_Collect five or six vegetables or fruits._ _Blindfold some one and let him smell of one of the vegetables and guess what it is._ _When he guesses right, blindfold some one else._ _When you have a chance, dig a root with your hands, then dig one with a sharp stick._ _Which way is the easier?_ XI. THINGS TO THINK ABOUT Can you think how the wild hogs protected themselves? Do hogs have tusks now? Can you think why the wild hogs were not as fat as our hogs? _How the Wild Hogs Protected their Young_ Sharptooth watched the wild hogs every day. She learned many things from them. They were peaceable creatures when not disturbed. They lived on fruits, wild nuts, and roots. When they had eaten all they wanted, they went down to the river or lake. They hid in the reedy marshes. They hid in the thorny thickets. But they always kept together. Sharptooth watched them from a tree. There were tiny little pigs with long, light stripes. They kept close to their mothers. There were larger pigs that had lost their stripes. They, too, stayed with their mothers. There were wild boars about three years old. [Illustration: "_There were larger pigs that had lost their stripes_"] They did not go far from their mothers. They were not strong enough yet to protect themselves. There were many full-grown hogs. There were fierce boars with long tusks. Sharptooth watched them eating acorns. A pack of hyenas was watching, too. They were hiding in the underbrush. They were lying in wait for the smaller pigs. But the old hogs scented danger. They gathered the little pigs together. The stronger ones stood in a circle around them. Their white tusks glistened in the sunlight. They were ready to fight for their young. The hyenas were afraid. They sneaked away in the underbrush. The little pigs were safe. THINGS TO DO _Show how the wild hogs protected the little pigs._ _Show how the hyenas came up and sneaked away._ _Cut some wild hogs from paper._ XII. THINGS TO THINK ABOUT Do you think that the Tree-dwellers had schools? What did their children need to know? How would they teach them? Have you ever seen a cat teaching her kittens? Have you ever tried to teach a baby? What can you teach the baby to do? What do you need to have done for you? What can you do to help yourself? What can you do to help others? _How the Tree-dwellers Taught their Children_
