Strangling, sweating, spent, they got to the side wall and raised themselves up, gasping for fresh air. Their senses wavered and swooned in that half-suffocation and slowly they comprehended that they were still alive and that the dust was settling. "Are you all right?" they called to each other in acute unison, their voices betraying a great apprehension, and then, reassured for the instant, they sagged weakly against the walls and each reached out to find the other. Their hands met and clasped fervently and, again in unison, they said, "Thank God!" A match spluttered dimly through the dark and dust-clogged air, a candle slowly took flame and they looked at each other. Bill was leaning against the wall, weakly, and trying to recover his strength. A tattered trousers leg clung above his bared leg and foot where he had wrenched himself loose from the rock, and torn his boot away in so doing. Along the length of the white flesh was a flaring line of red, where the point of rock had cut deeply when he made that last desperate struggle to escape. He dropped to the floor and clutched his wound with his hands while Dick, almost with a moan, thrust his candlestick into a timber and savagely tore his shirt off and rent it into strips. He stooped over and with hasty skill bandaged the wound. "It's not bad, I hope," he said, "but it does hurt, doesn't it, old partner?" "That's nothin'," bravely drawled the giant, striving to force a grin to his pain-drawn lips. "Don't worry now, boy! Think what might have happened if I'd been there a minute or two longer, or if I couldn't have got loose at all!" In their thankfulness for the last escape they had almost forgotten the fact that their situation was still almost hopeless, and that perhaps the speedy end would have been preferable to one more agonizing, more slow, to come. They got to their feet at last and hobbled forward, the big man resting half his weight on his friend's shoulder and making slow progress. Again they were centered on the faint hope that beyond was some sort of opening, because now they knew but too well that their retreat was effectually cut off. If there was no opening ahead they were doomed. They consulted the plan again and went forward. Abruptly they came to a halt, shutting their jaws hard. They had come to the end of the main drift and it was a blank wall of solid stone where the prospectors had finished! "Well, old man, there's still the two side drifts to examine," said Bill with a plain attempt to appear hopeful that did not in the least deceive the other. "Yes. That's back there about fifty feet," Dick assented, finding that it required an effort to steady his voice. "The other one is behind that barrier."
