Excerpt: Every winter the reindeer came to the wooded hills where the Cave-men lived. No matter how deep the snow, they always found food. Sometimes they stretched their slender necks and ate moss from the trees. Again they scraped up the snow with their forefeet and found dry grass. The reindeer liked cold weather. They liked the north wind that brought the snow. As soon as the snow began to melt, they started toward the mountains. In the high valleys among the mountains, there was snow all the year round. One morning the Cave-men awoke and found the south wind blowing. All the people were glad; for they knew it would drive the winter away. The reindeer sniffed the warm wind and knew it was time to go. Each leader signalled to his herd. And soon the wooded hills were dotted with small herds moving toward the ford. Straightshaft saw what the reindeer were doing and he signalled the news to the men. Then the Cave-men gathered around Scarface, who was to lead them in the hunt.
