A CERTAIN rich man bought in the market a Goose and a Swan. He fed the
one for his table and kept the other for the sake of its song. When the
time came for killing the Goose, the cook went to get him at night,
when it was dark, and he was not able to distinguish one bird from the
other. By mistake he caught the Swan instead of the Goose. The Swan,
threatened with death, burst forth into song and thus made himself
known by his voice, and preserved his life by his melody.
