This is an appeal from the St. Lonis Court of Criminal Correction.
The information charged a violation of the act of the General Assembly of this State approved March 21,1901 (Laws 1901, pp. 73 and 74), which makes “the emission or discharge into the open air of dense smoke within the corporate limits of cities of this State which now have or may hereafter have a population of one hundred thousand inhabitants, ’ ’ a public nuisance.
The act applies to the owners, lessees, occupants, managers or agents of any building, establishments or premises from which dense smoke is so emitted, and makes the same a misdemeanor punishable by a fine of not less than twenty-five dollars nor more than' one hundred dollars. All such cities are expressly empowered to enact all necessary or desirable ordinances to carry out the provisions of the act.
The information duly verified was filed on the 3rd day of April, 1903. The defendant assailed the constitutionality of the law by a motion to quash, which was overruled and exceptions duly saved.
On October 5, 1903, a plea of not guilty was entered, and the cause was tried resulting in a verdict of guilty, and a fine of twenty-five dollars assessed. Prom the judgment and sentence imposed in pursuance of this verdict this appeal was taken.
The evidence on the part of the State tended quite conclusively to show that on or about the 18th day of March, 1903, the defendant was the manager of the Goodwin Manufacturing Company, and that on that day dense opaque smoke was emitted from the manufacturing plant of the Goodwin Manufacturing Company at intervals from 2:24 p. m. to 3:23 p. m. The evidence on the part of the State further tended to establish that there were various and numerous devices in general use for the abatement of smoke, such as down-draft furnaces, automatic stokers, brick arches, and steam jets, and including smokeless fuel, such as *88hard coal. The coal generally nsed in and about St. Louis is bituminous or soft coal.
The device ordinarily used to abate smoke is the steam jet.
On the part of the defendant, he testified in his own behalf that he had installed various devices in the said Goodwin plant; that the boiler plant used by said company is similar to that of the ordinary boiler plant used by other manufacturing companies in St. Louis; that after using the steam jet device the smoke inspectors objected to it, and he had then tried the “Ideal” smoke consuming device and this also was objected to and he removed it and replaced the steam jets; that he had directed his fireman and engineer to be careful in the use of said device to prevent smoke; that none of the devices will work at all times; that many of them do mitigate the discharge of smoke, but do not prevent it; that the smoke is. densest immediately after firing, and when the boilers are cleaned, smoke is bound to be emitted; that poor coal containing a large amount of slack aggravates the condition; that his engineer is a careful and competent man; that he has not found any device superior to the steam jet contrivance for abating smoke; that about the 18th of March, 1903, it was almost impossible to get good coal by reason of the coal miners’ strike, and the railroad accomodations were inadequate; that he was a member of an association organized to seek relief against the stringent enforcement of the smoke act of 1901. Henry Piatt, the engineer, corroborated the testimony of Mr. Tower.
The court instructed the jury that if they believed from the evidence that in the city of St. Louis and State of Missouri on the 18th day of March, 1903, the defendant, George F. Tower, Jr., was the manager of the Goodwin Manufacturing Company and the said company was at the time a corporation in possession of and operating the building and premises described in the information, and that as such manager on the 18th day *89of March, 1903, he did willfully and unlawfully suffer. to he emitted and discharged from, the smokestack or chimney of said premises dense smoke into the open air, then they would find him guilty and assess his punishment at a fine of not less than $25 nor more than $100.
The court further instructed the jury that if they found there was no known practicable device by which the emission of such dense smoke could, at the time mentioned in the information and in the -testimony, have been prevented, then they would acquit the defendant. That by “practical device” is meant some mechanical device designed for and adapted to the abatement of smoke and which was practicable to be used on the premises in question at the time.
Other usual instructions as to credibility of witnesses, presumption of innocence, and reasonable doubt were also given. ■
The defendant requested the following instructions, which the court refused, and the defendant duly saved his exceptions to such refusal:
“1. The court instructs the jury that by the term ‘practicable device’ is meant some mechanical device by means of which the defendant could without unreasonable expense, loss or damage to his plant or substantial alteration thereof, have effectually abated dense smoke.
