Vowels.
My first a baby does when you pinch it;
My second a lady says when she doesn’t mean it;
My third exists and no one e’er has seen it;
And my whole contains the world’s best half within it.
Cri-no-line.
Formed long ago, yet made to-day,
I’m most employed while others sleep;
What none would like to give away,
Yet no one likes to keep.
