“I’m going to help, also,” said Tommy.

“No, you stay here,” commanded Jerry. “Bob can go if he wants to.”

Bob joined Ned. They ran to the stream and had filled the pails when, just as they started on the way back, the wounded cougars, driven from the camp, came dashing after the boys.

“Now we’re in for it!” exclaimed Ned. “Run, Bob!”

And run they did, as they had never run before, and left the beasts behind.

“Have you the water?” asked Jerry eagerly as the boys came in.

“We have!” exclaimed Bob. “And hard enough work we had getting it.”

“Good!”

Jerry hurriedly poured most of it into the radiator, though every one in the cave looked at the fluid with longing eyes.
