76 REPORT OF THE AGRICULTURAL RESEARCH 



East Indian Railway school at Jharipani was subjected to 

 hydrocyanic acid fumigation on account of a plague of 

 bugs, and the result appears to have been satisfactory. 



As Secretary of the Entomological Sub-Committee 

 appointed by the Malaria Conference in Bombay, I assisted 

 in drawing up a scheme for organising work in pathologi- 

 cal entomology. 



A hand-book dealing with methods of drawing and re- 

 producing illustrations for scientific papers has been passed 

 for publication. 



Programme of work for 1912-13. 



The programme for the ensuing year will be subject to 

 modification in accordance with any special requirements on 

 the medical and veterinary side : Directors of Agriculture 

 are being circularized in order that we may ascertain 

 whether with respect to the latter there are any particular 

 directions in which investigation is required. The special 

 lines of work suggested by the Medical Department are 

 mosquito bionomics and the breeding-habits of sandflies ; 

 both of these will be continued, and will in all probability 

 form the major part of "medical" investigations; the 

 former subject alone is one to which several years of work 

 might be devoted. It is suggested that an appeal should be 

 circulated throughout the country to enlist helpers and 

 stimulate interest in medical entomology, and that specimens 

 and information received should be dealt with either at Pusa 

 or Kasauli ; details of the arrangements are still under con- 

 Bideration, but at least some part of the work in this con- 

 nexion would be done at Pusa. 



Identification of specimens and any other work that 

 may be required in connexion with the '' Stegomyia- survey'' 

 will be undertaken, and more detailed observations of 

 these mosquitos will be carried on. Experiments on 

 methods of checking their increase have been begun at 

 Pusa, and will continue until the onset of the cold weather. 



An attempt will be made to elucidate the nature of the 

 influence of citronella oil on fruit-flies : some unexpected
