30 CULTIVATION OF THE MULBERRY. 



are veins, it is only suitable for the mulberry trees of the 

 country of Khing. [Nong-sang-yao-tchi.] 



The different kinds of mulberry trees are very numerous, 

 we cannot describe them all. 



The best are those of the country of Lou, and of the 

 country of Khing. The mulberry trees of Khing yield a 

 great quantity of fruit, but those of Lou very little. Those 

 of which the leaves are thin, pointed, and divided in lobes, 

 are the trees of the country of Khing. They bear solid 

 and hard leaves. 



The mulberry trees of the country of Lou have round, 

 thick, and juicy leaves. 



The mulberry trees of which the branches and leaves are 

 large, and thick, are a species of those of Lou. 



The mulberry trees of Khing have solid roots and full 

 hearts ; they last for a long time. Those are the kind to 

 be planted. 



The mulberry trees of Lou have less solid roots, and 

 hearts not so full ; they cannot last for any length of time, 

 (dwarf mulberry trees.) Trees called ti-sang are formed 

 from them ; but the trees of Khing have neither as many 

 branches, nor as many leaves, as those of Lou. Branches 

 of the mulberry tree of Lou may be grafted upon them ; 

 they then live for a long time, and yield an abundance of 

 leaves. 



If the mulberry trees of Lou be employed to obtain the 

 species of tree called ti-sang< (dwarf trees) and if they 

 be re-produced by twigs, they propagate without interrup- 

 tion, and last an infinite time.
