tention to the theoretical and scientific sides of the subject, but 

 his sympathies are unquestionably on the side of the simplest and 

 most practical methods. One finds, therefore, together with a 

 very full account of nearly all the most interesting methods of 

 cubing, also a description of many "shortcuts" to rapid determi- 

 nation of the volume of felled and standing trees, so useful to the 

 practitioner, who will not fail to appreciate such a feature. 



The methods in vogue in France for determining the volume 

 of stands by means of special graphically constructed volume 

 tables are, for the first time, fully and clearly described. 



Under the Factors of Forest Production is, as usual, discussed 

 the importance of nature, labor, and capital in the production of 

 wood crops, the author fully sharing the accepted views on this 

 subject. 



Forest Valuation, in spite of the intricate character of the sub-

 with illustrations, the structure not only of the indigenous but a 

 large number of exotic species, including many of our own. The 

 curious statement is made that the sap of the yellow pines always 

 blues when used. Sixtypagesaredevoted to a discussion of proper- 

 ties of wood. Over 100 pages treat of diseases and are especial- 

 ly well illustrated with colored plates. Preservative processes 

 are discussed on 48 pages, and several processes not in general 

 use are described. The balance of 225 pages discusses logging 

 methods, fully illustrated, in nine chapters, the bulk being of 

 course devoted to methods of transportation. While many of the
