Wonderingly, Hugh obeyed.

On the farther side of the ridge lay the body of the Lizard.

Not until the following day did Hugh Edwards understand why the red man’s face was so grim, and why he would not speak of the Lizard’s death.

Hour after hour the Indian and the white man followed the trail that led southward through the Papago country. Natachee set the pace, nor did he once stop or hesitate, for the tracks of the two horses and the pack mule were clear in the soft ground, and the outlaw had made no attempt to confuse possible pursuers.

Skirting the northern end of the Comobabi range, and leaving Indian Oasis well to the east, the trail avoided two small Indian villages that lie at the foot of the Quijotoas and then swung more to the west. Natachee, who for three hours had not spoken, pointed to a group of mountains miles ahead.

“The Santa Rosa and the Nariz Mountains on the Mexican line. Sonora Jack is making for the headquarters of his old outlaw band.”

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:

“We are not far from the border. Sonora Jack must have friends in this neighborhood or he would not have come so far west before crossing into Mexico.”

Dismounting, the two men climbed to the top of the hill, and from that elevation scanned the surrounding country. When Natachee was satisfied, they returned to their horses and rode on. But now the Indian held to the trail only at the intervals necessary to assure himself of the general bearing of the outlaw’s course. 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.
