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 swordfish ten feet long, those prophetic heralds of the hurricane whose formidable sword would now and then strike the glass of the saloon. Then appeared the smaller fish, the balista, the leaping mackerel, wolf-thorn-tails, and a hundred others which striped the luminous atmosphere as they swam. This dazzling spectacle was enchanting! Perhaps some atmospheric condition increased the intensity of this phenomenon. Perhaps some storm agitated the surface of the waves. But at this depth of some yards, the Nautilus was unmoved by its fury and reposed peacefully in still water. So we progressed, incessantly charmed by some new marvel. The days passed rapidly away, and I took no account of them. Ned, according to habit, tried to vary the diet on board. Like snails, we were fixed to our shells, and I declare it is easy to lead a snail’s life. Thus this life seemed easy and natural, and we thought no longer of the life we led on land; but something happened to recall us to the strangeness of our situation. On the 18th of January, the Nautilus was in 105° long. and 15° S. lat. The weather was threatening, the sea rough and rolling. There was a strong east wind. The barometer, which had been going down for some days, foreboded a coming storm.
