Opinion of the court by

The questions to be determined in the case are, (a,) whether the city of Oklahoma City had the power to contract for the construction of sewers, or whether its power for the execution of that work was confined to the employment of servants and agents working for wages; (b,) whether the special assessments against abutting lots for the cost of local improvements were or were not “taxes,” under the meaning of the organic act of the territory, which provides that “all property subject to taxation shall be taxed in proportion to its value;” (c,) whether, under the statute providing for the construction of lateral sewers, the cost of such construction should be apportioned equally among all the lots in a certain district, or whether the special assessment should be so apportioned that each particular lot should be assessed only with that portion of the total cost of the sewer which had been incurred in constructing the lateral sewer along and in front of the particular lot assessed; (d,) whether the plaintiffs in this case, by wait *412 ing until the lateral sewer was constructed and their property enhanced in value, were not estopped from denying the power of the city to construct the sewers, and make the assessments in question, or (e,) whether the manner in which the assessment was made did not justify the plaintiffs in still invoking the equitable jurisdiction of the court on the ground that the apportionment of the total cost, and the assessments having been illegally made, did so mingle the amount which w<as due from the respective lot owners with an amount which was not due by them, that it was impossible to determine these respective amounts from any statement made in the pleadings, and that the relief sought ought to be granted notwithstanding the fact that a tender of the amount really due was not made or offered to be made in the petition by'which the plaintiff sought relief.

■ The authority of the city council to make the contract under consideration is derived, if it exists at all, from the Session Laws of 1897, chapter 6, article 3, as follows:

"That in cities of the first class, the city council may, by ordinance, provide for the extension or construction of lateral sewers constructed at the costs of the city, and shall be authorized to levy a special assessment on all lots abutting upon such sewer, and shall apportion such levy to the various'! lots, according to the actual cost of labor or material expended in constructing such lateral along the lot assessed. If the lateral be built in a street or alley having lots on both sides, the cost shall be apportioned to the lots on both sides of such lateral. The costs of constructing such lateral across streets where no lots are abutting, shall be apportioned to all the lots assessed. Such assessments shall be made and be collected in the manner provided for levying and collecting special assessments in other cases, in cities of the first class.v

*413 It is contended, by the defendants in error that the city council had no authority to enter into a contract, and that the contract made with Black & Laird was without warrant of law and void, and that there is no way by which the “actual cost of labor and materials” can be ¡ascertained except by the actual construction by each lot owner of the lateral abutting upon his particular lots, or in case he neglected after due notice to construct such lateral, then by the city authorities themselves, and that, under the law as it exists in this territory, whether the work is done by the owner of the lot or lots or by the city authorities themselves, the materials used must be selected or designated by the authorities, and the labor performed under the supervision and direction of the city engineer and street commissioner; that that is what these officers are for, and that the statute contemplates that the construction of the laterals shall be done by the lot owners, and that this is the only way in which the taxpayers and lot owners know what the “actual cost of labor and material” is.

This position cannot be sustained. There is no such limitation upon the powers of the city council. The power expressly given is that the city council may, by ordinance, “provide for” the extension or construction of laterals. It is true that the “actual cost of labor or material expended” in constructing such lateral along the lot assessed constitutes a limitation, but it is a limitation upon the power of the council to incur costs and expenses, and not a limitation upon the manner or mode which they shall adopt to “provide for” the construction of sewers. If the city council did not exceed the “actual cost of labor or material expended” in constructing the sewer they are left free to “provide for” the work in the *414 manner in which they may find best suited for it, and in “providing for” the construction they may do so by contract with outside parties.

This contention is not open in this case, since the answer of the defendants averred that the charge for the work was “not in excess of the actual cost of constructing the same.” The case is here upon demurrer to the answer, and the fact, as stated in the answer must be true, and is in strict compliance with the language of the statute. If it were not so, we should jet hold that the 'provision that the assessment should be “according to actual cost of labor’’ or material expended,” was complied with by a contract which, in the terms of the answer} was given to a firm which made the, “lowest and best bid” submitted to the mayor and city council.

