delivered the opinion of the court.
Although the plaintiff contends that a street extends from Front Street for a distance of 160 feet, or 60 feet beyond the rear or north end of lot No. 1, yet, since there is no evidence to sustain a finding that a street extends farther than 100 feet or the length of lot 1, we shall confine our attention to the question of whether a street 40 feet wide extends from Front Street along the east side of lot No. 1. If Hadley did not by his acts and conduct dedicate the disputed strip as a street, then plaintiff cannot prevail, and therefore the first inquiry is whether there was a dedication.
The inquiry will not be influenced by the parol testimony given by Hadley to the effect that he intended to dedicate the land as a street. We do not undertake to determine whether that testimony was competent since it is in no wise necessary to a decision of this suit; and while there is a contrariety of judicial opinion concerning that character of evidence, we content ourselves by merely noting some of the relevant authorities and assuming that the evidence is incompetent: Hobson v. Montieth, 15 Or. 251, 256 (14 Pac. 740); Spencer v. Peterson, 41 Or. 257, 260 (68 Pac. 519, 1108); 1 Elliott on Roads and Streets (3 ed.), § 173; *147Los Angeles v. McCollum, 156 Cal. 148 (103 Pac. 914, 23 L. R. A. (N. S.) 378).
Dedications are of two general kinds: Statutory and common law: Nodine v. Union, 42 Or. 613, 616 (72 Pac. 582). Common-law dedications may either be express or implied: 1 Elliott on Eoads and Streets (3 ed.), § 133. Generally, by reason of the terms of the statute, a statutory dedication operates as a grant: 8 R. C. L., p. 897. Some authorities declare that common-law dedications always operate upon the principle of an estoppel, while others go no further than to say that such a dedication is of itself a distinctive common-law doctrine based upon principles analogous to those underlying estoppels. The theory usually accepted is: That to reclaim land would be a violation of good faith to the public and to those who have acquired private property with the expectation of enjoying the use contemplated by the dedication; and in case of the sale of a lot with reference to a plat there is the added feature that an easement indicated by the plat constitutes a part of the consideration passing to the purchaser: 8 R. C. L., p. 906; 13 Cyc. 437; 1 Elliott on Eoads and Streets (3 ed.), § 125.
Upon examination of the writing accompanying the plat it will be observed that there are no words of grant, and although Front Street is mentioned, no direct reference is made to any other street. Obviously it was the purpose of Hadley to comply with the requirements at that time exacted by the statute. The writing is not in the form usually adopted and it may well be the subject of debate as to whether it constitutes a perfect statutory dedication. We do not attempt to decide, however, whether the plat and writing as recorded produced a statutory dedication; but, for the purposes of this discussion we shall assume, with*148out deciding, that a statutory dedication was not effected. An unsuccessful attempt to dedicate land under a statute if followed by sales with reference to the plat may result in a completed common-law dedication: 8 R. C. L., 893, 897; 13 Cyc. 441; 1 Elliott on Roads and Streets (3 ed.), § 124.
The intent of the dedicator is the foundation and life of all dedications and the intent must be clearly manifested. Where the dedication is statutory in character the plat and writing generally furnish the means by which to ascertain the intent, and these, like” all other writings, must be construed by the terms contained in them. In the case of a common-law dedication, the intent is to be determined from what the dedicator said in making the dedication and by his acts and conduct; and the rule of construction is to give effect to the intent manifested: Christie v. Bandon, 82 Or. 481 (162 Pac. 248); Carter v. Portland, 4 Or. 339, 340, 343; Lewis v. Portland, 25 Or. 133, 134 (42 Am. St. Rep. 772, 35 Pac. 256, 22 L. R. A. 736); Kuck v. Wakefield, 58 Or. 549, 555 (115 Pac. 428); Jones v. Teller, 65 Or. 328, 332 (133 Pac 354); Parrott v. Stewart, 65 Or. 254, 259 (132 Pac. 523); Eugene v. Lowell, 72 Or. 237 (143 Pac. 903); Harris v. St. Helens, 72 Or. 377 (143 Pac. 941, Ann. Cas. 1916D, 1073); 8 R. C. L., pp. 890, 896; 4 Ency. of Ev. 110; 13 Cyc. 452; 1 Elliott on Roads and Streets (3 ed.), § 130.
We now turn to the plat and the writing accompanying it for the purpose of discovering whether Hadley intended to dedicate the 40-foot strip next to lot No. 1 as a street. At the time of filing the plat Hadley owned all the land including the disputed premises. No street existed on any part of the Hadley land until the plat was filed. There is no evidence to indicate that the 40-foot strip had ever been used *149as a right of way or a road, or as a street at any time prior to 1889, and therefore the words “street 40 ft. wide” did not describe a street previously existing, but, on the contrary, they refer to a street which in no way existed until delineated on the plat. The space made by the line drawn to the east of and parallel with the east line of lot No. 1, and the words “street 40 ft. wide” express in plain and unmistakable terms an intent to make a street of the 40-foot strip. The word “street” has a definite meaning. When the owner of land makes a plat and refers to a “street,” he does not mean a private way; but the word signifies a public way in all that the term implies: 1 Elliott on Roads and Streets (3 ed.), §21; City of Denver v. Clements, 3 Colo. 472; Smith v. City of Goldsboro, 121 N. C. 350 (28 S. E. 479). The plat and writing clearly manifest an intention on the part of Hadley to dedicate the disputed land as a street; and, indeed, the 40-foot strip appears upon the plat in such a manner as to be entirely inconsistent with any other theory: Oregon City v. Oregon & C. R. Co., 44 Or. 165 (74 Pac. 924).
