The company was also granted ten alternate sections per mile of public land on each side of the railroad on the line thereof, and within the limits of 20 miles on each side of the road. The government undertook to extinguish Indian titles, but did not include in its grant mineral lands except coal and iron lands, or lands sold, reserved, or otherwise disposed of by the United States, or lands to which a pre-emption, homestead, swamp-land, or other lawful claim might have attached at the time the line of the road should have been definitely fixed. The grant was thus not of a specified number of acres, and no compensation was provided to the company for lands which might prove to be occupied; but in order to prevent speculation and in a measure to safeguard the company’s interests, it was provided that at any time after the passage of the act, and before July 1, 1865, without waiting for definite location of the road, the company might designate the general route and file a map, whereupon the Secretary of the Interior should cause the lands within 25 miles of said route to be withdrawn from pre-emption, private entry, and sale. When any portion of the route should be finally located, the Secretary of the Interior should cause the granted lands to be surveyed and set off so far as might be necessary. As a matter of fact, Judah filed his map and general designation before he left Washington in 1862. Lands were to be conveyed to the company on completion of stretches of 20 consecutive miles. A special clause, never enforced, provided that all granted lands not sold or disposed of by the company within three years after the entire road should have been completed, should be subject to settlement and pre-emption like other lands, at a price not exceeding $1.25 per acre to be paid to the company.
