Guy De Maupassant said this quote

I have an immoderate passion for water; for the sea, though so vast, so restless, so beyond one's comprehension; for rivers, beautiful, yet fugitive and elusive; but especially for marshes, teeming with all that mysterious life of the creatures that haunt them. A marsh is a whole world within a world, a different world, with a life of its own, with its own permanent denizens, its passing visitors, its voices, its sounds, its own strange mystery.
