Mr. Justice Stevens
delivered the opinion of the Court.
The State of Utah claims the right to select extremely valuable oil shale lands located within federal grazing districts in lieu of and as indemnification for original school land grants of significantly lesser value that were frustrated by federal pre-emption, or private entry, prior to survey. The question presented is whether the Secretary of the Interior is obliged to accept Utah’s selections of substitute tracts of the [502] same size as the originally designated sections even though there is a gross disparity between the value of the original grants and the selected substitutes. We hold that the Secretary’s “grossly disparate value” policy is a lawful exercise of the broad discretion vested in him by § 7 of the Taylor Grazing Act of 1934, 48 Stat. 1272, as amended in 1936, 49 Stat. 1976, 43 U. S. C. § 315f, and is a valid ground for refusing to accept Utah’s selections.
Utah became a State in 1896. In the Utah Enabling Act of 1894, Congress granted Utah, upon admission, four numbered sections in each township for the support of public schools. The statute provided that if the designated sections had already “been sold or otherwise disposed of” pursuant to another Act of Congress, “other lands equivalent thereto . . . are hereby granted.” The substitute grants, denominated “indemnity lands” were “to be selected within the State in such manner as [its] legislature may provide with the approval of the Secretary of the Interior.” 1
Because much of the State was not surveyed until long-after its admission to the Union, its indemnity or “in lieu” selections were not made promptly. On September 10, 1965, [503] Utah filed the first of 194 selection lists with the Bureau of Land Management of the Department of the Interior covering the land in dispute in this litigation. The 194 indemnity-selections include 157,255.90 acres in Uintah County, Utah, all of which are located within federal grazing districts created pursuant to the Taylor Grazing Act.
In January 1974, before Utah’s selection lists had been approved or disapproved, the Governor of Utah agreed that the Secretary of the Interior could include two tracts comprising 10,240 acres of selected indemnity lands in an oil shale leasing program, on the understanding that the rental proceeds would ultimately be paid to the State if its selections were approved. The proceeds of the leases are of substantial value.2
In February 1974, the Secretary advised the Governor that he would not approve any indemnity applications that involved “grossly disparate values.” 3 He wrote:
“As you know, the Department of the Interior has not as yet acted upon the State’s [indemnity] applications. The principal question presented by the applications is whether pursuant to Section 7 of the Taylor Grazing Act, 48 Stat. 1272 (1934), as amended, 43 U. S. C. § 315f (1972), the Department may refuse to convey applied-for lands to a State where the value of those lands greatly exceeds the value of the lost school lands for which the State seeks indemnity. In January 1967, the then Secre[504] tary of the Interior adopted the policy that in the exercise of his discretion under, inter alia, Section 7 of the Taylor Grazing Act, he would refuse to approve indemnity applications that involve grossly disparate values. That policy remains in effect.
“In the present case, although the land values are not precisely determined, it appears that the selections involve lands of grossly disparate values, within the meaning of the Department’s policy. While the Department is not yet prepared to adjudicate the State’s applications, I feel it is appropriate at this time to advise you that we will apply the above-mentioned policy in that adjudication.” 4
The State promptly filed this action in the United States District Court for the District of Utah. The facts were stipulated, and Judge Ritter entered summary judgment in favor of the State. He held that if Utah’s selections satisfy all of the statutory criteria governing indemnity selections when filed,5 the Secretary has no discretion to refuse them [505] pursuant to a “grossly disparate value” policy. The Court of Appeals for the Tenth Circuit affirmed, Utah v. Kleppe, 586 F. 2d 756 (1978), holding that § 7 of the Taylor Grazing [506] Act gave the Secretary no authority to classify land as eligible for selection and that the State had a right to select indemnity land of equal acreage without regard to the relative values of the original grants and the indemnity selections.
Because the dispute between the parties involves a significant issue regarding the disposition of vast amounts of public lands,6 we granted certiorari. 442 U. S. 928. We believe that the Court of Appeals and the District Court failed to give proper effect to the congressional policy underlying the provision for indemnity selection, and specifically misconstrued § 7 of the Taylor Grazing Act as amended in 1936. We therefore reverse.
