Mr. Justice Peckham,

after stating the case, delivered the opinion of the court.

The decision of this case involves the validity of the irrigation act enacted by the legislature of the State of California and set forth in the above statement of facts. The principal act, passed in 1SS7, lias been amended once or twice by subsequent legislation, but in its main features it remains as first enacted. The title of the act indicates its purpose. . It is admitted by all that very large tracts of land in California are in fact “ arid lands,” which require artificial irrigation in order to produce anything of value. There are different degrees, however, in- which irrigation is necessary, from a point where, without its use, the land is absolutely uncultivable, to where, if not irrigated artificially, it may yet produce some return for the labor of the husbandman in the shape of a puny and unreliable crop, but nothing like what it could and would do if water were used upon it. There are again other lands which, if not irrigated, will still produce the ordinary cereal crops to a more or less uncertain extent, but which, if water be used artificially upon them at' appropriate times, are thereby fitted to and will produce much more certain and larger crops than without it, and will- be also rendered capable of producing fruit and grapes of all kinds, of first-rate quality and in very large quantities. What is termed the “arid” belt is said in the Census Bulletin, No. 23, for the census of 1890, to extend from Colorado to the Pacific Ocean, and to include over 600,000,000 acres of land.

Of this enormous total, artificial irrigation has thus far been used only upon about three and a half million acres, of which .slightly over a million acres lie in the State of California. It was stated by counsel that something over thirty irrigation districts had been organized in California under the act in question, and that a total bonded indebtedness of more than $16,000-,000 had been authorized by the various districts under the provisions of the act, and that more than $8,000,000 of the bonds had been sold and the money used for the acquisition of property and water rights and for the construction of works necessary for the irrigation of the lands contained in the various districts.

Whether these statements are perfectly accurate or not is a matter of no great importance, as it has been assumed by all that numbers of districts have been formed under the act and a very large indebtedness already incurred, and that more will be necessary before all the districts will be placed in an efficient working condition. All these moneys, if the act be valid, must eventually be repaid from assessments levied upon the lands embraced within the respective districts, while the annually recurring interest upon these moneys is also to be paid in the same way. Taking the California act as a model, it was also stated and not contradicted that several of the other States which contain portions of the arid belt (seven, or eight of them) had passed irrigation acts, and that proceedings under, them were generally awaiting the result of this litigation. The future prosperity of these States, it was claimed, depended upon the validity of this act as furnishing the only means practicable for obtaining artificial irrigation, without the aid of which millions and millions of acres wuuld be condemned to lie idle and worthless, which otherwise would furnish enormous quantities of agricultural products and increase the material'wealth and prosperity of that whole section of country. On the other hand, it has been asserted, with equal earnestness, that the whole scheme of the act will, if carried out to the end, result in the practical confiscation of lands like those belonging to the appellees herein for the benefit of those owning different kinds of land upon which the assessments for the water would be comparatively light, and the benefits resulting from its use far in excess of those otherwise situated. Such results, it is said, are nothing more than taking by legislation the property of one person or class of persons and giving it to another, which is an arbitrary act of pure spoliation, from which the citizen is protected, if not by any state constitution at least by the Federal instrument, under which we live and the provisions of which we are all bound to obey.

These matters are only alluded to for the purpose of showing the really great practical importance of the question before the court to the people of California, and of those other States where similar statutes have been passed. .Important not alone to the public,’but also and specially important to those landowners whose lands are not only to be irrigated but are also to be assessed for the payment of the cost of the construction of the works necessary for supplying the water.

This court fully appreciates the importance of the question, and its decision has been reached after due reflection upon the subject and after a careful еxamination of the authorities bearing upon it.

The form in which the question comes before the court in this case is by appeal from a decree of the United States Circuit Court for the Southern District of California, perpetually enjoining the collector of the irrigation district from executing a deed conveying the land of the plaintiff, Maria King Bradle}r, under a sale made of such land pursuant to the provisions of the act under consideration. The grounds upon which relief was sought were that the act was in violation of the Federal Constitution and also of the constitution of the State of California. The decree is based upon the sole ground that the act violates the Federal Constitution in that it in substance authorizes the taking of the land of the appellee “ without due process of law.” Coming before the court in this way, we are not confined in our review of the decision of the lower court within the same limits that we would be if the case were here on error from the judgment of a state court.

The jurisdiction of the United States Circuit Court in this case was based upon the fact that the plaintiffs were aliens and subjects of Great Britain, and that court therefore had the same jurisdiction as а state court would have had to try the whole question and to examine and decide not only as to its conformity with the Federal Constitution, but in addition whether the act were a violation of the state constitution, and whether the provisions of the act itself had been complied with. In exercising that jurisdiction it was nevertheless the duty of the trial court to follow and be guided by the decisions of the highest state court upon the construction of the statute, and upon the question whether as construed the statute violated any • provision of the state constitution. The same duty rests upon this court, and it has been- so determined from the earliest period of its history. If the act of the state legislature as construed by its highest court conflicts with the Federal Constitution or with any valid act of Congress, it is the duty of the Circuit Court and of this court to so decide, and to thus enforce the provisions of the Federal Constitution. The following are some of the numerous cases in which this principle has been announced and carried into effect: Shelby v. Guy, 11 Wheat. 361; Nesmith v. Sheldon, 7 How. 812; Van Rensselaer v. Kearney, 11 How. 297; Webster v. Cooper, 14 How. 488; Leffingwell v. Warren, 2 Black, 599; Hagar v. Reclamation District No. 108, 111 U. S. 701, 704; Detroit v. Osborne, 135 U. S. 492.