In Hitchcock v. The City of Galveston, 96 U. S. 341, the statute of the state of Texas had provided, by section 8, article 3, title 4, that the city council should have power “to establish, erect, construct, * * * culverts and sewers, sidewalks and crossways. * * * ” The supreme court of the United States held that “The city is thus authorized itself to construct sidewalks and, though the cost of construction is' to be defrayed by the abutting, lot owners, the city is to collect from them the cost. * * * It is not to be denied that this section confers upo a the city council plenary authority to construct the sidewalks, and to do whatever is necessary for the construction, not prohibited by some other provision of law. * * * And if the city council had lawful authority to construct the sidewalks, involved in the authority was the right to direct the mayor, and the chairman of the committee on streets and alleys, to make a contract on behalf of the city for doing the work. We spend no time in vindicating this proposition. It *415 is true the council could not delegate all the power conferred upon it by the legislature, but like every other corporation, it could do its ministerial work by agents. Nothing more was ■done in this case. * * * There was, therefore, no unlawful delegation of authority.”

In Cummin v. Mayor and City Council of Brooklyn, 11 Paige, p. 600, it was provided by the 40th section of the city charter, that the common council should have general authority to cause the streets and avenues to be improved, and “drains and sewers to-be constructed.” And it was held there by Chancellor Walworth that under the general powers of a corporation, the mayor and city council were competent to enter into a “general contract” to do the work in the city, and that “there is nothing in the charter which prohibits the corporation from entering into general contracts for the making of such improvements.”

In Galveston v. Heard, 54 Tex. 420, upon the power of the city to “construct” sidewalks, sewers, and so forth, and to provide for the cost of them, it was held that the city of Galveston had power to undertake the construction of sidewalks, but that the lot owners would only be liable for the actual cost, and that in providing for this actual cost the city had the power to contract for the improvements, and that the price which the city agreed to pay to the contractor was the actual cost of construction.

And it is said in Dillon’s Municipal Corporation, vol. 2, sec. 810, that:

“Power to a municipal corporation to make local improvements, though the expense be directed in the constituent act *416 to be assessed upon the property benefited, gives the corporation, in the absence of provisions evincing a different legislative intent, the implied power to make general contracts therefor."

Since, therefore, it has been held by the supreme court of the United States that “authority to construct sidewalks" gives to the mayor and city council authority to make a contract therefor, an opinion which is agreed to upon the same statute by the supreme court of Texas, and since it was held by Chancellor Walworth that a section of the city charter which “gives general authority to the common council to cause the streets and avenues to be constructed” and that the mayor and city council having the general powers of a corporation, are competent to enter into a general contract for such improvements, and since there is no prohibition upon the city council from entering into a general contract for the making of such improvements, and since this position is affirmed by Judge Dillon, we may safely say that when the legislature of Oklahoma authorized the city council “to provide for the extension or construction of laterals to main or lateral sewers," that the power was thereby expressly given to the city council to maxe a general contract for such extension or construction.'

It is further contended by the defendant in error that the act under consideration is inconsistent, for the reason that it is in violation of the provision of the organic act, that all taxa-s tion must be uniform and in proportion to the value of the property subject to taxation. The provision is, that:

“No taxes shall be imposed upon the property of the United States, nor shall any law be passed impairing the right of private property, nor shall any unequal discrimination be *417 made in taxing different kinds of property, bnt all property subject to tbe taxation shall be taxed in proportion to its value. * * *” (Organic Act, section 6.)

It is conceded that the power derived from the state by which special assessments are made against abutting lots for the purpose of defraying the cost of local improvements, is derived from the power to collect taxes. Bnt the authorities are uniform, to the effect that such assessments are no part of those general taxes imposed for the purpose of carrying on the ordinary expenses of the state, and do not therefore come within the provision of the organic law which requires that all taxes shall be. according to the value of the property taxed.

