FORESTRY. 



History of forestry, B. E. Fernow {Toronto, 1909, pp. VIII +438). —Thin 

 cousists of a brief history of forestry in Europe, the United States, and other 

 countries. It has been prepared largely to l)rlnf; together the information now 

 scattered and mostly inaccessible to English or American readers and is based 

 upon a series of lectures delivered before the students of forestry in Yale 

 University. 



Silviculture, A. Fron (Si/lriciiltiirr. ParLs, 1909, pp. Y-HJ. flf/x. 9'/). — The pres- 

 ent etiition of this encycloi)edic work (E. S. R.. 15, p. 480) has been largely 

 rearranged and modified in many parts of the text. 



Fart 1, under the heading, the forest in general and its constituent elements, 

 discusses the life of the tree in general, forest species, forest and woodlands, 

 various forms of woodlands, the status of forestry, general utility of forests, 

 and forest products and industries. Part 2 takes up practical silviculture 

 under the subdivisions natural and artificial regeneration, cultural operations, 

 forest management, and the wooded domain and its constituent elements. Part 

 3 comprises special studies of the coppice, coppice with standards, and high- 

 forests systems. 



Native trees of Kentucky, Sarah W. Maury {[Louiscillc], 1910, pp. l.'/O, 

 2)ls. 3, fl(/.s. J/.'i). — A popular handbook on the native trees of Kentucky, describ- 

 ing the general characteristics of each species, the wood and its uses, and the 

 tree, bark, leaves, and fruit. Both common and botanical names are given, 

 together with illustrations of fruiting branches in many cases. 



A new cypress for Arizona, G. B. Sudworth {Arner. Forcfittij, 16 (1910), 

 No. 2, pp. 88-90). — The author describes a new species of cyju'ess recently 

 found on the north slope of the Verde River Canyon and for which he proposes 

 the name Cupressiis glabra. The wood of this cypress is said to be exceedingly 

 durable in an unprotected state as compared with the wood of C. arizonica, 

 which is not of particularly lasting quality. 



Studies in the vegetation of the Philippines. I, The composition and 

 volume of the dipterocarp forests of the Philippines, H. N. Whitford 

 {Philippine Jour. ScL, C. Dot., Jf {1909), No. .'/, pp. 699-726, pis. 7). — A study of 

 the composition and volume of the dipterocarp forests in different sections of 

 the Philippines, with tabular data on some of the more dominant trees, showing 

 the number of trees or cubic meters of wood per hectare and the percentage 

 each species forms of the stand. 



The virgin forest area of the Philipinnes consists of approximately 40,000 

 square miles, or about one-third the total area, and members of the dipterocarp 

 family predominate in 7Ij per cent of these forests. From the forester's and 

 lumberman's standpoint, they are divided into three tree groups, the hard 

 durable yacals, the ar)itongs, and the lauans, the second group corresponding to 

 the hard pines in general mechanical properties and the last to the .soft pines. 

 In studying the volume of these forests, bulk and annual increment were both 

 taken into consideration. The author concludes that if measured in bulk alone 

 some temperate regions show greater success in forest growth than the Philip- 

 pines. When bulk and annual increment are combined, however, Philipijine 

 forests compare favorably with forest growth in temperate regions. 



Preliminary study of the woods of the Ivory Coast, A. Chevalier {Vcg. 

 Utiles Afriquv Trop, Franc., 1910, No. 5. pp. .il'i, map 7). — This consists of a 

 preliminary report of a survey of the forest flora of the Ivory Coast. 



Part 1, which is introductory in its nature, deals with the history of various 

 missions to the Ivory Coast and lines of study pursued. Part 2 discusses the 

 actual exploitation of the forests. Part 3, which is the most important sec-
