264 MAGNETIC IRON ORES OF VICTORIA COUNTY. 
at the Paxton mine in Lutterworth, or a closer grained magnetite 
carrying a certain amount of pyrites, as is seen in the Snowdon occur- 
rences, to a compact crystalline ore containing more or less titanium, 
such as is found at Pine Lake and other places. 
Tn all cases the analyses of the picked specimens were practically 
the same, about 60 % metallic iron, and practically free from phos- 
phorus, sulphur and titanium. 
The average samples of ores from the Snowdon properties, which 
would represent the character of the Victoria, Miles, Ledyard and, 
Howland, is the following : 1

These would require thorough calcining to remove the sulphur. 
At the Howland mine it was calcined very roughly in large pieces in 
heaps of 100 tons, but as samples of the calcined ore which I obtained 
shewed the same amount of sulphur as the raw ore, the present sys- 
tem of calcining is practically useless.

This ore has the decided advantage of being so free from sulphur 
that it would not require calcining. 
The third class of samples I collected and mentioned as taken from 
the dump, shewed that waste ore contained over 30 % metallic iron.
