That evening, Jack received an invitation from Ixtlilxochitli to be present at dawn next morning on the summit of the teocalli, to take part in a religious ceremony of peculiar solemnity. The god Huitzilopochtli was to be asked if it was his will that the Indian tribes should array their ranks in battle on the side of Don Hypolito Xuarez? Through the opal was the answer to be given. If it gleamed red the god desired war, if blue there was to be peace in the land. Seeing the bloodthirsty character of the deity, and the secret understanding between his high priest and Xuarez, there was but little doubt in the mind of Jack as to what the answer would be. Still, as he was anxious to know how the prophecies were given, and not averse to seeing a unique religious ceremony, he accepted the invitation of Ixtlilxochitli with avidity. For many days, messages had been sent far and wide, calling on the Indians to repair to the sacred city, and assist at the festival. The town was filled to overflowing, and all the caravansaries in the square of the sacrifice were crowded. Owing to the depth of the valley, the ceremony could not take place precisely at dawn, as it was some time before the sun rose above the peaks of the surrounding mountains. His presence was indispensable to the ceremony, as the heart of the victim had to be held up by the officiating priest for the benediction of his rays. Jack rather shrank from witnessing this horrible rite, particularly as, unless he succeeded in effecting his escape, he would probably be forced to take part in the same function; but curiosity triumphed over repugnance, and he looked forward eagerly to beholding this extraordinary spectacle. In the grey light of dawn he was awakened by the thunder of the serpent-skin drums, which for some hours roared continuously. Springing out of bed, he hastily put on his clothes, and had just finished dressing when Cocom entered the room. The old Indian was arrayed in white cotton garments, with a chaplet of flowers on his grey locks. He had another wreath, of red blossoms, which he held out for Jack's acceptance--an offer which that young man promptly refused. Red was the emblem of a dedicated victim, and Jack, knowing this, objected to being thus distinguished. "Carrajo! No, mi amigo," he said, vigorously, "I am not going to be decked out as a victim yet." "Ixtlilxochitli will be angry, Señor." "He can be as angry as the devil, for all I care. I don't intend taking any part in this infernal idol worship. Don't they look on me as a god, Cocom?" "Yes, my lord; you are supposed to be the visible representative of Tezcatlipoca, the soul of the universe." "Bueno! Well, the soul of the universe is going to have his own way. What is the use of being Tez--what's-his-name, if you can't do as you please? Besides, I wear European clothes, and wreaths don't go with this rig-out." "As you please, Don Juan. Still, it is not wise to anger the priests."
