The Woodman's Handbook. By H. S. Graves and E. A. 

 Ziegler. Bulletin 36, U. S. Forest Service. (Revised and en- 

 larged.) Washington, D. C. 1910. Pp. 208. 



This new edition contains the Scribner, Doyle, Maine and 

 Spaulding log rules complete and a table giving a comparison of 

 44 log rules for the contents of 16- foot logs. Standard and cubic 

 measures are discussed and cord measure, with their equivalents. 

 Thirty pages are devoted to timber estimating, and the better 

 methods of estimating, with the principles underlying them, are 

 thoroughly covered. Growth is briefly discussed. The more use-

 measures, calipers, are described. The most important addition

 yellow poplar. The small number of these yield tables available 

 for publication shows the need for investigations along this 

 line. H. H. C.

 States have pointed to the vast untouched timber resources of
