At first, after leaving the old road, the trail led them straight west, but just before they crossed the Bankhead Highway they turned a little to the south, so as to pass the southern end of the Tortollita range. And here in the harder ground, and among the rocks, the trail became more difficult. Also, as Natachee had foreseen, the outlaw had separated his party; sending the Lizard with the pack mule one way while he with Marta went another. The Indian, explaining to Edwards what had happened, held to Nugget’s tracks.
And now, as he proceeded, the outlaw had taken every precaution to throw any possible pursuer off his trail. Choosing the hardest ground, he had turned and twisted, doubled back and forth, riding over ledges of rock, avoiding soft spots of ground, and taking advantage of everything in his course that would be an obstacle in the way of any one attempting to follow. At the same time, he had moved steadily toward the west and south.
Edwards, in dismay, felt that all hope of rescuing Marta was lost. To his eyes there was no mark to show which way they had gone. But Natachee smiled.
Dismounting, and giving his bridle rein to his companion, the Indian went ahead, stooping low at times and moving slowly, again running confidently at a dog trot. Three times he caused Edwards to wait while he drew a wide circle and picked up the trail at some point further on. Where Hugh could see not the slightest mark to show that a living thing had passed that way, the Indian moved forward with a certainty that was, to the white man, almost supernatural. A tiny scratch on a rock, a pebble brushed from its resting place, was enough to mark the way for the Indian as clearly as if it were a paved street. It was late in the afternoon when the trail finally drew away from the Tortollitas and again lay clearly marked in the softer ground of the desert. And here, presently, Natachee pointed out to Edwards that the tracks of the Lizard’s horse and the pack mule had again merged with those of the animals ridden by Sonora Jack and his captive.
The sun had set when Natachee stopped his horse. There was still light to see the trail but it would last but a few minutes longer. For some time the Indian seemed lost in contemplation of the scene. Slowly his eyes swept the vast reaches of desert and the mountain ranges that lay before them. His companion waited.
At last Natachee said:
“Sonora Jack is going to Mexico. If he were not, he would have gone to the north of the Tortollitas back there. But Mexico lies there to the south and this trail is leading almost due west.”
“What can we do?” cried Edwards. “It will be dark in twenty minutes, we cannot follow the trail in the night.”
“Patience,” returned the Indian, “and listen. The ways by which one may go through these deserts and mountains are more or less fixed.” Pointing to the southwest where the ragged sky-line of the Tucson range was sharp against the glowing sky, he continued:
“The outlaw would not risk going straight south on this side of those hills because that is the thickly settled valley of the Santa Cruz with the city of Tucson to bar his way. Do you see, through that gap in the Tucson range, a domelike peak of another range beyond?”
