At the first outbreak Derrick and his companions started to run for their lives down the gangway, but as they reached the door of the Mollies' meeting-room the torrent was upon them. They had barely time to spring inside the door and close it as the mad waters swept past. The door offered but a momentary protection, but ere it had been crushed in they were climbing the old air-shaft towards the upper level. It was a desperate undertaking, for the few timber braces left by those who had cut the shaft were so far apart that often they had to dig little holes for their hands and feet in the coal of the sides, and thus work their way slowly and painfully upward. It was their only chance, and they knew it, for they could hear the detached bits of falling coal and rock splash into the water as it rose in the shaft behind them. Finally they reached the top. As they drew themselves wearily, with almost the last of their strength, over the edge, and lay on the floor of the gangway, they were filled with new terror at seeing the light from their lamps reflected in the black waters apparently but a few feet below them. The water was evidently rising into the upper level, and before long their present place of refuge would be flooded. Urged by this peril, they made all possible speed down the gangway into the new workings at the foot of the slope, where they were confronted by a scene of the greatest confusion. The gangways, headings, chambers, and breasts of the lower vein were already full of the turbid flood, and the few miners who had been at work down there had barely escaped with their lives into the level above. Now the water was rising so rapidly that it was evident the upper level would also be flooded in a few minutes. In the great chamber at the bottom of the slope that led to the upper world and safety, miners were flocking from all parts of the workings. Some were trying to drive frightened mules up the travelling-road; others were throwing movable property into cars to be drawn up the slope, and others still were crowding into the same cars, that they too might reach a place of safety. The two men who were with Derrick ran to one of these cars, calling on him to follow them. It was already so crowded that they could not wedge themselves into it, so they clung on behind, and were thus dragged up the slope. That Derrick did not follow them was because he thought of Paul Evert. Poor little lame Paul! where was he amid all this danger and confusion? Had he already got out of the mine, or was he still at his station back in the dark gangway, unmindful of danger? Perhaps somebody had seen him. Derrick shouted, "Where is Paul Evert? Has anybody seen him?" The answer came in the voice of one of the mule-boys. "Yes, I seed him, 'bout five minutes ago, when I run out de las' load. He ain't come out yet." Could Derrick leave him down there, to take his chances of getting out or drowning, while he sought safety for himself?
