At a time when the animals spoke, a Wagtail laid her eggs on the ground. The little ones grew up. A Jackal and a Fox came to them. The Jackal said to the Fox:  
"Swear to me that the Wagtail owes me a pound of butter."
 
The Fox swore to it. The Bird began to weep. A Greyhound came to her and asked her what was the matter. She answered him:
 
"The Fox has calumniated me."
 
"Well," said the Hound, "put me in this sack of skin."
