“Tbe legislature shall establish but one system of town and county government, which shall be as nearly uniform as practicable.” Sec. 23, art. IV, Const. This section of tbe constitution has been many times before tbe court, more frequently with reference to counties than to towns, although it refers to each in tbe same terms. At and prior to tbe time of tbe adoption of tbe constitution there existed eohsiderable diversity in town and county government in tbe territory of Wisconsin. In some counties there were three county commissioners elected at large, and in some a board of supervisors consisting of tbe chairmen of tbe town boards of tbe constituent towns. By tbe revised statutes of tbe territory (Terr. Stats. 1839, pp. 103, 104, §§ 1-9) there appears to have been-a uniform system of county government vested in a board of three county commissioners whose general powers were provided for by sec. 13, p. 105. Soon after this tbe territorial assembly began to organize town governments by special acts and also to organize new counties, some of which were governed by a board of county commissioners and some by supervisors. Towns were organized, but tbe local governments thereof were not uniform. So that on tbe whole .there was considerable diversity in town and county government. R. S. 1849, eh. 10, sec. 25, provided that tbe county board of supervisors should consist of the chairmen of tbe boards of supervisors of tbe several towns *286and the supervisors in any city in the county who were authorized to sit in the county board; sec. 7, Id. that the powers of a county as a body politic and corporate could only be exercised by the board of supervisors thereof; and sec. 21, Id. prescribed the general powers of the county board in outline similar to the present statute. Sec. 28, Id. conferred certain special powers upon them, subject to such modifications and restrictions as the legislature should from time to time prescribe. Subd. 6 of sec. 27 provided among the general powers of the county board that such board should have power “to represent the county and to have the care of the county property, and the management of the business and concerns of the county, in all cases where no other provision shall be made.” This continued in force down to the present time. Subd. 6, sec. 669, Stats. (1898). The earlier decisions of this court construing sec. 23, art. IV, Const, seem to place considerable stress on this section as a prohibition against the enactment of special laws for a particular town or county. State ex rel. Peck v. Riordan, 24 Wis. 484, 492 (1869); State ex rel. Keenan v. Milwaukee Co. 25 Wis. 339 (1870). In the case last cited it is said:
“In this they must have aimed at the evil of special legislation. That this is a great and serious evil every one at all familiar with legislative experience knows. The members are constantly annoyed by persons among their constituents who are anxious to amend the laws regulating their local concerns. The local member naturally yields to the local pressure, whether in harmony with his own views or not; and the legislature, usually without much consideration, enacts such local measures as the local members may ask. And thus the public time and money are spent in enacting laws that are frequently of an unwise and improvident character. It is an evil that there have been many efforts to check; and I can conceive of no other motive for the clause in the constitution requiring the system of county and town government to be as uniform as practicable except to prevent such special legislation, varying the system in different localities, as might not amount to an actual destruction of its unity.”
*287Somewhat similar views are expressed in State ex rel. Peck v. Riordan, supra, wbicb was the first ease that arose calling for the construction of this constitutional provision. If we look at the volume of Private and Local Laws each year, swelling from 396 pages in 1861 to 1,469 pages in 1868, and glance through the pages of the latter, we will find much to confirm the statement of the learned justice that special legislation at that time had grown to be a great and serious evil. Of the first hundred acts of the legislature recorded in the Private and Local Laws for 1868, forty are special acts relating to the local government of towns and counties, and a cursory examination of the remainder of the volume would indicate that about that proportion held good throughout. In 1871 an amendment to the constitution was consummated by which it was provided:
“SbctioN 31. The legislature is prohibited from enacting any special or private laws in the following cases: 1st. Eor changing the name of persons or constituting one plerson the heir at law of another. 2d. Eor laying out, opening, or altering highways, except in cases of state roads extending into more than one county, and military roads to aid in the construction of which lands may be granted by congress. 3d. Eor authorizing persons to keep ferries across streams at points wholly within this state. 4th. Eor authorizing the sale or mortgage of real or personal property of minors or others under disability. 5th. Eor locating or changing any county seat. 6th. Eor assessment or collection of taxes or for extending the time for the collection thereof. 7th. Eor granting corporate powers or privileges, except to cities. 8th. Eor authorizing the apportionment of any part of the school fund. 9th. Eor incorporating any town or villáge or to amend the charter thereof.
