He took the lantern and examined his bunk closely. But nothing was wrong, and after a while he followed the others and laid down again.

Harry and Joe waited a reasonable length of time, and then Harry crawled forth to adjust the rope and threads once more. Again the rope slid over Fred’s face, and once more he set up a howl.

“It’s a snake! I felt it again!” he yelled. “He’s right here in the bunk!”

“Step on him!” cried old Runnell, and got his gun a second time.

Harry tried to jerk the rope away, but before he could do so Fred came down on it with his bare foot. Then the threads broke, and the rope remained on the floor in front of the bunk, while Fred leaped away, as if he had stepped on a hot plate.

Lantern in one hand and gun in the other, Joel Runnell ran to kill the snake. But when he saw the object on the floor he gave a loud laugh.

“Call that a snake,” he roared. “It’s only a bit of rope.”

“A—a rope?” repeated Fred. He bent forward. “Well, I never!” Then he caught sight of the broken threads, and like a flash realized the joke that had been played on him. “Oh, you—you rascals!” he cried, and catching up the rope, he went first for Harry, and then Joe, and belabored them soundly. Both were laughing, and this made Fred really angry.

“All right, laugh all you please!” he burst out, suddenly. “It was a mean thing to do. To-morrow I’m going to leave you and go home.”

And then, without a word more, he retired for the night.
