(after stating the facts as above.) It has been so often decided that the grant to the railroad company under this, and similar acts, is a grant in prsesenti, passing and vefeting a present title, only to be defeated by a failure to perform the conditions subsequent, and suitable judicial proceedings on the part of the United States, to forfeit them, that it is only necessary to cite the authorities without further discussing the question. Railroad Co. v. Railroad Co., 97 U. S. 496; Schulenberg v. Harriman, 21 Wall. 44; Van Wych v. Knevals, 106 U. S. 360, 1 Sup. Ct. Rep. 336. “‘There be and is hereby granted’ are words of absolute donation, and import a grant in prsesenti. This court has held that they can have no other meaning.” Railroad Co. v. U. S., 92 U. S. 741; Wright v. Roseberry, 121 U. S. 500, 7 Sup. Ct. Rep. 985; Railroad Co. v. Orton, and cases cited, 6 Sawy. 198; Mr. Justice Field went over the subj ect fully in Denny v. Dodson, 13 Sawy., 32, Fed. Rep. 899, in which he held that not merely the equitable title, but the legal title to the land passed by the legislative grant in prsesenti, in such sense that an action of ejectment could be maintained upon it — that the patent provided for, was not necessary to pass the title, but was only a convenient instrument of evidence, citing a passage from the opinion of the supreme court, in Langdeau v. Hanes, 21 Wall. 521, as follows:
“In the legislation of congress a patent has a double operation. It is a conveyance by the government, when the government has any interest to convey, but, where it is issued upon the continuation of a claim of a previously existing title, it is documentary evidence, having the dignity of a record, of the existence of that title, or of such equities respecting the claim, as justify its recognition, and confirmation. The instrument is not the less efficacious as evidence of previously existing rights because it also embodies words of release or transfer from the government.” Denny v. Dodson, 32 Fed. Rep. 904.
The provision of section 21 of the act of 1864 requiring the railroad company to pay the expenses of surveys and conveyance, does not affect the question of the vesting of the title under the legislative grant. It only applies to the issue of a convenient instrument of evidence. But in this case the title had already vested and passed beyond the authority of congress, before the passage of the act of 1864, which could only amend the prior act so far as to effect its future operation as a law.
A title, therefore, vested by the grant, and performance of the conditions, upon which an action of ejectment can be maintained.
The next question is, did the land in question pass, by the grant of 1862 perfected in 1866-67 in which a gold mine was discovered in 1883, 21 years after the grant attached by the filing of a plat of the general route of the railroad, and the withdrawal of the lands in pursuance of the statute, by the secretary of the interior, and more than 17 years after the completion of the road, and its acceptance by the president., and more than 16 years after the final survey, and report of the lands, as agricultural, and not mineral? The parties to this grant, both the,United States, and the grantee, must be presumed to have contemplated a gr&nt *621in view of tbe condition of the lands as they were known, or appeared to be, at the time the grant took effect. In the exception of “mineral lands” from the grant, congress must have meant not only lands mineral, iu fact, but, lands known to be mineral, or, at most, such as were, apparently. mineral, and, generally, recognized as such. Congress could not have contemplated that the discovery of a paying mine, 15 or 20 years after the making of the grant, and the performance of all the conditions by the grantee, required to perfect the title, and render it irrevocable, should vitiate the grant. If so, then such a discovery 50, or 100 years after, would effect the same result. In granting the public lands, congress must be presumed to deal with them in view of the conditions as they are known, or supposed to be, at the time. Exceptions must be presumed to refer to- matters that are readily apparent upon inspection. Any others would be altogether too indefinite to be valid. The conditions constituting the exception ought, certainly, to be ascertainable at the time the grant takes effect, or they ought not to be operative; otherwise the greatest confusion and inconvenience, public and private, must, necessarily, result.
The grant should point out what is granted, in such certain terms, that the grantee may be able to ascertain by inspection and know at the time the location is definitely fixed, and it becomes operative, what specific tracts of land are granted, and what are excepted from the grant. These lands soon after the grant, were conveyed, in trust, under aulhorRy of the law, as security for the bonds issued, out of the proceeds of which, the road was constructed; and the proceeds of these sales are devoted by the trustees to the redemption of the bonds. Is this security to be impaired, or destroyed, by taking from the operation of the grant all lands in which at any future time gold or other valuable metals may he discovered? If so, all of the lands may sooner or later revert to the United States, and these bondholders, and those who, in good faith have purchased the lands of the company without being aware of the mines secluded in their lower depths, will be largely injured.
These words “mineral lands,” used in the act, must be construed in a practical sense — as practical men would use them in contracting about them' — must be construed with reference to their present known, or at least, obviously apparent condition.
