A sound of horror broke from the Dyak's lips as he rolled on the earth with the skeleton rattling down upon him. But a brief time only was he prostrate there with his terror. Uttering screams as shrill as a woman's and darting swiftly to meet his crew of men, who suddenly swarmed from the thicket, he headed a wild, fanatic pursuit where Grenville was speeding for the terrace. CHAPTER XXXIII THE GIRL BEHIND THE GUN Alone on the hill, and already strung to the highest tension of dread by Grenville's long absence, after what he had said of a prompt return, Elaine had been struck with alarm to the core of her being, as the various sounds came clearly up from the jungle about the disintegrated wreck. It was fears for Sidney, not for herself, that had finally possessed her fluttering heart as the muffled shot and subsequent cries floated uncertainly from down there in the darkness. She knew that Grenville had no gun, and was, therefore, certain it was he who must have suffered a wound. With a blazing torch she had run to the edge of the terrace, to light Sidney home, if, by any bare chance, he had escaped. She was there, transfixed by apprehension, when at length, with cries like a pack of wolves, the Dyaks came racing towards the clearing. Meantime Grenville had gained a considerable lead of the devils on his heels, and, on passing the spring, had caught a glimpse of Elaine with her brand of fire. He paused for a second to shout essential directions, lest she might have forgotten in her plight. "Don't fire, Elaine, till you see them on the trail!" With that he darted abruptly to the left, for the animal trail that would lead him to his ladder. He had no more than gained it when, with a chorus of demoniac yells and screams of triumph, the straggling pursuers broke madly into the clearing and darted across it for the trail. Even then, afraid that Elaine might fail to perform her allotted task, Grenville sped up his ladder like a creature of the wild, and came to the end of his platform. The Dyaks were immediately storming the barrier, the breach of which was promptly discovered, and Sidney's alarm was jerkily resounding. Like a spirit of maternity, nerved to any ordeal by the sense of protecting one she loved, Elaine crouched low beside the cannon, her dilated eyes intent upon the trail. She had clung to a hope that Grenville might yet appear in time to take charge of the gun. But suddenly now, to her terror, four or more figures darkly appeared on the ledge above the gate, coming swiftly towards her position. She thrust the torch desperately down upon the fuse, saw the powder spew out a shower of sparks, and rolled and tumbled hotly from the place. She was suddenly agonized by the thought that the thing would fail, but Grenville had barely reached the solid rock when the cannon abruptly thundered.
