They went on till they saw the tracks of buffalo hoofs.
"O sister dear, how thirsty I am!"
"Drink not, little brother, or you will be a buffalo calf."
They passed on and saw the tracks of bears' paws.
"Oh, I am so thirsty, sister dear."
"Drink not, little brother, or you will become a little bear."
They went on and saw the tracks of swine's trotters.
"O sister dear, I am going to drink."
"Drink not, little brother, or you will become a little pig."
They went on and on till they saw the tracks of the pads of wolves.
