As mile after mile passed in steady, relentless succession, and the hours went by with no relief from the monotonous pound and swing of the horses’ feet, Hugh Edwards found reason to be grateful for the past months of heavy labor that had toughened his muscles and hardened his body for this test of physical endurance. The sun rode in a sky that held no relieving cloud. In the wide basin, rimmed by desert mountains where no trees grew, there was not a shadow to rest his aching eyes. The smell of the sweating horses and the odor of warm, wet saddle leather was in every breath he drew. His lips were parched and cracked, his eyes smarted, his skin was grimy with dust, his clothing damp and sticky with perspiration. He felt that he had been riding for ages. He grimly set his will to ride on and on and on.

It was late in the afternoon when Natachee turned aside from the trail and rode toward a little desert hill near-by. When Edwards, following, asked the reason, Natachee answered:

At every opportunity he ascended some high point from which he could survey the country into which the trail was leading them. After two hours of this they were rewarded by the sight of a small adobe house and corral, a mile, perhaps, from where they stood.

As Natachee pointed to the place he said:

“That is not Indian. The Papago Reservation line, which follows the international boundary for so many miles, turns north at the foot of the Nariz Hills yonder and then after a few miles turns west again to the Santa Rosa Mountains over there. That little ranch is not on the Indian Reservation. It cannot be far from the border. It looks Mexican, and the outlaw’s trail leads directly toward it.”

At the possibility suggested by the Indian’s words, Hugh Edwards cried:
