After ceding territory on several occasions new municipalities were created, Newton Township ceased to exist on 11 April 1864.
[1]: p.231 The boundaries of Newtown Township at its creation were, as follows: Therefore We humbly pray that we may be erected into a Township or Precinct as followeth, Beginning at Musconetriunk where the Quintipetite Line crosses said Musconetriunk Thence running up Musconetriunk to the great Pond to the North west Corner thereof from thence a North east point to the [New] York Line Then Northerly by York Line till they come to the foot of Pequale Mountain Thence SouthWesterly along the foot of said Mountain till it meet with the aforesaid Quintipolite Line Thence along said line to the place where it began.
[2][1]: p.56, 58 The Quintipartite Line referenced in this description is the boundary line agreed upon in the 1675 agreement to divide the proprietary colonies of East Jersey and West Jersey.
After several attempts to survey this boundary, it was accurately drawn in 1743 as the Lawrence Line.
Great Pond refers to Lake Hopatcong and Musconetriunk is the Musconetcong River.
