The old man rarely had to criticise Margaret's work. The suggestions made to her came oftener from the students than from the professor himself or any one of the visiting critics. In these criticisms, not only of her own work but of the others, everyone took part, each leaving his stool and helping in the discussion, when the work of the night was over. Fred's more correct eye, for instance, would be invaluable to Jack Bedford, the ex-sign-painter, who was struggling with the profile of the Gladiator; or Margaret, who could detect at a glance the faintest departure from the lines of the original, would shorten a curve on Oliver's drawing, or he in turn would advise her about the depth of a shadow or the spot for a high light. As the nights went by and Oliver studied her the closer, the New England girl became all the more inexplicable to him. She was, he could not but admit, like no other woman he had ever met; certainly not in his present surroundings. She really seemed to belong to some fabled race--one of the Amazons, or Rhine maidens, or Norse queens for whom knights couched their lances. It was useless to compare her to any one of the girls about Kennedy Square, for she had nothing in common with any one of them. Was it because she was unhappy among her own people that she had thus exiled herself from her home, or had some love-affair blighted her life? Or could it be, as Fred had suggested, that she was willing to undergo all these discomforts and privations simply for love of her art? As this possible solution of the vexing problem became established in his mind, with the vision of Margaret herself before him, the blood mounted to his cheeks and an uncontrollable thrill of enthusiasm swept over him. He could forgive her anything if this last motive had really controlled and shaped her life. Had he seen the more closely and with prophetic vision, he would have discerned, in this Norse queen with the golden hair, the mother of a long line of daughters, who, in the days to follow, would hang their triumphant shields beside those of their brothers, winning equal recognition in salon and gallery and conferring equal honor on their country. But Oliver's vision was no keener than that of anyone else about him. It was only the turn of Margaret's head that caught the young student's eye and the wealth of her brown-gold hair. With the future he had no concern.
