The States and Territories on the line of the Union and Central Pacific Railroad -- or immediately tributary to it -- contained a population in 1860 of only 554,301, with 132 miles of telegraph line and 32 miles of railway. This same scope of country contained a population, according to the census of 1870, of 1,011,971, and it is now encompassed by over 13,000 miles of telegraph lines and 4,192 miles of railroads completed, and many more in progress, in which are invested the enormous capital of Three Hundred and Sixty-three Millions Seven Hundred and Fifty Thousand Dollars. Should we add to the above the immense amount of capital invested -- within the same ten years -- in quartz mills, smelting furnaces, development of mines, and other resources of the country, the grand total would be truly astonishing.

We have the official figures, exhibiting the improvements within an area of two miles of each town on the line of the Union Pacific Railroad -- furnished us by J. M. Eddy, Esq., of the Town Lot Department -- which show that $1,798,810 has been expended for buildings and 1,293 new ones have been erected. With this large expenditure for buildings alone, what must be the amount for agricultural and other purposes?

Where, but a few years ago, the buffalo and other game roamed in countless thousands, and the savages skulked in the canyons and secret hiding-places where they could pounce out unawares upon the emigrant -- the hardy pioneer who has made the wilderness, if not "to blossom like the rose," a safe pathway for the present generation, by laying down their lives in the cause of advancing civilization -- now are to be seen hundreds of thousands of hardy emigrants, with their horses, cattle, sheep, and domestic animals, and the savages are among the things that have "moved on."
