WELCH v. SWASEY ET AL., AS THE BOARD OF APPEAL FROM THE BUILDING COMMISSIONER OF THE CITY OF BOSTON.
ERROR TO THE SUPREME • JUDICIAL COURT OF THE STATE OF MASSACHUSETTS.
No. 153.
Argued April 15, 16, 1909.
Decided May 17, 1909.
Whether a state statute is illegal because it delegates legislative power •to a commission does not raise á Federal question.
, A statute limiting the height of buildings cannot be justified under the ■. police power unless it has some fair tendency to accomplish, or aid in the accomplishment of, some purpose for which that power can be ■ used; if the means employed, pursuant to thé statute, have no real substantial relation to such purpose, or if the statute is arbitrary, unreasonable and beyond the necessities of the case, it. is invalid as taking property without due process of law..
In determining the validity of a state statute affecting height of buildings, local conditions must be considered; and, while.the judgmept of the highest court may not be conclusive, it is entitled to the greatest respect, and will not be interfered with unless- clearly wrong.'
Where the highest court, of the State has held "that there is reasonable ground fo.r classification between the commercial and residential portions of a city as to the height of buildings, based on practical and not «esthetic grounds, and that the-police power is not to be exercised ' for merely «esthetic' purposes, this court will not hold that such a • statute, -upheld' by the state court,, prescribing different'heights in different sections of the city is- unconstitutional as discriminating against, and denying equal protection of ithe law to, the owners of property, in the district, where the lower height is prescribed;
Where'there is -justification for the- enactment - óf a police statute limiting the height of buildings in a particular district, an owner of ■ property in thgt district -is not entitled to compensation for the reasonable interference with his property by the statute.
Chapters'333 of the acts pf 1904 and 383 of the acts of 1905’of Massachusetts, limiting the heights of büildings in Boston and prescribing different heights in different sections of the city are', in view of the decision of the highfest court of Massachusetts holding that the.discrimination is based upon reasonable grounds, a proper exercise of the police power of the State, and are not unconstitutional under the equal protection and due process clauses of the Fourteenth Amendment.' '
193 Massachusetts, 364, affirmed.
The plaintiff in error duly applied to the justices of the Supreme Judicial Court of the State of Massachusetts for a mandamus against the defendants, who constitute a board of appeal from the Building Commissioner of the City of Boston, to compel the defendants to issue a permit to him to build on his lot on the corner of Arlington and Marlborough streets, in that city. The application'was referred by the justice presiding. to tlje full court, and was by it denied (193 Massachusetts, 364), and the plaintiff has brought the case here by writ of error.
The action of defendants in refusing the permit was based on the statutes of Massachusetts, chap. 333 of the acts of 1904, and chap. 383 of the acts^of 1905. The two acts are set forth in the margin. The reason for the refusal to grant the building permit was because the building site for the proposed building, was situated in one of the districts B, as created under the-provisions of the acts mentioned, in which! districts the height of the buildings is limited to eighty, or, in some cases, to one hundred feet, while the height of buildings in districts A is limited to one hundred and twenty-five feet. The height of thé building which plaintiff in error proposed to build and for which he asked the building permit was stated by him in his application therefor to be one hundred and twenty-four feet, six inches.
The designation of what parts in districts B and upon what conditions a building could be therein erected more than eighty while not more than -one hundred feet high was to be made by á commission, as provided for in the act of 1905, and the commission duly carried out the provisions of the act in that respe'ct. The sole reason for refusing the permit was on account of the proposed height of thé building, being greater than the law allowed.
The plaintiff in error contended that the defendants were not justified in their refusal to grant the permit, because the statutes upon which their refusal was based were unconstitutional and void, but he conceded that if they were valid the defendants were justified in their refusal.
The court, while deciding that mandamus was a proper remedy, held that the statutes and the reports of the commissions thereunder were constitutional.
