doubts came upon him again. Was it wise to be here? If Horrocks
did know--everything! Do what he would, he could not resist a
violent trembling. Right under foot was a sheer depth of seventy
feet. It was a dangerous place. They pushed by a truck of fuel to
get to the railing that crowned the place. The reek of the
furnace, a sulphurous vapor streaked with pungent bitterness,
seemed to make the distant hillside of Hanley quiver. The moon was
riding out now from among a drift of clouds, halfway up the sky
above the undulating wooded outlines of Newcastle. The steaming
canal ran away from below them under an indistinct bridge, and
vanished into the dim haze of the flat fields towards Burslem.

"That's the cone I've been telling you of," shouted Horrocks;
"and, below that, sixty feet of fire and molten metal, with the air
of the blast frothing through it like gas in soda-water."

Raut gripped the hand-rail tightly, and stared down at the
cone. The heat was intense. The boiling of the iron and the
tumult of the blast made a thunderous accompaniment to Horrocks'
voice. But the thing had to be gone through now. Perhaps, after
all . . .

"In the middle," bawled Horrocks, "temperature near a thousand
degrees. If _you_ were dropped into it . . . . flash into
flame like a pinch of gunpowder in a candle. Put your hand out and
feel the heat of his breath. Why, even up here I've seen the
rain-water boiling off the trucks. And that cone there. It's a
damned sight too hot for roasting cakes. The top side of it's
three hundred degrees."
