restaurant in the heart of the town a battered sheet iron wash 
tub, evidently used in its last stages as a garbage receptacle. It 
was about half full of filthy water. There were scores of mosquito 
egg-rafts on the surface and the water was alive with larvae and 
pupae. Mosquitoes were numerous, and there were probably 
many other similar breeding places, but enough mosquitoes were 
breeding in that one tub to supply the town. None were found 
breeding in any of the natural waters. 
In Plant City, on the freight station platform, were seven 
barrels of water, all supplied with eggs and alive with wrigglers 
in all stages. They were pouring mosquitoes by the thousands 
into the business center of the city. The septic tank on the out- 
skirts of the city was also found breeding mosquitoes, literally, 
I think, by the millions. This is a problem for the city engineer. 
No breeding whatever was found in ditches or bay heads during 
a number of examinations extending from March through the 
first half of May. 
Dade City furnishes an especially instructive example. Near 
the A. C. L. depot are extensive water-lily ponds that look from 
the distance utterly hopeless. Careful examination, however, 
along their marshy borders, in the worst looking places, revealed 
only top minnows everywhere and no mosquitoes breeding what- 
ever. Mosquitoes were breeding abundantly in tin cans and 
rubbish of a large dump alongside of one of these ponds. 
The worst night I had during the whole year was spent in a 
room of a hotel in Haines City. There were inside screens sup- 
posed to cover the lower half of the windows, but both lower 
sashes were immovably stuck about half way up. This left two 
eracks the width of each window thru which all mosquitoes at- 
tracted to the windows could pour into the room. I spent the 
entire night killing the pests and estimated the casualties roughly 
at between four and five thousand. In the morning I determined 
to find out where those mosquitoes were breeding. Diagonally 
across the street from the hotel was the railroad station and on 
the freight platform, as usual, were barrels of water, five in this 
instance. One of these had oil on it. The other four were 
covered with a solid scum of mosquito eggs and empty pupa cases, 
and hundreds of mosquitoes could be seen in the act of emerging 
from the water. The capacity of one of these barrels, I should 
think, might be 200,000 mosquitoes every ten days. I was told, 
as usual in such cases, that those barrels didn’t amount to any- 
thing compared with the numbers that were breeding in the lake.
