The Documentary History of the State of New York, Vol. I — Passage 91
[E.B. O'Callaghan (1849)] Latitude 45 the Proclamation of His present Majesty of the 7lh of October 1763, leaving the juris-diction Southward of that Latitude as it stood before, tho' it prohibits for the present the further Extention of the Grants and Settlements into the Country thereby reserved to the Indians, to avoid givin0-Umbrage to that People who complained they were too much straitned in their hunting grounds. It is uncertain to this Day to what Extent the Five Nations carried their claim to the Westward & Northward but there is no doubt it went to the North beyond the 45 Degree of Latitude and Westward to Lake Huron, their Beaver Hunting Country being bounded to the West by that Lake, which Country the Five Nations by Treaty with the Governor of this Province at Albany in 1701 surrendered to the Crown to be protected and defended for them — Mitchel in his Map extends their claim much further Westward and he is supported in this opinion by Maps and other Authorities very Ancient and Respectable. The above Treaty of 1701 is to be found among the Records of Indian Transactions but it is recited and the Surrender made thereby confirmed in a Deed dated the 14th September 1726 by which the Seneca, Cayouga and Onondaga Nations also surrender^ their Habitations to King George the first a Copy whereof is inserted in the article of the Appendix, Number 1.
