preparation for itlaiitiug. planting the trees, care of plantations after planting, 

 distances between trees, pruning, thinning, the use of willow and poplar cuttings, 

 gaps in plantations, transplanting, and grading up poplar bluffs.

Tree planting on the prairies of Manitoba, Saskatchewan, and Alberta, 

 N. M. Ross (Dept. Int. Canada, Forestry Braivch Bui. J, 1910, pp. lOJf, pis. 3Ji, 

 figs. 2). — This bulletin has been prepared with the idea of furnishing practical 

 information to the settler on the western prairies as to the best methods of 

 propagating, planting, and managing hai'dy trees for shelter belts, windbreaks, 

 and plantations. The information is based upon the successful results of 

 planting and general nursery work. Only such trees as have been provetl 

 absolutely hardy are recommended for planting. 



Part 1 discusses the natural conditions and the benefits to be derived from 

 tree planting on the prairies, and gives directions for establishing plantations. 

 Part 2 contains information relative to the character, uses, cultural require- 

 ments, and methods of propagating the various deciduous and coniferous trees 

 recommended. 



Our timber wealth and its conservation, W. J. Sutton (Bui. Nat- Hist. Soc.

The Olympic National Forest: Its resources and their management, 

 F. Burns {U. S. Dept. Agr., Forest Serv. Bui. 89, pp. 20, pis. 3).— This bulletin 

 contains an account of the Olympic National Forest in the State of Washing- 

 ton I'elative to its resources, topography and drainage, land classification, water 

 and agriculture, water power, timber, burns, grazing, mining, settlement, and 

 permanent improvements. 



The merchantable stand within this forest approximates 25,500,000,000 ft. 

 b. m. It was established to provide a permanent supply which could be drawn 

 upon when the immense stands now upon private holdings have been cut aw^ay. 

 It is estimated that the forest is capable of producing a sustained annual yield 

 of 250,000,000 ft. b. m. 



Forest products of Canada, 1909. — Pulp wood, H. R. MacMillan (Dept. 

 Int. Canada, Forestry Branch Bui. 12, 1910, pp. 9). — The pulp wood consump- 

 tion in Canada is shown by species. Provinces, and processes. There were pro- 

 duced in Canada in 1909, 1,537,762 cords of pulp wood, valued at $9,216,739;

Forest products of Canada, 1909. — Poles purchased, H. R. MacMillan 

 (Dept. Int. Canada, Forestry Branch Bui. 13, 1911, pp. 7). — A statistical re- 

 view based upon data received from the telegraph, telephone, electric light and 

 power companies, and the electric and steam railroads operating in Canada. 

 The number, total cost, and average cost are given by species, chief uses, and 

 length classes, including comparative data for 1908. The prices of cedar poles 

 in the United States and Canada in 1908 are also compared. 



The total number of poles purchased in Canada in 1909 was 358,255, or 92.9 

 per cent more than in 1908. Cedar is the wood most frequently used, since it 

 is cheap, easily handled, and durable. 



Forest products of Canada, 1909. — Cross-ties purchased, H. R. MacMillan 

 (Dept. Int. Canada, Forestry Branch Bui. 14, 1911, pp. 8). — A statistical re-
