The city of Madison and its treasurer claim in justification of the refusal to pay the county the sum of $41,297.07 collected by the city and now in the treasurer’s possession as a tax on the taxable property of the city that parts of the provisions of secs. 1317??? — 1 to 1317??? — 15, Stats., under which the tax was levied by the county, are in conflict with the state constitution and therefore void. This tax was collected pursuant to a levy of the Dane county board to raise a county highway fund under the provisions of this lav/. It appears that this amount had been apportioned and certified by the county clerk as the city’s share of such county tax. The city of Madison does not question that the exertion by the county of its taxing power was for the public purpose of providing and maintaining a system of county highways for public travel. It is however contended by the defendants that the parts of the statutes creating the county highway system which provide that the system “shall begin at the corporate limits of the county seat and of the various market towns and railroad stations of the county and include the main traveled highways leading into each town in the county,” and that the county board shall add to this system “such streets in incorporated villages as directly connect the ends of roads then on said system, and such streets when so added, . . . shall become a part” of this county highway system (par. (a), (b), sub. 1, sec. 1317??? — 3), constitute an arbitrary classification of highways, resulting in unreasonable discrimination against the rights of the people in such cities, and depriving them of the equal protection of the law. The *529argument is made that the exclusion of city streets from the county system of highways deprives city residents, as an integral part of the county taxing district, from receiving the benefits of the taxes imposed on them for highway improvements and confers the benefit of such tax on tfie residents of towns and villages, and thus subjects them to a system of taxation that violates the rule of uniformity guaranteed by the constitution and deprives them of the equal protection of the law in bearing the burdens of taxation.
If the selection of highways for’ the county system is a proper classification within the constitutional powers of the legislature, then no constitutional infirmity is apparent in the legislation here assailed. The scope of the legislative power to deal with the subject of establishing taxing districts for the maintenance and improvement of the highways in the state is exemplified by the legislation embodied in the statutes of this state and by the various cases where such legislation has been assailed as an improper exercise of this power shown by the recorded decisions of this court on the subject. Discussion of the questions here involved could add nothing to the full elaboration of them in former decisions of this court and we therefore deem it sufficient to reiterate in part what has been said by this court on the subject. In Land, L. & L. Co. v. Brown, 73 Wis. 294, 303, 40 N. W. 482, Mr. Justice Taylob, speaking for the court, declares:
“If a rule for taxation should be adopted which limits the right of taxation for public improvements to such property only as it can be shown is directly benefited by such improvement, it would result in endless confusion and litigation, and render void very many acts for the government of towns and counties. ... It is for the legislature to fix the limits of the taxing district, and not for the courts. . . . This court has affirmed the validity of the law concerning the building of bridges, which compels the whole county to contribute to the building of a bridge in one town, and that without regard to the question whether the bridge to be built would be any direct benefit to any other town in the county.”
*530The court also states that no rule of public policy forbids taxation of property for any public purpose which may not directly benefit such property, “and that the justice or injustice of the limits of the taxing district, when fixed by the legislature or some other authority authorized by law to fix the same, cannot be questioned by the courts.” In Jensen v. Polk Co. 47 Wis. 298, 2 N. W. 320, it was declared:
“The legislature must in all cases determine by law what locality or division of the state shall be burdened with the expenses of opening and repairing highways. . . . There can be no doubt as to the power of the legislature to compel the several counties of the state, by general law, to open and work the state roads laid out and located within their respective boundaries; and unless there be some clause of the constitution which expressly prohibits it, the power to do so as to a particular road in a particular county is equally clear.”
Other cases in this court affirming legislative competency to deal with this class of public' improvement adhere to the doctrine that the legislature has power to compel the levy of taxes for such purpose by towns, counties, cities, and villages. This was emphasized in State ex rel. Baraboo v. Sauk Co. 70 Wis. 485, 36 N. W. 396, and was there justified on the ground that
“Highways and bridges are matters of general concern to the people of the whole state; yet the expense of making them, and of keeping them in repair, is generally thrown upon the localities where they are situated. Perhaps this is as fair a rule for apportioning the burden as could be devised; still it oftentimes results in making the property in one taxing district contribute more to the same public purpose than the property in another district. . . . The constitution should not be so construed as to prevent the legislature from distributing an exceptional burden over a larger taxing district unless such construction is - absolutely demanded by its language.”
The court in this case held a law valid which compelled a county to levy a tax upon the taxable property of the county *531except the property exempted in cities and villages maintaining their own bridges, to pay one half of the cost of a bridge in one town of the county. See, also, Battles v. Doll, 113 Wis. 357, 89 N. W. 187; Bloomer v. Bloomer, 128 Wis. 297, 107 N. W. 974; Chicago & N. W. R. Co. v. State, 128 Wis. 553, 108 N. W. 557; State ex rel. Carey v. Ballard, 158 Wis. 251, 148 N. W. 1090; Alexander v. McInnis, 129 Minn. 165, 151 N. W. 899; Chicago, R. I. & P. R. Co. v. Murphy, 106 Iowa, 43, 75 N. W. 680. It is manifest from these adjudications that the provisions of secs. 13l7uv — 1 to 1317m — 15, Stats. 1915, establishing the county as the highway district and imposing the burdens on the taxable property therein for defraying the cost of improvement and maintenance of the system of county highways, are a proper exertion of the legislative power. It is a general law operating uniformly throughout the state and upon the residents within each county. The alleged injustice to residents of cities by compelling them to contribute to the improvement of highways located outside of their municipal territory presents no constitutional objections, and if actual inequalities of burdens result that is a subject for legislative ¡consideration. We discover nothing in the provisions of these statutes excluding city streets from the system of county highways that affects the political rights of city residents differently than those of other residents of the counties who may perchance reside in localities where the local highways.are not made a part of the system. The argument of defendants seems to assume that cities as municipal. corporations have special rights, as such, that are invaded. Towns, villages, and cities may be united into a single highway district, as above shown, and when so united constitute a political subdivision of the state for that purpose, and if the laws governing them operate generally and uniformly throughout the district there is no invasion of the constitutional rights of the different local governments. It is strenuously argued that there is no distinction between streets *532in cities and villages in relation to tbe county highway system, and hence exclusion of the highways of one and inclusion of those of the other is false classification, because the public purpose of improving the highways of the state reasonably requires that no distinction be made between these localities. The distinctions between cities and villages in their corporate political and governmental conditions have often been-adverted to in the decisions. In State v. Evans, 130 Wis. 381, 110 N. W. 241, Mr. Justice Dodge, after referring to a number of such decisions, states: .