It was said in Emery v. San Francisco Gas Co., 28 Cal. 345, that the words “taxation” and “taxed” in section 13 of article 11 of the constitution of that state which provides that “taxation shall be equal and uniform throughout the state. All property in this state shall be taxed in proportion to its value,” relates to such general taxation upon ail property as is levied to defray the ordinary expenses of the state, town and municipal governments, and not to assessments levied on the lots fronting on a street in a city to pay the expenses of their improvements.

The court there said that “there is another class of expenses, also of a public nature, necessary to be provided for, peculiar to the local governments of counties, cities and towns, and even smaller subdivisions, such as opening, grading, improving in various ways, and repairing highways and streets, and constructing sewers in cities, and canals and ditches for the purpose of drainage in the country. They are generally of peculiar'local benefit. These burdens have always, in every *418 state, from its first settlement, been charged upon the localities benefited, and have been apportioned upon the various properties, but whatever principle of apportionment has been adopted, they have been known, both in the legislation and ordinary speech of the country, by the nam!e of assessments. Assessments have, also, very generally, if not always, been apportioned upon principles different from those adopted in taxation, in the ordinary sense of that term; and any one can see, upon a moment’s reflection, that the apportionment, to bear equally, and do substantial justice to all parties; must be made upon a different principle from that adopted in taxation, so-called.”

The distinction is fully explained by Judge Dillon, in Municipal Corporations, vol. 2, secs. 755 and 778.

Section 778 is as follows:

“But aside from the rule of strict construction which applies to exemptions from taxation, the cases’ cited in the previous section will show that there is, in their ordinary use, a recognized difference between the words ‘tax’ and ‘assessment,’ •and that the one does not always, or usually, include the other. Thus; a constitutional provision that ‘taxation shall be equal and uniform throughout the state’ does not apply to local assessments upon private property to pay for local improvements. So, a provision of the constitution of a state which requires ‘the rule of taxation to be uniform,’ in connection with another provision, that ‘it shall be the duty of the legislature to provide for the organization of cities, and to restrict their power of taxation, assessment, etc., so as to prevent abuses in assessments and taxation,’ is construed not to apply to special assessments by municipal corporations, made by authority of the legislature, for local improvements.”

And the rule is announced by the supreme courts. of *419 many of the states, among others, in Garret v. St. Louis 25 Mo. 505; Hinds v. Leavenworth, 3 Kan. 186; Borough of Greensburg v. Young, 53 Pa. St. 284; Motts v. Detroit, 18 Mich. 494; and by the supreme court of the United States in Ill. Cent. R. R. Co. v. Decatur, 147 U. S. 199.

But the improvements having been made, the assessment upon the various lots abutting upon which the extension of the lateral sewers was made, under section 3 of the city ordinance providing that “when said extension and construction is completed, the mayor and city council shall apportion the cost and expense of said extension and construction, calculating each section of section .1 of this ordinance separately, to the various lots abutting on such extension which shall be a special assessment against each and every lot abutting on said lateral sewer.”

