THE COLLIE RIVER COAL.
TO THE EDITOR.
The following highly satisfactory report of an analysis mande by Mr. B. H.
Woodward has been forwarded to the Government, in connection with some
samples of coal sent to the authorities by Mr. D. A. Hay of Bunbury: —
Composition per cent.
{Water ... 15.20
Volatile matter, 49.89 {Gases, &c ... 32.46
{Sulphur ... 2.23
{Fixed Carbon 45.03
Coke, 50.11 {Ash... ... 5.08

100.00 100.00
The above was from the bottom of the river specimen from depth of 17 feet.
{Water ... 10.87
Volatile matter, 44.87 {Gases, &c ... 31.47
{Sulphur ... 2.23
{Fixed Carbon 52.87
Coke, 55.43 {Ash... ... 2.56
------ ------
100.00 100.00
Calorific value (theoretical) 11; the practical will be about 9.5. It
does not cake, but leaves the coke in powder, so will not do for the
manufacture of illuminating gas, but will be valuable for steam boilers,
household purposes, &c.
