They were all much interested in me and examined my clothing and equipment carefully, handling and feeling and smelling of each article. I learned from them that their people were known as Band-lu, or spear-men; Tsa’s race was called Sto-lu—hatchet-men. Below these in the scale of evolution came the Bo-lu, or club-men, and then the Alus, who had no weapons and no language. In that word I recognized what to me seemed the most remarkable discovery I had made upon Caprona, for unless it were mere coincidence, I had come upon a word that had been handed down from the beginning of spoken language upon earth, been handed down for millions of years, perhaps, with little change. It was the sole remaining thread of the ancient woof of a dawning culture which had been woven when Caprona was a fiery mount upon a great land-mass teeming with life. It linked the unfathomable then to the eternal now. And yet it may have been pure coincidence; my better judgment tells me that it is coincidence that in Caspak the term for speechless man is Alus, and in the outer world of our own day it is Alalus. The comely woman of whom I spoke was called So-ta, and she took such a lively interest in me that To-jo finally objected to her attentions, emphasizing his displeasure by knocking her down and kicking her into a corner of the cavern. I leaped between them while he was still kicking her, and obtaining a quick hold upon him, dragged him screaming with pain from the cave. Then I made him promise not to hurt the she again, upon pain of worse punishment. So-ta gave me a grateful look; but To-jo and the balance of his women were sullen and ominous. Later in the evening So-ta confided to me that she was soon to leave the tribe.
