"Oh, it's a lovely trick," declared Janet. "I wonder how he learned it?"

"Maybe Uncle Toby or the lady who owned him first taught Snuff to roll on top of a football," Ted answered, while the yellowish brown cat kept on stepping lightly this way and that, making the ball turn over and over. "I guess Trouble left the ball out here in the yard. He was playing with it last. Then Snuff must have come out, and when he saw the ball he remembered that he knew how to do a trick on it. And he got up and did it without anyone telling him."

"Maybe he won't do it any more," suggested Janet.

"We can soon see," Teddy said. "Here, Snuff!" he called to the big, friendly cat. "Come over here," and Teddy whistled as he did for Turnover. Snuff came as he was called, almost as a dog might do, and Turnover, also hearing the whistle by which Teddy summoned him to meals, came running around the corner of the barn.

"No, we haven't anything for you to eat now, pussies," said Ted, with a laugh. "But I'll give you something in a little while if Snuff does the football trick again."

After petting the two cats, and scratching them under their ears, which they seemed to like very much. Teddy held Snuff in his arms, and told Janet to take up the football.

"We'll put it down in front of Snuff and see if he gets up on it," suggested Teddy. And when this was done the big cat from Uncle Toby's jumped out of Ted's arms, and leaped on top of the football, rolling it over and over just like a clown in a circus.

"Oh, it is a trick—a real trick!" cried Janet. "Wouldn't it be great if we could dress Snuff up in a little suit like a clown?"

"Maybe we can," said Teddy. "But it will be hard, as cats don't like to have fixin's on 'em as much as dogs do. I wonder who taught Snuff that trick? I guess it must have been Uncle Toby."

And, some time afterward, the Curlytops learned that it was their father's queer, animal-loving uncle who had taught Snuff to roll around on a football.
