liifj^her above the lake level." Tt is believer! that the rocks over- 

 lying the Shushwap Series are in all probability Palaeozoic in age, 

 and may eventually be referred to various systems, including the 

 Carboniferous, and extending downward to the Lower Cambrian. 



Dr. Dawson's report is accompanied by a " reconnaissance " map 

 (coloured geologically) on a scale of four miles to the inch, and is 

 also illusti'ated by two views of Kootanie Lake. 



Mr. R. G. McConnell, assistant to Dr. Dawson, gives the results 

 in Report D. (pp. 1 D to 163 D) of an exploration in the Yukon and 

 Mackenzie Basins, North West Territory. The Survey was carried 

 out under Dr. Dawson's direction, and in connection with the Yukon 

 Exploring Expedition. It occupied parts of the seasons of 1887- 

 1888. In a " Geological Summary " the occurrence of Archajan 

 rocks is noted east of the Rocky Mountains, on the Slave River, and 

 at Fort Rae, while unfossiliferous dolomites, limestone, and calc- 

 schists, supposed to be of Cambro-Silurian, or later Cambrian age, 

 were met with along the Liard River, west of the Rocky Mountains. 

 Upper Devonian rocks containing many characteristic fossils were 

 observed on the Hay and Mackenzie Rivers, and Triassic rocks and 

 fossils on the Liard River. Cretaceous I'ocks were recognized east 

 of the foot-hills, containing fossils similar to "Series C." of the 

 Queen Charlotte Islands ; among them were Plncenticeras Pere- 

 zianum, Camptonectes, and Inoceramus. Tertiary beds, resting un- 

 conformably on the underlying Cretaceous shales and Devonian 

 limestones, were seen at the mouth of Bear River. Remains of 

 plants, described or determined by Sir William Dawson, were 

 abundant in some of the beds. The age of these Tertiary beds is 

 judged, on stratigraphical, as well as lithological evidence, to be 

 Miocene, though Sir William Dawson refers them, on the plant 

 evidence, to the Laramie. A chapter on " Superficial Deposits and 

 Glacial Action," and a synopsis of the economic minerals of the 

 region, which include Gold, Silver, Copper, Salt, Petroleum, etc., 

 concludes the geological portion of this report ; the remainder is 

 taken up with a minute description of the physical features of the 

 routes followed by the surveying party. The report succeeding Mr. 

 McConnell's in the series is on the Exploration of the Glacial Lake 

 Agassiz in Manitoba, by Mr. Warren Upham (pp. 1 E. to 156 E.) ; 

 but it has already been reviewed in its separate issue in this 

 Magazine (May, 1891, p. 228). Dr. R. W. Ells presents a report 

 (pp. 1 K. to 159 K.) on the Mineral Resources of the Province of 

 Quebec, in which he describes the metals and their ores (Gold, 

 Silver, Copper) and the various minerals used for heating and 

 lighting (Coal, Peat, Petroleum) ; chemical manufactures (Apatite, 

 Chromic Iron, Manganese), materials used in construction (Marbles, 

 etc.), and the refractory materials, which include Graphite, Asbestos, 

 and Soapstone. Mr. Robert Chalmers reports upon the Surface 

 Geology of Southern New Brunswick (pp. 1 N. to 92 N.), and records 

 the results of careful investigations, in the cleared and settled parts 

 of the country, in regard to glacial strife, Boulder-clay, stratified 

 deposits, alluvium, the agricultural character of the soil, forests, etc.
