Gradually and mistily it became apparent that the Most Ancient One was holding something--some object clutched in the outflung folds of his robe as if for the sight, or what answered for sight, of the cloaked Companions. It was a large sphere, or apparent sphere, of some obscurely iridescent metal, and as the Guide put it forward a low, pervasive half-impression of _sound_ began to rise and fall in intervals which seemed to be rhythmic even though they followed no rhythm of Earth. There was a suggestion of chanting--or what human imagination might interpret as chanting. Presently the quasi-sphere began to grow luminous, and as it gleamed up into a cold, pulsating light of unassignable color, Carter saw that its flickerings conformed to the alien rhythm of the chant. Then all the mitered, scepter-bearing Shapes on the pedestals commenced a slight, curious swaying in the same inexplicable rhythm, while nimbuses of unclassifiable light--resembling that of the quasi-sphere--played around their shrouded heads. The Hindoo paused in his tale and looked curiously at the tall, coffin-shaped clock with the four hands and hieroglyphed dial, whose crazy ticking followed no known rhythm of Earth. "You, Mr. de Marigny," he suddenly said to his learned host, "do not need to be told the particularly alien rhythm to which those cowled Shapes on the hexagonal pillars chanted and nodded. You are the only one else--in America--who has had a taste of the Outer Extension. That clock--I suppose it was sent you by the Yogi poor Harley Warren used to talk about--the seer who said that he alone of living men had been to Yian-Ho, the hidden legacy of eon-old Leng, and had borne certain things away from that dreadful and forbidden city. I wonder how many of its subtler properties you know? If my dreams and readings be correct, it was made by those who knew much of the First Gateway. But let me go on with my tale." * * * * * At last, continued the Swami, the swaying and the suggestion of chanting ceased, the lambent nimbuses around the now drooping and motionless heads faded, while the cloaked shapes slumped curiously on their pedestals. The quasi-sphere, however, continued to pulsate with inexplicable light. Carter felt that the Ancient Ones were sleeping as they had been when he first saw them, and he wondered out of what cosmic dreams his coming had aroused them. Slowly there filtered into his mind the truth that this strange chanting ritual had been one of instruction, and that the Companions had been chanted by the Most Ancient One into a new and peculiar kind of sleep in order that their dreams might open the Ultimate Gate to which the silver key was a passport. He knew that in the profundity of this deep sleep they were contemplating unplumbed vastnesses of utter and absolute outsideness, and that they were to accomplish that which his presence had demanded.
