It seems to me impossible to explain clearly in words, though it is simple enough in execution, the laying of the piece, the orderly placing the warp on the warp-beam. The warping-bars are entirely detached from the loom, are an accessory, not a part of it. They are two upright bars of wood, each holding a number of wooden pins set at right angles to the bars, and held together by crosspieces. Let forty full spools be placed in the skarne, one above the other. The free ends of threads from the spools are gathered in the hand, and fastened to a pin at the top of the warping-bars. The group of threads then are carried from side to side of the bars, passing around a pin on one bar, then around a pin on the opposite bar, to the extreme end; then back again in the same way, the spools revolving on wires and freely playing out the warp-threads, till a sufficient length of threads are stretched on the bars. Weavers of olden days could calculate exactly and skilfully the length of the threads thus wound. You take off twenty yards of threads if you want to weave twenty yards of cloth. Forty warp-threads make what was called a bout or section. A warp of two hundred threads was designated as a warp of five bouts, and the bars had to be filled five times to set it unless a larger skarne with more spools was used. From the warping-bars these bouts are carefully wound on the warp-beam. Without attempting to explain farther, let us consider the yarn-beam neatly wound with these warp-threads and set in the loom--that the "warping" and "beaming" are finished. The "drawing" or "entering" comes next; the end of each warp-thread in regular order is "thumbed" or drawn in with a warping-needle through the eye or "mail" of the harness, or heddle. The heddle is a row of twines, cords, or wires called leashes, which are stretched vertically between two horizontal bars or rods, placed about a foot apart. One rod is suspended by a pulley at the top of the loom; and to the lower rod is hitched the foot-treadle. In the middle of each length of twine or wire is the loop or eye, through which a warp-thread is passed. In ordinary weaving there are two heddles, each fastened to a foot-treadle. There is a removable loom attachment which when first shown to me was called a raddle. It is not necessary in weaving, but a convenience and help in preparing to weave. It is a wooden bar with a row of closely set, fine, wooden pegs. This is placed in the loom, and used only during the setting of the warp to keep the warp of proper width; the pegs keep the bouts or sections of the warp disentangled during the "thumbing in" of the threads through the heddle-eyes. This attachment is also called a ravel or raivel; and folk-names for it (not in the dictionary) were wrathe and rake; the latter a very good descriptive title.
