The herd plunged too, for reindeer know it is best to follow their leader. The reindeer swam through the deep water and waded out to the opposite bank. Then the frightened creatures hurried on toward the well-known ford. [Illustration: "_The reindeer swam through the deep water and waded out to the opposite bank._"] "Why did the reindeer jump into the river?" asked Fleetfoot of Chew-chew. Before she could answer Eagle-eye pointed to a big cave-bear. The cave-bear was going into a thicket when Fleetfoot heard his mother say, "Cave-bears and hyenas hide in the thickets. They lie in wait for the herds." Scarface seemed to be lying in wait on some rocks by an evergreen tree. He had stopped on his way to the reindeer pass to see what had frightened the herd. While the men were going to the pass, the reindeer were gathering at the ford. Several herds of two or three hundred each were already there. Other herds were coming. The flat sandy banks on one side of the river were already covered with reindeer. Soon the ford was filled, and the reindeer began to press up the narrow river valley. When at last all the herds from the wooded hills were gathered at the ford, the handsomest leader of all stepped forth to lead the way. After looking around to see if an enemy was near, he started up the well-trodden trail through the narrow river valley. Slowly the great herd began to move. To those watching from the cliff, it looked like a moving forest. Those in advance were soon out of sight, and were going toward the pass. Meanwhile the men had reached the pass where the bravest ones hid at the farther end. There they waited to spear the reindeer, while others hid behind rocks near the entrance to drive the reindeer on. While the women and children watched from the cliff a signal came from the men. It was a call for the women to come and carry the reindeer to the cave. The younger women went, but Chew-chew stayed and watched with the children. At length the Cave-men returned. The men brought trophies and the women brought heavy loads of meat. They found Chew-chew and the children still watching from the cliff. There they all watched for a long, long time; for not until the sun was low down in the sky had the last of the reindeer left the ford. #THINGS TO DO# _Model a large river valley with many little valleys in it. Show where the small herds were. Model the cliffs along the river and show the flat sandy banks on one side, and the narrow valley with steep sides on the other._ _Find rocks and make the reindeer pass. Make the trail from the ford through the narrow valley to the pass._ _Play the story this lesson tells._
