The girl knew now where Old Swallowtail was bound. At the end of this lane lay his five acres of stones, and he was about to visit it. The fact gave her a queer little thrill of the heart, for a dozen strange fancies crossed her mind in rapid succession. If he had really killed Ned Joselyn, it was probable he had buried the man in this neglected place, amongst the rubble of stones. Josie had inspected every foot of ground on the Kenton Place and satisfied herself no grave had been dug there. Indeed, at the time of Joselyn's "disappearance" the ground had been frozen so hard that the old man could not have dug a grave. Perhaps after a night or two he had dragged the corpse here and covered it with stones. It would be a safe hiding-place.

And now regret for his act drove the murderer here night after night to watch over the secret grave.

Or, granting that the supposed crime had not been committed, might not Mr. Cragg have discovered some sort of mineral wealth in his stone-yard, which would account for his paying taxes on the place and visiting it so often? Or did he simply love the solitude of the dreary waste where, safe from prying eyes, he could sit among the rocky boulders and commune with himself beneath the moonlit sky?

Such conjectures as these occupied the girl's mind while she stealthily "shadowed" the old man along the lane. Never once did he look behind him, although she was prepared to dissolve from view instantly, had he done so. And at last the end of the lane was reached and he climbed the rail fence which separated it from the valley of stones.

Josie saw him suddenly pause, motionless, as he clung to the rails. She guessed from his attitude that he was staring straight ahead of him at something that had surprised him. A full minute he remained thus before he let himself down on the other side and disappeared from view.

The girl ran lightly forward and, crouching low, peered through the bars of the fence. Half a dozen paces distant the old man stood among the stones in a silent paroxysm of rage. He waved his long arms in the air, anon clenching his fists and shaking them at some object beyond him. His frail old body fluttered back and forth, right and left, as if he were doing a weird dance among the rocks. The violence of his emotion was something terrible to witness and fairly startled the girl. Had he screamed, or sobbed, or shrieked, or moaned, the scene would have been more bearable, but such excess of silent, intense rage, made her afraid for the first time in her life.

She wanted to run away. At one time she actually turned to fly; but then common sense came to her rescue and she resolved to stay and discover what had affected Old Swallowtail so strongly. From her present position she could see nothing more than a vista of tumbled stones, but rising until her head projected above the topmost rail she presently saw, far across the valley, an automobile, standing silhouetted against the gray background.

The machine was at present vacant. It had been driven in from the other side of the valley, where doubtless there were other lanes corresponding with the one she was in. However, there was no fence on that side to separate the lane from the waste tract, so the machine had been driven as close as possible to the edge of the stones.

Although the automobile was deserted, that was evidently the object which had aroused old Cragg's fury, the object at which he was even yet shaking his clenched fists. Josie wondered and watched. Gradually the paroxysm of wrath diminished. Presently the old man stood as motionless as the stones about him. Five minutes, perhaps, he remained thus, controlling himself by a mighty effort, regaining his capacity to think and reason. Then, to the girl's amazement, he tottered toward a large, shelf-like slab of stone and kneeling down, as before an altar, he bared his head, raised his arms on high and began to pray.

There was no mistaking this attitude. Old Swallowtail was calling on God to support him in this hour of trial. Josie felt something clutching at her heart. Nothing could be more impressive than this scene—this silent but earnest appeal to the Most High by the man whom she suspected of murder—of crimes even more terrible. She could see his eyes, pleading and sincere, turned upward; could see his gray hair flutter in the breeze; could see his lips move, though they uttered no sound. And after he had poured out his heart to his Maker he extended his arms upon the slab, rested his head upon them and again became motionless.
