For the sizing of the warp, the Germans use a paste made of flour, the same as we do. In general they employ _rye flour_ for plain linen, but very carefully sifted. For fancy or damask cloth they use wheat flour. We may again remark that they pay great attention to the sifting, so that no seed may be in the paste. The work-rooms should be suitable to the quality of the work, better lit and consequently more airy. The workmen have every thing to gain in preserving a precious health for their family; a robust man can do more work than an invalid. In Germany the work-rooms contain four looms with ease, and are lit by glass windows the same as the shops in our towns. We remind all that when a work-room is well arranged, and when everything is in its place, the work is done with more perfection, more regularity, and, finally, with more economy. BLEACHING. The Germans pay great attention to the first washing of the linen, in which they use a fluted beetle, fixed so as to rub the cloth, without striking it or bruising it too rudely. They shun all chemical agents, they use water from the purest sources, and constantly renew it. The sizing is effected with a starch, made at Cologne. We brought a sample of it, which we keep for the inspection of all; it is thought to be of a better quality than ours; and I am inclined to believe, that it is to the superior starch that the German linens owe their silky gloss. The drying is effected in lofts, well constructed and spacious, where the cloth is protected as well from the sun as from the rain. They employ rollers for stretching and turning the linen, which make every movement easy. We desire to see our bleachers imitate the Germans in the care which they bestow on the details of the operations which we have just examined. CALENDERING. No one is ignorant that, with us, this process is far from perfect. We must, then, call the attention of those who practice it, to the improvements that their machines call for. On this subject, the Director is ready to communicate all the ideas he has gathered. The calender or mangle which the Germans use, is sixty feet long, eight or nine broad, and fifteen high. A box, filled with stones, supported by two wooden cylinders, of six or seven inches in diameter, is moved backward and forward, alternately, upon a wooden plank, perfectly level; the linen is rolled round the wooden cylinders, and remains there for a quarter of an hour. This system gives a flat finish, the cloth being dry, and passing without heat. At Bielefield there exists another machine, called “the English Beetling Machine,” by which a rounder finish is obtained than by the calender, and which increases, momentarily, at least, the width of the cloth. In this operation, the linen, when dried and folded, is placed on a table of polished stone, and beetled by heavy mallets. ATTENTION PAID TO THE SALE.
