in establishing a race which, on crossing with univoltine 

 races, changes the resultant mongrel races into multivol- 

 tines in five or six generations, so that any univoltine races 

 can be made multivoltine in a comparatively short time. 

 Eggs of univoltine Chinese, Japanese, French and Ben- 

 gali races and of a Japanese bivoltine race were sent for 

 cold storage to Guindy, Shillong and Muktesar, and were 

 successfully reared at Pusa in October and March. 



Mulberry silkworm eggs have been supplied to Indore, 

 Gwalior, Mysore, Banganapalle, Travancore, Mahlog 

 (Simla), North-West Frontier Province, Northern Shan

 mulberry seeds and cuttings were also distributed to about 

 19 applicants. One Pusa reeling machine was supplied to 

 the Agricultural Department, New South Wales, and an- 

 other to Indore State. Silk exhibits were sent to various 

 agricultural exhibitions and commercial museums. One 

 rearer and one reeler were sent to the Saunders Weaving 

 School at Amarapura (Burma), and one rearer and one
