Springing to the nearest couch, where reposed Jack and his father, beginning to stir and blink at his shout, Frank shook them too. All the time he continued shouting: “Everybody up. Everybody up.”

All were awake by now, sitting up in bed or springing to the floor. And the sounds that had caused Frank to awaken could be heard plainly.

Above the revelry in the square below, which had continued unabated hour after hour, could be heard a different hubbub, men shouting, and the sound of firearms being discharged. Ferdinand sprang to a loophole and stared out on a tossing, surging mass of humanity, lighted fitfully by the glare of the bonfires and the tossing flame of torches. All around the edges of the square, men, women and children were fleeing as if in panic. Before the great stairs of the Temple, where glowed the hugest bonfire of all, could be seen a force of men in gleaming armor—something which caused Ferdinand to rub his eyes and wonder if he were dreaming. They were close knit and firing to the rear as they advanced steadily.

“Look, look,” cried Ferdinand.

All sprang to the loopholes.

The armor-clad force set foot on the stairway and started upward, those in the rear continuing their rear-guard fight.

“What is it? Who’s fighting?”

They craned to see the opposing force. Ah, there it was. A rabble of men from the direction of the fortress, some with firearms which they were discharging at the group mounting the Temple stairs, others armed only with spears. Some wore helmet or breastplate, but none were fully clothed in armor. They were shouting with rage, and it seemed to the onlookers there were cries of “Huaca, Huaca.”

What could it mean? They stared, fascinated, absorbed, beginning to grow alarmed. The force on the Temple stairs held together firmly. Several dropped as if wounded, but were lifted by comrades and supported into the Temple. The force reached the top of the stairway. Then, from the great pillars of the portico, gloomy and unlighted, above the glare of the bonfire, stepped numbers of men, similarly clad in armor, who took up position in serried rank along the top of the steps, and, at the command of a plumed leader in the middle, delivered with uplifted sword, started down the steps.

Suddenly a new clash of steel, seemingly at the base of the fortress rock, immediately below the windows of the prisoners, broke out. It was succeeded by loud shouts. They craned, but could not see.
