He was tempted to go up to the entrance of the stairway and see what was going forward in the camp, but he resisted the impulse.  For the sake of caution he triumphed over curiosity, and remained a long time on the steps, beside the niche in which his lamp sat.  Then he began to calculate how much longer the oil would last, and he placed the time at about thirty hours.  Surely some decisive event would happen in his favor before the last drop was burned.

After an interminable time the air on the stairway seemed to him to be growing colder, and he inferred that night had come.  Taking the lantern he climbed the steps and peered out at the ancient doorway.  He saw lights below, and he could discern dimly the shapes of tents.  Disappointed, he returned to his place on the steps, and, after another long wait, fell asleep again.  When he awoke he calculated by the amount of oil left in the lamp that at least twelve hours had passed since his previous awakening.

Once more he made a great effort of the will in order to achieve a conquest over curiosity and impatience.  He would not return to the entrance until the oil had only an hour more to burn.  Necessity had proved so stern a master that he was able to keep his resolution.  Many long, long hours passed and sometimes he dozed or slept, but he did not go to the entrance.  The oil at last marked the final hour, and, taking up the lamp, he went back to the entrance.

Ned looked out and then gave a cry of joy.  It was broad daylight, but the army was gone, soldiers, horses, tents, everything.  The Calle de los Muertos was once more what its name meant.  Silence and desolation had regained the ruined city.  He blew out the lantern and set it down at the opening.  It had served him well.  Then he went out and climbed again to the summit of the pyramid, from which he examined the valley long and well.

He saw no signs of human life anywhere.  Traces of the camp remained in abundance, but the army itself had vanished.  There were no lurking camp followers to make him trouble.  He descended to the ground, and stood a while, drawing in deep draughts of the fresh daylight air.  It had not been oppressive in the pyramid, but there is nothing like the open sky above.  He went down to the Teotihuacan, and, choosing a safe place, bathed in its waters.  Then he resumed the flight across the hills which had been delayed so long.  He knew by the sun that it was morning not far advanced, and he wished to travel many miles before night.  He saw abundant evidences on the great highway that the army was marching toward Vera Cruz, and as before he traveled on a line parallel with it, but at least a mile away.  He passed two sheep herders, but he displayed the machete, and whistling carelessly went on.  They did not follow, and he was sure that they took him for a bandit whom it would be wise to let alone.

Ned wandered on for two or three days.  In one of his turnings among the mountains he lost the Vera Cruz highway, and came out again upon a wide, sandy plain, dotted with scattered cactus.  As he was crossing it a Norther came up, and blew with great fierceness.  Sand was driven into his face with such force that it stung like shot.  The cold became intense, and if it had not been for the serape he might have perished.
