This I saw in time, but the first thing that caught my eye was no work of nature. Fastened to the wall on the opposite side of the cavern, casting a dim, flickering light throughout its vast space, were two golden, flaming urns.

It was not fear, but a sort of nausea, that assailed me as I realized that I was still in the domain of the Incas.

The ledge on which I lay was exposed to view from nearly every point of the cavern, and the sight of those urns caused me to make a swift decision to leave it without delay. It was wet and slippery and not over three feet in width; I rose to my feet cautiously, having no appetite for another ducking.

At a distance of several feet lay another ledge, broad and level, at the farther end of which rose a massive boulder. I cleared the gap with a leap, barely made my footing, and passed behind the boulder through a crevice just wide enough to admit my body.

Then through a narrow lane onto another ledge, and from that I found my way into a dark recess which gave assurance at least of temporary safety. The sides of the cavern were a veritable maze of boulders, sloping ledges, and narrow crevices. Nature here scarcely seemed to have known what to do with herself.

I seated myself on a bit of projecting limestone, still wet and shivering. I had no boots nor trousers; my feet were bruised and swollen, and my flannel shirt and woolen underwear were but scanty protection against the chill air, damp as they were. Also, I seemed to feel a cold draft circling about me, and was convinced of the fact by the flickering flames in the golden urns.

Desolate, indeed, for I gave Harry up as lost. The thought generated no particular feeling in me; death, by force of contrast, may even appear agreeable; and I told myself that Harry had been favored of the gods.

And there I sat in the half-darkness, shrinking from a danger of whose existence I was not certain, clinging miserably to the little that was left of what the world of sunshine had known as Paul Lamar, gentleman, scientist, and connoisseur of life; sans philosophy, sans hope, and—sans-culotte.

But the senses remain; and suddenly I became aware of a movement in the water of the lake. It was as though an immense trout had leaped and split the surface. This was repeated several times, and was followed by a rhythmic sound like the regular splash of many oars. Then silence.

I peered intently forth from my corner in the recess, but could see nothing, and finally gave it up.