“Section 32. The legislature shall provide general laws for the transaction of any business that may be prohibited by section thirty-one of this article, and all such laws shall be uniform in their operation throughout the state.”
These sections are now a part of art. IY of the constitution, except that sec. 31 has been since amended so as to pro-*288bibit special or private laws for incorporating any city as well-as for towns or villages.
It'may be useful to classify the cases that bave arisen under sec. 23, art. IV, with reference to tbe subject of litigation, ratber than to arrange them chronologically, or merely classify them into those wbieb bold certain legislative acts valid and those which bold other legislative acts invalid.
Eirst. With reference to the rmmber of supervisors in counties. Where a special law provided for a county board of eight supervisors in a certain county which under the general statute relating to county government would have but three, there is a conflict with the section of the constitution in question and the special act is void. It is said that uniformity was here attainable, the diversity unnecessary, and that the act was special. State ex rel. Peck v. Riordan, 24 Wis. 484. Notice that this same opinion treats as valid a general law regulating the number of supervisors not uniform in its operation, but only uniform with respect to a class created by other laws making assembly districts. Where a general law provided that in counties containing only one town the board of supervisors of that town should constitute the county board, while in all other counties the county board consisted of the chairmen of the several town boards of supervisors, the law was held valid. Cathcart v. Comstock, 56 Wis. 590, 14 N. W. 833. Where the general law provided for the election of one member of the county board of supervisors from each ward and part of a ward of every city, and the city of Chilton, in Calumet county, had three wards, but the charter of that city provided that the mayor of the city should be the sole representative of the city in the county board of supervisors, thus giving the county two less supervisors than other like counties electing under the general statutes, the charter provision was held valid upon the ground that absolute uniformity is not demanded, but only uniformity as nearly as practicable, and that the legislature deter*289mined that such uniformity of representation in this county board as so constituted would thus be secured within the scope and intent of this constitutional provision. Nothing is said as to whether the charter provision was or was not considered a special act of the legislature. State ex rel. McCoale v. Kersten, 118 Wis. 287, 95 N. W. 120 (1903).
Second. Additional officers authorized to perform pari of the duties which the general statutes impose upon the county hoard. Where a special act appointed three commissioners to superintend the erection of a courthouse in the county of Milwaukee and the general law conferred powers on all county boards to build and keep in repair county buildings, the special act was held invalid because contravening this provision of the constitution, because a special law, and because uniformity in this respect was considered by. the court to be practicable. On this last point the court said:
“But the constitution requires the system to be only as uniform as practicable. And this, it is said, does not require absolute uniformity, nor that the same state of things should exist in all the counties. This is very obvious. A uniformity that is impracticable is not required; but, as already shown, that here in question is practicable. And the different boards of different counties may, in. the exercise of their general powers of county government, produce very different results. But all that does not touch the unity or uniformity of the system. . . . Because some departures from absolute uniformity may be sustained under this clause, it will not do to say that, therefore, all departures can be, and that the provision itself is capable of no practical enforcement. Its language is positive and imperative, in no wise like that of provisions designed to refer questions wholly to the judgment and discretion of the legislature. When a case arises under it, where the question, whether a greater uniformity were practicable or not, is doubtful, as in all other such cases, the law would receive the benefit of the doubt.” State ex rel. Keenan v. Milwaukee Co. 25 Wis. 339 (1870).
A special act providing for the office of county auditor whose disallowance of a claim against the county should be *290final, unless thereafter allowed by two thirds of the members-elect of the board, was held void. State ex rel. Walsh v. Dousman, 28 Wis. 541.