We should not be justified in holding the act to be in violation of the state constitution in the face of clear and repeated ■ decisions of the highest court of the State to the contrary, under the pretext that we were deciding principles of general constitutional law. If the act violate any .provision, expressed or properly implied, of the Federal Constitution, it is our duty to so declare it; but if it do not, there is no justification for the Federal courts to run counter to the decisions of- the highest state court upon questions involving the construction of state statutes or constitutions, on any alleged ground that such decisions are in conflict with sound principles of general constitutional law. The contrary has not been held in this court by the case of Loan Association v. Topeka, 20 Wall. 655. In that case a statute of Kansas was held invalid because by its provisions the property of the citizen under the guise of taxation would be taken in aid of a private enterprise, which was a perversion of the power of taxation. The case was brought in the United States Circuit Court for the District of Kansas, and was decided by that court in favor of the city. There , had been no decision of the highest state court upon the question whether the act violated the constitution of Kansas, and consequently there was none to be followed by the Federal court upon that question. This court held, that a law taxing the citizen for the use of a private enterprise conducted by other citizens was an unauthorized invasion of private rights. Mr. Justice Miller said that there were such rights in every free government which were beyond the control of the State. The ground of the decision was as stated, that the act took the property of the citizen for a private purpose, although under the forms of taxation. In thus holding, there was no over ruling or refusing to follow the decisions of the highest court of the State respecting the constitution of its own State.

We are, therefore, practically confined in this case to the inquiry whether the act in question, as it has been construed by the state courts, violatós the Federal Constitution.

The assertion that it does is based upon that part of the Fourteenth Amendment to the Constitution, which reads as follows: “Nor shall any State deprive any person of life, liberty or property without due process of law, nor deny to any person within its jurisdiction the equal protection of the laws.”

Referring to the amendment, above quoted, the appellees herein urge several objections to this act. They say, First, that the use for which the water is to be procured is not in any sense a public one, because it is limited to the landowners who may be such at the time when the water is to be apportioned, and the interest of the public is nothing more than that indirect and collateral benefit that it derives from every improvement of a useful character that is made in the State. Second. They assert that under the act in question the- irrigation of lands need not be limited to those which are in fact unproductive, but that by its very terms the act includes all lands which are susceptible of one mode of irrigation from a common source, etc., no matter how fertile or productive they may already be, and it is denied that the furnishing of a fertilizer for lands of individual proprietors which are already productive, in order to make them more, productive, is in any legal sense a public improvement. Third. It is also objected that under the act the landowner has no right to demand and no opportunity is given him for a hearing on the question whether his land is or can be benefited by irrigation as proposed; also, that he has no right to a hearing upon the question whether the statute has been complied with in the preliminaries requisite to the formation of the district. Fourth. That the basis of assessment for the cost of construction is not in accordance with and in proportion to the benefits conferred by the improvement. And, finallj’, that land which cannot, in fact, be benefited may .yet under the act be placed in one of the irrigation districts and assessed upon its value to pay the'cost .of construction of works which benefit others at his expense. These are the main objections urged against the act.

It has often been said to be extremely difficult to give any sufficient definition of what is embraced within the phrase “due process of law,” as used in the constitutional amendment under, discussion. None will be attempted here. It was stated by Mr. Justice Miller, in Davidson v. New Orleans, 96 U. S. 97, 104, that there was “abundant evidence that there exists some strange, misconception of the scope of this provision as found in the Fourteenth Amendment. In fact it would seem from the character of many of the cases before us and the arguments made in’them, that the clause under consideration is looked upon as a means of bringing to the test of the decision of- this court the abstract opinions of every unsuccessful litigant in.a state court of. the justice of the decision against him, and of the merits of the legislation on which such a decision may be founded.” Of course, no such jurisdiction exists or is claimed to exist by the parties here. It is at the same time most difficult to set certain and clear bounds to the right of this court and consequently to its duty to review questions arising under state legislation with reference to this amendment as to due process of law.

It never was intended that the court should, as the effect of the amendment, be transformed into a court of appeal, where all decisions of state courts involving merely questions of general justice and equitable considerations in the taking of property should be submitted to this court for its determination. The.final jurisdiction of the courts of the States would thereby be enormously reduced and a corresponding increase in the jurisdiction of this court would result, and it would be a great misfortune in each case. Mobile County v. Kimball, 102 U. S. 691, 704; Missouri Pacific Railway v. Humes, 115 U. S. 512, 520. We reiterate the statement made in Davidson v. New Orleans, supra, that “ whenever by the laws of the Sta.te or by state authority a tax, assessment, servitude or other burden is imposed upon property for the public use, whether it be for the .whole State or of some more limited portion of the community, and those laws provide for a mode of confirming or contesting the charge thus imposed in the ordinary courts of justice, with such notice to the person or such proсeeding in regard to the property as is appropriate to the nature of the case, the judgment in such proceedings cannot be said, to deprive the owner of his property without due process of law, however obnoxious it may be to other objections.”

Coming to a review of these various objections, we think the first, that the water is not for a public use, is not well founded. The question, what constitutes a public use, has been before the courts ‍​​​​‌‌​​​​​‌‌‌​​​‌​‌​​‌​‌​‌‌​​‌‌‌‌​​‌‌​‌​​‌‌​‌​​‍of many of the States and their decisions have not been harmonious, the inclination of some of these courts being towards a narrower and more limited definition of such use than those of others.

There is no specific prohibition in the Federal Constitution which acts upon the States in regard to their taking private property for any but a public use. The Fifth Amendment which provides, among other things, that such property shall not be taken for public use without just compensation, applies only to the Federal government, as has many times been decided. Spies v. Illinois, 123 U. S. 131; Thoringion v. Montgomery, 147 U. S. 490. In the Fourteenth Amendment the provision regarding the taking of private property is omitte'd, and the prohibition against the State is confined to its depriving any person of life, liberty or prоperty, without due process of law. • It is claimed, however, that the citizen is deprived of his property without due process of law, if it be taken by or under state authority for any other than a public use, either under the guise of taxation or by the assumption of the right of eminent domain. In that way the question whether private property has been taken for any other than a public use becomes material in this court, even where the taking is under the authority of the State instead of the Federal government.

