WHY THE FLY MUST DIE.

HUMANITY’S WORST ENEMY. “’File'•■house fly exists only'through the toleration of men—a toleration which, were it not ignorant, would he criminal,” says the “World’s Work.” “The house fly is the most terrible single eriemy that mankind lias among living creatures.” Beasts of the jungle liave/ slain their thousands, but this prowler in the household lias slain his tens of thousands. Of all vermin he is the most filthy; of all purveyors of disease the most deadly. This is not only the opinion of the “World’s Work,” for an eminent authority has issued reports made on the results of experimental tions designed to prove the extent to which infection may be carried by flies', and further observations were recorded on the ways in which artificially infected flies carry and distribute pathogenic and other bacteria. The experiments and observations qudted. in the report show definitely, thaljr artificially infected flics, both house flips and blow (lies, are capable of infecting fluids, such as milk and syrtip, on which they feed, and into width they fall. In the case of the house fly, infected with certain microorganisms, gross infection may be produced in milk, for at least-three days, and/ a smaller degree of infection for ten -days, or even dongcr./. Blow flics produce gross infection for six to nine days with non-sporo-bearing mic-ro-organisms, apd some degree of infection for three or four weeks.