“2. The court instructs the jury that before they can.find the defendant guilty of the offense with which he is charged, they must believe and find from the evidence beyond a reasonable doubt that the defendant permitted dense smoke to be emitted or discharged from the premises mentioned in the information within the corporate limits of the city of St. Louis in such' quantities and for such a length of time as to constitute an annoyance or injury either to the persons or property of some of the inhabitants of said city, and *90unless .they so find'from the evidence beyond a reasonable doubt, the defendant should be acquitted.
“3. The court instructs the jury that under the evidence in this case they must find the defendant not guilty.
“4. The jury are instructed that the burden of proof in this ease is upon the State and before they can find the defendant guilty, the jury must from the evidence be satisfied beyond a reasonable doubt that the defendant permitted dense smoke to be emitted or discharged from its premises and they must further be satisfied beyond a reasonable doubt that there was no known practical device that would have prevented the •emission of such smoke at the very time such smoke was supposed to be emitted.”
I. While this cause is here principally upon the ■ constitutionality of the law of 1901, there are other propositions advanced which we must meet. The first is that granting the said act to be constitutional, it ■does not apply to St. Louis, which is a city of over three hundred thousand population, because the act on its face applies to “cities of this State which now have or may hereafter have a population of one hnudred thousand inhabitants.” That is to say, it applies to those cities only which have exactly one hundred thous- and inhabitants, no more, and no less. This contention is predicated on the rule of construction of criminal statutes which requires that they be construed strictly against the State, and liberally in favor of the citizen, and that we must adhere to the strict letter of the law. While the rule of strict construction as to criminal statutes is correct, our courts adopt Lord Mansfield’s view “that tenderness does not require such a construction of words as would tend to render the law nugatory and ineffectual and destroy or evade the very end of it,'nor does it require that we should give in to such nice, strained and critical objections as are contrary, to its true meaning and spirit.” A city having a • *91population of over three hundred thousand inhabitants is a city having a population of one hundred thousand inhabitants. The greater includes the less. The plain obvious meaning of the words “having a population •of one hundred thousand inhabitants.” is having that number of people even if they have many more than "that.
This we regard as too clear for argument; indeed, it is.self-evident.
■ II. Proceeding now to the claims that the statute is unconstitutional, we will consider these in the order •of the brief of the defendant.
It is first insisted that the-Legislature has invaded the judicial province in declaring the emission of ■dense, opaque smoke into the open air of cities having a population of one hundred thousand inhabitants a nuisance, for the reason that -such conduct is not inherently a nuisance. In a word, we assume that the basis of this contention is that, because at common law thick dense smoke was not deemed a nuisance per se, but depended on the character of the smoke, the quantity, the location and. the circumstances, therefore it was not competent for our General Assembly to declare the emission or discharge into the open air of dense smoke within a city of one hundred thousand inhabitants a nuisance.
The power of the General Assembly to pass all needful laws except when restricted by the State or Federal Constitution is plenary, and the Legislature has the power to declare places or practices to the detriment of public interests or to the injury of the health, morals or welfare of the community, public nuisances, although not such at common law. The General Assembly in the exercise of the police power may declare that a nuisance which before was not a nuisance.
Such an act'is properly within that power which is ■conferred by the Constitution of this State upon the General Assembly, in the distribution of the powers of *92our State government. [Lawton v. Steele, 119 N. Y. 226; Mugler v. Kansas, 123 U. S. 623; Mathews v. Railroad, 121 Mo. 298; Moses v. United States, 50 L. R. A. 532.]
Because at common law smoke was not a nuisance per se is no reason why the people of this State, through their representatives in the legislative department, may 'not change that law, and make it a nuisance per se when the location and surrounding circumstances in their opinion and judgment require it. The General Assembly may adopt new regulations from time to time as the occasion and necessity may require. The-State has no higher function than the duty to provide for the safety and comfort of its citizens.
