"An' pay the same for half an hour's headache that we could get a whole night's dancin' for?" "I've got to be walking the picket-line all day to-morrow." "Yes, an' I have to be standin' behind a counter. You haven't got nothin' on me there. Get your wraps together now an' come ahead, Carrie. I hear there's a new place opened on Grand Street." Carrie knew how to dance--the poorest girl on the East Side knows that, because not to dance is to miss the one amusement obtainable by the very poor--and, like Katie, she was of that relatively small army that can frequent the dance-halls for perhaps as much as a year without contamination. Before she had taken her course at the night-school, she had even danced in the rooms that the Hebrew politicians provide behind their saloons near Houston Street, where she had seen cadets successfully ply their trade among bland-faced immigrant girls whose very language was unknown to them; and she was therefore wholly prepared for the picture that she confronted when, Katie having paid her ten cents for the two admissions, they entered the low-ceilinged basement of a saloon and tenement-house, and came upon the meeting-place of the Danny Delancy Social Club. Through a veil of dust raised by stamping feet and swirling skirts, through a cloud of heat from a room with every window closed, through a blast of odors compounded of the fumes of alcohol, the scent of tobacco, and the miasma of sweating men and women, there rose, from somewhere, the cries of a beaten piano, struck and thumped into a shrieking likeness to the "Chocolate Soldier" waltz, which only now and then was made at all audible above the rhythmic hubbub. Although the evenings of Saturdays and Sundays were the most popular for dancing, the floor was so crowded that only the expertness of these trained dancers prevented collision and panic. The steam from the bodies of the performers joined with the dry dust in half obscuring the blue-burning gas. The strident laughter of the patrons helped the scraping of their feet in subduing the sounds of the piano. The men gyrated grimly in wet shirt-sleeves, and the women, affecting the most somber shades chosen for the longest wear, spun in their partners' arms with stolid, gum-grinding jaws and lips that were mirthless. Except for the youthful "spielers" admitted without charge, or even hired, to dance with the awkward or make wall-flowers sufficiently happy to insure their return, there were but two types of men among the patrons. There was the native of the quarter, heavy-faced, large-muscled, quick to anger and ready with the fists, a hard-drinking, hard-living sort, no more careful of his neighbor's morals than of his own, yet good-natured, easy-going, pliable. And winding in and out among these, slow and suave, like some sleek species of vulture, were the young men that came there not for pleasure, but for profit, always-smiling young men with manners
