246 NOTES ON A CAPE BRETON MINERAL AND 
The absence of iron and the comparatively large amount of 
Manganese in the composition of this mineral would class it as 
more nearly allied to Hiibnerite than to Wolframite. 
In the same paper reference is made to the beneficial effects 
from washing certain Cape Breton coals, whereby the quantity 
of Sulphur ordinarily contained in coal as supplied from the 
slack heaps is greatly reduced, and the resulting Coke is made 
suitable for Iron smelting. The experience at the Ferrona fur- 
nace is spoken of, but as the reference to the operations at that 
furnace are somewhat incomplete, the following data supplied 
by the Manager, Mr. J. D. Fraser, will doubtless on comparison 
prove of interest. A test made in September and October, 1895, 
with fifty-ton samples from each of the following Mines, gave 
as follows :—

A test of 10,000 tons of small coal in December, 1897, and 
January, 1898, received from the Dominion Coal Company, 
gave the following average results :—
