History of the lumber industry of America, J. E. Dkkebaugh (Chicago, 1907, 

 vol. 2, pp. XIII +655, pis. 16, dgm. 1, map /).— A'ohime 1 of this work (E. S. R., 

 17, p. 1073) contains a large amount of general information relative to the his- 

 tory of the lumber industry in North America, together with a detailed account 

 of the industry in eastern Canada. 



The present volume is devoted principally to the history of the white pine in- 

 dustry in the United States, in which the lumbering operations are traced 

 beginning with the State of Maine, through the New England States, and across 

 New York and Pennsylvania. Attention is also given to other species which 

 haA-e been lumbered with white pine in the order of their occurrence in the dif- 

 ferent regions. 



The sprout forests of the Housatonic Valley of Connecticut, G. F. Schwarz 

 (Forestry Quart., 5 (1907), No. 2, pp. 121-153, pU. 3, figs. 7, dgms. J,).— A sylvi- 

 cultural study of the sprout forests of the Housatonic Valley, undertaken for and 

 published with the permission of the Forest Service of this Department. Three 

 distinct types of growth were found to occur, this being due to differences in 

 soil conditions and the relative position on the slopes. 



Tabulated data for the three forest types are given and discussed relative to 

 the average number of trees per acre, diameter and average age of trees, the 

 capacity for sprout production, the effects of light and shade in the develop- 

 ment of spi'outs in the different species, and the amount and character of repro- 

 duction and estimated yield of sample areas, together with diagrams showing 

 the rates of height, diameter, and volume growth. 



Forest planting- on the northern prairies, J. M. Fetherolf ( U. S. Dept. Agr., 

 Forest Serv. Circ. l-'i5, pp. 28).— Results of a study of the existing plantations 

 in the northern prairies, conducted by the Forest Service with the view of deter- 

 mining the species best adapted for planting in that region, are presented. 



Brief notes are given on the location, topography, soil, climate, and early 

 plantings in the northern prairies. Tree planting is considered both for protec- 

 tive and for commercial purposes, and a list is given of trees recommended for 

 planting, together with a detailed discussion of the merits of each species based 

 upon general observations as well as upon actual measurements of a number of 

 planted groves. The details of planting are also considered, including planting 

 material, source of plants, preparation of soil, mixing species, spacing, cultiva- 

 tion, pruning, thinning, and regenerating groves. 



California red fir in the Tahoe forest reserve, M. R. Pratt (Forestry Quart., 

 5 (1907), No. 2, pp. 159-165). — Observations on this si)ecies as it occurs in the 

 Tahoe forest reserve, including its botanical characteristics, habitat, associated 

 species, reproduction, diseases and enemies, commercial value, and considerations 

 in marking for cutting with a view of affording protection against wind-throw, 

 retarding snowslides on steep slopes, insuring abundant seeding, and leaving a 

 nucleus for future crops. 



The maritime pine or Pinus maritima, F. Albert (El Pino Maritimo o Pinus 

 Maritima. Santiago de Chile: Govt., 1907, pp. 58, figs. 30). — A monograph on this 

 species of pine, which the author recommends for planting in certain coastal 

 regions of Chile. The work includes a list of common names, botanical syno- 

 nyms, and a botanical description of the species, together with an account of 

 its range and geographical distribution, varieties, the timber and its uses, the 

 methods of extracting resin in A-arious countries, methods of propagation, sylvi- 

 cultural treatment, exploitation, etc., with special reference to Chile. 



Philippine woods, F. W. Foxworthy (Philippine Jour. >SV'i, 2 (1907), No. 5, 

 pp. 35}-.'i0'i. figs. 55). — This jiaper contains a general and technical discussion 

 of woods, including wood structure, gross morphology, minute anatomy, phys-
