or 3 miles south of the southernmost bend of the Charles River, whichever was farther south. The northern border was to be 3 miles north of the northernmost bend of the Merrimack River. Between these lines of latitude the grant extended from the Atlantic to the Pacific. In 1629 the rivers had not been fully explored and the actual borders of the colony were uncertain. It turned out that the southernmost bend of the Charles is south of the southern curve of Massachusetts Bay. The line of latitude three miles south of the river's southernmost bend, approximately 42°2′ north, forms the basis of the southern border of Massachusetts to the present day. The Merrimack River turned out to originate farther north than expected, flowing south for most of its course and only turning eastward in its last several miles. Thus the 1629 grant gave the colony most of what is today New Hampshire and all of the original 1629 grant that formed the basis of colonial New Hampshire, but it took many decades before this was fully understood.
A new charter was granted to the

. New Hampshire appealed to
King George II, who in 1740 decreed the boundary to run along a curved line three miles from the river between the ocean and a point three miles north of
Pawtucket Falls (Lowell), where the river begins to turn north. From there a line was to be drawn due west to meet the
western boundary of Massachusetts (fixed in 1773 with the

). The line actually runs slightly northwest to southeast, so it follows no line of latitude. This gave New Hampshire even more than it had claimed, as Pawtucket Falls was south of the mouth of the Merrimack. At this time, the present northern boundary of Massachusetts was established.
The location where these two surveyed lines met (the straight westward line and the curved line following the Merrimack River) was marked by a pine tree called the "Old Boundary Pine". The tree was
