Mrs Marrot obediently retreated to a safe distance. Then the stalwart men threw open the furnace door. Mrs Marrot exclaimed, almost shrieked, with surprise at the intense light which gushed forth, casting even the modified daylight of the place into the shade. The proceedings of the stalwart men thereafter were in Mrs Marrot’s eyes absolutely appalling—almost overpowering,—but Mrs M was tough both in mind and body. She stood her ground. Several of the men seized something inside the furnace with huge pincers, tongs, forceps—whatever you choose to call them—and drew partly out an immense rudely shaped bar or log of glowing irons thicker than a man’s thigh. At the same time a great chain was put underneath it, and a crane of huge proportions thereafter sustained the weight of the glowing metal. By means of this crane it was drawn out of the furnace and swung round until its glowing head or end came close to the tongue before mentioned. Then some of the stalwart men grasped several iron handles, which were affixed to the cool end of the bar, and prepared themselves to act. A signal was given to a man who had not hitherto been noticed, he was so small in comparison with the machine on which he stood—perhaps it would be better to say to which he stuck, because he was perched on a little platform about seven or eight feet from the ground, which was reached by an iron ladder, and looked down on the men who manipulated the iron bar below.
On receiving the signal, this man moved a small lever. It cost him no effort whatever, nevertheless it raised the iron tongue about six feet in the air, revealing the fact that it had been resting on another square block of iron embedded in the earth. This latter was the anvil. On the anvil the end of the white-hot bar was immediately laid. Another signal was given, and down came the “five-carts-of-coals weight” with a thud that shook the very earth, caused the bar partially to flatten as if it had been a bit of putty, and sent a brilliant shower of sparks over the whole place. Mrs Marrot clapped both hands on her face, and capped the event with a scream. As for Bob, he fairly shouted with delight.
Blow after blow was given by this engine, and as each blow fell the stalwart men heaved on the iron handles and turned the bar this way and that way, until it was pounded nearly square. By this time Mrs Marrot had recovered so far as to separate her fingers a little, and venture to peep from behind that protecting screen. By degrees the unwieldy mass of misshapen metal was pounded into a cylindrical form, and Will Garvie informed his friends that this was the beginning of the driving-axle of a locomotive. Pointing to several of those which had been already forged, each having two enormous iron projections on it which were afterwards to become the cranks, he said—
“You’ll see how these are finished, in another department.”
But Mrs Marrot and Bob paid no attention to him. They were fascinated by the doings of the big hammer, and especially by the cool quiet way in which the man with the lever caused it to obey his will. When he moved the lever up or down a little, up or down went the hammer a little; when he moved it a good deal the hammer moved a good deal; when he was gentle, the hammer was gentle; when he gave a violent push, the hammer came down with a crash that shook the whole place. He could cause it to plunge like lightning to within a hair’s-breadth of the anvil and check it instantaneously so that it should not touch. He could make it pat the red metal lovingly, or pound it with the violence of a fiend. Indeed, so quick and sympathetic were all the movements of that steam-hammer that it seemed as though it were gifted with intelligence, and were nervously solicitous to act in prompt obedience to its master’s will. There were eleven steam-hammers of various sizes in this building, with a staff of 175 men to attend to them, half of which staff worked during the day, and half during the night—besides seven smaller steam-hammers in the smiths’ shops and other departments.
With difficulty Will Garvie tore his friends away from the big hammer; but he could not again chain their attention to anything else, until he came to the pair of scissors that cut iron. With this instrument Mrs Marrot at first expressed herself disappointed. It was not like a pair of scissors at all, she said, and in this she was correct, for the square clumsy-looking blunt-like mass of iron, about five feet high and broad, which composed a large portion of it, was indeed very unlike a pair of scissors.
“Why, mother,” exclaimed Bob, “you didn’t surely expect to see two large holes in it for a giant’s thumb and fingers, did you?”
“Well, but,” said Mrs Marrot, “it ain’t got no blades that I can see.”
“I’ll let ’ee see ’em, Missis, in a minute,” said a workman who came up at that moment with a plate of iron more than a quarter of an inch thick. “Turn it on, Johnny.”
A small boy turned on the steam, the machine moved, and Will Garvie pointed out to Mrs Marrot the fact that two sharp edges of steel in a certain part of it crossed each other exactly in the manner of a pair of scissors.
