October 21, 1803 | Letter William Dunbar to Thomas Jefferson, October 21, 1803 William Dunbar responds to Thomas Jefferson's September 21 letter regarding the Spanish presence in Florida and the Gulf Coast and the surveys conducted by the Spanish in that region. He also praises Daniel Clark's summation of the population of the Lousiana Territory and suggests a representative from that region appear before Congress, but notes that the Spanish government is unlikely to allow such a measure to take place as long as the territory is in their hands.
