I was even more amazed at his words than if he had told me of my every movement and action since I entered Salceda’s shop at Vigo. For it was obvious, certain, that he did _not_ read my thoughts, that I was _not_ hypnotized. And I was convinced, even though my reason told me I should not be, that Nohul Voh possessed an uncanny, an almost supernatural power. If he could look into the past, might he not be able to look into the future? Was it not possible--even certain--that he had accomplished what countless men had dreamed of doing? Memories of theories of the fourth dimension, of extravagant fiction, of impossible, wholly imaginary stories raced through my brain. But none, nothing I had ever heard or read was as seemingly unreal, impossible and fictional as what was actually being demonstrated to me in this ancient city of the Mayas. * * * * * AT last I found my voice. “I am convinced, O, Nohul Voh,” I declared. “Whatever you may show me, I will believe.” He smiled. “Then, behold!” he exclaimed, removing the cover from the incense burner and stepping quickly to one side. For a brief moment I saw nothing. Then a thin, luminous wisp, similar to smoke in the beam of an electric light, rose from the great earthen vessel. Slowly it spread, mushrooming out, undulating, unfolding, until it formed a great cloud completely concealing the room beyond it. I gazed at it, watched it with fascinated eyes, hardly knowing what to expect. Lighter and darker areas appeared upon the now stationary bank of vapor. Patches of brown, of green, of blue appeared and slowly, little by little, like a dissolving view, a picture developed before my eyes. I recognized the picture instantly; it was the valley beyond the Cave of the Bats! There were the towering mountains, there was the cliff with the huge stone image of Kukulcan cut deeply into its surface. I seemed to be moving towards it. The valley and the hills came nearer and nearer. A stream dashed, foaming, through the valley. Beside a shaded pool a bare ledge jutted up, and upon the surface of the water-polished rock I saw the symbol that Itza had discovered in my codex--the symbol of Kukulcan, the foot and the reed. * * * * * [Illustration: I recognized the picture instantly--it was the valley beyond the Cave of the Bats!] * * * * *