There is nothing unreasonable in this act. Even at common law smoke alone in certain circumstances constituted a nuisance, that is to say, when it produced a tangible injury to property as by the discoloration of buildings, injury to vegetation, the discoloration of furniture, and like cases. [1 Wood on Nuisances, sec. 505, and cases cited; Whalen v. Keith, 35 Mo. 87; Cartwright v. Gray, 12 Grant’s Chcy. 3991.]
It was entirely competent for the Legislature to take cognizance of the fact' known to all men that the emission and discharge of dense smoke into the atmosphere of a large and populous city is of itself a nuisance, a constant annoyance to the general public of such city and one calculated to interfere with the health and comfort of the inhabitants thereof, and to declare it a nuisance per se. ,
The question in St. Louis v. Heitzeberg Packing Company, 141 Mo. 375, was not whether the General Assembly had the power to enact a statute making the emission or discharge of dense smoke in the city of St. Louis a nuisance per se, but whether-said city in the absence of such a law by the State and in the absence of such a power in its charter could declare such emission of smoke in that city a nuisance per se, and it was *93held that the city had no such power; that it was not within the powers conferred by its charter. We have no hesitancy in holding that it was entirely competent for the Legislature .to declare the emission of dense smoke in the open air in a city of one hundred thousand inhabitants a nuisance per se.
In Lawton v. Steele, 152 U. S. l. c. 136, the Supreme ■Court of the United States says: “The extent and limits of what is known as the police power have been a fruitful source of discussion in the appellate courts of nearly every State in the Union. It is universally conceded to include every thing essential to the public safety, health, and morals, and to justify the destruction or abatement, by summary proceedings, of whatever may be regarded as a public nuisance. ’ ’ The General Assembly, charged as it is with this power and •duty, is vested with a very wide discretion and liberty of choice in the means to be adopted to abate the difficulty and nuisance.
It had the power and must be presumed to have inquired into the actual conditions as to the effect of emitting large quantities of dense smoke in cities having a population of one hundred thousand people and the resulting injury to the health and comfort of the public therein, as well as the probable injury to the property-owners in requiring them to use smoke consuming devices, and the discretion exercised by them within their conceded powers we have no power to control unless it involves a violation of some right protected by the Constitution. [Cass Co. v. Jack, 49 Mo. 196; State v. Wear, 145 Mo. l. c. 200; Ex parte Roberts, 166 Mo. 2.07; Fertilizing Co. v. Hyde Park, 97 U. S. 659; Morrison v. Morey, 146 Mo. 543; Holden v. Hardy, 169 U. S. l. c. 392; Com. v. Alger, 7 Cush. 53-84; Lansburgh v. Dist. of Columbia, 11 D. C. App. Cas. 512; State v. Beardsley, 108 Iowa 396; State v. Layton, 160 Mo. 474.]
*94III. It is next insisted that it is a special law and for that reason a violation of article 4, section 53 of the Constitution of Missouri of 1875.
That it is a general law in that it applies alike to all cities having or which may hereafter have a popula-' tion of one hundred thousand inhabitants and to all persons residing therein is clear from its reading. But it is insisted that it is obnoxious class legislation; that if it is a nuisance to emit and discharge dense smoke in a city of one hundred thousand inhabitants it is equally' so in a city of one-half or one-quarter or one-tenth of that size. But is it for the courts to say £hat there is no reasonable distinction between the emission of smoke into the air of a densely populated city and a city sparsely settled, whose inhabitants occupy larger tracts ? If there is ground for dispute of this assumption of defendant, then it is for the Legislature to determine that question for itself. “The constitutionality of a law is not to be determined upon a question of fact in each case, but the courts determine for themselves upon the fundamental principles of our Constitution, which vests the legislative p'ower in the General Assembly, and the rule of construction adopted by our court is Ghat an.act of the Legislature is not to be declared void, unless the violation of the Constitution is so manifest as to leave no room for reasonable doubt. ’r [State v. Layton, 160 Mo. 498-499; Cooley on Const. Lim. (6 Ed.), p. 216; State v. Nelson, 39 N. E. 22.]
