Note 5 — INTRODUCTION
Reading edition
Our treaty with Spain, made in 1819, adjusted the boundary as far as the Pacific Ocean, between the latter's possessions in North America and those of the United States; see Gregg's Commerce of the Prairies, in our volume xix, p. 217, note 52. By this convention the United States considered itself the heir of all Spanish claims north of the international boundary line (42°).
Our treaty with Mexico, in 1828, ratified the boundary as defined by the Spanish treaty of 1819.
By our convention with Russia in 1824, the two countries agreed to make no settlements north or south, respectively, of the line 54° 40´. This by no means established the United States claim as far as the line specified.—Ed.
