Looking back across the chasm, we saw the Incas tumbling by twos and threes over the boulder on the other side. As they saw the yawning abyss that separated them from their prey they stopped short and gazed across in profound astonishment.

Others came to join them, until there were several hundred of the black, ugly forms huddled together on the opposite rim of the chasm, a hundred feet away.

I ran over the group with a keen eye, seeking the figure of the Inca king, and soon my search was successful. He stood a step in front of the others, a little to the right. I pointed him out to Harry and Desiree.

"It's up to him to walk right out again," said Harry.

Desiree shivered, and proceeded to send her last invitation to the devil.

Turning suddenly, she grasped Harry's spear and tore it from his hand.

Before we realized her purpose, she stepped forward until her foot rested on the very edge of the chasm, and had hurled the spear across straight at the Inca king.

It missed him, but struck another Inca standing near full in the breast. Quick as lightning the king turned, grasped the shaft of the spear, and pulled it forth, and with his white teeth gleaming in a snarl of furious hate, sent it whistling through the air straight at Desiree.

Harry and I sprang forward with a shout of warning; Desiree stood motionless as a statue. We grasped her frantically and pulled her back, but too late.

She came, but only to fall lifeless into our arms with the spear buried deep in her white throat.

We laid her on the ground and knelt beside her for a moment, then Harry arose to his feet with a face white as death; and I uttered a silent and vengeful prayer as I saw him level a spear at the Inca king across the chasm. But it went wide of its mark, striking the ground at his feet.

"There was another!" cried Harry, and soon he had found it where it lay on the ground and sent it, too, hurtling across.

This time he missed by inches. The spear flew just past the shoulder of the king and caught one who stood behind him full in the face. The stricken savage threw his arms spasmodically above his head, reeling forward against the king.

There was a startled movement along the black line; hands were outstretched in a vain effort at rescue; a savage cry burst from Harry's lips, and the next instant the king had toppled over the edge of the chasm and fallen into the bottomless pit below.

Harry turned, quivering from head to foot.

"Little enough," he said between his teeth, and again he knelt beside the body of Desiree and took her in his arms.

But her fate spoke eloquently of our own danger, and I roused him to action. Together we picked up the form of our dead comrade and carried it to the rear. I hesitated to pull forth the barbed head of the spear, and instead broke off the shaft, leaving the point buried in the soft throat, from which a crimson line extended over the white shoulder.

A short distance ahead we came to a projecting boulder, and behind that we gently laid her on the hard rock. Neither of us had spoken a word.

Harry's lips were locked tightly together; a lump rose in my throat, choking all utterance and filling my eyes with tears.

Harry knelt beside the white form and, gathering it gently in his arms, held it against his breast. I stood at his side, gazing down at him in mute sympathy and sorrow.

For a long minute there was silence--a most intense silence throughout the cavern, during which the painful throbbing of my heart was plainly audible; then Harry murmured, in a voice of the utmost tenderness: "Desiree!" And again, "Desiree! Desiree!" until I half expected the very strength and sweetness of his emotion to bring our comrade back to life.

Suddenly, with a quick, impulsive movement, he raised his head to glance at me.

"She loved you," he said; and though there was neither jealousy nor anger in his voice, somehow I could not meet his gaze.

"She loved you," he repeated in a tone half of wonder. "And you--you--"

I answered his eyes.

"She was yours," I said, with a touch of bitterness that persuaded him of the truth. "All her beauty, all her loveliness, all her charm, to be buried--Ah! G.o.d help us--"

My voice broke, and I knelt on the ground beside Harry and pressed my lips to the white forehead and golden hair of what had been Le Mire.

Thus we remained for a long time.

It was hard to believe that death had in reality taken possession of the still form stretched as in repose before us. Her body, still warm, seemed quivering with the instinct of life; but the eyes were not the eyes of Desiree. I closed them, and arranged the tangled ma.s.s of hair as well as possible over her shoulders. As I did so the air, set in motion by my hand, caused some of the golden strands to tremble gently across her lips; and Harry bent forward with a painful eagerness, thinking that she had breathed.

