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 simple 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 be-fore 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 ammunition--
