It will be remembered that Columbus wrote home to his royal patrons that the fish which abounded in the seas partook of the same novelty which characterized everything else in the New World. This was about four hundred years ago, before the great Genoese had discovered Cuba. "The fish," as he wrote, "rivaled the birds in tropical brilliancy of color, the scales of some of them glancing back the rays of light like precious stones, as they sported about the ships and flashed gleams of gold and silver through the clear water." The surface life of these translucent waters is also extremely interesting. Here the floating jelly-fish, called, from its phosphorescence, the glow-worm of the sea, is observed in great variety, sheltering little colonies of young fishes within its tentacles, which rush forth for a moment to capture some passing mite, and as quickly return again to their shelter. One takes up a handful of the floating gulf-weed and finds, within the pale yellow leaves and berries, tiny pipe-fish, sea-horses, and the little nest-building antennarius, thus forming a buoyant home for parasites, crabs, and mollusks, itself a sort of mistletoe of the ocean. The young of the mackerel and the herring glance all about just beneath the surface near the shore, like myriad pieces of silver. Now and again that particolored formation of marine life, the Portuguese man-of-war, is observed, its long ventral fins spread out like human fingers to steady it upon the surface of the water. Verily, the German scientist who says there is more of animal life beneath the surface of the sea than above it cannot be far amiss. This seems to be the more reasonable when we consider the relative proportions of land and water. The whole surface of the globe is supposed to have an area of about two hundred million square miles. Of these only about fifty millions are dry land. Within the harbor of Nassau the divisions of shoal and deep water presented most singular and clearly defined lines of color, azure, purple, and orange-leaf green,--so marked as to be visible half a mile away. All was beneath a sky so deeply and serenely blue as constantly to recall the arching heavens of middle India.
