What did they use instead of a needle? What kind of thread did they have?
“Greybeard asked Fleetfoot to drop the hot stones in the water again.”
How the Cave-men Protected Themselves from the Cold
One morning Fleetfoot started out of the cave, but a cold wind drove him back. Snow had fallen during the night, and the air had grown very cold. It was not fit for a bare-backed boy to go out on such a day. So Fleetfoot stayed in the cave all day long.
All the Cave-men stayed in the cave nearly all the day. Once Chipper went out and found fresh tracks. He followed the tracks until he came within close range of a reindeer. But his bare arms shook with the cold, and he missed his aim.
The next day was bitterly cold. The river was frozen almost into silence. Only the ripples of the swiftest currents laughed aloud at the frost. The snow was deep on the hillsides. It was deeper in the valleys, and the narrow ravines were almost filled with snow.
The third day was still very cold and everybody was hungry and cross. The children were crying for food, and since Antler had nothing to give them, she was trying to get them to play.
