rrow valley close by a deep and hidden ravine. This
was a place where the Cave-men liked to hunt. So they agreed to follow
Scarface through the hidden ravine.

Scarface led the way, and all the men followed. Not a leaf rustled
beneath their tread. Not a twig broke as they crept up the side of the
deep ravine and looked out at the herd.

Everybody wanted to get the yearlings or young cows, for their flesh
was tender and sweet. But the cows and young bison were in the center
of the herd. They were guarded by the sentinels, whose flesh was hard
and tough.

And so the Cave-men wondered how to get a young bison. They wondered
if the vigilant leader was more than a match for them. They watched
his signals, and saw fresh sentinels take the places of the hungry
ones. They noticed how quickly the bison obeyed every signal the
leader gave.

[Illustration: "_With a quick snort he turned and charged._"]

At last the Cave-men decided to attack the leader first. They waited
till he was not more than a stone's throw away. Then Scarface gave the
signal and the men made a bold attack.

Straightshaft hurled his spear with all his might, then turned to give
place to the others. The leader was taken by surprise. The men had
crept up so quietly that not till the spear whizzed through the air
did he suspect danger.

With a quick snort he turned and charged. Straightshaft ran, but the
others met the charge. They hurled their spears and dealt heavy blows
with their stone axes.

Before the leader could give the alarm he lay stretched out on the
ground. The sentinels looked for a signal. Meanwhile the cows and
yearlings tried to make their escape.

Then each of several sentinels tried to lead. But the frightened herd
did not know which one to follow. Some of the bison rushed one way and
some rushed another. Then there was a general stampede. They gored one
another with their sharp horns. They trampled one another under their
feet. They were too frightened to know what they were doing.

It was then that the Cave-men singled out the young bison. When they
had secured them for their prize, they started toward the cave,
singing--

_To-day we went hunting._
_We crept up the ravine;_
_We surprised the leader of the bison._
_He made a charge upon us--_
_We have his horns for a headdress._
_We killed many a young bison;_
_We have plenty of tender meat._

Perhaps one of the sentinels became leader of the her
