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

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?
