*369Opinion by
Mr. Chief Justice McBride.1. This case involves an examination of the whole law respecting the liability of city officers for injuries arising from the defective condition of streets as well as a consideration of the responsibilities imposed upon the particular officers here impleaded by virtue of the provisions of the city charter. Before considering these we will pass upon a preliminary question raised by plaintiff regarding the sufficiency of the appeal. As before stated, the City of Portland at the conclusion of plaintiff’s testimony moved for a nonsuit, which was granted although no formal judgment of nonsuit appears to have been entered. Thereafter it disappeared from the case. No appeal was taken by plaintiff from the allowance of the motion, and it may well be questioned whether any appeal therefrom could have been taken until the entry of a formal judgment of nonsuit. However, that question is not before us. The notice of appeal by these defendants was not served upon the city, and it is claimed by plaintiff that the city is an “adverse party” within the meaning of Section 550, L. O. L., which requires that the notice of appeal shall be served upon “such adverse party or parties as have appeared in the action or suit, or upon his or their attorney.” “An adverse party is a party whose interest in the judgment appealed from is in conflict with the modification or reversal sought by appellant”: Smith v. Burns, 71 Or. 133 (135 Pac. 200, 142 Pac. 352, Ann. Cas. 1916A, 666, L. R. A. 1915A, 1130). In Lane v. Wentworth, 69 Or. 242 (133 Pac. 348, 138 Pac. 468), Mr. Justice Burnett, observes:
“It has constantly been determined by this court that, although parties are both plaintiffs or both defendants, yet if an appeal would unfavorably affect *370the rights of one of them, as determined by the decree appealed from, he is an adverse party as respects his coplaintiff or codefendant, and that the jurisdiction of this court depends upon service of the notice upon all such parties: The Victorian, 24 Or. 121 (32 Pac. 1040, 41 Am. St. Rep. 838); Moody v. Miller, 24 Or. 179 (33 Pac. 402); Osborn v. Logus, 28 Or. 302 (37 Pac. 456, 38 Pac. 190, 42 Pac. 997); Stutter v. Baker County, 30 Or. 294 (47 Pac. 705); Conrad v. Pacific Packing Co., 34 Or. 341, 343 (49 Pac. 659, 52 Pac. 1134, 57 Pac. 1021); Cooper Mfg. Co. v. Delahunt, 36 Or. 403, 404 (51 Pac. 649, 60 Pac. 1); Hafer v. Medford etc. R. R. Co., 60 Or. 354, 356 (117 Pac. 1122, 119. Pac. 337).”
We can conceive of no way in which the interests of the City of Portland can be injuriously affected by this appeal. If the judgment of the Circuit Court should be reversed, that would not reinstate the City of Portland as a party defendant. If it should be affirmed, the plaintiff, would still be at liberty to begin another action — in fact, could have begun one at any time after the entry of judgment of nonsuit, and in case of a recovery have issued execution upon either judgment. Neither defendant could have called upon the other for contribution in any event as both were joint tort-feasors, if tort-feasors at all. So that in any view of the case we cannot say that as a matter of law the City of Portland would be injuriously affected by reason of any action we might take with reference to matters involved in the appeal.
2-6. We will now consider the case upon the merits. Among other provisions of the city charter we find the' following:
“The city council shall have power and authority to regulate, restrain, and prevent obstructions within the public streets, sidewalks, and places, and to make all needful regulations to keep and maintain the pub-*371lie streets, sidewalks, and places in a clean, open, and safe condition for public use,” etc.: Subdivision 61 of Section 73, Portland Charter.
By subdivision 12 of said section the council is given power and authority “to provide * * for the improving and repairing of streets,” etc. Other sections heretofore quoted in effect vest in the council all powers granted to the City of Portland by the charter. It is earnestly contended that the above provisions are purely legislative and impose no duty upon the council to repair the streets or any ministerial duties whatever. We do not so view the law. The power to control the streets of the City of Portland is one necessarily granted to it by its charter. The instrument by which it exercises that powbr is the city council. In Rankin v. Buckman, 9 Or. 253, this court, speaking through Lord, C. J., had occasion to construe certain sections of the charter of the City of Bast Portland which were practically identical with those here under discussion, and upon a complaint similar in terms to the one in the case at bar. That case disposes of many of the contentions made by defendants here. Mr. Chief Justice Lord, said:
“Having, then, the exclusive care and control of the streets and the means provided to repair them when defective, the duty which the law imposes upon the defendants is imperative to see that the streets are kept in a safe condition for the passage of persons and property, and if this plain duty is neglected and any one is injured, they are liable for the damage sustained.”
