The Memorial issued by the Commercial Clubs of St. Paul and 

 Minneapolis, Minnesota, in behalf of the maintenance of the 

 Minnesota National forest reserve gives a history of this legisla- 

 tion from its inception and a resume of results obtained since the 

 work was commenced in 1903 by the U. S. Forest Service. This 

 reserve was created by act of Congress and provided for a system- 

 atic attempt at cutting White and Norway Pine under methods 

 which would insure natural re-stocking of the area. 



As bearing upon the success of the work and the difftculties 

 and opposition it has had to ' encounter, the memorial is well 

 worth the notice of foresters. H. H. C. 



Le Bois, par Jean Beauverie, avec une preface de M. Daubree.

This is a most exhaustive and practically the only French 

 work on forest technology. It consists of two volumes, contain- 

 ing over 1400 pages, 480 drawings, and an introduction by 

 Daubree, the director of forests in France. Of the thirteen 

 chapters the first two are devoted to the anatomical structure of 

 wood and its chemical composition (100 pages), and one chapter 

 to each of the following subjects : physical properties of wood 

 (80 p.); conditions of tree and forest growth (25 p.); methods 

 and machinery employed in the utilization of the forest (25 p.); 

 timber estimating and timber trade (50 p.); defects and injuries 

 of wood (285 p.); durability of wood and lengthening of its life 

 (130 p.); native and foreign species important in commerce 

 (300 p.); cork tissue and cork industry (sop.); production of 

 wood in the world (100 p.); forest trees growing in the French 

 colonies (130 p.); grading of timber and of the chemical products 

 of wood (35 p.). 



The work is full of valuable information and must be classed 

 with standard works on the subject. The only drawback in our 

 opinion is that the material has not been arranged according to a 

 well thought-out plan and is not well balanced. Thus while the 

 chapter on injuries to timber is spread over more than 300 pages 

 and includes a great deal of unnecessary detail on insects, to such 

 an important subject as the present methods of grading is given 

 but 35 pages. R. Z.
