This seemed to be Sylvia's last protest against learning for the night, for after this she turned docile, and really took pains to understand all that Philip could teach her, by means of the not unskilful, though rude, map which he drew for her with a piece of charred wood on his aunt's dresser. He had asked his aunt's leave before beginning what Sylvia called his 'dirty work;' but by-and-by even she became a little interested in starting from a great black spot called Monkshaven, and in the shaping of land and sea around that one centre. Sylvia held her round chin in the palms of her hands, supporting her elbows on the dresser; looking down at the progress of the rough drawing in general, but now and then glancing up at him with sudden inquiry. All along he was not so much absorbed in his teaching as to be unconscious of her sweet proximity. She was in her best mood towards him; neither mutinous nor saucy; and he was striving with all his might to retain her interest, speaking better than ever he had done before (such brightness did love call forth!)--understanding what she would care to hear and to know; when, in the middle of an attempt at explaining the cause of the long polar days, of which she had heard from her childhood, he felt that her attention was no longer his; that a discord had come in between their minds; that she had passed out of his power. This certainty of intuition lasted but for an instant; he had no time to wonder or to speculate as to what had affected her so adversely to his wishes before the door opened and Kinraid came in. Then Hepburn knew that she must have heard his coming footsteps, and recognized them. He angrily stiffened himself up into coldness of demeanour. Almost to his surprise, Sylvia's greeting to the new comer was as cold as his own. She stood rather behind him; so perhaps she did not see the hand which Kinraid stretched out towards her, for she did not place her own little palm in it, as she had done to Philip an hour ago. And she hardly spoke, but began to pore over the rough black map, as if seized with strong geographical curiosity, or determined to impress Philip's lesson deep on her memory.