Is this assessment, for the non-payment of which the land of the plaintiff wasp to be sold, levied for a public purpose ? The question has, in substance, been answered in the affirmative by the people of California, and by the legislative and judicial branches of the state government. The people of the State adopted a constitution which contains this provision:

“ Water and Water Rights — Sec. 1. The use of all water now appropriated or that may hereafter be appropriated, for sale, rental or distribution, is hereby declared to be a public use and subject to the regulation and control of the State in the manner to be prescribed by law.” Constitution of California, Art. 14.

The latter part оf § 12 of the act now under consideration, as amended in March, 1891, reads as follows :

“ The use of all water required for the irrigation of the lands of any district formed under the provisions of this act, together ■with the rights of way for canals and ditches, sites for reservoirs, and all other property required in-fully carrying out the provisions of this act, is hereby declared to be a public use, subject to the regulation and control of the State, in the manner prescribed by law.”

The Supreme Court of California has held in a number of cases that the irrigation act is in accordance with the state constitution, and that it does not deprive the lando.wners of any property without due process of law; that the use of the water for irrigating purposes under the provisions of the act is a public use, and the corporations organized by virtue of the act for the purpose of irrigation are public municipal corporations organized for the promotion of the prosperity and welfare of the people. Turlock Irrigation District v. Williams, 76 California, 360; Central Irrigation District v. De Lappe, 79 California, 351; In re Madera Irrigation District, 92 California, 296.

We do not assume that these various statements, constitutional and legislative, together with the decisions of the state court, are conclusive and binding upon this court upon the question as to what is due process of law, and, as incident thereto, what is a. public use. As here presented these are questions which also arise under the Federal Constitution, and we must decide them in accordance with our views of constitutional law.

It is obvious, however, that what is a public use frequently and largely depends upon the facts and circumstances surrounding the particular subject-matter in regard to which the character of the use is questioned.

To provide for the irrigation of lands in States where there is no color of. necessity therefor within any fair meaning of the term, and simply for the purpose of gratifying the taste of the owner, or his desire to enter upon the cultivation of an entirely new kind of crop, not necessary for the purpose of rendering the ordinary cultivation of the land reasonably remunerative, might be regarded by' courts as an improper exercise of legislative will, and the use might not be held to be public in any constitutional sense, no matter how many owners were interested in the scheme. On the other hand, in a State like California, which confessedly embraces millions of acres of arid lands, an act of the legislature providing for their irrigation might well be regarded as an act devoting the water to a public use, and therefore as a valid exercise of the legislative power.. The people of California and the members of her legislature must in the nature of things be more familiar with the facts and circumstances which surround the subject and with the necessities and the occasion for the irrigation of the lands than can any one be who is a stranger to her soil. This knowledge and familiarity must have their due weight with the state courts which are to pass upon the question of public use in the light of the facts which surround the subject in their own State. For these reasons, while not regarding the matter as concluded by these various declarations and acts and decisions of the people and legislature and courts of California, we yet, in the consideration of the subject, accord to and treat them with very great respect, and we regard the decisions as embodying the deliberate judgment and matured thought of the courts of that State on this question.

Viewing the subject for ourselves and in the light of these considerations we have very little difficulty in coming to the same conclusion reached by the courts of California.

The use must be regarded as a public use, or else it would seem to follow that no general scheme of irrigation can be formed or carried into effect. In general, the water to be used must be carried for some distance and over or through private property which cannot be taken in invitum if the use to which it is to- be put be hot public, and if there be no power to take property by condemnation it may be impossible to acquire it at all. The use for which private property is to be taken must be a public one, whether the taking be by the exercise of the right of eminent domain or by that of taxation. Cole v. Le Grange, 113 U. S. 1. A private company or corporation without the power to acquire the land in invitum would be of no real benefit, and at any rate the cost of the undertaking would be so greatly enhanced by the knowledge • that the land must be acquired by purchase, that it would be practically impossible to build the works or obtain the water. Individual enterprise would be equally ineffectual; no one owner would find it possible to construct and maintain water works and canals any better than private corporations or companies, and unless they had the power of eminent domain they could accomplish nothing. If that pоwer could be conferred upon them it could only be upon the ground that the property they took was to be taken for a public purpose.

While the consideration that the work of irrigation must be abandoned if the use of the water may not be held to be or constitute a public use is not to be regarded as conclusive in favor of such use, yet that fact is in this case a most important consideration. Millions of acres of land otherwise cultivable must be left in their present arid and worthless condition, and an effectual obstacle will therefore remain in the way of the advance of a large portion of the State in material wealth and prosperity. To irrigate and thus to bring into possible cultivation these large masses of otherwise worthless lands would seem to be a public purpose and a matter of public interest, not confined to the landowners, or even to any one section of the State. The fact that the use of the water is limited to the landowner is not therefore a fatal objection to this legislation. It is not essential that the entire community or even any considerable portion thereof should directly enjoy or participate in an improvement in order to constitute a public use. All landowners in the district have the right to a proportionate share of the water, and no one landowner is favored above his fellow in his right to the use of the water. It is not necessary, in order that the use should be public, that every resident in the district should have the right to the use of the water. The water is not used for general, domestic or for drinking purposes, and it is plain from the scheme of the act that the water is intended for the use of those who will have occasion to use it on their lands. Nevertheless, if it should so happén that at any particular time the landowner should have more water than he wanted to use on his land, he has the right to sell or assign the surplus or the whole of the water as he may choose.

