Shif'less Sol soon fell asleep, as Henry, only three feet away, knew by his soft and regular breathing, but the boy himself was still wide-eyed.
The darkness seemed to sink down like a great blanket dropping slowly, and the area of Henry's vision narrowed to a small circle. Within this area the distinctive object was the figure of Tom Ross, sitting with his rifle across his knees. Tom had an infinite capacity for immobility. Henry had never seen another man, not even an Indian, who could remain so long in one position contented and happy. He believed that the silent one could sit as he was all night.
His surmise about Tom began to have a kind of fascination for him. Would he remain absolutely still? He would certainly shift an arm or a leg. Henry's interest in the question kept him awake. He turned silently on the other side, but, no matter how intently he studied the sitting figure of his comrade, he could not see it stir. He did not know how long he had been awake, trying thus to decide a question that should be of no importance at such a time. Although unable to sleep, he fell into a dreamy condition, and continued vaguely to watch the rigid and silent sentinel.
He suddenly saw Tom stir, and he came from his state of languor. The exciting question was solved at last. The man would not sit all night absolutely immovable. There could be no doubt of the fact that he had raised an arm, and that his figure had straightened. Then he stood up, full height, remained motionless for perhaps ten seconds, and then suddenly glided away among the bushes.
Henry knew what this meant. Tom had heard something moving in the thickets, and, like a good sentinel, he had gone to investigate. A rabbit, doubtless, or perhaps a sneaking raccoon. Henry rose to a sitting position, and drew his own rifle across his knees. He would watch while Tom was gone, and then lie would sink quietly back, not letting his comrade know that lie had taken his place.
The faintest of winds began to stir among the thickets. Light clouds drifted before the moon. Henry, sitting with his rifle across his knees, and Shif'less Sol, asleep in the shadows, were invisible, but Henry saw beyond the circle of darkness that enveloped them into the grayish light that fell over the bushes. He marked the particular point at which he expected Tom Ross to appear, a slight opening that held out invitation for the passage of a man.
He waited a long time, ten minutes, twenty, a half hour, and the sentinel did not return. Henry came abruptly out of his dreamy state. He felt with all the terrible thrill of certainty that what happened to Long Jim and Paul had happened also to Silent Tom Ross. He stood erect, a tense, tall figure, alarmed, but not afraid. His eyes searched the thickets, but saw nothing. The slight movement of the bushes was made by the wind, and no other sound reached his ears.
But he might be mistaken after all! The most convincing premonitions were sometimes wrong! He would give Tom ten minutes more, and he sank down in a crouching position, where he would offer the least target for the eye.
The appointed time passed, and neither sight nor sound revealed any sign of Tom Ross. Then Henry awakened Shif'less Sol, and whispered to him all that he had seen.
“Whatever took Jim and Paul has took him,” whispered the shiftless one at once.
