+\:It is an important and popular fact that things are not always what

+that he was more intelligent than dolphins because he had achieved so
+much -- the wheel, New York, wars and so on -- whilst all the dolphins
+had ever done was muck about in the water having a good time. But
+conversely, the dolphins had always believed that they were far more
+intelligent than man -- for precisely the same reasons.
+\:Curiously enough, the dolphins had long known of the impending

+alert mankind to the danger; but most of their communications were
