As a matter of fact, his mind refused the task on which he was endeavoring to focus his attention. Despite his utmost efforts, his thoughts would return to Elaine. He would have given almost his hope of eternity to secure her absolute comfort and freedom from anxiety. And, inasmuch as the tiger was responsible for much of her worry, his mind was made up that a trial should be made to slay the brute without another day's delay.... It is always so easy to plan! He was finally staring straight into the fire, though his hand still rested on the parchment and the paper. The flames sank lower and lower, wavering finally like dull red spear-heads among the glowing embers. At some fancied sound he turned sharply about, to peer through the darkness of the trail. All appeared as silent and calm as the grave. He wondered if, perhaps, Elaine had arisen to come to her door. She was not to be seen at the indistinct entrance of her cave. He turned once more to stir his fire--then wheeled like one on a pivot. His senses had not been deceived. Beyond, in the darkness, a few feet only from the cavern occupied by Elaine, two blazing coals had been fixed like twin stars by his movement. A sudden recollection that he had failed to close the gap in the wall swept hotly and accusingly through him. Some beast of the jungle had passed the barrier, perhaps to enter the very cave that the wall had been built to protect! With a note that broke the stillness abruptly, Grenville caught up a flaming branch of wood from the mass of embers in the fire, and sprang to the path to the cavern. The prowling animal stood for a moment undecided, then started as if to spring before the oncoming man to the shelter of Elaine's rock retreat, doubtless to turn there in desperation for a mad encounter in the dark. But, perhaps by a yard, the man was there before him. The brute, even then, refused to retreat towards the trail by which it had come. It leaped towards the place where Grenville made his bed--a shadowy form that he knew at last was not the arrogant tiger. It turned for a moment in the mouth of the cave, as if aware this smaller retreat was too shallow for adequate shelter. But before the man could crack his fiery brand upon the creature's head, it leaped wildly past him, growling a savage protest, and reluctantly retreated towards the trail. One more attempt it made, even then, to escape by Grenville's active form, and regain the larger cavern. But his fierce, hot rushes were not to be withstood. It finally turned with another sort of bellow, and cowered uncertainly upon the downward path. After it no less desperately than before, Sidney plunged along the steep descent, his firebrand brightly glowing in the wind. A whine of fear escaped the jungle creature as he slunk at last through Grenville's gate to the outer precincts of the wall.
