It had strayed, perhaps. A calf could not be depended upon to remain very long beside its dead mother, though he had known cases where they had. But if it had strayed it could not be very far away. He remounted his pony and loped down the gully, reaching the ridge presently and riding along this, searching the surrounding country with keen glances. He could see no signs of the calf. He came to a shelf-rock presently, beside which grew a tangled gnarl of scrub-oak brush. Something lay in the soft sand and he dismounted quickly and picked up a leather tobacco pouch. He examined this carefully. There were no marks on it to tell who might be the owner.
"A man who loses his tobacco in this country is mighty careless," he observed, smiling; "or in pretty much of a hurry."
He went close to the thicket, looking down at it, searching the sand with interest. Presently he made out the impression of a foot in a soft spot and, looking further, saw two furrows that might have been made by a man kneeling. He knelt in the furrows himself and with one hand parted the brush. He smiled grimly as, peering into the gully, he saw the dead Two Diamond cow on the opposite side.
He stepped abruptly away from the thicket and looked about him. A few yards back there was a deep depression in the ridge, fringed with a growth of nondescript weed. He approached this and peered into it. Quite recently a horse had been there. He could plainly see the hoof-prints-where the animal had pawed impatiently. He returned to the thicket, convinced.
"Some one was here yesterday when I was down there lookin' at that cow," he decided. "They was watchin' me. That man I seen ridin' that other ridge was with the one who was here. Now why didn't this man slope too?"
He stood erect, looking about him. Then he smiled.
"Why, it's awful plain," he said. "The man who was on this ridge was watchin'. He heard my gun go off, when I shot that snake. I reckon he figgered that if he tried to ride away on this ridge whoever'd done the shootin' would see him. An' so he didn't go. He stayed right here an' watched me when I rode up." He smiled. "There ain't no use lookin' for that dogie. The man that stayed here has run him off."
There was nothing left for Ferguson to do. He mounted and rode slowly along the ridge, examining the tobacco pouch. And then suddenly he discovered something that brought an interested light to his eyes. Beneath the greasy dirt on the leather he could make out the faint outlines of two letters. Time had almost obliterated these, but by moistening his fingers and rubbing the dirt from the leather he was able to trace them. They had been burned in, probably branded with a miniature iron.
"D. L," he spelled.
He rode on again, his lips straightening into serious lines.
He mentally catalogued the names he had heard since coming to the Two Diamond. None answered for the initials "D. L." It was evident that the pouch could belong to no one but Dave Leviatt. In that case what had Leviatt been doing on the ridge? Why, he had been watching the rustler, of course. In that case the man must be known to him. But what had become of the dogie? What would have been Leviatt's duty, after the departure of the rustlers? Obviously to drive the calf to the herd and report the occurrence to the manager.
Leviatt may have driven the calf to the herd, but assuredly he had not reported the occurrence to the manager, for he had not been in to the ranchhouse. Why not?
Ferguson pondered long over this, while his pony traveled the river trail toward the ranchhouse. Finally he smiled. Of course, if the man on the ridge had been Leviatt, he must have been there still when Ferguson came up, or he would not have been there to drive the Two Diamond calf to the herd after Ferguson had departed. In that case he must have seen Ferguson, and must be waiting for the latter to make the report to the manager. But what motive would he have in this?
Here was more mystery. Ferguson might have
