Unfortunately they don't give dates or a bibliographical source for the letter. I have read other documents of this kind in other books, (which I now unfortunately don't have references to), and the language and tone are typical. What comes through, to me, under the straight business language, is the greed of these people. You know, sugar was like gold to them, and "les nègres" were just a means to the end of bringing in the gold dust.
