Sunday Morning Puzzle #65 --A Difficult Cryptogram

Below is a simple cryptogram made more difficult by the addition of 37 extra letters. These extra letters separate every two words which, otherwise, run together. As a bonus the extra letters spell out the source of the text. There is one hyphenated word, but all other punctuation has fled. I think I know how to rate this puzzle!
