COTTON YARN MANUFACTURE The chief advantage of school training in this subject does notlie in the actual operation of machines, but rather in the knowledgeof how to adjust the parts of the machines to suit varying conditionsnecessitated by different lengths of fibre and counts of 3arn, in orderthat the machines may be run to the best advantage. The use andstructure of each portion of the machines is studied in its relation to - _ - . .... 47. REGULAR COURSE—SECOND YEAR the other parts with reference to its effect on the product. Startingwith the desire to prcuUice a certain yarn, all the necessary calcula-tions of speed and delivery- arc made, so that the proper amount ofwork may be done at each operation and the tibre handled with theleast amount of injury and waste. The knowledge of how to blendfibres and produce yarns makes the person who is also familiar withdesigning and weaving exceptionally valuable, either as designer, asoverseer of weaving or of carding and spinning, or in those positionsin wdiich men are expected to superintend all three of these opera-tions. The following is an outline of the scope of the subject: \arieties of Cotton.—Their characteristics and uses.—The adaptation ofvarious cottons to different classes of work. FrEpar.\Tory Processes.—Bale breakers.— lattices.—Openers.—In-termediate and finisher pickers. Carding.—The theory of carding ca
