This vault formed a passage wide enough for four persons to march abreast, and of sufficient height for them not to be obliged to stoop; it rose with a gentle incline, and resembled a species of labyrinth, owing to the constant turns it took. The darkness was complete, but the impulse had been given, and no other noise was audible save that of the panting breathing of these men, and their hurried footsteps, which sounded hollow on the damp ground they trod. After a twenty minutes' march, which seemed to last an age, the Scalper's voice rose in the gloom, and uttered the single word, "Halt!" All stopped. "Here we shall have to make our final arrangements," the Scalper continued; "but in the first place let me procure you a light, so that you may know exactly where you are." The old man, who seemed gifted with the precious privilege of seeing in the darkness, walked about for some minutes in various directions, doubtless collecting the ingredients necessary for the fire he wished to kindle; then he struck a light, lit a piece of tinder, and almost immediately a brilliant flame seemed to leap forth from the ground, and illumined objects sufficiently for them to be distinguished. The Scalper had simply lighted a fire of dry wood, probably prepared beforehand. The Texans looked curiously around them, so soon as their eyes, at first dazzled by the bright flames of the fire, had grown accustomed to the light. They found themselves in a very large, almost circular vault, somewhat resembling a crypt; the walls were lofty, and the roof was rounded in the shape of a dome. The ground was composed of a very fine dry sand, as yellow as gold. This room seemed cut out of the rock, for no sign of masonry was visible. In the background, a staircase of some twenty steps, wide, and without bannister, mounted to the roof, where it terminated, and it was impossible to distinguish whether there were any trapdoor or opening. This trap doubtless existed, but time had covered its openings with the impalpable dust, which it incessantly wears off even the hardest granite. After attentively examining the vault by the aid of a blazing log, the Jaguar returned to the old man, who had remained by the fire. "Where are we?" he asked him. Each curiously extended his ear to hear the Scalper's answer. "We are," he said, "exactly under the patio of the hacienda; this staircase ends in an opening I will point out to you, and which leads into a long-deserted corral, in which, if I am not mistaken, the wood stores of the hacienda are now kept." "Good," the Jaguar answered; "but before venturing into what may be an adroitly laid trap, I should like, myself, to visit the corral of which you speak, in order to see with my own eyes, and assure myself that things are really as you say." "I ask nothing better than to lead you to it."
