 CANNOT FLY FAR

|
 Mosquitoes usually do not fly far from their breeding places. The mos quitoes that annoy you on a summer evening probably grow in street gutter in front of your house, or in chicken trough in your back yard, or in any standing water not more than one or two blocks away. Occasionally wind will blow them some distance, but this is frequently overestimated. Old tin cans, dishes or broken bottles, troughs, sewer traps when not in use, the tank in the attic, fire buckets, that pitcher full of water in the guest chamber, in fact any vessel of water which IS not changed frequently is capable of rearing mosquitoes.
 HOW LONG THEY LIVE.
 Mosquitoes are rather short lived on the average, though the we'll fed adults may live a whole season or from late summer to the following spring by hibernating under the bark Of an old rotten log or stump, in pile of hay or leaves, or in crevices in buildings. Those that survive the winter lay the eggs for a new horde upon the return of warm weather. As new brood may develop every ten days or two weeks through the sum- mer, one mosquito in April could give rise to more than 20 trillions by the first of August if they should find food enough to survive. This would be enough to weigh II million tons.
 MALARIAL MOSQUITOES.
 A mosquito bite may be more than an annoyance. After biting a person with malaria the mosquito may be- come infected, but the disease does not kill the insect. It will live to bite other people, and after the germs have spread in the mosquitoes body so that the tiny drop of saliva on the lancets in his beak contains the germs, they enter the blood stream of the newly bitten person and cause ma laria. Malaria is a disease of the blood, and no other agency is known to transmit the germs from one per- son to another except a certain kind of mosquito-the Anopheles. Other species of mosquitoes transmit other diseases in the same way, forinstance, yellow fever is transmitted by the Aedes (Stegomyio), and filaria by the CuteT, our most common mosqui- to- Of course there are score of other mosquitoes found here besides these, which Gas far as known) do no more harm than the discomfort caused by their bite They range in size from the gallinipper down to the forms so small that most of our ordi- nary screens will not keep them out. The An0pheIes, or malarial mosquito, is slightly larger than the common Cullen, and by careful observation it may be identified by it's spotted wings and also by the position it assumes while biting or resting on a surface It is not seen much during the day, but flies around after dusk and after dark. Beware of the night fiier in your bed room. It is apt to be the Anopheles.
 CAUSE OF CHILLS
 The chills of malaria are caused by microscopic parasite or germ which attacks the red blood corpuscles and destroys them, at the same time null tiplying and forming spores every few days, which may again attack new blood cells. Many of these spores are destroyed by the white blood cells which are natures weap- ons against the disease. The chill oc- CUTS when these spores are forming and breaking out of the corpuscles, every two days, or three days, accord ing to the variety of malarial para site. Possibly you have learned that if a liberal dose of quinine is taken in time to be in the blood stream when the chill is expected, it serves to de- stroy the parasites before they are able to attack new set of corpuscles.
 When the Anopheles mosquito feeds upon the blood from a malarial person these germs go through a develop ment in the mosquitoes stomach, blood and salivary glands. With the saliva it enters the blood of another person whom the mosquito chances to bite. Recent discoveries indicate that the stable fly carries infantile paralysis in like manner.
 Swamps have no peculiar atmos- phere which causes the inhabitants to get malaria, nor does the water of swamps contain the malarial germs. But in swampy region mosquitoes breed more freely and the malarial mosquitoes are more prevalent. By measures looking toward the destruc- tion of mosquitoes and their breed ing places, swampy lowlands have been made as healthful as any other place. There is no reason why Con way cannot be made both fyless and mosquitoless by the enforcement of few simple sanitary measures.
