Being una-ble to get as much labor as the old system demanded, theplanters began tO manifest a spirit of interest in the introduc-tion of mechanical appliances tending tO reduce the numberof hands necessary for their work. Wooden cogs and wallowers of gin running gear, usedfor transmission of power, and similar machinery, wore rap-idly and required frequent renewal. When these renewalswere made by labor which cost nothing, such machinery wassatisfactory, but when the labor had to be paid for in money,a demand immediately arose for cast bevel wheels. Thisapplication of cast-iron gearing was probably the first movein the direction of labor-saving devices. Wrought band ironreplaced ropes for binding the bales of cotton, both as amatter of economy and for safety from fire. The feeder and the condenser were inventions ofmuch importance; the first was a contrivance into which the .. o HOO QA< A O H OO DEVEI^OPMENT O^ MANUFACTURE:S. i8i seed cotton could be put, and which would, with proper ad-justments, feed the gin; the other attachment caught the lintcotton between two skeleton wire-cloth bound rollers, anddelivered it from the gin in a continuous *bat, instead oflike feathers in a gale. Next came a compact press capableof pressing a bale by the power of two stout laborers. Thenthe steam power began to be used, and instead of everyplanter owning his own gin, the larger ones only owned one,and they ginned for the public. Following these adapta-tions were well-designed modern steam ginneries, equippedwith labor-saving appliances. About 1885, exhaust suctionfans came into use, and they made possible the unloading ofcotton direct from the wagon through a pipe or flue into thegin feeder or into bins partitioned off in the gin, house. These changes may be said tO have forced themselves
