some serious articles on forestry matters, notably one on 

 " Mycology and Bacteriology in Forestry," by Mr John F. V. 

 Phillips, as well as book reviews and a list of new books. 

 There is, perhaps, more of the kind of writing which one expects 

 in students' magazines than is altogether suitable in a journal 

 devoted to a technical subject ; but the publication should, 

 nevertheless, help to promote an interest in the scientific aspects 

 of the subject among the members of the forestry class. 



A Short Manual of Forest Management. By H. Jackson, M.A.

 net. 



In this compact little volume the author covers a wide 

 field which we think could not, under any circumstances, be 

 satisfactorily dealt with in the space at his disposal. 



The introductory chapter is a discussion of the basis of 

 management, choice of species, choice of silvicultural method, 

 choice of rotation, and occupies three pages of the book. The 

 remaining chapters are devoted to the following subjects : — 

 Mensuration and increment, field work, general principles of 

 plan, method of treatment, calculation of the possibility, the 

 working-plan report, and an outline of a plan of management 

 for British estate forests. So brief is the treatment of these 

 subjects, that we do not believe an average student would be 

 able to use the book with advantage, unless he were at the 

 same time to consult other works where a fuller description of 

 the various methods discussed is provided. The author has, 

 perhaps, followed the standard works mentioned in the preface 

 too closely as regards subject matter. It would, in our opinion, 

 have added to the value of the book had he, in describing 

 methods of measuring sample plots and constructing yield- 

 tables, devoted some attention to those used by the Forestry 

 Commission, which are as simple and easily understood as, say, 

 Weise's method, and are more in line with the methods now 

 used in other countries. 



Some confusion might arise from the way in which the word 

 "block" is used in chapter iv. to denote a unit of manage- 

 ment, and, in later chapters, a periodic block.
