ful. He had himself washed gold there found on the surface, 

 and he never saw any place so rich in auriferous ore as that 

 region. He estimated its produce at $ioo a ton, whilst Prof 

 Chapman had estimated it at $50 or $60 a ton from his own 

 examination. By the present system 90 per cent of the gold 

 was lost, every little particle of gold being covered with a film 

 of arsenic so that the quicksilver would not touch it. If Mr. 

 Dobson's invention succeeds in cleansing the particles of gold 

 from the arsenic, it would be worth millions of dollars to the 

 country. He was glad that there were several barrels of ore 

 in Toronto ready to be tested by this machine. He next 

 referred to the great extent of the gold sands of Canada, and 

 the wealth of the deposits south of Quebec. There was no 

 river which came down from the Laurentian formation that 

 did not carry gold. Referring to his own experience, he had 

 washed gold in the Parry Sound district, at Port Arthur, Pearl 

 River, and other places. He had seen millions of tons of the 

 black sand that produced gold back in Haliburton. Canada 

 has riches beyond belief, and the country was anxiously look- 

 ing for some scientific process by which this immense wealth 

 would be made available.
