"Give us a rest!" cried Ken, in disgust.

The boat moved as if instinct with life. It dipped, then--wheeze! it dove over the bench. Hal was thrown off his feet, fell back on the gunwale, and thence into the snaky moss. George went sprawling face downward into the slimy ooze, and Ken was jerked clear off the bench into the stream. He got his footing and stood firm in water to his waist, and he had the bow-rope coiled round his hands.

"Help! Help!" he yelled, as he felt the dragging weight too much for him.

If Ken retarded the progress of the boat at all, it was not much. George saw his distress and the danger menacing the boat, and he leaped valiantly forward. As he dashed down a slippery slant his feet flew up higher than where his head had been; he actually turned over in the air, and fell with a great sop.

Hal had been trying to reach Ken, but here he stopped and roared with laughter.

Despite Ken's anger and fear of snakes, and his greater fear for the boat, he likewise had to let out a peal of laughter. That tumble of George's was great. Then Ken's footing gave way and he went down. His mouth filled with nasty water, nearly strangling him. He was almost blinded, too. His arms seemed to be wrenched out of their sockets, and he felt himself bumping over moss-covered rocks as soft as cushions. Slimy ropes or roots of vegetation, that felt like snakes, brushed his face and made him cold and sick. It was impossible to hold the boat any longer. He lodged against a stone, and the swift water forced him upon it. Blinking and coughing, he stuck fast.

Ken saw the boat headed like a dart for the rock where Pepe stood.

"Let 'er go!" yelled Ken. "Don't try to stop her. Pepe, you'll be smashed!"

Pepe acted like a man determined to make up for past cowardice. He made a great show of brave intentions. He was not afraid of a boat. He braced himself and reached out with his brawny arms. Ken feared for the obstinate native's life, for the boat moved with remarkable velocity.

At the last second Pepe's courage vanished. He turned tail to get out of the way. But he slipped. The boat shot toward him and the blunt stern struck him with a dull thud. Pepe sailed into the air, over the rock, and went down cleaving the water.