This language must be taken with the qualification that neither the city nor its officers are insurers of the safety of the streets and of the persons using them, but it may be said that there rests upon the council an absolute duty to exercise reasonable diligence to *372ascertain and keep itself informed as to the condition of its streets and to canse them to be repaired when defective. While snch duties may in some instances involve the passage of ordinances or resolutions, they partake more of a ministerial than a legislative character, and in case of matters provided for by ordinance the duty does not end with the passage of an ordinance requiring certain officers to examine into and report the condition of the streets. There must be some diligence on the part of the council to ascertain whether such officers are performing the duties assigned to them, and what is reasonable diligence under the circumstances must depend upon a variety of conditions. Nobody could expect the councilmen of thé City of Portland, with its twelve hundred miles of streets, to inform themselves personally as to the condition of the cross-walks in every part of the city, or, indeed, in any part of the city, unless such condition were so notoriously dangerous that it had become a matter of general public concern and discussion. The duty of a councilman in that respect, in the absence of any actual knowledge of a defect, is performed when he has used his best efforts to provide means to keep streets in repair and to have a sufficient force of employees to report defects as they occur, and other employees or subordinates to make the repairs. We do not propose to enter into any extended discussion of the law in such cases. The liability of each officer is a personal liability depending upon the diligence which he himself exercises as a guardian of the public weal to see that the streets are kept reasonably safe. It is in evidence here that the council had provided ample funds from which repairs might be made, that every policeman, and there are several hundred in the City of Portland, was in*373structed to report all defects in streets and walks, and that it had a city engineer and a corps of street inspectors whose duty it was to make such reports. There is no charge that the defendants were negligent in not providing funds or in failing to provide material, or guilty of negligence in the selection of employees or of lack of diligence in requiring reports as to the condition of the streets. None of these conditions are shown, but, on the contrary, it affirmatively appears that reasonable diligence has been exercised in all these respects. Counsel rest their whole case upon the circumstances that the defect had existed for so long a period and was so notorious the councilmen ought to have known of it. It is the universal rule that a public officer is not personally liable for the negligence of an inferior officer unless he, having the power of selection, has failed to use ordinary care in the selection: Story on Agency (9 ed.), § 321; Bowden v. Derby, 97 Me. 536 (55 Atl. 417, 94 Am. St. Rep. 516, 63 L. R. A. 223); Brown v. West, 75 N. H. 463 (76 Atl. 169); Moynihan v. Todd, 188 Mass. 301 (74 N. E. 367, 108 Am. St. Rep. 473); Bailey v. Mayor, 3 Hill (N. Y.), 531 (38 Am. Dec. 669); Walsh v. Trustees, etc., 96 N. Y. 427; Bowden v. Derby, 99 Me. 208 (58 Atl. 993).
7-10. It is conceived that Section 281 of the charter of the City of Portland, which attempts to exempt the ' city from liability for injuries arising from defective streets and to place that liability upon the officer by reason of whose negligence the injury occurred does not create any new or additional obligation as against such officer, as a city official who personally neglects to perform a specific duty was always liable irrespective of any statute prescribing such liability: Pullen v. Eugene, 77 Or. 320 (146 Pac. 822, 147 Pac. 768, 1191, 151 Pac. 474). It is contended *374by plaintiff’s counsel with much plausibility that this line of reasoning leaves plaintiff practically without a remedy, and were we to adopt the theory of defendant’s counsel such would be the result, but we cannot adopt that theory which in effect is that the city is not liable because of the exemption in the charter; that the commissioners are not liable because they have provided funds and used diligence in providing for inspection and had no notice of the defect; that the city engineer is not liable because he had under him inspectors charged with the duties of examination and inspection under orders to report any defect in the walk, and that these inspectors failed to report. This would leave the responsibility for the injury to rest finally upon the shoulders of some probably irresponsible watchman or inspector and would be practically a denial of a remedy. This under the peculiar provisions of the charter presents a view of the case not considered in any previous case brought before this court. Irrespective of the exemption clause in the charter the City of Portland would have been liable for the failure of Hailey, the street inspector, to report the defect upon the principle of respondeat superior. The city is out of the case as it stands here, neither party having appealed as to it, but it may well be doubted whether it is competent for the charter-making power to take away from plaintiff a complete remedy against the city, which is always solvent and responsible, and whittle down to the point where plaintiff will have a partial and doubtful remedy against the city officers or against a subordinaté officer whose position is, perhaps, a little lower than a deputy inspector and a little higher than that of the dog-catcher. To the writer it seems that such a conclusion is contrary to justice and in *375■direct opposition to the doctrine laid down in Batdorff v. Oregon City, 53 Or. 402 (100 Pac. 937, 18 Ann. Cas. 287).
