DESCRIPTION, &c. To the President and Members of the American Antiquarian Society. Albany, 24 October, 1827. Gentlemen, Several years ago I was informed by William Smith, Esq., author of a History of Canada, and son of the historian of the Province of New York, that it appeared, from his historical researches, that the Marquis De la Galissioniere, a governor of Canada, had, at a remote period, ordered leaden plates to be buried at particular stations, asserting the exclusive right of France to all the region west of the Apalachian mountains; and that it was probable, that some of these plates might be dis- covered at some future time, and be a subject of speculation. Some time after this conversation, I received a letter from Caleb Atwater, Esq., the distinguished antiquary of the West, which announced the discovery of one of these plates. The letter is as follows, to wit : " Circleville, May 15th, 1821.

We have deposited this plate at the mouth of the river Yenangue, this 16th August, near the river Oyo (Ohio), otherwise called the Beautiful River, as a monument and memorial of the reestablishment of our power in that territory, which we claim near that river, and near all those which empty into it; and in all that country on both sides, and in the neighbourhood of the sources of those rivers, and which we have gained to our empire by a long line
