“ In the same level, seven hundred and fifty feet from the pit bottom, the coal 
measures three feet six inches, without any intervening shale. The same seam was 
worked in "Whitley’s shaft.” 
Mr. Hands conjectures that the seam worked in the Company’s mine may be the 
Lapham Seam. 
The How'ard, or Beaufort and Howard Seam, “ four feet five inches thick, with only 
a thin band of shale,” was worked from shafts fifty feet in depth. The seam “ lies 
probably above the seam worked by the Company” [Hands]. Mr. G-regory places the 
Beaufort Seam thirty feet above the Lapham. 
The Glenesk Seam has been worked from a shaft one hundred feet in depth. It is 
from eighteen inches to two feet in thickness.

Analyses Nos. 1, 2, and 3 are by Mr. Gregory ; Nos. i, 5, 0, and 7, by Mr. Bands ; and No. 8 by 
Dr. D. Marsh, quoted by Dr. J. R. M. Robertson in a Report on the Torbanelea Mine. 
On the coal-seams of the Burrum field generally, Mr. Hands remarks : — 
“ The analyses of the coals from the Burrum would show that, with reference to 
the volatile hydrocarbons, of which, of course, a high percentage is necessary for gas- 
making purposes, they are not quite as good as the Newcastle coals (New South Wales). 
Pourteen samples of the latter averaged 37'55 per cent, of volatile hydrocarbons, 
including water ; while the average of seven samples from Burrum is 31'5, that is also 
taking the hydrocarbons and w'ater together. 
“The ash, which represents so much of wmrse than useless matter, is by no means 
high ; the highest result being 8 per cent., and low'est 2T per cent., the average being 
4'6 per cent., as against an average of 4 97 per cent, in the Newcastle coal (New South 
Wales). It should be mentioned that the Burrum samples are from shallow depths, 
where the ash is generally higher. The ash is of a very light red or grey colour. 
“ The sulphur, averaging 0'4 per cent, in the three samples in which I determined 
it, is very low indeed, and the coal will compare favourably in that respect with coal 
from any part of the world. Unfortunately, however, in all the analyses of the 
Burrum coals hitherto made, the sulphur has not been determined. The percentage of 
this constituent is most important in coals used for gas-making. I’reedom from 
sulphur, too, is a great advantage in many metallurgical processes. 
“The cokes from the Queensland Collieries Company’s seam, the Lapham or 
Torbanlea seam, and the Burrum seam, are all good, coherent, dense cokes ; that from 
the first-named being the densest. The Burrum coal is not so good a steam coal on 
account of its tenderness, it being very easily broken up by attrition.”
