1916] FOEESTKY. 43 



annual report relative to the administration and management of tlie state 

 nurseries and forests in Massachusetts, including also accounts of refores- 

 tation work, private cooperative forestry work, and fire protection work. In- 

 formation is also given relative to the present status of the chestnut blight 

 tmd white pine blister rust and the work of suppressing the gipsy and brown- 

 tail moths. 



Present conditions of applied forestry in Canada, H. R. Macmillan (Quart. 

 Jour. Forestry, 10 {1916), No. 2, pp. 105-123). — An account of the forest policy 

 In the different Provinces of Canada and its effect on practical forestry. 



Silvicultural problems of Canadian forest reserves, B. E. Feknow {Forestry 

 Quart., 14 (1916), No. 1, pp. 14-23). — A paper on this subject presented to the 

 Commission of Conservation of Canada, Ottawa, 1916. The subject matter 

 embraces the results of an inspection made to formulate propositions for in- 

 vestigatory work as a basis for an eventual teclinical management of the re- 

 serves. 



Forest pathology in forest regulation, E. P. Meinecke (U. S. Dept. Agr. 

 Bui. 275 (1916), pp. (jJ). — This bulletin comprises a study of the pathology of 

 some white fir stands located on the Crater National Forest in southwestern 

 Oregon. The purpose of the present study is to show by means of one example 

 the problems in forest pathology as related to forest regulation and to furnish 

 some data for the development of laws leading to the regulation of forests, with 

 special reference to the production of sound timber. 



Regulation of yield is discussed at some leugtli, consideration being given to 

 working plans, rotation, the cutting cycle, cumulative risk, period of transi- 

 tion, condition of timber stock, total loss, and inferior species. The author's 

 methods of investigation are described in detail and a short review of our 

 present knowledge of the plant pathology of white fir is included. The results 

 of the investigation are discussed under tlie general headings of decay in 

 relation to wounds, care of virgin forests, forest regulation through timber 

 sales, marking, and pathological rotation and cutting cycles. 



Abnormal wood in conifers, W. Somerville (Quart. Jour. Forestry, 10 

 (1916), No. 2, pp. 132-136, x>ls. 2). — ^The author here describes and illustrates a 

 form of wood injury occurring in a number of species of young conifers in 

 the early spring wood of the growth of 1912. The injury is attributed to the 

 excessive heat and drought during tlie summer of 1911. 



The costs and values of forest protection, P. S. Lo\'ejoy (Forestry Quart., 

 14 (1916), No. 1, pp. 24-38). — A discussion of forest protection results on the 

 National Forests and in other countries, with special reference to the status of 

 fire protection as a business proposition. The author concludes that the forest 

 business can fully justify the costs of adequate protection, which will prob- 

 ably approximate 20 cts. per acre per year, of which perhaps 10 cts. will be 

 chargeable to fire protection. 



Concerning site, F. Roth (Forestry Quart., 14 (1916), No. 1, pp. 3-13). — A 

 discussion of the importance of site classification as applied to forestry, to- 

 gether with suggestions relative to a basis for such classification. 



In an addendum to this paper by H. A. Parker (pp. 12, 13) data are given 

 showing the close relationship of height and volume to site among the pines. 



The theory and practice of mixing trees, A. T. Gillanders (Quart. Jour. 

 Forestry, 10 (1916), No. 2, pp. 87-104) .—This article deals largely with com- 

 binations of trees suitable for establishing young forest plantations. Brief 

 reference is also made to ameliorative mixtures and deferred mixtures. 



Trees for Kansas, C. A. Scott (Kansas Sta. Circ. 55 (1916), pp. 19, figs. 9).— 

 Lists are given of trees and native shrubs suited to dii'ferent sections and soils 

 in Kansas, together with general directions for the planting and care of trees.