I
The Enabling Act of each of the public-land States admitted into the Union since 1802 has included grants of designated sections of federal lands for the purpose of supporting public schools.7 Whether the Enabling Act contained words of present [507] or future grant, title to the numbered sections did not vest in the State until completion of an official survey. Prior to survey, the Federal Government remained free to dispose of the designated lands “in any manner and for any purpose consistent with applicable federal statutes.” 8 In recognition of the fact that the essentially random grants in place might therefore be unavailable at the time of survey for a variety of reasons,9 Congress authorized grants of indemnity or “lieu” lands of equal acreage.
As Utah correctly emphasizes, the school land grant was a “solemn agreement” which in some ways may be analogized to a contract between private parties. The United States agreed to cede some of its land to the State in exchange for a commitment by the State to use the revenues derived from the land to educate the citizenry.
The State’s right to select indemnity lands may be viewed as the remedy stipulated by the parties for the Federal Gov[508] ernment’s failure to perform entirely its promise to grant the specific numbered sections. The fact that the Utah Enabling Act used the phrase “lands equivalent thereto” and described the substituted lands as “indemnity lands” implies that the purpose of the substitute selections was to provide the State with roughly the same resources with which to support its schools as it would have had had it actually received all of the granted sections in place.10 Thus, as is typical of private contract remedies, the purpose of the right to make indemnity selections was to give the State the benefit of the bargain.
The history of the general statutes relating to land grants for school purposes confirms this view. ■ Thus, for example, in 1859, when confronted with the fact that many settlers had occupied unsurveyed lands that had been included in school grants, Congress confirmed the settlers’ claims and granted to the States “other lands of like quantity.” Ch. 58, 11 Stat. 385. The substitution of an equal quantity of land provided the States a rough measure of equal value.
The school land grants gave the States a random selection of public lands subject, however, to one important exception. The original school land grants in general, and Utah’s in particular, did not include any numbered sections known to be mineral in character by the time of survey. United States v. Sweet, 245 U. S. 563. This Court so held even though the Utah Enabling Act “neither expressly includes mineral lands nor expressly excludes them.” Id., at 567. The Court’s opinion stressed “the practice of Congress to make a distinction between mineral lands and other lands, to deal with them [509] along different lines, and to withhold mineral lands from disposal save under laws specially including them.” Ibid. Mineral lands were thus excluded not only from the original grants in place but also from the indemnity selections.11 Since mineral resources provide both the most significant potential source of value and the greatest potential for variation in value in the generally arid western lands, the total exclusion of mineral lands from the school land grants is consistent with an intent that the States’ indemnity selections of equal acreage approximate the value of the numbered sections lost.
In 1927, some nine years after the decision in United States v. Sweet, supra, Congress changed its policy to allow grants of school lands to embrace numbered sections that were mineral in character.12 But the 1927 statute did not expand the kinds of land available for indemnity selections.13 Thus, after 1927 even if the lost school lands were mineral in character, a State was prohibited from selecting mineral lands as indemnity. It was not until 1958 that Congress gave the States the right to select mineral lands to replace lost school lands, and that right was expressly conditioned on a determination that the lost lands were also mineral in character. 72 Stat. 928, 43 U. S. C. § 852. See n. 5, supra. For 30 years, then, States [510] were not even permitted to select lands roughly equivalent in value to replace lost mineral lands. The condition in the 1958 statute, that the lost lands be mineral in character before mineral lands could be selected as indemnity, rather clearly reflects an intention to restore the character of the indemnity selection as a substitute of roughly equal value.14
Throughout the history of congressional consideration of school land grants and related subjects — a history discussed at great length in the voluminous briefs submitted to us — we find no evidence whatever of any congressional desire to have the right to select indemnity lands do anything more than make the States whole for the loss of value resulting from the unavailability of the originally designated cross section of lands within the State. There is certainly no suggestion of a purpose at any time, including 1958, to allow the States to obtain substantially greater values through the process of selecting indemnity land.
Thus, viewing the program in this broad historical perspective, it is difficult to identify any sensible justification for Utah’s position that it is entitled to select any mineral lands it chooses regardless of the value of the school sections lost. Nevertheless, Utah is quite correct in arguing that the Secretary has no power to reject its selections unless Congress has given it to him. We have no doubt that it has.
