together with suggestions relative to needed legislation and the text of a sug- 

 gested forest law. 



Porest products of Canada, 1909, H. R. MacMillan (Dept. Int. Canada, 

 Forestry Branch Bui. 11, ID 10, irp. 30, clgms. 2). — This bulletin comprises statis- 

 tics on the production of lumber, square timber, lath, and shingles in Canada in 

 1909 as determined from reports made directly to the Forestry Branch of the 

 Department of the Interior by 2,0S5 operating sawmills. 



The data given and discussed show the quantity and value of each product 

 both by species and by provinces, including also the production by provinces of 

 lumber of different species, imports of hard-wood lumber, and exports of square 

 timber. In most cases comparative data are given for 1908. 



Forest fires in Canada, H. R, MacMillan and G. A. Gutches {Dept. Int. 

 Canada, Forestry Branch Bui. 9, 1910, pp. J/D, figs. 11). — This bulletin contains 

 data showing in a general manner the extent of forest destruction in the various 

 Provinces of Canada, discusses the effects and causes of forest fires, and gives a 

 statement of forest tires occurring in 1909. It concludes with advice to settlers 

 legarding the handling of fires and important points in the forest laws. 



In 1909 approximately 435,000 acres were burned over in the Provinces. Tim- 

 ber and improvements valued at $210,400 were destroyed and $331,821.42 was 

 expended in fire protection and fire fighting. 



Report on forest statistics of Alsace-Lorraine (Beitr. Forststatis. Elsass- 

 Lothr'wgen, 1909, No. 28, pp. 126, dgnis. 11). — A statistical review for the year 

 1909 relative to the administration of the state, public, and community forests 

 in Alsace-Lorraine. The detailed and summarize<^l data deal with forest areas, 

 silvicultural operations, products, revenues, expenditures, etc., including a com- 

 parative summary for each year since 1872. 



The acquisition policy of the Prussian State Forest Administration in 

 West Prussia and Posen, Semper {Ztschr. Forst u. Jagdiv.. JfS (1911), No. 2, 

 pp. 65-96). — ^A historical and statistical account of forest extension and devel- 

 opment in West Prussia and Posen. 



The influence of moisture on the growth of the pine and the fir, E. F. 

 Dameerg (Dnevn. XII. 8"iezda Russ. Est.-Isp. i Vrach. [Moscoiv], 1910, No. 7, 

 p. 269; abs. in Zhur, Opytn. Agron. (Russ. Jour. Expt. Latidw.), 11 {1910), 

 No. 1, p. 120). — Investigations of certain forests in the Novgorod Government 

 of Russia indicate that an excess of moisture retards the growth of the pine 

 and fir. The action of the soil and underground waters is more marked on the 

 pine than on the fir. Experiments showed, that the firs absorbed from 2 to 3 

 times as much water as the pines. 



Seed experiments with Pinus sylvestris, F. Story (Trans. Roy. Scot. Arbor. 

 Soc, 23 (1910), pt. 2, pp. 168-171, pi. 1). — Cooperative experiments are being 

 conducted in Scotland and at a number of forest experiment stations on the 

 European continent to determine the relative value of Scots pine seeds secured 

 from different countries and climatic conditions. 



The results for the first 3 years are given of the tests as conducted at Bangor, 

 Scotland. The seed was collected from trees ranging from 40 to 140 years of 

 age. Thus far Belgium-grown seed from 40-year old trees has shown the best 

 development. Since the results from other stations have not been published 

 as yet, no final conclusions are drawn. 



The reddening' of fresh alder wood, F. W. Neger (Naturw. Ztschr. Forst u. 

 Landw., 9 (1911), No. 2, pp. 96-105, figs. 2). — An investigation similar to that 

 conducted on the greening of fresh linden wood (E. S. R., 23, p. 345) is reported 

 relative to the reddening of fresh-cut alder wood. 



The. surface of fresh-cut alder wood takes on an intensive brownish-red color 

 within a few hours from the time of cutting. The investigation showed that