' The method of the distribution of the water for irrigation purposes, provided for in section 11 of the act, is criticised as amounting to a distribution to individuals and not to lands, and on that account it is claimed that the use for irrigation may not be achieved, and therefore the only purpose which could render the use a public one may not exist. This claim we consider not well founded in the language and true construction of the act. It is plain that some mеthod for apportioning the use of the water to the various lands to bo benefited must be employed, and what better plan than to say that it shall be apportioned ratably to each landowner upon the basis which the last assessment of such owner for district purposes within the district bears to the whole sum assessed upon' the district? Such an apportionment, when followed by the right to assign the whole or any portion of the waters apportioned to the landowner, operates, with as near an approach to justice and equality as can be hoped- for in such matters, and does not alter the use from a public to a private one. This right of assignment may be availed of also by the owner of any' lands which, in his judgment, would not be benefited by irrigation, although the board of supervisors may have otherwise decided. We think it clearly appears that all who by reason of their ownership of or connection with any portion of the lands would have occasion to use the water, would in truth have the opportunity to use it upon the same terms as all others similarly situated. In this way the use, so far as this point is concerned, is public because all persons have the right to use the water under the same circumstances. This is sufficient.

The case does not essentially differ from that of Hagar v. Reclamation District, 111 U. S. 701, where this court held that the power of the legislature of California to prescribe a ■ system for reclaiming swamp lands was not inconsistent with any provision of the Federal Constitution. The power does not rest simply upon the ground that the reclamation must be necessary for the public health. That indeed is one ground for interposition by the State, but not the only one. Statutes authorizing drainage of swamp lands have frequently been upheld independently of any effect upon the public health, as reasonable regulations for the general advantage of those who are treated for this purpose as owners of a common property. Head v. Amoskeag Manufacturing Co., 113 U. S. 9, 22; Wurtz v. Hoagland, 114 U. S. 606, 611; Cooley on Taxation, 617, 2d ed. If it be essential or material for the prosperity of the community, and if the improvement be one in which all the landowners have to a certain extent a common interest, and the improvement cannot be accomplished without the concurrence of all or nearly all of such owners by reason of the peculiar natural condition of the ‍​​​​‌‌​​​​​‌‌‌​​​‌​‌​​‌​‌​‌‌​​‌‌‌‌​​‌‌​‌​​‌‌​‌​​‍tract sought to be-reclaimed, then such reclamation may be made and the land rendered useful to all and at their joint expense. In .such case the absolute right of each individual owner of land must yield to a certain extent or be modified by corresponding rights on the part of other owners for what is declared upon the whole to be for the public benefit.

Irrigation is not so different from the reclamation of swamps as to require the application of other and different principles to the case. The fact that in draining swamp lands it is a necessity to drain the lands of all owners which are similarly situated, goes only to the extent of the peculiarity of situation and the kind of land. Some of the swamp lands may not be nearly so wet and worthless as some others, and yet all may be so situated as to be benefited by the reclamation, and whether it is so situated or not must be a .question of fact. The same reasoning applies to land which is, to some extent, arid instead of wet. Indeed, the general principle that arid lands may be provided with water and the cost thereof provided for by a general tax or by an assessment for local improvement upon the lands, benefited, seems to be admitted by counsel for the appellees. This necessarily assumes the proposition that watеr used for irrigation purposes upon lands-which are actually arid is used for a publio purpose, and the tax to pay for it is collected for a public use, and the assessment upon lands benefited is also levied for a public purpose. Taking all the facts into consideration, as already touched ■ upon, we have no doubt that the irrigation of really arid lands is a public purpose, and the water thus used is put to a public use.

Second. The second objection urged by the appellees .herein is that the operations of this act need not be and are not limited to arid, unproductive lands but include within its possibilities all lands, no matter how fertile or productive, so long as they are susceptible “in their natural state” of one mode of irrigation from a common source, etc. The words “ in their natural state ” are interpolated in the text of the statute, by the counsel for the appellees, on the assumption that the Supreme Court of California has thus construed the act in Modesto Irrigation District v. Tregea, 88 California, 334. The objection had been made in that case that it was unlawful to include the city of Modesto in an irrigation district. The court, per Chief Justice Beatty, said that the legislature undoubtedly intended that cities and towns should in proper cases be included in irrigation districts, and that the act as thus construed did not violate the state constitution. The learned Chief Justice also said :

“ The idea of a city or towm is of course associated with the existence of streets to a greater or less extent, lined with shops and stores, as well as of dwelling-houses, but it is also a notorious fact that in many of the towns and cities of California there are gardens and orchards inside the corporate boundaries, requiring irrigation. It is equally notorious that in many dis tricts lying- outside 'of the corporate limits of any city or town there are not only roads and highways, but dwelling-houses, outhouses, warehouses, and shops. With respect to these things, which determine the usefulness of irrigation, there is only a difference of degree between town and country. . . . It being equally clear and notorious as matter of fact that there are cities and towns which not only maybe benefited by irrigation, but actually have in profitable use extensive systems for irrigating lands within their corporate limits, it cannot be denied that the supervisors of Stanislaus County had the power to determine that the lands comprising the city of Modesto would be benefited by irrigation and might bo inсluded in an irrigation district. . . .

