bold, rocky shores of the peninsula are in continual view. The change of the temperature of the air is generally keenly felt by those who do not take care to provide against it. Within a few days after leaving Panama, the thermometer falls from 95° to 55°, and such a change must have an injurious effect, if additional clothing is not put on to meet it. The first portion of Upper California, or, the "Golden Land," which presents itself to the voyagers, is the Ceronados, two high, round-topped rocks off the port of San Diego. Then the beautiful, semi-circular harbor is entered, and if wanting, supplies are obtained from the town. From the harbor of San Diego, the vessel proceeds along the coast of California, and the towering peaks of the coast range of mountains, engage the attention. The high promontory of St. Vincent is passed, and then the open bay of Monterey is entered, and passengers are either let off the steamer or taken aboard as necessity may occasion. From Monterey the steamer keeps along the coast, and mountainous shores alone meet the view, until the voyagers come in sight of the Farallones, two large detached rocks at the southern side of the entrance to the bay of San Francisco. Then the Golden Gate, as the strait or entrance is called, is entered by the steamer, and the perpendicular cliffs and hills upon each shore afford matter for wonder. The strait is about three miles long, and from one to two miles broad. As the vessel reaches its terminus, the great bay of San Francisco opens to the view, looking like a miniature ocean. Bird Island, Wood Island, Angel Island, with the beautiful little bay of Sancelito, successively meet the gaze, and very soon the steamer is anchored, having reached her destination. Such is the Isthmus route to the "gold region." It is the shortest route, or the one which occupies the least time in traversing, presents great variety, and upon the whole, its beauties and pleasures outnumber the difficulties and annoyances. THE OVERLAND ROUTE. We now proceed to give the general character and direction of that which is considered the best land route to California, and which is the most travelled by emigrants. The principal advantage possessed by this route may be stated in a few words. It is the shortest route to the bay of San Francisco and the gold region. The Indians upon the route are friendly and very few acts of hostility have been committed. The trail is plain and good where there are no physical obstructions. To these must be added the certainty of the emigrants reaching their place of destination, in good season; which will not exist, if new and unexplored routes are attempted. The greatest calamities and sufferings have been endured by those who have either taken an entirely different route, or deviated from the line which we will describe. Advice concerning the time of starting, preparations, &c., will be interspersed in the description.
