E. Carpenter. Music by Stephen Glover._ O’er the waves we float, we float, Fairies two, in our fairy boat, Fanned by the breezes, rocked by the tide, In our nautilus barque we glide, we glide. When the strong cordage snaps in the gale, Safe o’er the surges we sail, we sail; In the bright calm we rest on the deep, And, lulled by the zephyrs, we sleep, we sleep. Cast by the winds from shore to shore, A moment you view us, and then no more. The nautilus shell, by human eyes, Is seen on the waters, that sink and rise, Over the billows away and away; Ours is the freedom that knows no decay. Braving the tempest, and stemming the tide, In safety forever, we glide, we glide. “As for Millie Chrissy, the two-headed girl, she is a perfect little gem or gems, or a gem and a half, we don’t know which. She sings with one or two voices very sweetly, and in dancing we never saw any one more graceful. We expected to see a monstrosity, but were agreeably disappointed; on the contrary, we found her pleasing in appearance, agreeable in her manners, and endowed with good conversational powers. Great care and attention must have been bestowed upon her education.”--_New York Times._ “Take the children and go to Odd Fellow’s Hall, and see the wonderful two-headed girl combination while you have an opportunity, and you will thank us for the advice.”--_Washington Republican._
