280. The Florida Treaty, 1819. -While this contest was going on, the United States bought of Spain a large tract of land admirably suited to negro slavery. This was Florida. It belonged to Spain and was a refuge for all sorts of people: runaway negroes, fugitive Indians, smugglers, and criminals of all kinds. Once in Florida, fugitives generally were safe. But they were not always safe. For instance, in 1818 General Jackson chased some fleeing Indians over the boundary. They sought refuge in a Spanish fort, and Jackson was obliged to take the fort as well as the Indians. This exploit made the Spaniards more willing to sell Florida. The price was five million dollars. But when it came to giving up the province, the Spaniards found great difficulty in keeping their promises. The treaty was made in 1819, but it was not until 1821 that Jackson, as governor of Florida, took possession of the new territory. Even then the Spanish governor refused to hand over the record books, and Jackson had to shut him up in prison until he became more reasonable.
