Saturday, April, 1852. There was a fervor in the sky as of an August noon, although the clocks of the city would presently strike five. Dazzling white clouds, about to show the earliest flush of the sun's decline, beamed down upon a turbid river harbor, where the water was deep so close inshore that the port's unbroken mile of steamboat wharf nowhere stretched out into the boiling flood. Instead it merely lined the shore, the steamers packing in bow on with their noses to it, their sterns out in the stream, their fenders chafing each other's lower guards.
