A Wolf wanted to pick a sheep out of a flock, and stepped into the wind, so that the dust of the flock might blow on him.
The Sheep Dog saw him, and said:
"There is no sense, Wolf, in your walking in the dust: it will make your eyes ache."
But the Wolf said:
"The trouble is, Doggy, that my eyes have been aching for quite awhile, and I have been told that the dust from a flock of sheep will cure the eyes."
