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 débris 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.
He peered in hastily at the other three windows. Not a soul in any one of the remaining compartments! It was a very empty train, he had noticed himself, when he had got in at Tilgate; the one solitary occupant of the front compartment of their carriage, a fat old lady with a big black bag, had bundled out at Chetwood. They were alone in the tunnel—at this end of the train at least; their sole duty now was to make haste and save themselves.
He gazed overhead. The tunnel was bricked in with an arch on top. The way through in front was blocked, of course, by the fallen mass of water-logged sandstone. He glanced back towards the open mouth. A curious circumstance, half-way down to the opening, attracted at once his keen and practised eye.
Strange to say, the roof at one spot was not a true arc of a circle. It bulged slightly downwards, in a flattened arch, as if some superincumbent weight were pressing hard upon it. Great heavens, what was this? Another trouble in store! He looked again, still more earnestly, and started with horror.
In the twinkling of an eye, his reason told him, beyond the shadow of a doubt, what was happening at the bulge. A second fall was just about to take place close by them. Clearly there were TWO weak points m the roof of the tunnel. One had already given way in front; the other was on the very eve of giving way behind them. If it fell, they were imprisoned between two impassable walls of sand and earth. Without one instant’s delay, he turned and seized his companion’s hand hastily.
“Quick! quick!” he cried, in a voice of eager warning. “Run, run for your life to the mouth of the tunnel! Here, come! You’ve only just time! It’s going, it’s going!”
But Elma’s feminine instinct worked quicker and truer than even Cyril Waring’s manly reason. She didn’t know why; she couldn’t say how; but in that one indivisible moment of time she had taken in and grasped to the full all the varying terrors of the situation. Instead of running, however, she held back her companion with a nervous force she could never before have imagined herself capable of exerting.
“Stop here,” she cried authoritatively, wrenching his arm in her haste. “If you go you’ll be killed. There’s no time to run past. It’ll be down before you’re there. See, see, it’s falling.”
