" and Victoria Docks, Carnac Bunder and areas north of the Port Trust
" Dispensary between Manson and Frere Roads, has shown the existence of
" numerous potential breeding places for mosquitoes. In some cases larvae
"of Anopheles stephensi have been found recently, and I have been
"informed that they were prevalent in many places within this area during
" last monsoon. But such potential breeding places, numerous as they
" appear to be, and requiring the most careful attention and control, sink
" into insignificance beside the condition of things prevalent within the
" New Dock enclosure. Within this area,, especially upon the land occupied
"by the stone heaps, etc , lying between the Frere Road and the New Dock
" wall, there are countless puddles and pools of water formed by the recent
" heavy rain. It is quite impossible to give even a partial estimate of the
" number or area of such breeding places as already exist, but it may be
" stated that practically every shallow collection of water on the upper
" level of the works, except such as have been treated with Pesterine,
" contain numerous larvae of anopheles—90 per cent. of which are those
"of N. stephensi. At the present time it appears to me probable that
"there are more mosquitoes of this variety breeding within the New
" Deck area than in the whole of the other parts of Wards A. and B. put
"together, excluding perhaps Fort North section with its innumerable
"wells, A recent examination of the blood of 0:3 persons resident within
" the New Deck enclosure has shown that, out of the 46 adults and 17
" children from whom the blood was taken, 44 or nearly 70 per cent. har-
" boured malaria parasites. This is the highest proportion yet found in
" any community in Bombay. These observations serve to show that it is
" necessary to adopt organized and systematic measures for the control
" and suppression of anopheles breeding grounds if the incidence of
" malaria is to be diminished within this area, and the neighbourhood.
" The question is of such immense importance to the City and Port of
" Bombay that in my opinion the measures to be adopted should be
" as follows.
" For New DOCK Enclosure.—A whole time European Inspector should
" be appointed whose sole duty must be the supervision of anti-mosquito
" work. It is quite impossible for a man to properly control the innumer-
" able breeding places which already exist if he has other duties to perform
"in addition. The responsible officer should have a sufficient stall at his
"disposal including men trained to find mosquito larvae. It is probable
" that many of the email pools could be easily drained or levelled, but others
"must be systematically treated with Pesterine or crude petroleum. For
"this purpose suitable sprayers must be provided—preferably of the knapsack
"type, the Success Sprayer made by the Deeming Manufacturing Com-
" pany of Salem, U. S. A,, gives satisfactory results. The inspector must
"systematically patrol the whole area, carefully examining each likely
"breeding place, assisted by trained men. (The services of trained men
"can be obtained by application to the Municipal Commissioner who
" has the names of nine such men who are available for immediate
" employment.) It is essential that whoever be appointed to superintend
" such work must be made clearly to understand that his sole responsi-
" bility is the prevention of mosquitoes breeding in the area within
" his control. Failure to carry out such work should entail liability
" to dismissal.
" Quinine distribution.—In addition to mosquito destruction I think
" it will be necessary to employ a compounder to distribute quinine in a
" palatable form (sugar-coated tablets) daily from house to house, among
" the residents within the Dock enclosure. Already there is a very large
" amount of malaria present among these people and situated as they are in
" the immediate neighbourhood of numberless Anopheles breeding grounds,
" they are a menace to the health of the shipping and the population
" in the City.
"For Old "Dock Area.—In regard to the Old Deck Area, I consider
" that as there are so many potential breeding grounds within this area it is
