452 EXPEKIMENT STATION RECORD. [Vol.35 



forest trees on denuded lands and on worn-out agricultural lands. Thirty-five 

 typical forest plantations in various part of the State were studied with refer- 

 ence to conditions of growth and rate of growth of the trees. The subject 

 matter is presented under the general headings of conditions for establishing 

 a successful forest plantation, results of forest planting, and causes of injury 

 to plantations. 



Possibilities of private forest management in New York State, O. H. Guise 

 {New York Cornell Sta. Bui. 375 {1916), pp. 697-746').— This bulletin reports 

 a study of the present condition of private forestry in New York State, dis- 

 cusses the possibilities of future management, and presents data showing 

 what rates of interest under average conditions may be obtained on invest- 

 ments in different classes of timber suitable to management in the State. 



Briefly summarized it is concluded that white pine and chestnut are capable 

 of yielding the greatest returns as an investment and are at present the only 

 trees, with the possible exception of red pine, that can be safely gi-own for 

 profit. The danger of bark disease may eliminate chestnut. Inasmuch as a 

 return of scarcely more than 6 per cent can be realized after from 40 to 50 

 years from the time the initial investment is started, the possibilities of 

 private forestry, on a small scale at least, are not encouraging. 



Operations and costs on Pennsylvania state forests, N. R. McNaughton 

 (Forestry Quart., U {WIG), No. 2, pp. 236, 237).— A summary to date is given 

 of the work done and operation costs on the Pennsylvania state forests. 



The reforestation of the antarctic woods, G. T. Schuster {Bol. Min. Agr. 

 [Buenos Aires'], 20 {1916), No. 1-2, pp. 78-102).— An account of the present 

 condition of forest areas in southern Argentina, together with suggestions 

 relative to reforestation of this region. The Oregon pine {Pseudotsuga taxi- 

 folia), which is believed to be suitable for this purpose, is considered in detail 

 relative to its botany, characteristics, wood, habitat, and silvicultural require- 

 ments. 



Seed testing- with the Jacobsen germinating apparatus at the Danish Seed 

 Control Station, trans, by J. A. Laksen {Forestry Quart., U {1916), No. 2, pp. 

 273-276, fig. 1). — A short descriptive account of seed testing practices at the 

 Danish Seed Control Station, including a list of papers related to this ques- 

 tion issued by this station. 



An improved form of nursery seed-bed frame, D. R. Beewsteb {Forestry 

 Quart., U {1916), No. 2, pp. 183-1S7, pi. 1).— The author here illustrates and 

 describes a portable, take-down nursery seed-bed frame which has proved to 

 be well adapted for use at the forest experiment stations. 



A practical application of Pressler's formula, A. B. Recknagel {Forestry 

 Quart., 14 {1916), No. 2, pp. 260-267). — In this paper the author presents data 

 showing how Pressler's well-known formula may be used in a practical way 

 to determine the current annual increment in mixed selection forest and from 

 this to work out the regulation of the cut. The data given were secured from 

 work done by Cornell University students in the Catskills and Adirondacks 

 during 1914 and 191.5. 



Business rate of interest and rate made by the forest, F. Roth {Forestry 

 Quart., lit {1916), No. 2, pp. 255-259).— A brief discussion of the position of 

 forestry as a business investment as compared with other business enterprises. 



Summary of costs on a flume and railroad logging operation in northern 

 California, N. C. Brown {Empire Forester, 2 {1916), No. 1, pp. ^l-U, figs. 2).— 

 Data are given showing the cost of logging and manufacturing lumber on a 

 large tract in northern California. The experience of several years shows 

 that the total logging and manufacturing charges amount to $13.65 per 

 1,000 ft. b. m.
