104 NOTES ON THE AGRICULTURE, 



3. — Cocoons of middle size, white in colour, 2.8-3.1 cm. 

 in length 1.6-1.8 cm. in breadth (see PL I, Fig. 3). These 

 cocoons are of Chinese origin from Shantung. 



4. — The long narrow white cocoons with pointed ends 

 of 3.5-4 cm. in length and of 1.3-1.4 cm. in breadth (see 

 PL I, Fig. 4). These are from Shantung. In North 

 Manchuria the white mulberry trees (Morus alba L.) grow 

 wild and are only to be found in the river valleys. These 

 trees are found in several forms and varieties. 



The most common variety is the var. Mongolica Bur. 

 Together with the types of lobed leaves are seen those with 

 large ovate leaves. As shown by the observations of 

 1919-1920, the leaves of the local wild mulberry bud at 

 the beginning of June, and it is due to this that in North 

 Manchuria only one crop of cocoons can be raised.
