SUMMER NUMBER 35 
Again careful examination of the most likely places along the 
lake shores revealed only schools of minnows and other natural 
enemies and no mosquito larvae. A boat drawn up to the shore 
with some water in it showed one or two rafts of eggs and a 
few young wrigglers. If left a few weeks it might become a 
breeding place. 
I might give many more illustrations that prove the same 
point. Of course being a stranger and spending, usually, only 
one day in a place, it was impossible to make a systematic ex- 
amination of all the backyards, henyards and barnyards of a 
town; but I have found in most towns the water barrels on the 
freight platforms breeding enough mosquitoes to make life a 
burden to the entire community. 
Bringing the matter home to us here, mosquitoes, both 
Anopheles and Culex, are now numerous on the University 
campus. A recent survey, while not as yet complete, certainly 
adds evidence to support the position above advanced. At the 
meter box north of Buckman Hall, where the water mains come 
in from West University Avenue, both Anopheles and Culex 
larvae were found in considerable numbers. Many more of both 
kinds are breeding in the stagnant water that has collected in the 
bottom of the swimming pool. Culex in great numbers were 
found in the water pans in the poultry yard back of the kitchen. 
A few Culex were found in a trash can at the barracks. Culex 
by thousands were found in a barrel of fertilizer water back of 
the Experiment Station barn and also in a barrel half full of 
water near the mule stable. Considerable numbers were breed- 
ing in the watering tubs at the dairy and especially, as most of 
the faucets are dripping continually, in the pools that form on 
the ground around them. The cement watering troughs and 
wallowing basins in the hog yards close by contained numbers of 
wrigglers. On the other hand the three sinks, the small stream 
in the kitchen garden, and the effluent from the septic tank were 
all examined and no mosquitoes discovered in them. My obser- 
vations coincide, in the main, with those reported by Loftin in 
recent numbers of THE FLORIDA BUGGIST, although he does record 
finding a few mosquito larvae in “marshes”, “ditches” and 
“sphagnum swamps” where the moss and weeds form wet masses 
too dense for top minnows to penetrate. And I do not wish to 
be understood as meaning that mosquitoes do not commonly breed 
in natural as distinguished from artificial waters. I have many 
times found them breeding in numbers in the mountain bogs of
