Norris hitched forward and reloaded the rifle. Then he advanced slowly between the bushes on the alert for a charge from the wounded bull; but nothing stirred. No sound came to his ears except the soft padding noise of his horse's hoofs upon the turf. There was not a crackle of the brushwood, and the trees seemed carved out of metal. He rode through absolute silence in a suspension of all movement. Once his horse trod upon a bough, and the snapping of the twigs sounded like so many cracks of a pistol. At first the silence struck Norris as merely curious, a little later as very lonesome. Once or twice he stopped his horse with a sudden jerk of the reins, and sat crouched forwards with his neck outstretched, listening. Once or twice he cast a quick, furtive glance over his shoulder to make certain that no one stood between himself and the entrance to the hollow. He forgot the buffalo; he caught himself labouring his breath, and found it necessary to elaborately explain the circumstance in his thoughts on the ground of heat.
The next moment he began to plead this heat not merely as an excuse for his uneasiness, but as a reason for returning to camp. The heat was intense, he argued. Above him the light of an African midday sun poured out of a brassy sky into a sort of inverted funnel, and lay in blinding pools upon the scattered slabs of rock. Within the hollow, every cup of the innumerable flowers which tapestried the cliffs seemed a mouth breathing heat. He became possessed with a parching thirst, and he felt his tongue heavy and fibrous like a dried fig. There was, however, one obstacle which prevented him from acting upon his impulse, and that obstacle was his sense of shame. It was not so much that he thought it cowardly to give up the chase and quietly return, but he knew that the second after he had given way, he would be galloping madly towards the entrance in no child's panic of terror. He finally compromised matters by dropping the reins upon his horse's neck in the unformulated hope that the animal would turn of its own accord; but the horse kept straight on.
As Norris drew towards the innermost wall of granite, there was a quick rustle all across its face as though the screen of shrubs and flowers had been fluttered by a draught of wind. Norris drew himself erect with a distinct appearance of relief, loosened the clench of his fingers upon his rifle, and began once more to search the bushes for the buffalo.
For a moment his attention was arrested by a queer object lying upon the ground to his left. It was in shape something like a melon, but bigger, and it seemed to be plastered over with a black mould. Norris rode by it, turned a corner, and then with a gasp reined back his horse upon its haunches. Straight in front of him a broken rifle lay across the path.
Norris stood still, and stared at it stupidly. Some vague recollection floated elusively through his brain. He tried to grasp and fix it clearly in his mind. It was a recollection of something which had happened a long while ago, in England, when he was at school. Suddenly, he remembered. It was not something which had happened, but something he had read under the great elm trees in the close. It was that passage in Robinson Crusoe which tells of the naked footprint in the sand.
Norris dismounted, and stooped to lift the rifle; but all at once he straightened himself, and swung round with his arms guarding his head. There was no one, however, behind him, and he gave a little quavering laugh, and picked up the rifle. It was a heavy lo-bore Holland, a Holland with a single barrel, and that barrel was twisted like a corkscrew. The lock had been wrenched off, and there were marks upon the stock—marks of teeth, and other queer, unintelligible marks as well.
Norris held the rifle in his hands, gazing vacantly straight ahead. He was thinking of the direction in which he had come, southwest, and of the stream which he had crossed, and of the patch of trampled mud, where track obliterated track. He dropped the rifle. It rang upon a stone, and again the screen of foliage shivered and rustled. Norris, however, paid no attention to the movement, but ran back to that object which he had passed, and took it in his hands.
It was oval in shape, being slightly broader at one end than the other. Norris drew his knife and cleaned the mould from one side of it. To the touch of the blade it seemed softer than stone, and smoother than wood. "More like bone," he said to himself. In the side which he had cleaned, there was a little round hole filled up with mould. Norris dug his knife in and scraped round the hole as one cleans a caked pipe. He drew out a little cube of mud. There was a second corresponding hole on the other side. He turned the narrower end of the thing upwards. It was hollow, he saw, but packed full of mould, and more deliberately packed, for there were finger-marks in the mould. "What an aimless trick!" he muttered vaguely.
He carried the thing back to the rifle, and, comparing them, understood those queer marks upon the stock. They were the mark of fingers, of human fingers, impressed faintly upon the wood with superhuman strength. He was holding the rifle in his hands and looking down at it; but he saw below the rifle, and he saw that his knees were shaking in a palsy.
On an instant he tossed the rifle away, and laughed to reassure himself—laughed out boldly, once, twice; and then he stopped with his eyes riveted upon the granite wall. At each laugh that he gave the shrubs and flowers rippled, and shook the sunlight from their leaves. For the first time he remarked the coincidence as something strange. He lifted up his face, but not a breath of air fanned it; he looked across the hollow, the trees and bushes stood immobile. He laughed a third time, louder than before, and all at once his laughter got hold of him; he sent it pealing out hysterically, burst after burst, until the hollow seemed brimming with the din of it. His body began to twist; he beat time to his laughter with his feet, and then he danced. He danced there alone in the African sunlight faster and faster, with a mad tossing of his limbs, and with his laughter grown to a yell. And as though to keep pace with him, each moment the shiver of the foliage increased. Up and down, crosswise and breadthwise, the flowers were tossed and flung, while their petals rained down the cliff's face in a purple storm. It appeared, indeed, to Norris that the very granite walls were moving.
