Beauty, after all, is wholly a matter of the nearest possible approach to the physical perfection that many centuries of human faces have established as a standard. Thus perfection in this case does not mean some ideal that has been imaged by a poet, but just the nearest approach to the perfect physical body that nature intended, and which is the flawless example of the type that composes the race. Thus a typical feature is the most beautiful, and by this reasoning a composite picture of all the young girl faces in the Anglo-Saxon nations would be the most beautiful face that any painter could conceive. It follows that health is above all the most essential quality to beauty, because disease, from the nature of things, means thwarted growth that could not possibly reach the typical of the race.

The girl who stood in the moonlight had health. She was simply vibrant with health. It brought a light to her eyes, and a color to her cheeks, and life and shimmer to her moonlit hair. It brought curves to her body, and strength and firmness to her limbs, and the grace of a deer to her carriage. Whether she had regular features or not Dan would have been unable to state. He didn't even notice. They weren't important when health was present. Yet there was nothing of the coarse or bold or voluptuous about her. She was just a slender girl, perhaps twenty years of age, and weighing even less than the figure occasionally to be read in the health magazines for girls of her height. And she was fresh and cool beyond all words to tell.

And Dan had no delusions about her attitude toward him. For a long instant she turned her keen, young eyes to his white, thin face; and at once it became abundantly evident that beyond a few girlish speculations she felt no interest in him. After a single moment of rather strained, polite conversation with Dan—just enough to satisfy her idea of the conventions—she began a thrilling girlhood tale to her father. And she was still telling it when they reached the house.

Dan held a chair for her in front of the fireplace, and she took it with entire naturalness. He was careful to put it where the firelight was at its height. He wanted to see its effect on the flushed cheeks, the soft dark hair. And then, standing in the shadows, he simply watched her. With the eye of an artist he delighted in her gestures, her rippling enthusiasm, her utter, irrepressible girlishness that all of Time had not years enough to kill.

He decided that she had gray eyes. Gray eyes seemed to be characteristic of the mountain people. Sometimes, when the shadows fell across them, they looked very dark, as if the pines had been reflected in them all day and the image had not yet faded out. But in an instant the shadow flicked away and left only light,—light that danced and light that laughed and light that went into him and did all manner of things to his spirit.

Bill stood watching her, his hands deep in his pockets, evidently a companion of the best. Her father gazed at her with amused tolerance. And Dan,—he didn't know in just what way he did look at her. And he didn't have time to decide. In less than fifteen minutes, and wholly without warning, she sprang up from her chair and started toward the door.

"Good Lord!" Dan breathed. "If you make such sudden motions as that I'll have heart failure. Where are you going now?"

"Back to my watch," she answered, her tone wholly lacking the personal note which men have learned to expect in the voices of women. And an instant later the three of them saw her retreating shadow as she vanished among the pines.

Dan had to be helped to bed. The long ride had been too hard on his shattered lungs; and nerves and body collapsed an instant after the door was closed behind the departing girl. He laughed weakly and begged their pardon; and the two men were really very gentle. They told him it was their own fault for permitting him to overdo. Lennox himself blew out the candle in the big, cold bedroom.

Dan saw the door close behind him, and he had an instant's glimpse of the long sweep of moonlit ridge that stretched beneath the window. Then, all at once, seemingly without warning, it simply blinked out. Not until the next morning did he really know why. Insomnia was an old acquaintance of Dan's, and he had expected to have some trouble in getting to sleep. His only real trouble was waking up again when Lennox called him to breakfast. He couldn't believe that the light at his window shade was really that of morning.
