Jack decided that he would eat half of the sandwich that day and reserve the rest for the second one. His cigars were precious luxuries to be indulged in once every twenty-four hours after he had knocked off work. He attacked the cave-in with the cool energy that characterized him. Out of a piece of board he fashioned a kind of shovel with his knife. Bits of broken timbering lay at the foot of the shaft. These he dragged into the tunnel for fuel to feed a small fire which he built to give light for the work. All through the night and till noon the following day he dug among the fallen rocks and dirt, cleaning this _débris_ away after he had loosened it with his bare hands. The impact of the fall when he had been thrown down the shaft had jarred him greatly. With the slightest movement of the body his back and shoulders ached, sending shoots of pain in protest to his brain. The sprained ankle he had bound tightly in a wet handkerchief, but every time his weight rested on that leg he had to grit his teeth. But it was not in him to quit. He stuck to his job till he had done the shift set himself. At noon he crawled back to the foot of the shaft. He was fagged to exhaustion. For half an hour he lay stretched on his back with every muscle relaxed. Presently he cut from his coat the pocket that contained the sandwich and divided the mash of ham and bread into two parts. One of these he ate. The other he returned to the coat. Favoring his ricked ankle as best he could, Jack climbed the wall ladder to the ledge upon which he had found himself lying the previous night. Five minutes' examination of the walls showed him that there was no chance to reach the top of the shaft unaided. He tested the jammed timbers to make sure they were secure before he put his weight upon them. During the next six hours he called aloud every few minutes to attract the attention of anyone who might chance to be passing near. Toward evening he treated himself to his first cigar, making the most of the comfort that it gave him. When the stub grew short he held it on the small blade of his knife so as not to miss a puff. What was left he wrapped in a pocket handkerchief for later use. As the stars began to come out in the little patch of blue sky he could see just above his prison Jack lowered himself again to the foot of the shaft. Here he lay down a second time and within five minutes had fallen into a deep sleep.
