The wages of the spinners are regulated by the fineness of the yarn; that is, by the number of skains, or rather knots, which they spin from the pound of wool. Each knot is composed of 100 threads, and each thread, or turn of the reel, is two Bavarian yards in length; and to prevent frauds in reeling, clock-reels, proved and sealed, are furnished by the establishment to all the spinners. It is possible, however, notwithstanding this precaution, for the spinners to commit frauds, by binding up knots containing a smaller number of threads than 100.--It is true they have little temptation to do so, for as their wages are in fact paid by the WEIGHT of the yarn delivered, and the number of knots serving merely to determine the price BY THE POUND which they have a right to receive, and advantages they can derive from frauds committed in reeling are very trifling indeed. But trifling as they are, such frauds would no doubt sometimes be committed, were it not known that it is absolutely IMPOSSIBLE for them to escape detection. Not only the clerk of the spinners examines the yarn when he receives it, and counts the threads in any of the knots which appear to be too small, but the name of the spinner, with a note of the quantity of knots, accompanies the yarn into the store-room, as was before observed, and from thence to the spooler, by whom it is wound off; any frauds committed in reeling cannot fail to be brought home to the spinner. The bundles of carded wool delivered to the spinners, though they are called pounds, are not exact pounds. They contain each as much more than a pound, as is necessary, allowing for wastage in spinning, in order that the yarn when spun may weigh a pound. If the yarn is found to be wanting in weight, a proportional deduction is made from the wages of the spinner; which deduction, to prevent frauds, amounts to a trifle more than the value of the yarn which is wanting. Frauds in weaving are prevented by delivering the yarn to the weavers by weight, and receiving the cloth by weight from the loom. In the other operations of the manufactures, such as fulling, shearing, pressing, etc. no frauds are to be apprehended. Similar precautions are taken to prevent frauds in the linen;-- cotton;--and other manufactures carried on in the house; and so effectual are the means adopted, that during more than five years since the establishment was instituted, no one fraud of the least consequence has been discovered; the evident impossibility of escaping detection in those practices, having prevented the attempt.
