economic importance are found only in the Kootenay, and a large 
reserve of bituminous coal occurs within the Rocky Mountains. 
4. This is a description of the apparatus and the results of a number 
of experiments carried on at various gas wells. At the pressures under 
which the tests were made the amount of gasoline in the Alberta gases 
per 1,000 cu. ft. varied from o.1 pints to 3.7 pints. 
5. This area is covered with glacial drift, averaging from 4o to 70 
ft. in thickness. ‘Two main terminal moraines cross the area but ground 
moraine covers most of the area. The residual alkali material formed 
in the dried-up sloughs contains only a very small per cent of potash, 
and is of no economic importance. The waters from the drift are 
hard and contain calcium and magnesium carbonates and sulphates 
while the waters from wells reaching the Tertiary strata are soft and 
contain considerable sodium chloride.

1. Chalcopyrite was discovered along joint or fracture zones in 
fine-grained, massive greenstone. Some distance from these occurrences 
the greenstone is intruded by granite and these deposits are directly 
related to these intrusions. With the present conditions of transporta- 
tion mining conditions are not favorable for this area. 
2. The geology of this area is much simpler than that of other 
nearby areas in northern Manitoba as the pre-Cambrian is represented 
by the Amisk series of greenstones and derived schists, and intrusive 
granites. The younger pre-Cambrian formations are absent, and since 
the crest of a large anticline crosses this area these younger formations 
have probably been removed by erosion from the crest of this anticline. 
Ordovician dolomites and Glacial and Recent deposits are noted. No