Where a special law (ch. 509, P. & L. Laws of 1868) provided for the election of a superintendent of the poor by the electors of the county at the general election; gave the person so elected power to appoint an assistant or bookkeeper, a superintendent of the county farm and poorhouse, a keeper of the hospital, and such other assistants as might be required subject to the order and approval of the board of supervisors; provided an annual salary; required the superintendent to give bond to be approved by the county judge and chairman of the county board of supervisors; provided that he should have the general superintendence of the poor in said county under the supervision of the board of supervisors; that he might make by-laws and adopt rules and regulations for the support and maintenance of the poor in his county, not inconsistent with the laws of the state and such as should be approved by the supervisors; required him to make report under oath to the board of supervisors, giving a detailed statement of the condition of the affairs of his office together with the receipts and disbursements of the same; and made him subject to removal by the board of supervisors for failure to make this report or for official misconduct or wilful neglect of duty, — the law was held valid. State ex rel. Grundt v. Abert, 32 Wis. 403. The general law at this time authorized county boards to elect by ballot three superintendents of the poor, who should constitute a corporation of a given name and possess the usual powers of a corporation for public purposes, who would be capable of purchasing and holding real estate for the benefit of the county with power to convey the same when directed by the county board. These superintendents had the general charge of the poor in their county, had power to make by-laws and regulations to be approved by the county board, and were at all times subject to the control and *291direction of that board in all things pertaining to the care and support of the poor. They were subject to removal at the pleasure of the board, were required to give bond, and the county board was authorized to audit their accounts. No member of the board was eligible to the office, and the superintendents had the same power as town supervisors with reference to cases of bastardy. 1 Tay. Stats, pp. 723, 727, 742, 743. In the case of State ex rel. Grundt v. Abert, supra, at page 405, the court said:
“We cannot say, as a legal proposition, that the situation of Milwaukee county in relation to the support of its paupers was not such that it was impracticable to intrust that business to three superintendents. And, could we say this, it is not easy to perceive how the uniformity of the general system could be materially disturbed by such change. The only provision in the law of 1868, which at first view might seem to be an innovation upon the general system, is that which deprives the board of supervisors of the power to appoint the superintendent. But, inasmuch as the power of such board over the pauper affairs of the county, and over the superintendent and his assistants, is as ample and complete as it would be under the general law, we are of the opinion (and so hold) that the change in the mode of choosing the superintendent does not affect the uniformity of the system ; at least, it does not affect the same in any material respect, or in any manner prohibited by the constitution. . The courts will not hold, and ought not, that acts of the legislature are unconstitutional, unless they are clearly so. If there is room for reasonable doubt, the validity of the act should he asserted and sustained.”
Erom these cases it is not difficult to deduce a rule that, under the constitution as it existed when the foregoing cases were decided, even a special law creating an additional office in a county, the incumbent of which performs part of the duties elsewhere and under general statutes performed by the county board, will be valid if the functions and duties of such additional office are under the control of the county board, and there may exist in the judgment of the legislature reason*292able ground for considering tbe general law as to tbis particular county impracticable.
Third. Gases relating to salaries of county officials. Oh. Iff, Laws of 1815, required the board of supervisors of Milwaukee county to pay the county treasurer $3,000 per annum in addition to his salary for the purpose of enabling him to employ such clerks and assistants as should be necessary. At the same time the general statutes required the county board to fix the salaries of county officers before their election and prohibited increase or diminution of salary during the official term. It was held that this latter regulation was part of the system of county government, and that the special law applicable to the county treasurer of Milwaukee county violated its uniformity. Rooney v. Milwaukee Co. 40 Wis. 23 (1876). The opinion contains this language:
“The legislature has no power needlessly and materially to impair the practicable uniformity of' the one system of town and county government required by see. 23, art. IV.”
Rut where a law providing for a change of compensation of the sheriff was general and applied in terms to all counties whose boards chose to act under it, although the-same general laws with reference to increase or diminution of salary were in force, the law was held valid. Observe that the law so held valid was general in its terms, but action under it was optional, so that the result would be lack of uniformity when some counties acted under this law and some did not. The court said, among other things:
“The mere fact that the county board of any county may make such change in the method of compensating sheriffs does not interfere with such uniformity. Verges v. Milwaukee Co. 116 Wis. 200, 93 N. W. 44. The decision in the Rooney Oase, cited, was under an act relating to a particular county. Rooney v. Milwaukee Co. 40 Wis. 23. State ex rel. Peck v. Riordan, 24 Wis. 484, cited, was similar in that respect.” State ex rel. Sommer v. Erickson, 120 Wis. 435, 98 N. W. 253 (1904).
*293Erom this we are authorized to infer that, where the law is general in terms and provides for a class of counties where conditions justify a departure from absolute uniformity, some reasonable departure from uniformity will be upheld in matters which are conceded to be parts or functions of county government.
