Sol Finding #1146 is a boundary-numeral correction, not a census-count reconciliation.
Schoolcraft’s 1845 St. Regis discussion (printed p. 71) says: when the 54° parallel came to be drawn under the Treaty of Ghent, it cut the St. Regis settlement unequally in two. The photographed page really prints 54° — not an OCR swap.
1783 Definitive Treaty of Peace and 1814 Treaty of Ghent both specify the forty-fifth degree of north latitude. Schoolcraft’s printed numerals are reversed relative to both diplomatic texts.
Reading 54° literally would misplace the international border and the New York/Canada distinction central to his account. The correction is geographically consequential.
What it does not do. It does not identify who inverted the digits (author, copyist, typesetter). It does not reconcile the same paragraph’s 360 New York St. Regis residents with the reservation abstract’s 260 (#1140). Boundary-number ≠ census-count.
