Answer:
Step-by-step explanation:
The treaty set the western boundary of Louisiana along the Sabine and Red rivers which separate Texas and Louisiana, then north along the 100th meridian to the Arkansas River which it followed westward to its source in the Rockies, then north to the 42nd north latitude, and on a line then west to the Pacific Ocean. An undated subsequent edition of Missouri Territory Formerly Louisiana by Carey and Lewis, probably published after 1818, has been amended by hand in watercolor to record some of the treaty adjustments.
