— This action was brought to recover $194.80 alleged to be due the appellant, Boise City, for money expended in the construction of a certain bridge across the respondent’s water ditch, where said ditch crosses Fifth street of said city. The respondent answered, and the cause was heard upon an *782agreed stipulation of facte. Judgment was entered in favor of the respondent. A motion for a new trial was interposed by the appellant and overruled by the court. This appeal is from the judgment and the order denying the motion for a new trial.
Several errors are assigned, all to the effect that the finding of facts is not supported by the evidence. It is admitted in the agreed stipulation of facts: That the respondent, the Boise Bapid Transit Company, is a corporation duly organized and acting under the laws of the state of Idaho, and has been such since the thirteenth day of August, 1890, and since that date has been the owner of, and has operated and controlled, the water ditch referred to in the complaint. That the water running through said ditch is owned and used by the respondent for the purpose of carrying on and operating its street railway in said Boise City. That during the year 1863, the said water ditch was constructed by respondent’s predecessors in. interest, and has during.all of the time since its construction been running in its present course. That a patent from the United States to the lands over which said ditch extends was issued to the mayor of Boise City, May 2, 1870. That on the eleventh day of January, 1866, the appellant was duly incorporated as a municipal corporation under the name of “Boise City,” and at that time said Fifth street was laid out as a street and public highway, and has ever since been used as a street and public highway of said city, and was within the corporate limits thereof, but that said street was not extended farther south than across Front street of said city, until the Davis addition became a part of said city, in the year 1892. That said ditch and said Fifth street, and the other streets referred to in said complaint, to wit, Seventh, Front, and Eighth streets, intersect and cross each other. That on the twentieth day of July, 1899, a certain bridge across said ditch, located where said ditch and Fifth street intersect each other, became and was out of repair and dangerous, and wholly unsafe and insufficient for public travel. That on the twenty-fifth day of July, 1899, the street commissioner served legal notice upon the respondent of the dangerous and unsafe condition of said *783bridge, and notified respondent to repair the same. That respondent failed, neglected and refused to do so. Thereafter, on August 3, 1899, said city constructed a bridge across said ditch at said place at its own expense, of $194.80. That said respondent has been requested to pay said sum, but has failed and refused to do so. That since said notice was served on respondent, it has repaired a bridge over said ditch where said ditch runs across said Eighth street. The notice above referred to also notified respondent of the unsafe and dangerous condition of the last-mentioned bridge, and notified respondent to repair, the same. That in the year 1894, appellant notified respondent to construct a bridge across said ditch where it crosses said Fifth street, but that respondent failed and refused to do so, and thereafter appellant constructed said bridge at his own expense, and that no proceedings have been had to recover from respondent the sum so expended. That respondent has not built or repaired or maintained said bridge in any way or manner. That on the twelfth day of September, 1890, the respondent received a deed of conveyance whereby said ditch was conveyed to it. Under the foregoing facts, counsel for respondent contend that, as its predecessors constructed said ditch long prior to the time that said Fifth street was platted or dedicated to the public as a street or highway, it is the duty of the city to bridge said ditch at its own expense, if the public safety and convenience require that to be done, and that said street was dedicated to the use of the public, subject to the pre-existing rights of respondent and its predecessors, and for that reason the city must bridge said ditch, if the public necessities require it.
The only question in the ease is, Upon whom devolves the duty of constructing the bridge over respondent’s ditch across Fifth street? The record shows that said ditch must be bridged at said crossing, as said ditch is shown to be an obstruction to the free and customary use of said street by the public. Said obstruction is a public nuisance. Said ditch at said point may not have been a public nuisance at the time of its construction, but conditions have changed since then. What ivas noth*784ing but wild land, covered with sagebrush, at the date of the construction of said ditch, has became a thickly settled part of said Boise City; and said Fifth street, where said ditch crosses it, is very much used by the public. Said ditch, unbridged, would be a great obstruction to the free use of said street, and was a public nuisance.