Eourth. Cases relating to the building of bridges or viaducts. In State ex rel. La Valle v. Sauk Co. 62 Wis. 376, 22 N. W. 572, it was held that a law requiring county boards to levy a tax in certain cases for the purpose of building a bridge, and providing that it should apply to all counties in the state except the county of Grant, was invalid as contravening sec. 23, art. IY, Const The court held that the effect of the act in question was to relieve all the towns in the state outside of Grant county from the expense of erecting and maintaining the bridges specified in the act, while it cast all the burden of doing so upon other counties, and that therefore the act was invalid. In Wagner v. Milwaukee Co. 112 Wis. 601, 88 N. W. 577, suit was brought to restrain the county, its supervisors and officers from proceeding in the matter of constructing a certain viaduct and from issuing, selling, or disposing of bonds for that purpose. The county was proceeding under ch. 310, Laws of 1899, which authorized the county board of supervisors of any county within this state to alter, erect, construct, and maintain any viaduct not less than 1,000 feet in length, the cost of construction of which, together with the right of way therefor, shall not be less than $80,000, over and across any gully, river, valley, etc., for the purpose of connecting two or more highways, etc. This act provided for the issue of bonds of such county for the- purpose of raising money, but the amount of bonds so issued should not exceed a sum equal to one fifth of one per cent, on the value of all the taxable property of said county as determined by the last assessment and equalization for state and county taxes. The act was challenged on several grounds. It was held that the *294particular designation of assessed valuation, percentage, and amount pointed out Milwaukee county, it being the only county in the state answering the description, and that the act. was special, and it was said:
“We must hold that the act in question is local and special,, within the meaning of the provision of the constitution quoted. Moreover, it attempts to give to the county of Milwaukee powers of local government not possessed by any other county in the state, and hence it is repugnant to sec.. 23, art. IY, Const.”
But in Bingham v. Milwaukee Co. 127 Wis. 344, 106 N. W. 1071, another suit was brought to enjoin the-issue and. sale of county bonds of Milwaukee county authorized and attempted to be issued for the purpose of building this same viaduct. The bonds were about to be issued under the provisions of ch. 444, Laws of 1903 (secs. 697 — 32—44, Stats.: Supp. 1906), which was a law passed after the failure to. build consequent upon the decision in Wagner v. Milwaukee Co., supra. Ch. 444, Laws of 1903, however, expressly applied to any county within this state “which now has or may hereafter have, according to any state or national census-taken, a population of 150,000 or more.” It also, unlike the act construed in Wagner v. Milwaukee Co., supra, omitted any detail pointing out a particular county. It is noticeable,, however, that it was limited in its operation to counties having a population of 150,000, and was therefore not uniform throughout the state, but only uniform as to a certain class. The briefs of counsel called the attention of the court to sec. 23, art. IY, Const., but the court does not mention that section of the constitution in its opinion. The opinion does, however,, hold the act valid, refuses to enjoin the issue of the bonds, and says:
“Classification of cities by population, and the enactment, of general laws for each class according to its needs, has been so often approved by this court that it has become, part of the fundamental law of the state. State ex rel. Risch v. Trustees, *295121 Wis. 44, 98 N. W. 954. No good reason is perceived why tbe same considerations in a somewhat modified degree, perhaps, do not justify classification of counties by population as well as cities. Indeed, this court has affirmed the validity of an act providing for the payment of a salary to registers of deeds in lieu of fees in all counties containing a population of 150,000 or upwards, on the ground that the classification was proper, and hence that the act was a general act, and not private or local. Verges v. Milwaukee Co. 116 Wis. 191, 93 N. W. 44. While the subject of classification was not discussed at length in this case, it is manifest that it could not have been decided as it was, except on the basis that the classification of counties by population, in legislation relating to the payment of a salary in lieu of fees to the register of deeds, was proper because germane to the subject; the idea doubtless being that in a populous county, where many real-estate transfers are made, the fees provided by law would furnish an extravagant compensation to the register, while in small counties, where the transfers are few in number, the fee system would afford simply a reasonable compensation.” ,j
When we reflect that in Verges v. Milwaukee Co., supra, the question whether the law there under consideration was valid under sec. 23, art. IV, Const., was raised and decided, and when we reflect that the mandate of the constitution prohibiting the incorporation of cities or the amendment of their charters is much more direct and positive in its inhibition than sec. 23, art. IV, Const., the decision in Bingham v. Milwaukee Co. is very significant to indicate that the legislature may by general law applicable to a class of counties bring about changes in county government in particulars where it is not practicable to carry on such government in that particular class of counties in the same manner in which it is carried on in other counties outside of that class.
