IDAHO.
This territory was organized March 3rd, 1863. It originally embraced a vast territory lying on both sides of the main chain of the Rocky Mountains; but the eastern portion has since been erected into the territory of Montana. It has about 90,000 square miles of territory, and had, in 1870, 14,998 inhabitants.
Idaho has very little history prior to the organization of its Territorial government. Its chief attraction to settlers lies in its mines, as yet, and the population is floating, and, in large part, rough and sometimes disorderly. The difficulty of reaching it has prevented its rapid growth. It is exceedingly rich in the precious metals and this will, in time, attract a large population. The eastern and northern parts are very mountainous, abounding in wild and striking scenery and in natural curiosities. The soil in the southern, central, and western parts, is fertile, producing wheat and other small grain, and vegetables very successfully, but is unfavorable for corn from the late frosts of spring and the early cold of autumn. Snow falls to a great depth in the mountains; but the streams are numerous, and there is much choice farming land, which may, ultimately, serve to support its mining population.
It runs from the northern boundary of Utah to the south line of British America; Washington Territory and Oregon, lying west. When railroads shall render it accessible, and open the way for its treasures to a market, it will be filled with an industrious and hardy population who will find all the elements of a prosperity as great as any section of the Union enjoys. It has three beautiful lakes—the Coeur d’Aline, the Pen d’Oreille, and the Boatman—of some size, and navigable for steamers. Boisé City is the capital.
MONTANA TERRITORY
Was organized May 26th, 1864. It lies among the Rocky Mountains, in part on the western slope, but extending into the eastern valleys; and contains the sources of the streams forming the Missouri river; while Idaho lies west among the Blue mountains where the tributaries of the Columbia rise.
Montana abounds in mines of gold and silver; and these are said to be much richer than those of California. The average yield of ores in the latter State is $20 per ton, but the average in Montana is stated to be four times that amount. Great as is the yield of gold mines here it is declared that the ease with which silver is separated from its combinations in the ore will make that branch of mining more profitable. Copper also abounds. This territory has several eminent advantages over other mining districts. It is reached by steamboats on the Missouri river, from St. Louis, without transhipment: navigation being free to Ft. Benton, in the heart of Montana. The river voyage from St. Louis to Ft. Benton, is made in 28 days.
There is a large and constant supply of water, a point of great difficulty in most of the other mining regions; and the country everywhere furnishes easy natural roads, the principal range of the Rocky Mountains not presenting the broken and rugged character of most other ranges. Associated with this point is the important fact of great agricultural capability. It is one of the best grazing regions west of the Mississippi. Small grain and fruit are grown with the greatest ease, as also the more important vegetables. There is abundance of timber for all purposes of home consumption.
The area is stated at 153,800 square miles. The population in 1870 was 20,594.
