There was the usual obstructive person in the train who required to be logically convinced first of the necessity for disturbing himself; he put his head angrily out of a window near Mark's: 'Here, guard!' he shouted importantly; 'what's all this? _Why_ am I to get out?' 'Because you'd better,' said the guard, shortly. 'But why--where's the platform? I insist on being taken to a platform--I'm not going to break my leg getting out here.' Several people, who had half opened their doors, paused on the steps at this, as if recalled to a sense of their personal dignity. 'Do as you please, sir,' said the official; 'the engine's broke down, and we may be run into any minute in this fog; but if you'd be more comfortable up there----' There was no want of alacrity after that, the obstructive man being the first down; all the rosy-faced gentlemen hopped out, some of the younger ones still grasping half-played hands of 'Nap' or 'Loo,' and made the best of their way down the embankment, and several old ladies were got out in various stages of flutter, narrowly escaping sprained ankles in the descent. Mark, who had seen his opportunity from the first, had rushed to the door of the next compartment, caught Dolly in his arms as she jumped down, and, hardly believing in his own good fortune, held Mabel's hand in his for one happy moment as she stepped from the high and awkward footboard. 'Down the slope, quick,' he cried to them; 'get as far from the line as you can in case of a smash.' Mabel turned a little pale, for she had not understood till then that there was any real danger. 'Keep close to me, Dolly,' she said, as they went down the slope; 'we're safe here.' The fog had gathered thick down in the meadows, and nothing could be seen of the abandoned train when they had gone a few paces from the foot of the embankment; the passengers were moving about in excited groups, not knowing what horrors they might not be obliged to witness in the next few minutes. The excitement increased as one of them declared he could hear the noise of an approaching train. 'Only just in time--God help them if they don't pull up!' cried some, and a woman hoped that 'the poor driver and stoker were not on the engine.' Dolly heard this and broke from Mabel with a loud cry--'Mabel, we've left Frisk!' she sobbed; 'he'll be killed--oh, my dog will be killed--he mustn't be left behind!' And, to Mark's horror, she turned back, evidently with the idea of making for the point of danger; he ran after her and caught the little silvery-grey form fast in his arms. 'Let me go!' cried Dolly, struggling; 'I must get him back--oh, I must!' 'He'll have jumped out by this time--he's quite safe,' said Mark in her ear. 'He was sound asleep in his basket, he'll never wake if I don't call to him--why do you hold me? I tell you I _will_ go!' persisted Dolly.
