"Oh, please don't swell up and bust!" begged the little rabbit. "Mother says if you swallow a cork it will swell and swell inside you until you can't stand it any longer."

"What's that?" asked the little chipmunk. "Did I swallow a cork?"

"Yes, you did," sobbed Little Jack Rabbit. "And it's all my fault. I let it drop into your mouth by mistake. Of course, you didn't see it. How could you, with your eyes shut?"

Chippy Chipmunk was now thoroughly frightened. "You've murdered me, that's what you've done, Little Jack Rabbit. Oh, what shall I do?"

Just then who should come along but Dr. Heron. He had very long legs and a very long bill. All doctors have very long bills, otherwise it wouldn't pay to be a doctor.

"What's the trouble?" he asked, opening his little black bag. "Anybody sick?"

"I'm going to be," cried Chippy Chipmunk. "Oh, dear Dr. Heron, don't let me die! Please don't!"

"Stuff and nonsense! Don't talk like that!" said the big bird doctor. "Put out your tongue."

"Can you see the cork?" asked Little Jack Rabbit. The little chipmunk was just going to ask the same question, but Dr. Heron had hold of his tongue, so he couldn't.

"See what?" asked the doctor. "What are you talking about?"
