FORESTRY. 



Modern forestry, A. Kuuei-ka (Modcrnc Forstwirtsdiaft. Vienna and Leip- 

 zig: Franz Dcuticke, 1918, pp. X-\-190, pi. 1). — A treatise on the selection system 

 of forest management, based primarily on the author's successful experience 

 on various private forests in carrying out the principles advocated by Wagner 

 (E. S. R., 20, p. 645). A modirtcation of Wagner's method of regeneration is 

 advocated, in that tlie author recommends felling-strips 30 to 50 meters broad 

 in coulisse-form arrangement, with a limited number of regeneration cuttings, 

 W'hereas Wagner advocates the use of narrow border strips with many regen- 

 eration cuttings. 



The subject matter is discussed under the following general headings : Prin- 

 ciples of modern forest management ; preparations for the installation of a 

 natural working system with special reference to the selection-strip system ; 

 growing the most important timber species in the holes and gaps of the selec- 

 tion strips ; and the application of the selection-strip system in modern for- 

 estry.

A forest policy for Louisiana, R. D. Forbes {Jour. Forestry, 17 {1919), No. 5, 

 pp. 503-5 L'l ) .—As a result of 14 months' study of Louisiana conditions, the

 value for agriculture, live-stock production, and forest growth, and presents 

 the broader phases of what he considers the proper state forest policy to be 

 carried out by the State forester, working under the Commissioner of Con- 

 servation. 



How can the private forest lands be brought under forest management? 

 W. N. Sparhawk {Jour. Forestry, 17 {1919), No. 5, pp. 490-496) .—The author 

 critically reviews plans already advocated for bringing about the practice of 

 forestry on private lands, and presents a plan by which it is believed that 

 • the practice of forestiy on lands now in private ownership may be made en- 

 tirely practicable. This plan is essentially a leasing system, which provides 

 for the retention of jirivate ownership with public operation.
