(after stating the facts as above):
Tbe important question involved in this case, and tbe only one we deem of sufficient importance to warrant discussion, is: Did tbe Secretary of tbe Interior, in making tbe order or rule authorizing tbe temporary leasing of tbe lands withdrawn from public entry under tbe provisions of tbe reclamation act, exceed bis authority?
It is strenuously insisted by counsel for defendants that the act neither expressly nor by implication authorizes tbe making of any such rule or order, and that tbe leasing of tbe lands in question was without authority of law and therefore void. That Congress may authorize an executive officer to make rules and regulations for tbe carrying into effect of tbe provisions of a law, tbe enforcement of which devolves upon tbe particular branch of tbe executive department 1 to which such officer belongs, is too well settled to adm-it of serious discussion. (United States v. Eaton, 144 U. S. 677, 12 Sup. Ct. 764, 36 L. Ed. 591; Field v. Clark, 143 U. S. 649, 12 Sup. Ct. 495, 36 L. Ed. 294; Caha v. United States, 152 U. S. 211, 14 Sup. Ct. 513, 38 L. Ed. 415; United States v. Dastervignes [C. C.], 118 Fed. 199; United States v. Shannon [C. C.], 151 Fed. 863; United States v. Domingo [D. C.], 152 Fed. 566; In re Kollock, 165 U. S. 526, 17 Sup. Ct. 444, 41 L. Ed. 813; Dastervignes v. United States, 122 Fed. 30, 58 C. C. A. 346.) The validity of a rule of this kind usually depends upon tbe question as to whether the rule itself is an attempt to create a law, or is only a regulation or means of enforcing a law already in existence. If the rule amounts to nothing more than a regulation, the purport and tendency of which is to carry into full force and effect the provisions 2 of the act to which it refers, it is valid and has the same binding force as the law itself. In the case of Railroad Co. v. Commissioners of Clinton County, 1 Ohio St. 77, the rule is tersely and correctly stated as follows:
*466“The true distinction, therefore, is between the delegation of power to make the law, which necessarily involves a discretion as to what the law shall be, and conferring an authority or discretion as to its execution to be exercised under and in pursuance of the law. The first cannot be done; to the latter no valid objection can be made.”
In tbe case of United States v. Domingo, supra, District Judge Beatty, in the course of a well-considered opinion involving this principle, says:
“The solution of the question must in each case be reached by determining whether the rule is an attempt to create a law, or simply a regulation or means of enforcing a law already enacted. If the former, it is void; if the latter, it is as valid as the law itself.”
So, in Locke’s Appeal, 12 Pa. 491, 13 Am. Rep. 716, it is said:
“The true distinction . . .' is this: The Legislature cannot delegate its power to make a law; but it can make a law to delegate a power to determine some facts or state of things upon which the law makes, or intends to make, its own action depend. To deny this would be to stop the wheels of government. There are many things upon which wise and useful legislation must depend, which cannot be known to the lawmaking power, and therefore be a subject of inquiry and determination outside of the halls of legislation.”
We fully agree witb counsel for defendants that the Secretary of the Interior has no authority under his general power of supervision and control of the public 3 domain to lease any part of it, unless authorized to do so by an act of Congress; but the lands in question are not “public lands” in the sense in which that term is generally used and understood. In the case of United States v. Tygh Valley Land & L. S. Co. (C. C.), 76 Fed. 693, it is held that “there is a clear distinction between public .lands and lands that have been severed from the public domain and reserved from sale or other disposition under general laws. Such reservation severs the land reserved from the mass of public domain and appropriates it to a public use.” *467(See, also, Shannon v. U. S., 160 Fed. 870.) Tbe purpose of tbe act under consideration, as expressed in the first section thereof, is “tbe construction and maintenance of irrigation worts for tbe storage, diversion and development of waters for the reclamation of arid and semiarid lands.” The leasing of tbe lands in question is merely an incident to tbe main object to be accomplished under tbe act. It is a matter of common knowledge that when grazing lands of this character are thrown open to tbe public, and owners of live stock generally are permitted ’to graze their flocks and herds thereon in unlimited numbers without let or hindrance, the lands soon become overstocked,. and conflicting interests of the different flock musters arise, conditions which invariably1 bring about and cause bitterness leading to strife, and some1 times to bloodshed. Besides, the grass and herbage under these conditions are soon eaten off, and the small trees and underbrush trampled down and destroyed, and the efficiency of the soil for retaining moisture from the rain and snow is thereby very materially impaired, and the water supply in the particular section correspondingly decreased. Now, the very purpose of the act — the thing to be accomplished— is the storage, diversion, and development of water. Therefore, under the general power conferred on the Secretary of the Interior by section 10, we think he was not only authorized, but it also became his duty, on the withdrawal of these lands from public entry, “to make such rules and regulations as may be necessary and proper for the purpose of carrying the provisions of this act into full force and effect.” We are clearly of the opinion that the 4 Secretary may, under the general powers conferred on him by section 10, establish rules regulating the use of the lands while not needed for the purpose for which they are reserved, and may limit the number of animals that may be grazed thereon; and that the rule in question was a reasonably proper regulation within the meaning' of that section.