II
Prior to the 1930’s, cases in this Court had made it perfectly clear that the Federal Government retained the power to appropriate public lands embraced within school grants for other [511] purposes if it acted in a timely fashion. On the other hand, it was equally clear that the States’ title to unappropriated land in designated sections could not be defeated after survey, and that their right to indemnity selections could not be rejected if they satisfied the statutory criteria when made, and if the selections were filed before the lands were appropriated for other purposes. The authority of the Secretary of the Interior was limited to determining whether the States’ indemnity selections met the relevant statutory criteria. See Wyoming v. United States, 255 U. S. 489; Payne v. New Mexico, 255 U. S. 367, 371.
In the 1930’s, however, dissatisfaction with the rather loose regime governing use and disposition of unappropriated federal lands, prompted mostly by the waste caused by unregulated stock grazing,15 led to a series of congressional and executive actions that are critical to this case. By means of these actions, all unappropriated federal lands were withdrawn from every form of entry or selection. The withdrawal did not affect the original school land grants in place, whether or not surveyed, but did include all lands then available for school indemnity selections. The lands thus withdrawn were thereafter available for indemnity selections only as permitted by the Secretary of the Interior in the exercise of his discretion.
The sequence of events was as follows. In 1934, Congress enacted the Taylor Grazing Act “[t]o stop injury to the public grazing lands by preventing overgrazing and soil deterioration, to provide for their orderly use, improvement, and development, to stabilize the livestock industry dependent upon the public range, and for other purposes.” 48 Stat. 1269. Section 1 authorized the Secretary of the Interior to establish grazing districts in up to 80 million acres of unappropriated federal lands; the establishment of such a district had the effect of withdrawing all lands within its boundaries “from all [512] forms of entry of settlement.” 16 That section also expressly provided that “Nothing in this Act shall be construed in any way ... to affect any land heretofore or hereafter surveyed [513] which, except for the provisions of this Act, would be a part of any grant to any State. . . Thus, § 1 preserved the original school land grants, whether or not the designated sections had already been identified by survey, but the statute made no provision for school indemnity selections.17
Because the Taylor Grazing Act as originally passed in 1934 applied to less than half of the federal lands in need of more orderly regulation,18 President Roosevelt promptly issued Ex[514] ecutive Order No. 691019 withdrawing all of the unappropriated and unreserved public lands in 12 Western States, including Utah, from “settlement, location, sale or entry” pend[515] ing a determination of the best use of the land. The withdrawal affected the land covered by the Taylor Grazing Act as well as land not covered by the statute. The President’s authority to issue Executive Order No. 6910 was expressly conferred by the Pickett Act.20
[516] Congress responded to Executive Order No. 6910 by amending the Taylor Grazing Act in 1936 in two respects that are relevant to this case. First, it expanded the acreage subject to the Act, see n. 18, supra. Second, it revised § 7 of the Act, see n. 17, supra, to give the Secretary the authority, in his discretion, to classify both lands within grazing districts and lands withdrawn by the recent Executive Order as proper not only for homesteading, but also, for the first time, for satisfaction of any outstanding “lieu” rights, and to open such lands to “selection.” The section, thus amended, provided in pertinent part: 21
“The Secretary of the Interior is authorized, in his dis[517] cretion, to examine and classify any lands withdrawn or reserved by Executive order ... or within a grazing district, which are . . . proper for acquisition in satisfaction of any outstanding lieu, exchange or script rights or land grant, and to open such lands to entry, selection, or location for disposal in accordance with such classification under applicable public-land laws. . . . Such lands shall not he subject to disposition . . . until after the same have been classified. . . .” (Emphasis added.)
The changes in this section were apparently prompted in part by the fact that while the Taylor Grazing Act withdrawal preserved the States’ school grants in place, no provision had been made in the 1934 version for the States’ indemnity selections from land within grazing districts even though the States had expressed the concern that “the establishment of a grazing district would restrict the State in its indemnity selections.” 22 While this omission may not have been critical in 1934 when the Act was passed — since only about half of the unappropriated federal land was then affected — by 1936, as a consequence of Executive Order No. 6910, no land at all was available in the public domain for indemnity selections. It is therefore reasonable to infer that the amendments to § 7 were at least in part a response to the [518] complaint expressed in congressional hearings in 1935, that there was no land available under current law for indemnity-selections.23
[519] The 1936 amendment to § 7 rectified that problem, but did not give the States a completely free choice in making indemnity selections.24 Rather, Congress decided to route the States’ selections through § 7, and thereby to condition their acceptance on the Secretary’s discretion. That decision was consistent with the dominant purpose of both the Act and Executive Order No. 6910 to exert firm control over the Nation’s land resources through the Department of the Interior. In sum, the Taylor Grazing Act, coupled with the withdrawals by Executive Order, “locked up” all of the federal lands in the Western States pending further action by Congress or the President, except as otherwise permitted in the discretion of the Secretary of the Interior for the limited purposes specified in § 7.
This was Congress’ understanding of the Taylor Grazing Act in 1958 when it amended the school land indemnity selection statute to permit selection of mineral lands. Both the House and Senate Reports specifically noted and adopted the Department of the Interior’s assumption “ 'that nothing in this bill is intended to affect the rights or duties of States under other laws’ and, in particular, 'that no change is intended to be made in section 7 of the Taylor Grazing Act, [520] as amended (43 U. S. C., sec. 315f).’ ” H. R. Rep. No. 2347, 85th Cong., 2d Sess., 2 (1958).25 Since Congress was specifically dealing with school indemnity selections, the Reports make it perfectly clear that Congress deemed school indemnity selections to be subject to § 7 of the Taylor Grazing Act. And since the congressional decision in 1958 to allow school land indemnity selections to embrace mineral lands was expressly conditioned on a determination that the lost school lands were also mineral in character, it is manifest that Congress did not intend to grant the States any windfall. It only intended to restore to the States a rough approximation of what was lost. See n. 14, supra.
We therefore hold that the 1936 amendment to the Taylor Grazing Act conferred on the Secretary the authority in his discretion to classify lands within a federal grazing district as proper for school indemnity selection. And we find no merit in the argument that the Secretary’s “grossly disparate value” policy constitutes an abuse of the broad discretion thus conferred. On the contrary, that policy is wholly faithful to Congress’ consistent purpose in providing for indemnity selections, to give the States a rough equivalent of the school land grants in place that were lost through pre-emption or private entry prior to survey. Accordingly, the judgment of the Court of Appeals is reversed.
It is so ordered.
“§ 851. Deficiencies in grants to State by reason of settlements, etc., on designated sections generally
“Where settlements with a view to preemption or homestead have been, or shall hereafter be made, before the survey of the lands in the field, which are found to have been made on sections sixteen or thirty-six, those sections shall be subject to the claims of such settlers; and if such sections or either of them have been or shall be granted, reserved, or pledged for the use of schools or colleges in the State in which they lie, other lands of equal acreage are hereby appropriated and granted, and may be selected, in accordance with the provisions of section 852 of this title, by said State, in lieu of such as may be thus taken by preemption or homestead settlers. And other lands of equal acreage are also hereby appropriated and granted and may be selected, in accordance with the provisions of section 852 of this title, by said State where sections sixteen or thirty-six are, before title could pass to the State, included within any [505] Indian, military, or other reservation, or are, before title could pass to the State, otherwise disposed of by the United States: Provided, That the selection of any lands under this section in lieu of sections granted or reserved to a State shall be a waiver by the State of its right to the granted or reserved sections. And other lands of equal acreage are also appropriated and granted, and may be selected, in accordance with the provisions of section 852 of this title, by said State to compensate deficiencies for school purposes, where sections sixteen or thirty-six are fractional in quantity, or where one or both are wanting by reason of the township being fractional, or from any natural cause whatever. And it shall be the duty of the Secretary of the Interior, without awaiting the extension of the public surveys, to ascertain and determine, by protraction or otherwise, the number of townships that will be included within such Indian, military, or other reservations, and thereupon the State shall be entitled to select indemnity lands to the extent of section for section in lieu of sections therein which have been or shall be granted, reserved, or pledged; but such selections may not be made within the boundaries of said reservation: Provided, however, That nothing in this section contained shall prevent any State from awaiting the extinguishment of any such military, Indian, or other reservation and the restoration of the lands therein embraced to the public domain and then taking the sections sixteen and thirty-six in place therein.” 43 U. S. C. § 851.
“§ 852. Selections to supply deficiencies of school lands
“(a) Restrictions
“The lands appropriated by section 851 of this title shall be selected from any unappropriated, surveyed or unsurveyed public lands within the State where such losses or deficiencies occur subject to the following restrictions:
“(1) No lands mineral in character may be selected by a State except to the extent that the selection is being made as indemnity for mineral lands lost to the State because of appropriation before title could pass to the State;
“(2) No lands on a known geologic structure of a producing oil or gas field may be selected except to the extent that the selection is being made as indemnity for lands on such a structure lost to the State because of appropriation before title could pass to the State; and
“(3) Land subject to a mineral lease or permit may be selected if none of the land subject to that lease or permit is in a producing or producible [506] status, subject, however, to the restrictions and conditions of the preceding and following paragraphs of this subsection.” 43 U. S. C. §852 (a).
Title 43 U. S. C. § 853 provides that in applying this statute to Utah, the words “sections sixteen and thirty-six” also include sections,two and thirty-two.
“WHEREAS, the act of June 28, 1934 (ch. 865, 48 Stat. 1269), provides, among other things, for the prevention of injury to the public grazing lands by overgrazing and soil deterioration; provides for the orderly use, improvement and development of such lands; and provides for the stabilization of the livestock industry dependent upon the public range; and
“WHEREAS, in furtherance of its purposes, said act provides for the creation of grazing districts to include an aggregate area of not more than eighty million acres of vacant, unreserved and unappropriated lands from any part of the public domain of the United States; provides for the exchange of State owned and privately owned lands for unreserved, surveyed public lands of the United States; provides for the sale of isolated or disconnected tracts of the public domain; and provides for the leasing for grazing purposes of isolated or disconnected tracts of vacant, unreserved and unappropriated lands of the public domain; and
“WHEREAS, said act provides that the President of the United States may order that unappropriated public lands be placed under national forest administration, if, in his opinion, the land be best adapted thereto; and
“WHEREAS, said act provides for the use of public land for the conservation or propagation of wild life; and
“WHEREAS, I find and declare that it is necessary to classify all of the vacant, unreserved and unappropriated lands of the public domain within certain States for the purpose of effective administration of the provisions of said act ;
“NOW, THEREFORE, by virtue of and pursuant to the authority vested in me by the act of June 25, 1910 (ch. 421, 36 Stat. 847), as amended by the act of August 24, 1912 (ch. 369, 37 Stat. 497), and subject to the conditions therein expressed, it is ordered that all of the vacant, unreserved, and unappropriated public land in the States of Arizona, [515] California, Colorado, Idaho, Montana, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Utah, and Wyoming be, and it hereby is, temporarily withdrawn from settlement, location, sale or entry, and reserved for classification, and pending determination of the most useful purpose to which such land may be put in consideration of the provisions of said act of June 28, 1934, and for conservation and development of natural resources.
“The withdrawal hereby effected is subject to existing valid rights.
“This order shall continue in full force and effect unless and until revoked by the President or by act of Congress.”
“[T]he President may, at any time in his discretion, temporarily withdraw from settlement, location, sale, or entry any of the public lands of the United States . . . and reserve the same for water-power sites, irrigation, classification of lands, or other public purposes to be specified in the orders of withdrawals, and such withdrawals or reservations shall remain in force until revoked by him or by an Act of Congress.” Ch. 421, 36 Stat. 847.
Although the description of the withdrawal power does not specifically mention state indemnity selections, the power as described is so broad and general that it seems clear that had such an exception been intended, Congress would have made it express.
In Wyoming v. United States, 255 U. S. 489, this Court plainly indicated that an executive withdrawal of federal land under the Pickett Act would defeat a later attempt to select any part of such land as indemnity for lost school sections. The holding in the case was that an indemnity selection’s validity should be tested as of the time made, and that a subsequent Pickett Act withdrawal could not defeat an earlier selection by the State that was otherwise valid. If a Pickett Act withdrawal could not preclude a school land indemnity selection, there would have been no need for the Court to reach the timeliness issue.
