"I couldn't unhitch the stone. It is tied fast to a rope."

"You don't say! Eddie, we are going to get it all right."

"It looks so. I'll try it again in a minute. This time I guess I shall be able to unhitch the stone all right."

"Better take down a knife and cut the rope."

"I will if I have to, but it will hamper me. I'd sooner try it the other way first."

Now Ed was not giving out the facts of his discovery straight.

He had not only found one tin case down there, but two.

They were exactly alike, and both had a rope attached to a small ring, the other end being fastened around a stone.

One of these stones the boy had already unhitched.

He knew that he could not successfully handle both cases, although they were by no means bulky.
