I pointed to the exit in the middle. "That! We should have taken it in the first place. On the raft we probably descended altogether something like five hundred feet from the level where we started--possibly twice that distance. And this pa.s.sage which slopes upward will probably take us back."

"At least, it's as good as the other," Harry agreed; and we entered it.

We had not proceeded far before we found ourselves in difficulties.

The gentle slope became a steep incline. Great rocks loomed up in our path.

In spots the pa.s.sage was so narrow that two men could hardly have walked abreast through it, and its walls were rough and irregular, with sharp points projecting unexpectedly into our very faces.

Still we went forward and upward, scrambling over, under, round, between. At one point, when Harry was a few yards in front of me, he suddenly disappeared from sight as though swallowed by the mountain.

Rushing forward, I saw him scrambling to his feet at the bottom of a chasm some ten feet below. Luckily he had escaped serious injury, and climbed up on the other side, while I leaped across--a distance of about six feet.

"They could never have brought her through this," he declared, rubbing a bruised knee.

"Do you want to go back?" I asked.

But he said that would be useless, and I agreed with him. So we struggled onward, painfully and laboriously. The sharp corners of the rocks cut our feet and hands, and I had an ugly bruise on my left shoulder, besides many lesser ones. Harry's injured knee caused him to limp and thus further r.e.t.a.r.ded our progress.

At times the pa.s.sage broadened out until the wall on either side was barely visible, only to narrow down again till it was scarcely more than a crevice between the giant boulders. The variation of the incline was no less, being at times very nearly level, and at others mounting upward at an angle whose ascent was all but impossible.

Somehow we crawled up, like flies on a wall.

When we came to a stream of water rushing directly across our path at the foot of a towering rock Harry gave a cry of joy and ran forward. I had not known until then how badly his knee was hurt, and when I came up to where he was bathing it in the stream and saw how black and swollen it was, I insisted that he give it a rest. But he absolutely refused, and after we had quenched our thirst and gotten an easy breath or two we struggled to our feet and on.

After another hour of scrambling and failing and hanging on by our finger nails, the way began to be easier. We came to level, clear stretches with only an occasional boulder or ravine, and the rock became less cruel to our bleeding feet. The relief came almost too late, for by that time every movement was painful, and we made but slow progress.

Soon we faced another difficulty when we came to a point where a split in the pa.s.sage showed a lane on either side. One led straight ahead; the other branched off to the right. They were very similar, but somehow the one on the right looked more promising to us, and we took it.

We had followed this but a short distance when it broadened out to such an extent that the walls on either side could be seen but dimly. It still sloped upward, but at a very slight angle, and we had little difficulty in making our way. Another half-hour and it narrowed down again to a mere lane.

We were proceeding at a fairly rapid gait, keeping our eyes strained ahead, when there appeared an opening in the right wall at a distance of a hundred feet or so. Not having seen or heard anything to recommend caution, we advanced without slackening our pace until we had reached it.

I said aloud to Harry, "Probably a cross-pa.s.sage," and then jerked him back quickly against the opposite wall as I saw the real nature of the opening.

It led to a small room, with a low ceiling and rough walls, dark as the pa.s.sage in which we stood, for it contained no light.

We could see its interior dimly, but well enough to discover the form of an Inca standing just within the doorway. His back was toward us, and he appeared to be fastening something to the ceiling with strips of hide.

It was evident that we had not been seen, and I started to move on, grasping Harry's arm. It was then that I became aware of the fact that the wall leading away in front of us--that is, the one on the right--was marked as far as the eye could reach with a succession of similar openings.

They were quite close together; from where we stood I could see thirty or forty of them. I guessed that they, too, led to rooms similar to the one in front of us, probably likewise occupied; but it was necessary to go on in spite of the danger, and I pulled again at Harry's arm.

Then, seeing by his face that something had happened, I turned my eyes again on the Inca in the room. He had turned about, squarely facing us. As we stood motionless he took a hasty step forward; we had been discovered.

There was but one thing to do, and we didn't hesitate about doing it.

We leaped forward together, crossing the intervening s.p.a.ce in a single bound, and bore the Inca to the floor under us.

My fingers were round his throat, Harry sat on him. In a trice we had him securely bound and gagged, using some strips of hide which we found suspended from the ceiling.

