The next machine that takes up the work is called “the teazer:” it has a greater number of cylinders than the willow, with shorter teeth, about an inch in length, and hooked, and some of the cylinders have coarse wire cards. Having passed twice or thrice through the teazer, the wool is transferred to that part of the mill called, by way of pre-eminence, “the machine-room,” where the great scribbling machines, or, as they are styled, “scribblers,” are placed. These machines have a great number of cylinders of different sizes covered with wire cards of various degrees of fineness, so arranged that they take the wool from one another, separating the fibres, and transferring it until it has passed quite over every cylinder, and is carded out at the farther end of the machine (sixteen or eighteen feet from where it was put in) in a thin flake like gauze. Having been run through two or three scribblers of various fineness, it is passed to the carding machine, or “carder,” which resembles the “scribbler,” but is smaller, and instead of the wool falling out at the end in a flake, it is caught by a fluted cylinder of wood, which, revolving in a semi-cylindrical box, divides and converts it into separate soft rolls, about the thickness of ordinary sash rope; and these are thrown out upon a sheet of canvass stretched horizontally upon rollers, which from its slowly moving, so as to prevent one roll from falling upon another, is called “the creeper.” The rolls are taken to “the billy,” a sort of preliminary spinning-machine, sometimes worked by the water-wheel, but (as yet, especially in Ireland) more generally by a man called a “slubber,” who is enabled by it to form from fifty to one hundred threads at a time, children being employed to stick the ends of the rolls together, which is done by lapping a small portion of the tip of one on the other which lies on the “billy-sheet,” and then giving them a slight rub. The soft thick thread which the slubber forms is made up in conical rolls or “cops,” and is taken to the spinning-machine, “the mule,” which has now quite superseded the spinning-jenny, which in its day superseded the spinning-wheel. The wheel could spin only one thread at a time: the jenny was first made to spin thirty, then forty, then fifty, sixty, seventy, and eighty threads at once, by a man’s hand. By the “mule,” worked by water, a man can now spin from five hundred to one thousand threads of woollen yarn, and of cotton two or three thousand, at once.
