"Lookout, Fred!"
"What is it?"
"A snake!"
"Where?"
"Over yonder! And he is coming for us!"
Sam was right; it was a snake—an angry-looking reptile all of six feet long, and as thick as Sam's wrist. It hissed savagely as it advanced, first upon Sam and then upon Fred.
If there was one thing which could fill Fred Garrison full of terror it was a snake, and the yell he gave would have outmatched that of an Indian on the warpath.
"Save me!" he screamed. "Don't let him touch me!"
"Jump back!" cried Sam, and leaped himself. Then, seeing a tall rock handy, he sprang upon it, and here Fred joined him.
Now, it happened that the snake had its home under the rock, and the movement of the lads made it more angry than ever. With a fierce hiss it came for the rock and disappeared underneath, out of the range of their vision.
"It's gone under the rock!" panted Fred. He was so agitated he could scarcely speak.
"I know it," returned Sam. "I wonder if it means to crawl up here?"
"Oh, don't say that, Sam. I—I—can't we hit it with something?"