Furthermore, the revenue derived from the leasing of *468these lands goes into tbe reclamation fund provided for in tbe act. Tbis fund, under tbe act, is “reserved, set aside and appropriated as a special fund” to be used for tbe very purpose for wbicb tbe lands are withdrawn from public entry. Therefore, instead of being inconsistent with tbe act, tbe leasing of tbe lands 'and the results produced thereby are in strict conformity with it. Section Y óf tbe same act provides: “That where, in carrying out tbe provisions of tbis act, it becomes necessary to acquire any rights or property tbe Secretary of tbe Interior is hereby authorized to acquire the same for tbe United States by purchase or by condemnation under judicial process, and to pay from tbe reclamation fund tbe sums wbicb may be needed for that purpose.”
• Now, if'the contention of defendants is sound, namely, that there is no. authority for tbe leasing of tbe lands in question, and' that tbe owners of live stock have tbe right to pasture their herds thereon at will, it would necessarily follow that they would have tbe same right to pasture whatever lands tbe government might acquiré by purchase or condemnation proceedings for tbe purpose of “carrying out tbe provisions of tbis act,” until such time as tbe lands are actually used in tbe project contemplated by tbe purchase, and that, too, regardless of tbe injury that might be done the property by tbe pasturing of live stock thereon.' And, as stated by counsel for plaintiffs 'in bis brief: “One could establish a saloon near tbe works and thereby interfere with tbe quiet and orderly conduct of the men employed. And one could depasture tbe lands with sheep and graze amongst tbe tents and quarters of tbe employees and officers and in tbe immediate vicinity of the place where tbe construction is being done, to the annoyance of, and what would be in effect a nuisance to, those engaged in tbe work, and necessitate, even in well-grown meadow land, tbe hauling from long distances of -forage for teams employed at tbe works.” In-other words, tbe right of tbe government to occupy tbe lands until such time as they are actually utilized in tbe project *469for which they are reserved would be subordinate to that of a mere interloper or trespasser. A mere statement of the proposition is all that is necessary to refute and overturn any argument that can be made in favor of it.
Defendants, in support of their contention that the lands in question were a part of the public domain in 190I, and that the Secretary of the Interior had no authority to authorize the leasing of them, invite our attention to that part of section 3 of the reclamation act which provides that the Secretary is authorized “to withdraw from entry, except um-der the homestead laws, any public lands believed to be susceptible of irrigation from said works.” All that can. be claimed for this provision is that parties desiring to homestead lands within the areas Avithdrawn may do so by complying with the terms and conditions in relation to homestead entries provided for in the act. It does not follow, however, that, because a party may make a homestead entry of not less than forty nor more than one hundred and sixty acres within the areas withdrawn as provided in the act, he is entitled to graze live stock upon the balance of the lands, which, the record shows, is over fifty thousand acres. True, the homesteader ini such ease would have absolute dominion over the land within his entry, and no rule or regulation of the Secretary of the Interior for the leasing of lands, or otherwise, would give any other party any right whatever to interfere with the homesteader’s right of possession. However, the rights of the homesteader are not involved in this case, and we have adverted to the question for the purpose only of showing that defendants’ contention on this point is without merit.
The judgment of the court below is affirmed, with costs to respondents.
