LATITUDE AND LONGITUDR. 15 better and more productive country through which to run, Of that I have already spoken.. But will they lengthen their route from the Missouri to San Fran- cisco by running round this labyrinth of mountains by a single grand detour, rather than by winding round them in detail, as they would have been compelled to do, had they adopted the other alternative? No man can answer that question yet. But if they have made it longer, they have also made it leveler, safer, and certainly more profit- able. I know that the impression generally prevails, that this southern route through New Mexico and Arizona will be longer than if it had been run through Utah and Nevada, But, after all, that impression may be erroneous. With much care I oe prepared the following table of the latitude and longitude of points on the two routes—that of the Kansas road, and that of the Platte, The points on the Union Pacific Railway of the Kansas are printed in Roman characters; those of the Union Pacific Railroad of the Platte in talics, Latitude and Longitude of the Principal Points on Both Routes.

And it will also be observed that the point at which the Platte route attains the summit of the Rocky Mountains is twenty-five geographical miles further north of San Francisco than Aubry, the extreme southern deflection of the Kansas route, is south of it. Again, it will be observed that the north bend of the Humboldt river is more than three degrees nearer to the meridian of San Fran- cisco than Aubry, while it is almost as far north as Aubry is south, A careful study of this table will shake the opinion that the southern line must necessarily be longer than the northern, even should the latter not he more tortuous, I do not assert that it is not longer,