“ In the nature of things, an irrigation district must cover an extensive tract of land, and no matter how purely rural and agricultural the community may be, there must exist here and there within its limits a shop or warehouse covering a limited extent of ground that can derive no direct benefit from the use of water for irrigation. Here, again, the difference between town and country is one of degree onhr, and a decision in the interest of the shop owners in towns, that their lots cannot be included in an irrigation district, would necessarily cover the case of the owner of similar property outside of a town. It is nowhere contended by the appellant that in organizing irrigation districts it is the duty of the supervisors to exclude by demarcation every tract or parcel of land that happens to be covered by a building or other structure which unfits it for cultivation, and certainly the law could not be so construed without disregarding many of its express provisions, and at the same time rendering it practicall\r inoperative. We construe the law to mean that the board may include in the boundaries of the district all lands which in their natural state would he benefited by irrigation and are susceptible of irrigation by one system, regardless of the fact that buildings or other structures may have been erected here and there upon small lots, which are thereby rendered unfit for cultivation at the same time that their value for other purposes may have been greatly enhanced.”

We do not see in this construction, the meaning of which is apparent from the foregoing quotations from the opinion, any substantial difference, favorable to the appellees, from the act without the interpolation of those words.

As an evidence of what can be' done under the act it is alleged in the complaint in this suit that the plaintiff is the owner of forty acres of land in the district, and that it is worth $5000, and that it is subject to beneficial use without the necessity of water for irrigation, and that it has been used beneficially for the past several years for purposes other than cultivation with irrigation. These allegations are admitted by the answer of the, defendants, Who nevertheless assert that if a sufficient supply of water is obtained for the irrigation of the plaintiff’s land, the same can be beneficially used for many purposes other than that for which it can be used without the water for irrigating the same.

What is the limit of the power of the legislature in regard to providing for irrigаtion ? Is it bounded by the absolutely worthless condition of the land without the artificial irrigation? Is it confined to-land which cannot otherwise be made to yield the smallest particle of a return for the labor bestowed upon it? If not absolutely worthless and incapable of growing any valuable thing without the water, how valuable may the land be and to'what beneficial use and to what extent may it be put. before it reaches the point at which the legislature has no power to provide for its improvement by that means ? The general power of the legislature over the subject of providing for the irrigation of certain kinds of lands must be admitted and assumed. The further questions of limitation, as above propounded, are somewhat legislative in their nature, although subject to the scrutiny and judgment of the courts to the extent that it must appear that the use intended is a public use as that expression has been defined relatively to this kind of legislation.

The legislature by this act has not itself named any irrigation district, and, of course, has not decided as to the nature and quality of any specific lands which have been included in any such district. It has given a general statement as to what conditions must exist in order to permit the inclusion оf any land within a district. The land which can properly be so included is, as we think, sufficiently limited in its character by the provisions of the act. It must be susceptible of one mode of irrigation, from a common source and by the same system of tvorks, and it must be of such a character that it will be benefited by irrigation by the system to be adopted. This, as we think, means that the amount of benefit must be substantial and not limited to the creation of an opportunity to thereafter use the land for a new kind of crop, Avhile not substantially benefiting it for the cultivation of the old kind, Avhich it had produced in reasonable quantities and Avith ordinary certainty and success, without the aid of artificial irrigation. The question whether any particular land would be thus benefited is necessarily one of fact.

The legislature not having itself described the district, has not decided that any particular land would or could possibly be benefited as described, and, therefore, it Avould be necessary to give a hearing at some time to those interested upon the question of fact Avhether or not the land of any owner Avhich Avas intended to be included would be benefited by the irrigation proposed. If such a hearing Avere provided for by the act, the decision of the tribunal thereby created Avould be sufficient. Whether it is provided for will be discussed Avhen we come to the question of the proper construction of the act itself. If land Avhich can, to a certain extent, be beneficially used without artificial irrigation, may yet be so much improved by it that it will be thereby and for its original use substantially benefited, and, in addition to the former use, though not in exclusion of it, if it can .then be put to other' and more remunerative uses, we think it erroneous to say that the furnishing of artificial irrigation to that kind of land cannot be, in a legal sense, a public improvement, or the use of the Avater a public use.

Assuming for the purpose of. this objection that the owner of these lands had by the provisions of the act, and before the lands Avere finally included in the district, an opportunity to be heard before a proper tribunal upon the question of bene fits, we are of opinion that the decision of such a tribunal, in the absence of actual fraud and bad faith, would be, so far as this court is concerned, conclusive upon that question. It cannot be that upon a question of fact of such a nature this court has the power to review the decision of the state tribunal which has been pronounced under a statute providing for a hearing upon notice. The erroneous decision of such a question of fact violates no constitutional provision. The Circuit Court in this case has not assumed to undertake any such review of a question of fact.

The difference between this case and the case of Spencer v. Merchant, 125 U. S. 345, is said by counsel for appellees to consist in the fact that in the Spencer case the lands in ques-. tion might have been benefited, while here the additional benefit to land already capable of beneficial use without irrigation is in no legal or proper sense a benefit which can be considered for the purpose of an assessment. ¥e think this alleged difference is not material. It is in each case one of degree only, and the fact of the benefit is by the act to be determined after a hearing by the board of supervisors. In this case the board has necessarily decided that question in favor of the fact of benefits by retaining the lands in the district. Unless this court is prepared to review all questions of fact of this nature decided by a state tribunal, where the claim is made that the judgment was Without any evidence to support it or was against the evidence, then we.must be concluded b.y the judgment on such a question of fact, and treat the legаl question as based upon the facts as found by the state board. Due process, of law is not violated, and the equal protection of the laws is given, when the ordinary course is pursued in such proceedings for the assessment and collection of taxes that has been customarily followed in the. State, and where the party who may subsequently be charged in his property has had a hearing or an opportunity for one provided by the statute. Kelly v. Pittsburg, 104. U. S. 78.

