With them there was nothing to break the blow, and the two hindmost carriages were crushed to fragments and their passengers scattered over the line. It was shortly after midnight, and the excursionists clambered out of the trains and rushed frantically about, impeding every effort to clear away the _débris_ and rescue the injured, whose shrieks and cries were incessant. The bodies of ten persons, one of whom had died of suffocation, were ultimately taken out from the wreck, and twenty-two others sustained fractures of limbs. At Des Jardines the couplings were too strong; at Port Jervis and at Helmshere they were not strong enough; at Carr's Rock they gave way not a moment too soon. "There are objections to a plenum and there are objections to a vacuum," as Dr. Johnson remarked, "but a plenum or a vacuum it must be." There are no arguments, however, in favor of putting railroad stations or sidings upon an inclined plane, and then not providing what the English call "catch-points" or "scotches" to prevent such disasters as those at Abergele or Helmshere. In these two instances alone the want of them cost over fifty lives. In railroad mechanics there are after all some principles susceptible of demonstration. That vehicles, as well as water, will run down hill may be classed among them. That these principles should still be ignored is hardly less singular than it is surprising. CHAPTER XIV. THE REVERE CATASTROPHE. The terrible disaster which occurred in front of the little station-building at Revere, six miles from Boston on the Eastern railroad of Massachusetts, in August 1871, was, properly speaking, not an accident at all; it was essentially a catastrophe--the legitimate and almost inevitable final outcome of an antiquated and insufficient system. As such it should long remain a subject for prayerful meditation to all those who may at any time be entrusted with the immediate operating of railroads. It was terribly dramatic, but it was also frightfully instructive; and while the lesson was by no means lost, it yet admits of further and advantageous study. For, like most other men whose lives are devoted to a special calling, the managers of railroads are apt to be very much wedded to their own methods, and attention has already more than once been called to the fact that, when any new emergency necessitates a new appliance, they not infrequently, as Captain Tyler well put it in his report to the Board of Trade for the year 1870, "display more ingenuity in finding objections than in overcoming them."