I had occasion to express my views in a general way upon this subject in Cowell v. Lammers, 10 Sawy. 246, 21 Fed. Rep. 206. In that case it is said, “by the words ‘mineral lands’ must be understood lands known to be such, or which there is a satisfactory .reason to believe are such, at the time of the grant, or patent.” I'll that case, it was not necessary to go behind the date of the patent, which was issued to the company in accordance with, and in pursuance of the grant, and not to a trespasser in opposition to the grant, as in this instance. Those who make or take subsequent grants must see that there is something to grant. It is not enough to know, that the lands contain minerals, at the date of the issue of the patent, in order to grant them as mineral lands. It must be known, also, that there has been no prior divestment of title. I am satisfied that the *622lands ought not, only, to be mineral, in fact, but, also, to be known as mineral, or there should be satisfactory reason to believe them to be such, at the date when the grant takes effect, in order to fall -within the exception of mineral lands, in such sense, as to defeat the grant. And this is, evidently, the view of the supreme court, as there is no case, so far as I am aware, wherein, that court has sustained an exception, of “mineral lands,” in these grants unless they were known to be mineral, at the time of the grant. This point is very fully considered by the court in Coal Co. v. U. S., 123 U. S. 326, 327, 8 Sup. Ct. Kep. 131. Says the court in that case, quoting from a prior decision:
“ We say ‘ land known at the time, to be valuable for its minerals,’ as there are vast tracts of public land in which minerals of different kinds are found, but not in such quantity as to justify expenditures in the effort to extract them. It is not to such lands, that the term ‘ mineral,’ in the sense of the statute is applicable. We, also, say lands known at the time of their sale to be thus valuable, in order to avoid any possible conclusion against the validity of titles which may be issued for other kinds of land in which years aft-erwards rich deposits of mineral may be discovered. It is quite possible that lands settled upon, as suitable, only, for agricultural purposes, entered by the settler, and patented by the government, under the pre-emption laws, maybe found years after the patent has been issued, to contain valuable minerals. Indeed this has, often, happened. We, therefore, use the term ‘ known to be valuable at the time of sale ’ to prevent any doubt being east upon titles to lands afterwards found to be different in their mineral character from what was supposed when the entrij of them was made and the patent issued. ” 123 TJ. S. 327, 8 Sup. Ct. Kep. 141.
This tvas but affirming similar views before expressed in Deffeback v. Hawke, 115 U. S. 404, 6 Sup. Ct. Rep. 95. In this-case, the supreme court also affirm the view'of the circuit court expressed in Cowell v. Lammers, supra, that an exception inserted in a patent, in express terms, by the secretary of the interior, not required or authorized by the statutes, is void.
Now in this case, according to the allegations of the complaint, after the grant had been made, and all the conditions fully performed by the grantee, the road accejated by the president, and the title irrevocably vested in the grantee, and, before there was any authority at all to survey mineral lands, as in the case of Cowell v. Lammers, the towmship and section including the lands in question, were surveyed, as agricultural lands, and so returned and represented to the land-office; and they were so regarded until the discovery of gold-bearing quartz, many years afterward, in 1883, when a patent was refused the railroad company, aud issued to defendant’s grantor. This discovery, in our judgment, was too late. There was at the date of the legislative grant, and for many years afterwards, nothing appearing in the nature of a valid exception to take the premises in controversy out of the operation of the grant. The department, in issuing the patent to defendant’s grantor, instead of to the railroad company, seems to have acted in view' of the condition of things, as they appeared, after the discovery of the gold-bearing quartz, in 1888, and not as they appeared, and were known, at the time of the making *623of the congressional grant; the performance of the conditions of the grant by the grantee; and the subsequent survey made by the government in 1866-67, as agricultural lands.
It is further objected, that the patent thus issued to defendant’s grantor, cannot be, collaterally, attacked, in an action of ejectment — that it can only be impeached by a direct proceeding in equity to declare it void, or control whatever title passed by it for the benefit of the party equitably entitled. This, it appears to us, would have been the better course, and at first we were disposed to think it was the only course. But upon further consideration, and an examination of the authorities, we think the case does not fall withiu that rule. In recognizing the rule insisted upon in a proper case, the supreme court, in Smelting Co. v. Kemp, 104 U. S. 641, add:
“Of course, when we speak of the conclusive presumptions attending a patent for lands, we assume that it was issued in a case where the department had jurisdiction to act and execute it; that is to say, in a case where the lands belonged to the United ¡States, and provision liad been made by law for their sale. If they never were pubiie property, or had previously been disposed of, or if congress had made no provision for their sale, or had reserved them, the department 'would have no jurisdiction to transfer them, and its attempted conveyance of them would be inoperative and void, no matter with what seeming regularity the forms of law may have been observed. The action of the department would in that event be like that of any other special tribunal not having jurisdiction of a case which it had assumed to decide. Matters of this kind, disclosing a want of jurisdiction, may be considered by a court of law. In such cases the objection to the patent reaches beyond the action of the special tribunal, and goes to the existence of a subject upon which it was competent to act.”
And in Wright v. Roseberry, 121 U. S. 519, 7 Sup. Ct. Rep. 985, the supreme court quote, and approve the foregoing, and further quote and approve another passage, as follows:
“A patent may be collaterally impeached in any action, and its operation as a conveyance defeated, by showing that the department had no jurisdiction to dispose of the lands; that is, that the law did not provide for selling them, or that they had been reserved from sale, or dedicated to special purposes, or had been previously transferred to others. In establishing any of these particulars, the judgment of the department upon matters properly before it is not assailed, nor is the regularity of its proceedings called into question; but its authority to act at all is denied, and shown never to have existed.”
They cite other authorities to sustain this view. Now those observations cover the case. The point was, also, directly decided in Doolan v. Carr, 125 U. S. 618, 8 Sup. Ct. Rep. 1228. These lands under the allegations of the complaint, “had previously been disposed of” by legislative grant, and the United States bad no interest left to grant. There was no jurisdiction left to dispose of them to somebody else as there was nothing to dispose of. And the court says:
“A patent may be collaterally impeached in any action, and its operation as a conveyance defeated, by showing that the department had no jurisdio*624tion to dispose of the lands, * * ⅜ or that they had been previously' transferred to others.”
That is this case. Had the department issued a prior patent to the railroad company, and then one to the defendant’s grantor, there can be no doubt that it would be the duty of the court in this case to determine which carried the title. If the first patent was valid, there would be nothing upon which the second could operate. So in this case, if the congressional grant was valid, and operative, there was nothing upon w'hich the patent to the defendant’s grantor could operate, and it is com- . petent for the court in this case to ascertain which grant took the land.
Upon the views expressed, the demurrer must be overruled, and it is so ordered, upon the usual terms.
