At a moment in which mill-spun yarn, the rival production to hand-spun yarn, lays claim to a superiority, which it bases upon the uniform equality of its thread, the hand-spinners must strain every nerve to attain this equality. It is essential that they avoid, as much as possible, any knots or lumps in the yarn, that they extract any particles of tow their fingers may meet. We could also recommend that the operation may be conducted with extreme cleanliness, that any stains of oil, coal, &c., be avoided, or anything which may be difficult to remove in the bleaching. The Germans beat their yarn a good deal before weaving it, to render it more soft and supple, they affirm that they thereby improve the quality of the cloth. According to them, the softer and more yielding the yarn, the firmer and more solid will be the cloth when bleached, it has not the disadvantage of being too hard and stiff, and, therefore, fraying at the folds. The system may be the object of experiment. It is, also, useful to prepare the yarn by boiling it in a solution of alkali, and by soaking it in milk. Ashes from beech wood are to be preferred to those from ash. This is at least the result of their experience in Germany. We submit the observation to our merchants and manufacturers, to induce them to make a trial, and to communicate to us afterwards the result. The use of any chemical agent in bleaching must be rigorously abstained from, their use has been constantly prohibited by our ancient laws, and even by royal edicts. WEAVING. The piece of cloth should be throughout uniform in fabric, and in colour. It is then indispensable, as well for the weft as for the warp, to use yarn from the same description of flax. There must be none of those dry and dead fibres, so that they do not disappear in the bleaching. The warp and the weft should be as much as possible each spun from the same specimen.
