From the cabin came the sound of a laugh. It was Longstreet's, and it was like a pleased child's. Chapter XX Two Friends and a Girl Howard and Carr rode down into the darkening valley side by side. The silence of the coming dusk was no deeper than that silence which had crept about them while the three stood upon the cliff's edge. Longstreet's laugh had whipped up the colour into Helen's cheeks and had lighted a battle fire in her eyes. She had whisked away from them and gone straight back to the cabin, meaning to save her father from his own artlessness and from the snare of a designing widow. She had remembered to call out a breathless 'Good-night' without turning her head. They had taken their dismissal together, understanding Helen's tortured mood. Each man grave and taciturn, like two automatons they buckled on their spurs, mounted and reined toward the trail. Then Howard had said merely: 'Come down to the ranch-house, John. I want to talk with you.' And Carr had nodded and acquiesced. Thereafter they were silent again for a long time. The coming of night is a time of vague veilings, of grotesque transformations, of remoulding and steeping in new dyes.

Once Howard, the lighter spirited of the two, sought to laugh the constraint away.
