different type methods may be applied. The next section 

 relates to the construction of volume-tables. Illustrations of a 

 number of fundamental problems are given, which establish the 

 basis for all volume-table studies. The scaling of logs, and 

 certain precautions to be observed in the case of unsoundness 

 or defects, are clearly brought out in the next section. The 

 methods of determining the contents of stands, with and with- 

 out the aid of a volume-table, are interestingly illustrated. 

 General growth studies in relation to diameter, height, basal 

 area, and volume for individual trees, or as an average for 

 small groups or even extensive areas, form a very interesting 

 section in the book. This is followed by sections on sample 

 plot studies, and studies in growth per cent. The final section 

 is devoted to the problems involved in yield-table studies, and 

 the methods employed in their elucidation. A comprehensive 

 bibliography is given in the Appendix, together with schedules 

 or forms for use in the field. Tables and data series, for use in 

 working out problems included in the text of the book, complete 

 a work which can be commended to both teacher and student.

 the latter " with some addition and corrections." 



No one has taken a keener interest in the progression of the 

 Forest Department than Mr Gamble, and there can be no 

 doubt he has on his table an amount of new information more 

 than sufficient for a complete revision of his Manual of Ti?nbers. 



Mr Gamble complains of want of space, but if the suggestion 

 be permissible there would seem certain directions in which 

 economy might be effected, in order to secure expansion in new 

 or supplementary directions. For example, when the first 

 edition appeared no work of the kind existed previously, and 

 many details had to be given that might with advantage be 

 now omitted. The history of the work, as told by Mr Gamble
