logical surveys, both in the little known dis- 

 tricts of Canada, as well as in the densely popu- 

 lated and older provinces of the Dominion of 

 Canada. The volume opens with a ' Summary 

 Report of the Operations of the Geological 

 Survey for 1897,' by the Director. 



This report describes the various publications 

 issued during the year, the geological informa- 

 tion on the Yukon District, Bluseum and office 

 work, and also the result of boring operations in 

 Northern Alberta. The Director also gives re- 

 ports of explorations and surveys in British 

 Columbia, Manitoba, Ontario, Quebec, Hudson 

 Strait, New Brunswick and Nova Scotia. 

 It is followed by Mr. W. 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 Laurentiau, Couchich and Kee- 

 watin Steep Rock series, and Animikie series 

 of rock formations occurring in that district are 

 described and their contacts carefully noted. 

 The localities which are productive and of ec- 

 onomic 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 Nipis- 

 sing and Temiscaming Map-Sheets,' by Mr. A. 

 E. Barlow, forms Report I. of this volume, and 

 comprises 302 pages of text, including two ap- 

 pendixes : (1) ' List of Elevations ' ; (2) ' On 

 some Cambro-Silurian and Silurian Fossils 

 from the Lake Temiscaming, Lake Nipissing 

 and Mattawa Outliers,' by Henry BI. Ami, of 

 the paleontological staff. Mr. Barlow's report 

 forms a very complete study of an important 

 area of archsean rocks, in which he has de- 

 scribed the main geological features with a 

 great deal of pains, and gone into details of the 

 composition of the gneisses met in the Lauren- 

 Han of the area in question, together with their 

 petrograpbical relations ; also in the ' Grenville 

 series ' as developed and recognized by him in 

 that district. 



The Huronian system is then discussed, and 

 the breccia-conglomerates, the diabase and 

 gabbro and granites met with carefully de- 

 scribed, along with their relations to the post- 

 Archaean eruptives. He then devotes the suc- 

 ceeding chapters to a description of the Cam- 



bro-Silurian, Silurian and Pleistocene areas in- 

 cluded within the two maps of the district ex- 

 amined, and has a chapter on ' Economic Geol- 

 ogy ' describing the valuable deposits of gold, 

 silver, nickel, copper, iron and other minerals 

 occurring there. Regional de^'criptions 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 Sur- 

 face 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 Cbaudiere River region of Quebec. The 

 pleistocene marine shore-lines, the rivers and 

 lakes, the denudation that has taken place, to- 

 gether with the action and products of the Ap- 

 palachian glacier, the Laurentide ice, and that 

 of the local glaciers, as well as of floating ice, 

 are all discussed. The gold-bearing region is 

 then described. This includes the history of 

 mining in the Gilbert River, River du Loup, 

 Famine River, Mill River, Slate Creek, Main 

 Chaudiere Valley, Little Ditton River, etc. The 

 probable source of the alluvial gold is then given 

 by the author. 



' The Mineral Resources of New Bruns- 

 wick,' by Professor L. W. Bailey, forms Re- 

 port M of this volume and is a most welcome 

 report. This province ought to receive as well 

 as give more attention to the materials of eco- 

 nomic value, which occur in the earth's crust as 

 it is developed in that portion of the Dominion 

 of Canada by the sea. The geological forma- 

 tions, in which iron, copper, nickel, antimony, 

 lead, silver, manganese, coal, bituminous 

 shales, graphite, peat, gypsum,' granites, mar- 

 bles, dolomites, ornamental stones, infusorial 

 earths, mineral springs, and various other ma- 

 terials of economic value to man are to be 

 found, are described, and the mode of occur- 

 rence of these useful materials given, together 

 with their locations. A map of the minerals 

 of the province accompanies the report. 



Report S contains the customary and useful 

 report of the ' Section of Mineral Statistics and 

 Mines,' by Mr. E. D. Ingall. It contains up 

 wards of 200 pages of valuable notes on all the
