the window. He wanted
to see where the heads of the nails were sticking out, so he could slip
the claw of the hammer under them and pull them out by prying on the
handle. Bunny had not only pulled out nails himself before this, but he
had watched his father and Bunker Blue do it.

Bunny Brown also knew how windows were nailed shut. Once the Browns
owned a little cottage on an island in the river. They sometimes spent
their summer vacations in the cottage, and in the fall, when winter was
approaching and the cottage was to be closed, the windows were nailed
shut from the inside.

Once Bunny had helped his father nail the windows shut, and once he had
helped pull the nails out the next summer when the cottage was to be
opened. So Bunny was now looking for the heads of nails in the window of
Mr. Foswick's carpenter shop.

The first window he looked at was so tightly nailed, with all the heads
driven so far into the wood, that Bunny could get the claw of the hammer
under none of them. He made his way along the bench to the next window.
This window was nearer the street.

"Can you open that one?" asked Sue.

"Yes, I guess so!" exclaimed Bunny.

The little boy saw a nail head sticking out. He slipped the claw of the
hammer under it and pressed hard on the handle.

Whether Bunny had not put the claw far enough under the nail, or whether
the head was so small that the claw slipped off, neither of the children
knew. But what happened was that Bunny's hand slipped, the hammer also
slipped away from his grasp, and the next moment, with a crash and
tinkle of glass, the hammer broke through the window and fell outside.

"Oh, Bunny! are you hurt?" cried Sue, for once she had seen her mother
cut her hand trying to open a window that stuck.

"No, I'm not hurt," answered her brother. "But the hammer's gone out."

"You can get another. There's lots here," said Sue.

"But I can't fix the window," said Bunny, rather sadly. "It's all
busted!"

"It wasn't your fault!" said Sue stormily. "Mr. Foswick ought never to
have locked us in, and then you wouldn't have to try to unnail a window
to get out! It's his fault!"

"Maybe it is," said Bunny, leaning forward to look out of the broken
window.

"Don't try to crawl out!" exclaimed Sue. "You might get cut!"

"I'm not going to," said Bunny. "I was just seeing how far it was and
where the hammer went. It's on the grass, and it isn't far out of the
window at all. If we could only c
