We have already told of a very few of the earliest and most famous American locomotives; the _Stourbridge Lion_, which Horatio Allen brought to the Delaware & Hudson Company; the _Best Friend_, which was built in New York City, and which went to Charleston, South Carolina, to be the first American locomotive to run in the United States, the _De Witt Clinton_, which awoke the echoes of the Hudson and Mohawk valleys in a single day; and the _Tom Thumb_, built by Peter Cooper, which induced the directors of the Baltimore & Ohio Railroad to change their motive power from horses to steam, and so opened a great new development for their property. A little while after Cooper's _Tom Thumb_ had achieved the astounding feat of beating a team of horses in hauling a railroad coach, the directors of the B. & O. offered a prize of $4,000 "for the most approved engine that shall be delivered for trial upon the road on or before June 1, 1831; and $3,500 for the engine which shall be adjudged the next best." It was determined in this prospectus that "the engine, when in operation must not exceed three and one-half tons weight and must, on a level road, be capable of drawing day by day fifteen tons, inclusive of the weight of wagons, fifteen miles an hour." Three locomotives answered this generous offer. Of them but one, the _York_, oftener called the _Arabian_, built at York, Pa., by Davis & Gartner, and hauled to Baltimore by horses over the turnpikes, was of practical service. Phineas Davis was a watch and clock maker, but he succeeded in devising a locomotive that was the forerunner of the famous _Grasshopper_ upon the Baltimore & Ohio. Better name was never given to a locomotive, the rude and ungainly angles formed by rods and levers giving a distinct resemblance to the long-legged bugs. Yet the Grasshoppers served their purpose. In the late eighties, the _Arabian_ was still in service in the Mount Clare yards at Baltimore. With a single exception, it never had an accident or even left the rails. That exception was just before the completion of the Washington branch, and Davis was a passenger upon the engine. It was going at a fair rate of speed when suddenly it rolled over upon its side in the ditch. No one was hurt, save Davis, who was instantly killed. It seemed a strange caprice of Fate, for although careful examination was immediately made, both of the engine and of the track, no reason could ever be assigned for the accident.
