FORESTRY. 



Forest conservation for States in the southern pine region, J. G. Peters 

 {U. S. Dept. Agr. Bui. S64 {1916), pp. i^).— This bulletin points out the essential 

 elements in the various forest problems that confront the States in the southern 

 pine region, shows how these problems are interrelated, and discusses methods 

 for solving them, information being given relative to conservation legislation 

 already in force in the different States and the nature of the assistance tlie 

 Federal Government is prepared to offer to forestry in these States. 



Renewing the shelter-belt, G. B. MacDonald {Iowa Sta. Circ. 27 {1916), 

 pp. 16, figs. iS).— This circular describes the following five methods for renew- 

 ing the shelter-belts in Iowa: Regeneration from one side, regeneration from 

 two sides, regeneration by clear cutting, regeneration by alternate rows, and 

 regeneration by under planting. Each method is illustrated with drawings ex- 

 plaining how the work is carried on for a shelter-belt of average size, and a list 

 is given of tree species suitable for use in the method. 



Report on the activities of the Swedish Institute of Experimental For- 

 estry during the 3-year period, 1912-1914, G. Schotte and H. Hesselman 

 {Meddel. Stat. Skogsfdrsoksanst. {Mitt. Forstl. Vers. Anst. Schwedens), No. 12 

 {1915), pp. 9-70, I-XX, fig. 1). — In addition to a brief statement of progress 

 ma>!e in various divisions of the institute a schedule of investigations and other

Progress report of forest adnjinistration in the Province of Assam for the 

 year 1914r-15, A. R. Dicks and W. F. L. Tottenham {Rpt. Forest Admin.

Two forest arboretums near Brussels, D. E. Hutchins {Trans. Roij. Scot. 

 Arbor. Soc, 30 {1916), pt. 1, pp. 1-14). — Notes are given on the growth of vari-

The development of the vegetation of New York State, W. L. Beay {N. Y. 

 State Col. Forestry, Syracuse Univ. [Pubs.}, 16 {1915), No. 2, pp. 186, pis. 2. 

 figs. 52). — This study comprises as a whole an analysis of the history and pres- 

 ent aspects in the development of the native vegetation in New York State, 

 together with some consideration of the status of vegetation as modified by 

 human action. The study was conducted with reference to its subsequent value 

 in investigations along various phases of forestry and allied lines of work, such 

 as fish and game propagation and protection and the control of injurious in- 

 sects and fungi. 



The subject matter is treated at length under the following general headings : 

 A general review of classification, growth forms, and plant associations ; land- 

 marks in the geological history of vegetation ; the glacial period and its effect 

 upon vegetation ; modern aspects of the plant geography of New York ; the con- 

 tent, zonal relations, zonal features, and extra-continental relations of the New 

 York flora ; the sources of New York flora in general ; development of vegeta- 

 tion as influenced by the substratum and the resulting influence upon the sub- 

 stratvun ; the bog sequence of vegetation ; the development of vegetation upon 

 a substratum subject to prevailing water deficit ; the resemblance between heath 

 bog and pine barren vegetation; general survey of xerophytic succession in 

 New York ; Uie development of mesophytic vegetation ; climax vegetation ; and
