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.
Then the party went across the street to where they did the killing of beef—where every hour they turned four or five hundred cattle into meat. Unlike the place they had left, all this work was done on one floor; and instead of there being one line of carcasses which moved to the workmen, there were fifteen or twenty lines, and the men moved from one to another of these. This made a scene of intense activity, a picture of human power wonderful to watch. It was all in one great room, like a circus amphitheater, with a gallery for visitors running over the center.
Along one side of the room ran a narrow gallery, a few feet from the floor; into which gallery the cattle were driven by men with goads which gave them electric shocks. Once crowded in here, the creatures were prisoned, each in a separate pen, by gates that shut, leaving them no room to turn around; and while they stood bellowing and plunging, over the top of the pen there leaned one of the "knockers," armed with a sledge hammer, and watching for a chance to deal a blow. The room echoed with the thuds in quick succession, and the stamping and kicking of the steers. The instant the animal had fallen, the "knocker" passed on to another; while a second man raised a lever, and the side of the pen was raised, and the animal, still kicking and struggling, slid out to the "killing bed." Here a man put shackles about one leg, and pressed another lever, and the body was jerked up into the air. There were fifteen or twenty such pens, and it was a matter of only a couple of minutes to knock fifteen or
