Meanwhile several members of the fire-fighting force that had been summoned from the various shops by the alarm, had made an effort to save from the red shed some of the more valuable of the contents. There were some machines in there, as well as explosives and chemicals, in addition to the store of carbide. But the fire was now too hot to enable much to be done in the way of salvage.
There Harry stood in silent contemplation for a long time, holding his carbide over the pile of ore that had been torn from the vein above. "It ain't much," came at last. "Not more 'n 'arf a ton. We won't get rich at that rate. And besides " he looked upward "we ain't even going to be getting that pretty soon. It's pinching out."
The North American Carbide & Metals technicians set up the circuits that were connected to the electrodes without any help from Sorensen. But just before they started to work, Sorensen said: "There's just one thing I think you ought to warn those men about, Mr. Thorn." "What's that?" Thorn asked. "If any of 'em tries to open that suitcase, they're likely to get blown sky high.
Harry started forward a step, then pausing, shifted his carbide and laid a hand on his companion's shoulder. "Boy," he said slowly, "we 're starting at something now and I don't know where it's going to lead us. There's a cave-in up 'ere, and if we 're ever going to get anywhere in this mine, we 'll 'ave to go past it. And I 'm afraid of what we 're going to find when we cut our wye through!"
At least they gave the alarm. Guess I'll ask Eradicate how he happened to notice. Oh, I say, Rad!" Tom called to the colored man. "Yais, sah, Massa Tom! I'se comin'!" the darky cried, as he finished piling up, at a safe distance from the fire, a number of cans of carbide. "How'd you happen to see the red shed ablaze?" Tom asked. "Why, it was jest dish yeah way, Massa Tom," began the colored man.
Another portion of the power is to be used to produce carbide of calcium for the manufacture of acetylene gas. At a recent electrical exhibition held in New York city a model of the Niagara plant was operated by an electric current brought from Niagara, 450 miles distant; and a collection of telephones were so connected that the spectator could hear the roar of the real cataract.
Here the Gotha River whirls itself down 120 feet in seven cataracts. They are rapids rather than falls, but it is the immense volume of water which makes them so impressive. Every year Trolhattan grows more and more disfigured by saw-mills, carbide of calcium works, and other industrial buildings sprouting up like unsightly mushrooms along the river-banks.
One of the earliest notable uses of the electric furnace in a large electro-chemical industry was for the production of carborundum, a carbide of silicon, which is remarkably useful as an abrasive, being available in the manufacture of grinding stones and other like purposes to replace emery and corundum.
Fairchild turned at the entrance of the mine and waited for the first of the miners and the accompanying gleam of his carbide. Then, they went within and to the shaft, the light shining downward upon the oily, black water below.
Seizing his carbide lamp, Fairchild made for the opening and crawled through, hurrying onward toward the chamber where the stope began, calling Harry's name at every step, in vain. The shadows before him lengthened, as the chamber gave greater play to the range of light. Fairchild rushed within, held high his carbide and looked about him.
