Then for the hardness of their hearts, and for the softness of their heads, I taught them Magick.

But... alas!

Teach us Your real secret, Master! how to become invisible, how to acquire love, and oh! beyond all, how to make gold.

     The term "gold bricks" is borrowed from American finance.
     The chapter is a setting of an old story.
A man advertises that he could tell anyone how to make four hundred a year certain, and would do so on receipt of a shilling. To every sender he dispatched a post-card with these words: "Do as I do."
     The word "sucker" is borrowed from American finance.
     The moral of the chapter is, that it is no good trying to teach people who need to be taught.
