Documentary History of the State of New York, Vol. IV
One Ranesslaer claims twenty four miles square on the East, & twenty four miles square on the West side of Hudsons River, a Tract of Land sufficient for thirty two Townships of six Miles Square each & comprehends more good Land, than any other subject in His Majesty's Dominions, but Renesslaer has not thought fit to contend with the Massachusetts for the four miles, presuming it will be His Majesty's Pleasure, that a North & South Line should divide both the Massachusets and New Hampshire from the Government of New York. I have extended the Western Boundary of New Hampshire as far West as the Massachusets have done theirs, that is, within twenty Miles of Hudsons River. It will also be for the Peace and Benefit of both Governments, if it should be His Majesty's Pleasure to determine the Northern as well as the Eastern Boundary of New York, that it may be ascertained how many Miles North of the City of Albany that Government extends, as it will in its Northern & Eastern Boundary interfere with the Western Boundary of New Hampshire which will keep both Governments from extending their Settlements beyond their own Boundaries, & be easily submitted to before the Inhabitants have improved the Lands in virtue of Grants from either Government.
It will be necessary to inform your Lordships that the Government of New York was founded on a Grant made by the Crown to the Duke of York, & that it was to commence at the Sea, and run sixty miles North into the Country, which Line will cross Hudson's River about twenty Miles South of the city of Albany.
