That appeared to have been a final effort, for there the battle ended. The oarsman made quickly for the shore, paddling with remarkable dexterity and swiftness, while the other stood braced, holding firmly to the spear-thongs. Another minute and they had leaped upon the ledge, drawing the raft after them, and, by tugging together on the lines, had landed their victim of the deep.

It appeared to be a large black fish of a shape I had never before seen. But it claimed little of my attention; my eye was on the two spears which had been drawn from the still quivering body and which now lay on the ground well away from the water's edge, while the two Incas were dragging their catch toward the mouth of the passage leading from the cavern.

I wanted those spears. I did not stop to ask myself what I intended to do with them; if I had I would probably have been hard put to it for an answer. But I wanted them, and I sat in my dark corner gazing at them with greedy eyes.

The Incas had disappeared in the passage.

Finally I rose and began to search for an exit from the recess in which I had hidden myself. At first there appeared to be none, but at length I found a small crevice between two boulders in the rear. Into this I squeezed my body with some difficulty.

The rock pressed tightly against me on both sides, and the sharp corners bruised my body, but I wormed my way through for a distance of fifteen or twenty feet. Then the crevice opened abruptly, and I found myself on a broad ledge ending apparently in space. I advanced cautiously to its edge, but intervening boulders shut off the light, and I could see no ground below.

Throwing prudence to the winds, I let myself over the outermost corner, hung for a moment by my hands, and dropped. My feet touched ground almost instantly—the supposedly perilous fall amounted to something like twelve inches.

I turned round, feeling a little foolish, and saw that from where I stood the ledge and part of the lake were in full view. I could see the spears still lying where they had been thrown down.

But as I looked the two Incas emerged from the passage. They picked up the spears, walked to the raft, and again launched it and paddled toward the center of the lake.

I thought, "Here is my chance; I must make that ledge before they return," and I started forward so precipitately that I ran head on into a massive boulder and got badly stunned for my pains. Half dazed, I went on, groping my way through the semidarkness.
