The very honorable treatment received by me from Mr. McLoughlin during the years inclusive from 1832 to 1836, during which time there were no other Americans on the Lower Columbia, except myself and parties, calls on me to state the facts. The purpose of this letter is to ask the favor of you to inform me what matter is pending, in which Mr. McLoughlin’s interests are involved, and before whom, and if you will present a memorial from me on the matters stated in Mr. Thurston’s letter as above. Respectfully and truly your ob’t servant, NATH. J. WYETH. WASHINGTON, Dec. 28, 1850. DEAR SIR—I took the earliest opportunity to enquire of Mr. Thurston what there was pending before Congress or the Executive, in which Mr. McLoughlin’s character or interest were concerned. He would tell me nothing, nor am I aware of anything. Respectfully your ob’t serv’t, R. C. WINTHROP. To N. J. WYETH, Esq. _John McLoughlin, Esq._: DEAR SIR—On the 19th of December, 1850, I received a letter from Sam’l R. Thurston, delegate from Oregon, of which see copy No. 1, and by same mail an Oregon newspaper containing a communication over your signature, the letter [latter], I think, addressed in your handwriting. From the tenor of Mr. Thurston’s letter, I presumed he wanted my testimony for some purpose not friendly to yourself. I answered his letter as per copy No. 2, but doubting if my testimony, except it suited his views, would be presented, and being ignorant of his intentions, I wrote the Hon. R. C. Winthrop, late Speaker of the House of Representatives, and at present a member of the Senate of the United States, as per copy, (No. 3) and received from him a reply as per copy (No. 4). Should you wish such services as I can render in this part of the United States, I shall be pleased to give them in return for the many good things you did years since, and if my testimony as regards your efficient and friendly actions towards me and the other earliest Americans who settled in Oregon, will be of use in placing you before the Oregon people in the dignified position of a benefactor, it will be cheerfully rendered. I am, with much respect, yours truly, NATH. J. WYETH.
