No other sounds came to his ears than the dismal, bloodthirsty moanings of the beast ahead and the beast behind. The tunnel had led straight, from where he had entered it beneath the side of the rock furthest from the unscaleable cliffs, toward the mighty barrier that had baffled him so long. Now it was running almost level, and presently he noted a gradual ascent. The beast behind him was gaining upon him, crowding him perilously close upon the heels of the beast in front. Presently he should have to do battle with one, or both. More firmly he gripped his weapon. Now he could hear the breathing of the banth at his heels. Not for much longer could he delay the encounter. Long since he had become assured that the tunnel led beneath the cliffs to the opposite side of the barrier, and he had hoped that he might reach the moonlit open before being compelled to grapple with either of the monsters. The sun had been setting as he entered the tunnel, and the way had been sufficiently long to assure him that darkness now reigned upon the world without. He glanced behind him. Blazing out of the darkness, seemingly not ten paces behind, glared two flaming points of fire. As the savage eyes met his, the beast emitted a frightful roar and then he charged. To face that savage mountain of onrushing ferocity, to stand unshaken before the hideous fangs that he knew were bared in slavering blood-thirstiness, though he could not see them, required nerves of steel; but of such were the nerves of Carthoris of Helium. He had the brute’s eyes to guide his point, and, as true as the sword hand of his mighty sire, his guided the keen point to one of those blazing orbs, even as he leaped lightly to one side. With a hideous scream of pain and rage, the wounded banth hurtled, clawing, past him. Then it turned to charge once more; but this time Carthoris saw but a single gleaming point of fiery hate directed upon him. Again the needle point met its flashing target. Again the horrid cry of the stricken beast reverberated through the rocky tunnel, shocking in its torture-laden shrillness, deafening in its terrific volume. But now, as it turned to charge again, the man had no guide whereby to direct his point. He heard the scraping of the padded feet upon the rocky floor. He knew the thing was charging down upon him once again, but he could see nothing. Yet, if he could not see his antagonist, neither could his antagonist now see him. Leaping, as he thought, to the exact centre of the tunnel, he held his sword point ready on a line with the beast’s chest. It was all that he could do, hoping that chance might send the point into the savage heart as he went down beneath the great body. So quickly was the thing over that Carthoris could scarce believe his senses as the mighty body rushed madly past him. Either he had not placed himself in the centre of the tunnel, or else the blinded banth had erred in its calculations.
