Why should’st thou waste thy flickering flame in vain?

Pray be so good as light us up the hill!

Will-o-the-Wisp.

Out of respect to you, I will restrain,

If possible, my ever-shifting will;

But all our natural genius, and our skill

Is zigzag; straight lines go against the grain.

Mephistopheles.

Ha! ha! hast learned from men how to declaim?

March on, I tell thee, in the Devil’s name!
