Mark clambered painfully up the glistening embankment, hoping to reach the motionless carriages and escape with his object effected before the train he could hear in the distance ground into them with a hideous crash.

He knew his danger, but, to do him justice, he scarcely gave it a thought—any possible suffering seemed as remote and inconsiderable just then as the chance of a broken leg or collar-bone had been to him when running for a touchdown in his football days; the one idea that filled his brain was to return to Mabel triumphant with the rescued dog in his arms, and he had room for no others.

He went as directly as he could to the part of the train in which was the carriage he had occupied, and found it without much difficulty when he was near enough to make out forms through the fog; the door of Mabel's compartment was open, and, as he sprang up the footboard, he heard the train behind rattling down on him with its whistle screeching infernally, and for the first time felt an uneasy recollection of the horribly fantastic injuries described in accounts of so many railway collisions.

But there was no time to think of this; at the other end of the carriage was the little round wicker-basket he had seen in Dolly's hands at the Chigbourne waiting-room, and in it was the terrier, sleeping soundly as she had anticipated. He caught up the little drowsy beast, which growled ungratefully, and turned to leap down with it to the ballast, when there was a sharp concussion, which sent a jangling forward shock, increasing in violence as it went, along the standing train, and threw him violently against the partition of the compartment.

Meanwhile the passengers of the first train, now that the worst was apparently over, and the faint shouts and screams from the embankment had calmed down, began to make their way in the direction of the sounds, and Mabel, holding Dolly fast by the hand, forced herself to follow them, though she was sick and faint with the dread of what she might see.

The first thing they saw was a crowd of eager, excited faces, all questioning and accusing the badgered officials of both trains at the same time. 'Why was an empty train left on the rails unprotected in this way? they might have been all killed.—It was culpable negligence all round, and there should be an inquiry—they would insist on an inquiry—they would report this to the traffic manager,' and so on.

The faces looked pale and ghastly enough in the fog, but all the speakers were evidently sound in wind and limb, and, as far as could be seen, neither train had left the rails—but where was the young man who had volunteered to recover the dog? 'Oh, Mabel,' cried Dolly, again and again. 'Frisk is killed, I'm sure of it, or he'd come to me—something has happened—ask, do ask.'

But Mabel dared not, for fear of hearing that a life had been nobly and uselessly sacrificed; she could only press through the crowd with the object of making her way to the carriage where the suspense would be ended.

'There's someone in one of the carriages!' she heard a voice saying as she got nearer, and her heart beat faster; and then the crowd parted somehow, and she saw Mark Ashburn come out of it towards her, with a dazed, scared smile on his pale face, and the little trembling dog safe under one arm.

Fortunately for Mark, the fog-signals had been set in time to do their work, and the second train was fitted with powerful brakes which, but for the state of the rails, would have brought it to without any collision at all; as it was, the shock had not been severe enough to damage the rolling-stock to any greater extent than twisting or straining a buffer or coupling-chain here and there, though it had thrown him against the corner of the net-rail with sufficient violence to slightly graze his forehead, and leave him stunned and a little faint for a few moments.
