"Safe with Valverde! Come!" Pedro dragged him out of ear-shot of the Inca, warning him to hold his tongue. A second arrow sped its flaming course, then a third; and at once, from a hundred points around the doomed capital, mounted thin pencillings of fire answering those from the fortress and falling like a shower of meteors. Arrow after arrow flashed out from the parapet into the surrounding gloom, and Cristoval gazed spellbound. Below, where the first had descended, was a tiny, wavering flame. While he watched, speechless, breathless, it grew with every second, its base spreading rapidly with ragged outline over the tinder-like thatch of one of the nearer buildings. Beyond, another feeble blaze was springing, and not far from this, a third. The first was now leaping, sending up a tenuous column of smoke which grew ruddy momentarily, and was seized by the wind and swept away toward the eastern hills. The flame waxed with incredible swiftness, lost its brilliance, turned deep and angry, with a lurid veil around it, through which darted red tongues, whipping plumes, and forked lashes. In a moment the smoke was rolling upward in volumes, showing whirling gaps with depths of murky incandescence, masses of black rising heavily after eddying sprays of sparks and burning fragments of straw. Where the first arrow had fallen was a volcano of fire with smaller craters bursting out on every hand. In the distant suburbs were splashes of flame and towers of smoke in a huge, infernal circle, and the watch-fires on the hills were gradually blotted out by a broken, rufous curtain. Now the roofs of palaces stood out in pallid relief against the inky blackness of the streets, and the golden thatch of the Temple of the Sun was gleaming fitfully in the wavering illumination. From the square, at the first outbreak of the fire, had risen shouts of alarm, the startled clamor of trumpets, then the dismal howling of Cañares. But shortly these had ceased, the beleaguered stricken into dumbness by the terrific vengeance with which they were menaced. The city had grown strangely still, as if waiting, aghast, for its fate. Cristoval gazed in stupefaction, held in a paralysis by thought of the danger to the loved one within the swiftly growing chain of conflagration. It seemed an age before his tense muscles obeyed his will. A suppressed exclamation from Pedro at last dissolved the spell, and with a groan he dashed toward his quarters. Mocho was approaching, and the cavalier ran against him. "Whither, friend?" demanded the general, detaining him forcibly. Cristoval made a wild gesture toward the fire. "To arm—into the city—the Ñusta Rava!" He broke away. Mocho looked after him, dumbfounded, then hastened to his command and called an officer. "Take fifty, Rimachi," he said, hurriedly, "and follow the Viracocha Cristoval. Obey his orders as mine. He goeth into Cuzco in aid of the Ñusta Rava. Go first to his quarters in the Paucar Marca. Speed!"
