The indictment alleges that two of the defendants are members of the court of county commissioners of the county of Marshall, and that the other defendant is the judge of probate of the county; and that they willfully failed to discharge duties imposed on them by an act of the last General Assembly, approved February 18th, 1897, entitled “An act for the improvement of roads and bridges in Marshall county, Alabama.” (Pamph. Acts, 1896-97, pp. 1228-36.) A demurrer was interposed to the indictment assigning ten causes. The ninth and tenth causes assail the constitutionality of the act, and these causes were sustained, and from the judgment sustaining them, this appeal is prosecuted by the State in pursuance of the statute. Cr. Code, 1896, §4315.
The first insistence in support of the judgment of the court below is, that the act offends the clause of the second section of the fourth article of the constitution, *207which declares, with exceptions it is not now necessary to enumerate, that “each law shall contain but one subject, which shall be clearly expressed in its title.” The proposition in support of the objection that the act offends this limitation,- we state, as is stated in the brief of counsel, “the act is unconstitutional, because its title and body embrace two separate and distinct subject matters, viz,: 1. The improvement of roads. 2. The improvement-of bridges.”
From the multiplicity of judicial decisions, to which this limitation has given rise since its introduction into the organic law of the State, and since the introduction of a corresponding limitation into the constitutions ■ of many of the other States, certain principles may be deduced, governing its construction and application upon which there is very general, if not unbroken concurrence of opinion. The limitation is not excepted from the cardinal rule, that it is only a clear violation of the constitution which will justify the courts in overruling the legislative will. Every legislative act is presumed to be constitutional, and every intendment is in favor of its validity. — Cooley Const. Lim., (6th ed.), 218. While the limitation must be so construed and applied as to avoid and suppress the mischief against which it is directed, the construction must not be strict, embarrassing legislation by making laws unnecessarily restrictive in their scope and operation, or by the multiplication of their number, by an inhibition of the legislature from the incorporation in one act of all matters properly connected with one general subject. — Cooley Const. Lim., (6th ed.), 172. “By-this generous principle of liberal construction,” as it is termed by Mr. Freeman, in the annotations to the case of Davis v. State, 61 Am. Dec. 339, all well considered adjudications are guided. The legislature must for itself determine how broad and comprehensive the subject of an enactment shall be, and the degree of particularity which must be observed in the title defining it. And so ]ong as the generality of a title is not “made a cover to legislation incongruous in itself, and which by no fair intendment can be considered as having a necessary or proper connection,” there is no cause of objection. — Cooley Const. Lim., (6th ed.), 172, 173.- When the title of an act expresses but one general subject, and all its provisions are allied to the subject expressed or, as is usually said, germane *208or cognate to it, all the purposes of the limitation are satisfied. This is the real test in each particular case : When the title expresses one general subject, however broad and comprehensive the subject may be, whether the act includes provisions, which by no fair intendment can be considered as having connection or relation to the subject expressed.
Applying these rules, if we were not compelled to indulge all reasonable presumptions in favor of its constitutionality, we could not hesitate to affirm that the act is free from all just objection as wanting in clearness in the expression of its subject in the title, or of duplicity in the expression of two dissimilar subjects, not having logical and legal connection. It is difficult to conceive of any two matters so treated by the common law, and by legislation, and in popular understanding, as constituting but one general subject, as public roads and bridges. In Elliott on Roads and Streets, 4-5, a road is defined as “a passage ground appropriated to public travel,” and public roads as “such as are open to the public, and under the control of governmental instrumentalities, as counties, townships, road districts and local sub-divisions of a similar character. Such roads are set apart to the public and are maintained at public expense.” In 1 Bouvier’s Law Dictionary (Rawle’s ed.), public bridges are defined as such “as form part of the highway, common, according to their character, as foot, horse, or carriage bridges, to the public generally, with or without toll; though their use may be limited to particular occasions, or the seasons of flood or frosts.” And in the standard work of Elliott, to which reference has just been made (p. 20), public bridges are defined as structures across a creek, river, or other natural body of water, or canal, ditch, or other artificial water way, erected for the accommodation of the public. And it is said, a bridge is an essential part of a road, and the “locating of a bridge is but the laying out of a highway.” In all our legislation, roads and bridges have been associated as parts of one general subject, placed under the superintendence and control of the court of county commissioners. — Olay’s Dig., 506, 1-41. In the subsequent codifications of the statutes, in which they were arranged in chapters and articles, a chapter has been devoted to “Roads, Bridges, Ferries and Water Courses,” *209divided into articles, each- article bnt a subdivision of the general subject. — Code of 1886, § 347, chapter 14, (Code of 1896, § 728, chapter 59). The act is not subject to the objection of repugnancy to the clause of the constitution invoked to defeat it.
