"And I sat on her," Archie supplemented. "I don't know which of us was the more astonished, she or I. What were you going to do with her?"

"Why, you see," Theodora dropped her books on the seat by the staircase and settled herself beside them; "you see, it was my first experience with slumming."

"With what?"

"Don't you know? Or don't you have any slums in Montana? Everybody does it here, and it's beautiful."

"What's the usual modus operandi?"

"The what? Talk English, please."

"How do you go at it?" Archie sat down on the top step, to talk at his ease.

"Oh, they go to see poor people, and take them food and soap and madonnas and fumigate them."

"The madonnas?"

"No, the people. It does them ever so much good. Mrs. Farrington, Billy's mother, had a friend here that did it, and she told us all about it."
