Determined to discover what was taking place, Huetzin, by patient and persistent effort, finally forced his way to the very front rank of the spectators, and in another moment was as anxious to make good his retreat from this position as he had been to gain it. For fully a minute he was so tightly wedged in by the eager throng about him that to move was impossible, and he gazed with a horrible fascination at the awful scene disclosed through the open doorway by the flickering light of its lurid altar flames. It was a scene of human sacrifice, though not one of such every-day occurrence that the spectators were wholly hardened to it. It was a sacrifice of children; and, as one pitiful little victim after another was roughly seized by the blood-stained priests and laid beneath the merciless knife, a suppressed shudder passed through the gaping throng. Still no manifestation of disapproval was made, and every eye eagerly followed the motions of an aged priest, whose scanty white locks were blood-reddened like his body, and to whom each little heart was handed still palpitating, as it was torn from a child's breast. He was an augur, and was watched with a breathless interest as he sought for omens from the dread thing held in his hand. As each was tossed aside, evidently unpropitious, a murmur of disappointment arose from the spectators, and more than once Huetzin heard the remark: "The hour is not yet come."

Finally, sick with horror, and raging with a furious anger, the young Toltec could bear it no longer. With a stifled cry he burst through the encircling throng of human wolves, and in spite of angry words and even blows, forced his way into the open space beyond them. When once more free he fled, he knew not whither, filled with a tumult of thought the central idea of which was vengeance. At length he reached his own camp, heart-sick, and exhausted by the strength of his emotions. Here he received the reports of his scouting parties, and learned several things, which, added to his own information, kept him in a state of wakeful anxiety until morning.

At the earliest possible hour he sought an audience with the Spanish leader, to whom he imparted his fears that some deep-laid plot for the destruction of the invaders at this point was in preparation. He told Cortes of the Aztec army discovered by his scouts hidden in a valley but a short distance from the city; of the exodus of those too old or feeble to fight; of the piles of stones secretly accumulated on the house-tops adjoining certain streets; of the pits dug in those same streets and artfully concealed, after being lined with sharp-pointed stakes; of the various chance expressions that he had overheard; and of the awful, but unusual, sacrifice of children of which he had been an unwilling eye-witness. At the same time he expressed it as his belief that the hour had not yet come for springing the trap thus set. It was evident that the portents were not yet favorable, and everything seemed to be awaiting further orders, probably from Montezuma himself. From the nature of the preparations it seemed likely that nothing would be undertaken until the Spaniards were ready to leave the city and continue their march.

Marina, who interpreted this communication, added some suspicions of a similar character, that she had gleaned from certain unguarded utterances of the wife of a Cholulan cacique, with whom she had formed an acquaintance.

Although the conqueror was not one to be easily alarmed, yet he was prudent and ever on the watch for treachery among those surrounding him. So important did he deem the information just given him, that he at once doubled his precautions against a surprise. After thanking the young leader of Tlascalans for his vigilance, he requested him to return to his own camp, continue his work of acquiring a knowledge of what was taking place in and about the city, and to hold his warriors in readiness for instant action.

When Huetzin had departed, Cortes turned his attention to his immediate surroundings. He ordered that no Spaniard should pass beyond the walls of the temple enclosure in which they were quartered. Nor should one lay aside his arms, on any pretext, for a moment. The horses of the cavaliers were kept saddled and bridled, ready for instant service, and the artillery was posted beside the three gateways in the temple walls, in a position to sweep the streets leading to them.

While these preparations were being made, Marina's new acquaintance, the garrulous wife of the cacique, came to pay her a visit. In a short time the Indian girl, pretending to be anxious to escape from the Spaniards, had drawn from her a full account of the conspiracy, which, she said, originated with Montezuma. The Christians, on attempting to leave the city, were to be led into the streets prepared with pitfalls, into which it was expected the cavalry would be precipitated. In the resulting confusion they were to be attacked from the housetops and by the Aztec army that was in waiting, when their easy destruction was deemed a certainty. Even a division of the anticipated captives had already been made, and, while a certain number were to be retained for sacrifice on Cholulan altars, the remainder were to be led in triumph to Tenochtitlan, in the leathern collars, affixed to the ends of stout poles, that were even then prepared for them.

Having agreed to a plan for taking flight to the house of this talkative acquaintance that night, Marina dismissed the woman and hastened to lay the plot before Cortes. The latter, summoning his captains, disclosed it to them and asked their advice as to what course should be pursued. Some of them, in despair at the imminence of the threatened peril, advised an instant return to Tlascala, if not to the coast. Sandoval, Alvarado, and others of stouter hearts, declaring that such a retreat would certainly insure their destruction, advised that in boldly facing the danger, and continuing their onward march at all hazards, lay their only safety. Cortes agreed with this, and added that at no time since they entered the land of Anahuac had the thought of retreat been further from his mind than now.

He then sent for some of the Cholulan caciques and announced his intention of leaving their city early on the following morning. He desired that they should furnish him with a thousand porters for the transport of his artillery and baggage, and should themselves act as his guides to the limits of their domain. These requests they willingly promised to grant, and were dismissed.

That night there was little sleep in the Spanish army, and all held themselves in readiness for an attack. The period of darkness was, however, passed in peace, and through the night no sound broke the stillness of the city, save the hoarse voices of the priests proclaiming the hour from the summit of its lofty teocallis.