Mr. Burton Edward Eames) with whom Mr. Charles H. Tyler and Mr. Owen D. Young were .on the brief, for plaintiff in error:
The first point in the argument of the plaintiff in error is that, the purpose of these acts is not within the sphere of purposes for which the police power may lawfully be exercised;
The court will look to the-real purpose of the statute. Watertown v. Mayo, 109 Massachusetts, 315, 319; Austin v. Murray, 16 Pick. 121, 126; State v. Redmon, 134 Wisconsin, 89, 107; Mugler v. Kansas, 123 U. S. 623, 661; Brimmer v. Rebman, 138 U. S. 78, 82; Yick Wo v. Hopkins, 118 U. S. 356; Soon Hing v. Crowley, 113 U. S. 703, 710; People v. Compagnie Generate Transatlantique, 107 U. S. 59, 63; Henderson v. Mayor of New York, 92 U. S. 259; Cal. Reduction Co. v. Sanitary. Wks., 199 U. S. 306; Health Dept. v. Rector, 145 N. Y. 32, 40; Matter of Jacobs, 98 N. Y. 98, 110; Farist Steel Co. v. Bridgeport, 60 Connecticut, 278, 292; Priewe v. Wisconsin &c. Imp. Co., 103 Wisconsin, 537, 549.
• In determining what is the real purpose of the statute, the court will consider the history of the times and the circumstances leading up to its enactment. Holy Trinity Church v. United States, 143 U. S. 457.
-The purpose-may also be inferred from the terms of the act itself. Lochner v. New York, 198 U. S. 45; Talbot v. Hudson, 16 Gray, 417, 420; Simpson v. Story, 145 Massachusetts, 497, 498; Pollock v. Farmers L. & T. Co., 157 U. S. 429, 558 et seq.; Farist Steel Co. v. Bridgeport, 60 Connecticut, 278.
The real purpose of these acts was aesthetic.
-This appears from the circumstances under which they were, passed. ' Contemporaneous statutes and contemporaneous litigation,: tend to the conclusion that they were aimed not at dangers to the public health, safety, morals or well-being, but' that they were designed purely for purposes Which may be ealled aesthetic', to preserve architectural.symmetry and regular sky-lines.
The -first act was passed in the legislative session of 1903-1904, very shortly after the.decisions by the Supreme Judicial Court of Massachusetts and by this .court sustaining the statutes' which limited the height of buildings in the' vicinity of Copley Square and upon Beacon Hill as lawful exercises of the power of eminent domain. Attorney-General v. Williams, 174 Massachusetts, 476 (October, 1899); Parker v. Commonwealth, 178 Massachusetts, 199 (March, 1901); Attorney-General v. Williams, 178 Massachusetts, 330 (March, 1901); Williams v. Parker, 188 U. S. 491 (February, 1903).
The police power cannot properly.'be exercised for an aesthetic • purpose.
Although property may be taken by right of eminent domain for aesthetic purposes, — Higginson v. Nahant, 11 Allen, 530; Attorney-General v. Williams, 174 Massachusetts, 476,—that purpose is not sufficient to warrant the exercise of the police power in such manner as to interfere with the use of property. Commonwealth v. Boston Ad. Co., 188 Massachusetts, 348; St. Louis v. Hill, 116 Missouri, 527; St. Louis v. Dorr, 145 Missouri, 466; People v. Green, 85 App. Div. (N. Y.) 400; Bostock v. Sams, 95 Maryland, 400; Posting Sign Co. v. Atlantic City, 71 N. J. L. 72; Passaic v. Patterson Bill Post. Co., 72 N. J. L. 285; Chicago v. Gunning System, 214 Illinois, 628; Article on “Public Æsthetics,” by Wilbur Larremore, in Harvard Law Review, November, 1906, p. 42.
The infringement upon rights of property involved in these -acts is unreasonable.
The principle of reasonableness is a principle of proportionateness. The. courts appear to have adopted the principle that the legislative acts under the police power, when affecting private rights, must have “ some 'fair and reasonable relation of means to • end which courts can see and • admit the force of,” and .that the infringement'of rights must bear a reasonable relation to the public necessity, i. e., the measure must be proportionate to the end in view. Ex parte Whitwell, 98 California, 73; State v. Speyer, 67 Vermont, 502; Commonwealth v. Tewksbury, 11 Met. 55, 57; Cooley on Constitutional Limitations (7th ed.), 878; Miller v. Horton, 152 Massachu setts, 540, 547; State v. Ashbrook, 154 Missouri, 375; People v. Gillson, 109 N. Y. 389, 403; Health Department v. Rector, 145 N. Y. 32; Matter of Jacobs, 98 N. Y. 98, 110; Mugler v. Kansas, 123 U. S. 623; Chicago &c. Ry. v. Drainage Commissioners, 200 U. S. 561, 593; Railway Co. v. Husen, 95 U. S. 465; Sawyer v. Davis, 136 Massachusetts, 239; Rideout v. Knox, 148 Massachusetts, 368.
