A Hare once said to a Harrier:
"Why do you bark when you run after us? You would catch us easier, if
you ran after us in silence. With your bark you only drive us against
the hunter: he hears where we are running; and he rushes out with his
gun and kills us, and does not give you anything."
The Harrier said:
"That is not the reason why I bark. I bark because, when I scent your
odour, I am angry, and happy because I am about to catch you; I do not
know why, but I cannot keep from barking."
