VIEWS 01? AN EXPERT. . Tho übiquitous fly comes in for a good deal of opprobrium us a distributor of disease genus, but a now aspect of his achievements in that direction is brought out in an article ou "the House Ply as a Crop-wrecker," in tho "Technical World" magazine. Tho Muscidae, or house flics, and tho Snrcophagidao or carrion Hies aro the culprits, 'i'hey cany on their tuet, and in tho matter they deposit thu germs which produce blights and rots both fungoid and bacterial. An expert on plants «iys that a lly-speck ou a window pane can be seen to have "thread-like rays growing out from it; this is generally duo to the growth of fungi. If a little bluo mould from cheese or bread ho put into a bottle of sweetened water together with a lly, tlie ily will drink of the water, and wilt leave specks ou tho glass: these specks in a moist atmosphere at living-room temperature will blossom out in 18 hours to a luxuriant growth of bluo . mould. The writer gives many instances of plant diseases which lie attributes to this cause, and concludes that wo must fight it by preventing tho breeding of flics.
