But before he could say any more he heard a loud thumping sound, and Toto knew what that meant.
“Look out! There’s danger!” cried Toto.
CHAPTER IV
TOTO AND THE TRAMPS
Toto, the bustling beaver, ran as fast as he could and took shelter under a big rock that made a place like a little cave on the side of the hill.
“What’s the matter?” asked Don, the dog. “Are you afraid because I told you about the tramps?”
“Oh, no,” answered Toto. “But didn’t you hear that thumping sound just now?”
“Yes, I heard it,” answered Don. “What was it—somebody beating a carpet?”
“I don’t know what a carpet is,” replied Toto. “We don’t have any at our house. But, whatever it is, it wasn’t that. The noise you heard was one of my beaver friends thumping his tail on the ground.”
