"Come!" he growled. "Come, little hakim!" Then he turned on his heel at once, as if afraid of being twitted with desertion. He seemed to want to get outside, where he could keep out of range of words, yet not to wish to seem unfriendly.

But King made no effort to speak to him, following in silence out on to the dark ledge above the waterfall and noticing that the guard with the boils was back again on duty. He grinned evilly out of a shadow as King passed.

"Make an end!" he advised, spitting over the Cliff into thunderous darkness to illustrate the suggestion. "Jump, hakim, before a worse thing happens!"

To add further point be kicked a loose stone over the edge, and the movement caused him to bend his neck and so inadvertently to hurt his boils. He cursed, and there was pity in King's voice when he spoke next.

"Do they hurt thee?"

"Aye, like the devil! Khinjan is a place of plagues!"

"I could heal them," King said, passing on, and the man stared hard.

"Come!" boomed Ismail through the darkness, shaking the torch to make it burn better and beckoning impatiently, and King hurried after him, leaving behind a savage at the cave mouth who fingered his sores and wondered, muttering, leaning on a rifle, muttering and muttering again as if he had seen a new light.

Instead of waiting for King to catch up, Ismail began to lead the way at great speed along a path that descended gradually until it curved round the end of the chasm and plunged into a tunnel where the darkness grew opaque. In the tunnel the torch's smoke cast weird shadows on walls and roof, and the fitful light only confused, so that Ismail slowed down and let him come up close.

Then for thirty minutes he led swiftly down a crazy devil's stairway of uneven boulders, stopping to lend a hand at the worst places, but everlastingly urging him to hurry. They were both breathless, and King was bruised in a dozen places when they reached level going at least six or seven hundred feet below the cave from which they started.

Then the hell-mouth gloom began to grow faintly luminous, and the waterfall's thunder burst on their ears from close at hand. They emerged into fresh wet air and a sea of sound, on a rock ledge like the one above. Ismail raised the torch and waved it. The fire and smoke wandered up, until they flattened on a moving opal dome, that prisoned all the noises in the world.

"Earth's Drink!" he announced, waving the torch and then shutting his mouth tight, as if afraid to voice sacrilege.