Any regulation which deprives any person of a profitable’ use of his property constitutes a taking of property, and entitles him'under the Constitution to compensation, unless the invasion of rights is. so slight as to permit the regulation to be justified under the police power. Pumpelly v. Green Bay Co., 13 Wall. 166, 179; United States v. Lynah, 188 U. S. 445; Sweet v. Rechel, 159 U. S. 380, 399; Eaton v. Boston &c. R. R., 51 N. H. 504; Bent v. Emery, 173 Massachusetts, 495; Grand Rapids v. Jarvis, 30 Michigan, 308, 320, 321; Matter of Jacobs, 98 N. Y. 98, 105, 106; Edwards v. Bruorton, 184 Massachusetts, 529, 532, 533; Holmes, J., in Miller v. Horton, 152 Massachusetts, 540, 547.
The legislature of Massachusetts in the previous statutes limiting the height of buildings about Copley Square in Boston to the height, of ninety feet, and on Beacon Hill, in the vicinity of the State House, in Boston, to a 'height, of-seventy feet, recognized that such á regulation involved a taking of property,. Stats. 1898,'ch.;.452;.Stats. 1899, ch. 457, and the Supreme Court of 'Massachusetts, in the decisions sústaining. those statutes as exercises of the power of eminent .domain, likewise recognized this fact. Attorney-General v. Williams, 174 Massachusetts, 476; Parker v. Commonwealth, 178 Massachusetts, 199; Attorney-General v. Williams, 178 Massachusetts, 330.
Even if the statutes were enacted for some object properly within the scope of the police power, they involve an invasion of private.rights which is entirely disproportionate to any'of the objects which the legislature might .'properly have had in' view. ,
The only objects, aside from' the Eesthetic, which it, is at all conceivable might have been in view of the legislature, are ‘the public health or safety, and no public necessity existed for either of those objects sufficient to justify the\ measures.
■ The experience of othér cities with buildings much higher .than anyone has yet desired to build 'in Boston, and much higher than the limits fixed by these statutes, goes very strongly to show that the danger of injüry to health and the' danger from fire where tall buildings aré properly constructed are very slight.
■Even if the' object or purpose of these acts was within the legitimate sphere of purposes.permissible to the police power, yet the classification adopted has-no proper relation to either, of the possible ostensible -objects, but is arbitrary and unreasonable. . The constitutional provision for equal protection of the laws means that all persons are to be treated alike. It ■contemplates the right of the legislature to make reasonable classifications, and the protection given by the law is considered equal if all persons within the classes thus established are treated alike under-like' circumstances and conditions. Missouri v. Lewis, 101 U. S. 22; Magoun v. Illinois Savings Bank, 170 U. S, 283, 293; Barbier v. Connolly, 113 U. S. 27, 31; Hayes v. Missouri, 120 U. S. 68, 71.
The classification adopted must be a reasonable 'one, with reference to the purpose-for which the statute is enacted; it cannot be arbitrary. Gulf &c. Ry. v. Ellis, 165 U. S. 150, 159, 165; Connolly v. Union Sewer Pipe Co., 184 U. S. 540, 560; Atchison &c. R. R. v. Mathews, 174 U. S. 96, 104; Heath & Milligan v. Worst, 207 U. S. 338.
So far as it may be desirable, to dp so, the court will take judicial notice of facts of common .knowledge, of the location of the lines drawn by the commission, of the situation of various streets, and of the character of the various districts- and’localities of the city. Brimmer v. Rebman, 138 U. S. 78; Minnesota v. Barber, 136 U. S. 313, 321; Jacobson v. Massachusetts, 197 U. S. 11, 23; Muller v. Oregon, 208 U. S. 412, 421; Siegbert v. Stiles, 39 Wisconsin, 533; The Montello, 11 Wall. 411; Gardner v. Eberhart, 82 Illinois, 316; Prince v. Crocker, 166 Massachusetts, 347.
■The situtation and character .of the various districts and localities of the- City of Boston being matters of common knowledge,' of which the Supreme Judicial Court of Massachusetts would and did take notice, this coprt is authorized to do likewise as, upon writ of error, it takes judicial notice of all matters which were matters of law in the state court. -By analogy, therefore, this court should notice judicially all matters not required to be proved, as facts in the state, court, in-eluding matters of judicial notice. Matters of judicial notice are matters-of. law.
