spreading itself clearly forward, as soon as the moon was free. With the airy space that flowed from her came out the whole eastern sea-board, liquid and distinct, as if beyond either bow of the lifting Indiaman one sharp finger of a pair of compasses had flashed round, drawing a semicircle upon the dull background, still cloudy, glimmering, and obscure. From the waves that undulated towards her stern, the ship was apparently entering upon a smoother zone, where the small surges leapt up and danced in moonshine, resembling more the current of some estuary in a full tide. To north-westward, just on the skirts of the dark, one wing of a large, soft-gray vapour was newly smitten by the moon-gleam; and over against it on the south-east, where the long fog-bank sank away, there stretched an expanse of ocean which, on its farthest verge, gave out a tint of the most delicate opal blue. The ship, to the south-westward of the Azores, and going large before the trade-wind, was now passing into the great Gulf Stream which there runs to the south-east; even the passengers on deck were sensible of the rapid transition with which the lately cold breeze became warmer and fitful, and the motion of the vessel easier. They were surprised, on looking into the waves alongside, to perceive them struggling, as it were, under a trailing net-work of sea-weed; which, as far as one could distinctly see, appeared to keep down the masses of water like so much oil--flattening their crests, neutralising the force of the wind, and communicating a strangely sombre green to the heaving element. In the winding track of the ship's wake the eddies now absolutely blazed: the weeds she had crushed down rose to the surface again in gurgling circles of flame, and the showers of sparks came up seething on either side amongst the stalks and leaves: but as the moonlight grew more equally diffused it was evident she was only piercing an arm of that local weed-bed here formed, like an island, in the _bight_ of the stream. Farther ahead were scattered patches and bunches of the true Florida Gulf-weed, white and moss-like; which, shining crisp in the level moonlight, and tipping the surges as it floated past, gave them the aspect of hoary-bearded waves, or the garlanded horses of Neptune. The sight still detained the captain's party on deck, and some of the ladies innocently thought these phenomena indicative of the proximity of land.
