FORESTRY. 



Forestry in New England, E. C. Hawley and A. F. Hawes (iN^ew York mid 

 London, 1912, pp. XV-\-Jil9, pis. 2, figs. i^O).— Part 1 of this work furnishes 

 the woodhmd owner a brief survey of the whole field of industry and provides 

 him with a working knowledge of forestry. The successive chapters discuss 

 silvics, silvicultural systems, silvicultural characteristics of the important New 

 England trees, forest planting and seeding, improvement cuttings, injuries from 

 animals, forest insects and fungi, forest fires, timber estimating and valuation, 

 and growth of trees and forests. 



Part 2 deals with New England forests and their management, the subject 

 matter being discussed under the following chapter headings: The original 

 forests and their early development, present forest conditions, the spruce 

 region, the northern hardwoods region, the white-pine region, the sprout hard- 

 woods region, the progress of forestry in New England, and the yield to be 

 expected from New England forests under proper management. 



Report on timber conditions around Lesser Slave Lake, D. R. Cameron 

 {Dept. Int. Canada, Forestry Branch Bui. 29, 1912, pp. 5Jf, pi. 1, figs. 17).— 

 This comprises a detailed report of a reconnoissance survey made during the 

 summer of 1911. The general conditions of the region are described and the 

 country examined is discussed by districts. Proposed forest reserves are sug- 

 gested and a scheme of fire protection, illustrated by a map, is also submitted. 

 A number of tables summarizing the important information about the country 

 are appended. 



The forest trees of Britain, C. A. Johns, revised by G. S. Botjlgeb {London 

 and Brighton, England, 1912, 10. ed., pp. XIV+^31, pis. 32, figs. 152).— A re- 

 vised edition of the late author's work, which is essentially a handbook of 

 popular information relative to the lore, distinguishing characteristics, adapta- 

 tion, and planting value of the principal trees and shrubs grown in England. 

 See also a previous note (E. S. R., 26, p. 642). 



Notes on Kerry woods, illustrating methods of collecting and utilizing 

 information for a forest survey, R. L. Robinson (Jour. Bd. Agr. [London], 

 1912, Sup. 9, pp. 64, pis. 7, figs. If). — The investigations described were primarily 

 undertaken with the object of obtaining some accurate figures relating to the 

 growth of timber in one of the more hilly districts of Wales. The scope of the 

 work was broadened in order to settle the lines on which a forest survey on a 

 large scale should proceed. 



The introductoi-y chapter deals with the topography, climate, geology, and 

 soil of the Kerry woods. The succeeding chapters discuss the methods of 

 measurement and details of growth of different species, together with the 

 utilization of the data for the survey. 



Complete yield tables for British woodlands and the finance of British 

 forestry, P. T. Maw (London, 1912, pp. XII+108, figs. 56).— This comprises the 

 results of the author's investigations concerning the growth of timber in Great 

 Britain and the financial returns to be obtained therefrom. The tables as 

 given for both deciduous and coniferous trees on different qualities of soil 

 show for various aged stands the amount and value of thinnings removed, crop 

 left after thinning, increment, land rentals per annum from date of planting, 

 and the annual income from a normally stocked forest. 



Taxation investigations.— Ill, Determination of the form of standing trees, 

 T. JoNsoN (Skogsvdrdsfor. Tidskr., 1912, Fackafd., No. 4, PP- 2S5-275, figs. 11).-— 

 The author's method of determining the total cubical content of standing trees, 

 yiel(^ and increment for the purpose of taxation is describetl.
