First. The channel of the Delaware river, from  a  line  drawn  across
  said  channel,  from a granite monument erected upon the eastern bank of
  said river in the year eighteen hundred and  eighty-two,  by  the  joint
  boundary commission of the states of New Jersey and New York to mark the
  western extremity of the boundary line between said states of New Jersey
  and  New  York,  in a westerly prolongation of said boundary line up and
  along said channel of said Delaware river as it winds and turns,  for  a
  distance  of  eighty-five  miles  or  thereabouts,  to a line drawn east
  across said river from a granite monument erected upon the west bank  of
  said  river  in  the  year  eighteen  hundred  and eighty-four, by H. W.
  Clarke and C. M. Gere, to mark the eastern extremity of the  first  line
  hereinafter  described,  shall  continue to be a part of the boundary or
  partition line between the said two states; provided, however, that  the
  limit  of  territory  between the said two states shall be the center of
  the said main channel, and provided further, that each state shall enjoy
  and exercise a concurrent jurisdiction within and upon the water of said
  main channel between the lines of low  water  at  either  bank  thereof,
  between the limits hereinbefore mentioned.
Second.  The  line  extending  from the Delaware river aforesaid, at a
  point upon said river fixed and marked with monuments (which have  since
  disappeared),  by  David Rittenhouse and Samuel Holland, in the month of
  November, in the year seventeen hundred and seventy-four, west,  as  the
  same  was  surveyed  and  marked  with  monuments  in the year seventeen
  hundred and eighty-six, as far as  the  ninetieth  milestone,  by  James
  Clinton  and  Simeon  De Witt, commissioners on the part of the state of
  New York, duly appointed for that purpose by the governor of said state,
  in pursuance of an act of the legislature of said  state,  entitled  'An
  act for running out and marking the jurisdiction line between this state
  and  the  commonwealth of Pennsylvania,' passed seventh March, seventeen
  hundred and eighty-five, and David Rittenhouse, Andrew Porter and Andrew
  Ellicott, commissioners on the part of the commonwealth of Pennsylvania,
  duly appointed for that purpose by the supreme executive council of said
  commonwealth in pursuance of an act of  the  general  assembly  of  said
  commonwealth,  entitled,  'An  act  to  authorize and enable the supreme
  executive  council  to  appoint   commissioners   to   join   with   the
  commissioners appointed, or to be appointed, on the part of the state of
  New  York,  to  ascertain  the  northern boundary of this state from the
  river Delaware westward to the northwest corner of Pennsylvania,' passed
  thirty-first March, seventeen hundred and eighty-five, and from the said
  ninetieth milestone west, as the  same  was  surveyed  and  marked  with
  monuments  and  posts  in  seventeen hundred and eighty-seven by Abraham
  Hardenbergh and William W. Morris, commissioners on the part of the said
  state of New York, duly appointed in the place of  Simeon  De  Witt  and

  eighty-seven,  and  Andrew  Ellicott  and   Andrew   Porter   aforesaid,
  commissioners  on  the  part of the commonwealth of Pennsylvania, to the
  point where said line is intersected by the line of cession or  meridian

  boundary  hereinafter  described, which said line so surveyed and marked
  in the years seventeen hundred and eighty-six and seventeen hundred  and
  eighty-seven  has since been acknowledged and recognized by the said two
  states  as  a  part  of  the  limit  of  their  respective territory and
  jurisdiction, shall notwithstanding any want of conformity to the verbal
  description as written in the charter of the province  of  Pennsylvania,
  granted  to  William Penn in the year sixteen hundred and eighty-two, or
  as recited by the commissioners aforesaid, continue to be  the  boundary
  or  partition  line between the two said states, from the Delaware river
  aforesaid, to the said point of  intersection  with  the  said  line  of
  cession;  provided  that wherever upon said line the locations of any of
  the monuments, or posts, erected by the said commissioners in  seventeen
  hundred and eighty-six and seventeen hundred eighty-seven have been lost
  and  cannot otherwise be definitely fixed, then and in that case, and in
  every case where it is required to establish intervening points in  said
  line, a straight line drawn between the nearest adjacent monuments whose
  localities  are ascertained shall be understood to be, and shall be, the
  true boundary line.
Third. The line of cession, described as a meridian line,  drawn  from
  the  forty-fifth  degree  of  north  latitude,  south  through  the most
  westerly bent or inclination of Lake Ontario, in the deed of cession  to
  the United States of certain territory claimed by the state of New York,
  lying  west  of  said  line, executed first March, seventeen hundred and
  eighty-one, by  James  Duane,  William  Floyd  and  Alexander  McDougal,

  'An  act  to  facilitate the completion of the articles of confederation
  and perpetual union among the United States of America,' passed February
  nineteenth, seventeen hundred  and  eighty,  which  said  territory  was
  afterward  conveyed by the United States aforesaid to, and became a part
  of  the  territory  and  jurisdiction  of  the  said   commonwealth   of
  Pennsylvania,  as  the  said line was surveyed and marked with posts and
  monuments of stone in the year seventeen hundred and ninety,  by  Andrew
  Ellicott,  who  was  duly appointed for that purpose by the president of
  the United States, in pursuance of  a  resolution  of  congress,  passed
  nineteenth  August,  seventeen hundred and eighty-nine, which said line,
  and its prolongation due north into the waters of  Lake  Erie  until  it
  intersects  the  northern  boundary of the United States aforesaid, have
  since been acknowledged and recognized by the said two states, as a part
  of the limit of  their  respective  territory  and  jurisdiction  shall,
  notwithstanding   any   possible   want  of  conformity  to  the  verbal
  description thereof, as contained in said deed of cession,  continue  to
  be the boundary or partition line between the two said states, so far as
  said  line  so surveyed and marked in seventeen hundred and ninety shall
  extend.
