delivered the opinion of the court:
Nellie Carlin, as administratrix of the estate of Julius Mell, deceased, brought an action against the city of Chicago and Thomas F. Pickham to recover damages for the benefit of the next of kin of the deceased for the negligent killing of said Julius Mell. The declaration contained three counts, in each of which it is charged that the death of Julius Mell, a child six years of age, was caused by the negligence of the defendants in failing to guard or protect a large piece of boiler or header-pipe which was negligently placed and permitted to remain on Fourteenth street near the plant or factory of the defendant Pickham, which was known as the Thomas F. Pickham Boiler Works, situated on said Fourteenth street, in the city of Chicago. After the Statute of Limitations had run plaintiff obtained leave to amend her declaration, and amended the same by striking out the word “street” where the same appeared in the several counts and inserting in lieu thereof “place.” The *566amendment to the declaration consisted in the change of this single word. After this amendment was made the city of Chicago filed a plea setting up the Statute of Limitations, alleging that the cause of action stated in the amended declaration was another and a different cause of action from that stated in the declaration as originally drawn. Plaintiff below demurred to this plea and her demurrer was overruled. She elected to abide by her demurrer and judgment was rendered against her. The cause was discontinued as to Pickham. Plaintiff below appealed to the Appellate Court, and that court affirmed the judgment below but granted a certificate of importance and an appeal to this court. If the declaration, as amended, stated a different cause of action from the one stated in the original declaration the judgment of the Appellate Court should be affirmed, otherwise it should be reversed.
“Fourteenth street” and “Fourteenth place” do not necessarily refer to different localities. Webster defines a street to be “a city road.” The word “street”. is a generic term, and includes all urban ways which can be, and are generally, used for ordinary purposes of travel. It is a highway free to all, and maintained not for private gain but public benefit. (Elliott on Roads and Streets, 12; see 7 Words and Phrases, title “Street.”) The word “street” may include a bridge which is a part of it; (Langlois v. City of Cohoes, 58 Hun, 226; Floyd, County v. Rome Street Railroad Co. 77 Ga. 614;) and a mere cul de sac,—that is, a street open at one end, only,—is included in the general term “street;” (Bartlett v. City of Bangor, 67 Me. 460;) and it was .held by this court to be a term broad enough to include a boulevard. (West Chicago Park Comrs. v. Father, 171 Ill. 146.) While the word “street” would not include a mere private way, it does include all the public roads or ways within the municipality over which it has jurisdiction and as to which it owes the public the duty of *567exercising reasonable care to keep and maintain them in a reasonably safe condition for public use. The word “place” has several meanings. In its primary and most general sense it means locality, situation or site, and it is also often used to designate an occupied situation or building or an estate. The third definition given by the Standard Dictionary is: “An open space or square in a city; also, a court or street; especially a short or subordinate street, as a market place, Astor place, etc.” It is in this last sense' the word “place” is used in the amended declaration. The word “place” means simply a particular kind of street, but it is included within the generic term “street.” The expressions “Fourteenth street” and “Fourteenth place” are manifestly both intended to describe the same locus in quo. This conclusion is rendered more certain by the averment contained in both the original and amended declarations, that the “city of Chicago had control of certain streets, and among others was in charge of Fourteenth street, (or place,) particularly at or near the plant or factory of Thomas F. Pick-ham on said Fourteenth street.”
Taking the entire description of the location of this injury into account, it would be a strained and unnatural construction of the language used to hold that the original dec•laration charged that this child was killed at one place and the amended declaration at another and different place. While the amendment in question was no doubt made merely to avoid the possible objection of a variance, it was not necessary, since if the proof had shown that the accident happened on a particular public street of the city described as Fourteenth street, proof that the locus in quo was known and usually described as Fourteenth place would not have constituted a substantial variance, since the more specific term “place” is included in the generic term “street.” Even an indictment describing a thing by its generic term is supported by proof of a species which is clearly comprehended *568within such description, (1 Greenleaf on Evidence, sec. 65.) In certain local actions, such as trespass quare clausum fregit, the locus in quo is legally essential to and of the substance of the action, and a specific legal .description thereof, when given by the pleader, being material to the right of recovery, should be substantially proved as laid and a variance therefrom will be fatal; (22 Ency. of Pl. & Pr. 587; North Birmingham Street Railway Co. v. Calderwood, 89 Ala. 247; Wertz v. State, 42, Ind. 161;) and in all proceedings in rem, such as condemnation, and tax proceedings, the property involved must be accurately described and.the proof must correspond with the allegation. Dickerson v. Burke, 25 Ga. 225; 1 Elliott on Evidence, sec. 197, and cases there cited.
