The year after, the fifth sister attained her fifteenth year. Her birthday happened at a different season to that of her sisters; it was winter, the sea was of a green colour, and immense icebergs were floating on its surface. These, she said, looked like pearls; they were, however, much larger than the church-towers in the land of human beings. She sat down upon one of these pearls, and let the wind play with her long hair, but then all the ships hoisted their sails in terror, and escaped as quickly as possible. In the evening the sky was covered with sails; and whilst the great mountains of ice alternately sank and rose again, and beamed with a reddish glow, flashes of lightning burst forth from the clouds, and the thunder rolled on, peal after peal. The sails of all the ships were instantly furled, and horror and affright reigned on board, but the princess sat still on the iceberg, looking unconcernedly at the blue zig-zag of the flashes. The first time that either of these sisters rose out of the sea, she was quite enchanted at the sight of so many new and beautiful objects, but the novelty was soon over, and it was not long ere their own home appeared more attractive than the upper world, for there only did they find everything agreeable. Many an evening would the five sisters rise hand in hand from the depths of the ocean. Their voices were far sweeter than any human voice, and when a storm was coming on, they would swim in front of the ships, and sing,--oh! how sweetly did they sing! describing the happiness of those who lived at the bottom of the sea, and entreating the sailors not to be afraid, but to come down to them. The mariners, however, did not understand their words; they fancied the song was only the whistling of the wind, and thus they lost the hidden glories of the sea; for if their ships were wrecked, all on board were drowned, and none but dead men ever entered the Mer-king’s palace. Whilst the sisters were swimming at evening-time, the youngest would remain motionless and alone, in her father’s palace, looking up after them. She would have wept, but mermaids cannot weep, and therefore, when they are troubled, suffer infinitely more than human beings do. ‘Oh, if I were but fifteen!’ sighed she, ‘I know that I should love the upper world and its inhabitants so much.’ At last the time she had so longed for arrived. ‘Well, now it is your turn,’ said the grandmother; ‘come here, that I may adorn you like your sisters.’ And she wound around her hair a wreath of white lilies, whose every petal was the half of a pearl, and then commanded eight large oysters to fasten themselves to the princess’s tail, in token of her high rank. ‘But that is so very uncomfortable!’ said the little princess. ‘One must not mind slight inconveniences when one wishes to look well,’ said the old lady.
