California certainly will contribute something to the support of this great enterprise, but cannot, by any means, constitute the chief inducement to its construction. Her gold will of course come more rapidly, readily and safely across the continent than around Cape Horn. In this respect, the saving to the consignees on the Atlantic coast will be very great, and will be represented by three items: saving of time, saving in the interest of money, and saving in consequence of the diminution of the risks of transportation. A glance at our table of casualties by sea, in a former chapter, will show how great the last named saving promises to be. That on the interest of money will also be great. It requires about three weeks to send from California by the shortest existing route to New Orleans, while, by the railroad, that city will be but a few days’ distant from San Francisco or San Diego. Allowing a week to be occupied in the trip, the saving in this item will amount to a half a month, and as a million is often brought in a single cargo, this is no trifle. At six per cent. per annum, it would amount to twenty-five hundred dollars on each shipment. The item of time will be sufficiently appreciated by the mercantile reader without comment from us.

These, however, are not the only benefits which the road may expect to derive directly from California. Much of the British commerce, which now finds its way to that distant region by the long routes, will go thither by the more direct and expeditious way of the new road. A way commerce will also inevitably spring up and there will be a cordon of settlements and towns stretching across a wilderness which years of ordinary immigration would be required to fill up. Branch roads would also soon start from the main trunk to various important regions along the route. The Santa Fe trade and the commerce of the prairies generally would soon seek this as its natural channel. The emigration to California would also largely benefit the road. This is likely to be large for some time to come, and the return tide would also contribute to increase the pecuniary revenue of this great national enterprise.

To California it would be of the greatest service, and the enlargement of the resources of that State would of course increase those of the improvement which causes the beneficial change. The country would then be settled from the east as well as from the west, and the gold of the Sierra Nevada would speedily be brought into market.

These advantages, considerable as they are, really form but a very small portion of the inducements to the construction of this important work. The great and important revenues of the road will come from far beyond the limits of the State. The enormous commerce of Eastern Asia and its Archipelago, which has enriched every nation that ever secured it, will then flow over our country leaving its golden sands behind it. China will send its teas, Amboyna its spices, Java its tin, Japan its copper, through our dominions. No commercial manœuvring, no diplomatic juggles can divert this mighty trade from its natural course. There is a destiny in commerce, as well as in other things, and fate seems determined to pour the riches of the world into our lap. If, in former times, the slow caravans which conveyed the treasures of the east to western ports, left wealth behind them, wherever their footprints were seen, though vexed by Tartar and by Arab plunderers, how much more benefit is likely to be derived from a rapid and safe transit through a civilized nation, ready, eager and able to add their quota to the stream of wealth?

We must not forget, also, that this eastern commerce is greater and more important than it ever was. Our efforts have unsealed Japan, and before long we shall be reaping the fruits of our enterprise in that quarter. Australia, too, is now ready to add her gold to a commerce already immensely valuable. China must open her doors still wider, for the world will knock loudly at them. Nor is this all. The whole trade of the western coast of South America must change its course. A Pacific capital is destined to absorb it. The whaling fleets of the Pacific will not have the stormy passage around Cape Horn to dread, but another New Bedford will look greasily upon the western ocean. The fur trade also will change its course. Oregon will furnish it with a port of departure, California with a permit of entry. Siberia itself may divide its trade between San Francisco and St. Petersburg. We seem to be on the point of taking the position which China has always claimed, and of becoming the true centre of the world, at least so far as commerce is concerned.

I believe it is now generally admitted that the Southern route is the most practicable—that it is the most level, the most fertile, the best watered, the best timbered, and that the climate through which it runs is the only one that is favorable at all seasons of the year. I have conversed with several gentlemen who passed over the various routes on their way to California, and they informed me that the mountainous parts of the northern routes are usually blocked up during the winter with immense drifts of snow, which lie upon the ground to the depth of from forty to fifty feet—sometimes much deeper. Those who traveled over the northern routes also complained of the scarcity of wood, water and provisions, and represented the Indians as being very hostile and treacherous; while, in most cases, those who traveled over the southern route experienced no hindrance, difficulty or impediment whatever, having had pleasure, peace and plenty all the way. But besides the advantages of climate, surface, soil, wood and water, there are other considerations which weigh in favor of the southern route. The distance is much shorter, and the population is more friendly, civilized and thrifty. It will bring us on more intimate terms with the Mexicans, and they will be induced to purchase larger quantities of our manufactured and imported merchandise.

Every southern man should feel a lively interest in this gigantic scheme, and enlist all his energies in aid of its completion. It affords one of the finest opportunities that the South has ever enjoyed for establishing her commercial independence, for counterbalancing the increasing commercial power of the North. In connection with this subject, I may here present an extract from a letter which I had the honor to receive, not long since, from one of the most sagacious and far-sighted patriots of the South. Speaking of the great Atlantic and Pacific Railway, among other things, he says: “North Carolina should not be an indifferent spectator of this noble enterprise. The port of Beaufort, unrivaled for health, possesses a depth of water sufficient for all convenient purposes; while the placid bosom of its well-protected harbor, justly entitles it to be styled the Pacific port of the Atlantic coast. Pursue its degree of latitude westward across the continent and the Pacific ocean, and you will find that degree passing near Memphis, Little Rock, Fulton, El Paso, and San Diego to Shanghai, the last two being the nearest ports of the two continents, in so low a latitude. Railways are chartered from Beaufort westward, and are constructed, or in progress of construction, that will reach perhaps one third or half way across the continent. May we not then hope, ere long, to see them uniting the two oceans?�

Experienced navigators have said that, in consequence of the favorable course of the tradewinds, the voyage can be accomplished between San Diego and Shanghai in about eight days’ less time than it can be between San Francisco and Shanghai; and this is certainly a very strong argument in favor of running the road directly to San Diego—leaving San Francisco to the right.

Since the above was written, the following abstract of the “Report of the Secretary of War on the several Pacific Railroad Explorations� has been published; and as it more than substantiates the correctness of my remarks, and imbodies a great deal of valuable information concerning the various routes, I hope the reader will peruse it with due care and attention. I here transcribe it, with brief comments, from the columns of the Herald:
