568 Reviews — Geological Survey of Canada. 



Mr. D. B. DowHng continued his examination of the coalfields of 

 the Rocky Mountain region adjacent to the line of the Canadian 

 Pacific Railway, where he has made important discoveries of coal- 

 seams. This report is accompanied by a coloured geological map 

 of the Costigan Coalfield, Alberta, and other illustrations. 



During the Canadian Government expedition to " Hudson Bay and 

 Northward " under Mr. A. P. Low, some observations were made 

 as time would allow (the object of the expedition being other than 

 scientific) upon the geology and natural history of the coast and 

 adjacent regions. The scientific results of this expedition indicate 

 the importance of the presence of trained scientific men on such 

 expeditions, if full advantage of them is to be taken. The western 

 coast of Hudson Bay was geologically examined from the head of 

 Chesterfield Inlet to that of Wagei", and track surveys made. The 

 western shore of Southampton Island and Ungava Bay were 

 similarly examined, a survey of 2,041 miles being in all accom- 

 plished. The predominant rocks observed on Southampton Island 

 were a coarse granite-gneiss with broken bands of diabase and 

 chloritic schists. These rocks are overlain by Silurian limestone 

 in places. On the eastern shore of Ungava Bay the rocks are 

 all Archaean, principally granite-gneiss, with a large amount of 

 basic irruptives, such as gabbro and anorthosite. Large collections 

 of rocks, fossils, the northern mammals and birds, as well as fishes 

 and marine invertebrates, were made, as also Arctic plants. The 

 expedition occupied 14 months from the time of leaving Halifax to 

 its return to that port. 



Mr. Charles Camsell made geological and the necessary topo- 

 graphical surveys in Eastern Manitoba and those parts of the 

 country between Lake Winnipeg and the Severn Rivex*. This area 

 is occupied by rocks of Archaean age, principally granites and 

 gneisses. Mr. Camsell traced the boundaries of the eastern ex- 

 tension of the Huronian area around Red Lake, and also discovered 

 some additional small areas of Huronian rocks. 



Mr. Wm. Mclnnes followed up his interesting explorations of the 

 previous year in the extensive and hitherto almost unknown region 

 of the Winisk River and surrounding country, lying to the south of 

 Hudson Bay proper. His work adds materially to a knowledge of 

 the rock-formations of this region. 



Mr. W. J. Wilson worked in the country lying northward of 

 Long Lake, north of the central part of Lake Superior, including 

 the head-waters of some large branches of the Albany River. He 

 traced out a further extension of a known area of Huronian rocks 

 in which gold, copper, and iron ores may eventually be found. 



Mr. Owen O'Sullivan surveyed and explored the southern and 

 western coasts of James Bay as far north as Cape Henrietta Maria. 

 These coasts, occupying the central part of the map of Canada, had not 

 previously been very accurately delineated. The work was under- 

 taken to supply this want, and at the same time to observe and 

 record the geological features of this region. A map of the coastline 

 surveyed is added to the report.
