COUNTERPART TO UNCLE TOM.—The New Jersey papers state that Mrs. Tamar Davis, of Allowaystown, is preparing a work for the press, designed to be the counterpart of "Uncle Tom's Cabin," but illustrative of the condition and character of the negroes in the Free States. The scene will be laid in New Jersey, where there are several villages occupied exclusively, it is said, by colored people.

  If Mrs. D. will frame her narrative in such a way as to exhibit the true results of the New Jersey or post nati method of emancipation when tried upon a considerable body of slaves, taking children away from parents and leaving them to be brought up by those who have no interest in their permanent welfare, she may do much good, and New Jersey is able to furnish ample materials for illustration.
