"That's all right," answered Dick, "but we can't stand here all day figuring out precautions. We've got to know right off whether there's anyone in that chamber watching the boys!"

"What a joke it would be to put on a ghost in Tunnel Six!" laughed Will in a decidedly cheerful frame of mind now that rescue seemed so near.

"Don't try any foolishness!" advised Canfield. "Let's rescue the boys if possible and make our way out of this horrible place."

Will crawled to the edge of the shaft with Dick and whispered as he lowered him into the dark opening below:

"Remember, that Ventner may have discovered the money. If so, we must secure it before we leave the place! It will be just like him, to stow the bank notes away in some chamber like the one you are about to enter. When you strike bottom, if there is no one in sight except the boys, turn on your searchlight and take a good look over the interior of the chamber.

"We were in there not so very long ago, but at that time we weren't thinking of making a search there for hidden money. You'll have to use your own judgment about turning on the light, of course. The outlaws may be out in the gangway, some distance from the entrance to the chamber, or they may be within six feet of where the boys are held as prisoners."

"Tommy ought to be able to tell me the minute I strike the heap of shale whether the outlaws are close by or not!" Dick suggested.

"Of course!" answered Will, "if he knows. If the men are not in sight, and he doesn't know where they are, you'll simply have to take chances. If you get caught in there, you'll have to shoot, and shoot quick!"

Dick dropped down into the old shaft and directly the anxious watchers above heard the rattle of shale as it dropped from the pyramid under the opening. Will, still clinging to the rope, lay on his stomach and peered downward, watching with all anxiety for some show of light, or some sound which might indicate the situation below.

Directly Will felt a soft, steady pull at the rope, and knew that one of the boys was ready to be hoisted to the top.
