740 EXPERIMENT STATION RECORD. 



Indian state forestry, S. Eardlky-AVilmot (Jour. Roy. Soc. Arts, 5S {tdlO), 

 i\'o, .iOUS, PI). 'ilJJ-,J(iS). — This paper, to,i;etlier with the accompanyiuf;; discussion, 

 deals with forest conditions in India and the progress made in forest manage- 

 ment. 



Reports on certain continental forests, F. L. Cowley-Brown {Madras: 

 Gort., 190S, pp. <SJ, figs. 20). — This report (>mbraces the salient features of an 

 inspection tour of a number of continental forests. 



In part 1 consideration is given to the forests of the Gironde and Landes 

 coasts, with special reference to the fixation of the dunes and moving sands, 

 forest management, and resin exploitation. Succeeding parts of the report take 

 up the forest of Heppenheim, forests in the Pau conservation, projects of defense 

 in the Pyrenees and in the Alps, the forest school at Vallombrosa, forests 

 in the Nice conservation, the instruction forest and forest school at Nancy, 

 together with several supplementary notes on French forests. Suggestions are 

 also included relative to the application of the observations reported to condi- 

 tions in India. 



Forest divisions in Burma and the United Provinces, F. A. Leete (Indian 

 Forester, 36 (1010), ^o. 1-2, pp. .'il-(j'.)). — A descriptive account of these di- 

 visions is given, including information relative to their management. 



The structure, properties, and uses of wood, H. Wilda (Das Hoi:; Aiifbau, 

 Eigensvhapen itnd Vericendung. Leipsiv, 1909, pp. 125, figs. 33). — A concise 

 treatise on this subject, discussing the growth and structure of woods, their 

 physical properties, enemies and i)rotection, the uses of wood in various trades 

 and industries, including information relative to the chemical and mechanical 

 treatment and the adaptation of various kinds of wood for industrial purposes. 



The preservative treatment of farm timbers, ('. P. Willis ( U. 8. Dcpt. 

 Agr., Farmers' Bui. 387, pp. 19, figs. 5). — The information presented is based 

 upon preservative studies conducted by the Forest Service in cooperation with 

 the Commissioner of Agriculture and Industries of Alabama, and the Alabama, 

 Iowa, Louisiana, Maryland, Minnesota, and South Carolina stations. The 

 methods of prolonging the life of fence posts were found to be in the follow- 

 ing order of efflciency, beginning with the cheapest and less effective: Peeling 

 and seaoning, charring, painting, dipping, the cold bath treatment, and impreg- 

 nation with creosote. 



In the experimental work conducted, impregnation with creosote was found to 

 be decidedly the best preservative treatment. The use of creosote is discussed, 

 relative to method of treatment, forms of treating tanks, preparation of posts 

 for treatment, the application of preservative, and the cost and value of treat- 

 ment. It is pointed out that all ordinary farm lumber may be treated in a 

 very similar manner to posts. Sjiecial consideration is given to the treatment 

 of shingles, creosote and other derivatives of coal tar being deemed the best anti- 

 septics. In order to overcome the odors which these substances possess, it is 

 advised that the shingles be seasoned for a few weeks between treating and 

 laying. 



Preservatives for wood paving blocks, C. N. Forrest (Engin. Rcc, 61 

 (1910), Xo. 16, pp. 531, 532). — The author presents data to show that tar is a 

 better water-proofing agent than creosote and will remain in the blocks for a 

 longer period of time. Tar is also being adopted in lieu of creosote oil for 

 wood paving blocks because it is a cheaper preservative. 



Rubber, A. Fayol (Le Caoutchouc. Paris, 1909, pp. III+13S). — A technical 

 treatise on latex and the preparation and manufacture of rubber, including 

 introductory remarks relative to the history of the rubber industry. 



[Rubber analyses] (Bui. Imp. Inst. [So. Kensington], 7 (1909), Ao. 3, pp. 

 255-263). — Analj'ses are reported of samples of Funtumia clastica, Clitandra
