“But there is that ‘if,’” said Ja. “We have eaten and slept many times since they threw us into this dark hole, yet we are no nearer escape now than we were at the moment that they put us here; nor do we even know what fate lies in store for us.”
“These other prisoners tell us,” resumed David, “that the fact that we were not immediately killed, which is the customary fate of prisoners of war among the Korsars, indicates that they are saving us for some purpose; but what that purpose is I cannot conceive.”
“I can,” said Tanar. “In fact I am quite sure that I know.”
“And what is it?” demanded Ja.
“They wish us to teach them how to make firearms and powder such as ours,” replied the Sarian. “But where do you suppose they ever got firearms and powder in the first place?”
“Or the great ships they sail,” added Ja; “ships that are even larger than those which we build? These things were unknown in Pellucidar before David and Perry came to us, yet the Korsars appear to have known of them and used them always.”
“I have an idea,” said David; “yet it is such a mad idea that I have almost hesitated to entertain it, much less to express it.”
“What is it?” asked Tanar.
“It was suggested to me in my conversations with the Korsars themselves,” replied the Emperor. “Without exception they have all assured me that their ancestors came from another world—a world above which the sun did not stand perpetually at zenith, but crossed the heavens regularly, leaving the world in darkness half the time. They say that a part of this world is very cold and that their ancestors, who were seafaring men, became caught with their ships in the frozen waters; that their compasses turned in all directions and became useless to them and that when finally they broke through the ice and sailed away in the direction that they thought was south, they came into Pellucidar, which they found inhabited only by naked savages and wild beasts. And here they set up their city and built new ships, their numbers being augmented from time to time by other seafaring men from this world from which they say they originally came.
“They intermarried with the natives, which in this part of Pellucidar seemed to have been of a very low order.” David paused.
