IV. Application to the Construction of the Yield Table 



In 1907, I showed in Bulletin No. 4 of the Forest Experimental Station 

 that similar considerations apply to the construction of a yield table of 

 the normally stocked, pure, even-aged stands for Larix leptorepis and to the 

 discussion of the relative growth of stands for Cryptomeria with respect to 

 sort and degree of thinning, commonly in use in the district of Yoshino, 

 Nara Prefecture. Furthermore, in 1915, the formulae and relations with 

 respect to the factors of the growth of stand described in the previous 

 parts, were tested by application to the construction of a yield table on the 

 normally stocked, pure, even-aged stands of different forms of density of 

 Cryptomeria in the Main Island and Kiushu, and reported in Bulletin No. 

 11 of the Forest Experiment Station. In this short communication I have 

 thought it would be advisable to report briefly the results of a fairly 

 accurate application of the formulae and relations stated fully in the 

 Japanese article. 



I have collected the data from 153 stands of Cryptomeria in the Main 

 Island and Kiushu. These may be summarised as follows :
