The engine went through its usual performances, dragging a heavy load of coal-wagons at about six miles an hour with apparent ease, at which Mr. James expressed his extreme satisfaction, and declared to Mr. Losh his opinion that Stephenson "was the greatest practical genius of the age," and that, "if he developed the full powers of that engine (the locomotive), his fame in the world would rank equal with that of Watt." Mr. James informed Stephenson and Losh of his survey of the proposed tram-road between Liverpool and Manchester, and did not hesitate to state that he would thenceforward advocate the construction of a locomotive railroad instead of the tram-road which had originally been proposed. [Illustration: MAP OF LIVERPOOL AND MANCHESTER RAILWAY. [Eastern Part.]] Stephenson and Losh were naturally desirous of enlisting James's good services on behalf of their patent locomotive, for as yet it had proved comparatively unproductive. They believed that he might be able so to advocate it in influential quarters as to insure its more extensive adoption, and with that object they proposed to give him an interest in the patent. Accordingly, they entered into an agreement by which they assigned to him one fourth of any profits which might be derived from the use of the patent locomotive on any railways constructed south of a line drawn across England from Liverpool to Hull. The arrangement, however, led to no beneficial results. Mr. James endeavored to introduce the engine on the Moreton-on-Marsh Railway, but it was opposed by the engineer of the line, and the attempt failed. He next urged that a locomotive should be sent for trial upon the Merstham tram-road; but, anxious though Stephenson was as to its extended employment, he was too cautious to risk an experiment which might bring discredit upon the engine; and the Merstham Road being only laid with cast-iron plates which would not bear its weight, the invitation was declined.
