“Well, half of him is. What are you doing with my half?” asked Sue. “Course you can do what you like with your half,” she went on. “But you can’t hurt my half.”

“We’re not going to hurt Toby,” Bunny explained.

“We’re just going to do a new trick with him and Patter,” added Charlie.

“Oh, if it’s a trick, all right,” assented Sue.

Toby stood still, except for the switching of his tail to drive away flies, until Bunny and the boys had him hitched to the cart. And twice, while this was going on, Patter leaped up on Toby’s back and sat there.

“You mustn’t do that, Patter!” cried Bunny, calling his dog down. “We don’t want you to do that trick now. Wait a minute.”

And when Patter jumped up again Sue laughed and said:

“I guess I’d better hold him for you. As long as Toby is here, Patter will think you want him up on his back. I’ll hold the dog.”

When George saw how quickly Patter obeyed Sue, the older boy had an idea.

“I think I know how we can teach Patter to pull on the right rein or the left rein to guide Toby,” he said.
