With what sensations of awe must she first have watched the sun moving slowly across the heavens to disappear at last beneath the western horizon, leaving in his wake that which the Mahar had never before witnessed--the darkness of night? For upon Pellucidar there is no night. The stationary sun hangs forever in the center of the Pellucidarian sky--directly overhead.
Then, too, she must have been impressed by the wondrous mechanism of the prospector which had bored its way from world to world and back again. And that it had been driven by a rational being must also have occurred to her.
Too, she bad seen me conversing with other men upon the earth's surface. She had seen the arrival of the caravan of books and arms, and ammunition, and the balance of the heterogeneous collection which I had crammed into the cabin of the iron mole for transportation to Pellucidar.
She had seen all these evidences of a civilization and brain-power transcending in scientific achievement anything that her race had produced; nor once had she seen a creature of her own kind.
There could have been but a single deduction in the mind of the Mahar--there were other worlds than Pellucidar, and the gilak was a rational being.
Now the creature at my side was creeping slowly toward the near-by sea. At my hip hung a long-barreled six-shooter--somehow I had been unable to find the same sensation of security in the newfangled automatics that had been perfected since my first departure from the outer world--and in my hand was a heavy express rifle.
I could have shot the Mahar with ease, for I knew intuitively that she was escaping--but I did not.
I felt that if she could return to her own kind with the story of her adventures, the position of the human race within Pellucidar would be advanced immensely at a single stride, for at once man would take his proper place in the considerations of the reptilia.
At the edge of the sea the creature paused and looked back at me. Then she slid sinuously into the surf.
For several minutes I saw no more of her as she luxuriated in the cool depths.
Then a hundred yards from shore she rose and there for another short while she floated upon the surface.
Finally she spread her giant wings, flapped them vigorously a score of times and rose above the blue sea. A single time she circled far aloft--and then straight as an arrow she sped away.
I watched her until the distant haze enveloped her and she had disappeared. I was alone.
My first concern was to discover where within Pellucidar
I might be--and in what direction lay the land of the Sarians where Ghak the Hairy One ruled.
But how was I to guess in which direction lay Sari?
And if I set out to search--what then?
Could I find my way back to the prospector with its priceless freight of books, firearms, ammunition, scientific instruments, and still more books--its great library of reference works upon every conceivable branch of applied sciences?
And if I could not, of what value was all this vast storehouse of potential civilization and progress to be to the world of my adoption?
Upon the other hand, if I remained here alone with it, what could I accomplish single-handed?
Nothing.
But where there was no east, no west, no north, no south, no stars, no moon, and only a stationary midday sun, how was I to find my way back to this spot should ever I get out of sight of it?
I didn't know.
For a long time I stood buried in deep thought, when it occurred to me to try out one of the compasses I had brought and ascertain if it remained steadily fixed upon an unvarying pole. I reentered the prospector and fetched a compass without.
Moving a considerable distance from the prospector that the needle might not be influenced by its great bulk of iron and steel I turned the delicate instrument about in every direction.
Always and steadily the needle remained rigidly fixed upon a point straight out to sea, apparently pointing toward a large island some ten or twenty miles distant.
This then should be north.
I drew my note-book from my pocket and made a careful topographical sketch of the locality within the range of my vision. Due north lay the island, far out upon the shimmering sea.
The spot I had chosen for my observations was the top of a large, flat boulder which rose six or eight feet above the turf. This spot I called Greenwich. The boulder was the "Royal Observatory."
I had made a start! I cannot tell you what a sense of relief was imparted to me by the simple fact that there was at least one spot within Pellucidar with a familiar name and a place upon a map.
It was with almost childish joy that I made a little circle in my note-book and traced the word Greenwich beside it.
Now I felt I might start out upon my search with some assurance of finding my way back again to the prospector.
I decided that at first I would travel directly south in the hope that I might in that direction find some familiar landmark. It was as good a direction as any.
This much at least might be said of it.
Among the many other things I had brought from the outer world were a number of pedometers. I slipped three of these into my pockets with the idea that I might arrive at a more or less accurate mean from the registrations of them all.
On my map I would register so many paces south, so many east, so many west, and so on. When I was ready to return I would then do so by any route that I might choose.
I also strapped a considerable quantity of ammunition across my shoulders, pocketed some matches, and hooked an aluminum fry-pan and a small stew-kettle of the same metal to my belt.
I was ready--ready to go forth and explore a world!
Ready to search a land area of 124,110,000 square miles for my friends, my incomparable mate, and good old Perry!
And so, after locking the door in the outer shell of the prospector, I set out upon my quest. Due south I traveled, across lovely valleys thick-dotted with grazing herds.
Through dense primeval forests I forced my way and up the slopes of mighty mountains searching for a pass to their farther sides.
