From that day Nat was a changed boy. He would not go to school in the afternoons, but spent the hours from two till five in drawing. I had a cord arranged from our room to Miss Penstock’s, so that he could call her if at any moment he needed help, and she was only too glad to have him in the house. When I reached home at six, I always found him lying back in his chair with his work spread out before him, and such a look of content and joy on his face, that more than once it made me cry instead of speaking when I bent over to kiss him.
