in the voice of the serpent.
Tarvin jumped, and stayed still. Fibby's neigh came faintly now. The dawn-wind blew through the gap in the wall, and Tarvin wiped his forehead with a deep sigh of relief. He would do no more till the light came. This was the hour to eat and drink; also to stand very still, because of that voice from the ground.
He pulled food and a flask from his pocket, and, staring before him in every direction, ate hungrily. The loom of the night lifted a little, and he could see the outline of some great building a few yards away. Beyond this were other shadows, faint as the visions in a dream--the shadows of yet more temples and lines of houses; the wind, blowing among them, brought back a rustle of tossing hedges.
The shadows grew more distinct: he could see that he was standing with his face to some decayed tomb. Then his jaw fell, for, without warning or presage, the red dawn shot up behind him, and there leaped out of the night the city of the dead. Tall-built, sharp-domed palaces, flushing to the colour of blood, revealed the horror of their emptiness, and glared at the day that pierced them through and through.
The wind passed singing down the empty streets, and, finding none to answer, returned, chasing before it a muttering cloud of dust, which presently whirled itself into a little cyclone-funnel, and lay down with a sigh.
A screen of fretted marble lay on the dry grass, where it had fallen from some window above, and a gecko crawled over it to sun himself. Already the dawn flush had passed. The hot light was everywhere, and a kite had poised himself in the parched blue sky. The day, new-born, might have been as old as the city. It seemed to Tarvin that he and it were standing still to hear the centuries race by on the wings of the purposeless dust.
As he took his first step into the streets, a peacock stepped from the threshold of a lofty red house, and spread his tail in the splendour of the sun. Tarvin halted, and with perfect gravity took off his hat to the royal bird, where it blazed against the sculptures on the wall, the sole living thing in sight.
The silence of the place and the insolent nakedness of the empty ways lay on him like a dead weight. For a long time he did not care to whistle, but rambled aimlessly from one wall to another, looking at the gigantic reservoirs, dry and neglected, the hollow guard-houses that studded the battlements, the time-riven arches that spanned the streets, and, above all, the carven tower with a shattered roof that sprang a hundred and fifty feet into the air, for a sign to the country-side that the royal city of Gunnaur was not dead, but would one day hum with men.
It was from this tower, encrusted with figures in high relief of beast and man, that Tarvin, after a heavy climb, looked out on the vast sleeping land in the midst of which the dead city lay. He saw the road by which he had come in the night, dipping and reappearing again over thirty miles of country, saw the white poppy-fields, the dull-brown scrub, and the unending plain to the northward, cut by the shining line of the rail. From his eyrie he peered forth as a man peers from a crow's-nest at sea; for, once down there below in the city, all view was cut off by the battlements that rose like bulwarks. On the side nearest to the railroad, sloping causeways, paved with stone, ran down to the plain under many gates, as the gangway of a ship when it is let down, and through the gaps in the walls--time and the trees had torn their way to and fro--there was nothing to be seen except the horizon, which might have been the deep sea.
He thought of Fibby waiting in the scrub for his breakfast, and made haste to descend to the streets again. Remembering the essentials of his talk with Estes as to the position of the Cow's Mouth, he passed up a side lane, disturbing the squirrels and monkeys that had taken up their quarters in the cool dark of the rows of empty houses. The last house ended in a heap of ruins among a tangle of mimosa and tall grass, through which ran a narrow foot-track.
Tarvin marked the house as the first actual ruin he had seen. His complaint against all the others, the temples and the palaces, was that they were not ruined, but dead--empty, swept, and garnished, with the seven devils of loneliness in riotous possession. In time--in a few thousand years perhaps--the city would crumble away. He was distinctly glad that one house at least had set the example.
The path dropped beneath his feet on a shelf of solid rock that curved over like the edge of a waterfall. Tarvin took only one step, and fell, for the rock was worn into deep gutters, smoother than ice, by the naked feet of millions who had trodden that way for no man knew how many years. When he rose he heard a malignant chuckle, half suppressed, which ended in a choking cough, ceased, and broke out anew. Tarvin registered an oath to find that scoffer when he had found the necklace, and looked to his foothold more carefully. At this point it seemed that the Cow's Mouth must be some sort of disused quarry fringed to the lips with rank vegetation.
All sight of what lay below him was blocked by the thick foliage of trees that leaned forward, bowing their heads together as night-watchers huddle over a corpse. Once upon a time there had been rude steps leading down the almost sheer descent, but the naked feet had worn them to glassy knobs and lumps, and blown dust had made a thin soil in their chinks. Tarvin looked long and angrily, because the laugh came from the bottom of this track, and then, digging his heel into the mould, began to let himself down step by step, steadying himself by the tufts of grass. Before he had realised it, he was out of reach of the sun, and neck deep in tall grass. Still there was a sort of pathway under his feet, down the almost perpendicular side. He gripped the grass, and went on. The earth beneath his elbows grew moist, and the rock where it cropped out showed rotten with moisture and coated with moss. The air grew cold and damp. Another plunge downward revealed to him what the trees were guarding, as he drew breath on a narrow stone ledge. They sprang from the masonry round the sides of a square tank of water so stagnant that it had corrupted past corruption, and lay dull blue under the blackness of the trees. The drought of summer had shrunk it, and a bank of dried mud ran round its sides. The head of a sunken stone pillar, carved with monstrous and obscene gods, reared itself from the water like the head of a tortoise swimming to land. The birds moved in the sunlit branches of the trees far overhead. Little twigs and berries dropped into the water, and the noise of their fall echoed from side to side of the tank that received no sunlight.
The chuckle that had so annoyed Tarvin broke out again as he listened. This time it was behind him, and wheeling sharply, he saw that it came from a thin stream of water that spurted fitfully from the rudely carved head of a cow, and dripped along a stone spout into the heavy blue pool. Behind that spout the moss-grown rock rose sheer. This, then, was the Cow's Mouth.
The tank lay at the bottom of a shaft, and the one way down to it was that by which Tarvin had come--a path that led from the sunlight to the chill and mould of a vault.
'Well, this is kind of the King, anyhow,' he said, pacing the ledge cautiously, for it was almost as slippery as the pathway on the rocks. 'Now, what's the use of this?' he continued, returning. The ledge ran only round one side of the tank, and, unless he trusted to the mudbanks on the other three, there was no hope of continuing his exploration further. The Cow's Mouth chuckled again, as a fresh jet of water forced its way through the formless jaws.
'Oh, dry up!'he muttered impatiently, staring through the half light that veiled all.
He dropped a piece of rock on the mud under the lip of the ledge, then tested it with a cautious foot, found that it bore, and decided to walk round the tank. As there were more trees to the right of the ledge than to the left, he stepped off on the mud from the right, holding cautiously to the branches and the tufts of grass in case of any false step.
When the tank was first made its rock walls had been perfectly perpendicular, but time and weather and the war of the tree roots had broken and scarred the stone in a thousand places, giving a scant foothold here and there.
Tarvin crept along the right side of the tank, resolved, whatever might come, to go round it. The gloom deepened as he came directly under the largest fig-tree, throwing a thousand arms across the water, and buttressing the rock with snake-like roots as thick as a man's body. Here, sitting on a root, he rested and looked at the ledge. The sun, shooting down the path that he had trampled through the tall grass, threw one patch of light on the discoloured marble of the ledge and on the blunt muzzle of the cow's head but where Tarvin rested under the fig-tree there was darkness, and an intolerable scent of musk.
