“The boys have been working on the slide all day,” Rosie said. “Did you ever see such a nice one, Maida?”

“I never saw any kind of a one,” Maida confessed. “How did they make it so smooth?”

“Pouring water on it.”

“Have you never coasted before, Maida?” Billy asked.

“Never.”

“Well, here’s your chance then,” said a cheerful voice back of them. They all turned. There stood Arthur Duncan with what Maida soon learned was a “double-runner.”

Billy examined it carefully. “Did you make it, Arthur?”

“Yes.”

“Pretty good piece of work,” Billy commented. “Want to try it, Maida?”

“I’m crazy to!”
