“Each book records a journey made by walking, and each contains the natural objects and substances gathered along that particular path: seaweed, snakeskin, mica flakes, crystals of quartz, sea beans, lightning-scorched pine timber, the wing of a grey partridge, pillows of moss, worked flint, cubes of pyrite, pollen, resin, acorn cups, the leaves of holm oak, beech, elm.”
