" Schlich's Manual of Forestry: Forest Utilisation." Vol. v. By 

 Professor W. R. Fisher. 2nd edit., 8vo., 840 pp. (Bradbury, Agnew, 

 London, 1908.) 12s. net. 



This is an English translation, by Professor Fisher, of Dr. Carl 

 Gayer's well-known work "Die Forstlienutzung," and has, possibly by 

 permission, been included as volume v. of " Schlich's Manual of 

 Forestry." 



Although an excellent work for Continental foresters, it appeals but 

 little to wood-managers in this country, for floating timber, the utilization 

 of leaves and twigs, resin- tapping, and the disposal and sale of litter 

 hardly come within the scope of British forestry. However, some of the 

 chapters are excellent, and contain much of interest to the manager of 

 our home woodlands, though in early editions of "Brown's Forester" 

 similar matter, much condensed, may be found. 



The chapter on "Industrial Uses of Wood " claims attention as being 

 thoroughly practical and to the point ; but, on the whole, we hardly 

 think that the vast labour in translating the work into English was a 

 necessity — so far, at least, as British forestry is concerned — as few of the 

 operations are practised in our woodlands. 



"Our British Trees, and How to Know Them." By Francis George 

 Heath. 3rd edit., revised, small 8vo., 491 pp. (Routledge, London, 

 1908.) 5.5. 



No one has done more to popularize our woodland trees and shrubs 

 than Mr. Heath. His charmingly written book "Our British Trees," 

 the third edition of which has just been published, is at once not only 

 in a popular, but in a scientific sense as well, one of the most valuable 

 contributions to the subject that has yet appeared. 



With the aid of the text — which, by the way, is quite devoid of 

 unnecessary technicalities — assisted by 250 carefully executed illustra- 

 tions, the student should have little difficulty in recognizing any of our 

 woodland trees or shrubs. The book, too, is of a most convenient size 

 for reference purposes, is well got up and cheap, while it is wonderful 

 what Mr. Heath has crammed into some 500 pages. 



We can strongly recommend this book to every student of our British 

 trees.
