Cook Young (Major A. W.) • The Prevalence of Flies in Delhi and their 

 reduction. — Proc. Third All-India Sanitary Conf., Lucknow,

The prevalence of flies in Delhi is a very marked feature in the 

 insanitary condition of the city and it has been necessary to organise 

 a campaign against them. More efficient removal of filth and refuse 

 apparently had very little effect. Old heaps of rubbish were burned 

 and the number of dumping grounds reduced. On the top of new 

 rubbish not less than one foot of earth was deposited and it was 

 found that where this was done the flies ceased to breed, especially 

 when a system of trenching was used and the earth, well rammed on 

 the top. Nevertheless the nuisance was not very materially dim- 

 inished and it was not until house to house inspection and individual 

 cleansing and disinfection was thoroughly carried out that the plague 

 was diminished. Stables and cow-sheds, which are very numerous 

 in the city, were found to be the chief breeding places and these were 

 specially dealt with. Manure for garden or agricultural purposes 

 was not allowed to be stacked in any compound for more than 4 days. 

 It was then directed to be dug into the ground and to be covered with 

 not less than 1 foot of earth. 



Food shops of all kinds were also greatly infested and provision of 

 proper dust-bins and thorough inspection and cleansing proved useful. 

 As the result of these and other measures, the reduction of flies has 

 been steady, with the exception of one or two breaks. The first of 

 these corresponded with the cessation of rain for about 10 days in 

 June and the second from 15th to 25th October. This corresponds 

 with the Dewali festival which is the " annual spring cleaning " of 

 all the Hindoo houses in the city and an outbreak which occurred 

 about 10 days later would seem to indicate that the flies had hatched 

 out from eggs deposited in the rubbish cleared out of the houses during 

 that festival. The result of the campaign has so far been satisfactory, 

 but improved methods and still greater strictness in carrying out the 

 administrative measures required are strongly urged.

Malaria is endemic in Goa. In Nova-Goa, the commonest mosquito 

 is Anopheles {Nyssomyzomyia) rossi ; Anopheles (Neocellia) stephensi 

 occurs, but is rare. There are large numbers of Stegomyia, Culex 

 fatigans, impellens and cynereus [sic].
