"To sum up, then, only a mere fraction of one per cent, of 

 the area we surveyed now carries merchantable timber. There 

 is probably enough timber available to build the rough construc- 

 tion work of the Hudson Bay Railway." 



The territory inspected was some 8,000 square miles. The 

 total timber found was 361,300 ties and 9,424,000 feet of lumber, 

 and one-half of this is believed to be commercially inaccessible 

 to the railway. J, H. W. 



Uses of Commercial Woods of the United States-' I. Cedars, 

 Cypresses and Sequoias. By W. L. Hall and Hu Maxwell. Bul- 

 letin 95, U. S. Forest Service. Washington, D. C. 191 1. 

 Pp. 62. 



This is the first of a series of bulletins in which it is planned 

 to bring together the available information on the uses of the 

 different commercial woods. 



Each species is considered separately. The physical properties 

 are first given, namely, weight, specific gravity, ash, fuel value, 

 modulus of rupture, modulus of elasticity, and character and 

 qualities of the wood. This is followed by a discussion of the 

 commercial range and supply, uses, manufacture and products, 

 by-products, etc. Each topic is elaborated in great detail, the 

 treatment resulting in what one might term the historical tech- 

 nology. The bulletin is accordingly replete with information 

 gathered from very many and widely scattered sources, covering 

 the period from the earliest settlement of the country to the 

 present. . It forms most interesting reading. 



The present issue deals with the species of Thuja, Chamae- 

 cyparis, Juniperus, Libocedrus, Taxodium and Sequoia.
