The value of normal yield tables in forest management, E. Ostwald 

 {Ztscltr. Foist. It. Jaydic, .',1 (l!)09), Xo. t, pp. l.'f-^7). — The author advances the 

 oi)iiii(in th.if iiKisf of the yield data which have been gathered in experimental 

 work have been formulated to meet the needs of scientific investigators ratlier 

 than practical foresters. With the view of illustrating a system of formulating 

 the data which shall be of value to practical foresters, he i)resents and discusses 

 a series of S yield tnbles which are based on the yield data secured by Schwap- 

 pach in his work with the iiinc ( K. S. K., 7, p. iXil ; 2(t, p. ()t4). 



Report on forest conditions in Delaware and the forest policy for the State, 

 W. D. Sterrett {Dclaicare Sta. Bui. 82, pp. 3-5H, fiys, JO, map I). — liesults are 

 given of a cooperative study of forest conditions in Delaware made bj' the 

 station and the Forest Service of this Department with the purpose of recom- 

 mending practical measures for the management of the various classes of wood- 

 land and of formulating a definite forest policy for the State. 



The two general lines of action recommended and discussed are the encour- 

 agement of forestry by private owners and the establishment of State forests. 

 Lists are given of species indigenous to the State, grouped according to their 

 commercial importance, together with remarks on their occurrence, and sug- 

 gestions relative to the establishment and management of forest plantings. 



Most of the land in the State was found to be too valuable for agricultural 

 purposes to be used for growing forests. The author points out the desirability 

 of the woodlot on the farm, however, and also advises the planting of trees to 

 serve as wind-breaks and shelter belts. Since Delaware has a climate and 

 soils well adapted to extremely rapid tree growth and a favorable market for 

 forest products, it is concluded that timber growing, with careful treatment, 

 can be made a profitable enterprise anywhere in the State on lands not valued 

 at more than $15 per acre for agriculture. 



Report of the State forester of Wisconsin for 1907-8, E. M. Griffith (Rpt. 

 State Forester Wis., 1907-8, pp. 5-133, pis. 11). — This report discusses the con- 

 dition of 'State forest operations for 1907-S, and contains suggestions for han- 

 dling local forest problems of various kinds, such as reforestation, fire protec- 

 tion, timber trespass, forest taxation, and necessary legislation. An appendix 

 contains the State forestry laws for the years 1905 and 1907. 



Forest trees of the Pacific slope, G, B. Sudworth {JJ. 8. Dept. Agr.. Forest 

 Serv., 1908, pp. .'flfl, pis. 2, figs. 201). — This volume, now withdrawn from circu- 

 lation, contains an account of the tree species, 150 in all, known to inhabit some 

 part of the region including Alaska, British Columbia, Washington, Oregon, 

 and California, many of which trees occur wholly within this region. Since 

 the work is nontechnical in character, the artificial keys of families, genera, and 

 species are omitted, and the many full-sized illustrations of the leaves, fruits 

 and seeds have been made a special feature for the purpose of identification. 

 Each species is considered relative to its distinguishing characteristics, longev- 

 ity, range, occurrence, climatic conditions, tolerance, and reproduction. 



The afforestation of poor agricultural soils, K. J. Moller {Aufforstiiiig 

 Lutuliciitschaftlich Minderwertigcii Bodens. Berlin, 1908. pp. IV+102). — This 

 work, which was given a prize by the department of the interior of Saxony, 

 consists of a study of the expediency of afforesting lands which are either 

 poor or of no value for jigricultural purposes with special reference to small 

 estates. The subject is discussed under 2 general headings. In part 1 the 

 author considers to what extent the afforestation of these lands is advisable. 

 In part 2 he discusses ways and means for afforesting such lands on small 

 estates. An appendix contains regulations and sample statutes for the organiza- 

 tion of forestry associations.
