During this period few books were published on Florida and none whatever in the land of the regainers of the territory. The first traveller who has left an account of his visit thither is Johann David Schöpf,[85] a German physician who had come to America in 1777, attached to one of the Hessian regiments in the British service. At the close of the war he spent two years (1783-4) in travelling over the United States previous to returning home, a few weeks of which, in March, 1784, he passed in St. Augustine. He did not penetrate inland, and his observations are confined to a description of the town, its harbor and inhabitants, and some notices of the botany of the vicinity--for it was to natural history and especially medical botany that Schöpf devoted most of his attention during his travels. The difficulties of Spain with the United States in regard to boundaries gave occasion for some publications in the latter country. As early as 1797, the President addressed a message to Congress “relative to the proceedings of the Commissioner for running the Boundary Line between the United States and East and West Florida,” which contains a resumé of what had been done up to that date. Andrew Ellicott, Commissioner in behalf of the United States, was employed five years in determining these and other boundaries between the possessions of our government and those of His Catholic Majesty. He published the results partially in the Transactions of the American Philosophical Society, and more fully several years afterwards in a separate volume.[86] They are merely the hasty notes of a surveyor, thrown together in the form of a diary, without attempt at digestion or connection; but he was an acute and careful observer, and his _renseignements_ on the topography of East Florida are well worth consulting. Among the notable passages is a vivid description of the remarkable meteoric shower of November 12, 1799, which he encountered off the south-western coast of Florida, and from which, conjoined with the observations of Humboldt at Cumana, and others, the periodicity of this phænomenon was determined by Palmer, of New Haven. A geographical account of Florida is said to have appeared at Philadelphia about this time, from the pen of John Mellish,[87] but unless it forms merely a part of the general geography of that author, I have been able to find nothing of the kind in the libraries of that city. The article on Florida in the important work on America of Antonio de Alcedo,[88] derives some importance from the list of Spanish governors it contains, which, however, is not very perfect; but otherwise is of little service.