Eifth. Gases determining what official acts are and what are not functions of town or county government within the meaning of sec. %S, art. IV, Const.

W. 86, and cases cited.
Sixth. Oases which expressly recognize a measure of discretion in the legislature to determine how far uniformity in the particular case is practicable. State ex rel. Peck v. Riordan, 24 Wis. 484; State ex rel. Keenan v. Milwaukee Co. 25 Wis. 339; State ex rel. McCoale v. Kersten, 118 Wis. 287, *29795 N. W. 120; State ex rel. Grundt v. Abert, 32 Wis. 403; State ex rel. Sommer v. Erickson, 120 Wis. 435, 98 N. W. 253; Cathcart v. Comstock, 56 Wis. 590, 14 N. W. 833; Rooney v. Milwaukee Co. 40 Wis. 23.
Seventh. But there is further observable in several well-considered decisions of this court a distinction between uniformity in the rule of law declared by the legislature and uniformity in its adoption by the smaller subdivisions or in its operation upon such subdivisions. This is similar to the question which was before the court in Adams v. Beloit, 105 Wis. 363, 81 N. W. 869, with reference to the stricter provisions of secs. 31, 32, art. IV, Const. The most noteworthy of this class of cases arising under sec. 23, art. IV, Const., is Land, L. & L. Co. v. Brown, 73 Wis. 294, 40 N. W. 482 (1889). In order to understand the force and effect of the case last cited it must be kept in mind that at the time referred to in that decision there were in force in the Eevised Statutes of this state two separate and complete systems of local government, one for the government of towns and one for the government of villages: ch. 38 and ch. 39, E. S. 1878, relating to towns, and ch. 40, Id., relating to villages. The powers of the village board of trustees were much more extensive than those of the town board of supervisors. Ch. 292, Laws of 1883, a law, general in form, provided that all the powers relating to villages and conferred on village boards by ch. 40, E. S. 1878, except those in conflict with the town laws, should be exercised by the town boards in those towns which contained within their boundaries one or more unincorporated villages of 1,000 population or greater. The effect of this act was, of course, that towns within the boundaries of which were one or more unincorporated villages of 1,000 inhabitants had a system of government not uniform with other towns in the state having within their boundaries no unincorporated villages or an un*298incorporated village or villages of less than 1,000 population. The court said:
“It is also argued that ch. 292, Laws of 1883, violates the provisions of see. 23, art. IY, of the constitution, which provides that The legislature shall establish but one system of town and county government. And we are informed that the learned circuit judge in sustaining the injunction in this case was of the opinion that the act was a violation of the said sec. 23, art. IY. We think the learned circuit judge was mistaken in his opinion. Oh. 292, Laws of 1883, is an amendment of the laws concerning towns and the government thereof. Like many other laws of the state, it provides for the exercise of different powers by the boards of different towns, when there is anything in a town which calls for the exercise of such different or additional powers. The act is as general as any other general act. It provides for the exercise of the additional powers in all towns in which villages are situated having a given number of inhabitants. It is not subject to the criticism that, though general in form, it is special in fact, as it is a matter of public notoriety that there are and have been several towns in the state to which the act can be applied. To hold that this section of the constitution requires the legislature to make all laws for the government of towns applicable to every town in the state, without any regard to the wealth, population, or other peculiarities of such towns, would be to hold a very large portion of the legislation on the subject of towns in this state unconstitutional and void. As instances of these laws, see sec. 1240, E. S. 1818, in regard to the assessment of highway taxes, and sec. 1320, in regard to building bridges. It is clear that the act in question is not a violation of the system of town government, but a part of the system, in order to> adapt the system to the peculiar wants of certain towns in the state."
