"Come on, fellows!" Jack tried to call to his chums, but his mouth was stopped for an instant by the soft rolls. Besides, there was no need for his invitation, since Ed and Walter, whether they wanted to or not, found themselves being drawn in with irresistible force. By this time the girls had run up, not without some little alarm, and they saw the boys come through the rolls. "Oh--they--they're all--all right," gasped Belle, her hand on her heart. "Of course," cried Jack, with a laugh. "We're most done, ladies. Then it will be your turn." "Never!" declared Cora. "Oh, you'll like it, ladies," the attendant assured them. "Next comes the blueing water," and Jack and his friends, together with a number of other persons who were undertaking the ordeal, were once more on a moving sidewalk, sliding up and down, from side to side, and over a mass of blue, rushing water, which, seen through the sections of the walk, looked as if, every minute, it would surge up all about their feet. But they were as dry as the proverbial bone. "Now if you will kindly step this way you will be hung out to dry," called the attendant, and a door opened, and the boys with several others were fairly shot out into a yard, where they saw what they supposed were persons hanging over clothes lines. Jack recoiled at this. "Go ahead. Be a sport," urged Ed. Then Walter burst into a laugh. "Why, they're dummies!" he gasped. "Straw figures!" And so they proved. "All over!" announced a man. "Have another wash. It will do you good." "Not for mine," declared Jack. "I'm clean enough to last a month." "I'm going to have some more," announced Walter. "So am I," declared Ed. "I'll go through with the girls this time." "And there's Paul yet to be initiated," added Walter. They hurried back to where they had left their friends. "The greatest ever!" declared Jack. "I wouldn't have missed it for anything. Go ahead, girls. It's the greatest fun!" "But those wringers?" faltered Bess. "Aren't you pressed flat?" "Try it--and see," replied Jack, all unconscious of the joke he was perpetrating at the expense of the plump girl. "Were they rubber?" asked Belle. "Go through and see," was all Jack would answer. "I'll try it," volunteered Paul. "So will I," added Cora bravely. "Oh, don't!" begged Belle. "Of course I will. I'm not afraid, after Ed, Walter and Jack have been through it. Besides, look at all the other girls and ladies who venture in." "That's the way to talk," said the attendant admiringly. "In you go, young lady," and he assisted Cora upon the narrow footpath of the first "tub." Cora went through it all, with Paul close behind her. It was all perfectly proper, and not too rough, and the girl thoroughly enjoyed it, even to the two rolling machines. She came back with her cheeks flushed from the exercise and excitement. "Go ahead, girls!" urged Cora to her chums. "It is a most novel experience." "I would, only for the wringers," agreed Bess.
