The western coast is in the contrary extreme, vary bold, and with few Islands; in describing these we shall commence on the north off the coasts of New California, where the first are the rocks, called in Spanish the _Farallones_, in 37° 48ʹ 10ʺ north latitude, and 123° 1ʹ west longitude. The next are the island of _Juan Rodriguez Cabrillo_, in 34° north latitude, and 120° 31ʹ west longitude. The island of _San Nicholas_ in 33° 16ʹ north latitude, and 119° 30ʹ west longitude. The island of _San Salvador_ in 32° 43ʹ north latitude, and 118° 30ʹ west longitude. Island of _St. Martin_, or _de los Coronados_, a small groupe in 32° 25ʹ north latitude, and 117° 18ʹ west longitude. Island of _San Bernardo_ in 29° 40ʹ north latitude, and 115° 56ʹ west longitude. Island of _Guadalupe_ in 28° 53ʹ north latitude, and 118° 17ʹ west longitude. This last island is about thirteen miles long, composed of high, rocky and naked mountains with two small islands, one about a mile west south-west and the other two miles south of its southern point. The latitude and longitude are that of its southern cape, the island itself running thirteen miles farther to the north. The island of _San Benito_ is small and surrounded with shoals; it is mountainous, and its highest part is in 28° 18ʹ north latitude, 115° 46ʹ west longitude. Island of _Cedros_ in 28° 2ʹ north latitude, and 115° 23ʹ west longitude. To the south, off the coast of Old California, the islands are not so numerous; there are however, several very small ones in some of the bays, and near the bay of La Magdalena one large one, named _La Margarita_, of which nothing is known excepting that it is about forty or fifty miles in length, and hilly. On the east coast of Old California are several small islands, much used in the former pearl fishery; of these, proceeding from Cape St. Lucas to the extremity of the Vermillion Sea, are the islands _Cerralbo_ and _del Espiritu Santo_, near the Mission de la Paz; islands of _San Francisco_, and _San Jose_, with several smaller ones. Island of _Santa Cruz_, island of _Montserrat_, and island of _Catalina_, near Puerto Escondido, and a large island near the coast of the Mission of Loretto; of these _Santa Cruz_ is famous, as having been the abode of Cortez during his expedition to California; he remained on it a considerable time, suffering dreadful hardships, and losing the greater part of his followers by famine and disease. Santa Cruz is in 25° 23ʹ north latitude, and 110° 47ʹ west longitude. Island of _St. Lorenzo_ opposite Tiburon isle, and the Island of _Santa Ines_, or _Angel de la Guarda_, a fine and extensive tract. In the estuary of the Gila and Colorado, at the extremity of the gulf, another large island appears, but of it nothing certain is known; descending the gulf of California on the eastern shore, off the province of Sonora, are the islands of _Tiburon_, _Tortuga_, _Lobos_, _San Ignacio_, and several smaller ones.
