(2) The radial section of the wood has the great resistance (do). 



(3) The differences in resistance between the cross and radial 

 section of wood are generally more remarkable in the case of broad- 

 leaved species such as Shirakashi (Quercus myrsincefolia, Bl.), Buna 

 (Fagus sylvatica. L. var. Sieboldi. Maxim.), Sakura (Prunus Yamasakura, 

 Sieb. var. Spontanea, Max.) and Nara (Quercus crispula, Bl.) than in the 

 case of Sugi (Cryptomeria japonica, Don.), Hinoki (Chamaecy parts obtusa, 

 S. et Z.), Akamatsu (Pinus densiflora, S. et Z.) and other coniferous trees. 



VIII. Electric Resistance of Woods and Specific Gravity 



Woods having high specific gravity offer far less resistance than 

 those having low specific gravity, so long as the amount of moisture 

 ■content is same.
