AND COLLEGE, PUSA, FOR 1915-16 71 



storage gave satisfactory results on rearing in March, but 

 those sent to Guindy for rearing in October were not suc- 

 cessful. Some of the hybrid multivoltine races, which have 

 been under selective rearing during the last four years, 

 were reared on a large scale and gave satisfactory results, 

 the outturn of reeled silk in all cases being superior to pure 

 multivoltine races but inferior to univoltines. Silk Exhibits 

 were sent to the Agricultural Show at MuzafTarpur and to 

 the Exhibitions held at Chandernagore and Madras; a com- 

 plete working exhibit, showing the whole process of seri- 

 culture from the egg to the finished cloth, was sent to the 

 Madras Exhibition and proved a considerable attraction. 

 A rearer was lent to Rewah State to demonstrate Mulberry 

 silkworm rearing and reeling. The services of Harihar 

 Prasad, Silk Fieldman, were placed at the disposal of the 

 Imperial Agricultural Bacteriologist in connection with his 

 work on investigation of Pebrine in Mulberry Silkworms. 

 A Bengali translation of Bulletin No. 48 (First Report 

 on Mulberry Silk Experiments) was printed during the 

 year, and a second edition of Bulletin No. 39 (Instructions 

 for rearing Mulberry Silkworms) is now in the press. A 

 Second Report on the Mulberry Silk Experiments has been 

 written up. Articles on Mulberry Silk were also contri- 

 buted to the Bengal Journal " Grihastha." 



Visitors to the Silk House included Miss M. L. Cleghorn 

 (on special silk duty under the Government of Bengal), 

 Mr. De Minville, and Mr. H. Maxwell-Lefroy, Imperial 

 Silk Specialist. 



Silk pieces, to the value of Rs. 504-13-0, were sold 

 during the year and the proceeds credited to Government. 



Some experiments were carried out with Tricolyga 

 sorbillans, Wied. (bombycis), the Tachinid parasite of 

 silkworms, in connection with its method of oviposition and 

 breeding-habits. The following caterpillars were exposed 

 to attacks of the flies, viz. : — Mulberry silkworms {Bombyx 

 mori), Eri silkworms (Attacus ricini), Achcea Janata, 

 Spodoptera mauritia, Polytela gloriosce, Cosmophila 

 sahulifera, Papilio demoleus, Utetheisa pulchella, and
