Perhaps she was some desert woman, the widow of some miner who had been shot as these three had tried to shoot him and Barney Oakes. Mean, malevolent as they were, they would still lack the brutishness necessary to shoot an old woman. So they had shut her up there in the rock hut, not daring to take her back to civilization where she would tell of the crime. It was all plain enough to Casey. The story of the crippled miner made him curl his lip contemptuously when his back was safely turned from Joe.
That day Casey thought much of the old woman in the hut, and of Paw's worse than inferior cooking. Though he did not realize the change in himself, six months of close companionship with the Little Woman had changed Casey Ryan considerably. Time was when even his soft-heartedness would not have impelled him to patient scheming that he might help an old woman whose sole claim upon his sympathy consisted of four rock walls and a look of calm despair in her eyes. Now, Casey was thinking and planning for the old woman more than for himself.
Wherefore, Casey chose the time when he was "putting in an upper" (which is miner's parlance for drilling a hole in the upper face of the tunnel). He gritted his teeth when he swung back the single-jack and landed a glancing blow on the knuckles of his left hand instead of the drill end. No man save Casey Ryan or a surgeon could have told positively whether the metacarpal bones were broken or whether the hand was merely skinned and bruised.
Joe came up, regarded the bleeding hand sourly, led Casey out to the dugout and bandaged the hand for him. There would be no more tunnel work for Casey until the hand had healed; that was accepted without comment.
That night Casey proved to Paw that, with one hand in a sling much resembling Joe's, he could nevertheless cook a meal that made eating a pleasure to look forward to. After that the old woman in the little stone hut had pudding, sometimes, and cake made without eggs, and pie; and the potatoes were mashed or baked instead of plain boiled. Casey had the satisfaction of seeing the dishes return empty to the dugout, and know that he was permitted to add something to her comfort and well-being. The Little Woman would be glad of that, Casey thought with a glow. She might never hear of it, but Casey liked to feel that he was doing something that would please the Little Woman.
For the first few days after Casey was installed as cook, one of the three remained always with him, making it plain that he was under guard. Two were always busy elsewhere. Casey saw that he was expected to believe that they were at work in the tunnel, driving it in to a certain contact of which they spoke frequently and at length.
At supper they would mention their footage for that day's work, and Casey would hide a grin of derision. Casey knew rock as he knew bacon and beans and his sour-dough can. To make the footage they claimed to be making in that tunnel, they would need to shoot twice a day, with a round of, say, five holes to a shot.
As a matter of fact, two holes a day, one shot at noon and one at night, were the most Casey ever heard fired in the tunnel or elsewhere about the mine. But he did not tell them any of the things he thought; not even Joe, who had intelligence far above Paw and Hank, ever guessed that Casey listened every day for their shots and could tell, almost to an inch what progress they were actually making in the tunnel. Nor did he guess that Casey Ryan with his mouth shut was more unsafe than "giant powder" laid out in the sun until it sweated destruction.
Persistent effort, directed by an idea based solely upon an abstract theory, must be driven by a trained intelligence. In this case the abstract theory that every prisoner must be watched must support itself unaided by Casey's behavior. Not even Joe's intelligence was trained to a degree where the theory in itself was sufficient to hold him to the continuous effort of watching Casey.
Wherefore Paw, Hank and Joe presently slipped into the habit of leaving Casey alone for an hour or so; being careful to keep the guns out of his reach, and returning to the dugout at unexpected intervals to make sure that all was well.
