The credit of constructing the first permanent tramway in America may therefore be rightly given to Thomas Leiper. He was the owner of a fine quarry not far from Philadelphia, and was much concerned to find an easy mode of carrying stone to tide-water. That a railway would accomplish this end he seem to have had no doubt. To test the matter, and at the same time afford a public exhibition of the merits of tramways, he built a temporary track in the yard of the Bull's Head Tavern in Philadelphia. The tramway was some sixty feet long, had a grade of one inch and a half to the yard, and up it, to the amazement of the spectators, one horse used to draw a four-wheeled wagon loaded with a weight of ten thousand pounds. This was the summer of 1809. Before autumn laborers were at work building a railway from the quarry to the nearest landing, a distance of three quarters of a mile. In the spring of 1810 the road began to be used and continued in using during eighteen years.