.The.classification.attempted in these statutes is arbitrary and is not considered, with a purpose to safeguard either the public health or the . public safety. -
They are special laws, applying only to Boston, and while a reasonable classification of. cities may. be made, it must be based upon some real differencé with', reference to the purposes of the act. Tenement House Department v. Moeschen, 179 N. Y. 325; Watertown v. Mayo, 109 Massachusetts, 315; State v. Hammer, 42 N. J. Law, 435, 440; Bessette v. People, 193 Illinois 334.
The classification attempted within the City of Boston is "not bated upon reasonable grounds. Yick Wo v. Hopkins, 118 U. S. 356, 368; Newton v. Belger, 143 Massachusetts, 598.
The statute gives exceptional rights to property holders in district B whose, property is situated within fifty feet of the division line established, provided theyalso own land on ihe other side of the división-linó]
It,is provided that the height of buildings in district B above, eighty .feet shall depend upon the width of the building upon the street.
The statutes, create exceptions in favor .of certain occupations. Connolly v. Union Sewer Pipe Co., 184 U. S. 540.
Mr. Thomas M. Babson for defendant in error:
The first question is whether an act limiting the height of buildings is . constitutional at all7 The statute was .enacted, according to the decision of the Supreme Judicial Court of the State, in behalf of the public health and safety, and the Su'preme Court of the United States will not strike it down as an unconstitutional interference with private, property unless it can plainly see that it has nó real and substantial relation to those objects.and is a mere arbitrary attack upon'the owners of land.- Slaughter-House Cases, 16 Wall. 36; Bartemeyer v. Iowa, 18 Wall. 129; Munn v. Illinois, 94 U. S. 113; Beer Co. v. Massachusetts, 97 U. S. 25; Barbier v. Connolly, 113 U. S. 27; Mugler v. Kansas, 123 U. S. 623; Powell v. Pennsylvania, 127 U.

S. 311; Hudson County Water Co. v. McCarter, 209 U. S. 349.
The right of the State to regulate the construction of buildings'has been-recognized and exercised ever since the population of our cities became dense enough to make regulation desirable and necessary for' the protection of the inhabitants from fire and disease. Ex parte Fiske, 72 California, 125; Baumgartner v. Hasty, 100 Indiana, 575; Mt. Vernon First National Bank v. Sarlls, 129 Indiana, 201; Wadleigh v. Gilman, 12 Maine, 403; Easton v.

Until the introduction' within recent years of steel frame construction, very tall buildings were not practicable, and it is only lately that there has. been any need of legislation restricting the height of building^, for the natural difficulties were, formerly sufficient protection to the public.
In determining' whether a state statute is aimed and adapted to promote the public welfare, this court will hesitate to overturn a decision of. the highest court of the State.. The validity of the statute may depend on-certain facts, general, notorious and acknowledged within the State, and with which the state courts may be assumed to be exceptionally familiar. They understand the situation ydiich led to the demand for thé enactment .of the statute, and they appreciate the disastrous results which in all probability would, flow from a denial of its validity. Clark v. Nash, 198 U. S. 361; Strickley v. Highland Boy Mining Co., 200 U. S. 527; Bacon v. Walker, 204 U. S. 311.
■ What is a reasonable - regulation in one city- might be unreasonable ,in another. The. Massachusetts legislature has deemed this restriction wise, ’and its highest court has called it reasonable; their decision should carry great’ weight. ■.
Plaintiffs in error are not entitled to compensation because-there was no taking of this property. . This court has never accepted the: fanciful doctrine that' whatever decreases the Value of land is'the.taking, pro tanto, of the owner’s property and so Unconstitutional unless he is paid fór the damage, but has steadfastly adhered to the older and' sounder rule that land is not taken unless it is physically entered upon or the owner substantially deprived of the ben'eficial use. Smith v. Washington, 20 How. 135; Transportation Company v. Chicago, 99 U. S. 635; Osborne v. Missouri Pacific R. R. Co., 147 U. S. 248; Gibson v. United States, 166 U. S. 275; Meyer v. Richmond, 172 U. S. 95; Sharp v. United States, 191 U. S. 341; Bedford v. United States, 192 U. S. 217.
Regulations and restrictions -upon the use of real propérty havé "been imposed which limit its úse and impair its value more severely than those' in the case at bar without giving rise to any constitutional obligation to compénsate the owner.

