US Presidency
1848

Texas, lying contiguous to the western boundary of Louisiana, embracing within its limits a part of the navigable tributary waters of the Mississippi and an extensive seacoast, could not long have remained in the hands of a foreign power without endangering the peace of our southwestern frontier. Her products in the vicinity of the tributaries of the Mississippi must have sought a market through these streams, running into and through our territory, and the danger of irritation and collision of interests between Texas as a foreign state and ourselves would have been imminent, while the embarrassments in the commercial intercourse between them must have been constant and unavoidable. Had Texas fallen into the hands or under the influence and control of a strong maritime or military foreign power, as she might have done, these dangers would have been still greater. They have been avoided by her voluntary and peaceful annexation to the United States. Texas, from her position, was a natural and almost indispensable part of our territories.
