When the awful rage of the storm had passed, and the barrier which he had repaired in the midst of the tempest hung like a broken arm across the gorge, Gilliatt, maddened by hunger, took advantage of the receding tide to go in search of crayfish. Half naked, and with his open knife between his teeth, he sprang from rock to rock. In hunting a crab he found himself once more in the mysterious grotto that glittered with jewel-like flowers. He noticed a fissure above the level of the water. The crab was probably there. He thrust in his hand as far as he was able, and groped about in that dusky aperture. Suddenly he felt himself seized by the arm. A strange, indescribable horror thrilled through him. Some living thing--thin, rough, flat, cold, slimy--had twisted itself round his naked arm. It crept upward towards his chest. Its pressure was like a tightening cord, its steady persistence like that of a screw. In less than a moment some mysterious spiral form had passed round his wrist and elbow, and had reached his shoulder. A sharp point penetrated beneath the arm-pit. Gilliatt recoiled; but he had scarcely power to move. He was, as it were, nailed to the place. With his left hand, which was disengaged, he seized his knife, and made a desperate effort to withdraw his arm. He only succeeded in disturbing his persecutor, which wound itself still tighter. It was supple as leather, strong as steel, cold as night. A second form--sharp, elongated, and narrow--issued out of the crevice, like a tongue out of monstrous jaws. It seemed to lick his naked body; then, suddenly stretching out, it became longer and thinner, as it crept over his skin, and wound itself round him. A terrible sense of anguish, comparable to nothing he had ever known, compelled all his muscles to contract. He felt upon his skin a number of flat, rounded points. It seemed as if innumerable suckers had fastened to his flesh, and were about to drink his blood. A third long, undulating shape issued from the hole in the rock, felt about his body, lashed round his ribs like a cord, and fixed itself there. There was sufficient light for Gilliatt to see the repulsive forms which had entangled themselves about him. A fourth ligature, but this one swift as an arrow, darted towards his stomach. These living things crept and glided about him; he felt the points of pressure, like sucking mouths, change their places from time to time. Suddenly a large, round, flattened, glutinous mass shot from beneath the crevice. It was the centre! The thongs were attached to it like spokes to the nave of a wheel. In the middle of this slimy mass appeared two eyes. The eyes were fixed on Gilliatt. He recognised the devil-fish. Gilliatt had but one resource--his knife.
