"Now, let me get him—please?" cried another voice, and Jed Burr, the bully, who had apologized that morning, sprang forward and went back again into the building which it was feared would fall at any moment.

"I can't let him do that!" murmured the principal. "I must go after both of them."

But before he could do this Jed came out again, carrying fat little Johnnie Jones in his arms.

"I got him all right!" shouted the former bully.

"You're a brave boy!" cried Mr. Tetlow.

Just then the janitor of the school came up out of the basement.

"It's all right!" he cried, through a white cloud of steam. "I have fixed it! I'll tell you all how it happened."

"Is the earthquake over?" asked Sammy.

"It wasn't an earthquake," said Mr. Hobb, the janitor. "Come here, and I'll tell you about it."
