WHY THE FLY MUST DIE.

HUMANITY'S WORST ENEMY. "The house fly exists only through the toleration of men—a toleration which, were it not ignorant, would be criminal/' says the World's News. Hie house fly is the most terrible single enemy that mankind has among living creatures. Beasts of the jungle have, slain their thousands, but this piowler of the household has 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 News, for an eminent local authority lias issued reports made on the results of experimental investigations designed to prove the extent to which infection may be carried by flies. Experiments were made to measure the possible range of flight of Hies, and further observations were recorded on the ways in which artificially infected flies carry and distribute pathogenic and other bacteria. The experiments and observations quoted in the report show definitely that artificially infected flies, both house flics and blow-flics, are capable of infecting fluids, such as milk and syrup, on which they feed, and into which 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 longer. Blow-Hies produce gross infection for six to nine days with nonspore-bcaring micro-organisms, and some degree of infection for three or four weeks.
