5/37 Looking back it seems pardonable to record that we were the first to employ a chemist at blast furnaces--something our competitors pronounced extravagant. This was done with great economy as compared with our first experiment. The mines which had no reputation and the products of which many firms would not permit to be used in their blast furnaces found a purchaser in us. Those mines which were able to obtain an enormous price for their products, owing to a reputation for quality, we quietly ignored. A curious illustration of this was the celebrated Pilot Knob mine in Missouri. |
