I asked them what batu meant, as I had not before heard the word. Literally translated, it is equivalent to through, finished, done-for, as applied to an individual's evolutionary progress in Caspak, and with this information was developed the interesting fact that not every individual is capable of rising through every stage to that of Galu. Some never progress beyond the Alu stage; others stop as Bo-lu, as Sto-lu, as Bandlu or as Kro-lu. The Ho-lu of the first generation may rise to become Alus; the Alus of the second generation may become Bo-lu, while it requires three generations of Bo-lu to become Band-lu, and so on until Kro-lu's parent on one side must be of the sixth generation.
It was not entirely plain to me even with this explanation, since I couldn't understand how there could be different generations of peoples who apparently had no offspring. Yet I was commencing to get a slight glimmer of the strange laws which govern propagation and evolution in this weird land.
Already I knew that the warm pools which always lie close to every tribal abiding-place were closely linked with the Caspakian scheme of evolution, and that the daily immersion of the females in the greenish slimy water was in response to some natural law, since neither pleasure nor cleanliness could be derived from what seemed almost a religious rite. Yet I was still at sea; nor, seemingly, could Ajor enlighten me, since she was compelled to use words which I could not understand and which it was impossible for her to explain the meanings of.
As we stood talking, we were suddenly startled by a commotion in the bushes and among the boles of the trees surrounding us, and simultaneously a hundred Kro-lu warriors appeared in a rough circle about us. They greeted Chal-az with a volley of questions as they approached slowly from all sides, their heavy bows fitted with long, sharp arrows. Upon Ajor and me they looked with covetousness in the one instance and suspicion in the other; but after they had heard Chal-az's story, their attitude was more friendly. A huge savage did all the talking.
He was a mountain of a man, yet perfectly proportioned.
"This is Al-tan the chief," said Chal-az by way of introduction.
Then he told something of my story, and Al-tan asked me many questions of the land from which I came. The warriors crowded around close to hear my replies, and there were many expressions of incredulity as I spoke of what was to them another world, of the yacht which had brought me over vast waters, and of the plane that had borne me Jo-oo-like over the summit of the barrier-cliffs. It was the mention of the hydroaeroplane which precipitated the first outspoken skepticism, and then Ajor came to my defense.
"I saw it with my own eyes!" she exclaimed. "I saw him flying through the air in battle with a Jo-oo. The Alus were chasing me, and they saw and ran away."
"Whose is this she?" demanded Al-tan suddenly, his eyes fixed fiercely upon Ajor.
For a moment there was silence. Ajor looked up at me, a hurt and questioning expression on her face. "Whose she is this?" repeated Al-tan.
"She is mine," I replied, though what force it was that impelled me to say it I could not have told; but an instant later I was glad that I had spoken the words, for the reward of Ajor's proud and happy face was reward indeed.
Al-tan eyed her for several minutes and then turned to me.
"Can you keep her?" he asked, just the tinge of a sneer upon his face.
I laid my palm upon the grip of my pistol and answered that I could. He saw the move, glanced at the butt of the automatic where it protruded from its holster, and smiled. Then he turned and raising his great bow, fitted an arrow and drew the shaft far back. His warriors, supercilious smiles upon their faces, stood silently watching him. His bow was the longest and the heaviest among them all. A mighty man indeed must he be to bend it; yet Al-tan drew the shaft back until the stone point touched his left forefinger, and he did it with consummate ease. Then he raised the shaft to the level of his right eye, held it there for an instant and released it.
When the arrow stopped, half its length protruded from the opposite side of a six-inch tree fifty feet away. Al-tan and his warriors turned toward me with expressions of immense satisfaction upon their faces, and then, apparently for Ajor's benefit, the chieftain swaggered to and fro a couple of times, swinging his great arms and his bulky shoulders for all the world like a drunken prize-fighter at a beach dancehall.
I saw that some reply was necessary, and so in a single motion, I drew my gun, dropped it on the still quivering arrow and pulled the trigger. At the sound of the report, the Kro-lu leaped back and raised their weapons; but as I was smiling, they took heart and lowered them again, following my eyes to the tree; the shaft of their chief was gone, and through the bole was a little round hole marking the path of my bullet.
It was a good shot if I do say it myself, "as shouldn't" but necessity must have guided that bullet; I simply had to make a good shot, that I might immediately establish my position among those savage and warlike Caspakians of the sixth sphere.
That it had its effect was immediately noticeable, but I am none too sure that it helped my cause with Al-tan. Whereas he might have condescended to tolerate me as a harmless and interesting curiosity, he now, by the change in his expression, appeared to consider me in a new and unfavorable light. Nor can I wonder, knowing this type as I did, for had I not made him ridiculous in the eyes of his warriors, beating him at his own game?
What king, savage or civilized, could condone such impudence?
Seeing his black scowls, I deemed it expedient, especially on Ajor's account, to terminate the interview and continue upon our way; but when I would have done so, Al-tan detained us with a gesture, and his warriors pressed around us.
"What is the meaning of this?" I demanded, and before Al-tan could reply, Chal-az raised his voice in our behalf.
