Running at full speed, he came suddenly to a disused quarry that was full of water.  It had long been a familiar haunt as a bathing-pool.  Many a time in years past had he leaped off its precipitous margin into the deep water, and wantoned there in all the abandonment of exuberant youth.  The leap was about thirty feet, the depth of water probably greater.  Constant practice had rendered Miles so expert at diving and swimming that he had come to feel as much at home in the water as a New-Zealander.