The case of Wisconsin Central Railroad Co. v. Wieczorek, 151 Ill. 579, illustrates the doctrine now under consideration. That was an action for an injury to real estate from the construction and operation of a steam railroad in a street in front of and adjacent to the plaintiff’s premises, and part of the injury charged was the obstruction of the street with trains. The evidence showed that the railroad was not upon the street or any part of it, and this court held that in an action such as that, the description of the locus in quo is legally essential to and of the substance of the action and must be proved as laid in the declaration. Derrigon v. Rutland, 58 Vt. 128, was an action for dam-, ages to land from the construction of a sewer, and it was held that the description of the sewer was material and that a variance in the proof from* the description in the declaration was fatal. But an action for personal injury or for negligently causing the death of another is not a local action and a description of the particular locality where the' tort was committed is not an essential element of the cause of action. A declaration against a municipality which alleged all of the elements of a cause of action, and charged, *569in general language, that the injury happened upon one of the public streets of the municipality, without other more specific description, would state the substance of a good cause of action, and we have no doubt such a declaration would be good after verdict. The particular place where an injury occurs is not an element of the cause of action.
In Chicago City Railway Co. v. McMeen, 206 Ill. 108, the original declaration alleged that the injury occurred while the plaintiff was a passenger on one of the street cars of the defendant on State and Lake streets, in the city of Chicago, at a point between Thirty-eighth and Thirty-ninth streets. After the Statute of Limitations had run the plaintiff amended the declaration by striking out “State and Lake streets” and inserting “Cottage Grove avenue,” so that the declaration alleged that the injury occurred between Thirty-eighth and Thirty-ninth streets, on Cottage Grove avenue. The Statute of Limitations was pleaded and issue joined thereon. The judgment being for the plaintiff, an appeal was prosecuted to the Appellate Court, where the judgment below was affirmed, and the cause, by a further appeal, was brought to this court. It was strenuously insisted in this court that the amendment to the declaration, which made an entire change as to the location of the injury, stated a new cause of action. The question presented received the mature and painstaking consideration of this court. In discussing this question the court, speaking by Mr. Justice Ricks, on page 115 said: “Counsel for appellant cite numerous cases and text authorities on the proposition that even in transitory actions the allegation of place, if matter of description, is material and must be proved as laid. This is undoubtedly a correct statement of the law as laid down in Wabash Western Railway Co. v. Friedman, 146 Ill. 583, and Lake Shore and Michigan Southern Railway Co. v. Ward, 135 id. 511, and would be applicable to the case at bar if we were called upon to determine whether *570there was a variance between the facts as proved on the trial and the allegations of the original declaration. The cpiestion before us is whether a new cause of action was introduced by an amendment which alleged a different place as the occurrence of the injury from that alleged in the original declaration. It might well be true that the facts proved under that amendment were at variance with the allegations of the original declaration, and still it would hot necessarily follow that- the allegations of the amendment introduced an entirely new and distinct cause of action. This is evident from the nature of a variance. Take the case of several counts in a declaration. The very object of stating the same cause of action in different counts is to prevent a variance. Because the proof corresponds, let us say, to the third count and is at variance with the first and second, it does not follow that the first and second counts set up a new and distinct cause of action from that contained in the third. We think this will demonstrate clearly that there is a broad distinction between the cases of variance and cases where a new cause of action is introduced. In Swift & Co. v. Foster, 163 Ill. 50, this court said (p. 52) : ‘The negligence of the defendant, whereby the death of Mullen was caused, might well be stated in different ways in the several counts, in order to prevent a variance between the allegation and proofs without setting up different and distinct causes of action.’ The distinction may be illustrated in another way. A plaintiff must allege and prove every element that constitutes his cause of action; and the converse is true, that elements constituting a cause of action are those that must be alleged and proved. In the case at bar the venue was laid with certainty, and it was not necessary to allege with particularity the descriptive matters of place, but having been laid it was necessary, in order to prevent a variance, that they be proved as laid. An unnecessary allegation never *571becomes an element of a cause of action, and yet an unnecessary allegation must frequently be proved as laid to prevent a variance. The allegation, with particularity, of the street upon which the injury occurred was altogether unnecessary. The declaration laid the venue in ‘Cook county, Illinois,’ and it would have been a legally sufficient statement to have alleged that the injury occurred in the ‘county aforesaid.’—Read v. Walker, 52 Ill. 333; St. Louis, Jacksonville and Chicago Railroad Co. v. Thomas, 47 id. 116.”
