delivered the opinion of the court.
This case comes before us from the Circuit Court of Kossuth County, Iowa, the highest court of that state in which the controversy between the parties could be determined. Rév. Stat. § 709. It was an action for the value of three hogs,' run over and killed 'by the engine and cars of the Minneapolis and St. Louis Railway Company, a corporation existing under the laws of Minnesota and Iowa, and operating a railroad in the latter state. The killing was at a point where the defendant' had the right to fence its road. The action was brought before a justice of the peace of Kossuth County. Proof having been made of the killing of the animals and of their value, and that notice of the fact, with affidavit of the injury, had been served upon an officer of the company in the county where the injury was. committed, more than thirty days before the commencement of the action, the justice gave judgment for the plaintiff against the company for twenty-four dollars, double the proved value of the animals. The case was then removed to the Circuit Court of ’ Kossuth County, where the judgment was affirmed. To review ■ this latter judgment the case is brought here on writ of error.
The judgment rendered by the justice was authorized by § 1289 of the Code of Iowa, which is as follows:
“ Any corporation ¡operating a railway that fails to fence the same against live stock running at large at all points where such'right to fence exists shall be liable to the owner of any such stock injured or killed by reason of the want of such fence *28 for the value of the property or damage caused, unless the same was occasioned by the wilful act of the owner or his agent. And in order to recover it shall* only be necessary for the owner to prove the injury or destruction.of his property;' and if such corporation neglects to.pay the value of or damage done tp; such stock within thirty days after notice in writing, accompanied by an affidavit of such injury or destruction, has been served on any officer, station or ticket-agent employed in the management of the business of the corporation in the county Where the injury complained of was committed, such owner shall be entitled to recover double the value of the stock killed or damages caused thereto.”
■ The validity of this law was assailed in the state court, and is assailed,here, as being in conflict with the first section of the Fourteenth Amendment of the Constitution of the United States, in that it deprives the 'railway company of property without due process of law, so far as it allows a recovery of double the value of the animals killed by its trains; and in that it denies to the company the equal protection 'of- the laws by subjecting it to a different liability for injuries committed by-it from' that to which -all' other persons are subjected.
It is contended by counsel as the basis of his argument, and we admit the soundness of his position, that corporations are . persons within the meaning of the clause in question. It was so held in
Santa Clara County
v.
Southern Pacific Railroad Co.,
We will consider the objections of the railway company in the reverse order in which they are stated by counsel. And first, as to the alleged conflict of the law of Iowa with the clause of the Fourteenth Amendment ordaining that no state shall deijy to any person within its jurisdiction the equal protection of the laws. That clause does undoubtedly prohibit
*29
discriminating and partial legislation by any State in favor of particular persons as against others in like condition. Equality of protection implies not merely equal accessibility to the courts for the' prevention or redress of wrongs and the enforcement of rights, but equal exemption with others in like condition from charges and liabilities of every kind. But the clause does not limitj nor was it designed to limit, the subjects upon which the police power of the State may be exerted. The State can now, as before, prescribe regulations for the health, good order and safety of society, and adopt such measures as will advance its interests and prosperity. And. to accomplish this end special legislation must be. resorted to in numerous cases, providing against aecidents, disease and . danger, in the varied forms in which they may come. The nature and extent of such legislation will necessarily depend upon the judgment of the legislature as to the security needed by society. When the calling, profession or business of parties is unattended with danger to others, little legislation will be necessary respecting it. Thus, in the purchase and sale of most articles of general use, persons may. be left to exercise their own good sense and judgment ;- but when the calling or profession or business is attended with ganger, or requires a certain degree of scientific knowledge upon which others must rely, then legislation properly steps in to impose conditions upon its exercise. Thus, if one is engaged in the manufacture or sale of explosive or inflammable articles, or in the prepara-' tion or sale of medicinál drugs, legislation, for the security of society, may prescribe the terms on which he will be permitted to carry on the business, and the liabilities he will incur from neglect of them. The concluding clause of the first section of the Fourteenth Amendment simply requires that such legislation shall treat alike all persons brought under subjection to it. The equal protection of the law is afforded when this is accomplished. Such has been the ruling of this court in numerous instances where that clause has been invoked- against legislation supposed to be in conflict with it. Thus in

v. Mackey,
From these adjudications it is evident that the Fourteenth' Amendment does not limit the subjects in relation to which the police power of the State may be exercised for the protection of its citizens. That this power should be applied to railroad companies is reasonable and just. The tremendous” force brought into action in running railway cars renders it absolutely essential that every precaution should be taken against *34 acdident by collision, not only with other trains, but with animals. A collision with animals may be attended with more serious injury than their destruction; it may derail the cars and cause the death or serious injury of passengers. Where these companies have the right to fence in their tracks, and thus secure their roads from cattle going upon them, it would seem to be- a wise precaution on their part to put up such .guards against accidents at places where cattle are allowed to .roam at large. The statute of Iowa, in fixing an absolute liability upon them for injuries to cattle committed in the operation of their roads by reason of the want of such guards, .would seem to treat this precaution as a duty. It is true that, by the common law, the owner of land was not compelled to inclose it, so as to prevent the cattle of others from coming 'upon it, and it may be that, in the absence of legislation on the subject, a railway corporation is not required to fence its railway, the common law as to inclosing. one’s land having been established long before railways were known. But. the obligation of the defendant railway company to use' reasonable means to keep its track clear, so as to insure safety in the movement of' its trains, is plainly implied by the statute of Io\Va, which also indicates that the putting up of fences would be such reasonable means of safety. If, therefore, the com.-..pany omits those means, the omission may well be regarded as evidence of such culpable negligence as to justify punitive damages where injury is committed; and if punitive damages in such cases may be given; the legislature may prescribe the -extent to which juries may go in awarding them.
The law of Iowa under consideration is less open to objection than that of Missouri, which was sustained in the case 'cited above. There double damages could be claimed by the owner whenever his cattle had strayed upon the track of 'the railway company for want of fences on its sides, and had been killed or injured by the railway trains. Here such damages can be claimed for like injuries to cattle only where the company has received notice and affidavit of the injury committed thirty days before the commencement of the action, and has persisted in refusing to pay for the value of the property *35 destroyed or tbe damage caused. There must be not merely negligence of the company in not providing guards against-accidents of the kind, but also its refusal to respond ,for the actual damage suffered. Without the additional amount allowed there would be few instances of prosecutions of fail-, road comp.anies vvhere the value of the animals killed, or injured by them- is small, as in this case.; the cost of the proceeding would only augment the loss of ■ the injured party. As said in the Missouri case cited: “The injury actually, received is often so small that in many cases no effort would.' be made by the sufferer to obtain redress, if the private interest were not supported by the imposition of punitive damages.” .115X1. S. 523.
The legislation in question has been sustained in numerous' instances by the Supreme Court of Iowa. In
