It looked like the Southern Cross worked out in perfectly white stones on the surface of the sand near the water-hole. Stobart did not run. An uncanny feeling came over him. Those hoof-marks, and now this design—surely the thing must be the work of man.
Suddenly he stumbled. His bare feet caught in something and he tripped. He looked down at his toe. It was cut and bleeding slightly. He went back to find the thing which had tripped him.
It was the blade of a shovel!
One edge was sticking up. With shaking hands Stobart pulled it out of the sand. It came away easily, for the handle was burnt. He groped about near it and uncovered, one after another, a gold-washing dish, a pick-head, a couple of wedges, and a hammer. The sand had drifted over them and made a mound. Then he laid bare a truly gruesome sight—charred embers of wood and half-burnt human bones.
Stobart did not disturb the sand any more. He knew now why the gold prospectors, who had penetrated into the Musgrave fastnesses in search of the wealth which was reputed to be there, had never returned. Would he ever return, he wondered. The place was haunted by the spirits of the murdered dead, and was guarded by black devils in human form. Even now one of them might be watching him, waiting an opportunity of adding his bones to the collection which the sand had covered up.
He rose to his feet. He was thirsty, and the sight he had just seen made him want to soak his whole body in the cool clean water of the pool. He laughed harshly. What were all these fancies which were coming into his head? He would not give way to them. This life in a blacks' camp was upsetting his nerves. What were a few dead men after all? He had seen plenty of them. He was alive and would soon escape from this outpost of death. He laughed again. The rocky walls sent back an echo of his laugh. It sounded like an evil spirit mocking him. He walked a few paces, till he was near those white things which had been laid out so carefully in the design of the Southern Cross. He looked at them. He looked again, astonished beyond measure. Yes! No! Yes, they were!
They were human skulls—white men's skulls!
Stobart staggered away. He lay down on the edge of the water. He needed its cool touch to save him from madness. He drank deep, deep satisfying draughts. He bathed his head and face and plunged his arms in it, splashing the life-giving drops over his naked chest. The sense of horror gradually began to leave him, and he realized that he had reached the object of his search. He had found the Musgrave gold-mine. From where he lay he looked up at the boulder-strewn knoll behind the water-hole. Even at the distance of several yards he could see that every boulder was more richly studded with the precious metal than any he had ever seen. It did not surprise him. The events of the last hour had robbed him of the power to be surprised. He just looked up at all that wealth and knew it was his—his, if only he could take it away.
He turned his head and looked at the skulls. Each bleached remains of what had once been the head of a courageous man was looking at him out of empty eye-sockets. The jaws had been propped open and seemed to be laughing with ghastly dead mirth into the face of the living man. Stobart's imagination began to play tricks with him, for when he turned his eyes away, the glances of the skulls seemed to turn also.
He plunged his head once more into water and leaned over till his chest and arms were covered. His hands groped about in the cool sand, and when he pulled them out again they were full of wet sand. The sun's rays caught it and struck a thousand flashes from the grains. They looked unusually yellow and bright. Stobart turned the sand over and let it run between his fingers. It was like grains of sunlight. He thought that his overwrought nerves were deceiving him, and picked up another handful. It behaved exactly in the same way. It glinted and flashed yellow in a way that no sand could ever do. All at once it dawned upon him. This was no trick of sunlight on wet sand. This was no make-believe of tired nerves.
