Following the river downward I soon lost sight of the tiny planet as I entered the mazes of a lofty forest. Nor did I catch another glimpse of it for some time--several marches at least. However, when the river led me to the sea, or rather just before it reached the sea, of a sudden the sky became overcast and the size and luxuriance of the vegetation diminished as by magic--as if an omnipotent hand had drawn a line upon the earth, and said:
"Upon this side shall the trees and the shrubs, the grasses and the flowers, riot in profusion of rich colors, gigantic size and bewildering abundance; and upon that side shall they be dwarfed and pale and scant."
Instantly I looked above, for clouds are so uncommon in the skies of Pellucidar--they are practically unknown except above the mightiest mountain ranges--that it had given me something of a start to discover the sun obliterated. But I was not long in coming to a realization of the cause of the shadow.
Above me hung another world. I could see its mountains and valleys, oceans, lakes, and rivers, its broad, grassy plains and dense forests. But too great was the distance and too deep the shadow of its under side for me to distinguish any movement as of animal life.
Instantly a great curiosity was awakened within me.
The questions which the sight of this planet, so tantalizingly close, raised in my mind were numerous and unanswerable.
Was it inhabited?
If so, by what manner and form of creature?
Were its people as relatively diminutive as their little world, or were they as disproportionately huge as the lesser attraction of gravity upon the surface of their globe would permit of their being?
As I watched it, I saw that it was revolving upon an axis that lay parallel to the surface of Pellucidar, so that during each revolution its entire surface was once exposed to the world below and once bathed in the heat of the great sun above. The little world had that which Pellucidar could not have--a day and night, and--greatest of boons to one outer-earthly born--time.
Here I saw a chance to give time to Pellucidar, using this mighty clock, revolving perpetually in the heavens, to record the passage of the hours for the earth below.
Here should be located an observatory, from which might be flashed by wireless to every corner of the empire the correct time once each day. That this time would be easily measured I had no doubt, since so plain were the landmarks upon the under surface of the satellite that it would be but necessary to erect a ****** instrument and mark the instant of passage of a given landmark across the instrument.
But then was not the time for dreaming; I must devote my mind to the purpose of my journey. So I hastened onward beneath the great shadow. As I advanced
I could not but note the changing nature of the vegetation and the paling of its hues.
The river led me a short distance within the shadow before it emptied into the Sojar Az. Then I continued in a southerly direction along the coast toward the village of Thuria, where I hoped to find Goork and deliver to him my credentials.
I had progressed no great distance from the mouth of the river when I discerned, lying some distance at sea, a great island. This I assumed to be the stronghold of Hooja, nor did I doubt that upon it even now was Dian.
The way was most difficult, since shortly after leaving the river I encountered lofty cliffs split by numerous long, narrow fiords, each of which necessitated a considerable detour. As the crow flies it is about twenty miles from the mouth of the river to Thuria, but before
I had covered half of it I was fagged. There was no familiar fruit or vegetable growing upon the rocky soil of the cliff-tops, and I would have fared ill for food had not a hare broken cover almost beneath my nose.
I carried bow and arrows to conserve my ammunitionsupply, but so quick was the little animal that I had no time to draw and fit a shaft. In fact my dinner was a hundred yards away and going like the proverbial bat when I dropped my six-shooter on it. It was a pretty shot and when coupled with a good dinner made me quite contented with myself.
After eating I lay down and slept. When I awoke I was scarcely so self-satisfied, for I had not more than opened my eyes before I became aware of the presence, barely a hundred yards from me, of a pack of some twenty huge wolf-dogs--the things which Perry insisted upon calling hyaenodons--and almost simultaneously I discovered that while I slept my revolvers, rifle, bow, arrows, and knife had been stolen from me.
And the wolf-dog pack was preparing to rush me.
