The Territories of the Union are generally in a condition of prosperity and rapid growth. Idaho and Montana, by reason of their great distance and the interruption of communication with them by Indian hostilities, have been only partially organized; but it is understood that these difficulties are about to disappear, which will permit their governments, like those of the others, to go into speedy and full operation. As intimately connected with and promotive of this material growth of the nation, I ask the attention of Congress to the valuable information and important recommendations relating to the public lands, Indian affairs, the Pacific Railroad, and mineral discoveries contained in the report of the Secretary of the Interior which is herewith transmitted, and which report also embraces the subjects of patents, pensions, and other topics of public interest pertaining to his Department. The quantity of public land disposed of during the five quarters ending on the 30th of September last was 4,221,342 acres, of which 1,538,614 acres were entered under the homestead law. The remainder was located with military land warrants, agricultural scrip certified to States for railroads, and sold for cash. The cash received from sales and location fees was $1,019,446. The income from sales during the fiscal year ending June 30, 1864, was $678,007.21, against $136,077.95 received during the preceding year. The aggregate number of acres surveyed during the year has been equal to the quantity disposed of, and there is open to settlement about 133,000,000 acres of surveyed land. The great enterprise of connecting the Atlantic with the Pacific States by railways and telegraph lines has been entered upon with a vigor that gives assurance of success, notwithstanding the embarrassments arising from the prevailing high prices of materials and labor. The route of the main line of the road has been definitely located for 100 miles westward from the initial point at Omaha City, Nebr., and a preliminary location of the Pacific Railroad of California has been made from Sacramento eastward to the great bend of the Truckee River in Nevada. Numerous discoveries of gold, silver, and cinnabar mines have been added to the many heretofore known, and the country occupied by the Sierra Nevada and Rocky mountains and the subordinate ranges now teems with enterprising labor, which is richly remunerative. It is believed that the product of the mines of precious metals in that region has during the year reached, if not exceeded, one hundred millions in value.
