WRESTING A PRIZE FROM NATURE'S HAND.
After melting down the pig-iron as quickly as possible, which took me thirty minutes, there was a pause in which I had time to wipe the back of my hand on the dryest part of my clothing (if any spot was still dry) and with my sweat cap wipe the sweat and soot out of my eyes.

For the next seven minutes I "thickened the heat up" by adding iron oxide to the bath.

This was in the form of roll scale.

The furnace continued in full blast till that was melted.