But we think the classification is not an unreasonable one. If one corporation or individual may with impunity emit and discharge volumes of dense opaque-smoke into the air of a city of one hundred thousand people then all other corporations, manufactories and. citizens may do likewise, and it is obvious that the proportion of smoke and discomfort will be much greater' than if manufactories and citizens do the same things; in less populous cities where experience shows the de*95mand for such works is much less,- and the consequent accumulation of smoke correspondingly less.
In Ex parte Lucas, 160 Mo. l. c. 236, this court In Banc said: “An act that relates to all cities containing 50,000 inhabitants is a proper classification of natural or artificial persons or subjects, and different regulations for people congregated in such large bodies from those governing people of smaller aggregation, are not illegal or unconstitutional under the Federal or State Constitutions.” [Missouri v. Lewis (Bowman’s case), 101 U. S. 22.] <
In State v. Hayes, 88 Mo. 344, this court held that the allowance to the State of more peremptory challenges in criminal cases in cities containing over 100,-000 inhabitants than was allowed in all other circuits in the State was not unconstitutional as class legislation and that judgment was affirmed by the Supreme Court of the United States. [Hayes v. Missouri, 120-U. S. 68.]
The Legislature had the right to inquire into the-relative evils resulting from the emission of dense smoke in large and populous cities. The suppression of the nuisance was clearly a legislative power and the-whole matter was in the discretion of the Legislature- and it must be presumed that its classification was. based upon satisfactory evidence. Accordingly we hold that in providing that the law should be confined in its. operation to cities of one hundred thousand inhabitants, it did not transcend its authority.
But it is further argmed under this objection that the act is class legislation in that it exempts owners of' premises who may be able to show to the satisfaction of' the court or jury trying the facts that there is no known.practicable device, appliance, means or method by application of which to his building or premises, the emission or discharge of the dense smoke complained of' could have been prevented. The question is, does this, exception or proviso render the act unconstitutional?:
*96It is observed, first, that the defense permitted by this statute is not confined to any particular person or class, but is open to every citizen who can show that there is no known practicable device or appliance by which the emission of dense smoke can be prevented. It was open to defendant and he availed himself of it and undertook to show that there was no device or appliance known by which he could have prevented the emission of thick -dense smoke from his premises and that question was duly submitted to the jury as a question of fact and determined adversely to his contention.
In construing this exception or proviso the history of this legislation may be taken into consideration. The case of the City of St. Louis v. Heitzeberg Pack. Co., 141 Mo. 375, was decided by this court in November, 1897. In that case an ordinance of the city of St. Louis declaring the emission into the open air of dense black smoke or thick gray smoke within the city of St. Louis a nuisance was before us, and it was held that the city under its charter, and in the absence of any statute of this State declaring such emission to be a nuisance, had no authority to pass and enforce such an ordinance. At that late date it was admitted of record by the special counsel for the city that up to that time no device or means was known or had been invented whereby such smoke could under all circumstances be suppressed or prevented, and this court held said ordinance unreasonable because it sought to punish the citizen for creating smoke “in advance of any known device for preventing it.”
When the Legislature came to consider this question, doubtless it was aware of the. judgment of this court in that case, and seemingly concurred in the view that while such dense smoke was unquestionably a nuisance, still as the opponents of the measure insisted there were no known practicable appliances or devices yet discovered or obtainable whereby the nuisance could be prevented and those who favored it insisted there *97were appliances whereby it could be prevented, the Legislature deemed it best to allow such defense, in all' cases, to be heard and determined by the court or jury trying the case. If, as was contended by those who favored the enactment,' there were numerous practicable devices by which the objectionable smoke could be prevented or abated, the result would be that there would be no exemptions. If on the other hand it could be shown there were none, then it was deemed unjust to punish the citizen or corporation pursuing an otherwise lawful business for an act which he or it could not prevent.'
As already said, does the permitting of this defense to all persons alike render the whole act unconstitutional on the ground that it is class legislation in favor of those persons who show- they can not prevent by any known appliance the emission of dense smoke from their buildings or premises ?
