Swept clean in the morning, the floor itself, seen now through the thinning groups, was littered from end to end with scattered grain--oats, wheat, corn, and barley, with wisps of hay, peanut shells, apple parings, and orange peel, with torn newspapers, odds and ends of memoranda, crushed paper darts, and above all with a countless multitude of yellow telegraph forms, thousands upon thousands, crumpled and muddied under the trampling of innumerable feet. It was the debris of the battle-field, the abandoned impedimenta and broken weapons of contending armies, the detritus of conflict, torn, broken, and rent, that at the end of each day's combat encumbered the field. At last even the click of the last of telegraph keys died down. Shouldering themselves into their overcoats, the operators departed, calling back and forth to one another, making "dates," and cracking jokes. Washerwomen appeared with steaming pails, porters pushing great brooms before them began gathering the refuse of the floor into heaps. Between the wheat and corn pits a band of young fellows, some of them absolute boys, appeared. These were the settlement clerks. They carried long account books. It was their duty to get the trades of the day into a "ring"--to trace the course of a lot of wheat which had changed hands perhaps a score of times during the trading--and their calls of "Wheat sold to Teller and West," "May wheat sold to Burbank & Co.," "May oats sold to Matthewson and Knight," "Wheat sold to Gretry, Converse & Co.," began to echo from wall to wall of the almost deserted room. A cat, grey and striped, and wearing a dog collar of nickel and red leather, issued from the coat-room and picked her way across the floor. Evidently she was in a mood of the most ingratiating friendliness, and as one after another of the departing traders spoke to her, raised her tail in the air and arched her back against the legs of the empty chairs. The janitor put in an appearance, lowering the tall colored windows with a long rod. A noise of hammering and the scrape of saws began to issue from a corner where a couple of carpenters tinkered about one of the sample tables. Then at last even the settlement clerks took themselves off. At once there was a great silence, broken only by the harsh rasp of the carpenters' saws and the voice of the janitor exchanging jokes with the washerwomen. The sound of footsteps in distant quarters re-echoed as if in a church. The washerwomen invaded the floor, spreading soapy and steaming water before them. Over by the sample tables a negro porter in shirt-sleeves swept entire bushels of spilled wheat, crushed, broken, and sodden, into his dust pans. The day's campaign was over. It was past two o'clock. On the great dial against the eastern wall the indicator stood--sentinel fashion--at ninety-three. Not till the following morning would the whirlpool, the great central force that spun the Niagara of wheat in its grip, thunder and bellow again.
