The silk which the worm has spun is as fine as the web of a spiderbefore it is unwound. The cocoons are assorted, and those of similarcolor are placed together. When this has been done, they are put intotepid water. If the water is too cold, the gum of the cocoon will notsoften enough to permit the fiber to unwind well; and if it is too warm,it will sink to the bottom. Girls who are experts stir the cocoons untilthey soften,

Girls who are experts stir the cocoons untilthey soften, and the end of the fiber is Silk Winding. A number of these delicate silk fibers are put together through aneyelet, and after being crossed and twisted are wound on a reel. Whenthese threads are dried, they cling together, and form a compact fiberof raw silk. From the reels, this silk fiber is wound upon bobbins in such a wajTthat the threads are all in diagonal lines. These bobbins are nextplaced on the spinning-frame and slightly twisted. Then these strandsare cleansed, wound together upon a reel, and twisted into one thread. WORK OF THE FIFTH GRADE. 95 The thread is then reeled into big skeins; and as it is moist, itmust be thoroughly dried, thus making it ready to be sold to manufac-turers by the pound. As these skeins are somewhat stiff, they arewhirled about in hot soap and water to make them flexible. They arethen dried, packed into linen bags, boiled in water, and again silk is now white and soft, and is ready to be sent away to be
