but to the practicing forester it would be of much more value if in 

 the text were given a good description of the conditions and circum- 

 stances under which the data were gathered. Such descriptions are 

 necessary for the application of the data in the field.

Local Yield Tabic for the Fir (Abies sachalinensis). By Dr. F. 

 Koide and H. Nakashima. V^ol. T, No. 8, Research Bulletin of the 

 College Experimental Forests. Hokkaido Imperial University, Sapporo, 

 Japan, March, 1921. 



This bulletin, following an introduction, gives sites and stand and 

 meterological data by months and years. There follows a description 

 of the sample plots and the selection of the "standard" (mean sample) 

 trees. The data are given in detail for each sample plot according 

 to compartment, sub-compartment, slope, soil (character and depth, 

 composition and moisture content), and site quality. 



The authors then describe the method of calculating the volumes of 

 the sample plots, of which there are twenty-seven. This is according to 

 th^ usual methods followed in making yield tables. The tables fol- 

 low — in the usual form — for three (not five) site qualities. The va^ 

 rious graphs are added. 



This fir is used chiefly for paper pulp in Japan and to some extent 

 for construction and boxes. 



The next chapter is a detailed correlation of the volumes of trees 

 of the same height and different diameters or of the same diameter 

 and different heights. 



Dr. Terazaki is one of the two Japanese experts in measuration work 

 attached to the Imperial Forest Experiment Stations.

Volume Tables for Thujopsis dolabrata {"Hiba'') and Basis on 

 which it May he Constructed. By Wataru Terazaki, Doctor of For- 

 estry, Forest Experiment Station, Meguro, Tokyo, Japan. Reprint 

 from the Bull, of For. Exp. Sta. No. 19, 1930. 



The first chapter covers Introduction, Materials of Investigation. 

 The tables are headed Diameter (in feet and hundredths), height and 

 volume (in ten cubic feet to 4 decimal points), all grouped by 6-foot 

 height classes. These tables are based on the measurement of 1,963 

 trees.
