Then the two little puppies felt so badly that they just sat there, on the bank of the mud puddle, and howled as loudly as they could.

I suppose you wonder what good their howling did, but I shall tell you.

Back in the kennel Mrs. Gurr, the mother dog, was waiting and wondering why Don and Prince did not come home.

“I saw them go over that way,” spoke Violet, who was nibbling at a bit of puppy cake.

“They were having a race,” said Ruby, who was practicing at trying to catch her tail.

“Oh, such boys!” cried Mrs. Gurr. “I suppose they’ve gone so far away they can’t find their way back. Come, Spot, we’ll go look for them.”

“All right,” said the other brother of Don and Prince. He was called Spot because he had a white spot on him. Otherwise he was all black.

Mrs. Gurr and Spot hurried out of the kennel, and they had not gone very far before they heard a noise.

“What’s that?” asked Spot, standing still and wagging his tail.

“Listen,” said his mother.
