For the National Era.

MRS. H.B. STOWE.

  Will this lady allow an humble individual to throw out a suggestion? Something seems wanting in the shape of an Appendix, a Sequel, or a Companion to Uncle Tom's Cabin, having for its object the depicting of the evil effects of slavery on the whites, in their varied relations of masters, overseers, parents and children, husbands and wives, church-ministers and members, the rich and the poor, the young and the old, manufacturers and workmen, &c. A voluminous subject, truly! but one which Mrs. S. can do justice to, if any one can.

  True, Uncle Tom's Cabin gives some exhibitions of this kind, and the public prints occasionally reveal a little, but they are so isolated and far between, or so surrounded with other matter, that they seldom have more than a transient effect. Were they embodied in a continuous narrative, wrought up in the style of Mrs. Stowe's popular work, they would tell with hundred-fold effect. The general belief that slavery is as fraught with evils to the whites as to the blacks, reduced into a tangible, practical bearing, would be of incalculable value to the interests of humanity, and seems a desideratum. None can so well supply this vacuum as the authoress of Uncle Tom; and lest she should hesitate for want of materials, I would suggest to your readers to forward to Mrs. Stowe at once (post paid) such authentic facts, anecdotes, narratives, &c., as they may possess. Never fear, friends, to trust Mrs. Stowe with your communications and your names; she will use them prudently and efficiently for Truth and Humanity.

THE "NORTHERN FARMER."

  I was truly glad to see your exposure of this masked concern. Some days before, I was asked to subscribe for it, and a late number handed me to examine. In addition to its pro-slavery character, the editor in the young men's department insisted that the masses of Europe were like the socialists of France, unfit for liberal institutions, and needed the strong arm of monarchy to keep them in order! I was assured, as a strong recommendation, that the agent was Mr. C——, a Presbyterian minister of this town. How true it is that the so-called ministers of the Gospel (!!!) are the main pillars of slavery, and the insidious enemies of popular rights. Yet there are a few noble exceptions; may God increase their number daily!

  By the bye, can't the Free Democracy issue a periodical (but not masked) in a similar cheap and popular style?—sixteen double-column centavo pages, monthly, at 25 cents a year.
