hughes' report was printed.,
