`` O , it is my sister 's ! '' answered Quicksilver . `` She is coming along with us , as I told you she would . We could do nothing without the help of my sister . You have no idea how wise she is . She has such eyes , too ! Why , she can see you , at this moment , just as distinctly as if you were not invisible ; and I 'll venture to say , she will be the first to discover the Gorgons . '' By this time , in their swift voyage through the air , they had come within sight of the great ocean , and were soon flying over it . Far beneath them , the waves tossed themselves tumultuously in mid-sea , or rolled a white surf-line upon the long beaches , or foamed against the rocky cliffs , with a roar that was thunderous , in the lower world ; although it became a gentle murmur , like the voice of a baby half asleep , before it reached the ears of Perseus . Just then a voice spoke in the air close by him . It seemed to be a woman 's voice , and was melodious , though not exactly what might be called sweet , but grave and mild . `` Perseus , '' said the voice , `` there are the Gorgons . '' `` Where ? '' exclaimed Perseus . `` I can not see them . '' `` On the shore of that island beneath you , '' replied the voice . `` A pebble , dropped from your hand , would strike in the midst of them . '' `` I told you she would be the first to discover them , '' said Quicksilver to Perseus . `` And there they are ! '' Straight downward , two or three thousand feet below him , Perseus perceived a small island , with the sea breaking into white foam all around its rocky shore , except on one side , where there was a beach of snowy sand .
He descended towards it , and , looking earnestly at a cluster or heap of brightness , at the foot XXXXX a precipice of black rocks , behold , there were the terrible Gorgons !
