This midnight-spout had almost grown a forgotten thing, when, some days after, lo! at the same silent hour, it was again announced: again it was descried by all; but upon making sail to overtake it, once more it disappeared as if it had never been. And so it served us night after night, till no one heeded it but to wonder at it. Mysteriously jetted into the clear moonlight, or starlight, as the case might be; disappearing again for one whole day, or two days, or three; and somehow seeming at every distinct repetition to be advancing still further and further in our van, this solitary jet seemed for ever alluring us on.
