Osier culture, F. Knotek (Arb. Deut. 8ek. Landeskult. Rat. Konigr. Bohmen, 

 No. 18 (1914), pp. 21, figs. 10). — Practical Instructions are given for the culture 

 of basket willows. 



The coniferous forests of eastern North America, R, M. Harpeb {Pop. Sci. 

 Mo., 85 {191Jf), No. Jf, pp. 338-361, figs. 16).— This comprises a descriptive 

 account of the important coniferous forest types of eastern North America. 

 Each type is considered with reference to its geographical distribution, correla- 

 tions with soil, water, climate, fire, etc. Notes are also given on the economic 

 aspects of the trees and the regions in which they grow. 



The role of aspen in the reforestation of mountain bums in Arizona and 

 New Mexico, G. A. Pearson (Plant World, 17 (1914), No. 9, pp. 249-260, figs. 

 2). — Experiments conducted for several years under the direction of the Fort 

 Valley Station, Flagstaff, Ariz., in planting Douglas fir in aspen thickets and 

 adjoining openings have demonstrated that aspens are of considerable value 

 in reforestation. The superiority of the aspec-covered areas over the openings 

 is attributed mainly to a reduction in transpiration. The value of aspens in 

 regulating transpiration from fir seedlings appears to more than compensate 

 for the loss in soil moisture taken up by the aspen trees. 



Tree distribution in central California, W. A. Cannon (Pop. Sci. Mo., 85 

 (1914), No. 5, pp. 411-424, figs. 4). — The author here briefly outlines the root 

 characters of the three most prominent species of oak of central California 

 with special reference to their ability to reach ground water at different depths, 

 and points out the intimate relationship between root character and the charac- 

 teristic local distribution of the species. 



Timber conditions in Little Smoky River Valley, Alberta, and adjacent 

 territory, J. A. Doucet (Dept. Int. Canada, Forestry Branch Bui. 41 (1914), 

 pp. 52, figs. 16). — In continuation of a previous report (E. S. R., 27, p. 646) a 

 report is given on the work done during the summer of 1912, completing the 

 reconnaissance and delimitation survey of the proposed Lesser Slave Lake

 are given relative to the protection of these forests from fire. A map accom- 

 panies the report. 



Timber and soil conditions of southeastern Manitoba, L. C. Tilt (Dept. 

 Int. Canada, Forestry Branch Bui. 45 (1914), pp. 36, pi. 1, figs. 13). — This 

 embraces the results of a survey conducted under the direction of the Forestry 

 Branch of the Canadian Government in 1912. A considerable proportion of the 

 country was found suitable for a forest reserve and a map is included in the 

 bulletin showing this tract. 



The forests of Madagascar: Their characters, resources, and conservation, 

 R. Badin (Bui. Econ. Gouvt. Gen. Madagascar, 14 (1914), I, No. 1, pp. 33-58). — 

 A descriptive account of the forests of Madagascar, including information rela-

 number of tannin-yielding acacias, including some other tannin-yielding species, 

 together with analyses of various parts of the tree with special reference to

The tapping of pines and resin exploitation in Tonkin, CaeriI;be (Bui. 

 Econ. Indochine, n. ser., 17 (1914), No. 108, pp. 329-335, figs. 3).— A short
