Lesbia's duties were to superintend his toilet, take him for walks, and give him a short daily lesson on the piano.
"You see he's just begun music with Miss Gordon," explained Mrs. Stockton, "and it would be such a pity if he were to forget all he's learnt."
Though Lesbia had instructed the juniors at Kingfield High School in the elements of arithmetic, history, and other subjects, she had never in her life before taught music. She felt decidedly nervous as she led Terry, with newly-washed hands, to the piano.
"He'll tell you what he has to do," volunteered Mrs. Stockton, vanishing gladly from the room.
Terry, whose fingers were still rather damp, opened the instruction book in the middle, and twisted the music-stool round and round with quite unnecessary zeal.
"That's enough. It won't go any higher," commanded Lesbia. "Have you got as far as this duet? All in half a term? I suppose you play the treble part? And Miss Gordon takes the bass?"
Terry nodded. He was staring hard at Lesbia as if evolving an idea. Suddenly he burst out:
"When you talk you keep your nose still, and when Miss Gordon talks hers wobbles about just like my rabbit's when it wants a lettuce."
"'Sh, 'sh! That's nothing to do with music," suppressed Lesbia. "Now we're going to try this duet. I'll play the bass. Are you ready? I shall count a whole bar first. One—two—three—four."
They began, Lesbia playing what was before her, but Terry improvising out of his head. He did it so cleverly that his teacher, a little nervous at reading her own part, did not notice for a bar or two that the thumpings in the treble had nothing to do with the instruction book. She stopped him reproachfully. His blue eyes looked as innocent as a child-cherub's.
