" Oh, but it wouldn't be a useless walk, sir. Father said nothing was useless that helped to keep us in tune, you know."

"In tune!"

"I mean, you looked as father used to look sometimes, when he felt out of tune. And he always said there was nothing like a walk to put him back again. I—I was feeling a little out of tune myself to-day, and I thought, by the way you looked, that you were, too. So I asked you to go to walk. "
