L’Ange and Limestone Mountain, with a view to correlate 
the rocks of the two sides. 
His topographical and geological surveys in the country 
directly north of Lake Huron embraced a greater or less 
portion of the course of each of the following rivers: Echo, 
Garden, Thessalon, Mississagi, Serpent, Blind, Spanish, 
Whitefish, Wahnapite, Sturgeon and Maskinongé; also 
Lake Wahnapite and numerous lakes connected with the 
Thessalon, Mississagi, Blind and Maskinongé Rivers. Be- 
tween Georgian Bay and the Ottawa, he surveyed most of 
the numerous channels of the French River, the Sturgeon, 
Meganatawan, Muskoka, Petewawé, Bonnechere, south- 
west branch of the Madawaska, and the head waters of the 
Ottonabee Rivers and many lakes connected with them, 
including Lake Nipissing and Muskoka Lake. In Lower 
Canada he surveyed the Bonaventure, St. John or Douglas- 
town, Matane and Ste. Anne des Monts, and assisted Logan 
(in 1844) to measure a traverse from the St. Lawrence to 
Baie de Chaleur by way of the Chatte and Cascapedia 
Rivers. During the season of 1849 he was again with 
Logan in making a geological survey of the region between 
the Chaudiére River and the Temiscouata Road. 
The early finding of nickel ore on the north shore of 
Lake Huron is worth referring to in connection with Mr. 
Murray’s work and the subsequent discoveries of this metal 
in such abundance in the Sudbury District. In 1848 Murray 
examined the Wallace Mine, near the mouth of Whitefish 
River, where the initial discovery was made and which 
had been opened the previous year. The ore which he 
brought to the laboratory of the Survey at that time was 
found to contain 8°26 per cent. of nickel, “ but as two fifths 
of the specimen consisted of earthy materials which might 
readily be separated by dressing, the quantity of nickel in 
the pure ore which this would represent, would equal 
nearly 14 per cent.” The country rocks of the Wallace 
Mine belong to the same part of the Huronian system as 
those in the vicinity of Sudbury Junction, which lies on 
their general strike to the north-eastward.
