"You must be pretty heavy, Red," Leaver said considering his host. "Not a particle of superfluous fat, but good, solid structure, I should say. One wouldn't want to try to pass you against your will, in a narrow alley, on a dark night."

"It strikes me you could glide by me in the shadow and never attract my attention," Burns replied, his keen eyes on his friend's face. "The difference between us is that every inch of you represents concentrated energy, while my plant spreads all over the landscape without producing half as much power."

Leaver smiled. There was both strength and sweetness in his smile, but there was depression in it also. "That sounds like you," he said. "I suppose many men envy other men the possession of some supposed source of efficiency. Just now I find myself envying you your home—and its occupants. What a delightful room."

He turned to his hostess and her friend. While they talked together Burns regarded Amy Mathewson, his long-time associate, with renewed wonder, and presently found himself addressing her from an entirely new point of view. This fair girl with the graceful head and the glowing blue eyes could not possibly be the sedate young woman who was accustomed to hand him instruments and sutures, ligate arteries, and attend to various minor matters from the other side of his operating-table. He wondered why he had never before noticed how much real individuality she possessed, nor how really attractive she was of face and person. He decided afresh that his wife was the most wonderful woman in the world, to be able to see at a glance that which had escaped his attention for so long, and he congratulated Miss Mathewson, in his mind, on the possibilities he for the first time saw ahead of her. Clearly after all she was a woman, not a machine!

The party went out to dinner, and Burns looked to see his friend enjoy, as he thought he must, the cleverly planned and deliciously cooked meal which came, perfectly served, upon the table. It was such a dinner as he himself delighted in, unostentatious but satisfying, with certain touches, here and there, calculated to tempt the most capricious palate,—such as he shrewdly judged Leaver, in his presumably lowered state of vitality, to possess.

But to his surprise and dismay the guest barely touched most of the dishes, and ate so sparingly of others that Burns felt himself, with his hearty, normal appetite, a gormandizer. Nobody made any comment whatever upon Dr. Leaver's lack of appetite, but all three noted, with growing concern, that there were moments when he seemed to keep up with an effort. Instinctively the others made short work of the later courses, and felt a decided relief when it became possible to leave the table and return to the living-room.

By a bit of clever management Ellen was able to put the guest's tall form into a corner of the big davenport, among the blue pillows, where he could receive more support than was possible in any other place. After a little he seemed less fatigued, and charmed them all with his pleasant discourse. Burns himself was soon summoned to the office. He would not allow Miss Mathewson to take up her duties there, though she followed him to offer eagerly to run home and change her attire.

"Not a bit of it," Burns assured her, in the hall. He regarded her with mischief in his eyes. "Cinderella isn't due at home till the clock strikes twelve," he whispered. "Besides,—the Prince isn't in his usual form to-night. He may need her services as nurse at any minute, judging by his appearance."

That sent her back into the room, as he knew it would. It was, for her, a wonderfully interesting hour which followed, for Dr. Leaver and Mrs. Burns fell to discussing life in a certain great city, as both knew it from quite different standpoints, and she herself had only to listen and observe. She thought the pair upon the davenport made a striking picture, the woman in her rich and still youthful beauty, her smile a thing to wonder at, her voice low music to the ear; the man, though no older than Burns, worn and grave, yet with a strangely winning personality, and eyes which seemed to see far beneath the surface. In all Amy Mathewson's experience with the men of Burns's profession, she had never met just such a one as John Leaver. The sense of his personal worth and dignity was strong upon her as she watched him; his evident fatigue and weakness appealed to her sympathies; and she forgot herself more completely than she had imagined she could when first summoned to the unaccustomed part she was this evening playing.

But, quite suddenly, the scene changed. In the act of speaking Dr. Leaver suddenly stopped, put one hand to his side, and lay back against the high end of the davenport, breathing short, his face turning pallid, ashen. Ellen rose to her feet in dismay, but Amy Mathewson sprang toward him, drew him with strong arms gently down to a position more nearly recumbent, and with fingers on his pulse said in a low voice, "Call the Doctor, please."