This case was begun upon the theory that both the city and the mayor and commissioners who constitute the council were liable, the city for the failure of its officers and employees to use reasonable diligence to ascertain and remedy defects in the walks, and the commissioners and city engineer for like negligence on their part; but in our view while they might have been properly so joined the facts which would have justified a recovery against the city might not justify a recovery against the councilmen or the city engineer. The city under the doctrine of respondeat superior would be liable for the negligence of any officer authorized by it to see to the repair of the street or perhaps for a failure to designate such officer. The mayor and commissioners, on the other hand, as heretofore observed, are not liable if they have used reasonable diligence to provide funds for such repair and to see that a system of inspection and report of disrepair of walks is provided for and competent persons designated to make such inspections and repairs, unless the defect is so glaring and notorious and long-continued as of itself to create a presumption of knowledge of its existence, which is not the case here. "When the court, as the writer thinks, erroneously held that the city should be granted a nonsuit, it left counsel for the plaintiff in the embarrassing position of being compelled to contend that, to use their own language,
“the city commissioners and engineer, the city commissioners particularly, are the body in whom all this power rests and upon whom all these duties are imposed, and consequently they are liable to the same extent and in the same manner as the city itself would *376have been liable without the exempting provision in its charter.”
• Assuming the premise to be correct the reasoning of the counsel would seem to be logical. If the exempting provision is broad enough to make the members of the council and the city engineer liable for the neglect of subordinates in any event and irrespective of any diligence or lack thereof in their selection or supervision, then their counsel’s contention is correct and the ruling of the court upon the motion for non-suit was proper. But we apprehend that the negligence for which an officer of the city is responsible is his own personal negligence. In the very nature of things this must be so. An illustration will show the injustice of any other contention: Suppose, for instance, that the engineer had reported this defect to the council and, in the absence of funds, had requested that funds be voted for the purpose of making repairs, and that Albee and Brewster had voted to provide such funds and Bigelow, Dieck, and Daly had voted against the proposition, thereby defeating it, would it be contended for a moment that Albee and Brewster would be liable in damages for this injury which they had vainly attempted to prevent? Or suppose that two of the councilmen having obtained personal knowledge of the defect had failed to report it to their associates, would the negligence of these two be justly imputable to the other members of the body? The conclusion is irresistible that while before the attempted exemption of the city the negligence of its officers, either the council or subordinate officers, was imputable to it, such liability was not transferred to the shoulders of any city officer not actually or constructively negligent. The authorities cited by appellants amply sustain this view. The duty of making a *377personal inspection of the walks of the city or of personally repairing them is not imposed npon the mayor, commissioners, or the city engineer, bnt it is the duty of the commissioners to provide for such repairs and to make such regulations as are necessary to keep the streets in a safe condition. In other words, their responsibility ends with using reasonable diligence to provide funds, competent inspection, and report as to the condition of the streets and walks, and in the absence of actual personal knowledge or such public notoriety in respect to a defect as would indicate that they ought to have known of it by the exercise of reasonable diligence, they are not liable. There is no such notoriety shown here. Portland contains approximately a quarter of a million of inhabitants. It appears from the testimony that something less than a dozen people had noticed the defect, and that three or four of that number had casually mentioned it to neighbors, bnt nobody seemed to consider the matter serious enough to report to the authorities. The existence of the defect seems not to have been known to anybody except these few persons living in the immediate neighborhood and was not a matter of general public notoriety or concern. The plaintiff who resided within a block of the crossing testifies that she was entirely ignorant of the defect, and yet it is contended the mayor and commissioners with all the multitudinous duties devolving upon them should be adjudged to have been negligent and to pay the plaintiff $6,350 because they did not know of the existence of this defect and repair it. Under the circumstances here the existence of the defect in the walk for three