He remembered that the younger of the two boys had forgotten all but the first of his name.

He had told them that it was John Calvin--something; he could not remember what, so great had been his fright; the people at the ranch, because of his forlorn appearance, had thereupon named him John Calvin Sorrow.
These two boys had watched him closely as he mounted his horse, and the older one had called to him, "When I get to be a man, I'm coming back with a gun and kill you till you are dead yourself," and the other, little John Calvin Sorrow, had clenched his fists and echoed the threat, "We'll come back here and kill you! Mormons is worse'n Indians!" He had ridden quickly away, not noting that some of the men standing by had looked sharply at the boys and then significantly at one another.
One of those who had been present, whom he now met, told him of these two boys.

They tracked him quite a ways when it come light, till his tracks run into the trail of a big band of Navajos that had been up north trading ponies and was going back south.