Since the decision in the Heitzeberg case it would seem from the evidence that there has been much progress made in smoke preventing appliances. The witnesses testified in this case that there were numerous devices for this purpose that were practicable. But can it be a valid objection to the law that at the time of the passage of the act there was doubt in the mind of the Legislature on this subject? The policy of adjusting a regulation or law to meet the conditions existing is a matter peculiarly within the province of the legislative department.
In the well-considered case of Moses v. United States, 16 D. C. App. Cas. 428, an act of Congress making it a misdemeanor for the owner, lessee, etc., of any building to issue or emit thick or dense black smoke from the smoke-stack or chimney of such building was under consideration, and among other grounds it was assailed as class legislation because the act excluded from its operation “ chimneys of buildings used exclu*98sively for private residences.” To this contention the court responded: “We can readily apprehend that there may he a very great difference between the quantity and quality of the smoke emitted from the chimneys of private dwellings, and from those connected with engines, steam boilers, and furnaces used in buildings devoted to manufacturing purposes, or in the large buildings occupied by many persons, that require an immense consumption of fuel.” The act also was restricted to stationary engines, boilers, etc., and it was insisted that the exemption of portable engines rendered it class legislation, but the court said as to that also, “The distinction made between stationary engines and portable -ones would, on its face, likewise seem not to have an unreasonable foundation. Probably the only portable engines in use would be fire engines, steam rollers, and railway locomotives. Of the two former it is sufficient to say that they are necessary agencies for the promotion and protection of paramount public interests, and are in use for such necessary periods of time and in such places only as exigencies may demand. The railway engine performs a different function, as confined to a space set apart for its use, and besides is-not-constantly engaged in diffusing its smoke from a permanent location. ’ ’
In City of Brooklyn v. Railroad, 61 N. Y. Supp. 33, 44 App. Div. 462, the act of the Legislature of New York (sec. 1, chap. 954, Laws 1895) was challenged on the ground that the act prohibiting the use of soft coal in factories, engine-rooms, or electrical stations within a.radius of four miles of the city hall in Brooklyn except for the purpose of heating or ivelding iron or steel, was class legislation. In an exhaustive opinion it was held the exception did not make the act unconstitutional. The same act was sustained in New York v. Johns-Manville Co., 89 App. Div. (Hun) 449.
In People v. Havnor, 149 N. Y. 195, an act to regulate barbering on Sunday, which prohibited a bar*99."ber to follow bis vocation on Sunday, except that in the city of New York and in Saratoga Springs such business might be carried on until one o ’clock of the afternoon of that day, was held a valid exercise of the police power, and did not violate the 14th amendment to the Federal Constitution, nor was it class legislation.
- The case of Moses v. United States, 16 D. C. App. Cas. 428, came under review in Bradley v. Dist. of Columbia, 20 D. C. App. Cas. 169, and was sustained, but it is of peculiar interest in connection with the contention that the proviso we are considering renders the act of 1901 unconstitutional as class regulation. The act of Congress made no exception in cases where an owner or manager was unable to find any appliance or device which would prevent the emission of dense smoke, but it was attempted to show in that case that there was no known appliance or device which would prevent'the emission of dense smoke, and while the court held that the evidence offered was properly excluded, it uses this •significant language: “As the operation of the furnaces in large buildings for purposes of heating, power, etc., is unquestionably necessary to the enjoyment of their ownership, any regulation with which it would be impossible to comply, by the use of any known and accessible fuel, would be beyond the power of Congress to enact. But an act of Congress in the exercise of its ordinary police power, as this appears to be on its face, is not to be lightly set aside as unreasonable and oppressive. ’ ’
. ■ In the Heitzeberg case, 141 Mo. l. c. 388, we said of the ordinance of the city under review: “It seems to us that this ordinance which makes no reasonable allowance for the regulation of this smoke, but essays in advance of any Jcnoim device for preventing it to punish all who produce it to any degree whatever, is-wholly unreasonable. ’ ’ ■
