I went back every evening, after work, for nearly a year. I learned the meaning of the cud of a leaf and the glisten of wet pebbles, and the special significance of curves and angles. A great deal of the writing was unwritten. Plot three dots on a graph and join them; you now have a curve with certain characteristics. Extend that curve while maintaining the characteristics, and it has meaning, up where no dots were plotted. In just this way I learned to extend the curve of a grass-blade and of a protruding root, of the bent edges of wetness on a drying headstone. I quit smoking so I could sharpen my sense of smell, because the scent of earth after a rain has a clarifying effect on graveyard reading, as if the page were made whiter and the ink darker. I began to listen to the wind, and to the voices of birds and small animals, insects and people; because to the educated ear, every sound is filtered through the story written on graves, and becomes a part of it.
