"Dunno. I'm crack sure, however, that this stone was not square down the other day. The flat of it was down and the point of it up. Now it's reversed. Besides, here are crowbar marks."

"It'll be hard enough to get out—much harder than it would 'a' been if it hadn't been touched."

"Must have been a strong chap that turned it!"

"Strong? No one man could ever have done it! It would be difficult for two. Why, that stone's not a pound less than four hundredweight!"

"It won't do," said Sandy after a while; "we're gettin' no forrader."

"I suggest," interposed Neville, "that you widen the cracks."

"How can we do that?"