To the statutes instanced by Justice Tavloe in the opinion last quoted we might add sec. 610, Stats. (1898), and also sec. 32, ch. 28, R. S. 1849, the same as Stats. (1898), sec. 1519; and see Mappes v. Iowa Co. 47 Wis. 31, 1 N. W. 359, Milwaukee Co. v. Sheboygan, 94 Wis. 58, 68 N. W. 387, and Juneau Co. v. Wood Co. 109 Wis. 330, 85 N. W. 387. But *299tbe ratio decidendi of tbe case of Land, L. & L. Co. v. Brown, 73 Wis. 294, 40 N. W. 482, is that by a general law applicable to all towns óf a certain class, snob as towns having witbin. tbeir boundaries one or more unincorporated villages, tbe legislature may prescribe for sucb towns in that class quite a different form of the same general system of town government. See, also, Jones v. Kolb, 56 Wis. 263, 14 N. W. 177. This phase of tbe question is also touched upon in State ex rel. Sommer v. Erickson, 120 Wis. 435, at page 442 (98 N. W. 255), where tbe court said:
“As indicated, tbe act applied to every county in tbe state.. Tbe sheriff was elected the same as before. His subordinates, were appointed tbe same as before. Tbe office was administered tbe same as before. Absolute uniformity is not required. Tbe system is only to be ‘as nearly uniform as practicable.’ Tbe mere fact that tbe county board of any county may make sucb change in tbe method of compensating sheriffs, does not interfere with such uniformity. Verges v. Milwaukee Co. 116 Wis. 200, 93 N. W. 44. Tbe decision in the-Rooney Case, cited, was under an act relating to a particular; county. Rooney v. Milwaukee Co. 40 Wis. 23. State ex rel. Peck v. Riordan, 24 Wis. 484, cited, was similar in that respect.”
We have taken tbe liberty of italicising tbe word “any” in-, tbe above quotation. Tbe cases - therein cited bear out the-views expressed in tbe quotation. It would seem from State ex rel. Graef v. Forest Co. 74 Wis. 610, 43 N. W. 551, that, this must be tbe necessary construction of a constitution, which by sec. 22 of art. IV authorizes tbe legislature to confer upon tbe boards of supervisors of tbe several counties of ’ the state such power of a local legislative and administrative character as they shall from time to time prescribe, which necessarily presupposes discretion on tbe part of the board off supervisors to exercise tbe delegated legislative power con-formably to local wants and local peculiarities, and also contains tbe section in question here, which restricts tbe legisla*300ture to the establishment of one system of town and county government as nearly uniform as practicable. In the case last cited it must have appeared from see. 670, R. S. 1878, that the general laws of the state authorized the several county boards to set off, organize, vacate, and change the boundaries of the towns in their respective counties, and at the same time apparently destroyed the uniformity of this power by limiting its exercise in certain counties therein named, and the act in question in State ex rel. Graef v. Forest Co., supra, provided that none of the towns in Eorest county should be divided, vacated, or have the boundaries thereof changed by the board of supervisors until the question was submitted to a vote of the legal electors of the town or towns to be vacated and decided affirmatively by a majority of such electors. In the opinion attention is directed to the form of the first sentence of sec. 670, which, however, does not appear to be materially different in this regard from subd. 6, sec. 669, Stats. (1898).
With this resume of cases on this subject in mind we take up the act in question, first recalling the rule of construction as follows:
“It is only when the unconstitutional purpose is clear beyond a reasonable doubt that a court can be justified in declaring void an act of the legislature. Att’y Gen. v. Eau Claire, 37 Wis. 400, 438; Johnson v. Milwaukee, 88 Wis. 383, 389, 60 N. W. 270; Verges v. Milwaukee Co. 116 Wis. 191, 198, 93 N. W. 44.” Nash v. Fries, 129 Wis. 120, 108 N. W. 210.