In view of the finding'of the board of supervisors on this question of benefits, assuming that there has been one, this court cannot say as a matter of law that the lands of the plaintiff in this case have not been or cannot be Benefited by this proposed irrigation. There can be no doubt that the board of supervisors (if it have power to hear the question of benefits, as to which something will be said under another head of this discussion) would be a proper and sufficient tribunal to satisfy the constitutional requirement in such case. In speaking of a board of supervisors, Mr. Chief Justice Waite in Spring Valley Water Works Company v. Schottler, 110 U. S. 347, 354, said: “ Like every other tribunal established by the legislature for such a purpose, their duties are judicial in their nature, and they are bound in morals and in law to exercise an honest judgment as tо all matters submitted for their official determination. It is not to be presumed that they will act otherwise than according to this rule.” In that case the board was to fix the price of water, while in this it is to determine the fact of benefits to lands. The principle is the- same in each case.

It may be that the action of the board upon any question of fact as to contents or sufficiency of the petition, or upon any other fact of a jurisdictional nature, is open to review in the state courts. It would seem to bé so held in the Tregea case decided in 1891. 88 California, 334.

If thé state courts would have had the right to review these findings of fact, jurisdictional in their nature, the United States Circuit Court had the same right in this case, but it has not done so, its judgment being based upon the sole ground that the act was a violation of the Fourteenth Amendment of the Federal Constitution. Upon the question of fact as to benefits, decided by the board, it is held in the Tregea case that its decision is conclusive. 88 California, supra. Whether a review is or is not given upon any of these questions of fact (if the tribunal created by the State had power to decide them, and if an opportunity for a hearing ‍​​​​‌‌​​​​​‌‌‌​​​‌​‌​​‌​‌​‌‌​​‌‌‌‌​​‌‌​‌​​‌‌​‌​​‍were given by the act), is a mere -question 6f legislative 'discretion. It is not constitutionally necessary in such cases to give a rehearing or an appеal. Missouri v. Lewis, 101 U. S. 22; Pearson v. Yewdall, 95 U. S. 294.

Yery possibly a decision by the statutory tribunal which in- eluded tracts of land within the district that plainly could not by any fair or proper view of the facts be benefited by irrigation, would be the subject of a review in some form and of a reversal by the courts, on the ground that the decision was based not alone upon no evidence in its favor, but that it was actually opposed to all the evidence and to the plain and uncontradicted facts of common knowledge, and was given in bad faith. In such case the decision would not have been the result of fair or honest, although grossly mistaken judgment, but would be one based upon bad faith and fraud, and so could not be conclusive in the nature of things. A question' of this kind would involve no constitutional element, and its solution would depend upon the ordinary jurisdiction of courts of justice over this class of cases. It is not pretended that such jurisdiction has been invoked or exercised here. As was said by Mr. Justice Miller in Davidson v. New Orleans, supra, where the objection was made that part of the property was not in fact benefited, “ this is a matter of detail with which this court cannot interfere if'it were clearly so; but it is hard to fix a limit within these two parishes where property would not be benefited by the removаl of the swamps and marshes which are within their bounds.”' To the same effect, Spencer v. Merchant, 125 U. S. 345; Lent v. Tillson, 140 U. S. 316, 333.

In regard to the matters thus far discussed, we see no valid objection to the act in question.

Third. We come now to the question of the true construction of the act. Does it provide for a hearing as to whether the petitioners are of the class mentioned and described in the act and as to their compliance with the conditions of the act in regard to the proceedings prior to the presentation of the petition for the formation of the district? Is there any opportunity provided for a hearing upon notice to the landowners interested in the question whether their lands will be benefited by the proposed irrigation ? We think the right to a hearing in regard to all these facts is given by the act, and that it' has been practically so construed by the Supreme Court of California in some of the cases, above cited from the reports of that court and in the cases cited in the briefs of counsel. We should come to the same Conclusion from a perusal of the act. The first two sections provide for’ the petition and a hearing. The petition is to be signed by a majority of the holders of title to lands susceptible of one mode of irrigation, etc. This petition is to be presented to the board of supervisors at a regular meeting, and notice of intended presentation must be published two weeks before the time at which it-is to be presented. The board shall hear the same, shall establish and define the boundaries,- although it cannot modify those described in the petition, so as to except from the district lands susceptible of irrigation by the same system of works applicable to the other lands in' the proposed district, and the board- cannot include in the district, even though included in the description in the petition, lands which shall not, in the judgment of the board, be' benefited by irrigation by said system.

If the board is to hear the petition upon notice, and is not to include land which will not,- in its judgment, be benefited by irrigation by the system, we think it follows as a necessary and a fair implication that the persons interested in or who may be affected by the proposed improvement, have the right under the notice to appear before the board and contest the facts upon which the petition is based, and also the fact of benefit to any particular land included in the description of the proposed district.

It. is not an accurate construction of the statute to say that no opportunity is afforded the landowner to test’ the sufficiency of the petition in regard to the signers thereof and in regard to the other conditions named in the act; nor is it correct to say that the power of the board of supervisors is, in terms, limited to making such changes in the boundaries proposed by the petitioners as it may deem proper, subject to the conditions named in the act.

When the act speaks of a hearing of the petition, what is meant by it ? Certainly it must extend to a hearing of the facts stated in the petition, and whether those who sign it are sufficient in number and are among the class of persons mentioned in the act as alone having the right to sign the same. The obvious purpose of the publication of the notice of the intended presentation of the petition is to give those who are in any way interested in the proceeding an opportunity to appear before the board and be heard upon all .the questions of fact, including the question of benefits- to lands described in the petition. As there is to- be a hearing before the board, and the board-is not to include any lands which in its judgment will .nоt be benefited, the plain construction of the act is that the hearing before the board includes the question as to the benefits of the lands, because that is one of the conditions upon which the final determination of the board is based, and the act cannot in reason be so construed as to provide that while the board is to give a hearing on the petition it must nevertheless decide in favor of the petitioners, and must establish and define the boundaries of the district, although the signers may not be fifty, or a majority of the holders of title, as provided by the act, and notwithstanding some other defect may become apparent upon the hearing.

