I take the liberty to enclose for your acceptance a copy of my Thanksgiving Discourse. The Appendix contains some documents not before published. I hope the publication of them, in the manner I have done, will not be deemed premature. I did it by the advice of some of the wisest & best informed men in this vicinity. I think it my duty, confidentially to make known to you the sources from which I obtained my information, that you may better know how to appreciate its authenticity. It will rest with you, Sir, to make what use of it you may think expedient. I wish it may be communicated to the President. Mr. J. Jackson, Supervisor, favored me with Mr. Marbois’ Letter, & the Letter p. 41 whh is from Mr. Adams.—I should not have published the latter, had it not before appeared in print in a political pamphlet printed in Phila lately. The member of Congress from whom I derived the documents contained between pages 43 & 52, is Mr. S. Higginson, who also wrote the Letters whh follow to page 56. Note E, p. 66 & G, p. 69 & H, p. 70 were furnished (at least the information they contain) by Mr. G. Cabot. The Letters under Note H, from a diplomatic character in Europe, are from Mr. K—g—. [Rufus King?] The Emigrant mentioned p. 69—was the Duke de Liancourt, whose name I see in Porcupine’s Gazette of January 11, as about to revisit this Country. The American was Mr. G. C. above mentioned. The note concerning Volney, p. 21 was furnished by Genl. K—x [General Henry Knox?] & Mr. G. C. The fact mentioned p. 68 relative to Paine’s Age of Reason, 15,000 copies of which are asserted to have been poured into this Country at one time from France, rests chiefly on the authority of a well written piece published last summer in Porcupine’s Gazette. I wish, Sir, if you are knowing to the fact, or can ascertain the truth, you would do me the favor to furnish me with the evidence. I know not that it will be controverted, but should it be it is well to have it in my power to substantiate it. I feel prepared to substantiate all other of my assertions. I am persuaded, Sir, you will properly appreciate my motives in making the above communication, as also in publishing the Sermon & Appendix. I live among a people many of whom err in Sentiment & Conduct through their want of information. It was especially for their benefit that the Appendix was compiled. With great and very sincere respect, I am, Sir, your most Obd. Servt, JED^H MORSE.” _Pickering Papers_, vol. xxiv, 29.
