202 Canadian, Record of Science. 



This report describes the various publications issued during the 

 year, the geological information on the Yukon District, Museum and 

 ofl&ce work, and also the result of boring operations in Northern 

 Allierta. The Director also gives reports of explorations and surveys 

 in British Columbia, Manitoba, Ontario, Quebec, Hudson Strait, New 

 Brunswick and Nova Scotia. It is followed by Mr. Mclnnes's report 

 " On the Geology of the Area covered by the Seine River and Lake 

 Shebandowan Map-Sheets," in the gold-bearing series of Northern 

 Ontario. The Laurentian, Couchich and Keewatin Steep Rock series, 

 and Animikie series of rock formations occurring in that district are 

 described and their contents carefully noted. The localities which are 

 productive and of economic value receive special attention and notes 

 on the glacial geology are also included. This forms Report II. of the 

 volume. 



" Report on the Area included by the Nipissing and Temiscaming 

 Map-Sheets," by Mr. A. E. Barlow, forms Report I. of this volume, 

 and comprises 302 pages of text, including two appendices : (1) " List 

 of Elevations"; (2) "On some Cambro-Silurian and Silurian Fossils 

 from the Lake Temiscaming, Lake Nipissing and Mattawa Outliers," 

 by Henry M. Ami, of the pateontological staff. Mr. Barlow's report 

 forms a very complete study of an important area of archtean rocks, in 

 which he has described the main geological features with a great deal 

 of pains, and gone into details of the composition of tlie gneisses met 

 in the Laurentian of the ai-ea in question, together with their petro- 

 graphical relations ; also in the " Grenville series " as developed and 

 recognized by him in that district. 



The Huronian system is then discussed, and the breccia-conglo- 

 merates, the diabase and gabbro and granites met with carefullj* 

 described, along with their relations to the post- .4rchsean eruptives. 

 He then devotes the succeeding chapters to a description of the 

 Cambro-Silurian, Silurian and Pleistocene areas included within the 

 two maps of the district examined, and has a chapter on " Economic 

 Geology " describing the valuable deposits of gold, silver, nickel, 

 copper, iron and other minerals occurring there. Regional descrip- 

 tions follow, which will prove of great value to prospectors and miners 

 in a district, full of beautiful lakes and waterfalls and magnificent 

 scenery, and holding economic minerals of untold wealth. 



Report J, by Mr. R. Chalmers, " On the Surface Geology and 

 Auriferous Deposits of South-eastern Quebec," contains upwards of 

 160 pages of very valuable reading and illustrations, with statistics of 

 the gold production of the Beauce and Chaudiere River region of 

 Quebec. The pleistocene marine shore-lines, the rivers and lakes, 

 the denudation that has taken place, together with the action and 

 products of the Appalachian glacier, the Laurentide ice, and tliat of 

 the local glaciers, as well as of floating ice, are all discussed. The