The next insistence against the validity of the act is, in the argument of counsel, .embodied in these words : “The Constitution of the State, Art. XI, Sec. 5, provides : ‘No county in this State shall be authorized to levy a larger rate of taxation in any one year, on the value of the taxable property therein, than one-half of one per centum.' This is not only a limitation upon the taxing power of the county, but it is also a grant of a power of taxation to the extent of one-half of one per centum. The power to tax to this extent is, therefore, á constitutional power and can not be interfered with or impaired by legislative enactment. The power to tax is inseparable from the right to control the expenditure of the fund resulting from, taxation. A limitation upon, or an interference with, the control by the county of the fund arising therefrom is a limitation upon or an interference with the power itself. As the legislature can not limit or interfere with the. power itself, it can not limit or interfere with the fruits of the taxation.
The eleventh article of the constitution is devoted to the subject of taxation, and, as was observed by Somerville, J., in Hare v. Kennerly, 83 Ala. 608-11, its several provisions “are not grant of power to levy taxes, but limitations upon that taxing power, which has always been inherent in the State, and vested in the legislative branch of the State government, which is the depositary of all authority on the subject.” And in exposition of the article, it was observed: “It fully recognizes three classes of taxes on property, and three distinct systems of taxation : (1) State taxes, levied for State purposes, and commensurate with the entire limits of the State ; (2) county taxes, levied on property and subjects of taxation in the county, for county purposes’; and (3) municipal taxes authorized by law to be levied for municipal purposes. ”
The fifth section of the article is devoted to county taxation and the first clause, prohibits the grant to a county of authority “to levy a larger rate of taxation in any one year, on the value of the taxable property *210therein, than one-half of one per centum.” The prohibition by its terms, is a limitation or restraint of legislative power, and not of power residing in the county. Counties are involuntary political or civil divisions .of the State, created by statute, to aid in the administration of government. Whatever of power they may possess, or whatever of duty may devolve upon them, originates in and is derived from legislation. They have no inherent power of taxation, nor are they by the constitution invested with such power — all the constitution contemplates is the legislative delegation of such power; and the statutes have delegated the power to ■the court of county commissioners, the agency by which all the powers of the county are exercised. — Code of 1896, §§ 958, 3985. A fallacy of the argument of .counsel, fatal to it, lies in the supposition that the constitution grants to a county power of taxation, and that the power of taxation which legislation may delegate to them, is in any proper sense a constitutional power — it is power derived from the legislature, and may be withheld, or changed, or modified at legislative discretion, no element of contract with third persons intervening, compelling a levy and appropriation of taxes. — Edwards v. Williamson, 70 Ala. 145.
