Mosquitoes breed in water. The wigglers of the watering trough or rain barrel are young mosquitoes. You can raise your own mosquitoes as well as your own chickens and pigs. A little precaution would save much annoyance. Neighbourhoods should unite to rid themselves of the pest. Boys can do the work required. The school children in Worcester, Mass., wage very effective war against mosquitoes every year under the guidance of their teachers. The saving in cost of netting and wire screens would almost pay the expense of a campaign against mosquitoes and flies. After emptying or covering all the water receptacles on the place, it is well to place a few decoy pails in promising situations. When the mosquitoes have deposited their eggs, tip over the pails and that is the end of that lot. One female can produce four hundred eggs, so you see what a calamity it is for her young to come to maturity, which they may do in eight to ten days. Mosquitoes have their natural enemies. Where areas of water are too large to oil, we should see to it that fish are plentiful, especially goldfish, sunfish, roaches, killies, and minnows. Toads, frogs, and lizards also prey on mosquitoes as do the nymphs of dragon flies and other water insects. Swallows and purple martins catch mosquitoes on the wing. FIGHTING FLIES The house fly is no longer a mere nuisance, but is a menace to health. He is well named the typhoid fly and the filth fly. The boys and girls who help rid their neighbourhood of these disease-carrying pests are real patriots. Flies are not a heaven-sent plague in this day and generation. Flies in the milk, flies in the pantry, flies on the kitchen door, flies buzzing about the table, are the obvious result of carelessness and mismanagement. What is more, the remedies are not hard to apply. The typhoid fly (house fly) breeds in horse manure. The adult fly feeds upon every known variety of filth as well as upon good food, but the undeveloped fly is a footless maggot and it breeds in your own and your neighbour's stable yard. People will go on buying fly paper, fly poison, fly traps, screen doors, and window netting to keep flies out, but the very fly that has visited a typhoid patient to-day may to-morrow leave the imprint of his foul feet on the baby's face, or drown himself, but not his germs, in your gravy. What does your father have a manure pile for? If he is a frugal farmer he expects to put it on his fields when the other work is out of the way, and plough it in. He knows the value of manure on fields. But does he realize that the best time to carry the manure out is while it is new? Every expert will tell him so and why. In the pile by the barn it lies and burns. Have you seen it smoke? Burnt manure is wasted fertilizer. When it rains, the valuable elements needed by the soil leach out and nourish the crop of "jimson weeds" and burdocks that will crowd round the barn yard next year.
