¶1— The petitioner, John Linehan, was convicted in the Police Judge’s Court of the city and county of San Francisco, upon a complaint charging him with keeping more than-two cows within certain limits in said city and county, in violation of order No. 1587 of the board of supervisors of said city and county, as amended by order No. 1705. A fine was imposed upon defendant, and in default of payment thereof he was adjudged to be imprisoned, etc. He appealed to the Superior Court, where the judgment was affirmed, and upon the return of the remittitur he was committed in default of payment, and being in custody sues out this writ.
¶2Section 1 of said order is as follows:—
¶3“ Sec. 1. Any person violating any of the provisions of this order shall be deemed guilty of a misdemeanor, and be punished by a fine not exceeding one thousand dollars, or imprisonment not exceeding six months, or by both such fine and imprisonment.”
¶4Section 63, as amended, reads as follows: —
¶5“ Sec. 63. No person or persons shall keep or cause to be kept any swine whatsoever, nor more than two cows, *115within that portion of the city and county of San Francisco bounded as follows: Commencing at the intersection of Lombard Street with the waters of the bay, thence along Lombard Street to Broderick Street, thence southerly along Broderick Street to Waller Street, thence easterly along Waller Street to Devisadero Street, thence southerly on Devisadero Street to Eidlev Street, thence easterly on Eidley Street to Castro Street, thence southerly on Castro Street to Seventeenth Street, thence westerly on Seventeenth Street to Douglass Street, thence southerly on Douglass Street to Twenty-sixth Street, thence easterly on Twenty-sixth Street to Harrison Street, thence northerly along Harrison Street to Channel Street, thence along Channel Street to the waters of the bay, thence following the water-front and waters of the bay to the point of commencement.”
¶6Under our constitution, “ any county, city, town, or township may make and enforce within its limits all such local, police, sanitary, and other regulations as are not in conflict with general laws.” (Art. 11, sec. 11.)
¶7By an act of the legislature of the state of California, entitled “An act to confer further powers upon the board of supervisors of the city and county of San Francisco,” approved April 25, 1863, it is provided that the board of supervisors shall have power, by regulation or order, among other things,—
¶8“ To authorize and direct the summary abatement of nuisances; to make all regulations which may be necessary or expedient for the preservation of public health and the prevention of contagious diseases.....To prohibit and suppress or exclude from certain limits or to regulate all occupations, houses, etc., .... which are against good morals, contrary to public order and decency, or dangerous to the public safety.”
¶9Here, then, we have as authority for the proceedings of which petitioner complains: —
¶101 The provision of the constitution authorizing the *116city and county to make and enforce such local, police, sanitary, and other regulations as are not in conflict with general laws.
¶112. The statute from which we have quoted, expressly authorizing the hoard of supervisors to regulate or exclude occupations, etc., detrimental to good morals or contrary to order, etc., or dangerous to the public safety; and,—
¶123. The order or ordinance against keeping more than two cows within certain portions of the city, for the violation of which defendant was convicted.
¶13Subject to constitutional limitations, legislative authority extends to the suppression or regulation of those things which are hurtful to the general good, and as a general rule, the law-making power will be deemed the exclusive judge of what is or is not hurtful. (Ex parte Andrews, 18 Cal. 679.)
¶14The necessity of legislation to restrict the unlimited herding of swine and cows in thickly populated districts is too. apparent to need argument.
¶15Keeping swine or cows is, or may be, an occupation; and within certain limits, may be detrimental to health .and dangerous to the public safety.
¶16We suppose these animals are kept in large numbers, not for the company, but for the profit they afford, and when so kept, it is a business, an occupation, equally with .any other.
¶17There is no constitutional question involved in this case which has not been in effect and principle passed upon heretofore by this court. (Ex parte Heilbron, 65 Cal. 609; Ex parte Shrader, 33 Cal. 279; Ex parte Smith & Keating, 38 Cal. 702; Ex parte Casinello, 62 Cal. 538; Johnson v. Simonton, 43 Cal. 242; Ex parte Andrews, 18 Cal. 679.)
¶18We deem the reasoning in these cases conclusive of the several positions assumed on behalf of the petitioner here, and are of opinion the prayer of the petition should *117be denied, and the petitioner remanded to the custody of the chief of police.
¶19Belcher, C. 0., and Foote, 0., concurred.
¶20— For the reasons given in the foregoing opinion, the petitioner is remanded.
