Meantime the flies buzz round the manure pile. The worse it smells the better they like it. They are there for business. Eggs, thousands upon thousands of tiny flies' eggs, are deposited by industrious and prolific flies. A fly's egg! The hired man will laugh at you for bothering over a thing so insignificant. But when his wife comes down with typhoid and the flies come in and worry her, he will complain of his luck and drive out the flies, which go merrily forth to start little private epidemics all over the neighbourhood. Destroy their breeding places. That is one remedy for flies. Trap them, poison them, discourage them. Is it worth while for you to do this when the rest of the people do not? Yes, indeed. If you have very near neighbours, their flies may get to you to some extent, but with nothing to furnish breeding places, and no foul-smelling swill or decaying animal or vegetable stuff around, they will not be attracted to your place. Awaken the neighbour's interest in your "fly-destroying crusade." If you can reach results best by forming a club, organize and pass resolutions and wake people up to their responsibilities. This is practical work for a boys' good citizenship club. TRAPPING I know a city boy who is fortunate enough to have a farm home to go to as soon as school closes in the summer. With his parents and brothers and sisters he lives the life of the farm boy, with enough of gardening, a little of chicken raising, one cow to milk, and a chance to measure his cunning against that of many "varmints" which would otherwise destroy his garden and steal his chickens. He knows how to use a gun, and when, and where. He can make a good trap, a scientific and humane trap, and he knows the ways of the two-or four-or six-footed enemies he is at war with. Between them and him there is a fair field and no favours, just as between one wild creature and another. If to-day he outwits a crow, to-morrow a skunk pays the crow's score with heavy interest by making a meal of a nestful of young chickens. This boy has learned enough of the art of preparing skins to make those he gets salable, and he exhibits with just pride a handsome fur skating cap made by his mother out of skins of mink he has taken. His traps add something every year to his growing college fund. [Illustration: Simple box-trap] There are a great many things about the business of trapping that seem very horrible and brutal to a sensitive person. Because many cruel men have gone into that life, which is a life of the greatest hardship and has little in it to encourage gentleness, we have rather taken it for granted that all trapping is unjustifiable and that a boy who wants to set traps is an inhuman monster and not to be tolerated in a civilized home. If fathers and mothers were all like my young friend's parents, they would see that trapping ought to be a part of a boy's training, just like using an axe, or a saw, or a gun.