Subdivision 8 of section 3 of the charter of Boise City, as amended by the laws of 1899 (page 311), provides, among other things, that the mayor and common council shall have full power and authority within Boise City to prevent and abate nuisances, and generally to determine and declare what shall he deemed nuisances, and to provide for the removal and abatement thereof. The record shows that said bridge across said street was in a dangerous and unsafe condition; that said ditch was maintained by respondent in that condition; that the proper authority of said city notified respondent of that fact, and to repair said bridge, which it refused to do. The maintenance of said bridge in its then unsafe condition obstructed the free use of said street by the public, and wa’s clearly a public nuisance, as defined by sections 3620, 3621 of the Revised Statutes. While it appears from the record that said ditch was constructed in its present location prior to the time said Fifth street was laid out across it and dedicated to public use, it is also true that one James H. Slater and his associates, who were owners of said ditch in 1866,.made application to the territorial legislature of Idaho, to grant them a right of way for said ditch through Boise City, which application was granted by an act entitled “An act to grant James II. Slater and his associates right of way for a water canal or ditch in Ada county,” approved January 11 A. D. 1866. (See Laws 3d Sess., p. 239.) The first section of said act grants said Slater and his associates a right of way for a canal or ditch, of a capacity not to exceed three thousand inches, for a distance of three miles from a point then marked as the head of said ditch, on the ranch of Mooney & Co.; thence through Front street, in Boise City; and thence down the valley of Boise river. The second section provides that the owners of such ditch may sell the water conducted by said ditch for *785milling, irrigating or other useful purposes.. The third section provides that said grant shall continue ten years from and after the approval of said aot. The fourth section provides, in case any parties owning grounds over which the said ditch may run ¡sustain damage thereby, the manner and method of assessing such damages. This act, taken as a whole, indicates that said ditch was not constructed, or at least completed, when said act was passed. But it is a stipulated fact, that said ditch was constructed in 1863, and this suit must be decided on the facts as stipulated. Some stress is laid on the fact that the third section of said act provides that the grant of said right of way should continue for ten years. That fact, however, cuts no figure in the determination of this case. Conceding that the respondent and its predecessors in interest had a perpetual right of way, acquired prior to the incorporation of said city, and prior to the extension of said Fifth street over and across said ditch and right of way, said right of way and ditch were acquired, constructed, procured, purchased, and held subject to the restriction that said ditch must be so used as not to injure the public. Every right, from absolute ownership of property to a mere license or easement, is held subject to the rule that it shall be so used and exercised as not to injure others. And the rule is well settled that, when a city extends its limits, offensive trades and businesses must be removed beyond the immediate neighborhood of residences of citizens. (City of Kansas v. McAleer, 31 Mo. App. 433; Wier's Appeal, 74 Pa. St. 230; Coates v. Mayor etc., 7 Cow. 585.) Though at the same time said ditch was constructed there may have been no necessity for bridging the same, the owners were bound to know that said Boise City, through which it ran, might become a populous city, and in such case said ditch would become a public nuisance unless it was bridged and covered in places so as to protect the public from danger and injury, and to give the public the free use of streets. And when that period should arrive, as it is shown by the record it has, the owners thereof would be amenable to the laws for the suppression of nuisances. The respondent must so conduct its said ditch business, and so bridge *786and place guards about said ditch, as to■ protect the public from danger and injury therefrom, at its own expense. If it does not do so, it comes in conflict with the law for the suppression or removal of nuisances, and must yield to it. The police power of Boise City is amply sufficient to compel the inhabitants or property owners thereof to so conduct their affairs and use their property in a manner as not to be injurious to health, or indecent or offensive to the senses, and not to obstruct the free passage or use of streets in the customary manner.
But it is argued by the respondent that the act of March 15, 1899, amending sections 935, 968 of the Revised Statutes (Sess. Acts 1899, p. 405), exempts respondent from maintaining bridges over its said ditch, where it runs over the public, highway, in repair. To this argument we reply that said act is prospective in its operation, and does not apply to ditches and canals that had been constructed across public highways prior to the time said act went into effect. It is doubtful whether the legislature has power to take away from the public, by legislation, a right which had vested in the public prior to such legislation.
The conclusion we reach is that it was the duty of respondent to build said bridge, and as it failed and neglected to do so, and the city built it, the city may recover the cost of building the same from respondent. The judgment is reversed and the cause remanded, with instructions to enter judgment in favor of the appellant, as prayed for in the complaint. Costs of this appeal are awarded to the appellant.
