Week after next we propose to commence in the Era, the publication of a new story by Mrs. H. B. Stowe, the title of which will be, "UNCLE TOM'S CABIN, OR THE MAN THAT WAS A THING." It will probably be of the length of the Tale by Mrs. Southworth, entitled Retribution.

  Mrs. Stowe is one of the most gifted and popular of American writers. We announce her story in advance, that none of our subscribers, may lose the beginning of it, and that those who desire to read the production as it may appear in successive numbers of the Era, may send us their names in season.