The language of this court which we have quoted above at length would seem to be a conclusive and authoritative answer to the contentions of appellee in the case at bar. Applying the test suggested in the McMeen case to the case at bar, let it be supposed that appellant had hied a declaration of two counts, in one of which it was alleged that appellant’s intestate was killed, through the negligence of appellee, on Fourteenth street near the plant or factory known as the Thomas F. Pickham Boiler Works, in the city of Chicago, and in the second count the death was alleged to have occurred in the same manner at Fourteenth place near the plant or factory known as the Thomas F. Pickham Boiler Works, in the city of Chicago. Such a pleading Would be clearly within the rule allowing one to state his cause of action in different words in order to meet possible variances in the proof. While it is not an essential element of a cause of action for a personal injury to state with particularity the exact place where the injury was inflicted, still the rule is well established that where the pleader alleges the location he will ordinarily be held to prove the allegations made, and evidence of an injury at another time or place would be open to the objection of a variance. But the doctrine of variance is one thing and the statement of another and different cause of action is something else. There are certain propositions of law which must be regarded as fully established by the decisions of this court, to-wit:
*572 (a) ,If the original declaration fails to state any cause of action whatever, and an amended declaration is filed, after the Statute of Limitations has run, which does state a cause of action, the filing of such an amended declaration will be regarded as the beginning of the suit for that cause of action and the statute will constitute a good defense. Foster v. St. Luke’s Hospital, 191 Ill. 94; Doyle v. City of Sycamore, 193 id. 501; Mackey v. Northern Milling Co. 210 id. 115.
(b) If an amendment introduces a new cause of action not stated in the original declaration, the running of the Statute of Limitations is not arrested as to such new cause by the filing of the' original declaration, and the statute may be pleaded to the cause of action stated in the amended declaration. Fish v. Farwell, 160 Ill. 236; Chicago City Railway Co. v. McMeen, supra.
(c) If the amended declaration re-states the original cause of action in a different form, the filing of such an amendment relates back to the commencement of the suit and the Statute of Limitations is not a defense. North Chicago Rolling Mill Co. v. Monka, 107 Ill. 340; Swift & Co. v. Foster, supra; Swift & Co. v. Madden, 165 Ill. 41; Chicago and Eastern Illinois Railroad Co. v. Wallace, 202 id. 129; Chicago City Railway Co. v. McMeen, supra; Wabash Railroad Co. v. Bhymer, 214 Ill. 579; Heffron v. Rochester German Ins. Co. 220 id. 514.
One test by which it is determined whether the different counts are for the same or different causes of action is whether the same evidence would support a judgment rendered upon either. This does not mean that the evidence must be admissible, indifferently, under both counts if it was objected to on the ground of a variance. The question under this test is, would the same evidence, unobjected to, sustain the substantial averments of both counts? Another test is, could a judgment under one count be sue*573cessfully pleaded as a former adjudication against the cause of action set out in the other count ? In the case at bar the cause of action stated in the original and amended declarations is the same under either test, and the demurrer to the plea of the Statute of Limitations should have been sustained.
The degree of care which a city is required to exercise to keep its streets and sidewalks in a reasonably safe condition will vary according to the location, character and extent of the use to which they are put. The city cannot be expected to use the same degree of care over streets and walks in outlying districts that are but little used as is required in respect to those in the busy centers, which are constantly used by large numbers of persons. The duty is of the same general character but differs in degree and must be commensurate with the danger to be apprehended from its neglect. The extent of the duty in any given case, and whether it has been performed, is a question of fact for the determination of the jury. It cannot, therefore, be said that the duty of a city in respect to its streets and sidewalks is the same in one locality as in another, hence a declaration which charges a municipality with a violation of its duty to the public in failing to use reasonable care in respect to a street or a sidewalk in a particular designated place might not be the same duty, in degree, that would be required of the municipality in another locality,—and this was the basis of this court’s decision in Gillmore v. City of Chicago, 224 Ill. 490. In that case the injury was alleged to have occurred at a particular point on a certain street. After the Statute of Limitations had run the declaration was amended, by which the place of injury was located upon another street. In that case there were two different localities described and not two descriptions of the same locality, and this appeared from the declaration. In the case at bar it is clear that the description *574given in the original declaration and that introduced by the amendment refer to one and the same place. The Gill-more case is distinguishable from the case at bar in this respect. There is no conflict between the McMeen case and the Gillmore case. In the McMeen case it was the duty of the carrier to a passenger that was alleged to have been violated. That duty differs from the duty of a municipality in respect to its streets and sidewalks. The duty of the carrier to its passengers does not vary but is as high a duty in one place as in another. The McMeen case is cited in the Gillmore case and is there distinguished. The McMeen and Gillmore cases are not in conflict with each other, and neither of them is in conflict with the views that we have herein expressed.
The judgments of the superior court of Cook county and of the Appellate Court for the First District are reversed and the cause remanded to the superior court, with directions to sustain the demurrer to the plea of the Statute of Limitations, and for further proceedings not inconsistent with the views herein expressed.
Reversed and remanded, with directions.
