Think Before You Speak; Or, The Three Wishes is a children's tale by Catherine Ann Turner Dorset. Dorset was a British writer of rhymes for children. Excerpt:

"Now, by the honour of a Spright

Who in good actions takes delight,

By Mab, the sovereign of fays,

Who sports beneath the moon's pale rays,

I grant to you and your good dame

The first Three Wishes that you name!

Think what will best your state amend,

And claim it from your grateful friend!

17Together you had best advise,

And as you are humane, be wise!

For should you foolishly decide,

By your own choice you must abide;

Nor further does my power extend,

Howe'er dispos'd to be your friend."
