It is not easy to obtain a piece of living coral, for the purpose of studying its wondrous structure, and admiring its exceeding beauty. The great depth at which the mysterious little animals dwell in the ocean, secures them against the mere amateur fisherman; and the professional coral-fisher in the Mediterranean, the son of superstitious races of Southern Italy, is even extremely reluctant to admit outsiders into the secrets of his trade. However, they seem only to seek very superficially. As a proof of this assertion, we cite the following example: The United States Steamer Gettysburg, while on her way from Fayal to Gibraltar, recently made a discovery of considerable importance, in the shape of an immense coral bank (hitherto totally unknown), in latitude 36° 30´, longitude 11° 28´. Partial surveys were made, and the least depth of water noted was one hundred and eighty feet, which, in mid-ocean, is very significant. Twenty miles west of the bank, the sounding line marks sixteen thousand five hundred feet, and between the bank and Cape St. Vincent, twelve thousand feet. The commander of the Gettysburg believes that in some portions the coral rises to the surface. How such a reef, in a part of the ocean which is constantly traversed by vessels, can have remained undiscovered is almost inexplicable. It is also stated that the bank is rich in valuable coral of light pink shades of color. [Sidenote: CORAL FISHING.] The coral fishing is done in this way: a large net is fastened by a stout rope to the stern of the vessel. At the end of this rope hangs first an iron cross, consisting of two hollow tubes, laid cross-wise, through which strong ash poles have been thrust, and to this are fastened a number of old sardine-nets, no longer fit for their first purpose, and countless ends and bits of wide-meshed pieces of rope, as thick as a finger—the whole apparatus a mass of rags and rotten network. But the more such wretched-looking pieces of network the fisher can fasten to his iron cross, the better are his chances. When the sea is perfectly quiet, he lets them sink down to a depth of sixty or even a hundred fathoms, where they slowly spread and unfold themselves over a vast extent. Now the vessel proceeds slowly on in the manner of our trolling, and as soon as the skilled hand of the fisher observes that the rope pulls, and consequently something is fastened to the net, he pulls it slowly up, and the treasure, if any there is, is heaved on board with great care, and now comes the task of picking out the precious treasure from the meshes of the network, and to loosen them from the fragments of stone on which they are growing.
