" Trees that are only trees by daylight are many and various other things at night. They are lurking, impossible monsters of the animal world or crouching human ruffians, of ferocious aspect and intent, depending upon their shape, size, color, distance from the beholder, and general state of well-being or decay. One's own well-being has some bearing on the matter. Strong nerves are needed to walk among them in the darkness. "