weeks, or perhaps double that time, is no evidence of notice to the council or of lack of diligence on their part in the discharge of their duties. If one *378of the principal bridges in the town should become in such a state of disrepair as to be a public menace or impede the public travel, it naturally would become a source of public concern to many people, and the commissioners would in the ordinary course of affairs hear of it. If they were charged with the duty of making a personal inspection of the walks of the city and failed to find a- defect which was open and apparent, there might be some reason for the inference that a defect which had existed for several weeks should have been discovered and repaired, hut in the very nature of things they can act only through subordinate officers, and it is not claimed that any policeman or inspector ever made any report, and it is evident that no member of the council ever had any personal knowledge of the defect. There was no evidence to justify a finding* that the mayor and commissioners were guilty of negligence.
11. As to the city engineer it may be said that it was his duty to use reasonable diligence to ascertain the condition of the streets and walks of the city, and in case defects were found to exist to promptly inform the council or take such measures as are necessary to have the defects remedied. WhiTe these duties are personal to him to a limited extent, it follows from the very nature of the case that in a city the size of Portland the inspection cannot be performed by him personally, and it appears from the evidence that to a great extent such inspection must be made by persons not selected by him or under his control, but serving under civil service rules and appointed by another authority. In estimating, therefore, the diligence exercised by him personally it was proper to show the mileage of streets in the city and the efforts made by him personally to secure a proper and complete in*379spection and repair. In attempting to show this and in enumerating the duties imposed upon him Mr. Dater, the engineer, testified as follows:
“A supervision of all construction work in the nature of bridges, streets, and sewers, which work includes an average of a million dollars a year. The supervision of certain sewers and street repair work on funds voted by the council specifically for that work, and during the year 1915 there was upon street repair work three crews mainly employed on repair of macadam streets. I think at the particular time of this accident, or just prior to it, two of those crews were at work in the so-called Northeast district, which included the place of accident. One of those crews had been over this particular district shortly before the accident, and in connection with their duties of repairing the streets, and macadamizing the street, they did repair all cross-walks, gutters, and other parts of the street, which appeared to need attention. There are over 1200 miles of street in the city, and to give personal attention to it would require five and six years of walking to get over it.”
Plaintiff’s counsel moved to strike out such testimony as not being responsive to the question nor within the ruling of the court, and being a conclusion of the witness, which motion was allowed and the testimony stricken out. This was material error. The witness was entitled, in order to relieve himself of the charge of lack of due diligence in ascertaining defects in the street, to show, first, the nature of the task, and, second, the efforts he made to perform it. The law never requires impossibilities, and all it demands of any official is that he shall honestly and faithfully do his best under the particular circumstances. Having-done this he is blameless. The witness testified along the same line as follows:
“To show the efforts which were made to obtain information and keep track of such matters, I would *380say that all employees in the department were under written orders to report any defects in street surface, or any public property that they saw, or which is reported to them. I have to depend almost wholly upon these reports and on the reports from the police department. I presume reports from the police department are the most important, because that organization covers the entire city every day presumably. There is a record kept in the office of all complaints made by individuals, often complaints come in over the telephone. All complaints filed by the Police Bureau, those complaints are each given an individual number and they are reported at once to the officer or employee who should attend to them. There is every effort possible made to follow them up promptly. And dangerous cases — ”
This was also stricken out. He further stated:
“The orders are that all important cases, all dangerous cases* should receive immediate attention. In the matter of sidewalks, in this particular year, there were posted over twenty-seven miles of sidewalks for reconstruction. ’ ’
For the reason given above this testimony should have been allowed to go to the jury.
The judgment of the Circuit Court is reversed and a new trial awarded. Reversed and Remanded.
