"Since you are so anxious to see our fort I shall gratify your wishes," he said. "Manuello, just take a turn or two about that boy and we'll take him home with us; he'll be better game than that lion yonder."
Manuello nimbly tumbled off his horse, and in a trice had Nat bound with his rawhide lariat. The boy was so securely bundled in it that only his legs could move.
"Good!" approvingly said the colonel as he gazed at the tightly tied captive, "it would be folly to take chances with these slippery Americanos."
Manuello now remounted, and taking a half-hitch with the loose end of his lariat about the saddle horn, he dug his spurs into his pony. The little animal leaped forward, almost jerking Nat from his feet. He only remained upright with an effort.
"Be careful, Manuello," warned the colonel, "he is too valuable a prize to damage."
Every step was painful to Nat, bruised as he was, and weak from hunger and thirst as well, but he pluckily gave no sign. He had deduced from the fresh condition of his captors' ponies that they could not have been ridden far. This argued that it would not be long before they reached the outlaws' fortress.
In this surmise he was correct. The trail, after winding among chaparral and madrone, plunged abruptly down and entered the gloomy defile he had noticed when he first made up his mind that he was lost. Viewed closely the place was even more sinister than it had seemed at a distance. Hardly a tree grew on its rugged sides, which were of a reddish brown rock. It seemed as if they had been, at some remote period, seared with tremendous fires.
The trail itself presently evolved into a sort of gallery, hewn out of the sheer cliff face. The precipice overhung it above, while below was a dark rift that yawned upon unknown depths. So narrow was the pass that a step even an inch or two out of the way would have plunged the one making it over into the profundities of the chasm. A sort of twilight reigned in the narrow gorge, making the surroundings appear even more wild and gloomy. A chill came over Nat as he gazed about him. Do what he would to keep up his spirits they sank to the lowest ebb as he realized that he was being conducted into a place from which escape seemed impossible. Without wings, no living creature could have escaped from that gorge against the will of its lawless inhabitants.
Suddenly, the trail took an abrupt turn, and Nat saw before him the outlaws' fort itself.
