“Help! Help!” shouted a voice. “Help! I’ve got the snakes, but I’m caught and they may get away! Help!”
“The professor!” shouted Ned.
“And a snake has him!” added Bob.
“It can’t be,” declared Harvey Brill. “The luminous snakes are only little things. They couldn’t hurt a cat.”
But again came the cry:
“Help! Help! Help me save the luminous snakes!”
“He must have ’em!” declared Jim Nestor.
