commodities, and her commercial advantages must soon make her one of our most populous States. New Mexico, though situated in the interior and without a seacoast, is known to contain much fertile land, to abound in rich mines of the precious metals, and to be capable of sustaining a large population. From its position it is the intermediate and connecting territory between our settlements and our possessions in Texas and those on the Pacific Coast. Upper California, irrespective of the vast mineral wealth recently developed there, holds at this day, in point of value and importance, to the rest of the Union the same relation that Louisiana did when that fine territory was acquired from France forty-five years ago. Extending nearly ten degrees of latitude along the Pacific, and embracing the only safe and commodious harbors on that coast for many hundred miles, with a temperate climate and an extensive interior of fertile lands, it is scarcely possible to estimate its wealth until it shall be brought under the government of our laws and its resources fully developed. From its position it must command the rich commerce of China, of Asia, of the islands of the Pacific, of western Mexico, of Central America, the South American States, and of the Russian possessions bordering on that ocean. A great emporium will doubtless speedily arise on the Californian coast which may be destined to rival in importance New Orleans itself. The depot of the vast commerce which must exist on the Pacific will probably be at some point on the Bay of San Francisco, and will occupy the same relation to the whole western coast of that ocean as New Orleans does to the valley of the Mississippi and the Gulf of Mexico. To this depot our numerous whale ships will resort with their cargoes to trade, refit, and obtain supplies. This of itself will largely contribute to build up a city, which would soon become the center of a great and rapidly increasing commerce. Situated on a safe harbor, sufficiently capacious for all the navies as well as the marine of the world, and convenient to excellent timber for shipbuilding, owned by the United States, it must become our great Western naval depot.
