I'm sure I would be able to understand the vivid descriptions and symbolism in this book much better, if Hawthorne were not writing in some sort of moon man language. I don't know about the production of narcotics in the 1800's, but I honestly think that Hawthorne wasn't on a natural high if you know what I'm saying.

Ex Output:
Negative
