Melville Fuller,
State of Missouri v. Iowa — Opinion of the Court
“ In order that the relative positions of the actual mile points between the 40th and 60th mile points could be properly determined, and also their true relation to the theoretical points as found in accordance with the courses and distances shown in Hendershott's report, it was deemed necessary to establish a chord or base line twenty miles in length between the 40th and 60th iron monuments to which all points actually found and definitely located or shown and claimed as being upon the boundary line could be referred, and from which all points finally determined could be accurately located. ”
