Of all the hard-working people on the earth, there are none so serviceable to her neighbours as the moon. She lights lovers and thieves. She keeps watch-dogs waking. She is a constant resource to poets and romance-writers. She helps the compounders of almanacks amazingly. She has something to do with the weather, and the tides, and the harvest; and in short she has a finger in every man's pie, and probably more or less effect upon every man's brain. She is a charming creature in all her variations. Her versatility is not the offspring of caprice; and she is constant in the midst of every change.
