The hen bird was about to lay, and she asked her mate whether he could find her some place convenient for laying eggs. He asked, whether that was not a very good place for the purpose. She answered that it was not, for it was continually overflowed by the tide. Then he asked emotionally, whether he had become so feeble that the eggs laid in his house could be carried away by the sea. The hen bird laughed and said that there were some considerable defferences between him and the sea.