Under this section of the ordinance the total expense of the construction of the lateral sewers in each district in which the lateral sewers were respectively constructed was apportioned equally to each of the lots in such district. And this apportionment is resisted by the plaintiffs, not only upon the grounds previously stated, but also upon the ground that the Statute Laws of 1897, chapter 6, article 3, provides that:, “The city council shall be authorized to levy a special assessment on all lots abutting upon such sewer, and shall apportion such levy to the various lots, according to the actual cost of labor or material expended in constructing such lateral along the lot assessed.” The statute seems sufficiently plain if we pursue the rule by which we are required to accept a statute in its literal meaning, if that literal meaning be such as can be easily and readily understood, and which is susceptible of *420 enforcement. The statute here directs the special assessment to be made for the construction of each lateral sewer on all lots abutting upon such sewer, and then lays down the rule upon which such apportionment shall be made. We do not understand that the word “apportion” means that a certain ascertained sum shall be divided equally among certain persons. Apportion is simply, to divide. If the direction of the statute had been to apportion the total amount of cost ascertained for the lateral sewer, and had not furnished any rule by which the apportionment should be made, it would be fairly in-ferable that the legislative authority intended that the apportionment should be made equally. But the statute in this case does expressly fix a rule by which the apportionment shall be made, and it is not that of equality. It does expressly provide that the assessment of the various lots shall be “according to the actual cost of labor or material expended in constructing such lateral along the lot assessed.” The method of apportionment here established is entirely practical. It may be difficult, but the actual cost of constructing such lateral along and in front of each lot assessed may be ascertained, and if the actual cost of the labor and material expended in constructing the lateral along all of the lots assessed which abut upon the lateral sewer under consideration be correctly ascertained, ithe special assessments will together constitute and make the total amount which is due for the construction of such lateral sewer. It is strongly contended by the plaintiff in error that the word “lot” should be read “lots” in order to complete a meaning which would sustain the apportionment of the total cost of each lateral sewer equally among all of the various lots abutting upon it. We are not at liberty to alter the language of the statute, in order to sustain a construction of it, simply *421 because tbat construction would result in an apportionment ■of tbe total cost to tbe various lots equally, instead of tbat meaning which we think the statute explicitly and with sufficient plainness expresses, that the rule of apportionment of the total cost of each lateral sewer shall not be that of equality, but shall be the actual cost of the construction of such lateral “along the lot assessed.”

We think, therefore, that the apportionment was made upon an erroneous principle, the principle of equality, not authorized by the statute.

It is contended, however, by the plaintiffs in error that the plaintiffs below, the defendants in error, have now no standing in a court of equity, for the reason that they are estopped to deny the power of the city to construct the sewers under the contract, since they have been aware all the time that the ordinance was passed, the contract made and the work in process of completion, and that they have waited until the improvements were finished and their property benefited and they cannot in that condition of things, maintain in a court of equity an injunction, preventing the making of such assessments.

It may be conceded, and, indeed, the rule is well established, not only in- all of the state courts so far as we have been able to see the decisions, but also clearly announced by the supreme court of the United States, that no one will be entitled to relief in equity to enjoin the collection of an assessment until he shall have shown that he meant to do equity by paying such portion of the taxes assessed against him, as it can be clearly seen that he ought to pay, and that the owner *422 of property will not be permitted to refuse tbe payment of a total assessment where it is clear that he ought to pay a pari, and where it can be seen what that part is. He must first pay what is thus clearly due, and not while some portion of the taxes is manifestly due, embarrass the operation of government or any of its subordinate agencies, such as a municipal corporation, and thus throw the burden of public improvements upon either the corporation itself or upon those Who have expended their money to the benefit of his property.

But it has been explicitly held by the supreme court of the United States, that this rule has no application to a case where the entire tax fails by reason of an illegal assessment, and that in such a case the assessment may be enjoined without the payment or tender of any portion of the tax, since it is impossible for the court to determine what portion is actually due. We now hold that the assessment made in this case was not made in conformity with the statute, is therefore without authority and illegal, and should be restrained. The pleadings in the case furnish to us no means of discriminating and ascertaining what portion of the assessment would be due if the assessment had been made in conformity to the law, and we must therefore hold that the whole assessment as made must fail, notwithstanding the fact that no part of the assessment was paid or offered to be paid. We do not here make a rule precluding the collection of the amount due from the abutting property, when the assessment shall be properly made, holding, as we do, that the contract under which the worji was done was one which the corporation was authorized to make. (Norwood v. Baker, 172 U. S. 291 to 293; State R. R. Tax Case, 92 U. S. 575; Northern Pac. R. R. Co. v. Clark, 153 U. S. 252-272.)

*423 It will be left to the plaintiffs in error to take such steps under the statute, as we construe it, to make a new apportionment upon the defendant’s abutting property for so much of the expense of the lateral sewer against each lot as has been expended in constructing such lateral along the particular lot assessed.

The judgment of the lower court is modified and affirmed.
