Yet this Company performs this distant and difficult service with great regularity and at a low price. They have never lost a trip, a mail-bag, or a passenger by marine disaster during the eight years that they have been running in the Pacific. This results from the fact of the Company having thirteen steamers. If all of the steamers now in commission were sunk, they could supply their place from their reserve fleet and have no hiatus in their service. Such a spare fleet is an enormous expense; but it is positively indispensable to regular and highly efficient service. It is singular that under these circumstances they can perform the service at $1.70 cents per mile. It is a notorious fact that these steamers could not have supported themselves in 1854-55 without the aid which they obtained from the Government for the services which they performed. They never have transported much freight, as it would not bear the transhipment at Panama. The small quantity which they had was during the first years after the discovery of gold, and then only. They have never at any time brought any eastward. The Panama Railroad was a splendid consummation of which the world had dreamed for years, and toward whose completion this Company was highly instrumental. Yet it did not enable the steamers to transport freight, and it never will. These steamers run the 3,300 miles between Panama and San Francisco by a time-table. They arrive at either end within a very few hours of thirteen and a half days, including all of the stoppages, which are also made at specified hours. Thus the average speed of the steamers is about 254 miles per day. They touch at Acapulco and Mazanilla, and supply San Diego, Monterey, San Pedro, Santa Barbara, San Luis, and Obispo, ports of California, from Panama by a branch line. This is an extra service, and is not taken into account in calculating the mileage paid the Company. The steamers have carried probably 175,000 passengers to California, and have brought back about $200,000,000 in gold. They have also by their semi-monthly line from San Francisco to Oregon assisted in populating that rich and beautiful agricultural district, and making it available for useful purposes as a part of the United States. They have converted the wilderness of California into a smiling garden, and will ere long produce the same effect on Oregon. With that coast comparatively unprotected, and with the small standing army sustained in this country, they become very important as a ready means of concentrating on the Pacific coast a large army in a few days. They also afford a ready transit for the changing crews of our national vessels, which, when once around the Horn, may remain there several years; having to change their crews only.
