He turned to leave it, then came back as if fascinated. Finally he stooped, and with nervous, desperate fingers dragged and tore at the network of dry, tangled fibers that covered the mound. At last he uncovered something that looked and felt like a piece of cloth. But the color of it-the color of it! Out of the dim shadow it gleamed at him, bright, clear, bluest and purest of blues-the hue of a bluebird's wing!

Frantically, with a growing sense of impending horror, Drayton persisted in his task until his worst fears were confirmed.

Beneath that grass lay the body of a woman, face down. Though the face was concealed, he knew her instantly. And she lay there, deathly quiet, face down and the grass had grown over her.

How long-good God! — how long a time had passed since he had stood face to face with this girl in James Burford's library? It had been morning there. Here it was sunset. Sunset? How many suns had set since that grass was young and began its task of shroud weaving?

Conquering a sudden and violent impulse to flee, Drayton turned the body over and laughed a little wildly. After all, the grass was a liar. Dead the girl might be-she lay still enough-but if dead she was most recently so. Her face was pale and sweet and perfect as a child's sleeping there in the shadow. The lids were closed softly over her eyes, as if at any moment the curling lashes might quiver and lift.

Scarcely breathing, Drayton knelt and laid his ear above her heart. Surely that was a faint flutter he felt! Raising her head, he sought some other sign of returning consciousness. There was none. He laid a hand on her forehead. It was cool, but not with the chilling coldness he dreaded.

Questioning no longer, but with a great hope in his heart, Drayton sprang to his feet and paused. Where in this empty, houseless land could he obtain any stimulant or even water to revive her? He must have it-he must save her before that faint trace of life should flicker out. Alone he had been nothing. With this small sister of Trenmore's at his side he could face all the mysteries of the universe with a cheerful carelessness. He loved her suddenly and joyously, not because she was the most beautiful creature he had ever seen, but simply because she was human!

Yet should he leave her to seek water the girl might die in his absence. Better he had never found her than that! Despairing of other means, Drayton was about to try what resuscitation the chafing of wrists and forehead might effect when, glancing westward to judge how much of day might be left him, he beheld an odd, unlooked-for thing.

On the side of the ruins toward the plain stood the longest and highest fragment of the outer wall. On the left it rose in a jagged slant from the old foundations to a height of six or seven feet, extended level for a distance of four yards or so, then ended in an abrupt vertical line that exactly bisected the red sun, now touching the horizon. And from beyond its black silhouette, against the faint pink of the western sky, a thin puff of smoke was ascending!

It was dissipated by the slight breeze from the plain. Another puff and another followed it. Then the puffs ceased, to be succeeded by a slow, thin column of mysterious vapor.