We must also bear in mind that in ordinary investigations regarding the constitutionality of a statute we have an express interdict in the constitution more or less clear in its terms, while in the case at bar we have first the peculiar language of sec. 23, art. IY, Const., allowing for considerable discretion on the part of the legislature, and making it unusually difficult for a court to pronounce an act unconstitu*301tional because it is not a mere measure of tbe language and meaning of tbe statute against tbe language and meaning of tbe constitution, but also a determination of tbe mixed question that uniformity in the giren case was and is practicable; and second, we have tbe rule of interpretation of statutes reinforced by tbe mandate of constitutional interpretation, both of which command us to find harmony, not conflict,'between tbe provisions of sec. 669, Stats. (1898), relating to tbe general powers of tbe county board, and cb. 94, Laws of 1906 (secs. 697- — 45-49, Stats.: Supp.. 1906). Former .decisions of this court referred to in this opinion settle tbe law for this state that tbe mere enactment by tbe legislature of a law relating to town or county government is not conclusive upon tbe proposition that tbe general law was impracticable in tbe particular case. Tbe first test of tbe constitutionality of cb. 94, Laws of 1905, must be found in tbe inquiry whether or not it displaces or conflicts with general governmental powers given to county boards generally. If we find that it does not, that ends tbe inquiry and resolves tbe question in favor of tbe constitutionality of tbe law. If we find that it does so take away, supersede, and confer on others some of such general powers of county boards, we then inquire whether in tbe judgment of tbe legislature tbe general system might reasonably have been considered impracticable in tbe particular case or class of eases and with refereneé to tbe particular powers so modified, superseded, or taken away. We next consider whether in tbe judgment of this court, resolving all reasonable doubts in favor of tbe validity of tbe act, tbe general system was practicable to cover tbe particular case. If we are not satisfied that tbe general system was practicable in tbe particular instance, we must bold tbe law valid, although it takes away from tbe general powers of tbe board.
From official documents which we may judicially notice, Milwaukee county bad at tbe census of 1900 a population .of *302330,000, considerably more than one seventh of the population of the state. Its population is about eighty-six per cent, urban and fourteen per cent, rural. It contains, as compared with other counties, an unusual proportion of wage earners who are liable by reason of accident or the disasters of life to become a public charge. It .has fifty members in its county board, and its annual expense for support of the poor is more than $165,000. Oh. 94, Laws of 1905 (secs. 697 — 45—49, Stats.: Supp. 1906), applies to all counties now having or which may hereafter have a population of 250,000 or more. It requires the county board of supervisors in such county to elect by ballot five trustees for the terms therein specified and provides that each trustee shall qualify by subscribing an •oath, shall execute a bqnd, and shall receive a fixed compensation. The trustees may for misconduct or neglect of duty be removed from office by the county board of supervisors.
“Said board of trustees when appointed and qualified shall have the same power in all matters relating to the care and support of the poor in such county .as is now vested in the county board and shall have the entire management of the county hospital, county farm, almshouse and waterworks and the department of outdoor relief, and the entire management ■of the support and relief of poor in such county. They shall let all contracts and make all purchases for whatever may be necessary to maintain and, from time to time, improve said institutions and maintain, support and care for the poor in such institutions and shall audit all accounts therefor.” Sec. 2, ch. 94, Laws of 1905 (sec. 697 — 46, Stats.: Supp. 1906).
The power of the board of supervisors under sec. 669, Stats. (1898), is not in any particular expressly taken away, but that section stands as law so far as it may stand consistently with sec. 6, ch. 94, supra, which merely provides that “all acts or parts of acts in conflict with the provisions of this act are hereby repealed.” We would not be justified within the rule of constitutional interpretation above quoted in construing ch. 94 to conflict with or displace the powers granted *303to the county board under sec. 669, Stats. (1898). Aside from the constitution, the rules of statutory construction require us to harmonize these statutes if possible. Considering the constitution, ch. 94, Laws of 1905, must yield at every point where yielding will maintain its constitutionality and ■do no violence to its terms, The care and support of the poor, the management of the county hospital, poor farm, almshouse and waterworks, and the department of outdoor relief, and the entire management of the support and relief of the poor in such county may, and do, relate to the administrative work necessary in such matters. The letting of contracts and making purchases, the improvement of the institutions mentioned, and the maintenance, support, and care of the poor in such institutions and the auditing of the accounts therefor refer to like administrative duties. The words of the act will bear that construction. Indeed, this is their more natural import. These trustees have the power to appoint three superintendents of the poor, and it is the accounts of ■their appointees and the disbursements under their administration that they are required to audit as well as their own ■expenditures and accounts. The county board, in the absence of this law, would necessarily have to transact all such business through a committee appointed • from among its members. Sec. 668, Stats. (1898). This committee would, generally speaking, have the power of the county board in the administration of the affairs of the institutions mentioned. This committee would let all contracts and make all purchases, and do all the things mentioned in sec. 2 of said act of 1905 (sec. 697 — 46, Stats.: Supp. 1906), and yet so long as sec. 669, Stats. (1898), was in force that committee would be subject to the general control and management of the county board itself.
