This quote from Mark Twain is probably well-known, but I had never come across it before.
How beautiful is the whole region, for form, and grouping, and opulence, and freshness of foliage, and variety of colour, and grace and shapeliness of the hills, the capes, the promontories; and then, the splendour of the sunlight, the dim, rich distances, the charm of the water-glimpses! And it was in this paradise that the yellow-liveried convicts were landed, and the Corps-bandits quartered, and the wanton slaughter of the kangaroo-chasing black innocents consummated on that autumn day in May, in the brutish old time. It was all out of keeping with the place, a sort of bringing of heaven and hell together.
Mark Twain, Following the Equator, 1897
