60 REPORT OF THE AGRICULTURAL RESEARCH INSTITUTE 



Mr. C. C. Ghosh visited the Sepaya Farm in September 

 1914 to examine the indigo planted in connection with 

 Psylla experiments. 



Mr. G. R. Dutt toured in Southern India from 29th 

 March to 17th May 1915 to collect information and speci- 

 mens of insects, especially Hymenoptera. 



Mr. M. N. De, Sericultural Assistant, visited Muktesar 

 in October 1914 to distribute directly from there the uni- 

 voltine mulberry silkworm eggs which had been placed 

 in cold storage during the hot weather. He also went to 

 Calcutta in November 1914 to assist in displaying the silk 

 exhibits sent from Pusa for the Exhibition of Indigenous 

 Products as compared with Enemy Goods. 



The Fieldmen were sent on tour as occasion required 

 throughout the year in connection with outbreaks of pests. 



III. Training. 



No students completed the course in Entomology during 

 the year but two were received from the Punjab in June 

 1915. G. D. Ojha and Harihar Prasad, Entomological 

 Fieldmen at Pusa, were also given some special training. 

 The short courses in Lac and Sericulture only attracted 

 four students, a number much below the average; the 

 Banswara State, Central India, sent one man for the Lac 

 course in June 1915, one student completed a course in Eri 

 and Mulberry Silk and two Sericultural students remained 

 under training at the close of the year. The reduction in 

 numbers of the short-course students seems to be directly 

 due to the publication of popular Bulletins on the culture 

 of lac and silk, although it may be noted that mere book- 

 instruction cannot take the place of practical work. 



IV. Crop Pest and other investigations. 



1. Cotton Pests. Experiments, which are still in pro- 

 gress, were made to test the relative immunity of different 

 varieties of cotton to attacks of bollworm (Earias). A large 

 number of sowings were made of numerous cottons from the 

 United Provinces, the Punjab, the Central Provinces and