“That there are distinctions between large and dense communities and small and sparser ones as separate classes is, of course, obvious. That such differences are germane and relative to some purposes of legislation has been declared, almost without limit, by courts. Smith v. Burlington, 129 Wis. 336, 109 N. W. 19, and cases there cited. . . . As to the cogency or propriety of either the regulations made or of the importance of the distinctions, as we have so often said, the courts have little concern. Those subjects rest with the legislature* and only when the court, in the exercise of the utmost deference toward that other branch of the government, is compelled to say that no one in the exercise of human reason and discretion could honestly reach a conclusion that distinctions exist having any relation to the purpose and policy of the legislation, can it deny it validity” (citing).
The case proceeds to point out the many distinctions between urban and rural communities which are proper considerations for legislative discretion in exercising the lawmaking power in behalf of each class'. And so here the peculiar conditions that are necessarily incident to and distinguish the construction, improvement, and use of city streets from the construction, improvement, and use of town and village roads and streets are so marked and varied that they present a legislative question in deciding whether or not it would be practicable and feasible to include city streets as a part of the system of county highways contemplated by this law. We are convinced that the conditions and uses of city streets as compared *533with the town and village highways present a proper subject for legislative discretion concerning the desirability and practicability of uniting them into one system of county highways,, and that the legislature did not transgress its power in this respect.
Another consideration urged by defendants is- that the provisions of sub. 8, sec. 1311m — 5, Stats. 1915, creating a committee to be elected or appointed by the county board to act with the state highway commission and the county commissioner in the administration of the law, are invalid. The powers and duties of this committee are specifically prescribed. It is contended that this subsection delegates powers and authority to such committee which are conferred by the constitution on county boards and county clerks. These powers and duties of this committee are clearly administrative in their nature and in no way conflict with the duties imposed by law on county clerks. The committee can only carry out the road improvement authorized by the county board and perform administrative features connected therewith. It is suggested that they have the ultimate power to pass on the legality of claims for services and material furnished for the construction of roads and bridges. The duty to “audit” such claims as provided by par. (3) (e) of this subsection is not to be interpreted as abrogating the duties imposed by law on county clerks, nor is it to be considered that such “audit” implies that the committee is given power to finally pass on the allowance or disallowance of claims against the county. It is evident that their duties under this part of the act are to examine claims to ascertain whether or not they pertain to and properly itemize the charges for material furnished and work done, and to check the items as to their correctness in these respects to assist the county clerk and the county board to determine whether they are just and legal claims. We think the authority of the county highway commissioner under sub. 3, sec. 1311m — I, Stats., does not conflict with the authority *534of tbe county board to audit and determine tbe validity of claims paid by tbe commissioner in tbe prosecution of tbe work authorized by tbe county, and tbat these provisions do not repeal tbe laws in force when this' section was adopted, respecting tbe authority vested in tbe county board and county clerk prescribing their duties pertaining to claims against tbe county.
Tbe judgment appealed from correctly excluded recovery of tbe sum of $5,813.51 as taxes levied for county aid to tbe building of bridges in towns pursuant to tbe provisions of sec. 1319, Stats. • Tbe trial court awarded recovery of $41,297.07 and imposed a five per cent, penalty on this amount under sec. 1117, Stats. 1915, upon the authority of Oneida Co. v. Tibbits, 125 Wis. 9, 102 N. W. 897. In tbe Titbits Gase tbe town treasurer, through bis failure to collect tbe town tax as required of him, was unable to'make settlement of tbe taxes included in bis tax roll within the time required by law and hence be was subjected to tbe five per cent, damages provided by this section. It is manifest from tbe provisions of this section that these penalties are imposed on tbe treasurer for official delinquencies resulting from bis failure to perform tbe duties imposed on him by tbe law. ' Tbe defendant Garl Moe,, as city treasurer, bad performed the duties of collecting this tax and was ready to settle with tbe county treasurer for tbe tax within tbe time required by law, but was directed by the common council of tbe city to retain this money until the validity of tbe law authorizing tbe tax bad been tested in legal proceedings. Tbe challenged legislation involved constitutional questions of sufficient gravity to justify tbe treasurer in obeying tbe direction of tbe common council. Under these circumstances it cannot be reasonably said tbat tbe city treasurer has failed to perform bis official duties within tbe requirement of sec. 1117, Stats. 1915. To bold otherwise would penalize the treasurer for obeying tbe commands of the common council and for protecting himself and bis bondsmen *535against a possible liability fox the whole tax, if the courts found it to be invalid. Under these circumstances and conditions it must be held that the city treasurer is not subject to the penalty provided by sec. 1117. Erom'this it follows that the court erred in awarding recovery of five per cent, damages on the amount due the county. The judgment must be modified by deducting therefrom the sum of $2,064.85, and as so modified the judgment is affirmed.
By the Court. — It is so order'ed.
