SUMMER NUMBER Pigs’ 
fish are furnished a supply of small fish (“Shiners’’) preferred 
by them, as a food, to the top minnows. Many forms of aquatic 
animals subsist on the water plants left, and help greatly in 
keeping our minnow eating fish away from the top minnow. 
The top minnow being too numerous to obtain sufficient food 
near the shore, and being but little bothered by the larger fish, 
spreads over the surface, and naturally eats many more young 
mosquitoes. ; 
Notwithstanding the tremendous superiority of this over 
the older methods, relatively small numbers of mosquitoes reach 
the final or winged stage of life. These then attempt to per- 
petuate their species. As said before, they must have a blood 
meal and protection from light and wind. These we have done 
our best to place beyond their reach. However, trees, grass, 
wild and domestic animals, will always be here. So we have 
tried to make his hiding places not only scarce but disagree- 
able, and even dangerous. Frogs and toads search out and eat 
mosquqitoes, on the banks of ponds, streams, and in inland 
grass. Protected from man, owls, hawks, and snakes, they have 
multiplied so that one has to watch one’s step. The hornless 
chameleon has the same enemies and performs the same func- 
tion in bushes, trees, under uneven logs, etc. Spiders are encour- 
aged in dark corners, hollow trees, etc. We soon had as many of 
all of these as we needed without resorting to breeding. The 
small tree frog, however, not only hunts mosquitoes, but is very 
useful in fruit and citrus trees as a destroyer of certain insect 
pests. It was found that a small box of hardware cloth placed 
over these tadpoles in a puddle allowed an unusual number of 
them to reach maturity. Hunted even by chickens, small tin 
tobacco boxes attached to trees make them excellent citadels. 
What few mosquitoes escape all of this and start to fly are 
confronted by an unusual number of insectivorus birds. Bird 
houses for their young, the killing of their enemies, and the 
abolition of the “sport” of killing them has been all that was 
necessary in this respect. 
These frogs, birds, etc., form an excellent outside “screen’’, 
far preferable to the old method of placing domestic animals 
between the house and the pond, in the pious hope that the 
mosquito would obtain her blood meal from the poor beasts. 
The object of my screen is to prevent the mosquito getting her 
“blood meal’, not to furnish her one.
