If nothing disturbs it, the boat of eggs floats on the water a little longer than a day, when all of a sudden the shells of the eggs begin to break and the little "wiggle-tails" hatch, or come out of the shells. These funny little "wiggle-tails" go frisking about in the water. They dive here and there down into the water, hunting for something to eat. These are the baby mosquitoes. They are very queer looking, with their big heads and eyes and a funny little tube at the tail end of their bodies. They push this tube up out of the water to get air to breathe. I saw a number of them push these little tubes up to the top of the water, but, when I got close to them, down to the bottom of the barrel they would dive, head foremost, as if they were scared. They soon had to come up again for another breath of air. Mother said that if no one disturbed them they would eat germs and all sorts of little water plants for about two weeks, growing all the time. At the end of that time, each one would curl himself into a cocoon, like a ball, called a pupa. After about four days of rest and growing in this cocoon, the case would break and out would come a thing with wings, a full-grown mosquito. It would stand on its case or cocoon, dry its wings in the sun, and then fly away to begin life as a mosquito. Mother said she did not want to give the little "wiggle-tails" a chance to become mosquitoes, and that if I would bring her some oil from the kitchen pantry, she would show me how to kill the little "wiggle-tails." I ran for the oil, oil just like that your Mamma burns in her lamps. Mother poured a few spoonfuls in the rain barrel, and that was the end of Mr. Wiggle-tail. The oil kept the "wiggle-tails" from getting any air to breathe through their funny breathing tubes, and they smothered. [Illustration] Mother says we must have a Mosquito Brigade and go about the place killing all the mosquitoes; that we must not let water stand in any tin cans or barrels; and that we must pour oil in the ditches and ponds where water stands and where the mosquitoes can lay eggs. The mosquito will not lay eggs on the dry land, for the "wiggle-tails" cannot take care of themselves on dry land, and the mosquito mothers know this. It seems to me that Dame Nature, as Mother calls her, has taught many wonderful secrets to her children. Mother told me why she wanted to kill all the "wiggle-tails." I will tell you about it to-morrow, if you will come to the grape-vine swing with me. QUESTIONS 1. What did the little boy see in the rain barrel? Why couldn't he catch them? 2. How did the "wiggle-tails" get into the barrel? 3. Why do they have to come to the top of the water so often? 4. Why did the little boy's mother want to destroy or kill the little "wiggle-tails"? 5. What is a Mosquito Brigade? Can't we have one in our school? MALARIA
