delivered the opinion of the court.

The grant to the Burlington and Missouri River Railroad Company, by the act of- Congress of July 2,1864, c. 216, was of ten sections of land for every mile on each side of the line of its road when located, such sections to be designated by. odd numbers, and the land to be only taken which, at the ,timé’ the line was definitely fixed, had not been sold, reserved, ■ or otherwise disposed of by the United States, and to which a pre-emption or homestead claim had not attached. .The grant *331 was one of quantity, without any designation, in express terms, of any lateral limit on either side of the road, within which the land was to be selected. In this resp.ect it differed from nearly all other grants of land made by-Congress in aid of the'construction of railroads. • Other grants usually prescribed a lat-eral limit. The omission in that case was not accidental. Nearly all the land within the distance usually, prescribed as a limit had already been disposed.of to, another- railroad company, or, from the general settlement of the country, was likely to be appropriated before the line of the road could be definitely located. In order, therefore, that its proposed aid might not be defeated, Congress allowed'the land granted to be taken on the line of the road wherever -it could be found, without regard to the distance from its line to which the grantee'might-be compelled to go'to' satisfy its grant,' by reason- of previous' appropriations.

Although there' was no express limitation of the distance from the road in which the land was to be selected, it was necessarily implied that the Selection should be made of alternate sections nearest the road, of which the land had'not been previously sold, reserved, or otherwise-disposed of. The company was not at liberty to pass beyond land open to its appropriation, and take lands farther removed from its road. In all grants which are to be satisfied out of sections along a line of a road, it is necessarily implied, in the absence of specific designation otherwise, that the land is to be taken from the-nearest undisposed sections of- the character mentioned. Such' grants give no license to the grantees to roam over the whole public domain lying' on either side , of the road, in search of land desired.' The grants must be satisfied out of the first land found which meets the conditions named.

The line of the defendant’s road was definitely located in June, 1865. The land consisting of .the alternate sections designated by odd numbers within a limit of twenty miles was withdrawn from sale in July following, and so much of it as had not been previously sold, reserved, or otherwise disposed' of, or to which a homestead or a pre-emption claim had not attached, was thus appropriated to the satisfaction of the grant. It could not be subsequently applied to other purposes or *332 devoted to the claim of private,parties. ■ It was immediately taken by the grant, and’would have-been Sufficient to satisfy it in full, if no portion of the odd sections had been: previously disposed of, or subjected- to- other -claims. -And the grantee could only go beyond that limit when it was found that there was a deficiency remaining..after- all within it had been appror priated.

. The grant was one in preesenti, and when the sections granted were ascertained, the title to the land took effect by. relation as of its date, except as to the reservations named. The land to which the complainant asserts a homestead, claim is embraced in one of the sections within the twenty-mile limit ;■ his claim, therefore, necessarily falls before, the superior right of the company. Its estate had become. vested when he took the initiatory steps to secure a homestead right.-. ■

The contention of the complainant, so far as we can understand his position, is this: That as there was no lateral limit expressed in the act of Congress, within which the land granted was to be selected, therefore it might be-seleeted.at any distance from the road, and- that no appropriation could be considered as made, or any estate deemed to be vested,.until the sections were actually selected, that is, until the patent of the United States was issued. This notion arises from a misconception, of the language of our decision in the case .of the United States against the same. company, reported in 98th U. S. It there appeared that within the twenty-mile , limit there was not sufficient unappropriated land to-meet the grant, and accordingly the company made application to the Land Department, for land outside of that limit for the- balance, and patents for such balance were issued to it. A suit was afterwards brought by the United States to cancel those patents. We there held, as in this case, that the grant was one of quantity, and we observed that the land was subject.only to these limitations: First, that the land must.be embraced by the. odd section’;, second, that it must be taken in equal quantities on each side of the road; third, that it must be on the line of the road; and, fourth, that it must not have been sold, reserved, or otherwise disposed of .by the United States, and a pre-emption or homestead claim must not have attached to it at the time the *333 line was .located." And we said that the terms of the grant did not require the land to be contiguous to the road; and if not contiguous, it was not easy to say at what distance the land-to. be selected would cease to be along the line. . This language' was-used with reference:to the-objection in the case, that- land could not be'taken beyond the twenty-mile limit, where all within that limit had been previously exhausted. We did not intend to intimate that the land granted could'be taken at any distance, without regard to previous appropriations, but only that land could be .thus taken where, from previous appropriations, as in that case, -the grant could not otherwise be satisfied.

Decree affirmed.
