The principal mountains west of the eastern boundary of California (the Rocky Mountains) are the Bear River, Wahsatch, Utah, the Sierra Nevada, and the Coast range. The Wahsatch Mountains form the eastern rim of the "great interior basin." There are numerous ranges in this desert basin, all of which run north and south, and are separated from each other by spacious and barren valleys and plains. The Sierra Nevada range is of greater elevation than the Rocky Mountains. The summits of the most elevated peaks are covered with perpetual snow. This and the coast range run nearly parallel with the shore of the Pacific. The first is from 100 to 200 miles from the Pacific, and the last from forty to sixty miles. The valley between them is the most fertile portion of California. Upper California was discovered in 1548, by Cabrillo, a Spanish navigator. In 1578, the northern portion of it was visited by Sir Francis Drake, who called it New Albion. It was first colonized by the Spaniards, in 1768, and formed a province of Mexico until after the revolution in that country. There have been numerous revolutions and civil wars in California within the last twenty years; but up to the conquest of the country by the United States in 1846, Mexican authority has generally been exercised over it. The following description of the political and social condition of Upper California in 1822 is extracted and translated from a Spanish writer of that date. I have thought that the extract would not be uninteresting:-- "_Government_.--Upper California, on account of its small population, not being able to become a state of the great Mexican republic, takes the character of territory, the government of which is under the charge of a commandant-general, who exercises the charge of a superior political chief, whose attributes depend entirely upon the president of the republic and the general congress. But, to amplify the legislation of its centre, it has a deputation made up of seven vocals, the half of these individuals being removed every two years. The superior political chief presides at their sessions. The inhabitants of the territory are divided amongst the presidios, missions, and towns. "_Presidios_.--The necessity of protecting the apostolic predication was the obligatory reason for forming the presidios, which were established according to circumstances. That of San Diego was the first; Santa Barbara, Monterey, and San Francisco were built afterwards. The form of all of them is nearly the same, and this is a square, containing about two hundred yards in each front, formed of a weak wall made of mud-bricks. Its height may be four yards in the interior of the square, and built on to the same wall. In its entire circumference are a chapel, storehouses, and houses for the commandant, officers, and troops, having at the entrance of the presidio quarters for a _corps-de-garde_.
