I. KEEPING WELL. 1. Why do our bodies need "housecleaning"? How do we get rid of the waste part that is a gas? Of the part that is water? What carries the carbon dioxid to the lungs? What carries the waste water to the sweat tubes and the kidneys? What other waste is there to be gotten rid of? 2. Suppose that you and your chum each have an equal chance to take a bad cold from someone else; your chum catches it, and you don't. What might be one reason why you don't? Place your hand over your liver. How can you keep it in good working order? 3. What is the bladder? Why is it so very necessary to empty the bladder regularly? When you perspire freely, how does that help the kidneys? II. SOME FOES TO FIGHT. 1. You have seen moldy bread? What is, the mold? What makes it spread? 2. Suppose you take some pieces of moldy bread or potato and turn a glass jar or bowl over them. Catch a few flies and put them under the glass, and leave them to crawl over the moldy food. After a day, put the flies under another glass with some pieces of fresh bread or potato. If you find that the fresh food quickly becomes moldy, how will you think that the mold germs came to it? (If you keep the jars in a warm place, the germs will grow faster, and you won't have so long to wait before you can see the mold.) 3. What other kinds of germs do flies carry? How do they carry them? 4. A Board of Health caused a liveryman to be fined because he allowed a manure pile to remain behind his stable. Why was his act a misdemeanor? From what do flies come, and how do they grow? 5. On your way to and from school, what have you noticed that could breed or attract flies? How could these things have been avoided? 6. The next time you go into a butcher shop or grocery store, notice how the things are kept and be ready to tell the class what you think about it. 7. In what ways may germs be carried, besides by flies? 8. What do we mean by the "Great White Plague"? Why is it called this? What are people doing to try to cure it? 9. What can you do to help prevent it? 10. Why ought you to stay away from other people when you have a cold? What do you need most in order to get well? 11. Do you always have your own towel to use? Why should you? 12. Write a little story about the picture on p. 112. III. PROTECTING OUR FRIENDS. 1. Is there a Board of Health in your town? If not, what takes its place? See if you can find out some of the things that the Board or the Officers have done for the town. 2. What do we mean by _quarantine_? What is the _quarantine station_ in ports where passenger steamers land? See if you can find out about any time when a city or port was guarding its people against an infectious disease. 3. Have you been vaccinated? How was it done? Why was it done? How do we all know that it is a very wise thing to have done? 4. How can you help the Health Officers to keep your town a healthful place?
