uires three cars to carry the ginnery bales to the compressor, and two cars to carry the compressed bales to the port, warehouse, or mill. The saving in freight and handling is obvious. It needs only a glance at the photograph of the two bales side by side to see the possible saving in waste and "city crop," or tare. The obstacles in the way of such an improvement are those which face any revolutionary change in commercial methods. Established practice, invested capital, and the natural conservatism of human nature militate against quick improvement. CHAPTER VIII In the Cotton Mill The manufacture of cotton cloth may be divided into five departments: 1. Preparatory processes: Opening, carding, combing, and drawing. 2. Spinning. 3. Spooling, warping, sizing, slashing, entering or drawing-in. 4. Weaving. 5. Converting and finishing, including bleaching, mercerizing, dying, printing, and finishing. Before the cotton fiber can be spun into the yarn from which the cloth is woven, the bales must be broken open, the impurities removed, and the fibers arranged so that they are parallel and contain no bunches or tangles. Care in these processes has become more and more necessary and important as the demand for a higher quality of cloth, possessing greater strength and evenness, has been developed. Hence, some of the most elaborate, complex, and admirable machinery in the mill is that devoted to these preparatory processes. The principle involved is always that of thoroughly cleaning the material, then opening it so that every fiber shall be thoroughly separated from its fellows, and then straightening out the fibers, no matter what types of machines may be used. Conveying Fiber By Air Blast The heavy laps of cotton are first thrown directly from the bale into the breaker, and the cotton is then usually blown through large pipes from the room in which the bales are broken to the room in which the openers are located. The functions of the opener are two. The first is to clean from the cotton the dirt and bits of leaf, pod, and foreign substances, which may have clung to the fiber as it passed through the gin back on the plantation. The second is to roll the cotton into a more or less regular "lap," as it is called. The Energetic Opener At Work As the cotton goes into the opener (see diagram on following page), dusty and dirty, it is seized by str
