The work of construction was slow and tedious; it came several times to a full stop for want of something that had not been provided beforehand and could not be made on the spot. Nearly another year passed.

Then one day smoke appeared at the top of one of Aaron’s four blast furnaces and people by this sign were notified that the great experiment was about to begin. In a general way the population knew, from what the workers said, that the intention was to produce steel and to produce it direct from the ore, and also that if such a thing were possible the iron industry would undergo a basic transformation.

All of that was exciting and very important, especially to a town like New Damascus, whose living was in iron. Yet it was no technical interest in a metallurgical process that moved people to gather in large numbers to witness the experiment. What they sensed was its human meaning. It symbolized a struggle between the former partners. The outcome might deeply affect the economic position of New Damascus in the course of time. Immediately it had tense dramatic value. It would prove which was the greater man and which was right,—Aaron who believed steel cheaply produced in large quantities by a continuous one-melt process would supersede iron and bring a new age to pass, or Enoch who scoffed, who was known privately to have predicted Aaron’s ruin, and who held that to think of getting steel direct from ore in that manner, skipping the iron stage, was as absurd as to think of getting a grandson from a grandfather, skipping the father. It was contrary to the way of nature.

All the iron wisdom of the community was with Enoch. All the inert scepticism with which people behold the trial of a new thing was on his side. But the heart was for Aaron. Everybody liked him still, as in the old days, and ardently wished him success. Besides, if he brought it off, Enoch Gib would be humbled. His tyrannical ways were increasingly complained of. New Damascus would rather be a steel town under Aaron than an iron town under Enoch.

With the outcome in suspense, the experiment itself was worth seeing as a spectacle. Nothing like it could have been imagined.

First, that strange, enormous tilting vessel, resembling a snail shell, was filled with fuel and fired under blast from the blowing engine until its clay-lined interior was white hot. Then it was tilted on its axis, emptied and tilted back again. Next the molten iron from the blast furnace, instead of being run off in the sand to make the sow the pigs devour, was tapped into that great ladle in chains, hoisted on high, and poured into the white hot gullet of the tilting vessel. At the same time the blowing engine to force air through the perforations in the bottom was set in fast motion with a terrible roar. A blast of air at high pressure began now to pass upward through the fluid metal.

A series of awesome pyrotechnics ensued.

In the belly of the tilting vessel occurred a dry, chortling sound, followed by a dull, regular clapping, as of Plutonic amusement and applause. From the mouth of the vessel issued millions of sparks, particles burning brilliantly in the air. This went on for seven or eight minutes. Suddenly the sparks went out and a dull, sluggish red flame appeared, turning bright and yellowish, then becoming high, brilliant and dart-like. After several minutes terrific detonations began to take place in the vessel. With each detonation the flame shot higher. This uproar was succeeded by a period of calm. The yellowish, dart-like flame rising from the throat of the vessel was replaced by a long, white flame, which stood for several seconds proudly, then trembled, tore at the edges and abruptly collapsed. Dense black smoke issued from the mouth of the crater and the scene was dark. This was the moment at which the metal itself began to burn. The workers, uttering shrill cries of anxiety, readiness, encouragement and damnation, seized the levers controlling the vessel and tilted it over to a spilling position. Through the black smoke that corked its throat burst the fluid, blazing metal, hissing like a tortured serpent, alive in every incandescent crystal, yet doomed quickly to cool and blacken, every element touching it being fatally adverse. Men in waiting caught it headfirst neatly into a trundle pot and wheeled it off to be decanted into sand molds, like pig iron molds, but smaller.

The experiment was finished. The test was yet to come. That waited on the cooling. What was in those molds? Those squarish lumps blackening in the sand,—what would they turn out to be? No one knew.

Aaron waited until one was cool enough to handle. Then placing it like a stick of kindling against the chopping block, he hit it one blow in the middle with a sledge hammer. It broke with an ironic, ringing sound and lay in two pieces apart. He never stooped to pick them up. Without a word he dropped the hammer and walked away.
