"The end of summer," said Eleanor softly. "Listen to the beat of our horses' hoofs--'tump-tump-tump-a-tump.' Have you ever been feverish and had all noises divide into 'tump-tump-tump' until you could swear eternity was divisible into so many tumps? That's the way I feel--old horses go tump-tump.... I guess that's the only thing that separates horses and clocks from us. Human beings can't go 'tump-tump-tump' without going crazy."
