BREAKDOWNS IN GENERAL. An express train was on its way from London to Edinburgh. It was running at sixty miles an hour, and the passengers, as comfortable as if they had been sitting in easy chairs by their own firesides, were engaged in reading, sleeping, talking or looking out of the windows. Not a thought of any impending trouble crossed their minds. Suddenly they felt a jar, followed by a jerk; the train slowed down, and within ten seconds had come to a standstill. Then there was general commotion, and heads appeared at every window, to see or inquire what was the matter. There was no station in sight, and no signal against them. Yet that train, which a few moments earlier had been speeding along in all its power and pride, had come to a dead stop. And when those passengers alighted from their compartments and began to investigate matters, they were no nearer a solution of the mystery. The train had not left the rails, the carriage wheels were intact, the engine was undamaged, the fires burning and the steam up. Yet something had happened, and whatever it was, it had rendered that train a useless mass of timber and steel for the time being. It was still a fine thing to look at, but as a means of locomotion it was of no more use than a child’s toy would have been. [Sidenote: The shock.] Yet, great as was the trepidation of those passengers, it was nothing to the shock experienced by the man who in the prime of life, and perhaps just when he bids fair to reach the heights towards which he has been striving with all his might for long years, suddenly finds that he is incapable of the very work of which he had prided himself he was master. It may be that he has toiled since youth in order to attain a certain position, and just when it comes within his reach his nerve fails him, and he cannot put out his hand to take it. The energy and ability which have carried him so far along the road fail him at the critical moment. Or it may be that he has struggled through laborious days and nights and amid many disappointments for fame. Just as he is about to realise his ambitions he breaks down, and becomes an embittered misanthrope. The genius which has enabled him to climb so many rungs of the ladder becomes inert, and he cannot mount the last step. Another spends his life in a good cause--philanthropy, religion, public work of any sort. At the very time when, by the experience he has gained, his years of greatest usefulness stretch before him, he is cut off, incapacitated by nervous debility.
