The bait took. He launched forth into a description of several spans of horses he had seen and stables he had visited. I asked him if he could possibly stay over and select the horses. I knew very well that he would wish to see them and drive them many times which would keep him busy. It happened just as I expected. He purchased a splendid pair, but then another difficulty occurred about transporting them to Pittsburgh. He would not trust them by rail and no suitable boat was to leave for several days. Providence was on my side evidently. Nothing on earth would induce that man to leave the city until he saw those horses fairly started and it was an even wager whether he would not insist upon going up on the steamer with them himself. We held the bridge. "Pipe" made a splendid Horatius. He was one of the best men and one of the most valuable partners I ever was favored with, and richly deserved the rewards which he did so much to secure. The Keystone Bridge Works have always been a source of satisfaction to me. Almost every concern that had undertaken to erect iron bridges in America had failed. Many of the structures themselves had fallen and some of the worst railway disasters in America had been caused in that way. Some of the bridges had given way under wind pressure but nothing has ever happened to a Keystone bridge, and some of them have stood where the wind was not tempered. There has been no luck about it. We used only the best material and enough of it, making our own iron and later our own steel. We were our own severest inspectors, and would build a safe structure or none at all. When asked to build a bridge which we knew to be of insufficient strength or of unscientific design, we resolutely declined. Any piece of work bearing the stamp of the Keystone Bridge Works (and there are few States in the Union where such are not to be found) we were prepared to underwrite. We were as proud of our bridges as Carlyle was of the bridge his father built across the Annan. "An honest brig," as the great son rightly said.
