I never did quite grasp him, though he endeavored to explain it to me upon numerous occasions. I suggested telepathy, but he said no, that it was not telepathy since they could only communicate when in each others' presence, nor could they talk with the Sagoths or the other inhabitants of Pellucidar by the same method they used to converse with one another.
"What they do," said Perry, "is to project their thoughts into the fourth dimension, when they become appreciable to the sixth sense of their listener. Do I make myself quite clear?""You do not, Perry," I replied. He shook his head in despair, and returned to his work. They had set us to carrying a great accumulation of Maharan literature from one apartment to another, and there arranging it upon shelves. I suggested to Perry that we were in the public library of Phutra, but later, as he commenced to discover the key to their written language, he assured me that we were handling the ancient archives of the race.
During this period my thoughts were continually upon Dian the Beautiful. I was, of course, glad that she had escaped the Mahars, and the fate that had been suggested by the Sagoth who had threatened to purchase her upon our arrival at Phutra. I often wondered if the little party of fugitives had been overtaken by the guards who had returned to search for them. Sometimes I was not so sure but that Ishould have been more contented to know that Dian was here in Phutra, than to think of her at the mercy of Hooja the Sly One. Ghak, Perry, and I often talked together of possible escape, but the Sarian was so steeped in his lifelong belief that no one could escape from the Mahars except by a miracle, that he was not much aid to us--his attitude was of one who waits for the miracle to come to him.
At my suggestion Perry and I fashioned some swords of scraps of iron which we discovered among some rubbish in the cells where we slept, for we were permitted almost unrestrained freedom of action within the limits of the building to which we had been assigned. So great were the number of slaves who waited upon the inhabitants of Phutra that none of us was apt to be overburdened with work, nor were our masters unkind to us.
We hid our new weapons beneath the skins which formed our beds, and then Perry conceived the idea of making bows and arrows--weapons apparently unknown within Pellucidar.
Next came shields; but these I found it easier to steal from the walls of the outer guardroom of the building.
We had completed these arrangements for our protection after leaving Phutra when the Sagoths who had been sent to recapture the escaped prisoners returned with four of them, of whom Hooja was one. Dian and two others had eluded them. It so happened that Hooja was confined in the same building with us. He told Ghak that he had not seen Dian or the others after releasing them within the dark grotto. What had become of them he had not the faintest conception--they might be wandering yet, lost within the labyrinthine tunnel, if not dead from starvation.
I was now still further apprehensive as to the fate of Dian, and at this time, I imagine, came the first realization that my affection for the girl might be prompted by more than friendship. During my waking hours she was constantly the subject of my thoughts, and when I slept her dear face haunted my dreams.
More than ever was I determined to escape the Mahars.
"Perry, " I confided to the old man, "if I have to search every inch of this diminutive world I am going to find Dian the Beautiful and right the wrong I unintentionally did her." That was the excuse I made for Perry's benefit.
"Diminutive world!" he scoffed. "You don't know what you are talking about, my boy," and then he showed me a map of Pellucidar which he had recently discovered among the manuscript he was arranging.
"Look," he cried, pointing to it, "this is evidently water, and all this land. Do you notice the general configuration of the two areas? Where the oceans are upon the outer crust, is land here. These relatively small areas of ocean follow the general lines of the continents of the outer world.
"We know that the crust of the globe is 500 miles in thickness;then the inside diameter of Pellucidar must be 7,000 miles, and the superficial area 165,480,000 square miles.
Three-fourths of this is land. Think of it! A land area of 124,110,000 square miles! Our own world contains but 53,000,000 square miles of land, the balance of its surface being covered by water. Just as we often compare nations by their relative land areas, so if we compare these two worlds in the same way we have the strange anomaly of a larger world within a smaller one!
"Where within vast Pellucidar would you search for your Dian? Without stars, or moon, or changing sun how could you find her even though you knew where she might be found?"The proposition was a corker. It quite took my breath away;but I found that it left me all the more determined to attempt it.
"If Ghak will accompany us we may be able to do it,"I suggested.
Perry and I sought him out and put the question straight to him.
"Ghak," I said, "we are determined to escape from this bondage. Will you accompany us?""They will set the thipdars upon us," he said, "and then we shall be killed; but--" he hesitated--"I would take the chance if I thought that I might possibly escape and return to my own people.""Could you find your way back to your own land?" asked Perry.
"And could you aid David in his search for Dian?""Yes."
"But how," persisted Perry, "could you travel to strange country without heavenly bodies or a compass to guide you?"Ghak didn't know what Perry meant by heavenly bodies or a compass, but he assured us that you might blindfold any man of Pellucidar and carry him to the farthermost corner of the world, yet he would be able to come directly to his own home again by the shortest route. He seemed surprised to think that we found anything wonderful in it.
Perry said it must be some sort of homing instinct such as is possessed by certain breeds of earthly pigeons.
