AUTOBIOGRAPHY OF JOHN FRITZ 8l
house that evening for the purpose of having a talk with him in order to get him to remain. Mr. Perry, being an tmeducated man, who could neither read nor write, supposed it was a social and that he would get a drink, consequently caUed. Mr. Kunzie, being a thorough chemist and well read up on the theory of blast-furnace practice, at once commenced to talk to Mr. Perry about the effect the dif¬ ferent gases had on the proper working of the fumace and had much to say about oxygen, hydrogen, and nitrogen. Mr. Perry, supposing he had been invited to have a drink, said to Mr. Kunzie, " I don't know a damn thing about oxy- gin or hydro-gin, if you have some good HoUand gin I will take some of that."
Here let me say the problem in the early forties was, — can iron be made in the blast furnace with anthracite coal as a fuel? It was said (and I beUeve correctly), that Mr. Kunzie had experimented vnth a cupola to learn if heat sufficient to smelt iron ore could be gotten vnth anthracite coal; having demonstrated to his satisfaction that sufficient heat could be so gotten he then built the furnace to prove it practically. But while he was experimenting, Mr. David Thomas (afterwards affectionately caUed Father Thomas in honor of his being the first man in this coimtry to make iron with purely mineral coal as a fuel, on a commercial basis) built the Number One furnace for the Crane Iron Company's Works at Catasauqua, then caUed CraneviUe, and it was a success from the start.
Mr. Kunzie deserves much credit for what he did and had he been so fortunate as to have had a good practical man with him he would have made a success. In changing the old plant, I saw some good ideas had they been properly carried out.
In a short time we had that part of the plant that was to be changed torn out and the place cleaned up aU ready for
