MEPHISTOPHELES
Gray is, young friend, all theory:
And green of life the golden tree.
STUDENT
I swear it seemeth like a dream to me.
May I some future time repeat my visit,
To hear on what your wisdom grounds your views?
MEPHISTOPHELES
Command my humble service when you choose.
STUDENT
Ere I retire, one boon I must solicit:
Here is my album; do not, Sir, deny
This token of your favor!
MEPHISTOPHELES
Willingly!
