The insurgents of Spanish America have lately been carrying on some operations in this quarter, and have established themselves in Amelia Island, at a town called Fernandina, where they have built batteries for their defence, and to whose port they carry many of the prizes they make of the Spanish merchant vessels in the West Indian seas. They are principally European adventurers, who have raised a flag in Amelia Island, which they display occasionally in their predatory incursions on the neighbouring continent; on this flag is a green cross, designated by them the green cross of the Floridas; they have hitherto been unsuccessful in their efforts, and have not been assisted by the Colonists. The government of the United States, have lately taken forcible possession of this port. The expences of the administration of Florida are disbursed from the treasury of Mexico, the situado or annual remittance for this purpose being sent by way of the Havannah to Pensacola, and amounting in general to the sum of 62,700_l._ sterling. This sum is usually remitted to the intendant or governor of Pensacola. _NEW SPAIN._ The most important of all the kingdoms of Spanish America, is New Spain; therefore, before commencing with a detailed description of its boundaries and situation, we shall give a concise view of those circumstances which are of most importance, with respect to its history, colonization, &c. Under the title of Viceroy of New Spain, a Spanish officer of the highest rank governs a territory, which, in Europe, would be designated as an empire; for it comprehends a surface extending from the thirty-ninth to the sixteenth degree of north latitude; in its broadest part, occupying 22 degrees of longitude, and is washed by the waters of the Great Pacific on its western, and by those of the Mexican Gulf, or Atlantic Ocean, on its eastern shores; having unknown lands to its north; the republic of the United States of America to its east; and the government of Guatimala, as its southern limit; thus occupying one of the most advantageously situated positions in the political world, whether for the facilities afforded to its commerce, by the vicinity of two oceans, or by its stretching through part of the Torrid and Temperate Zones, affording from the heat of the one, the luxuries of the East, and from the mildness of the other, the necessaries of human existence in the most profuse abundance; here too exist more mines of silver and gold, of copper, tin, &c., than in any other part of America; whilst its western shores afford the pearl muscle, equal, if not superior, to the celebrated produce of Ormus and Ceylon. That enterprizing and enlightened traveller, M. le Baron de Humboldt, states the population of this viceroyalty of Mexico, or New Spain, to have exceeded, in the year 1806, six millions five hundred thousand souls; and its surface to extend over a space equal to 118,748 square leagues, at twenty-five leagues for each degree.
