the cistern). The sanitary authorities summon householders for not 
having- the cisterns screened, but too often is it the case that :n a 
month or so afterwards the screen is taken off or propped up. 
It is the custom of the householder to store his empty bottles in 
the yard. These are usually laid on the side and piled tip at such 
angle that rain water is collected and another ideal breeding-place 
for the mosquito is provided. Empty tin cans, buckets, earthenware 
pots, etc., adorn the backyard, nearly all being so placed as collect 
water. Very often these are only cleared away after an inspection 
has been made by the authorities, to be followed shortly by another 
collection of useless rubbish. 
Barrels for rain-water are unscreened or covered with a loose- 
fitting top which more often than not is left off. Gutter and gutter 
pipes may be broken or blocked. All these, if defective, collect water 
and facilitate the propagation of the mosquito. Empty tins, 
bottles, even old baths, are often stored under the flooring and, when 
the floors are washed, water will drip through the cracks in the flooring 
and collect in the cans, etc. The usual method of washing a onc- 
storied house is to throw a couple of bucketsful of water on the floor 
and then rub the boards with brooms and sluice on more water. We 
have seen the workmen, during building operations, too lazy to clear 
away the old tin cans and similar rubbish on the ground before nailing 
down the floor. (One house badly infested with mosquitos was a 
source of much worry to us until we took up a few boards and found 
some old saucepans partially filled with water and teeming with larvae.)
