She crept quietly to within a few inches of him, and there remained immovable for half an hour. Suddenly she sprang towards him ; but he was on the look-out, and fought so vigorously that she was obliged to retreat. After this repulse she swam about carelessly for a time, as if searching for food was her only thought. But in ten or fifteen minutes she was back...
