At the sight of Desiree Harry uttered a cry of joy, then gazed in astonishment as I appeared behind her.

“Run for your lives!” he shouted, pointing down the passage leading to the apartments beyond.  As he spoke a shower of spears descended from above, rattling on the steps and on the ground beside us.  I stooped to pick up two of them, and as Desiree and I darted forward into the passage, with Harry bringing up the rear, the Incas dashed down the stairway after us.

We found ourselves at once in the maze of lanes and passages leading to the royal apartments.  That, I thought, was as good a goal as any; and, besides, the way led to the cavern where we had once before successfully withstood our enemies.  But the way was not so easy to find.

Turn and twist about as we would, we could not shake off our pursuers.  Harry kept urging me forward, but I was using every ounce of strength that was left to me.  Desiree, too, was becoming weaker at every step, and I could hear Harry’s cry of despair as she perceptibly faltered and slackened her pace.

I soon realized that we were no longer in the passage or group of passages that led to the royal apartments and the cavern beyond.  But there was no time to seek our way; well enough if we went forward.  We found ourselves in a narrow lane, strewn with rocks, crooked and winding.

Desiree stumbled and would have fallen but for my outstretched arm.  A spear from behind whistled past my ear as we again bounded forward.  Harry was shouting to us that the Incas were upon us.

I caught Desiree’s arm and pulled her on with a last great effort.  The lane became narrower still; we brushed the wall on either side, and I pushed Desiree ahead of me and followed behind.  Suddenly she stopped short, turning to face me so suddenly that I was thrown against her, nearly knocking her down.

“Your spear!” she cried desperately.  “I can go no farther,” and she sank to the ground.

At the same moment there came a cry from Harry in the rear—­a cry that held joy and wonder—­and I turned to see him standing some distance away, gazing down the lane through which we had come.

“They’ve given up!” he called.  “They’re gone!”

And I saw that it was true.  No sound came, and no Inca was to be seen.

Then, seeing Desiree on the ground, Harry ran to us and sprang to her side.  “Desiree!” he cried, lifting her in his arms.  She opened her eyes and smiled at him, and he kissed her many times—­her hair, her lips, her eyes.  Then he placed her gently on her feet, and, supporting her with his arm, moved forward slowly.  I led the way.

The lane ahead of us was scarcely more than a crevice between the rocks; I squeezed my way through with difficulty.  Then the walls ended abruptly, just when I had begun to think we could go no farther, and we found ourselves at the entrance to a cavern so large that no wall was to be seen on any side save the one behind us.
