All she knew for the first few minutes was merely that there had been an accident to the train, and they were standing still now in the darkness of the tunnel. For some seconds she paused, and gasped hard for breath, and tried in vain to recall her scattered senses. Then slowly she sank back on the seat once more, vaguely conscious that something terrible had happened to the train, but that neither she nor her companion were seriously injured. As she sank back in her place, Cyril Waring bent forward towards her with sympathetic kindliness. "You're not hurt, I hope," he said, holding out one hand to help her rise. "Stand up for a minute, and see if you're anything worse than severely shaken. No? That's right, then! That's well, as far as it goes. But I'm afraid the nervous shock must have been very rough on you." Elma stood tip, with tears gathering fast in her eyes. She'd have given the world to be able to cry now, for the jar had half stunned her and shaken her brain; but before the artist's face she was ashamed to give free play to her feelings. So she only answered, in a careless sort of tone-- "Oh, it's nothing much, I think. My head feels rather queer; but I've no bones broken. A collision, I suppose. Oughtn't we to get out at once and see what's happened to the other people?" Cyril Waring moved hastily to the door, and, letting down the window, tried with a violent effort to turn the handle from the outside. But the door wouldn't open. As often happens in such accidents, the jar had jammed it. He tried the other side, and with some difficulty at last succeeded in forcing it open. Then he descended cautiously on to the six-foot-way, and held out his hand to help Elma from the carriage. It was no collision, he saw at once, but a far more curious and unusual accident. Looking ahead through the tunnel, all was black as night. A dense wall of earth seemed to block and fill in the whole space in front of them. Part of one broken and shattered carriage lay tossed about in wild confusion on the ground close by. Their own had escaped. All the rest was darkness. In a moment, Cyril rightly divined what must have happened to the train. The roof of the tunnel had caved in on top of it. At least one carriage--the one immediately in front of them--had been crushed and shattered by the force of its fall. Their own was the last, and it had been saved as if by a miracle. It lay just outside the scene of the subsidence. One thought rose instinctively at once in the young man's mind. They must first see if any one was injured in the other compartments, or among the debris of the broken carriage; and then they must make for the open mouth of the tunnel, through which the light of day still gleamed bright behind them.
