"Go ahead, two Eagles of the Pass," came from the invisible rock aperture, and the party proceeded.
A few paces brought them from under the shadow of the weighted platform and to the foot of the flight of stone steps. A shaggy-headed man emerged from the stable door as they rode up, and took the horses of the new arrivals. He gazed curiously at Nat, but said nothing. Evidently, thought the lad, the colonel is a strict disciplinarian.
This was indeed the case. Col. Morello exacted implicit obedience from his band, which at this time numbered some twenty men of various nationalities. On more than one occasion prompt death had been the result of even a suspicion of a mutinous spirit.
With Manuello still leading him along, as if he were a calf or a sheep, Nat was conducted up the stone staircase and into the rock dwelling itself. The contrast inside the place with the heated air outside was extraordinary. It was like entering a cool cellar on a hot summer's day.
The passage which opened from the door in the cliff was in much the same condition as it had been when the vanished race occupied the place. In the floor were numerous holes where spears had been sharpened or corn ground. Rude carvings of men on horseback, or warring with strange beasts covered the walls. Light filtered in from a hole in the rock ceiling, fully twenty feet above the floor of the place. Several small doors opened off the main passage, and into one of these the colonel, who was in the lead, presently turned, followed by Manuello leading the captive lad.
Nat found himself in a chamber which, if it had not been for the rough walls of the same flame-tinted rock as the abyss, might have been the living room of any well-to-do rancher. Skins and heads of various wild beasts ornamented the walls. On the floor bright rugs of sharply contrasting hues were laid. In a polished oak gun-case in one corner were several firearms of the very latest pattern and design. A rough bookshelf held some volumes which showed evidences of having been well thumbed. From the ceiling hung a shaded silver lamp, of course unlighted, as plenty of light streamed into the place from the window in the cliff face.
The three chairs and the massive table which occupied the centre of the place were of rough-hewn wood, showing the marks of the axe, but of skilled and substantial workmanship, nevertheless. The upholstery was of deerskin, carefully affixed with brass-headed nails.
The colonel threw himself into one of the chairs and rolled a fresh cigarette, before he spoke a word. When he did, Nat was astonished, but not so much as to be startled out of his composure.
"I've heard about you from Hale Bradford," said the outlaw, "and I have always been curious to see you."
