A large party of excursionists were returning from a rowing match on a special train consisting of two locomotives and twenty-one cars. There had been great delay in getting ready for the return, so that when it neared Wollaston the special was much behind the time assigned for it. Meanwhile a regular freight train had left Boston, going south and occupying the outward track. At Wollaston those in charge of this train had occasion to stop for the purpose of taking up some empty freight cars, which were standing on a siding at that place; and to reach this siding it was necessary for them to cross the inward track, temporarily disconnecting it. The freight train happened to be short-handed, and both its conductor and engineer supposed that the special had reached Boston before they had started out. Accordingly, in direct violation of the rules of the road and with a negligence which admitted of no excuse, they disconnected the inward track in both directions and proceeded to occupy it in the work of shunting, without sending out any signals or taking any precautions to protect themselves or any incoming train. It was after dark, and, though the switches were supplied with danger signals, these were obscured by the glare of the locomotive head-light. Under these circumstances the special neared the spot. What ensued was a curious illustration of those narrow escapes through which, by means of improved appliances or by good luck, railroad accidents do not happen; and an equally curious illustration of those trifling derangements which now and again bring them about. In this case there was no collision, though a freight train was occupying the inward track in front of the special. There should have been no derailment, though the track was broken at two points. There would have been no accident, had there been no attempt made to avert one. Seeing the head-light of the approaching special, while yet it was half a mile off, the engineer of the freight train realizing the danger had put on all steam, and succeeded, though by a very narrow margin, in getting his locomotive and all the cars attached to it off of the inward track and onto the outward, out of the way of the special. The inward track was thus clear, though broken at two points. The switches at those points were, however, of the safety pattern, and, if they were left alone and did their work, the special would simply leave the main track and pass into the siding, and there be stopped. Unfortunately the switches were not left alone. The conductor of the freight train had caught sight of the head-light of the approaching locomotive at about the same time as the engineer of that train. He seems at once to have realized the possible consequences of his reckless neglect of precautions, and his one thought was to do something to avert the impending disaster. In a sort of dazed condition, he sprang from the freight car on which he was standing and ran to the lever
