"There is no possibility of forcing our way in over there yonder," said he to Arthur, pointing towards the lower shaft which was in connection with the upper one, and from which mighty columns of smoke and thick vapour were issuing. "We have not even made the attempt, for no human being could breathe in that infernal steaming cauldron. Hartmann tried it, but when he had gone five or six steps, he was forced to beat a retreat half stifled, and he was just able to drag out Lawrence, who had followed him, but had fallen at the entrance. Our only hope lies in the upper drawing-shaft; perhaps they may have taken refuge there. Set the engines going, we must make the descent that way."

The man in charge of the machinery, to whom these words were addressed, stood by pale and agitated without preparing to obey.

"The engines have refused service for the last hour," he reported in a tone of distress. "I wanted to send word of it, for all the gentlemen were up at the house, but my messenger could not get through on account of the row there was up there, and I thought, at all events, the gang at work could ascend by the lower shaft which remained free. We have been trying hard to work them, but we can't make them move."

"Heavens and earth! that about finishes us," cried the chief-engineer, rushing by into the shed.

"But by the ladder-way?" Arthur turned hastily to the Director. "Cannot we get down there?"

The other shook his head.

"The ladder-way has not been available since the morning. You know, Herr Berkow, Hartmann had all the upper ladders destroyed, so as to prevent the descent at all hazards. He did not succeed; the men went down by the drawing-shaft, and that is the only access left us now to the mine."

Ulric appeared at this moment with Wilms and several of his usual companions.

"Down there it can't be done," cried he to the miners, while he pushed his way through their ranks. "We should sacrifice our lives all for no use, and they are needed just now to help. Perhaps up here it may be possible, we must go down with the drawing-cage."

He was pressing hurriedly on to the engine-shed, when he was suddenly confronted by Arthur Berkow, who looked sternly at him and said in a loud sharp tone:
