Show FLIGHT OF THE THEp p FLY FLYBY I IBY BY FREDRIC J HASKIN The fight on the house bouse fly that Is now being made in the various cities of the e country haa hs h brought brou ht about a complete revolution n of sentiment as to that mace insect When science came to look carefully Into In his habits Mr dr Fly was found not to be bethe uv the Inoffensive sort of citizen clUsen be he had al at always always ways been regarded It had long lon been known that be was bothersome out but ut he 0 was found to be a villain of the deepest dye killing more people every ever year than lire are fie killed by all the murderers in the world He has been ben given a new name since his true character has haa come to light a name which brands him wherever h he goes the typhoid fly y Dr L 1 0 O Howard Hord the United States entomologist has selected that name for him He agrees that the term is la a little harsh as aa there are other causes of typhoid and says YI that manure fly y would fit him rather better since his favorite breeding place olace is Ie in horse manure But for tor pub public public lic he use Dr Howard Hoard thinks typhoid fly Cly Clyla is la the best t name The evidence against the fly y Is 18 com corn complete complete plots and convincing in Many a murderer murde fi has gone to the gallows on weaker Not NotIons ot long loft ago 0 flies files were caught cau ht in differ different different ent cot parts of the country and they car carried carried ried tied an of a million and a quarter germs to the fly y It may be said by b the skeptic that the fly y Is so small aman he cannot carry filth But If If anyone will look at him through a microscope the error of such suh a conclusion wilt will ill be clearly seen en Under the microscope he be becomes becomes comes the most mOlt fuzzy fuu creature alive hairy from tip Up to toe and terribly in indifferent Indifferent indIfferent different about keeping clean These Theae flies were caught in sterilized nets so MJ that none of the germs found could be laid to the account of the net Then each fly was WAa placed In a separate bottle which had been sterilized sterilised and filled tilled with a Ii known quantity of sterilized water The fly was allowed to swim around until exhausted and then a drop of the water was placed under unde a Ii micro microscope microscope scope and the germs germ counted A careful record of each eath fly fI y was kept and aDd the germs germa found on each were found to range from G to tIO The next fly fl that falls fans into the readers coffee roffee or his milk may leave six million germs in the cup The house houle fly is thoroughly omnivorous He will eat anything that he comes come across and the more filth there thre Is the better it suits sulta him hem Breeding In manure by preference he spends a fLir share of or his ht living days In such surroundings He flies met direct from the manure heaps to our houses and onto our food whenever opportunity presents Itself and Is 18 always laden with ith microscopic particles of filth and disease Here again has ha Mr Fly been caught with the roods goods on him himas himas himas as the police pollee say In the army camps during the war it was found that the flies mes which swarmed about the latrines would come directly to the mess tents the white lime being plainly visible on their feet In New N w York filth was dyed with th red ink and set In the street Flies soon lOOn showed up in the house with red on their feet The most mo t startling and conclusive evi dence that has been brought against a the fly fl Is IB that gathered by Dr Daniel D Jackson In his investigation of the sub lub SL of harbor Pollution at New York With his assistants he went Into the whole question with great thoroughness and Jl his findings are noteworthy He found r that In the neighborhoods of sewer outlets i l the flies files were most moet numerous and that In those same Ame neighborhoods typhoid fever and other intestinal diseases were most moet Prevalent The number of victims of Li these thelle diseases roe roae rose and f fell with the coming and passing of the fly y tribe Dully Daily ex examInations of c captured tur f flies mes were made and millions of germs were found In some ln Instances the thc mea flies were carefully washed d end and 1 completely cleansed of germs They Thy were then released and al lowed to swarm over Zer ln Infected I material In the laboratory They collected as many germs the second and third time thus as they did the first in one Instance a hundred thousand typhoid fever germs germ were found on a single fly In New York there are more re than deaths deatha from typhoid and oth t r diseases during the fly season It Is es that were the fly effectually ban It would result In ln the saving of i s lives a year in that city and the theOf prevention Of SaMO OOOO cases ca e of f sickness Typhoid fever feer Is estimated by experts to toi cause an annual economic loss amount