Opinion:
Mr. Justice Peckham,
after making the foregoing statement, delivered the opinion of the court.
The ground of objection of plaintiff in error to this legisla-' tion is that the statutes unduly and unreasonably infringe upon his constitutional rights, (a) .As to taking of property without compensation; (6) As to denial of equal protection of the laws.
- Plaintiff in error refers to the existence óf a general law in Massachusetts applicable to every city therein, limiting the height of all buildings to. one hundred and twenty-five feet above the grade of the street (acts of 1891, ch. 355), and states that he does hot attack the validity of that act in any respect, but concedes that' it is constitutional and valid.- See also on same subject acts of 1892, ch. 419,- § 25, making such- limitar tion as to the City of Boston. His objection is directed to the particular statutes, because they provide for a much lower limit in certain parts of the City of Boston, to be designated by a commission, and because á general restriction .of height as' low as eighty or one hundred feet over any substantial portion of the city is, as he, contends,'an .unreasonable infringement upon his rights of property; also that.the;application of.those limits to districts B, which comprise the greater part of the City of'Boston, leaving thg general one hundred and twenty-five feet limit in force in those portions, of the city,'which the commission should designate (being the commercial districts), is an unreasonable and arbitrary denial of equal rights, to the- plaintiff in-error and others in like situation.
Stating his objections more in detail, the plaintiff in error contends that-the purposes of the acts are not such as justify the exercise .Of what is -termed the police power, because, in .fact,, their real-purpose was of an' aesthetic nature, designed purely to preserve architectural symmetry and regular skylines, and that such power cannot be exercised for such a purpose.- It is' further objected that the. infringement upon property rights by these- acts is unreasonable and dispróportioned to any public-necessity, and also that the distinction between one hundred! and twenty-five feet for the height of buildings in the commercial districts described in the ácts, and eighty to one hundred feet in certain other or so-called residential districts, is wholly unjustifiable and .arbitrary,- having no weljfounded reason for such distinction, and is without the least reference to the public safety, -as. from fire, and inefficient-as means to any appropriate end,to be attained by such laws.
In relation to these óbjéctions the counsel' for the plaintiff in error, in presenting -his case at bar, made a very- clear and able argument. ,
' Undér the concession'of counsel, that the law limiting the height of' buildings to one hundred and twenty-five feet is valid, we have-to deal only, with the.question of the validity of the provisions stated in these statutes and in the conditions provided for by .the commissions, limiting the. 'height in districts B betwéen eighty and one hundred feet.
We do not understand that the plaintiff in'error makes the objection of illegality arising from an alleged-delegation Of legislative power to the commissions provided for by the statutes. At all events, it does not raise a Federal question: The state court-holds'that. kind' of legislation to be valid under the state constitution and this :court-will follow its determination upon that question-
Wé come, then, to an examination of the question whether these statutes with reference tq limitations on height between eighty and one hundred feet and in no case greater than one hundred feet aré valid. Theré is here a discrimination or clas^ sification between sections of the city, one of which, the business or .commercial part, has a limitation of one hundred and twenty-five feet, .and the other, used for residential purposes, has apermitted héight of buildings from eighty to one hundred feet.
' The statutes have beén passed under the exercise of so-. .called- police power, and- they must haye some fair tendency to accomplish, or aid in the accomplishment of some purpose, for -which,the legislature may. use the power. If the statutes are not of that kind, thén their passage cannot be justified under .that power. These principles have been so frequently decided as not1 to require the .citation of many authorities. If the means employed, pursuant to the statute, have no real, substantial relation to a public object which government can accomplish; if the statutes are -arbitrary and Unreasonable and' beyond the necessities of the case; the courts'will declare their -invalidity. The following are a few of the many -cases upon this subject: Mugler v. Kansas, 123 U. S. 623, 661; Minnesota v. Barber, 136 U.S. 313, 320; Jacobson v. Massachusetts, 197 U. S. 11, 28; Lochner v. New York, 198 U. S. 45, 57; Chicago Railway Company v. Drainage Commissioners, 200 U. S. 561, 593.
