Documentary History of the State of New York, Vol. IV
Wuerras His Honor Cadwallader Colden Esqt Lieutenant Governor and commander in chief of His Majestys Province of New York hath lately issued a Proclamation of a very extraordinary nature, Seting forth that King Charles the Second, on the 12th day of March 1663|4 and the 29th June 1674, did by his several Letters patent of those dates, grant in fee to his Brother the Duke of York among other Things all the Land from the west Side of Connecticut River to the East Side of Delaware Bay and therein also sets forth, or describes the Bounds of New Hampshire, in which description there is a very material mistake, besides there is omitted the fact, on which the description of New Hampshire depended, vizt His Majesty's determination of the northern, and western Boundarys of the province of the Massachusets Bay in 1739 & nothing can be more evident, than, that New Hampshire may legally extend' her western Boundary as far as the Massachusets claim reaches ; and She claims no more, but New York pretends to claim even to the Banks of Connecticut River although She never laid out and Settled one town in that part of His Majesty's Lands Since she existed as Government. When New York Government extends her Eastern Boundary, to the Banks of Connecticut River between New York and the Colony of Connecticut, & to the Banks of said River, between New York & the province of the Massachusets Bay, it wou'd have been full early for New York to declare that the Government of New Hampshire was fully apprized of the Right of New York under the before recited Letters pattent to the Duke of York.
