The Crab and the Fox

A Crab once left the sea-shore and went and settled in a meadow some way inland, which looked very nice and green and seemed likely to be a good place to feed in. But a hungry Fox came along and spied the Crab and caught him. Just as he was going to be eaten up, the Crab said, "This is just what I deserve; for I had no business to leave my natural home by the sea and settle here as though I belonged to the land."
