“Pard, you--stuck--to me!” the outlaw whispered. Duane caught a hint of gladness in the voice; he traced a faint surprise in the haggard face. Stevens seemed like a little child. To Duane the moment was sad, elemental, big, with a burden of mystery he could not understand. Duane buried him in a shallow arroyo and heaped up a pile of stones to mark the grave. That done, he saddled his comrade's horse, hung the weapons over the pommel; and, mounting his own steed, he rode down the trail in the gathering twilight. CHAPTER IV Two days later, about the middle of the forenoon, Duane dragged the two horses up the last ascent of an exceedingly rough trail and found himself on top of the Rim Rock, with a beautiful green valley at his feet, the yellow, sluggish Rio Grande shining in the sun, and the great, wild, mountainous barren of Mexico stretching to the south. Duane had not fallen in with any travelers. He had taken the likeliest-looking trail he had come across. Where it had led him he had not the slightest idea, except that here was the river, and probably the inclosed valley was the retreat of some famous outlaw. No wonder outlaws were safe in that wild refuge! Duane had spent the last two days climbing the roughest and most difficult trail he had ever seen. From the looks of the descent he imagined the worst part of his travel was yet to come. Not improbably it was two thousand feet down to the river. The wedge-shaped valley, green with alfalfa and cottonwood, and nestling down amid the bare walls of yellow rock, was a delight and a relief to his tired eyes. Eager to get down to a level and to find a place to rest, Duane began the descent. The trail proved to be the kind that could not be descended slowly. He kept dodging rocks which his horses loosed behind him. And in a short time he reached the valley, entering at the apex of the wedge. A stream of clear water tumbled out of the rocks here, and most of it ran into irrigation-ditches. His horses drank thirstily. And he drank with that fullness and gratefulness common to the desert traveler finding sweet water. Then he mounted and rode down the valley wondering what would be his reception. The valley was much larger than it had appeared from the high elevation. Well watered, green with grass and tree, and farmed evidently by good hands, it gave Duane a considerable surprise. Horses and cattle were everywhere. Every clump of cottonwoods surrounded a small adobe house. Duane saw Mexicans working in the fields and horsemen going to and fro. Presently he passed a house bigger than the others with a porch attached. A woman, young and pretty he thought, watched him from a door. No one else appeared to notice him.
