I have a collection of interesting papers (found among my father’s papers at Kinderhook) relating chiefly to Indian affairs during the first half of the last century in the colony of New-York. These I am arranging, at my leisure, for the purpose of presentation to the N. Y. H. Society. I hope also to be able to send some papers of my father’s which will advance the object of the society in rescuing the Indian names on the east banks of the Hudson from oblivion, and which last I had intended to forward to the Society through you. But I must take my time to effect those objects. Excuse the haste with which this letter is written, as I have only this moment received your letter, and I do not wish to lose a mail. Respectfully yours. _Manlius, Nov. 22nd, 1845._ DEAR SIR: I forwarded to Mr. Gibbs, the librarian, a few days ago a volume containing various MSS. selected from my father’s papers, relating chiefly to our aboriginal history, and about which I wrote you some time ago. You will find among them the journal of Conrad Weiser, Indian interpreter, giving an account of a visit to the Six Nations in 1745, at which time he accompanied the Senecas to Oswego, on their way to pay a visit to the Governor of Canada. You will also find among the papers, the original minutes of the Grand Council at Albany, in 1745, at which were present commissioners from Massachusetts, Connecticut, Pennsylvania, and New-York, with Governors from several of those States and the Sachems of the Six Nations. I think you will be interested in some of the papers. When I visit Kinderhook again, I hope to be able to make some additions to the contribution I have made to the Society. Many of the old papers relating to land trials, contain matter throwing light upon Indian names of objects and places. I, however, despair of ever seeing anything like a completeness of that description. Respectfully yours, H. C. VAN SCHAACK. (P.) Letter from L. T. Morgan, Esq., to H. R. Schoolcraft. _Rochester, October 7, 1845._ SIR—You have doubtless seen a notice of the great council of the Six Nations, recently held at Tonawanda. We call it great, because we never saw any thing of the kind before, and perhaps never will again. Three of us started in season, and spent the whole of last week in attendance, and were also joined by Mr. Hurd, a delegate from Cayuga. We were there before the council opened, and left after the fire was raked up. Our budget of information is large, and overthrows some of our past knowledge, and on the whole, enlarges our ideas of the vastness and complexity of this Indian fabric. We are a great way from the bottom yet; we may never reach it, but what we do bring up to the surface, remunerates richly for the search.
