"I've got it at last," he said in a tone of triumph.

"Good; let's have a look at it."

"Not when it's loose. Get me some nails and a hammer and a board of some sort."

"Can you hold it all right?"

"Yes, the thing's quite limp; tired out with throttling poor old Peter, I should say."

"And now," said Saunders when he returned with the things, "what are we going to do?"

"Drive a nail through it first, so that it can't get away; then we can take our time over examining it."

"Do it yourself," said Saunders. "I don't mind helping you with guinea-pigs occasionally when there's something to be learned; partly because I don't fear a guinea-pig's revenge. This thing's different."

"All right, you miserable skunk. I won't forget the way you've stood by me."
