A CORRESPONDENT, who is a native of the South, thinks that the recurrence the other day to the effects of "Uncle Tom's Cabin" was interesting enough as a narrative, but wishes to express the opinion that it would be better if the book and the play were both to be "cast into oblivion as abominable falsehoods" and that they are still producing mischievous, if not dangerous, impressions. Oddly enough another reader, who is in sympathy with the negro's point of view on questions pertaining to the races, is inclined to think the same way, believing that it would be better not to have the negro put on the stage in such plays because of the "antagonistic feelings" they awaken.
