THINGS TO THINK ABOUT Where do hogs live to-day? How are they taken care of? How do you think the wild hogs found food? Do you think the Tree-dwellers could learn anything by watching the wild hogs? What have you learned from animals? What the Wild Hogs Did for Sharptooth The sun had now been up for some time. Sharptooth was getting hungry. She picked a handful of wild plums from the thicket, but she wanted something more. She kept on down the hill. The wild hogs were rooting under the oak trees. She wondered what they found there, so she stepped near enough to see. They were eating something round and black. She watched them for a long time. As soon as they started off toward the marsh, Sharptooth ran down to the trees. She saw the loose earth that the hogs had rooted up. Then she began to dig where it had not been loosened. She had nothing to dig with except her hands, but she was not afraid to dig with them. She soon felt something that was round and hard. She dug it up and looked at it. It was a truffle. It was black and warty on the outside. She bit off a piece. It was white inside. She tasted it and found that it was good, so she dug another and ate it. She wondered how the wild hogs knew that the truffles were there. Perhaps you can tell. Perhaps you have heard stories of how hogs dig truffles in France to-day. THINGS TO DO 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?
