It was easy to follow now, and St. George went breathlessly on past the rudely-hewn walls and giant pillars of that hidden way. He might have been lost with ease in any of the lower processes of the palace which they had that morning visited; but he could not be deceived about the chambers which he had once seen, and this subterranean course was new to him. Was it, he wondered, new to Olivia, and to Jarvo? Else why had it been omitted in that morning's search? And was this strange guide going on at random, or did he know--something? A suspicion leaped to St. George's mind that made his heart beat. The king--might he be down here after all, and might this weird old man know where? His own consciousness became chiefly conjecture, and every nerve was alert in the pursuit; not the less because he realized that if he were to lose this strange conductor who went on before, either in secure knowledge or in utter madness, he himself might wander for the rest of his life in that nether world. Past grim latchless doors sealing, with appropriate gestures, their forgotten secrets, past outlying passages winding into the heart of the mountain, past niches filled with shapeless crumbling rubbish they hurried--the mad old man and his bewildered pursuer. Twice the way turned, gradually narrowing until two could hardly have passed there, and at last apparently terminated in a short flight of steps. Old Malakh mounted with difficulty and St. George, waiting, saw him standing before a blank stone wall. Immediately and without effort the old man's scanty strength served to displace one of the wall's huge stones which hung upon a secret pivot and rolled noiselessly within. He stepped through the aperture, and St. George sprang behind him, watched his moment to cross the threshold, crouched in the leaping shadow of the displaced stone and looked--looked with the undistinguishing amazement that a man feels in the panorama of his dreams. The room was small and low and set with a circular bench, running about a central pillar. On the table was a confusion of things brilliantly phosphorescent, emitting soft light, and mingled with bulbs, coils and crucibles lying in a litter of egg-shells, feathers, ivory and paper. But it was not these that held St. George incredulous; it was the fire that glowed in their midst--a fire that leaped and trembled and blazed inextinguishable colour, smouldering, sparkling, tossing up a spray of strange light, lambent with those wizard hues of the pennons and streamers floating joyously from the dome of the Palace of the Litany--the fire from the subject hearts of a thousand jewels. There could be no doubting what he saw. There, flung on the table from the mouth of a carven casket and harbouring the captive light of ages gone, glittered what St. George knew would be the gems of the Hereditary Treasure of the kings of Yaque.
