| your ITlenuS. II you nave IL ana want
 to fill up some of your pet enemies all you have to do is to train a few Ano-
 phe%s and set them to work. Let them
 bite you first and then the people you

 complish your hearts desire,
 There are two ways to distinguish be-
 tween the active but innocuous CuleX
 and the accursed Anopheles. Culex has
 a -pronged proboscis, Anopheles has
 three prongs.
 If you let one of the beasts get near
 enough to you to permit such close
 inspection that may be a good way to
 determine whether you are going to get malaria as result of your carelessness
 or merely q mosquito bite. But there
 is better way, which will enable you
 to determine before the assailant gets
 in her proboscis.
 CuleX is hangdog cuss and in any
 situation, flying, walking or biting, his head and beak make an angle with his body. Anopheles, on the other hand, is
 very straightforward business-like | individual. In any situation his head
 and beak and body form one straight line.
 Therefore, if you see mosquitoes ad-
 vancing upon you in a straight line,
 get up and flee, for they are the fore runners of malarlla
 The entomologists say that the life
 history of a mosquito occupies about
 two weeks. It is fairly active life.
 Most persons will be unwilling to be-
 lieve that the business of the mos
 quito is anything else save biting poor | l11of fnr nrt toc bO oet hut the investigations of the scientific gen. tlemen show that the little pests are really tremendously busy in reproduc- ton.
 A female lays from two to four hun | dred eggs at once. MT. Lutz takes 200 as the basis of his calculation Say half of them die the first brood gives hun dred insects, of which half are female.
 On the average, six broods are brought forth in a season. These fifty fine, young mosquitoes of the first brood of the season, give the world in a short time some 5000 more, fair-sized num- Der of grandchildren even for a selfre- specting mosquito.
 Still they are not numerous enough to make much trouble if they confined themselves to the amusement of hunt ing human beings. But before the per- sons they have bitten have begun to recover from the effect of the bites the biters will have produced third brood of some 100000,
 Now, MT. Lutz supposes, for some reason, that half o fthese meet an early but timely death. The other half, how ever, are still 125, ,00l strong, and produce fourth brood of 900. By the same figuring the next brood numbers 31, 250, 000000 and the grand total for the six broods of descendants of one mos quito in one season is mere trifIe of 1SS 755, 100
 MT. Lutz relates the fact that a Min nesota investigator once filtered the water in a rainwater barrel and found thirtyfiVe grammes of young mos quitoes each gramme numbering, by actual count 217, or 7,595 mosquitoes for the barrel.
 Besides, there were thirty-two egg masses, averaging 302 eggs, or 9664 more. Another similar test showed up 19,110 mosquitoes in one barrel Tn his inspection of the north district MT. Lutz found at house in Cold Springs nine rain-water barrels.
 there lS OLltllr Ht SdNS, lllbIG lIcli one barrel at house, or a cistern many times larger than barrel, and often tubs, buckets and tin cans. In Cold | Spring there were more than fifty bar rels, in Oyster Bay 15O. in Locust Val | ley forty and in Bayville over thirty.
 "A little arithmetic will show the | necessity of careful watching on the | part of every householder. and in the | absence of this a movement on the part , of the community to force those without public spirit to do their duty. For if 1 an intelligent community attends to it's | rain barrels as it should one careless not to use a stronger adjective-house- holder, could, by retaining his pet [ hatchery bestow upon his fellow creatures the almost unthinkahle gift of at least tO8,000 full-fedged mos quitoes every season.
 Our friend, who had nine barrels | furnished the village of Cold Spring with ten million or more mosquitoes during the long season of 1901.
 When I examined the premises of one strong believer in the south side idea l found two ain-barrels, two tubs for dogs, two unused cisterns, both alive, and numerous cans and buckets all wrong side up.
 This is a reference to the old notion ] that the north shore suffered from mos quitoes that were blown over from the | south shore of Long Island by the pre- valng southery winds The work of the entomologists, however, has shown that mosquitoes do not travel far from the place where they breed, and thus the south side idea has been exploded"
 It is established beyond dispute that breed only in water, and chiefly in stagnant or slowly moving fresh or brackish water They never breed in the air or in bushes or in damp places, as Is commonly supposed. They rarely breed in salt water, and therefore salt marshes where the tide flows strongly are not dangerous. But salt marshes where pools are left by the high monthly tides which become are among the most produc- live sources of mosquitoes The favor- te breeding place of Anopheles is the clear water of sluggish streams and pools, or even springs
 It was with a full understanding of Ill these facts about mosquitoes and heir life and habits that the expert trt ffsAtn 41AA
