factor acts as an excitant. The internal revolution which abridges or 

 suppresses the resting state may be due to acceleration of respiration by 

 the great heat, but this has yet to be determined. — F. A. W. 



Forest Insects : Work of the Bureau of Entomology against 

 Forest Insects. By A. D. Hopkins {Jour. Econ. Entom. i. (1908) 

 6, p. 343). — An historical review of the progress of investigation carried 

 on by the Department is given, and a report upon the work accomplished 

 so far.— F. J. C. 



Forest Planting* in Western Kansas. By R. S. Kellogg {U.S.A. 

 Dept. Agr., Forest Service, Circ. 161 ; March 1909). — For the purpose 

 of determining the various kinds of trees that are suitable for planting in 

 Western Kansas a number of experiments have been undertaken, with 

 highly satisfactory results. 



The details of planting and the species of trees that were used form 

 one chapter. Those on shelter breaks and such useful trees as the honey 

 locust, white elm, mulberry, cedar, and various species of pines show 

 how closely the question of planting up these heretofore uncultivated 

 lands has been studied. There are a few well executed illustrations 

 accompanying the text. — A. D. W. 



Forest Survey of Litchfield and New Haven Counties, 



Connecticut {U.S.A. Exp. Stn., Connecticut, Bull. 162; January 

 1909). — During the Colonial period it would appear that much of the 

 original timber of Connecticut was cut down, and the chief object of this 

 report is to arouse interest in the forest lands and to bring about a well 

 organized system of tree culture. There is much useful information 

 given in this work, as well as several nicely executed illustrations which 

 go far in explaining the text. — A. D. W. 



Forestry Problems of Vermont, Preliminary Statements 

 regarding" the (U.S.A. Exp. Stn., Vermont, Bull. 139; March 

 1909). — The object of this preliminary publication is to explain briefly 

 what forestry is, and to point out the most approved methods of tree- 

 planting, improving woodland, and dealing with the crop. Natural 

 regeneration is also attended to. The instructions given are practical 

 and to the point, while the illustrations of tree nurseries and the tables 

 of forest products and lumber exported from Vermont greatly increase 

 the value of the publication. — A. D. W. 



Forestry, Quarterly Journal of (April and July, 1909). There 



is much useful matter in these parts of the " Journal of Forestry," and 

 the editors are to be complimented on their endeavours to resuscitate the 

 original " Journal," whose most useful career so unfortunately terminated 

 in 1886. 



Magazines devoted to forestry pure and simple have had rough times 

 at the hands of those whom they were directly intended to instruct and 

 help, and even Mr. Robinson's laudable attempt in " Woods and Forests " 

 did not meet with the support it so well deserved.
