work, yields in major and minor forest products, revenues, expenditures, etc.,

Progress report on forest administration in the Northwest Frontier Prov- 

 ince for the year 1914-15, W. Mayes {Rpt. Forest Admin. Northwest Frontier 

 Prov., 191.'f-1.5, pp. -i+II+l^+XXIV). — ^A report similar to the above relative 

 to the administration of the state forests of the Northwest Frontier Province 

 for the year 191-^15. 



Report of the department of forestry for the year ended June 30, 1915, 

 R. Dai3Ymple-Hay {Rpt. Forestry Dept. N. S. Wales, 1915, pp. 6, pis. 6).— This 

 is the usual progress report relative to the administration and management of 

 the state forests and forest nurseries of New South Wales, including informa-

The native and cultivated forest trees and shrubs of the Misso\iri River 

 basin, L. H. Pammel, G. B. MacDonald, and H. B. Clark (Proc. Iowa Acad. 

 Sci.. 22 {191.5), pp. 23-56, pis. 12). — In this paper the authors present a cata- 

 logue of trees and shrubs of the Missouri River basin in western Iowa and 

 eastern Nebraska. Introductory considerations deal with the topography and 

 soils of the region, the range and ecological distribution of trees in the area 

 surveyed, and the origin of the tree flora. 



A mill scale study of western yellow pine, H. E. McKenzie {Cal. Bd. For- 

 estry Bui. 6 {1915), pp. Ill, figs. 222). — The study here reported is bused upon 

 919 trees ranging from 20 to 44 in. in diameter breast-high. A complete 

 analysis of the quality and quantity of lumber produced from these trees, also 

 from the butt logs (the best part) and the top logs (the poorest part of the 

 trees) was made. The measurements secured in this work are here presented, 

 together with deductions made therefrom, in a series of curves and tables with 

 a view to throwing some light on the lumbering value and the best time to cut 

 trees of various sizes. 



Colonial plants. — Latex and resin yielding plants, H. Jumelle {Lcs Cul- 

 tures Colonialcs. — PUnxtes a Late.r et a R^siues. Paris: .J. B. BniUii:re & Sons, 

 2. rev. cd., vol. 7, 1915, pp. 119, figs. ^1). — This is part 7 of the author's revisetl 

 work (see p. 829). The jtrosent part discusses various rubber and resin 

 yielding plants with reference to their botany, exploitation, culture, and 

 uhlization. 



[Papers on rubber culture and the rubber industry] {Introductory Papers 

 luternat. liuhhcr Cong. Batavin, 191.'i. pp. [191]. fig. 1). — This comprises .some 21 

 papers on various phases of rubber culture and the rubber industry, which were 

 prepared for the International Rubber Congress and Exhibition at Batavia in 

 Septemlier, 1914. Certain of the present papers are classed as introductory 

 papers and others as papers prepared for but not included in the rubber book 

 issued by the congi'ess (E. S. R.. .3.3, p. 50). 



Manurial experiments with young nibber at Kuala Lumpur, E. G. Spring 

 {Agr. Bui. Fed. Malay States, ^ {1916), No. J^, pp. 105-110).— DaXa are given on 

 the fourth season's results with various combinations of lime, nitrogen, phos- 

 phorus, and potash (E. S. R., 32. p. 339). 



The fertilizers in this experiment were applied at the beginning of the 

 first and third years. They appeared to have had a stimulating effect as re- 

 gards growth for about a year after each application. After this there seenieii 

 to be a slight reaction as compare<l with the control plats. Over the whole 

 4-year period tlie total increnso in tlie manured plats in every case exceede«l 

 that of the controls. No delinite conclusions are to be drawn until the trees 

 are tapped.
