As the typhoid germs are very often distributed in this way, Dr. Howard has suggested that the house-fly shall be known in the future as the typhoid-fly, not because it is solely responsible for the spread of typhoid, but because it is such an important factor in it and is so dangerous from every point of view.
It was of a brownish colour with three yellow bars across the body, and scarcely larger than a common house-fly. We soon saw others buzzing about in considerable numbers. I asked Jan what he meant. "Das de tsetse: when bite horse or ox den dey die," he answered.
But a careful examination of the offender, in such instances, will show that it was not a house-fly but probably a stable-fly, which does have mouth-parts fitted for piercing. Three of these veins end rather close together just before the tip of the wing, the posterior one of the group being bent forward rather sharply a short distance from the tip.
Poole wrote a brief pamphlet upon the house-fly and the dangers of that pest, and this was printed and scattered broadcast about the town. To the amazement of a good many of the older members, like Elder Concannon, Mr.
For the fact is that the feet and proboscis of the common house-fly are covered with microbes of all sorts, picked up by his explorations upon every kind of filth. At every step which he takes he plants a few dozen microbes, which include those of infantile diarrhoea, typhoid, and other prevalent diseases.
The ground, bestrewn with leaves and dried wood, is a mass of large flies rather like our common house-fly, but both butterflies and beetles seem scarce; and I confess I do not feel up to hunting much after yesterday's work, and deem it advisable to rest.
The house-fly drives back the loathsome flesh-fly or blue-bottle, to the salvation of blankets and fresh meat. The Briton of the south has indeed taken with him all that he could of the old country. The berries were poisonous enough to kill an imported elephant on one occasion. He has also brought a few things which he wishes he had left behind.
All that is left of them is a dry skin which tears from end to end, half uncovering a Fly-pupa. A few days later, the parasite emerges. It is a small, greyish Fly, fiercely bristling with sparse hairs, half the size of the House-fly, whom it resembles slightly. It belongs to the Tachina group, who, in their larval form, so often inhabit the bodies of caterpillars.
The microscope reveals as much in one direction as the telescope in another, and the common house-fly seems in size midway in animal life." "And do you believe that the Divine hand is employed in forming such trifles as these?" "The Divine will is. But these trifles make the avalanche and the winter's protection for next year's harvest."
There were no insects, except one kind of fly about one-fourth the size of the common house-fly. It bit cruelly, and was much more tormenting than the mosquito on the sea-coast. This seems to be the native country of the arrowroot. Wherever you passed through a patch of wood in a low situation, there you found it growing luxuriantly.
