A Floating City by Jules Verne

From Thursday night to Saturday the "Great Eastern" was crossing the Gulf Stream, the water of which is of a dark colour, the surface of the current forcing its way against the waters of the Atlantic, is even slightly convex. It is, in fact, a river running between two liquid shores, and one of the largest in the world, for it reduces the Amazon and Mississippi to mere brooks in comparison.

This day, the 5th of April, began with a magnificent sunrise, the waves glittered, and a warm south-west wind was wafted through the rigging. It was the beginning of the fine weather; the sun, which had clothed the fields of the continent with verdure, caused fresh costumes to bloom on board. Vegetation is sometimes behind-hand, but fashion never. Soon the Boulevards, filled with groups of promenaders, looked like the Champs Elysées on a fine Sunday afternoon in May.
