American Inventions and Inventors

CHAPTER VI.

RAILROADS.

Up to this time progress had been more marked upon the water than upon the land. On the land travelers were still limited to human power and horse power. On the water, however, not only human power and wind were used, but also horse power and even steam power. The steamboat was thought to be the most rapid means of transit possible. No energy was known greater than that of steam; therefore no new source of power was expected.

If steam could aid water navigation, could it not be used in land travel? This question was ever present in the minds of inventors, mechanics, and travelers on both sides of the ocean. Little by little an answer was obtained, and the field of steam was enlarged. Even before Fulton's trial trip, the first step in the direction of the railroad was taken, though steam had nothing to do with this first practical experiment.

The city of Boston was built upon three hills, two of which have now been almost entirely moved away. Upon the third, called Beacon Hill, was built the State House. Early in this century the top of this hill was lowered by carrying away the gravel. For this purpose a tramway was built. This consisted of two sets of rails or tracks from the top to the bottom of the hill, upon which cars were used. The full car on one track ran down of its own weight, pulling up the empty car on the other track. This was the first use of rails in this country.

The first permanent tramway was built in Pennsylvania. Thomas Leifer owned a stone quarry about three-quarters of a mile from the nearest wharf on the Delaware River. He desired to carry his stone to tide water more easily than by the ordinary methods. Accordingly he built a tramway from the quarry to the wharf, and placed upon the tracks an ordinary wagon. To this he attached horses and had what we should call a horse car. The rails made a smooth road over which his horses could draw five tons as easily as one ton over the common roads. This tram was used regularly for eighteen years.

One-half of the steam railroad had now been invented. The tramway was the railroad—now steam must be applied. That was all. But that was not so easy as it would seem now. Year after year passed and no one attempted it. Doubtless many persons felt certain that the steam railroads were coming some time and that they would be of value, just as to-day many people expect that travel through the air is coming some time. At the same time there were many who did not believe that steam could be used for land travel at all; while others did not care to have it come for fear that travel would be made too speedy.

One of the leading English magazines took occasion to express its opinion concerning a proposed railway: "What can be more absurd and ridiculous than the prospect held out of locomotives traveling twice as fast as stage coaches! We should as soon expect the people of Woolwich to suffer themselves to be fired off upon one of Congreve's rockets as trust themselves to the mercy of a machine going at such a rate. We trust that Parliament will, in all railways it may sanction, limit the speed to eight or nine miles an hour, which is as great as can be ventured on with safety." What would this writer say to the safety of the trains of to-day, as they make forty fifty, sixty, and even seventy miles an hour?

Many of the inventions which have done the most for mankind have been made by Americans, but we owe the locomotive to an Englishman. George Stephenson from early boyhood devoted himself to the study of engines and machinery. When but thirteen years of age he assisted his father in the care of an engine at a coal mine near Newcastle. Working by day as an engineman, and studying by night in a night school, he prepared himself for his future work. He won the confidence of his employers, especially that of Lord Ravensworth, who supplied him with funds to build a "traveling engine" to run on the rails of the tramroad between the mines and the shipping port, nine miles distant. July 25th, 1814, Stephenson made a successful trip with his locomotive, "My Lord," which pulled the coal cars at the rate of four miles an hour.