It is quite possible to put a construction on this law that will bring it in conflict with the powers of the county board under sec. 669, supra,. But that construction would resolve *304all doubts against the constitutionality of tbe law instead of in its favor. Under sec. 4 of the act in question the board of trustees is required to file with the county cleric an annual report, together with the reports of the superintendents of the said county hospital, county farm, almshouse, and waterworks and department of outdoor relief, including an itemized statement of receipts and disbursements for the year ending on the last day of September in each year, and also a classified statement of the same and an estimate of the appropriations needed for the ensuing year. The county clerk is required to lay such reports and statements before the county board and shall have the entire/ management of the board has jurisdiction, power, and authority to examine, allow, approve of or disapprove of, under the rules of law, the disbursements and estimates of the trustees. Otherwise why are the itemized statements of receipts and disbursements required to be laid before the county board having the powers found in sec. 669, Stats. (1898) ? The county board is required to make such sufficient appropriations annually in advance for the support, maintenance, salaries, repairs, and improvements of said county hospital, county farm, almshouse, and waterworks and department of outdoor relief and district physicians. This adds nothing substantial to their former duty, which, by necessary implication, required them to do likewise. Under this law there still remains with the county board a reasonable discretion as to the amount necessary for such purposes, and this conclusion is supported by the form of the statute, which requires the trustees to file, for the purpose of presentation to the county board, an estimate of the appropriations needed for the ensuing year.. There is nothing in the statute making this estimate conclusive upon the board. It is advisory only, and, had the legislature intended that it was otherwise, something more than an estimate would have been required, and some provision inserted making it mandatory upon the county board to levy *305that specific amount. Under tbis act the county board still retains the power “to examine and settle all accounts of the receipts and expenses of the county, and to examine, settle and allow all accounts, demands or causes of action against such county; to apportion and order the levying of taxes and direct the raising of such sums of money as may be necessary to defray the county charges and expenses.” Sec. 669, Stats. (1898). The amount of money raised by the county board for this purpose comes into the hands of the county treasurer. It is paid out by him upon warrants signed by the president and secretary of the board of trustees, but all such payments will appear in the annual account required to be filed by sec. 4 of the act, and the requirement that the accounts be presented to the board shows they are subject to audit, and, if illegal, to disallowance, by the county board.
The general framework of this act is very like that of ch. 509, P. & L. Laws of 1868, under examination in State ex rel. Grundt v. Abert, 32 Wis. 403. The substantial difference between the acts is that the law of 1868 provided expressly that the officer should have the general charge and management of the poor in said county under the control of the board of supervisors, while in the case at bar such control of the board of supervisors arises by necessary implication from the fact that there is no express repeal of the general statutes, secs. 669 and 670, conferring powers on the eounty board, that these statutes and ch. 94, Laws of 1905 (secs. 697 — 45—49, Stats.: Supp. 1906), may stand together, and from the rules of law which require us to so hold unless the statutes are irreconcilable beyond reasonable doubt. This consideration is further strengthened by the rules deduced from the preceding cases, that if the functions and duties of the additional office are under the control of the county board, or there may exist in the judgment of the legislature reasonable ground for considering the general law as to this particular county or counties of this class imprae-*306ticable, tbe law may be beld valid. Where the law is general in its terms and provides for a class of counties where conditions justify a departure from absolute uniformity, reasonable departure from uniformity will be upheld. A general law applicable to a class of counties may bring about changes in county government in cases where it is not practicable to carry on such government in that particular class of counties in the same manner in which it is canned on in other counties outside of this class. We are unable to say that conditions in Milwaukee county do not require some departure from the general plan, nor that the law in question transcends the power of the legislature in these particulars; whence it follows that the judgment of the court below should be affirmed.
By the Court. — The judgment appealed from is affirmed, with costs.
