And indeed there was some excuse for the negro's extraordinary behaviour; for, intense as was the darkness that enveloped us, the water was faintly phosphorescent, and we were thus enabled to discern indistinctly that, less than a hundred yards distant from us, a huge creature, which, to our excited imaginations, appeared to be between two and three hundred feet long, had risen to the surface and was now slowly swimming in a direction that would carry it across the bows of the longboat at a distance of some fifty feet.  I frankly confess that for a moment I felt petrified with horror, for the creature was streaming with faintly luminous phosphorescence, and thus, despite the darkness, it was possible to see that it was certainly not a whale, or any other known denizen of the deep, for it had a head shaped somewhat like that of an alligator--but considerably larger than that of any alligator I had ever seen--attached to a very long and somewhat slender neck, which it carried stretched straight out before it at an angle of some thirty degrees with the surface of the water, and which it continually twisted this way and that, as though peering about in search of something. Suddenly it paused, lifted its head high, and looked straight toward the boats, and at the same moment a whiff of air came toward us heavily charged with a most disgusting and nauseating odour, about equally suggestive of musk and the charnel-house.  Its eyes, distinctly luminous, and apparently about two feet apart, were directed straight toward the longboat, and the next instant it began to move toward us, again stretching out its neck.
