Ascending to the fourth floor, the noisy sound of machinery is first heard. This is the department for sewing straw braid; here unquestionably centres the interest in a hat factory; the hum of a hundred machines quickens the pulse, and to the observer, the interest and astonishment increases as the wonderful machine with its lightning speed, guided by the magic touch of the young woman who rules it, draws towards itself yard after yard of the delicate strand of straw plait which it sews together by the finest stitch of the most slender thread, till suddenly a hat comes forth, complete in its full perfection of shape. One's surprise would not be more greatly heightened by a display of the magician's art. The marvel of this accomplishment may be effectively demonstrated by a simple statement. That bit of mechanism occupying a space of 10 x 12 inches, with its apparently simple arrangement of levers and cogs, merely carrying a needle to and fro, up and down, will do in a single minute the work an industrious woman with her unaided fingers could not do in less than an hour. That little machine is capable of doing within the working hours of a day the labor of sixty women; while a hundred machines in a factory are capable of producing the handwork of six thousand people; this shows the progress of the world, and the advance that has come to this branch of industry within the last thirty years. [Illustration: SEWING DEPARTMENT.] Straw braid preparatory to being sewed is wound upon reels, from which it is easily fed to the sewing machine; this department of winding and reeling is also located upon this floor. Adjoining is the machine room. This department is not only the hospital for invalid and incapacitated machines, where they receive the treatment required to put them in suitable working condition, but its field of usefulness is extended to the making of much of the required machinery, implements and various tools used throughout the establishment.
