"Canoes, too, are unobtrusive; they don't storm the natural world or ride over it, but drift in upon it as a part of its own silence. As you either care about what the land is or not, so do you like or dislike quiet things--sailboats, or rainy green mornings in foreign places, or a grazing herd, or the ruins of old monasteries in the mountains. . . . Chances for being quiet nowadays are limited."
