 of the whole, and clay more than a fifth ; others are building

2. Summary Report of the Geological Survey Department of 

 Canada, for the Calendar Year 190Jf. Robert Bell, Acting 

 Deputy Head and Director. Pp. xxxviii, 392, with seven geo- 

 logical maps. Ottawa, 1905. — This volume gives a concise 

 account of the work accomplished by the Canadian Survey dur- 

 ing 1904. The total number of parties engaged was twenty- 

 eight, and their labors extended over the entire area of the 

 country, extending not only from the Atlantic to the Pacific but 

 also into the Arctic. In general, the work carried on, as with 

 other surveys at the present time, was largely on the economic 

 side. As an illustration of what may be accomplished in this 

 way by careful geological work, the Director mentions the recent 

 discovery of a seam of coal, 10 feet thick, at a depth of 2,340 

 feet, near Pettigrew, in Cumberland County, Nova Scotia. The 

 bore-hole was sunk through an unproductive covering at the sug- 

 gestion of Mr. Hugh Fletcher of the Survey, as the result of his 

 knowledge of the minute structural geology of that district. 

 This successful result opens the prospect of finding numerous 

 coal seams through an area of fifty miles in length and thirty in 

 breadth. This discover} 7 is given as an illustration of the very 

 important economic results that follow accurate topographical 

 and geological work. 



Of the special reports given in the volume, two are devoted to 

 the Kluane and Duncan Creek mining districts, in Yukon Terri- 

 tory, others to the different coal-basins of British Columbia and 

 so on. An interesting account is also given by Commander A. P. 

 Low of the expedition to Hudson Bay and northward in 1903-4 

 by the S. S. Neptune. Among other points may be mentioned 

 a detailed statement of the phenomena accompanying the fall of 

 the meteorite at Shelburne, Ontario, on August 13, 1904. 



3. Glaciation of Southioestem New Zealand.— E. C. Andrews, 

 of the Department of Mines, Sydney, New South Wales, has 

 written on " Some interesting facts concerning the glaciation of 

 Southwestern New Zealand" (Trans. Austral. Assoc. Adv. Sci- 

 ence, 1904, 189-205, 8 plates), in which he sets forth with much 

 clearness the evidence of intense glacial erosion in the district of 

 the fiords about Milford sound. Hanging lateral valleys, par- 

 tially or totally truncated spurs, and the resulting rectilinear 

 cliffs or over-steepened valley sides, with lakes and over-deepened 

 fiords along the valley courses all occur in abundance. These 

 peculiar features are compared with those developed by normal 

 erosion in the highlands of northeastern Australia (" New Eng- 

 land "), and the conclusion is reached that as normal erosion can- 

 not possibly account for both, glacial erosion must be responsible 

 for the peculiar features that occur where glaciers are independ- 

 ently shown to have existed. In a supplementary note, Andrews
