(St.) DE LA FRONTERA, a town of South America, in Chili, in the province of Chiquito, near the lake Guanacho. The territory of this town is inhabited by 20,000 native Americans, who are tributary to Spain. It contains mines of gold, and produces a kind of almonds that are very delicate. It is seated at the foot of the Andes, in W. Long. 66° 35'. S. Lat. 23° 25'.

Juan de Porto Ricco, an island of America, and one of the Caribbes, being 100 miles in length, and 50 in breadth. It belongs to the Spaniards; and is full of very high mountains, and extremely fertile valleys, interspersed with woods, and well watered with springs and rivulets. It produces sugar, rum, ginger, corn, and fruits; partly proper to the climate, and partly introduced from Spain. Besides, there are so many cattle, that they often kill them for the sake of the skins alone. Here are a great number of uncommon trees, and there is a little gold in the north part of the island. It is commonly said that the air is healthy; and yet the earl of Cumberland, when he had taken this island, lost most of his men by sickness; and for that reason was forced to abandon it. This happened in the reign of Queen Elizabeth. It is subject to storms and hurricanes, like the rest of these islands. It lies to the east of Hispaniola, at the distance of 50 miles.

Juan de Porto Ricco, the capital town of the island of Porto Ricco, with a good harbour defended by several forts, and a bishop's see. It is seated on the north coast of the island, in W. Long. 65° 35'. N. Lat. 18° 30'.
