York Indians in council, in order to ascertain, if possible, the views of the several tribes, and especially of the Senecas, in relation to the amended treaty. He did so in the month of August last, and the minutes of the proceedings of that council are herewith submitted. Much opposition was manifested by a party of the Senecas, and from some cause or other some of the chiefs of the other tribes who had in former councils consented to the treaty appeared to be now opposed to it. Documents were presented showing that some of the Seneca chiefs had received assurances of remuneration from the proprietors of the land, provided they assented to the treaty and used their influence to obtain that of the nation, while testimony was offered on the other side to prove that many had been deterred from signing and taking part in favor of the treaty by threats of violence, which, from the late intelligence of the cruel murders committed upon the signers of the Cherokee treaty, produced a panic among the partisans of that now under consideration.

In the report of the committee of the Senate, upon the subject of this treaty, of the 28th of February last it is stated as follows:
