delivered the opinion of the court.
This is a suit by the United States to quiet the title to section 32 of a designated township in Carbon County, Utah, the suit being specially directed against a claim asserted by the defendant, as an assignee of the State, under 'the school land grant to the latter. Whether this tract passed to the State .under that grant or was reserved to the United States as mineral land is the matter in controversy. In the District Court the United States prevailed as to all but 40 acres, but in the Circuit Court of Appeals that decree was reversed and one for the defendant was directed. 228 Fed. Rep. 421.
The evidence shows that the entire section, excepting 40 acres, is valuable for coal and has been known to be so since before Utah became a State. Land valuable for coal is mineral land within the meaning-of the public land laws. Thus the ultimate question for decision is whether the school land grant to Utah embraces mineral land. The grant is found in § 6 of the Act of Congress of July .16, 1894, c. 138, 28 Stat. 107, and is copied in the margin 1 *567 with another closely related section of the same act. It neither expressly includes mineral lands nor expressly excludes them. If it did either, it would be conclusive of the will of Congress upon the point. But, as it makes no mention of such lands, it is permissible — indeed, is essential — to inquire whether the congressional will is otherwise made manifest, that is to say, whether the general words of the grant are to be read in the light of other statutes and a settled public policy in respect of mineral lands.
In the legislation concerning the public lands it has been the practice of Congress to make a distinction between mineral lands and other lands, to deal with them along different lines, and to withhold mineral lands, from disposal save under laws specially including them. This practice began with the ordinance of May 20, 1785, 10 Journals of Congress, Folwell’s ed., 118, and was observed

with such persistency in the early land laws

United States
v.
Gratiot,
While the early land laws occasionally and specially provided for the sale of mineral lands, they very generally evinced a purpose to reserve such lands for future disposal; and this purpose was given particular emphasis following the discovery of gold in California in 1848, as is shown in the Oregon donation act, the homestead act (which *569 adopted the mineral land reservation of the preemption act of 1841), the grant to the several States for the benefit of agricultural colleges, the railroad land grants and other land acts of that period. 1 Noticeable among those acts is one which, in dealing with grants to Nevada and surveys in that State, declared, “in all cases lands valuable for mines of gold, silver, quicksilver, or copper shall be reserved from sale,” c. 166, 14 Stat. 85, and another declaring, "no act passed at the first session of the thirty-eighth congress, granting lands to states or corporations, to aid in the construction of roads or for other purposes, or to extend the time of grants heretofore made, shall be so construed as to embrace mineral lands, which in all cases shall be, and are, reserved exclusively to the United States, unless otherwise specially provided in the act or acts making the grant.” 13 Stat. 567. Although applied in one instance to lands in Nevada and in the other to grants made at a particular session of Congress, these declarations were but expressive of the will of Congress that every grant of public lands, whether to a State or otherwise, should be taken as reserving and excluding mineral lands in the absence of an expressed purpose to include them; and upon this theory both declarations were carried into the Revised Statutes as being general and per *570 manent in their nature — the first in enlarged terms as § 2318, 1 and the other as § 2346.
By the Act of March 3, 1853, c. 145, 10 Stat. 244, Congress granted to the State of California sections 16 and 36 in each township for school purposes and large quantities of lands for other purposes. Mineral lands were neither expressly excepted from nor expressly included in the grant of the school sections, but were specially excepted from, the other grants. This difference led to a controversy over the true meaning of the school grant, the state authorities taking the view that it did, and the land officers of the United States that it did not, include mineral lands. Ultimately the controversy came before this court in
Mining Co.
v.
Consolidated Mining Co.,
“Taking into consideration what is well known to have been the hesitation and difficulty in the minds of Congressmen in dealing with these mineral lands, the manner in which the question was suddenly forced upon them, the uniform reservation of them from survey, from sale, from preemption, and above all from grants, whether for railroads, public buildings, or other purposes, and looking to the fact that from all the grants made in this act they are reserved, one of which is for school purposes besides the sixteenth and thirty-sixth sections, we are forced to the conclusion that Congress did not intend to depart from its uniform policy in this, respect in the grant of those sections to the State.
“It follows from the finding of the court and the undisputed facts of the case, that the land in controversy being mineral land, and well known to be so when the surveys of it were made, did not pass to the State under the school-section grant.”
*571
That ruling was reaffirmed and followed in
Mullan
v.
United States,
The conditions ensuing from the discovery of gold and other minerals in the western States and Territories resulted in a general demand for a system of laws expressly opening the mineral lands to exploration, occupation and acquisition, and Congress, responding to this demand, adopted from 1864 to 1873 a series of acts dealing with practically every, phase of the subject and covering all classes of mineral lands, including coal lands.
1
These acts, with some before noticed, were carried into a chapter of the Revised Statutes entitled “Minerals Lands and Mining Resources.” Taken collectively they constitute a special code upon that subject and show that they are intended not only to establish a particular mode of disposing of mineral lands, but also to .except and reserve them from all other grants and modes of disposal where there is no express provision for their inclusion. Thus the policy of disposing of mineral lands only under laws specially including them became even more firmly established than before, and this is recognized in our decisions.

Another statute indicative of the policy of Congress and pertinent to the present inquiry is the Act of February 28, 1891, c. 384, 26 Stat. 796, which defines the indemnity to which a State or Territory is entitled in respect of its school grant. In addition to dealing with deficiencies occurring in other ways, it provides, "And other lands of equal acreage are also hereby Appropriated and granted, and may be selected by said State or Territory where sections sixteen or thirty-six are mineral land.” In this there is a plain implication that where those sections are mineral-known to be so when the grant takes effect — they do not pass under the grant. And it does not militate against this implication that under another, provision the State may surrender those sections and take.other lands in lieu of them where, although not known to be mineral when the grant takes effect, they are afterwards discovered to be so. See
California
v.
Deseret Water &c.
Co.
What has been said demonstrates that the school grant to Utah must be read in the light of the mining laws, the school land indemnity law and the settled public policy respecting mineral lands, and not as though it constituted the sole evidence of the legislative will.
United States
v.
Barnes,
This conclusion is fortified by other considerations. When the grant was made Utah was known to be rich in minerals and salines. Besides this grant the act contains others aggregating 1,570,080 acres. In none is there any mention of mineral lands. As to 110,000 acres there is an express- inclusion of saline lands. This silence as to mineral lands, when contrasted with the special inclusion of saline lands, indicates that the former are not included. See
Montello Salt Co.

v.
Roberts,
It results that the decree of the Circuit Court of Appeals'must be reversed and that of the District Court affirmed.
It is so ordered.
Notes
Sec. 6. That upon the admission of said State into the Union, sections numbered two, sixteen, thirty-two, and thirty-six in every town *567 ship of said proposed State, and where such sections or any parts thereof have been sold or otherwise disposed of by or under the authority of any Act of Congress other lands equivalent thereto, in legal subdivisions of not less than one quarter section and as contiguous as may be to the section in lieu of which the same is taken, are hereby granted to said State for the support of common schools, such indemnity lands to be selected within said State in such manner as the legislature may provide, with the approval of the Secretary of the Interior: Provided, That the second, sixteenth, thirty-second, and thirty-sixth sections embraced in permanent reservations for national purposes shall not, at any time, be subject to the grants nor to the indemnity provisions of this Act, nor shall any lands embraced in Indian, military, or other reservations of any character be subject to the grants or to the indemnity provisions of this Act until the reservation shall have been extinguished and such lands be restored to and become a part of the public domain.
