The Spanish government have set up an inadmissible claim to the whole western coast, but, as much doubt has existed on the claims of the two nations, 39° north latitude, has been usually taken as the boundary of Spanish acquisitions in the New World; because they have some settlements in that latitude to the north of the town of Santa Fé, in New Mexico, as well as because the sources of the Rio Bravo are situated thereabouts. Therefore, commencing from the coast of the Pacific in 39° north latitude, we draw an ideal line from that parallel across the country, until we have passed the province of New Mexico; thence the line bends southward and eastward, until it meets the River Mexicano, or Mermento, which it follows to the Gulf of Mexico; where, in this quarter, the boundaries are again disputed by the government of the United States; who, since Louisiana has been ceded to them, lay claim to the whole country, up to the eastern bank of the Rio Bravo del Norte; the Spaniards, however, do not admit this, and fix their boundaries at the estuary of the Mexicano, or Mermento. A reference to the accompanying map will better explain those disputed limits than any verbal account. The western barrier of Spanish territory in North America, is the Pacific Ocean; on the south east, the Gulf of Mexico, the Bay of Honduras, and the Caribbean Sea, are the boundaries established by nature; and on the south, a chain of mountains called the Sierro de Canatagua, which run across the extremities of the two provinces of Veragua and Panama, in about 80° 50ʹ west longitude. This chain divides the northern from the southern continent of America, and the country is here known by the geographical name of the Isthmus of Darien. The extent of these possessions may be computed, by taking 7° north latitude, as the southern extremity, and 39° as the northern, which will give about 1900 miles in length, whilst from the varying form of the country in the Isthmus of Darien, the cutting out of Louisiana, the singular figure of the Floridas, and the immense inlet of the Californian Gulf, it may be computed at about 450 miles in mean breadth. POLITICAL DIVISIONS. THIS vast extent of continent, including the two West India islands of Porto Rico, and Cuba, is divided into four great governments. The viceroyalty of New Spain, or Mexico, the Capitania general of Guatimala, and the two Capitanerias Generales of Porto Rico and Cuba, which last includes the Floridas. TERRITORIAL DIVISIONS. THE face of the Spanish dominions in the North American Continent, is divided into three great sections; on the east, Florida; in the centre, north and west, New Spain; and on the south, Guitamala; we shall therefore proceed to give a separate description of each division, and its local divisions; commencing on the east with the government of the Floridas. _FLORIDA._
