i Conveyances-covenant: measure of damages. Tbe appeal involves tbe right to recover tbe damages due to falsely representing tbe existence of a public alley through which the purchaser of a part of a lot might reacT the .street in front, and a breach of warranty in the deed conveying tbe same, The deed to Mrs. Talbert specifically described the right of way bach of tbe tract sold to her and “ to an alley running east and west on the north side of out lot six.” This amounted to a distinct assertion of the existence of such an alley. Tbe sole object had in providing a north and south right of way extending to this alleged alley was to enable the grantee to obtain access to Harrison street from tbe rear end of her lot. This supposed alley bad been traveled somewhat by defendant for several years, and was used by the grantee, and her heirs up to the time it was closed in 1902 by one Hastie, who had purchased all of lot 5 and the part of lot 6 remaining, specifically described so as to include the right of way for alley purposes conveyed to Mrs. Talbert, as well as the alleged east and west alley, from one Teas, to whom defendant bad deeded it by like description. Each of these deeds, however, contained a clause saying it was “ made subject to right of way over the above tracts in a deed to Elora E. Talbert.” This clause, while general, clearly directs the grantee’s attention to tbe recitals contained in the deed to plaintiffs’ decedent. Erom these it appeared, not only that a right of way for alley purposes a rod wide from tbe railroad to tbe alley along the north side of tbe lot bad been conveyed to her, but also the existence of such an alley was asserted. But no alley had *376been platted, and there is no claim that it had been established by prescription. If it existed, it was by virtue of an implied covenant of its existence. Certainly there was no alley, private or public, prior to the execution of the deed. The entire tract belonged to defendant, and the place traveled was merely made use of to gain access to his premises and after the conveyance by plaintiff and their decedent. But the deed described it as an alley, and conveyed a way to it for alley purposes.
In passing on the admissibility of evidence and in giving and refusing instructions, the court ruled the measure of damages to be the difference between the market value of the parcel of land conveyed as it was without a way along the north line of .lot 6 and such value of the lot as it would have been had there been a public alley as represented. Appellant contends that this was error, in that, though there was no public alley, a private way passed as appurtenant to the land by implied covenant of the grantor that an alley was there. This is on the theory that the grantor, having described the alley as forming a part of the boundary, or as an extension of the way forming the boundary, is estopped from asserting that there was no such passageway. The doctrine was recognized in Garstang v. City of Davenport, 20 Iowa, 359, where one of the boundaries was a “ twenty-foot alley to be laid out,” and the right to such alley was sustained on the theory expressed in Tufts v. City of Charlestown, 2 Gray (Mass.)271: “When a grantor conveyed land, bounding it on a way or street, he and his heirs are estopped to deny that there is such a street or way. This is not descriptive merely, but an implied covenant of the existence of the way.” This statement of the rule is fully confirmed by authority. See Jones on Easements, section 227, where authorities are collected, and Dill v. School Board, 47 N. J. Eq. 421 (20 Atl. 739, 10 L. R. A. 276), where the earlier cases are noticed, among them Roberts v. Karr, 1 Taunt, 495, in *377which Chief Justice Mansfield tersely stated the principle on which the decisions proceed thus: “ If you (lessor) have told me in your lease that this piece of land abuts on a road, you cannot be allowed to- say that the land on which it abuts is not a road.” The necessity that the grantor own the fee in the land represented as a street or way is apparent. Howe v. Alger, 4 Allen (Mass.), 206. Also that the street or way be designated as a boundary is equally essential. If merely referred to as part of the description as a starting point or the termination of a line, or if the street or way is coincident merely with the line described, this will not suffice because not amounting to the assertion of the existence of the street or way as a boundary. Lankin v. Terwilliger, 22 Or. 102 (29 Pac. 268); Brizzalaro v. Senour, 82 Ky. 358. On the other hand, if designated as a boundary, this does not limit the street or way to that abutting the land conveyed. Thus in McConnell v. Rathbun, 46 Mich. 303 (9 N. W. 426), included in the conveyance was “ the right of way of an alley ten feet wide on rear end of said eighty-two feet.” The grantor had owned the land between this description and the street, and the court held that “ this vi termini implies a passageway leading away from the land conveyed ” to such street. In other cases, where lots are sold by a plat as on a street, the grantee is held to have an easement in such other street also as will afford him reasonably convenient access to his property. See Regan v. Boston Gas L. Co., 137 Mass. 37; Schermerhorn v. Todd, 51 Mich. 21 (16 N. W. 304), and Fox v. Union Sugar Refinery, 109 Mass. 292, where the land was conveyed by a description which bounded it in a private way not defined in the deed, but shown upon a plan referred to therein, and the court held that the deed operated as an estoppel upon the grantor, and precluded his denying the existence, not only of the abutting way, but of any of the connecting ways represented on the plan which would enable the grantee to reach the public roads in any direction. *378In Langmaid v. Higgins, 129 Mass. 353, 356, tbe principle is lucidly stated by Colt, J.: “A deed in which the premises conveyed are bound on a defined and existing passageway gives to the grantee by estoppel rights, not only in that part which adjoins his own land, but also by necessary implication in such portion of the whole way as will make the same available and useful as an appurtenance to the estate granted. The extent of the grantee’s right beyond the limits of his land will depend upon the nature and character of the way and its connection with the public streets as affording a convenient outlet from his land. When the extent or limits of the way are defined in the deed by reference to a plan or otherwise, the estoppel is not confined to so much of the way as is necessary for the enjoyment of the granted premises, but extends to the whole way-as defined.” It is apparent that much of necessity depends on the intention of the parties to the instrument in determining whether an easement passes by implied 'covenant, and this is to be gathered from the nature of the transaction in so far as revealed, the situation of the parties, and the state of the thing granted. In re Opening Brook Ave., 58 N. Y. Supp. 163 (40 App. Div. 519); Huttenmeier v. Albro, 18 N. Y. 48; Winston v. Johnson, 42 Minn. 398 (45 N. W. 958).
