The Bad Child's Book of Beasts

I call you bad, my little child, Upon the title page, Because a manner rude and wild Is common at your age. The Moral of this priceless work (If rightly understood) Will make you—from a little Turk— Unnaturally good. Do not as evil children do, Who on the slightest grounds Will imitate Kangaroo the Kangaroo, With wild unmeaning bounds. Do not as children badly bred, Who eat like little Hogs, And when they have to go to bed Will whine like Puppy Dogs.
