WHITE 309 



The White Mulberry Tree grows rapidly, 

 reaching a height of thirty or forty feet. It 

 is a native of China, and its leaves are ex- 

 tensively used as food for silkworms. The tree 

 was introduced into America when silkworm 

 raising was being tried in this country, and 

 occurs now spontaneously near houses, especially 

 in the vicinity of long-established silk manu- 

 facturing plants.
