" Fountains.—Fountains should be licensed and periodically inspected
" and owners should be required to keep them stocked with fish, of
" a suitable species, or to completely empty them and dry them out at
" fixed intervals. Failing this they should be filled up and turned into
" flower beds.
" Garden Tanks.—Garden tanks should be licensed and either stocked
"with a sufficient number of suitable fish or completely emptied and dried
" out at fixed intervals. Failing this they should be filled up.
" Garden Tubs.— Garden tubs should be licensed. They should not
" be fixed or sunk in the earth and they should be provided with a suitable
" cover. Failure to keep them free of mosquito larvae should entail the
" cancelling of the license and their removal.
" (s) Breeding Places of special character—Reservoirs, etc.—The
"reservoirs and filter-beds with their cushion-wells at Malabar Hill and
"Bhandárwáda (Mazagaon), which have been shewn to be dangerous
" permanent breeding places for malaria-carrying mosquitoes, require
" special measures of control. At Malabar Hill all the filter-beds and the
"reservoirs are roofed over, but many sky-lights, ventilators and doors exist
" through which mosquitoes can pass in and out. Every ventilator and
"opening in the roof must be protected by galvanized-iron gauze, and if
"necessary double doors must be provided to prevent mosquitoes entering
" and escaping through the door-ways.
" (t) At Bhandárwáda it will probably be necessary to cover the
" filter-beds and protect every opening with wire gauze.
" (u) Foreshore Pools.—Foreshore pools exist at Colaba and Malabar
" Hill. For dealing with the foreshore pools at Colaba and Walkeshvar
" reclamation will prove effective, and in both cases it is probable that the
" value of the reclaimed land would amply repay the cost of the work.
" (v) Breeding Places in the New Dock-works.—Very large numbers
"of temporary breeding places of dangerous anopheles (N. stephensi)
" were found in the new dock-works during the monsoon, in the form
" of surface pools of rain water. The most important breeding places
" did not appear to be the actual excavations, but pools on the upper surface
"of the works—formed in hollows in the ground. These could mostly be
" levelled off or filled up before the onset of the monsoon of 1910 without
" unduly interfering with the construction work, and purely destructive
" measures by the use of larvacides should not be relied upon except as a
" last resource. For pools in the actual excavations the use of larvacides
" is the only measure that can be adopted and this must be persevered in
" until the completion of the work renders it unnecessary.

Hospital, Government Dockyard, etc.
" (w) At different times of the year breeding places for malaria-
" carrying mosqitoes were discovered on all the above premises. These
" yards, in common with other large yards and compounds, require properly
" draining and levelling; and until this is done they will probably be a
" source of danger.
" (x) Hollows and Undrained Spaces.—There are many hollows and
"open spaces in the north of the island which have little influence upon
" malaria and do not require either draining or filling in at present on
"that account. But a number of observations have shewn that large
" yards and compounds, open spaces and vacant building plots, when
Note.—The kind of fish specially recommended for wells, tanks and fountains is one
locally known as " Piku." It can be obtained at Marol. It may be suggested that the
Municipality should make arrangements to place fish of this kind in any well, fountain or tank
in which the water is sufficiently pure for these fish to live, on the owner of the same making
application. If necessary a nominal charge might be made for the fish. Anabas scandens is
another fish that may be used for placing in wells and fountains, etc. It is known locally as
" Kazari."
