The gun was tried on the bank of the Hudson, the Palisades opposite being the target. The inventor declared that every shot hit the mark, but some evil-minded persons insisted that they fell into the water within a quarter of a mile of the shore from which they were fired. About the same time the absurdity of sending into the field a tank of water, a boiler, an engine and the gun, on separate wheels, connected by pipes or belting, which would be ruined by the least damage to anything, began to dawn on the enthusiasts, and the thing was abandoned. I furnished one of my first governors to Mr. James Horner to regulate a rolling-mill near Boonton, N. J., a sale which is worth recording. This mill was employed in rolling steel pretty high in carbon into rods for making gimlets, and the three-high train had not yet issued from the brain of Mr. Fritz. The rolling was slow work. The resistance brought down the speed of the engine before the governor could act, and they could have only one pass in the rolls at a time. The workmen had to carry the end of the rod around and insert it in the next groove after it had run out of the former one. The rod would be black before it was finished, and often it was difficult to get it finished at all. I do not know of any change that so much impressed me at the time as did that which followed the putting of my governor on this engine. The full speed was kept up, the billets seemed to rush through the rolls, two and even three passes could be in them at the same time, and the rods were still at a dull red heat when finished. This success induced me to make a raid on Pittsburg. I found there very different conditions. They then rolled nothing but iron, so far as I saw or heard. In the first mill I visited, after I had discussed the subject with one of the proprietors, an old man came up to me and said, “Do you see that chair? I have sat in that chair twenty-four years.” The chair corroborated his story. “I watch the rolls; when a bar enters them, I turn on more steam; when it goes out I shut it off. If you put in a governor that will do as well, I shall be discharged. I don’t know how to do anything else; I have a family dependent on me, and I don’t know what I should do.” I did not hesitate long about what I should do. I could not improve on the old man’s action. He regulated the speed perfectly. The only result of my success would be to beggar him. Superseding hand labor by machinery I did not in this particular case care to be responsible for. I concluded that the Pittsburg way was good enough for them, and took the next train for home.
