Baltimore 17th. June 1807—
From the hostility manifested towards our Government & the Present Administration, by those who take to themselves the false name of Federalist, Particularly in the case of Burrs Trial, I deem it a duty that every faithful Native American owes his Country, and those who are Placed in the Executive Departments thereof, to make any communications he may think will Promote the Publick Good—Mr. Philip Graybell of this Place, a very worthy old revolutionary Officer & an undoubted friend to our Present Government & your Administration of it, told me last Evening, that Mr. Luther Martin mentioned to him as early as last Summer, that Burr was then concerting measures to separate the Union & that he did not doubt but he would effect it,—To my mind this is strong & conclusive evidence that L. Martin was either associated with him in his diabolical intentions, or at least he knew it was friendly to his scheme—
I beg leave to request that, should you think fit to have Mr. Graybell’s evidence at Richmond, that my name will not be used unless necessary, for I have not before this mentiond this circumstance to any other, nor do I intend it but for your use.
I am Dr Sir your mo. Devoted Friend
Of the House of John & Wm Gordon
P.S. The Secretary is well acquainted with Mr. Graybell & though he cannot be well acq with me, yet I Presume he is Not a stranger to my Political Creed—
