It did not require strength, but a certain skill, which, unfortunately, childhood possessed more than the adult. Not power, but dexterity, watchfulness, quickness and the ability to walk—as children walk—and watch—as age should watch.

No wonder that in a few months the child becomes, not the flesh and blood of its heredity, but the steel and wood of its environment.

Bull Run and Seven Days were doffers, and confined to the same set of frames. They followed their sisters, taking off the full bobbins and throwing them into a cart and thrusting an empty bobbin into its place. This requires an eye of lightning and a hand with the quickness of its stroke.

For it must be done between the pulsings of the Big Thing's heart—a flash, a snap, a snarl of broken thread—up in the left hand flies the bobbin from its disentanglement of thread and skein, and down over the buzzing point of steel spindles settles the empty bobbin, thrust over the spindle by the right.

It is all done with two quick movements—a flash and a jerk of one hand up, and the other down, the eye riveted to the nicety of a hair's breadth, the stroke downward gauged to the cup of a thimble, to settle over the point of the spindle's end; for the missing of a thread's breadth would send a spindle blade through the hand, or tangle and snap a thread which was turning with a thousand revolutions in a minute.

Snap—bang! Snap—bang! One hundred and twenty times—Snap—bang! and back again, went the deft little workers pushing their cart before them.

Full at last, their cart is whirled away with flying heels to another machine.

It was a steady, lightning, endless track. Their little trained fingers betook of their surroundings and worked like fingers of steel. Their legs seemed made of India rubber. Their eyes shot out right and left, left and right, looking for the broken threads on the whirling bobbins as hawks sweep over the marsh grass looking for mice, and the steel claws, which swooped down on the bobbins when they found it, made the simile not unsuitable.

Young as she was, Shiloh managed one of these harnessed, fiery lines of dancing witches, pirouetting on boards of hardened oak or hickory. Up and down she walked—up and down, watching these endless whirling figures, her bare fingers pitted against theirs of brass, her bare feet against theirs shod with iron, her little head against theirs insensate and unpitying, her little heart against theirs of flame which throbbed in the boiler's bosom and drove its thousand steeds with a whip of fire.

In the bloodiest and cruelest days of the Roman Empire, man was matched against wild beasts. But in the man's hand was the blade of his ancestors and over his breast the steel ribs which had helped his people to conquer the world.
