When they used shafts with knobs and large joints, it was easy to keep a firm hold. So the men made shafts with larger knobs and they put girdles around the smooth shafts. [Illustration: _Chipper using a spear-noose._] At their games of throwing spears and javelins, Bighorn was almost sure to win. It was partly because he had large hands and very strong fingers. By bending one finger like a hook and striking the butt of the shaft, he could send a harpoon straight to the mark. Chipper's hands were not very large. His fingers were not so strong as Bighorn's. But Chipper was a bright young man, and he found a way of using a spear-noose so that he could throw as well as Bighorn. The spear-noose was a simple thing. Chipper made it by tying a noose in each end of a cord. When he used it, he slipped one noose around his thumb and the other around one finger. Then he grasped the spear near the butt and slipped the cord around the knob. The spear-noose was a great help to hunters whose hands were not large and strong. Every time the Cave-men made new weapons, they worked very well for a short time. But as soon as the animals learned about them, they became more cunning in getting away. Wild horses kept sentinels on knolls and hilltops so that they could see an enemy from afar. They guarded their herds so carefully that the Cave-men could scarcely get near enough to hit them with their harpoons. And so the Cave-men returned many times bearing no trophies. They returned many times giving no signal for the women to come for fresh meat. #THINGS TO DO# _Take a harpoon and show how the shaft would swing against the feet of an animal that had been hit by the head._ _Make a girdle around a smooth shaft, or make a shaft with a knob or large joint near the butt._ _Make a spear-noose and show how Chipper used it._ _Think of the wild horses during the first few minutes after the men threw their harpoons. See if you can draw a picture of them._ XXIII THINGS TO THINK ABOUT Think of as many hard things as you can that the Cave-men had to do. Why did they have to do these things? What kind of men did the Cave-men have to be? Think of as many ways as you can that the Cave-men would use to teach the boys. What tests do you think they would give the boys? [Illustration: "_And so the Cave-men tested the boys in many different ways._"] _How the Cave-men Tested Fleetfoot and Flaker_ Winters came and went, and Fleetfoot and Flaker grew to be large boys. They watched the men; they heard them talk; they learned what a Cave-man had to do. Greybeard told them stories of brave hunters that lived long ago. He told them about the animals they must learn to hunt. The boys listened to the stories. And they thought there was no animal too fierce for them to fight. They thought there was no river too swift for them to cross. They thought there was no mountain too steep for them to climb.
