"George Stephenson, an Englishman," replied her father. "For some time he had been experimenting with steam locomotives at the Newcastle coal mines where some agency stronger than mules or horses was needed to carry the products from one place to another. He had no idea of transporting people when he began to work out the suggestion. All he thought of was a coal train which would run on short lengths of track from mine to mine. But the notion assumed unexpected proportions until the Darlington road, the most ambitious of his projects, reached the astonishing distance of thirty-seven miles. When the rails for it were laid the engineer intended it should be used merely for coal transportation, as its predecessors had been; but some of the miners who lived along the route and were daily obliged to go back and forth to work begged that some sort of a conveyance be made that could also run along the track and enable them to ride to work instead of walking. So a little log house not unlike a log cabin, with a table in the middle and some chairs around it, was mounted on a cart that fitted the rails, and a horse was harnessed to the unique vehicle." "And it was this log cabin on wheels that gave Stephenson his inspiration for a railroad train!" gasped Doris. "Yes," nodded her father. "When the engineer saw the crude object the first question that came to him was why could not a steam locomotive propel cars filled with people as well as cars filled with coal. Accordingly he set to work and had several coach bodies mounted on trucks, installing a lever brake at the front of each one beside the coachman's box. In front of the grotesque procession he placed a steam locomotive and when he had fastened the coaches together he had the first passenger train ever seen." "It must have been a funny looking thing!" Steve exclaimed, smiling with amusement at the picture the words suggested. "It certainly was," agreed his father. "If you really wish to know how funny, some time look up the prints of this great-great-grandfather of our present-day Pullman and you will be well repaid for your trouble; the contrast is laughable." "But was this absurd venture a success?" queried Mrs. Tolman incredulously. "Indeed it was!" returned her husband. "In fact, Stephenson, like Watt, was one of the few world benefactors whose gift to humanity was instantly hailed with appreciation. The railroad was, to be sure, a wretched little affair when viewed from our modern standpoint, for there were no gates at the crossings, no signals, springless cars, and every imaginable discomfort. Fortunately, however, our ancestors had not grown up amid the luxuries of this era, and being of rugged stock that was well accustomed to hardships of every variety they pronounced the invention a marvel, which in truth it was. "You've said it!" chuckled Steve in the slang of the day.
