FORESTRY OF JAPAN. 2$ 



in such districts as Kyoto and Nara, favourable sylvan features 

 are retained, in fact, some of Phyllostachys Quilioi Riv. found 

 in the private forest in Yamashina, Kyoto, measures 20 centi- 

 metres in diameter and 22 metres in length. Bamboos mostly 

 grow either between the agricultural farms or on the slopes of 

 mounds and do not form the forest covering an extended 

 areas. These bamboo forests are treated by annual selection 

 system and are well fitted to be undertaken by men of small 

 means. 



Of all the bamboos, Phyllostachys mitts Riv. makes the 

 most rapid growth, it sometimes reaching 30 centimetres in 

 diameter and 25 metres in heights. This is extensively culti- 

 vated in such districts as Kyushu and Kii, and is highly prized 

 as the material for various implements. 



3. The forests in the Temperate Poorest Zone are found 

 in districts from the northern half of Honshu to the southern 

 half of Hokkaido, that is, in those regions from 36 to 43 

 5' North Latitude and the yearly average temperature ranges 

 from 6 3 C. to 13 C. The distributions in respect of altitude 

 are found in the height 3,000 metres in Formosa, 1,800 metres 

 in Shikoku, and 1,500 metres in the central part of Honshu, 

 and 500 metres in the southern part of Hokkaido. 



Forests in this zone being quite extensive, many of them 

 have not been explored. Trees of an excellent quality form 

 .a natural forest and this zone is considered to be most valuable 

 in the forestry of Japan. It may be said that the beauty of 

 the Japanese forests reaches its climax in this zone, but owing 

 to the rigorous climate in some parts and the damages from 

 the snow drifts, a sufficient attention must be paid to the