It can make no difference whether the seller exhibit a way on a plan or assert one in his conveyance. If he conveys land bounded by a street or way used as appurtenant to the premises conveyed in connection with another street or way necessary as an outlet in such a manner as to unequivocally assert the existence of the latter, he cannot be heard to deny its existence thereafter, and because of this a covenant that it exists is implied which runs with the land. In the case at bar the way described as extending from the railroad to the east and west alley was appurtenant to the land conveyed, and the only conceivable object in including it in the deed was to afford the grantee an outlet *379from the back end of his premises to Harrison street. This is manifest from an examination, of a map of the lots:
The way was for alley purposes and extended from along the premises conveyed to the alley on the north side of lot 6 with the manifest object pf enabling the grantee to pass along this way to the “ alley,” and then down to the street. The defendant then owned the land at the place where he asserted the east and west alley existed, and in harmony with the decisions cited could not be heard to say that no alley, in fact, existed there. From these circum*380stances a covenant is implied under wbicb a private way passed to tbe grantee, and the court erred in not defining the measure of damages as the difference between the market value of the property with this private way annexed and appurtenant thereto, and such value of the property as it would have been with a public alley along the north side of lot 6..
2. Same: term strueci ” bon“ II. Error is also assigned in an instruction to the jury that “ if the defendant told plaintiff, J. H. Talbert, that there was an 1 alley ’ running east and west on the north side of out lot 6', and made' no explanation as to whether such alley was a pub-lie alley or a mere private way, then and in that ease the term ‘ alley ’ under the circumstances of this case would imply that it was a public alley; that is, a permanent right of way, open to the use of the public generally.” The statutes relating to platting a town site or additions thereto authorize the dedication of alleys. Section 916 of the Code expressly requires that subdivisions “ shall be divided by streets into blocks with alleys separating abutting lots and such blocks, streets and alleys shall conform as nearly as practicable to the size of blocks and the width of streets' and alleys in such city or town and such streets and alleys shall be extensions of the existing system of streets and alleys thereof.” Such alleys, upon the acceptance of the dedication tendered by filing the plat, are under the authority of the cities and towns, whose councils may “ widen, straighten, narrow, vacate, extend, improve and repair them.” Section 151, Code. Of course, alleys may be private and these are ordinarily such as have not been dedicated to the public use, and to which the general public is denied access or which are set apart for some particular purpose. A private passage or way is sometimes referred to as a private alley, especially when bordered by trees or otherwise defined or inclosed. But alleys in cities and towns usually are public, and the private alley therein *381is exceptional. Density of population render them necessary for easy access to abutting properties, and, though sometimes confused with streets in attempts to define them, they are readily distinguishable. ■ An alley may be so extensively used for public travel as to justify designating it a “ narrow street in common use,” as was done in Bailey v. Culver, 12 Mo. App. 183, or referring to it as a road, as Sharett’s Road, 8 Pa. St. 92. See, also, Kalteyer v. Sullivan, 18 Tex. Civ. App. 488 (46 S. W. 288). Their principle purpose is to furnish the owners of abutting lots and those dealing with such owners convenient access thereto. Dodge v. Hart, 113 Iowa, 685. See, also, Milliken v. Denny, 135 N. C. 19 (47 S. E. 132) ; City of Chicago v. Borden, 190 Ill. 430 (60 N. E. 915). Alleys are not a substitute for streets, but serve as means of accommodation to a limited neighborhood for chiefly local convenience. Beecher v. People, 38 Mich. 291 (31 Am. Rep. 316). When one is dealing with lots in platted ground, and refers to an alley or alleys therein, the presumption is that he has reference to an alley or alleys included in the plat. Such ways are ordinarily public in cities and towns, and, when a deed conveying platted grounds refers to an alley, the fair inference is that an alley platted for public purposes is intended. The same is true in speaking of such an alley, for, if not qualified by the term “ private,” the alley is conventionally understood, in its relation to plats in cities and towns, to mean the harrow way in common use for the convenience of owners of lots abutting thereon, and those dealing with them. Bailey v. Culver, 12 Mo. App. 183. See 2 Am. & Eng. Ency. of law (2d Ed.), 149. The instruction was correct.
TTT- The fifth instruction was rightly refused. Jamison v. Jamison, 113 Iowa, 720. The question as to whether decedent was charged with notice of the plat was disposed of in White v. Smith, 54 Iowa, 233. Whether the. *382cause of action based on deceit alleged might be maintained by plaintiffs was not raised in argument.
Because of the erroneous ruling with reference to the measure of damages, the judgment is reversed.
