air into the trees and ditch at the side of the road were neither stunned nor seriously injured. They were consequently able, as soon as they could gather themselves up, to take the measures necessary to extinguish the fires in their locomotives which otherwise would speedly have spread to the _débris_ of the train. Had they not done so nothing could have saved the large number of passengers confined in the shattered cars. CHAPTER IV. ACCIDENTS AND CONSERVATISM. The four accidents which have been referred to, including that of April 17, 1836, upon the Manchester & Liverpool road, belong to one class. Though they covered a period of forty-two years they were all due to the same cause, the sudden derailment of a portion of the train, and its subsequent destruction because of the insufficient control of those in charge of it over its momentum. In the three earlier cases the appliances in use were much the same, for between 1836 and 1874 hardly any improvement as respects brakes had either forced its own way, or been forced by the government, into general acceptance in Great Britain. The Wollaston disaster, on the other hand, revealed a weak point in an improved appliance; the old danger seemed, indeed, to take a sort of pleasure in baffling human ingenuity. The Shipton accident, however, while one of the most fatal which ever occurred was also one of the most fruitful in results. This, and the accident of April 17, 1836, upon the Manchester & Liverpool road were almost precisely similar, though no less than thirty-eight years intervened between them. In the case of the first, however, no one was killed and consequently it was wholly barren of results; for experience has shown that to bring about any considerable reform, railroad disasters have, as it were, to be emphasized by loss of life. This, however, implies nothing more than the assertion that those responsible for the management of railroads do not differ from other men,--that they are apt, after some hair-breadth escape, to bless their fortunate stars for the present good rather than to take anxious heed for future dangers.
