work of the Committee on Terminology of the Society of 

 American Foresters, by the criticism engendered by the first 

 edition, by four years' experience in teaching forest manage- 

 ment, and by the forest literature produced during that period. 



The author endeavours throughout to keep to the practical 

 view-point, and in doing so he adopts the proper attitude. The 

 first part of his book deals with the foundations of working-plans. 

 In this a considerable amount of attention is wisely devoted to 

 the proper definitions of the terms used. Of chapter II. some 

 6 1 pages describe eighteen methods of determination of cut. 

 The term "cut" here means yield in the sense that it is generally 

 used in British works, namely, the area or volume that may be 

 cut from a forest. We consider the American term preferable 

 and it might be adopted here. Some critics might consider that 

 too much space is occupied in the discussion of these methods, 

 but on the other hand the author deals with them briefly but 

 thoroughly and with appropriate examples, so that the descrip- 

 tions enhance the value of the work. While there is much to 

 be said in favour of Mr Recknagel's method of giving references 

 to works dealing with certain special subjects, one feels that 

 more might be said on rotations. To do so need not, we 

 think, go beyond the limits of a work on forest organisation. 

 Part II. of the book is taken up with " The Practice of Working- 

 Plans." It gives a brief resume of the general working con- 

 ditions and a history of the working methods for the forests of 

 Germany, France, Austria, and America. This forms an 

 important section which should be particularly useful. We 

 feel sure other editions of this book will be called for, and 

 would suggest the inclusion of more details of French manage- 

 ment, which here receive least attention. There is much that 

 is good in French forest systems. 



On the whole this is a volume which, in the opinion of the 

 reviewer, should be in the hands of all forestry students and 

 those who have the framing or application of forest working- 

 plans.

In view of the scarcity of books dealing with the fungous
