Settlement at Niagara in 1719, which gave rise to that treaty of 1726, whereby they put tiieir Country and Hunting Lands under the Protection of the Crown of England -- Their Difficulties, when the Commissioners on the Part of Pennsylvania proposed to purchase part of this Country at Albany, and their Declaration to Sr Wm Johnson, that, notwithstanding their purchase, they would not part with it, are Circunsstanees which clearly mark out what should be the Conduct and Politicks of the English with regard to them viz. to leave them in Possession of their Country according to the Description in the Deed of 1726, and to undertake the Guarantee of it to them, protecting them and their Hunting Lands in such manner as to command both it and them, and Yet most religiously to preserve the Use to them.
Upon the whole therefore We are humbly of Opinion, that at any time, but more especially at present, when We ought cautiously to avoid giving any the least Cause of Jealousy or Distrust to the Indians, and religiously to observe Our Engagements with them, it would not be advisable to attempt the making any Settlement Upon the Lands, which by the Deed of 1726 are given by them to Your Majesty, to be protected for their Use. The Regard, which the Proprietarys of Pennsylvania ha\e at all times shewn for Your Majesty's Interest and the Publick Service, leaves Us no room to doubt of their Acquiescence in this Opinion, And We have reason to hope that their laudable design of promoting the Good of that Service by their generous Proposal will not be defeated by it, as We Observe upon an Examination of the best Geographical Description and Dilineation of this Country, that there is within the Province of Pennsylvania a space of Land between the Mountains and the Limits of the Lands described in the Deed of 1726, more than sufficient for this or any larger Settlement which may be proposed.
