failure there. Not that the furnace was not
doing as well as other furnaces in the West as to money-making, but
being so much larger than other furnaces its variations entailed much
more serious results. I am afraid my partner had something to answer
for in his Sunday morning visits to the Lucy Furnace when his good
father and sister left the house for more devotional duties. But even
if he had gone with them his real earnest prayer could not but have
had reference at times to the precarious condition of the Lucy Furnace
then absorbing his thoughts.

The next step taken was to find a chemist as Mr. Curry's assistant and
guide. We found the man in a learned German, Dr. Fricke, and great
secrets did the doctor open up to us. Iron stone 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.

At a most critical period when it was necessary for the credit of the
firm that the blast furnace should make its best product, it had been
stopped because an exceedingly rich and pure ore had been substituted
for an inferior ore--an ore which did not yield more than two thirds
of the quantity of iron of the other. The furnace had met with
disaster because too much lime had been used to flux this
exceptionally pure ironstone. The very superiority of the materials
had involved us in serious losses.

What fools we had been! But then there was this consolation: we were
not as great fools as our competitors. It was years after we had taken
chemistry to guide us that it was said by the proprietors of some
other furnaces that they could not afford to employ a chemist. Had
they known the truth then, they would have known that they could not
afford to be without one. Looking back it seems pardonable to record
that we were the first to employ a chemist at blast
furnaces--something our competitors pronounced extravagant.

The Lucy Furnace became the most profitable branch of our business,
because we had almost the entire monopoly of scientific management.
Having discovered the secret, it was not long (1872) before we decided
to erect an additional furnace. This was done with great economy