This provision that the board “shall establish and define such boundaries” (section 2) cannot reasonably-or properly be held to mean that the boundaries must be established notwithstanding any or all of the defects above-mentioned have been proved upon the hearing. The language of the sections taken together plainly implies that the board is to establish and define the boundaries only in case the necessary facts appear upon the hearing which the act provides for.

. It cannot be supposed that the act, whilе providing for a hearing of the petition, yet, at the same time, commands the establishment and defining of the boundaries of a district, notwithstanding the fact that the hearing shows a failure on the part of the petitioners to coinply with some or all of the conditions upon which the right to organize is placed by the same act.

Such an absurdity cannot be imputed to the legislature. It cannot be doubted that, by the true construction of the act, the board of supervisors is not only entitled, but it is its duty, to entertain a contest by a landowner in respect to the question whether the signers of the petition fulfil the requirements described 'in the first section of the act, and if the board find in favor of the contestant upon that issue, it is the duty of the board, under the provisions of the statute, to deny the petition and dismiss the proceedings. Otherwise, what is the hearing for? And if upon a hearing of the question of benefits to any land described' in the' petition it appears to the board that such lands will not be benefited, it is the duty of the board to so decide, and to exclude the lands from the district. The inclusion of any lands is, therefore, in and of itself a determination (after an opportunity for a hearing) that they will be benefited by the proposed irrigation.

Ve have said that the Supreme Court of California has substantially decided these questions in the same way. This appears, among others, in the case of the Modesto Irrigation District v. Tregea, above referred to. The court uses this language in that case :

“ The formation .of irrigation districts is accomplished by proceedings so closely analogous to those prescribed for the formation of swamp-land reclamation districts that the decisions with respect to the latter are authority as to the former, and we cite as conclusive on this point People v. Hagar, 52 California, 181; S. C. 66 California, 60. Many decisions to the same effect are cited in the briefs of counsel, but we deem it unnecessary to refer to them here.”

In the case of People v. Hagar, 52 California, 171, 182, it was held that the board of supervisors, on presentation of the petition, .was to hear and determine the question of jurisdiction, and whether the allegations of the petition were true. An approval and confirmation of the petition and the establishment of the district was held to be a conclusive judgment by the board that the lands mentioned' and in question were swamp lands; that the petitioners held the proper evidences of title thereto, and that the lands would' be benefited by the reclamation. These jurisdictional facts, it was held, must exist befоre the district could lawfully be established.

The provision for a hearing in the irrigation act is similar, and the condition therein that lands which in the judgment of' the board are not benefited shall not be included, renders the determination of the board including them after a hearing a judgment that such lands will be benefited by the proposed plan of irrigation.

The publication of a notice of the proposed presentation of the petition is a sufficient notification to those interested in the question and gives them an opportunity to be heard before the board. Hagar v. Reclamation District, 111 U. S. 701; Lent v. Tillson, 140 U. S. 316 ; Paulsen v. Portland, 149 U. S. 30.

The formation of one of these irrigation districts amounts to the creation of a public corporation, ‍​​​​‌‌​​​​​‌‌‌​​​‌​‌​​‌​‌​‌‌​​‌‌‌‌​​‌‌​‌​​‌‌​‌​​‍and their officers are public ■officers. This has been held in the Supreme Court of California. In re Madera Irrigation District, 92 California, 296; People v. Selma District, 98 California, 206.

There is nothing in the essential nature of such a corporation, so far as its creation only is concerned, which requires notice to.or hearing of the parties included therein before it can be formed. It is created-for a public purpose, and it rests in the discretion of the legislature when to create it, and with what powers to endow it.

In the act under consideration, however, the establishment of its boundaries and the purposes for which the district is created, if it be finally organized by reason of the approving vote of the people, will almost necessarily be followed by arid result in an assessment upon all the lands included within the boundaries of the district. The legislature thus in substance provides for the creation not alone of a public corporation, but of a taxing district whose boundaries are fixed, not by the legislature, but, after a hearing, by the board of supervisors, subject to the final approval by the people in an election called for that purpose. It has been, held in this court that the legislature has power to fix such a district for itself without any hearing as to benefits, for the purpose of assessing upon the lands within the district the cost of a local, public improvement.’ The legislature, when it fixes the district itself, is supposed to have made proper inquiry, and to have finally and conclusively determined the fact of benefits to the land included in the district, and the citizen has no con stitutional right to any other or further hearing upon that question. The right which he thereafter has is to a hearing upon the question of what is termed the apportionment of the tax, i.e., the amount of the tax which he is to pay. Paulsen v. Portland, 149 U. S. 30, 41. But when as in this case the determination of the question of what lands shall be included in the district is only to be decided after a decision as to what lands described in the petition will be benefited, and the decision of that question is submitted to some tribunal (the board of supervisors in this case), the parties wrhose lands are thus included in the petition are entitled to a hearing upon the question of benefits, and to have the lands excluded if the judgment of the board be against their being benefited. Unless the legislature decide the question of benefits itself, the landowner has the right to be heard upon that question before his property can be taken. This, in substance, was determined by the decisions of this court in Spencer v. Merchant, 125 U. S. 345, 356, and Walston v. Nevin, 128 U. S. 578. Such a hearing upon notice is duly provided for in the act.

