Twain takes the piss out of Cooper in superb style.
Look at this opening line:
“It seems to me that it was far from right for the Professor of English Literature at Yale, the Professor of English Literature in Columbia, and Wilkie Collins to deliver opinions on Cooper’s literature without having read some of it. It would have been much more decorous to keep silent and let persons talk who have read Cooper.”
I believe the honourable gentleman just got told.
P.S. The first two of the Leatherstocking tales are still very dear to my heart.
