"'Dan!' I called, 'don't go near him!'
"I might as well have called out to a whirlwind. He leaped. Black Bart sprang to meet him with eyes green with fear. I heard the loud click of his teeth as he snapped—and missed. Dan swerved to one side and caught Black Bart by the throat and drove him into the dust, falling with him.
"I couldn't move. I was weak with horror. It wasn't a struggle between a man and a beast. It was like a fight between a panther and a wolf. Black Bart was fighting hard but fighting hopelessly. Those hands were settling tighter on his throat. His big red tongue lolled out; his struggles almost ceased. Then Dan happened to glance at me. What he saw in my face sobered him. He got up, lifting the dog with him, and flung away the lifeless weight of Bart. He began to brush the dust from his clothes, looking down as if he were ashamed. He asked me if the dog had hurt me when he snapped. I could not speak for a moment. Then came the most horrible part. Black Bart, who must have been nearly killed, dragged himself to Dan on his belly, choking and whining, and licked the boots of his master!"
"Then you do know what I mean when I say Dan is—different?"
She hesitated and blinked, as if she were shutting her eyes on a fact. "I don't know. I know that he's gentle and kind and loves you more than you love him." Her voice broke a little. "Oh, Dad, you forget the time he sat up with you for five days and nights when you got sick out in the hills, and how he barely managed to get you back to the house alive!"
The old man frowned to conceal how greatly he was moved.
"I haven't forgot nothin', Kate," he said, "an' everything is for his own good. Do you know what I've been tryin' to do all these years?"
"What?"
"I've been tryin' to hide him from himself! Kate, do you remember how I found him?"
"I was too little to know. I've heard you tell a little about it. He was lost on the range. You found him twenty miles south of the house."
