Abraham Lincoln to Zachary Taylor, 15 March 18501
His Excellency the President &c.[etc.]Dear Sir:
I understand some one of our Ohio friends will probably be appointed Minister to Brazil; and if so, I hope Hon: Robert C. Schenck may be the man– In expressing a preference for Mr Schenck over others of his own State, I do not mean to say he is less worthy than any out of his state; but were I to not limit myself as I do, I should probably come in collision with some recommendation of my own, formerly made; or, perhaps with the interests of some friend of my own state2
Your Obt Servt[Obedient Servant]A. Lincoln

2Robert C. Schenck received the appointment and was minister to Brazil from 1851 to October 1853. Later in 1853, William Trousdale of North Carolina replaced Schenck as minister to Brazil.
Roy P. Basler, editor of The Collected Works of Abraham Lincoln, asserts, without attribution, that Schenck was “also accredited to Uruguay, Paraguay, and the Argentine, 1851-1853,” but the editors found no evidence to support this.
