EIGHTEENTH ORDINARY MEETING. 269 
Heat is applied beneath the shovel to drive off the quicksilver that 
could not be removed by pressure. After a sufficient application of 
heat, the button of amalgam assumes a gold colour and is allowed to 
cool. This is the gold amalgam of commerce. 
The rest of the paper was descriptive of the machine methods of 
recovering the gold. 
In answer to questions from Messrs. Murray, Miles, Bain, 
Livingston and others, Mr. Levey said that hand-work had 
been going on for nine years, and machinery work five years ; 
the first was not commonly satisfactory, and the other pro- 
duced about $6 per day ; that the tract was 200 miles north 
of Calgary, and extended 50 miles; that the yield per pan 
was about two cents; that the sand contained magnetic iron 
and a little platinum ; that there were from 1,500 tu 2,000 
settlers ; that there were large boulders of gneiss and granite 
which, he thought, came from the Laurentian to the north- 
east; and he thought hydraulic mining would pay after a 
very large expenditure.
