screw left her to drift at the mercy of the currents. I supposed that the crew was occupied with interior repairs, rendered necessary by the violence of the mechanical movements of the machine.
My companions and I then witnessed a curious spectacle. The hatches of the saloon were open, and as the beacon-light of the Nautilus was not in action, a dim obscurity reigned in the midst of the waters. I observed the state of the sea under these conditions, and the largest fish appeared to me no more than scarcely defined shadows, when the Nautilus found herself suddenly transported into full light. I thought at first that the beacon had been lighted, and was casting its electric radiance into the liquid mass. I was mistaken, and after a rapid survey perceived my error.
The Nautilus floated in the midst of a phosphorescent bed, which, in this obscurity, became quite dazzling. It was produced by myriads of luminous animalculæ, whose brilliancy was increased as they glided over the metallic hull of the vessel. I was surprised by lightning in the midst of these luminous sheets, as though they had been rivulets of lead melted in an ardent furnace, or metallic masses brought to a white heat, so that, by force of contrast, certain portions of light appeared to cast a shade in the midst of the general ignition, from which all shade seemed banished. No; this was not the calm irradiation of our ordinary lightning. There was unusual life and vigor; this was truly living light!
In reality, it was an infinite agglomeration of colored infusoria, of veritable globules of diaphanous jelly, provided with a thread-like tentacle. As many as twenty-five thousand have been counted in less than two cubic half-inches of water. Their light was increased by the glimmering peculiar to the medusæ, starfish, aurelia, and other phosphorescent zoöphytes, impregnated by the grease of the organic matter decomposed by the sea, and, perhaps, the mucus secreted by the fish.
During several hours the Nautilus floated in these brilliant waves, and our admiration increased as we watched the marine monsters disporting themselves like salamanders. I saw there, in the midst of this fire that burns not, the swift and elegant porpoise (the indefatigable clown of the ocean), and some sword-fish ten feet long, those prophetic heralds of the hurricane, whose formidable sword
