英语寓言故事-The Partridge and the Fowler

A FOWLER caught a Partridge and was about to kill it.  The
Partridge earnestly begged him to spare his life, saying, "Pray,
master, permit me to live and I will entice many Partridges to
you in recompense for your mercy to me."  The Fowler replied, "I
shall now with less scruple take your life, because you are
willing to save it at the cost of betraying your friends and
relations."
