Occasionally, for the larger game animals and the gigantic beasts of prey, I used my express rifle, but for the most part the revolver filled all my needs.

There were times, too, when faced by a mighty cave bear, a saber-toothed tiger, or huge felis spelaea, black-maned and terrible, even my powerful rifle seemed pitifully inadequate-but fortune favored me so that I passed unscathed through adventures that even the recollection of causes the short hairs to bristle at the nape of my neck.

How long I wandered toward the south I do not know, for shortly after I left the prospector something went wrong with my watch, and I was again at the mercy of the baffling timelessness of Pellucidar, forging steadily ahead beneath the great, motionless sun which hangs eternally at noon.

I ate many times, however, so that days must have elapsed, possibly months with no familiar landscape rewarding my eager eyes.

I saw no men nor signs of men. Nor is this strange, for Pellucidar, in its land area, is immense, while the human race there is very young and consequently far from numerous.

Doubtless upon that long search mine was the first human foot to touch the soil in many places-mine the first human eye to rest upon the gorgeous wonders of the landscape.

It was a staggering thought. I could not but dwell upon it often as I made my lonely way through this virgin world. Then, quite suddenly, one day I stepped out of the peace of manless primality into the presence of man-and peace was gone.

It happened thus:

I had been following a ravine downward out of a chain of lofty hills and had paused at its mouth to view the lovely little valley that lay before me. At one side was tangled wood, while straight ahead a river wound peacefully along parallel to the cliffs in which the hills terminated at the valley's edge.

Presently, as I stood enjoying the lovely scene, as insatiate for Nature's wonders as if I had not looked upon similar landscapes countless times, a sound of shouting broke from the direction of the woods. That the harsh, discordant notes rose from the throats of men I could not doubt.