Then, as to a hearing upon the question of apportionment, the act, in sections 18, 20 and 21, provides a general scheme for the assessment upon the property included in the district, and it also provides for a notice by publication of the making of such assessment, and an opportunity is given to the taxpayer to be heard upon the question of the valuation and assessment, and to make such objections thereto as he may think proper, and after that the assessors are to decidе:

Thus the act provides for a hearing of the landowner both as to the question whether his land will be benefited by the proposed irrigation, and when that has been decided in favor of the benefit, then upon the question of the valuation and assessment of and upon his land included in the district. As to other matters, the district can be created without notice to any one. Our conclusion is that the act, as construed, with reference to the objections considered under this third head, is unassailable.

Fourth. The fourth objection and also the objection above alluded to as the final one, may be discussed together, as they practically cover the same principle. It is insisted that the basis of the assessment upon the lands benefited, for the cost of the construction of the works, is not in .accordance with and in proportion to the benefits conferred by the improvement, and, therefore, there is a violation of the constitutional amendment referred to, and a taking of the property of the citizen without due process of law.

Although there is a marked distinction between an assessment for a local improvement and the levy of a general tax, yet the former is still the exercise оf the same power as the latter, both having their source in the sovereign power of taxation. Whatever objections may be urged to this kind of an assessment, as being in violation of the state constitution, yet as the state court has held them to be without force,we .follow its judgment in that case, and our attention must be directed to the question whether any violation of the Federal Constitution is shown in such an assessment. Can an ad valorem assessment on the land benefited, or, in other words, can such an assessment as is provided for in sections 18, 20, 21 and 22 of the act. be legally levied in such a case as this? Assume that the only theory of these assessments for local improvements upon which they can stand is that they are imposed on account of the benefits received, and that no land ought in justice to- be assessed for a greater sum than the benefits- received by it, yet it is plain that the fact of the amount of benefits is not susceptible of that accurate determination which appertains to a demonstration in geometry. Some means of arriving at this- amount must be used, and the same method may be more or less accurate in different cases involving different facts. Some choice is to be made, and where the fact of some benefit accruing to all the lands has been legally found, can it be that the adoption of an ad valorem method of assessing the lands is to be held a violation of the Federal Constitution ? It seems to us clearly not. It is one of those matters of detail in arriving at the proper and fair amount and proportion of the tax that is to be levied on the land with regard to the benefits it has received, which is open to the discretion of the state legislature, and with which this court ought to have nothing to do. The way of arriving at the amount may be in some instances inequitable and unequal, but that is far from rising to the level of a constitutional problem and far from- a case of taking property without due process of law.

In the case of Davidson v. New Orleans, supra, the assessment, with which this court refused to interfere, was for a local improvement (reclaiming swamp lands), and by § 8 of the act of the legislature of Louisiana, passed in 1858, Laws of Louisiana, 1858, 114, such an uniform assessment was levied upon “ the superficial or square foot of lands situate within the draining section or district of such board as would pay for the cost, of- construction. The effect of this provision was that each foot of land in the whole district.paid the same sum аs any other foot, although the assessment was founded upon the theory of an assessment for benefits. It was complained that the amount assessed upon plaintiff’s lands was excessive, and that part of them received no benefit at all, and it was to that argument that the reply was made that it was a matter of detail so far as this court was concerned, i.e., it was not a constitutional question, and therefore was not reviewable here. 96 U. S. at page 106.

■ In Walston v. Nevin, 128 U. S. 578, an assessment was laid upon lands for benefits received from construction of a local improvement, according to the number of square feet owned by the landowner. It was urged that it was not an assessment governed by the amount of benefits received, but was an absolutely arbitrary and illegal method of assessment. This court held the objection not well founded and that the matter was for the decision of the legislature, to which body the discretion was committed of providing for payment of the improvement.

¥e refer to the case of Cleveland v. Tripp, 13 R. I. 59, decided in 1880, as one which treats this subject with much ability. The act provided for the.construction of a sewer in the city of Providence and directed the laying of an assessment upon the abutting lands of a certain sum for each front foot and another sum for each square foot extending back 150 feet. The claim was made that Such a mode of assessment did not apply the tax in proportion to the benefits received, and was unequal and unfair, and therefore unconstitutional. The court, while admitting the complaints of inequality to be well founded, yet held the act to be within the power of the legislature.

There aré some States where assessments under such circumstances as here exist and made upon an ad valorem basis have been held invalid, as an infringement of some provision of the state constitution, or in violation of the act under which they were levied. Counsel have cited several such in the briefs herein filed. We do .not discover, and our attention has not been called to any case in this court where such an assessment has been held to violate any provision of the Federal Constitution. If it do not, this court can grant no relief.

The method of assessment here provided for may not be the best which could have been adopted in order to accomplish the most equal and exact justice which the nature of the case permits. But none the less we are unable to say that it runs counter to any provision of the Federal Constitution, and we must for that reason hold the objection here considered to bo untenable.

An objection is also urged that it is delegating to others a legislative right, that of the incorporating of public corporations, inasmuch as the act vests in the supervisors and the people the right to say whether such a corporation shall be created, and it is said that the legislature cannot so delegate its power, and that any act performed by such a corporation by means of which the property of the citizen is taken from him, either by the right of eminent domain or by assessment, results in taking such property, without due process of law.

We do not think there is any validity to the argument. The . legislature delegates no power. It enacts conditions upon the performance of which the corporation shall be regarded as organized with the powers mentioned and described in the act:

After careful scrutiny of the objections to this act we are compelled to the conclusion that ‍​​​​‌‌​​​​​‌‌‌​​​‌​‌​​‌​‌​‌‌​​‌‌‌‌​​‌‌​‌​​‌‌​‌​​‍none of such objections is well taken. The judgment appealed from herein is therefore

Reversed and the cause remanded to the Circuit Court of the United States for the Southern District of California for further proceedings not inconsistent with this opinion.

Mr. Chief Justice Fuller and Mr. Justice Field dissented.
