(p. 246) We found . . . a learned German, Dr. Fricke, and great secrets did the doctor open up to us. [Ore] from mines that had a high reputation was now found to contain ten, fifteen, and even twenty per cent less iron than it had been credited with. Mines that hitherto had a poor reputation we found to be now yielding superior ore. The good was bad and the bad was good, and everything was topsy-turvy. Nine-tenths of all the uncertainties of pig iron making were dispelled under the burning sun of chemical knowledge.
What fools we had been! But there was this consolation: we were not as great fools as our competitors . . . Years after we had taken chemistry to guide (p. 247) us [they] said they could not afford to employ a chemist. Had they known the truth then, they would have known they could not afford to be without one.
