might have made everything all right again. On the march, or during halts, Dian refused consistently to notice me—when her eyes wandered in my direction she looked either over my head or directly through me. At last I became desperate, and determined to swallow my self-esteem, and again beg her to tell me how I had offended, and how I might make reparation. I made up my mind that I should do this at the next halt. We were approaching another range of mountains at the time, and when we reached them, instead of winding across them through some high-flung pass we entered a mighty natural tunnel—a series of labyrinthine grottoes, dark as Erebus. The guards had no torches or light of any description. In fact we had seen no artificial light or sign of fire since we had entered Pellucidar. In a land of perpetual noon there is no need of light above ground, yet I marveled that they had no means of lighting their way through these dark, subterranean passages. So we crept along at a snail’s pace, with much stumbling and falling—the guards keeping up a singsong chant ahead of us, interspersed with certain high notes which I found always indicated rough places and turns. Halts were now more frequent, but I did not wish to speak to Dian until I could see from the expression of her face how she was receiving my apologies. At last a faint glow ahead forewarned us of the end of the tunnel, for which I for one was devoutly thankful. Then at a sudden turn we emerged into the full light of the noonday sun. But with it came a sudden realization of what meant to me a real catastrophe—Dian was gone, and with her a half-dozen other prisoners. The guards saw it too, and the ferocity of their rage was terrible to behold. Their awesome, bestial faces were contorted in the most diabolical expressions, as they accused each other of responsibility for the loss. Finally they fell upon us, beating us with their spear shafts, and hatchets. They had already killed two near the head of the line, and were like to have finished the balance of us when their leader finally put a stop to the brutal slaughter. Never in all my life had I witnessed a more horrible exhibition of bestial rage—I thanked God that Dian had not been one of those left to endure it. Of the twelve prisoners who had been chained ahead of me each alternate one had been freed commencing with Dian. Hooja was gone. Ghak remained. What could it mean? How had it been accomplished? The commander of the guards was investigating. Soon he discovered that the rude locks which had held the neckbands in place had been deftly picked.