There are events expressed in the fifth section, in which a county may, by legislation, be authorized to levy special taxes, which may be in excess of the maximum prescribed by the first clause of the section — denominated special taxes, because of the special uses or purposes to which they must-be applied. And of them, is the payment of any debt or liability created for the erection of necessary public buildings or bridges. The general'statute, invests the court of county commissioners with authority to levy a special tax for the building of bridges and causeways. — Code -of 1896, §2498. The first section of the act before us, provides that no part of the county revenues, levied and collected for general purposes, shall be appropriated or used in building or repairing bridges; and requires the court of county commissioners, annually, at the time of levying taxes for general county purposes, to levy a special tax, not exceeding one-tenth of one per centum, to be known as the bridge tax, to be paid into the county treasury, kept separate from other county funds, and used in *211building and repairing bridges and approaches thereto, and-for no other purpose, undér the direction of the court of county commissioners. And the court is authorized to obtain temporary loans, to pay such obligations as the county may owe'; or may contract in . repairing and building bridges and approaches, until;íthe tax is collected, and from the taxes when collected to pay such loans. This is the entire provision of the. act in reference to bridges, and we can not- doubt that it conforms to the constitution.
The remainder of the act relates to' the -improvement of roads. The second section requires the court of county commissioners, annually, to appropriate and set apart out of the taxes levied for general purposes, “such, sum as the condition of the county treasury will warrant, but-in no case less than one-eighth of one per centum on the assessed valuation of -the said county, which sum shall be part of the one-half of the one per centum authorized by law for county purposes,”- and this is to constitute a road fund, to be applied exclusively to the improvement of the public roads ; and the manner of its use and application is particularly prescribed. The maintenance and .improvement of public roads has been a legislative policy from the earliest days of organized government; and the policy has been to commit the duty of maintaining and improving them to the several counties, acting through the agency of the court of county commissioners. " Legislative authority is essential to enable the court to make application of the funds of the county, and there has not been a period, when it had not.authority to pay particular claims against the county originating in the maintenance or improvement of public roads. The whole scope of the act is, to create a special fund which must be applied to this public use or purpose. The burdens of the tax-payer are not increased — the limit of county -taxation is not exceeded— the uses or purposes to which the fund must be applied are county uses or purposes, essentially. The legislative power exercised has been of continuous exercise from the beginning of government, and is not in conflict with the constitution.
Nor has section 32 of the fourth article of the constitution, any application to .the act, nor is it a limitation of the legislative power exercised in its enactment. By *212its terms — by its association with other preceding and succeeding sections of the constitution — its subject matter is appropriations from the treasury of the State-. S.urely it has no application to the appropriation by the legislature of taxes it delegates to a county the authority to levy.
The third section- of the act, imposing a specific tax on particular vehicles, without regard to their.value; was, at this term, (Smith v. Court of County Commissioners, ante p. 196) declared violative of the constitutional mandate, that “all property shall be assessed in exact •proportion to the value of such property.” It is an elementary principle of constitutional law, that if some of the provisions of a statute are violative of the constitution,- while others are consistent with it, the latter will be maintained, if they can be separated from and stand without the constitutional parts of the law. The courts will treat- the unconstitutional parts as if they were stricken out of the statute. — 1 Brick. Dig. 361, § 16; Cooley Const. Lim., (6th ed.), 209. Regarding the third .section of the act as stricken out — as- if it had never been enacted — the only result is, that the vehicles therein enumerated become taxable according to their value, and all the purposes of the statute — the improvement of roads and bridges — are capable of being accomplished.
The statute under which the appeal is taken limits the consideration and decision of this court to the constitutionality of the statute drawn in question. If the statute bé constitutional, the judgment adjudging it unconstitutional must be reversed, though it be apparent the indictment founded on the statute cannot be maintained. .In the exercise of the power, it is averred the defendants failed to exercise, they were clothed with power in its nature legislative and judicial. It may well be doubted if the section of the statute on which the indictment is founded, can be so construed as to embrace other than mere ministerial officers, and if it is capable of a larger construction, embracing the members •of the' commissioners' court, whether the indictment should not aver that the official delinquency imputed to them-,, proceeded from -corrupt motives. And there are causes of objection pointed out by the demurrers, which *213were overruled, which it may be, were well taken. These are not now matters for consideration. We cannot, if there is error, in these respects, set it off, as is suggested, against the error of sustaining the demurrers relating to the constitutionality of the act.
■ The judgment must be reversed and the cause remanded.
