The opinion of the Court was delivered by

*480 This action was brought to recover the penalties provided in section 3949 of the Civil Code for the failure of defendant to provide its cars with fenders, as required by section 3950.

• By demurrer to the complaint, defendant attacked the constitutionality of the statute on two grounds: 1. That it denies to it the equal protection of the laws; and, 2. That it contravenes subdivision 9 of section 34 of article III of the Constitution, which provides that “where a general law can be made applicable, no special law shall be enacted.” The first ground was overruled, but the Court held the statute void on the second ground, saying “there is no good reason why the legislature should require fenders to be placed upon cars operated north of a line ten miles north of and parallel to the thirty-fourth meridian.”

*481 1-3 *480 After some diversity of opinion, it has been definitely settled that, while it is primarily for the legislature to decide whether a general law can be made applicable, just as it decides its constitutional power to enact all statutes, it is, nevertheless, ultimately a judicial question Barfield v. Mercantile Co., 85 S. C. 186, 67 S. E. 158; Tisdale v. Scarborough, 99 S. C. 366, 83 S. E. 594. But, in solving the question, the Court will indulge every reasonable presumption and solve every reasonable doubt in favor of the statute. State v. Hammond, 66 S. C. 225, 44 S. E. 797; Commissioners v. Buckley, 82 S. C. 357, 64 S. E. 163. This is a well settled and universally recognized 'rule upon which Courts proceed in testing the constitutionality of a statute. In Hammond’s case, Mr. Justice Jones said: “In determining whether a general law can be made applicable, the judiciary should indulge every presumption in favor of the legislative act, and so it should be presumed that the legislature by the special or local enactment thereby declared its view that the general law could not be made applicable. This conclusion, however, being to some extent at least a question of law, would no more bind the judicial department in-enforcing a *481 constitutional limitation than the legislative determination that a statute is constitutional, which is presumptively involved in the passage of every statute.” * * * “But the applicability of a general law is not simply a question of fact, it involves matter of law; and it is not intended by this Court now to assert that when the legislature has said that a general law cannot be made applicable, that such conclusion may be controverted by any evidence outside of whát appears upon the face of the statute, and upon such matters as to which a Court must take judicial cognizance. Courts will take judicial notice of the division of the State into counties, their names, their locations with respect to each other, population as shown by the United States census, the prominent geographical features of the country, the principal watercourses and their nature and location, matters of commqn knowledge and experience in respect to science and the ordinary operation of the forces of nature. It should-be further stated that the Court should not declare a statute unconstitutional unless the invalidity is manifest beyond a reasonable doubt.” In State v. Burns, 73 S. C. 197, 52 S. E. 960, the same learned justice, speaking for the Court, said with regard to special provisions in general laws (which are permitted by the proviso to subdivision 10 of the same section in reference to subjects not among those as to which special or local laws are expressly prohibited in the preceding subdivisions), that, as to these, there must necessarily be a wider range for legislative discretion. Bor the same reason, the legislative judgment in determining whether a general law can be made applicable must be given due consideration; and, a proper respect for a co-ordinate branch of the government requires that, when the legislature has, by the enactment-of a special law, in effect, declared that a general law cannot be made applicable, its decision should not be overruled by the Courts, if there is any reasonable hypothesis upon -which that decision can be predicated-. In other words, if- circum *482 stances and conditions may exist under which the matter becomes one about which reasonable minds may differ, the Court will not undertake to “run a race of opinions upon points of right, reason and expediency with the lawmaking power.” Cooley Const. Lim. 236. The same principle is applied in determining the validity of classifications made by the legislature in the exercise of the police power. Examination of the decisions of this Court in which statutes have been held to violate this inhibition of the Constitution will show that they are based upon the ground that there was no reason at all why a general law could not have been made applicable, or because they were special, notwithstanding there was already upon the statute books a general law applicable to the subject, which, of course, was, in effect, a declaration by the legislature that a general law could be made applicable.

4,6 Applying these principles to the case in hand, it cannot be said that the classification made by the statute is wholly unfounded in reason. No doubt, at some places on and near the meridian by which the State is divided, the conditions and circumstances existing north and south of it are precisely the same. But every classification is almost necessarily arbitrary in some of its features. It is not necessary to the validity of a classification that it should be made with mathematical precision, or that, in operation and effect, it should result in perfect equality. It does not offend, if, in its main features, it is reasonable.

We know that climatic conditions in the Piedmont section of the State are very different from those which prevail in the lower part, and that the difference becomes more accentuated as we get further from the dividing line made b)' the statute. This difference in climate may require that cars operated in that part of the State should be provided with vestibules for the protection of the motormen, while these would be unnecessary in the milder climate of places south of that line. Where vestibules are necessary, there is good *483 reason for requiring the use of fenders, because the glass in the vestibules, especially when clouded by moisture congealed on it, and the framework which supports it obstruct to some extent the view of the motormen, and increase the danger of collisions, and the fenders lessen the danger of injury in case of collisions.

Another reason why the legislature may have- thought it wise to require cars operated in the upper part of the State to be provided with fenders is that, the ground being more hilly, there are more steep grades and sharp curves in the railroads of that section than in those of the level low country. Other considerations may suggest themselves, but these are enough to show that the classification is not wholly arbitrary.

What has already been said applies with equal force to the first ground of demurrer. Lindsley v. National Carbonic Gas Co., 220 U. S. 61, 31 Sup. Ct. Rep. 337, 55 L. Ed. 369; Barrett v. Indiana, 229 U. S. 26, 33 Sup. Ct. Rep. 692, 57 L. Ed. 1053; Miller v. Wilson, 35 Sup. Ct. Rep. 342, 236 U. S. 373.

Judgment reversed.