Ing i to In the United States and fully in Canada It is also figured that the American American people spend a year for door dOOl and window screens Not only is the fly a of typhoid but he likewise communicates communicates tuberculosis by carrying it from the sputum of tubercular patients to oth ers and carries carnes every form of Intestinal d disease Se I It ls is said w that much of the cholera the most fatal of or chil drens dl dIseases eue la is carried to the little victims by the flies files It has hall been found In studying the life history of the fly that the female lays S an average avera e of eggs e g during her life time and that in favorable localities there are twelve generations of them In a sin single gle season f One writer n has s figured floured from this that the progeny of a single pair pall of flies files which survived the winter would amount to several everal sextillions But when It is remembered that thaI one sextillion Is Isone Isone isone one thousand million trillion It will ap pear that he i h ha has overshot the mark If It every egg hatched and every female fly y lived to lay 1 eggs the result would be le Just Juet about what was estimated But figuring gurin that only fifty females would hatch from the eggs of each fly fb the there result re would still reach the ln able total of quintillion flies fUet How Il It is III that even such figures obtain ie is shown when one comes to figure up the bulk that such a num ber her of flies les would make More than MX flies fifes cannot be contained in a cubic Inch of space yet piled that closely clo ely quin quintillion flies les would cover conI square miles of territory one foot thick and the progeny of pairs pai of flies tiles would cover every ever acre of United States terri tern territory territory tory one foot thick But If each female fly fiT brought forth only ten len other female flies les the total progeny of a pair pall of flies file starting at the beginning of the season would be toe over twentysix trillion Even E with ten female flies to each generation the resultant bulk produced by a single pair starting in at the beginning of the season would fill ISO million cubic feet of space the equivalent of the excava excavations excavations excavations at Panama for the best month and anda a half ever put In by the canal diggers Seven different varieties of flies Ies are found in dwelling houses ranging from the one which rejoices in the scientific name of Dome to the plain Bluebottle Iu Domestic stands at atthe atthe atthe the top of the list as out of every hundred flies belong to his fam family famIly ily hr It Is upon him that Dr Howard would forever affix the name hame typhoid fly fh Men read with horror of the ray ravages ages of the tigers

released from the th thrall thralldom ran rail random dom of the mosquito mo and yet conserva consena conservative five tive scientists declare that Domes tica ie is a more deadly enemy of mankind than mosquitoes mo and lions and tigers rs and snakes combined Yet for generations he has been n allowed to dwell in mans own house and when we have screened him out it has been because he was trou tree troublesome troublesome and not because he was w dan dangerous dangerous Toe The microscope was the agency a cJ that revealed his true character That cleanliness s is next to godliness waa was never better exemplified than in the case Calle of the fly He must be born in filth If It the female cannot find manure in which to deposit her eggs eg she singles out the next filthiest place she can find Old rags form a favorable substitute sub for the th stable Waste aste paper constitutes another Incubator But it is always necessary that the eggs egge be he laid In filth of some character It is ls believed by the authorities authorities ties on the subject that If approximate cleanliness reigned everywhere the fly I iy pest would disappear This Thia Is Ie proved b by experience In the mountains of Vir Virginia Virginia Virginia I ginia there is a little summer resort around which are built some thirty cot cottages cottages cottages It Is ii I a deserted village from Sep September to June not a soul living there during those theM months When the cottage owners move in In June there is not a fly to be seen save the few that follow the horses of the cottagers up the moun mountain mountain tain tam side for two miles mUes But they never become numerous until more than six weeks after the fly season son reaches its height in the Shenandoah valley below The first arrivals of the next summer find no flies there all those of ot the ibe previous summer eummer having perished in the cold and for lack of filth The fly nuisance in the country is fa a far harder one to handle than that in the I cities dUes since the farmer fanner with a dozen head of horses thirty or forty fort cattle i and sheep and hogs in proportion can cannot cannot I Inot not have the sanitary conditions
