Bruno Gillespie was only too well assured that this latest fear had foundation on truth. Swiftly though he had wielded the awkward (to him) hand-wood, Huatzin had sufficient time to sight his assailant, and almost certainly had divined at least a portion of the truth. Doubtless it would have been the more prudent course to repeat that blow with greater precision; but Bruno could not bring himself to do just that, even though the ugly cries were growing in volume on the ground level; and he felt that capture would be but the initial step to death, in all likelihood upon the great stone of sacrifice. Imminent though their peril surely was, Bruno could not betake himself to flight without at least partially performing the duty for which he had volunteered; and so he took time to hurriedly utter: “Watch from the top of the tower for the air-ship, and be ready to leave at any moment, I implore you--both!” For even now his admiring gaze could with difficulty be torn away from yonder younger, even more lovely, visage; although as yet the maiden had spoken no word, even shrinking away from this strangely speaking Aztec as though in affright. “Come, brother, or too late,” urged Ixtli, almost sternly. “Save you, or Glass-eyes call Ixtli dog-liar. Come; must run, no fight; too big many for that.” And so it seemed, when the young men rushed away from the lighted interior and gained the uncovered space beyond. Loud cries came soaring through the night from different directions, and dim, phantom-like shapes could be glimpsed in hurrying confusion. Apparently the majority only knew that trouble of some description was brewing, and that the centre of interest was either in or near the Temple of the Sun God; yet that was more than sufficient to place the white intruder in great peril, despite the elaborate disguise he wore. Then with awful abruptness there came a sound which could only be likened to rolling thunder by one uninitiated, but which caused Ixtli to shrink and almost cower, ere gasping: “The great war-drum! Now MUST go! Sacrifice if caught; come, white brother! See, dat more bad now!” Those mighty throbs rolled and reverberated from the hills, filling the night air with waves of thunder, none the less awe-inspiring now that their true import was realised. The entire population was aroused, and each building seemed to cast forth an armed host, while, as through some magic touch, a circle of fires sprung up on all sides, beginning to illumine both valley and barrier. Bruno stood like one appalled, really fascinated by this transformation scene for which he had been so poorly prepared; but Ixtli better comprehended their situation, and gripping an arm he muttered, hastily: “Come, brother; stop more, make too late. Must hide, now. Dat stop go back way came. Come!” Bruno roused himself with an effort, then yielded to the Aztec's guidance, crouching low as the brief bit of clear moonlight had to be traversed.
