The party descended to the next floor, where the various waste materials were treated. Here came the entrails, to be scraped and washed clean for sausage casings; men and women worked here in the midst of a sickening stench, which caused the visitors to hasten by, gasping. To another room came all the scraps to be"tanked," which meant boiling and pumping off the grease to make soap and lard; below they took out the refuse, and this, too, was a region in which the visitors did not linger. In still other places men were engaged in cutting up the carcasses that had been through the chilling rooms. First there were the "splitters," the most expert workmen in the plant, who earned as high as fifty cents an hour, and did not a thing all day except chop hogs down the middle. Then there were"cleaver men," great giants with muscles of iron; each had two men to attend him—to slide the half carcass in front of him on the table, and hold it while he chopped it, and then turn each piece so that he might chop it once more. His cleaver had a blade about two feet long, and he never made but one cut; he made it so neatly, too, that his implement did not smite through and dull itself—there was just enough force for a perfect cut, and no more. So through various yawning holes there slipped to the floor below—to one room hams, to another forequarters, to another sides of pork.One might go down to this floor and see the pickling rooms, where the hams were put into vats, and the great smoke rooms, with their airtight iron doors.In other rooms they prepared salt pork—there were whole cellars full of it, built up in great towers to the ceiling. In yet other rooms they were putting up meats in boxes and barrels, and wrapping hams and bacon in oiled paper, sealing and labeling and sewing them.From the doors of these rooms went men with loaded trucks, to the platform where freight cars were waiting to be filled; and one went out there and realized with a start that he had come at last to the ground floor of this enormous building.
