Gentlemen of the Jury, let me make this more clear by a special case wholly fictitious.--Thomas Nason, a "Non-Resistant" and a Quaker, is a colored citizen of Boston, the son and once the slave of Hon. James Nason of Virginia, but now legally become a free man by self-purchase; he has the bill of sale of himself in his pocket, and so carries about him a title deed which would perhaps satisfy your Honors of his right to liberty. But his mother Lizzie (Randolph) Nason, a descendant of both Mr. Jefferson and Mr. Madison,--for Virginia, I am told, can boast of many children descended from two Presidents, perhaps from three, who "Boast the pure blood of an illustrious race, In quiet flow from Lucrece to Lucrece"-- from Saxon master to African slave,--is still the bondwoman of the Hon. James, the father of her son Thomas. From the "Plantation manners" of her master, the concubine, "foolishly dissatisfied with slavery," flies to Boston, and takes refuge with her Quaker son, who conceals his mother, and shelters her for a time. But let me suppose that his Honor Judge Curtis, while at Washington, fired with that patriotism which is not only habitual but natural and indigenous to his Honor, informs Mr. Nason of the hiding-place of his female slave, thus betraying a "mistress" to her master, no longer, alas, her "keeper." It is no injurious imputation--it is an imaginary honor I attribute to the learned and honorable Judge. Mr. Nason sends the proper agent to Boston to save the Union of States by restoring the union of master and slave. Mr. George Ticknor Curtis, fugitive slave bill commissioner, and brother to the Hon. Judge, issues his warrant for kidnapping the mother; his coadjutor and friend, Mr. Butman, attempts to seize her in her son's house. Thomas, unarmed, resists the intruder, and with a child's pop-gun drives that valiant officer out of the house, and puts the mother in a place of safety,--beneath the flag of England, or the Pope, or the Czar. Commissioner Curtis telegraphs the news to Washington,--announcing a "NEW CASE OF TREASON--more 'levying war!'" The Secretaries of State and of War write dreadful letters, breathing fire and slaughter, and President Pierce, a man of most heroic courage, alike mindful of his former actual military exploits at Chapultepec, of his delegated triumph at Greytown, and of the immortal glory of Mr. Fillmore, issues his Proclamation, calling on all good citizens, and especially on the politicians of his party, to "Save the Union" from the treason of this terrible Thomas Nason, who will blow up the Constitution with a pop-gun!
