"When describing nature, a writer should seize upon small details, arranging them so that the reader will see an image in his mind after he closes his eyes. For instance: you will capture the truth of a moonlit night if you'll write that a gleam like starlight shone from the pieces of a broken bottle, and then the dark, plump shadow of a dog or wolf appeared. You will bring life to nature only if you don't shrink from similes that liken its activities to those of humankind."
