The Acid Test

He held out a silver dollar and dropped it. From the time the coin took to strike Jack judged he was a hundred feet from the bottom.

The flare of a second match showed him a wall ladder leading down, but unfortunately it did not extend above him except in rotting fragments. What had happened he could guess. Supposing him to be dead, his enemies had dropped the body down this deserted shaft. Not for a moment did he doubt who they were. The voices had been unmistakably Cornish, and even without that evidence he would have guessed Peale and his partner as the guilty ones.

Since he could not go up he went down, moving warily so as not to jar loose the timbers upon which he lay. Every rung of the ladder he tested with great care before he put his weight upon it. Each step of the journey down sent a throb of pain from the ricked ankle, even though he rested his weight on his hands while he lowered himself. From the last rung--it was by actual count the one hundred forty-third--he stepped to the ground.

Another match showed him a drift running from the foot of the shaft. Along this he dragged himself slowly, uncertain of direction but determined to find out what possibility of escape his prison offered. For two hundred yards the tunnel led forward and brought him up sharply at an impasse. A cave-in blocked farther advance.
