The officer who commands at this island is sent from Chili, in which government it is included, and the island is called _La de Tierra_ by the Spaniards, on account of its lying nearer the shore of Chili than the next largest, which is distinguished by the name of _Mas-afuera_, or the farthest, and is 80 miles west from Juan Fernandez, in 80° 46' west longitude, and 33° 45' south latitude. This last is very high and mountainous, and at a distance appears one hill; its form is triangular, and seven or eight leagues in circuit; the southern part is much the highest, and on the north end are some clear spots, but the rest is covered with wood. Several parts of the coasts of this isle afford good anchorage, but the bottom is generally deep; and it abounds in goats, which are easily caught and afford a good supply of fresh provision. On the south-west point of the island is a pierced rock, which proves a good mark for the anchorage on the western shore. Mas-afuera contains plenty of wood and fresh water, falling in cascades from the high ground of the interior; but these articles cannot be procured without difficulty, on account of the rocky nature of the shore causing the surf to beat violently. Several birds, and amongst these large hawks, are seen on the land, and hovering over the fish which abound on the shores, and may be easily caught. Sea wolves, seals, and other aquatic animals, are also very common. Off the south-western extremity of Juan Fernandez is a small uninhabited isle, or rather rock, named Isla de Cabras, or Isle of Goats. These islands are noted for having been the residence of two persons whose adventure gave rise to the novel of Robinson Crusoe. The one was a Mosquito Indian left there by the Buccaneers, and the other Alexander Selkirk, a Scotchman, also left there by his ship, and who lived four or five years on Juan Fernandez, subsisting upon the goats he caught, which were introduced into the islands by Fernandez, the discoverer, who settled and died in La de Tierra. In proceeding to the north from these, the next isles of any consequence off the coasts of Peru, are those named _St. Felix_ and _St. Ambrose_; but these are mere rocks of some extent and very high, on which innumerable seals and marine animals are found. They are not more than five miles in circumference, and are four leagues and a half distant from each other, between 26° 19' and 26° 13' south latitude, and between 79° 41' and 79° 26' west longitude.