"By gad!" exclaimed Harry in a whisper. "Look at him! He's a woman!"

It was quite evident--disgustingly so. Her eyes, dull and sunken, appeared as two large, black holes set back in her skull. Her hair, matted about her forehead and shoulders, was thick and coa.r.s.e, and blacker than night. Her body was innocent of any attempt at covering.

Altogether, not a very pleasant sight; and we bundled her into a corner and proceeded to look round the room, being careful to remain out of the range of view from the corridor as far as possible.

The room was not luxuriously furnished. There were two seats of stone, and a couch of the same material covered with thick hides. In one corner was a pile of copper vessels; in another two or three of stone, rudely carved. Some torn hides lay in a heap near the center of the room. From the ceiling were suspended other hides and some strips of dried fish.

Some of the latter we cut down with the points of our spears and retired with it to a corner.

"Ought we to ask our hostess to join us?" Harry grinned.

"This tastes good, after the other," I remarked.

Hungry as we were, we made sad havoc with the lady's pantry. Then we found some water in a basin in the corner and drank--not without misgivings. But we were too thirsty to be particular.

Then Harry became impatient to go on, and though I had no liking for the appearance of that long row of open doorways, I did not demur.

Taking up our spears, we stepped out into the corridor and turned to the right.

We found ourselves running a gantlet wherein discovery seemed certain.

The right wall was one unbroken series of open doorways, and in each of the rooms, whose interiors we could plainly see, were one or more of the Inca Women; and sometimes children rolled about on the stony floor.

In one of them a man stood; I could have sworn that he was gazing straight at us, and I gathered myself together for a spring; but he made no movement of any kind and we pa.s.sed swiftly by.

Once a little black ball of flesh--a boy it was, perhaps five or six years old--tumbled out into the corridor under our very feet. We strode over him and went swiftly on.

We had pa.s.sed about a hundred of the open doorways, and were beginning to entertain the hope that we might, after all, get through without being discovered, when Harry suddenly stopped short, pulling at my arm.

At the same instant I saw, far down the corridor, a crowd of black forms moving toward us.

Even at that distance something about their appearance and gait told us that they were not women. Their number was so great that as they advanced they filled the pa.s.sage from wall to wall.

There was but one way to escape certain discovery; and distasteful as it was, we did not hesitate to employ it. In a glance I saw that we were directly opposite an open doorway; with a whispered word to Harry I sprang across the corridor and within the room. He followed.

Inside were a woman and two children. As we entered they looked up, startled, and stood gazing at us in terror. For an instant we held back, but there was nothing else for it; and in another minute we had overpowered and bound and gagged them and carried them to a corner.

The children were ugly little devils and the woman very little above a brute; still we handled them as tenderly as possible. Then we crouched against the wall where we could not be seen from the corridor, and waited.

Soon the patter of many footsteps reached our ears. They pa.s.sed; others came, and still others. For many minutes the sound continued steadily, unbroken, while we sat huddled up against the wall, scarcely daring to breathe.

Immediately in front of me lay the forms of the woman and the children; I could see their dull eyes, unblinking, looking up at me in abject terror. Still the patter of footsteps sounded from without, with now and then an interval of quiet.

Struck by a sudden thought, I signaled to Harry; and when he had moved further back into his corner I sprang across the room in one bound to his side. A word or two of whispering, and he nodded to show that he understood. We crouched together flat against the wall.

My thought had come just in time, for scarcely another minute had pa.s.sed when there suddenly appeared in the doorway the form of an Inca.

He moved a step inside, and I saw that there was another behind him. I had not counted on two of them! In the arms of each was a great copper vessel, evidently very heavy, for their effort was apparent as they stooped to place the vessels on the ground just within the doorway.

As they straightened up and saw that the room before them was empty, their faces filled with surprise. At the same moment a movement came from the woman in the corner; the two men glanced at them with a start of wonder; and as I had foreseen, they ran across and bent over the prostrate forms.

The next instant they, too, were p.r.o.ne on the floor, with Harry and me on top of them. They did not succ.u.mb without a struggle, and the one I had chosen proved nearly too much for me.

The great muscles of his chest and legs strained under me with a power that made me doubtful for a moment of the outcome; but the Incas themselves had taught us how to conquer a man when you attack him from behind, and I grasped his throat with all the strength there was in my fingers.
