A Living Tomb.

Literally buried alive, as Walt Wilder had said, were he and his companion.

They now understood what had caused the strange noise that mystified them—the rumbling followed by a crash. No accidental débâcle or falling of a portion of the cliff, as they had been half supposing; but a deed of atrocious design—a huge rock rolled by the united strength of the savages, until it rested over the orifice of the shaft, completely coping and closing it.

It may have been done without any certain knowledge of their being inside—only to make things sure. It mattered not to the two men thus cruelly enclosed, for they knew that in any case there was no hope of their being rescued from what they believed to be a living tomb.

That it was such neither could doubt. The guide, gifted with herculean strength, had tried to move the stone on discovering how it lay. With his feet firmly planted in the projections below, and his shoulder to the rock above, he had given a heave that would have lifted a loaded waggon from its wheels.

The stone did not budge with all this exertion. There was not so much as motion. He might as successfully have made trial to move a mountain from its base. He did not try again. He remembered the rock itself. He had noticed it while they were searching for a place to conceal themselves, and had been struck with its immense size. No one man could have stirred it from its place. It must have taken at least twenty Indians. No matter how many, they had succeeded in their design, and their victims were now helplessly enclosed in the dark catacomb—slowly, despairingly to perish.

“All up wi’ us, I reck’n,” said the guide, as he once more let himself down upon the ledge to communicate the particulars to his companion.

Hamersley ascended to see for himself. They could only go one at a time. He examined the edge of the orifice where the rock rested upon it. He could only do so by the touch. Not a ray of light came in on any side, and groping round and round he could detect neither crevice nor void. There were weeds and grass, still warm and smouldering, the débris of what had been set on fire for their fumigation. The rock rested on a bedding of these; hence the exact fit, closing every crack and crevice.

On completing his exploration Hamersley returned to his companion below.

“Hopeless!” murmured Wilder, despondingly.

“No, Walt; I don’t think so yet.”

The Kentuckian, though young, was a man of remarkable intelligence as well as courage. It needed these qualities to be a prairie merchant—one who commanded a caravan. Wilder knew him to be possessed of them—in the last of them equalling himself, in the first far exceeding him.

“You think thar’s a chance for us to get out o’ hyar?” he said, interrogatively.

“I think there is, and a likely one.”

“Good! What leads ye to think so, Frank?”

“Reach me my bowie. It’s behind you there in the cave.”

Wilder did as requested.

“It will depend a good deal upon what sort of rock this is around us. It isn’t flint, anyhow. I take it to be either lime or sandstone. If so, we needn’t stay here much longer than it would be safe to go out again among those bloodthirsty savages.”

“How do you mean, Frank? Darn me if I yet understan ye.”

“It’s very simple, Walt. If this cliff rock be only sandstone, or some other substance equally soft, we may cut our way out—under the big stone.”

“Ah! I didn’t think o’ thet. Thar’s good sense in what ye say.”

“It has a softish feel,” said the Kentuckian, as he drew his hand across one of the projecting points. “I wish I only had two inches of a candle. However, I think I can make my exploration in the dark.”

There was a short moment of silence, after which was heard a clinking sound, as of a knife blade being repeatedly struck against a stone. It was Hamersley, with his bowie, chipping off a piece from the rock that projected from the side of the shaft.

The sound was pleasant to the Kentuckian’s ear, for it was not the hard metallic ring given out by quartz or granite. On the contrary, the steel struck against it with a dull, dead echo, and he could feel that the point of the knife easily impinged upon it.

“Sandstone,” he said; “or something that’ll serve our purpose equally as well. Yes, Walt, there’s a good chance for us to get out of this ugly prison; so keep up your heart, comrade. It may cost us a couple of days’ quarrying. Perhaps all the better for that; the Indians are pretty sure to keep about the waggons for a day or so. They’ll find enough there to amuse them. Our work will depend a good deal on what sort of a stone they’ve rolled over the hole. You remember what size the boulder was?”

“’Twas a largish pebble; looked to me at least ten feet every way. It sort o’ serprised me how the skunks ked a budged it. I reck’n ’twar on a coggle, an’ rolled eezy. It must ha’ tuk the hul clanjamfry o’ them.”

“If we only knew the right edge to begin at. For that we must go by guess-work. Well, we mustn’t lose time, but set about our stone-cutting at once. Every hour will be taking the strength out of us. I only came down for the bowie to make a beginning. I’ll make trial at it first, and then we can take............
