74 FORESTRY OF JAPAN. 



Sieboldi Maxim.), Shikimi {Illicium Anisatum L.), Tsubaki 

 {Then japonica jVois.), Abura-giri (Aleurites cor data Mnell. 

 Arg), Inugaya [Cephalotaxus dmpacca S. et Z.), Kurumi 

 Jnglans Sieboldiana Maxim.), etc. arc gathered as the material 

 for vegetable oil. High wages are being paid for these nuts 

 gathering and in the nut gathering season farmers often get 

 three times as high wages as their ordinary pay. With the 

 development of the mechanical industries the demand of 

 vegetable oil has greatly increased, and consequently the 

 gathering of these nuts is making a gradual increase. The 

 output of nuts during 1907 was over 159,700 koku and was 

 valued at over 555,200 yen. 



7. Bark The bark of Kashiwa {Qnercus dent at a T/in/ib.), 

 has hitherto been used as a dyeing material or for the tanning 

 of skins but lately the demand for it has greatly increased. 

 This bark is at present being supplied by the forests in Hok- 

 kaido and the northern part of Japan. There are, however, 

 no forests made artificially for the purpose of producing the 

 bark, but this material is obtained from the forests of a natural, 

 growth. The bark of Han-no-ki {Alnns japonica S. et Z. ), 

 Tsuga ( Tsnga Sieboldi Carr.), Kuri (Castanca vulgaris Lam. 

 var. japonica Dc), Nobu-no-ki [Platycarya strobilacea S. et Z.), 

 Nara {Oncrcus species.), and Shii {Pasania enspidata Oerst.) are 

 also used in the same way as the Quercns dentata Thnnb. The 

 output of bark during 1907 was over 4,4cSo,6oo kin, valued at 

 over 71,800 yen. 



Resides these, there are many minor-products of forests 

 such as bark of Sugl (Cryptomeria japonica Don.), Hinoki 

 iChamaecyparis obtnsa S. it Z., and the Sheath <>f bamboo,
