railroad companies, of which the Western Pacific, by subsequent legislation, became one, every alternate section of public land designated by odd numbers, within ten miles of each side of their respective roads, not sold, reserved, or otherwise disposed of by the United States, and to which a homestead or pre-emption claim may not have attached at the time the, line of the road is definitely fixed. It requires that, within a prescribed time, a map designating the general route of each road shall be filed in the Department of the Interior, and that the Secretary thereof shall-then cause the lands within a certain distance from such route to be withdrawn from pre-emption, private entry, and sale. The precise date when the Western Pacific Company filed its map is not stated in the record; but we infer that it was between the first day of the December Term (1864) of this court and the thirteenth day of February, 1865. At all events, the withdrawal for this road was made on the 31st of January, 1865; and our records show that the Moquelamos grant, which had been regularly presented to the commissioners, under- the act of March 3,1851, and duly prosecuted by appeal, was rejected here Feb. 13, 1865. It is a conceded fact, that the lands embraced by it fall within the limits of the railroad grant, which were enlarged by the amendatory act of 1864 (13 Stat. p.,358). This act also declares that any lands granted by it, or the act to which it is an amendment, “ shall not defeat or impair any pre-emption, homestead, swamp-land, or other lawful claim, nor include any government reservation or mineral lands, or the improvements of any bona fide settler.”
There can be no doubt that, by the withdrawal, the grant took effect upon such odd-numbered sections of public lands within the specified limits as were not excluded from its operation ; and the question arises, whether lands within the boundaries of an alleged Mexican or Spanish grant, which was then sub judice, are public within the meaning of the acts of Congress under which the patent, whereon the appellee’s title rests, was issued to the railroad company.
The subject of grants of land to aid in constructing works of internal improvement was fully considered at the present term, in Leavenworth, Lawrence, and Galveston Railroad Company v. United States, supra, p. 733. We held that they did not embrace