"Dearest," he murmured, "dearest, speak to me!"

His hand sought her swelling bosom gropingly; and his eyes, as they looked pleadingly even into mine, shot into my heart and unnerved me.

I rose to my feet, scarcely able to stand, and moved away.

But the fate that had finally intervened for us--too late, alas! for one--did not leave us long with our dead. Even now I do not know what happened; at the time I knew even less. Harry told me afterward that the first shock came at the instant he had taken Desiree in his arms and pressed his lips to hers.

I had crossed to the other side of the pa.s.sage and was gazing back toward the chasm at the Incas on the other side, when again I felt the ground, absolutely without warning, tremble violently under my feet.

At the same moment there was a low, curious rumble as of the thundering of distant cannon.

I sprang toward Harry with a cry of alarm, and had crossed about to the middle of the pa.s.sage, when a deafening roar smote my ear, and the entire wall of the cavern appeared to be failing in upon us. At the same time the ground seemed to sink directly away beneath my feet with an easy, rocking motion as of a wave of the ocean. Then I felt myself plunging downward with a velocity that stunned my senses and took away my breath; and then all was confusion and chaos--and oblivion.

When I awoke I was lying flat on my back, and Harry was kneeling at my side. I opened my eyes, and felt that it would be impossible to make a greater exertion.

"Paul!" cried Harry. "Speak to me! Not you, too--I shall go mad!"

He told me afterward that I had lain unconscious for many hours, but that appeared to be all that he knew. How far we had fallen, or how he had found me, or how he himself had escaped being crushed to pieces by the falling rock, he was unable to say; and I concluded that he, too, had been rendered unconscious by the fall, and for some time dazed and bewildered by the shock.

Well! We were alive--that was all.

For we were weak and faint from hunger and fatigue, and one ma.s.s of bruises and blisters from head to foot. And we had had no water for something like twenty-four hours. Heaven only knows where we found the energy to rise and go in search of it; it is incredible that any creatures in such a pitiable and miserable condition as we were could have been propelled by hope, unless it is indeed immortal.

Half walking, half crawling, we went forward.

The place where we had found ourselves was a jumbled ma.s.s of boulders and broken rock, but we soon discovered a pa.s.sage, level and straight as any tunnel built by man.

Down this we made our way. Every few feet we stopped to rest. Neither of us spoke a word. I really had no sense of any purpose in our progress; I crept on exactly as some animals, wounded to death, move on and on until there is no longer strength for another step, when they lie down for the final breath.

We saw no water nor promise of any; nothing save the long stretch of dim vista ahead and the grim, black walls on either side. That, I think, for hours; it seemed to me then for years.

I dragged one leg after the other with infinite effort and pain; Harry was ahead, and sometimes, glancing back over his shoulder to find me at some distance behind, he would turn over and lie on his back till I approached. Then again to his knees and again forward. Neither of us spoke.

Suddenly, at a great distance down the pa.s.sage, much further than I had been able to see before, I saw what appeared to be a white wall extending directly across our path.

I called to Harry and pointed it out to him. He nodded vaguely, as though in wonder that I should have troubled him about so slight an object of interest, and crawled on.

But the white wall became whiter still, and soon I saw that it was not a wall. A wild hope surged through me; I felt the blood mount dizzily to my head, and I stilled the clamor that beat at my temples by an extreme effort of the will. "It can't be," I said to myself aloud, over and over; "it can't be, it can't be."

Harry turned, and his face was as white as when he had knelt by the body of Desiree, and his eye was wild.

"You fool," he roared, "it is!"

We went faster then. Another hundred yards, and the thing was certain; there it was before us. We scrambled to our feet and tried to run; I reeled and fell, then picked myself up again and followed Harry, who had not even halted as I had fallen. The mouth of the pa.s.sage was now but a few feet away; I reached Harry's side, blinking and stunned with amazement and the incredible wonder of it.
