"Yes, I have; and bad plumbing is bad for it."

Ann laughed quite blithely at that, and as though finding confidence in the sound of her own laugh, she boldly volunteered a stroke. "I don't know much about plumbing," Katie heard Ann saying. "I suppose perhaps it is bad. But do you care much about plumbing when looking at"—her pause before it might have been one of reverence—"The Madonna of the Chair?"

Katie treated herself to a particularly tender bit of lettuce and secretly hugged herself, Ann, and "Days in Florence." The Madonna of the Chair furnished the frontispiece for that valuable work.

Ann had receded, flushed, her lip trembling a little; Wayne was looking at her thoughtfully—and a little as one might look at the Madonna of the Chair. Katie heard the trump of duty call her to another story.

"But morning is the time for letter writing," urged Wayne.

"Morning in this instance is the time for shopping," said Kate.
