"Yes, an' it'll be a clear case of luck if we strike one. Don't stop to talk now. We must go at full speed while the air is good."

Seizing Fred by the hand, Brace started once more, and for the time being both forgot fatigue in this struggle for life. On with feverish energy they pressed, yet no glimmer of light broke the profound darkness. More than once each fell over the litter of timbers, but only to rise and struggle on again, until finally Brace halted.

"It's no use," he said with a moan. "Each step now is carrying us lower. I remember hearing some of the old hands say the abandoned drifts were a hundred feet or so farther down the hill. We must be considerably below the deepest shaft."

"Have you given up all hope?" Fred asked in a whisper, for while surrounded by the dense blackness the full tones of his voice sounded fearsome.

"Ay, lad, all hope."

"Try once more. There surely is a way out if we could only strike it!"

"We may as well meet the water here. I've been in the mines long enough to know that this runnin' at random is worse than standin' quiet. When a man's time has come there's no use to fight."

Fred could not urge him farther. The numbness of fear was upon him, brought by this sudden surrender of the man whom he had believed would be able to extricate them from the precarious position, and now he thought only of his mother.

How long the two remained there silent and motionless neither ever knew. To Fred it seemed as if hours passed before Brace seized him by the arm as he cried at the full strength of his lungs:

"Hello! Mate! This way!"
