“All to the la-la!” added Ed.

“It most——” began Walter, but, at that minute all three came to the end of the first scrubbing process, and were precipitated upon a highly polished slide—somewhat like the bamboo ones that are so popular at summer resorts. It was like glass, and, as there were only a few lights at this point, whereas the “tub” was brilliantly illuminated, the boys went down in a heap, and slid along.

“Part of the game,” commented Jack, grimly.

“You are now on the washing board,” came from the announcer. “Keep perfectly still—there is no danger.”

In front of, and behind, the boys came other persons—slipping, sliding, shouting, yelling, laughing, gasping and struggling.

“Wow!” yelled Ed. “Here comes another tub to go through!”

They had reached the end of the “washboard” and once more the three boys were tossed up and down, and from side to side, while rushing water under them seemed to give the effect of being put through a boiler of suds.

“Look out! Here’s something new!” yelled Ed, a moment later, and, sure enough, they emerged, after a trip up and down, and around corners, upon a scrubbing board, made of glass, under which water was rushing with such effect that it seemed as if they were going to be soaked.

“This is great!” cried Jack, as he reached it. “I thought I was in for it that time, but it’s all to the soap and starch; that’s what!”

His companions, and many others, followed, and, a moment later, they were facing what looked like two rolls, such as collars and cuffs are run through.
