"To be sure I am," said Twinkle.

"But you don't talk every minute, do you?"

"Mama says I do," she answered.

"But you don't. You're sometimes quiet, aren't you?"

"'Course I am."

"That's the way with me. Sometimes I roll, and so I'm called the Rolling Stone. Sometimes you talk, and so you're the Talking Girl."

"No; I'm Twinkle," she said.

"That doesn't sound like a name," remarked the Stone.

"It's what papa calls me, anyway," explained the girl. Then, thinking she had lingered long enough, she added:

"I'm going up the hill to pick those berries. Since you can roll, suppose you go with me."
