And then the black lamb started to run. And suddenly Snowball whisked about and followed him.

Johnnie Green wondered what had come over Snowball. Was this the pet that had once followed him all the way to school?

"I'll keep him tied up in the barn for a few days—once I catch him," thought Johnnie. If he intended to teach circus tricks to Snowball he certainly didn't want to spend valuable time chasing him all around the pasture.

At last Johnnie Green had Snowball cornered. At last he slipped a rope about Snowball's neck. And then he led his pet towards the bars.

"Baa-a-a!" called the black lamb.

It sounded so much like a jeer that Johnnie turned around and made a face at the black rascal.

In the barnyard Johnnie brought forth a paper-covered hoop. He held it up in front of Snowball. "Jump!" he cried.

But Snowball drew back.

"Baa-a-a!" he bleated. "How do I know that there isn't a tiger behind that thing?"

"Come!" Johnnie urged him. "Jump! Jump!"
