economic deposits have yet been discovered and on the whole con- 
ditions for the formation of ore deposits have not been as favorable as 
in nearby areas. 
3. The pre-Cambrian rocks of this area are divided into an igneous 
complex consisting of altered volcanic and intrusive rocks, a sedimentary 
complex of granite-gneiss and staurolite-schist, and batholithic intru- 
sives. Ordovician dolomites occur and Pleistocene and Recent deposits 
are abundant. fs 
4. The geology of this area is very similiar to that of the Reed-File 
lakes area. A number of productive gold-bearing quartz veins occur 
near the borders of the granite masses. 
5. Because of the practical exhaustion of homestead prairie land in 
easily accessible areas, a map of an area of about 1,500 sq. mi. around 
Lake Winnipegosis was prepared. This map will show the character 
of the soil and forests and will also indicate the land that can be readily 
cleared. 
6. The gold-quartz veins in the pre-Cambrian rocks of southeastern 
Manitoba were sampled and assayed for both gold and platinum. Most 
of the assays showed a very small amount of gold present but in no case 
was platinum detected. In a fine-grained, massive, roughly sheeted, 
hornblendic rock scheelite occurs in small vuggy lenses not in all cases 
parallel to the sheeting. The returns from a shipment of the ore to 
the Ore Dressing Laboratory, Ottawa, were not encouraging.

2. The drift over the Carboniferous rocks of the Sydney coal basin 
contains bowlders of rocks which outcrop to the south of the basin and 
this with the general direction of glacial striae proves that the direction 
of ice movement in this part of Cape Breton Island was northward. 
This report is almost entirely economic and gives many details concern- 
ing the structure and extent of a number of coal horizons. The New
