She went over and picked up the cougar skin and spread it on the earth, showing it from tip to tip. "Mose took him here in the shoulder," she said, "an' his second shot fixed him right atween ther eyes. Measures 'bout nine feet."

But the teacher had turned away. She went back to the cedar stump and stood leaning weakly on it, looking off in the direction of the canyon. It seemed very far off.

Presently Martha joined her. She had prepared a pointed stick by holding it in the fire, and the end of it still smouldered. "I'm goin' down-stream ter dig wapato," she said. "Them two prospectors is goin' ter be terrible hungry when they get back, an' it'll taste pretty good."

Alice had seen this edible root, which is a favorite food among the Indians; it grew in profusion along the watercourse. "I will go with you and help," she said, "unless I had better stay to watch the horses."

Martha stood a thoughtful moment looking at the black. "I dunno," she said, "how Dick Slocum kem to leave Colonel. He hed er mighty good chanct to take er horse that 'ud carry him out er ther country, easy. But he was mighty scared o' makin' er noise, an' got erway in er terrible hurry. I jedge he didn't 'low ther was only one gun in ther crowd; he hedn't located Eben an' ther rifle."

But evidently the outlaw had located the rifle, for, lifting her keen eyes Martha discovered Forrest, the gun in the curve of his arm, coming swiftly down the glade. His glance swept the open anxiously, as he approached, but at sight of the girl, unharmed, the tense lines softened in his face. "I thought I heard a shot," he said, and his look again searched the place for the hunter; "I fixed it at about here. But I see I was mistaken. The truth is," he shook his head, smiling at his folly, "I got it into my head that you needed me. I couldn't think of anything else. You see you were so incautious yesterday, at the river; then, too, I blamed myself for leaving you without the protection of Eben's rifle. And I had forgotten to give you your book. You dropped it yesterday at the canyon, and I was afraid the time would drag without anything to read."

He drew the little volume from his pocket, and flushing, conscious of the shallowness of his excuse, looked off, riverward.

"I jedge," said Martha briefly, "ef you head right off fur ther river, up-stream, you kin hit Dick Slocum's trail. He's jest gone off 'ith ther rations, bag an' all. Keep ther rifle handy; he's took Mose Laramie's gun."

Then for the first time Forrest looked straight at the girl. The line drew black between his brows. He saw that her face was grimy with smoke and moisture; that the hand which had taken the book was scratched, bruised, stained. "Slocum? Then I did hear a shot." His voice was quiet, but it took a new quality, the streak of iron outcropping in the man. "He did not offer to touch you?"

"No, oh, no." She swayed a little on her feet; it was difficult to find words. "The shot you heard was Mose's. He—"
