THE COLLIE COAL.
TO THE EDITOR.
SIR, — In the leading article of your valuable paper you, this morning,
refer to assays I have made of the Collie coal (permit me, in parenthesis,
to remark that I am not the Government Geologist), and you compare the one
I made last November (published in the WEST AUSTRALIAN of 23rd November,
1889) with that recently made by Mr Smith, of the Royal School of Mines,
but overlook the later one given in my letter to you of the 21st April and
published by you on the following day, and which was still more
favourable, for the coal came from a greater depth than had been reached
when the sample was sent to London, and contained less water (10.87
against 12.75) and more fixed carbon (52.87 against 49.50), while I found
2.56 percent of ash and Mr Smith 2.80.
These figures are of interest as showing the steady improvement of the coal in depth.
I am, &c.,
BERNARD H. WOODWARD, F.G.S.,
Assayer.
Perth, May 21.