The Pickett Act was repealed by the Federal Land Policy and Management Act of 1976, §704 (a), 90 Stat. 2792, but all previous withdrawals [516] under the Pickett Act were expressly preserved unless and until modified. §701 (c), 90 Stat. 2786.
In January 1936, President Roosevelt issued Executive Order No. 7274, which excluded from the operation of Executive Order No. 6910 lands which were then or which were thereafter placed within federal grazing districts. Once land was placed within a grazing district, the purpose of Order No. 6910 was, of course, satisfied.
“The Secretary of the Interior is authorized, in his discretion, to examine and classify any lands withdrawn or reserved by Executive order of November 26, 1934 (numbered 6910), and amendments thereto, and Executive order of February 5, 1935 (numbered 6964), or within a grazing district, which are more valuable or suitable for the production of agricultural crops than for the production of native grasses and forage plants, or more valuable or suitable for any other use than for the use provided for under this subchapter or proper for acquisition in satisfaction of any outstanding lieu, exchange or script rights or land grant, and to open such lands to entry, selection, or location for disposal in accordance with such classification under applicable public-land laws, except that homestead entries shall not be allowed for tracts exceeding three hundred and twenty acres in area. Such lands shall not be subject to disposition, settlement, or occupation until after the same have been classified and opened to entry: Provided, That locations and entries under the mining laws including the Act of February 25, 1920, as amended, may be made upon such withdrawn and reserved areas without regard to classification [517] and without restrictions or limitation by any provision of this subehapter. Where such lands are located within grazing districts reasonable notice shall be given by the Secretary of the Interior to any grazing permittee of such lands. The applicant, after his entry, selection, or location is allowed, shall be entitled to the possession and use of such lands: Provided, That upon the application of any applicant qualified to make entry, selection, or location, under the public-land laws, filed in the land office of the proper district, the Secretary of the Interior shall cause any tract to be classified, and such application, if allowed by the Secretary of the Interior, shall entitle the applicant to a preference right to enter, select, or locate such lands if opened to entry as herein provided.”
“[T]oo much thought in all of the hearings on the act was given to the grazing features, and very little attention was given to the mechanics and as to how it would affect all of the public-land laws that we have been functioning under. The result is that we are now tied up in just one general withdrawal of all public lands, and everything in the public-land structure and in all of the public-land laws and the contractual relations between the Government — and I refer to existing exchange acts and everything — they have all ceased to function.
“There is no land that can be acquired, there is no land that can be filed on for any purpose.
“I think all of you Senators will agree with me that there are other uses of the remaining public lands besides grazing. I term it generally to distinguish it from grazing, the use for industrial purposes; in other words, in Arizona a great many of our town sites or smelter sites and the like; those which have everything to do with industry, the title usually has been acquired by exchange selection, scrip, State selections. . . .
“When this bill was before Congress, I wrote our Senators and a great many of us did from Arizona, that we were all in sympathy with the grazing use, but that our fear was that they would get a little too enthusiastic about it and withdraw everything. In other words, I forecasted what has resulted, and I think in some measure that I was responsible for the 80,000,000-acre limitation that was put in. You remember that, Senator Hayden.
“That was just so that they would have to take the land that was suitable and not include everything. But then there was immediately, when it commenced to be administered, a general withdrawal of all remaining public lands.” Hearing on S. 2539 before the Senate Committee on Public Lands and Surveys, 74th Cong., 1st Sess., 3 (1935).
That it was understood that no land was available for the States' school land indemnity selections was confirmed by Senator Hayden at the same hearings. In response to Mr. Page's observation that there was no land open to entry in Arizona for exercise of railroad-grant exchange rights, the Senator observed: “The same thing would be true of a grant made to a State for university purposes or an indemnity selection.” Id., at 15.
Further, it was the clear position of the Interior Department in 1935 [519] that all of the land withdrawn under President Roosevelt’s Executive Order No. 6910 was unavailable for school land indemnity selections. See State of Arizona, 55 I. D. 249, 253 (1935): “The law provides that indemnity lands may be taken for the school sections lost, but through the withdrawal of all public lands, there is no indemnity land to be obtained.”