•' In passing upon questions of this character as to the válidity and reasonableness of-a discrimination or, classification in re,lation to limitations as'to height of buildings in-a large city, the matter of locality assumes an important aspect. The particular. circumstances prevailing at the place or in the. State where the law is to become operative; whether the statute is really adapted, regard being had to all the different and material facts, to-bring about the.results desired from its passage; .whether it is well Calculated to promote, the general and'public welfare, are all matters which the state court is familiar with, but adike' familiarity cannot be ascribed to this court, assum ing judicial notice', may be taken of what is or ought to be generally known: For such reason this court, in cases of this kind, feels .the greatest reluctance in interfering with the well-considered judgments of the courts of a State whose people are to-be affected by the operation of the "law. The highest court of the State, in.which statutes of ¡the kind under consideration áre passed -is more familiar with the particular, causes which, led to their passage - (although they may bé of a public nature) .and with-the general situation'surrounding the subject-matter of the legislation than this court can'póssibly be.- We do not, of course, intend to-say that under-such circumstances the judgment of the state court upon the question will be regarded as conclusive, but simply that it is entitled to'the very greatest respect, and will only be interfered-with, in cases of this kind, where the decision is, in our judgment, plainly-wrong. In this case-the Supreme Judicial Court of the State holds the legislation valid, and -that there is'a fair reason for the discriminar tion between the-height of buildings in the residential as compared with the commercial districts. That court has also held that regulations in regard to the height of buildings, and in regard to their mode-of construction-in cities, made by legislative enactment's for the safety, comfort or convenience of the people and for the benefit of property owners generally, are valid. Attorney-General v. Williams, 174 Massachusetts, 476. We, concur in that view, assuming, of course, that the height and conditions, provided for can -be plainly seen to be not unreasonable or inappropriate.-
. In relation to thé discrimination or classification made between the commerciál and the residential'portion of the city, the state' court holds in this case that there is reasonable ground therefor, in the very great valué of'the land and the demand for' space in those parts of Boston where a greater number of buildings áre used for the purposes of business or commercially'than'where;the buildings are'situated'-in the residential portion of 'the city, and-where no such' reasons exist for high buildings. While so deciding the court cited, with approval, Commonwealth v. Boston Advertising Company, 188 Massachusetts, 348, which holds that the police power cannot be .exercised for a merely'testhetic purpose. The court distinguishes between the two cases and sustains the present statutes. As to the condition adopted by the commission for permitting the erection, in either of the districts B, that is, the residential portion', of buildings of oyer eighty feet,, but never more than one hundred, that the width, on each and every public street on which the building-stands shall be at least one-half its height, the court refuses to hold that Such .condition was entirely for aesthetic reasons. The Chief Justice said: "We conceive that the safety of adjoining buildings, in view of the risk of the falling of wálls after a fire, may have entered-into the purpose of the commissioners. We are of opinion that the statutes and orders of the commissioners are constitutional."'
We . are not prepared to hold that this limitation of eighty to one hundred feet, while in fact a discrimination or classification, is so unreasonable that it deprives the owner of the property, of its profitable use without justification, and that-he is therefore entitled under the Constitution to compensation for such invasion of his rights. The discrimination thus: made is, as we think, reasonable, and is justified by the police power.
. It might well be supposed that taller buildings in the commercial- section of the city might be less dangerous in case of fire than in the residential portion. This court is not familiar with the actual facts, but it may be that in this limited commercial area fhe high buildings are generally of fireproof construction ; that the fire engines are more numerous and much closer togéther than in the residential portion, and that an unlimited supply of salt water cambe more readily introduced from the harbor into the pipes, and that few women or. children are .found there in the daytime and very few people sleep there at night. And there may in -the residential part be more wooden buildings, the fire apparatus may be more widely ' scattered and .so situated that it would 'be more difficult to obtain the necessary amount of; water, as the residence quar ters are more, remote from the water front, and that many women and children spend the day in .that!section, and the.' opinion is not sprained that an undiscovered fire at night might cause great loss of life in a very high apartmfent house in that district. These áre matters which it must be presumed were known by the legislature, and whether or not such were the facts was a question, among others, for the legislature to determine. They are asserted as facts in -the brief of the' counsel for the City of Boston. If they are, it would seem that, ample justification is therein found for the passage of the statutes; and that the plaintiff in error is not entitled tp compensation for the reasonable interference -with his, property rights by the statutes. That in addition to these sufficient facts, considerations of an ¿esthetic nature also entered into the reasons for,their passage, would not invalidate them. Under these circumstances there .is no unreasonable interference with the rights of property of the' plaintiff in error, nor do the statutes deprive him of the equal protection of the laws. The reasons contained in the opinion of the state court are in our view sufficient to justify their 'enactment. The judgment is therefore .
Affirmed.
