 LL.D., F.R.S. Annual Report, Volume XIII : Reports A, D, DD, 

 P and FF, K, L, M and MM, R, S. 1900. 8vo ; pp. 747, xvii, 

 15 plates, figures, and 8 maps. (Ottawa : S. E. Dawson, 1903.) 



THIS volume is in the usual form of a number of independent 

 reports, each distinguished by a letter and separately paged, 

 which have been issued previously as completed. It is presumed 

 to refer to the operations of the Survey to the end of the year 1900, 

 but some of the reports are based on observations not made till 1901. 



The first Report (A), extending to 203 pages, contains a general 

 summary of the Survey work for 1900. It was drawn up and 

 submitted by the late Director of the Survej^ Dr. G. M. Dawson, in 

 January, 1901, and was probably his last piece of official work, for 

 his death took place in the March following. 



Beginning in the extreme north-west of the Dominion, mention is 

 first made of the exploration by Mr. R. G. McConnell of the valley 

 of the Stewart River and of a part of the Yukon, of which it is 

 a tributary. The country bordering the rivers is mountainous ; the 

 rocks are of granite, granite-gneiss, quartz and hornblende schists, 

 and crystalline limestones, overlain by dark siliceous slates. On 

 the Klondike River there are outcrops of soft shales and sandstones 

 with beds of lignite, which is mined for heating purposes. These 

 beds are probably of Tertiary age. 



In British Columbia, the further investigations of Mr. J. C. 

 Gwillim, in the mountainous district between the Atlin and Teslin 

 lakes, show that the rocks are mainly of quartzite, limestone, and 

 greenstone, whilst at lower levels there is a great thickness of 

 sandstone, apparently Cretaceous in age. In the Districts of East 

 and West Kootenay, work was carried on by Mr. R. W. Brock and 

 Mr. J. McEvoy, and a report of the Crow's Nest Coalfield, west of 

 the summit of the Rocky Mountains, shows that in this district 

 limestones containing Productus are succeeded by Cretaceous con- 

 glomerates, shales, and sandstones, with beds of coal, in an 

 apparently continuous section 5,000 feet in thickness. 



In the Mackenzie District, at the far north, Mr. J. M. Bell 

 explored the regions between the Great Slave and the Great Bear 

 Lakes, following the Mackenzie and Bear Rivers, and notes the 

 presence of Archgean, Palaeozoic, Cretaceous, and Tertiary rocks. 

 Round the Great Bear Lake there are wonderful examples of old 

 shore-lines indicating the former extent of the lake. In some 

 places on the north-west side they are over 300 feet in height and 

 3-4 miles back from the present shore. Near the shore itself there 

 are also broad beaches and terraces of pebbles from 10 to 100 feet in 

 height. 



In the Province of Ontario, Mr. Mclnnes reports on the areas 

 round Port Arthur to the international boundary, and Dr. R. Bell 

 (the present Director) gives the results of his survey of the
