ed again coaxingly. But no dog crawled out from
under the shavings, sawdust, or piles of boards.

"Where can he be?" asked Sue.

"I guess he ran out the back door," suggested Bunny.

"Then maybe we can get out there, too!" cried the little girl, and she
and her brother, with the same thought, ran to the rear of the shop.

"Here is the door," said Bunny, as he pointed it out.

It was a large affair that slid back from the middle of the wall to one
corner. It was tight shut.

"And it's locked, too," cried Sue, pointing to a big padlock.

To make sure, her brother tried the padlock. Sure enough, it was locked,
and the key was nowhere in sight.

"I can slide the door a little bit," said Bunny, and by hard work he
managed to move it about an inch. This allowed a little of the breeze
to come into the carpenter shop but that was all.

"We can't get out through that crack," protested Sue, pouting. "Nobody
could. Oh, dear! I don't see why this old carpenter shop has got to have
all the doors locked."

"Hum, that's funny!" said Bunny Brown.

"How do you s'pose that dog got out with both doors locked?" asked Sue
of her brother.

Bunny paused to think. Then an idea came to him.

"He must have jumped out a window, that dog did," he said. "There must
be a window open, and he got out that way. And that's how we can get
out, Sue. We'll crawl out a window just like that dog jumped out. Now
we're all right. Mr. Foswick locked us in his carpenter shop by mistake,
but we can get out a window."

"Oh, yes!" agreed Sue, and she felt happier now.

But again came disappointment. When the children made the rounds of the
shop, looking on both sides, they not only saw that not a window was
open, but when Bunny tried to raise one he could not.

"Are they stuck?" asked Sue.

"No," replied Bunny. "They're nailed shut! Every window in this shop is
nailed shut, Sue, and the doors are both locked!"

"Oh!" exclaimed Sue in a faint voice, and she looked at her brother in a
way he felt sure meant she was going to cry.

CHAPTER III

THE DIAMOND RING

Whistling as cheerfully as he could, Bunny Brown glanced all around the
carpenter shop.

"Are you whistling for the dog?" asked Sue.

"No, not zactly," Bunny answered. "I'm just whistlin' for myself. I'm
going to do something."

"What?" asked Sue.

She knew that whenever Bunny was making anything, such as a boat out of
a piece of wood or a sidewalk scooter from an old ro
