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 roller skate, he always whistled. The more he worked the louder he whistled.
"What are you going to make now?" asked Sue.
"Oh, I'm not going zactly to make anything," Bunny explained. "I'm just going to do something. I'm going to open one of these windows so we can get out, same as the dog did."
"But he didn't get out of a window," objected Sue. "How could he, if they were nailed shut before we came in? And they must 'a' been, 'cause we didn't hear Mr. Foswick hammering."
"Yes, I guess the windows have been nailed shut maybe a long time," agreed Bunny. "But, anyhow, the dog got out and we can get out."
"But how could he get out if both doors are locked and the windows nailed shut?" Sue wanted to know.
Bunny could not answer that. Besides, he had other things to look after. He wanted to get himself and his sister out of the carpenter shop before Sue began to cry. Bunny didn't like crying girls, even his sister, though he felt sorry for them.
"I can take a hammer and pull the nails out of a window where it's nailed shut, and then I can raise it and we can crawl out," explained Bunny to his sister. "There's sure to be a hammer in a carpenter shop."
There were, several of them, lying around on the benches and sawhorses that seemed to fill the place. There were other tools, also; sharp chisels and planes, but Bunny and Sue knew enough not to touch these. The children might have been cut if they had handled the sharp tools. Mr. Brown kept sharp tools at his dock for mending old boats and making new ones, so Bunny and his sister knew something about carpentry.
"I guess this hammer will be a good one," said Bunny, picking up one with a claw on the end for pulling out nails. He had often seen Bunker Blue at the boat dock use just such a hammer as this.
