While they rocked the babies in their cradles they sang them little lullabies. THINGS TO DO _Make some playthings for a baby that you know._ _See if you can make a skin cradle for your doll._ XIII THINGS TO THINK ABOUT How do you think the Cave-men spent the winter? What kind of food do you think they ate? What do you eat in the winter? Why could not the Cave-men have as many kinds of food as you have? Do you think you could stand it to go out in the cold dressed as the Cave-men were dressed? _How the Cave-men Spent the Winter_ Perhaps you think that the Cave-men spent a dreary winter. It might be dreary for you if you had to spend it that way. But the Cave-men knew nothing about such homes as we have. They lived in the very best home that anybody had at that time. That is why they were satisfied. When the weather was pleasant they went out to hunt, but they never had to go far. The wild animals were not yet afraid of men, and so they did not try to get away. By using their spears and stone axes, the Cave-men got plenty of meat to eat. But they got so hungry for something green, that they ate the green moss that they found in the stomach of the reindeer. Sometimes they ate the inner bark of trees. Sometimes they found nuts in squirrels’ nests, but most of the food that they ate was meat. In the coldest weather they did not have even meat, for it was not safe to hunt in the biting cold. They stayed in the cave for days at a time without a taste of food. Sometimes they were so hungry that they chewed hard skins, and they even sucked dry bones. But they managed in some way to live through these cold days, until the weather became warmer again. THINGS TO DO _Think of the coldest and stormiest day you have ever seen, and draw a picture showing how it looked._ _Tell a story of what Brighteyes did during a cold day._ _Tell a story of what the Cave-men did one pleasant day in the winter._ XIV THINGS TO THINK ABOUT Have you ever noticed the bark of a birch tree? Do you know what birch bark is used for? Why is birch bark better to make into baskets and boats than the bark of other trees? Can you think of a way of taking birch bark from a tree without splitting the bark? Have you ever seen bark that has been mended? What do you think the Cave-men used birch bark for? Why do you not have the right to peel birch bark from any tree that you see? Are there any birch trees that you do have the right to take bark from? _What the Cave-men Got from the Birch Trees_ When the snow began to melt, the Cave-men were glad; for it was warm enough to leave the cave. They spent their days on the wooded hills where many birch trees grew. All the Cave-men liked to go to these trees. They liked to peel off the silvery white bark that hung from the older trees in strips.
