The artificial sowing of seeds is used side by side with 

 the natural growth, chiefly in places where the natural growth 

 is inadequate. According to the nature of the land and forests, 

 this method is sometimes solely used. In this case, different 

 ways of sowing are adopted such as sowing in strips, broad 

 cast sowing, and sowing on ridges. Such trees as the Kashiwa 

 (Quercus dent at a Tluuib.) which is planted with the object of 

 preventing sand drifting are cultivated according to this 

 method. Such trees as Kuri {Casta nca vulgaris Lam. -jar. 

 japonica Dc.) and Kashi [Quercus species) are also cultivated 

 by artificial sowing. In the northern part of Honshu, Aka- 

 matsu {Pinus densiflora S. ct Z.) has been successfully raised 

 by the method of sowing in strips, but at present, this method 

 is only adopted in rare instances. 



The method that most extensively prevails is that of the 

 planting of seedlings. A greater portion of the State, and the 

 Imperial forests is formed by this method. Of late, this 

 method has come to be much used in the forests owned by 

 private individuals. According to this method, the seedlings 

 of 2 or 3 years' growth are transplanted to the forest land; 

 the number of these seedlings planted per cho varies according 

 to their species, but ordinarily speaking, they range from 3,000 

 to 6,000 per cho. Owing to climatic and other relations, the 

 healthy growth of these seedlings is not always assured so 

 that in one or two years afterward about 10 or 20^% of these 

 seedlings are supplemcntarily planted. There is not a single 

 kind of the valuable trees of Japan that has not attained success
