"Run! Run!" shrieked George, high above the tumult.

For a thrilling instant Ken stood his ground and fired at the bobbing gray backs. But every break made in the ranks by the powerful shells filled in a flash. Before that vicious charge he wavered, then ran as if pursued by demons.

The way was downhill. Ken tripped, fell, rolled over and over, then, still clutching the rifle, rose with a bound and fled. The javelin had gained. They were at his heels. He ran like a deer. Then, seeing a low branch, he leaped for it, grasped it with one hand, and, crooking an elbow round it, swung with the old giant swing.

Before Ken knew how it had happened he was astride a dangerously swaying branch directly over a troop of brownish-gray, sharp-snouted, fiendish-eyed little peccaries.

Some were young and sleek, others were old and rough; some had little yellow teeth or tusks, and all pointed their sharp noses upward, as if expecting him to fall into their very mouths. Feeling safe, once more Ken loaded the rifle and began to kill the biggest, most vicious javelin. When he had killed twelve in twelve shots, he saw that shooting a few would be of no avail. There were hundreds, it seemed, and he had scarcely fifty shells left. Moreover, the rifle-barrel grew so hot that it burnt his hands. Hearing George's yell, he replied, somewhat to his disgust:

"I'm all right, George--only treed. How 're you?"

"Pigs all gone--they chased you--Pepe thinks we can risk running."

"Don't take any chances," Ken yelled, in answer.

"Hi! Hi! What's wrong with you gazabos?" came Hal's yell from down the slope.

"Go back to the boat," shouted Ken.
