There was once upon a time an old goat who had seven little kids, and

loved them with all the love of a mother for her children. One day
she wanted to go into the forest and fetch some food. So she called
all seven to her and said, dear children, I have to go into the
forest, be on your guard against the wolf, if he comes in, he will
devour you all - skin, hair, and everything.  The wretch often
disguises himself, but you will know him at once by his rough voice
and his black feet.  The kids said, dear mother, we will take good
care of ourselves, you may go away without any anxiety.  Then the old
one bleated, and went on her way with an easy mind.

It was not long before some one knocked at the house-door and called,
open the door, dear children, your mother is here, and has brought
something back with her for each of you.  But the little kids knew
that it was the wolf, by the rough voice.  We will not open the door,
cried they, you are not our mother.  She has a soft, pleasant voice,
but your voice is rough, you are the wolf.  Then the wolf went away
to a shopkeeper and bought himself a great lump of chalk, ate this
and made his voice soft with it. The he came back, knocked at the
door of the house, and called, open the door, dear children, your
mother is here and has brought something back with her for each of
you.  But the wolf had laid his black paws against the window, and
the children saw them and cried, we will not open the door, our
mother has not black feet like you, you are the wolf.  Then the wolf
ran to a baker and said, I have hurt my feet, rub some dough over
them for me.  And when the baker had rubbed his feet over, he ran to
the miller and said, strew some white meal over my feet for me.  The
miller thought to himself, the wolf wants to deceive someone, and
refused, but the wolf said, if you will not do it, I will devour you.
Then the miller was afraid, and made his paws white for him. Truly,
this the way of mankind.
