With one exception--hunger. But there would be plenty of time to think of that; for the present we had our fish, which was sufficient for the three of us for a month, if we could keep it fresh that long. And the water was at our very feet.

The bodies wedged in the mouth of the crevice began to disappear, allowing the light from the urns to filter through; they were removing their dead. I could see the black forms swaying and pulling not five feet away. But I stood motionless, saving my spear and my strength for any who might try to force an entrance.

Soon the crevice was clear, and from where I stood I commanded a view of something like three-quarters of the ledge. It was one ma.s.s of black forms, packed tightly together, gazing at our retreat.

They looked particularly silly and helpless to me then, rendered powerless as they were by a little bit of rock. Brute force was all they had; and nature, being the biggest brute of all, laughed at them.

But I soon found that they were not devoid of resource. For perhaps fifteen minutes the scene remained unchanged; not one ventured to approach the crevice. Then there was a sudden movement and shifting in the ma.s.s; it split suddenly in the middle; they pressed off to either side, leaving an open lane between them leading directly toward me.

Down this lane suddenly dashed a dozen or more of the savages, with spears aloft in their brawny arms. I was taken by surprise and barely had time to cut and run for the ledge within.

As it was I did not entirely escape; the spears came whistling through the crevice, and one of them lodged in my leg just below the thigh.

I jerked it out with an oath and turned to meet the attack. I was now clear of the crevice, standing on the ledge inside, near Harry and Desiree. I called to them to go to one side, out of the range of the spears that might come through. Harry took Desiree in his arms and carried her to safety.

As I expected, the Incas came rushing through the crevice--that narrow lane where a man could barely push through without squeezing. The first got my spear full in the face--a blow rather than a thrust, for I had once or twice had difficulty in retrieving it when I had buried it deep.

As he fell I struck at the one behind. He grasped the spear with his hand, but I jerked it free and brought it down on his head, crushing him to the ground. It was mere butchery; they hadn't a chance in the world to get at me. Another fell, and the rest retreated. The crevice was again clear, save for the bodies of the three who had fallen.

I turned to where Harry and Desiree were seated on the further edge of the ledge. Her body rested against his; her head lay on his shoulder.

As I looked at them, smiling, her eyes suddenly opened wide and she sprang to her feet and started toward me.

"Paul! You are hurt! Harry, a bandage--quick; your shirt--anything!"

I looked down at the gash on my leg, which was bleeding somewhat freely.

"It's nothing," I declared; "a mere tear in the skin. But your ankle!

I thought it was sprained?"

She had reached my side and bent over to examine my wound; but I raised her in my arms and held her before me.

"That," I said, "is nothing. Believe me, it isn't even painful. I shall bandage it myself; Harry will take my place here. But your foot?"

"That, too, is nothing," she answered with a half-smile. "I merely twisted it; it is nearly well already. See!"

She placed her weight on the injured foot, but could not suppress a faint grimace of pain.

Calling to Harry to watch the crevice, I took Desiree in my arms and carried her back to her seat.

"Now sit still," I commanded. "Soon we'll have dinner; in the mean time allow me to say that you are the bravest woman in the world, and the best sport. And some day we'll drink to that--from a bottle."

But facts have no respect for sentiment and fine speeches. The last words were taken from my very mouth by a ringing cry from Harry:

"Paul! By gad, they're coming at us from the water!"

Chapter XVI.

THE ESCAPE.

The ledge on which we rested was about forty feet square. Back of us was a confused ma.s.s of boulders and chasms, across which I had come when I first encircled the cavern and found Harry.

In front was the crevice, guarded by the two ma.s.sive boulders. On the right the ledge met the solid wall of the cavern, and on the left was the lake itself, whose waters rippled gently at our very feet.

At sound of Harry's warning cry I ran to the water's edge and peered round the side of the boulder. He was right; but what I saw was not very alarming.

Two rafts had been launched from the enemy's camp. Each raft held three Incas--more would have sunk them. Two were paddling, while the third balanced himself in the center, brandishing a spear aloft.

Turning to Desiree, I called to her to move behind a projecting bit of rock. Then, leaving Harry to guard the crevice in case of a double attack, I took three of our four spears--one of which had made the wound in my leg--and stood at the water's edge awaiting the approach of the rafts.

They came slowly, and their appearance was certainly anything but terrifying.

"Not much of a navy," I called to Harry; and he answered, with a laugh: "Lucky for us! Look at our coast defense!"

One of the rafts was considerably ahead of the other, and in another minute it had approached within fifty feet of the ledge. The Inca in the center stood with legs spread apart and his spear poised above his head; I made no movement, thinking that on such precarious footing he would have difficulty to hurl the thing at all. Wherein I underrated his skill, and it nearly cost me dear.

Suddenly, with hardly a movement of his body, his arm snapped forward.

I ducked to one side instinctively and heard the spear whistle past my ear with the speed of a bullet, so close that the b.u.t.t of the shaft struck the side of my head a glancing blow and toppled me over.

I sprang quickly to my feet, and barely in time, for I saw the Inca stoop over, pick up another spear from the raft, and draw it back above his head. At the same moment the second raft drew up alongside, and as I fell to the ground flat on my face I heard the two spears whistle shrewdly over me.

At that game they were my masters; it would have been folly to have tried conclusions with them with their own weapons. As the spears clattered on the ground thirty feet away I sprang to my feet and ran to the farther side of the ledge, where I had before noticed some loose stones in a corner.

With two or three of these in my hands I ran back to the water's edge, meeting two more of the spears that came twisting at me through the air, one of which tore the skin from my left shoulder.

A quick glance at the crevice as I pa.s.sed showed me Harry fighting at its entrance; they were at us there, too. I heard Desiree shout something at me, but didn't catch the words.

My first stone found its goal. The two rafts, side by side not forty feet away, were a fair mark. The stone was nearly the size of a man's head and very heavy; I had all I could do to get the distance.

It struck the raft on the right fairly; the thing turned turtle in a flash, precipitating its occupants onto the other raft. The added weight carried that, too, under the surface, and the six Incas were floundering about in the water.

I expected to see them turn and swim for the landing opposite; but, instead, they headed directly toward me!

The light from the urns was but faint, and it was not easy to distinguish their black heads against the black water; still, I could see their approach. Two of them held spears in their hands; I saw the copper heads flash on high.

I stood at the edge of the lake, wondering at their folly as I waited; they were now scarcely ten feet away. Another few strokes and the foremost stretched out his hand to grasp the slippery ledge; my spear came down crushingly on his head and he fell back into the water.

By that time another had crawled half onto the ledge, and another; a blow and a quick thrust, and they, too, slipped back beneath the surface, pawing in agony, not to rise again.

Just in time I saw that one of the remaining three had lifted himself in the water not five feet away, with his spear aimed at my breast.

But the poor devil had no purchase for his feet and the thing went wide.

The next instant he had received a ten-pound stone full in the face and went down with a gurgle. At that the remaining two, seeming to acquire a glimmering of intelligence, turned and swam hastily away. I let them go.

Turning to Harry, I saw that the crevice also was clear. He had left his post and started toward me, but I waved him back.

"All right here, Hal: have they given it up?"
