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. The liquid metal in the hearth is called slag. The iron oxide is put in it to make it more basic for the chemical reaction that is to take place.
It is the village of the Adirondack Iron-Works, where the streets of gaunt houses are falling to pieces, tenantless; the factory-wheels have stopped; the furnaces are in ruins; the iron and wooden machinery is strewn about in helpless detachment; and heaps of charcoal, ore, and slag proclaim an arrested industry.
"I didn't," said Raut. "I wouldn't have had you run over then for the world," said Horrocks. "For a moment I lost my nerve," said Raut. Horrocks stood for half a minute, then turned abruptly towards the ironworks again. "See how fine these great mounds of mine, these clinker-heaps, look in the night! That truck yonder, up above there! Up it goes, and out-tilts the slag.
Even when I have good dreams, I personally am as happily and blessedly silent in them as the beast of the field. I shudder at the thought of reaching down into my soul and pulling out old, rusty things and showing them to you—mouldy fruit, slag, junk—showing them to you, you who knew me when all within me was crystal.”
A boy tugging over a shoe-last in Haverhill, Mass., was told by his mother to give himself to making better and stronger lasts. Twenty years of enthusiastic study ended, and he was president of one of the greatest of our railways. In 1870, a youth sat upon the slag heap of a mine in California.
Hundreds of chimneys we speak literally are vomiting forth that white, peculiar-looking, and unmistakable vapour called copper-smoke. Enormous masses of that ugly, black, silicious refuse, known in the smelting vocabulary as 'slag, is piled above and around in such quantity as to change even the physical appearance of the country. But this is not all.
And Peter waited, holding his breath, listening for an answer to the cry that went out for Jolly Roger McKay. The glory of July midnight, with a round, full moon straight overhead, followed the stress of storm. The world had been lashed and inundated, every tree whipped of its rot and slag, every blade of grass and flower washed clean.
Pointed downward the latter spasmodically discharged a rush of air with a vast creasing of their dusty leather. A procession of men were wheeling and dumping slag into a dreary area beyond. There was a stir of constant life about the Furnace, voices calling, the ringing of metal on metal, the creak of barrows, dogs barking. The plaintive melody of a German song rose on the air.
Those who are accustomed to the celebrated "Pears" can scarcely understand what an addition to cleanliness and comfort resulted from this coarsely manufactured article. Gulls' eggs were found in great quantity on the cliffs, and the discovery and capture of wild pigs added to the luxury of their table which latter, by the way, was an ingenious contrivance of Joe Slag.
We are dwelling on a cooled crust all over Southern Hawaii, the whole region is recent lava, and between this and the sea there are several distinct lines of craters thirty miles long, all of which at some time or other have vomited forth the innumerable lava streams which streak the whole country in the districts of Kau, Puna, and Hilo. In fact, Hawaii is a great slag.