The language last quoted of course referred to the' power of a municipal corporation and not to the Gen*100eral Assembly, but broad as tbe police power of our Legislature is it is not unlimited. As said by Mr. Justice Harlan in Mugler v. Kansas, 123 U. S. l. c. 661, “It does not follow that every statute enacted ostensibly for the promotion of these ends is to be accepted as a legitimate exertion of the police powers of the State. There are, of necessity, limits beyond which legislation can not rightfully go. . . . If, therefore, a statute purporting to have been enacted to protect the public health, the public morals, or the public safety, has no real or substantial relation to those objects, or is a palpable invasion of rights secured by the fundamental law, it is the duty of the courts to so adjudge, and thereby give effect to the Constitution. ’ ’
It is too plain for argument that it was within the power of the Legislature of Missouri to enact all reasonable regulations for the suppression and prevention of the accumulation of vast quantities of dense smoke in our populous cities, and they did so by the act of 1901, but it is to their credit that they were careful to' abstain from even a semblance of oppression and an invasion of the property-right of owners and managers •of buildings to heat the same or to maintain engines and boilers for the manufacture of wares and merchandise, by providing that if there were no known practicable devices or appliances by which dense smoke so generated could be prevented, they should not be punished therefor. It was entirely competent for the Legislature to make this- exception, as it did, available not to a certain class, but to every citizen or corporation charged with a violation of the said smoke act. Indeed it would seem on the strength of the Moses case such a defense might be made even in the absence of such a proviso, and if so, certainly an express permission in ’ the statute would not render it obnoxious to the charge of class legislation,. Our conclusion is then that the proviso did not render the act unconstitutional as class legislation.
*101IV. Nor does the statute violate the 14th amendment to the Federal constitution because by implication' it omits from its operation locomotive engines and steamboats. Conceding that locomotive engines and steamboats are not included in the term of “any building, establishments or premises,” the conclusion reached by the court in Moses v. United States, 16 D. C. App. Cas. 428, that there is a reasonablé basis for the'classification of stationary engines and buildings, in one class, and portable engines, in another, appears to us to be sound and sustainable on reason and authority. Such was also the opinion of the Supreme Court of Michigan in People v. Lewis, 86 Mich. 273.
As to the further contention that brick-kilns do not fall within the application of the statute, we think it is not well taken. The act by its terms includes any building, establishment or premises from which dense smoke is so emitted or discharged” and is broad enough to include brick-kilns.
The only remaining proposition is that the Legislature could not declare the emission of dense smoke into the open air of a city of one hundred thousand inhabitants a nuisance without qualifying it by adding to it that such smoke must injure the property in the neighborhood or affect the health or interfere with the comfort of the citizens of the neighborhood. We have already ruled that the Legislature, charged with the duty of guarding the public interests and vested with a wide discretion and liberty of choice, must be presumed to have inquired into and duly considered the effect, present and prospective, of the. continual emission, constantly or at intervals, of dense smoke, upon those public interests in respect to safety, comfort and cleanliness. In State v. Whitaker, 160 Mo. l. c. 72, this court said: “It can not be questioned that in the exercise of its police power the Legislature may enact laws to protect the health and safety of our citizens by all reasonable regulations, and when a given subject is within *102that power, the extent to which it is to be exercised is within the discretion of the Legislature.”
The power to declare what is and shall be a public nuisance is clearly a legislative one, and the act in question is clearly an exercise of the police power, and . there is nothing in the act which smacks of oppression, but on the contrary it accords with the universal experience that dense smoke' emitted in a large, populous and crowded city is a nuisance, though it may not have been previously so held at common law or so declared by statute.
An act of the Legislature is not to be declared void by the courts unless the violation of the Constitution is so manifest as to leave no room for reasonable doubt. [State v. Layton, 160 Mo. l. c. 488.]
This contention as the others must be held untenable.
Finding no error in the record the judgment of the Court of Criminal Correction is affirmed.
All concur, except Burgess, J., absent.