It is true that the disputed premises were never improved as a street nor formally accepted by the county; but the well-recognized rule is that neither a formal acceptance by the county nor the immediate opening and improvement of a street are essential to complete an irrevocable dedication: Carter v. Portland, 4 Or. 339, 340, 347, 348; Meier v. Portland Cable Ry. Co., 16 Or. 500 (1 L. R. A. 856, 19 Pac. 610); Hogue v. Albina, 20 Or. 182, 186 (10 L. R. A. 673, 25 Pac. 386); Spencer v. Peterson, 41 Or. 257, 260 (68 Pac. 519, 1108); Oregon City v. Oregon & C. R. Co., 44 Or. 165, 178 (74 Pac. 924); Christian v. Eugene, 49 Or. 170, 173 (89 Pac. 419); Oliver v. Synhorst, 58 Or. *150582, 585 (109 Pac. 762, 115 Pac. 594); Moore v. Fowler, 58 Or. 292, 297 (114 Pac. 472); Silverton v. Brown, 63 Or. 418, 424 (128 Pac. 45); Harris v. St. Helens, 72 Or. 377, 387 (143 Pac. 941, Ann. Cas. 1916D, 1073); Barton v. Portland, 74 Or. 75; 79 (144 Pac. 1146); Nichols v. Title & Trust Co., 79 Or. 226, 244 (Ann. Cas. 1917A, 1149, 154 Pac. 391); Elliott on Roads and Streets (3 ed.), §§ 124 and 129.
The offer made by Hadley to dedicate the street became a completed and irrevocable dedication when he delivered the deed to Shaw. The conveyance was made with express reference to the recorded plat for lot number one is described as being lot No. 1 “as appears on the recorded plat of said Hadley’s Addition to Mill City in the recorder’s office at Salem in said Marion County”: Portland v. Whittle, 3 Or. 126, 129; Carter v. Portland, 4 Or. 339, 340, 346; Meier v. Portland Cable Ry. Co., 16 Or. 500 (1 L. R. A. 856, 19 Pac. 610); Steel v. Portland, 23 Or. 176, 184 (31 Pac. 479); Mutual Irr. Co. v. Baker City, 58 Or. 306, 321 (110 Pac. 392, 113 Pac. 9); Moore v. Fowler, 58 Or. 292, 297 (114 Pac. 472); Kuck v. Wakefield, 58 Or. 549, 552 (115 Pac. 428); Jones v. Teller, 65 Or. 328, 332 (133 Pac. 354); Spencer v. Peterson, 41 Or. 257, 260 (68 Pac. 519, 1108); Oregon City v. Oregon & C. R. Co., 44 Or. 165, 176 (74 Pac. 924); Christian v. Eugene, 49 Or. 170, 172 (89 Pac. 419); Hogue v. Albina, 20 Or. 182, 186 (10 L. R. A. 673, 25 Pac. 386); Nicholas v. Title & Trust Co., 79 Or. 226, 244 (Ann. Cas. 1917A, 1149, 154 Pac. 391); 8 R. C. L. 890.
Usually the dedicator employs language to the effect that he dedicates all his interests in the streets shown by the plat, and an examination of the Hadley plat and writing will disclose that neither this nor equivalent language is used; but, as said in Oliver v. *151Newberg, 50 Or. 92, 96 (91 Pac. 470): “Even where snch words of dedication are omitted, and the street is shown by the plat, the sale of lots by the proprietor with reference to snch plat is sufficient to complete such dedication.”
Ordinarily the sale of a single lot completes the dedication and more especially does the sale of a single lot effect a dedication of a street upon which the lot abuts; and consequently the sale of lot No. (1) to Shaw operated as an acceptance of the offer of Hadley to dedicate the adjacent land as a street and rendered the dedication irrevocable: Roberts v. Mathews, 137 Ala. 523 (34 South. 624, 97 Am. St. Rep. 56); 1 Elliott on Roads and Streets (3 ed.), § 128.
The deed delivered by Hadley to Wadsworth on April 29, 1904, expressly excepts “Hadley’s Addition to Mill City,” and therefore Wadsworth acquired no greater rights than Hadley owned; and Thompson, who purchased from Wadsworth, does not own more than his immediate grantor. The dedication which was effected by the sale of lot No. 1 to Shaw on April 18, 1889, not only bound Hadley but it also bound his successors in interest, Wadsworth and Thompson: Parrish v. Stephens, 1 Or. 73, 75 76; Portland v. Whittle, 3 Or. 126, 129.
The defense of adverse possession relied upon by the defendant must fail. It is true that Shaw inclosed the premises and used the land for a garden and this use was continued by his successors until about 1910. Hadley did not sell to Wadsworth until 1904. The testimony of Hadley demonstrates that the use made of the land by Shaw did not constitute adverse possession. If any person claimed the land adversely it was only after Wadsworth purchased in 1904. The uncontradicted evidence is that the fence *152was torn down and removed in 1910, and after that time the premises “lay as waste land” until July, 1914. The evidence fails to show adverse possession for ten years.
There is, however, an additional circumstance affecting the claim of adverse possession. In 1895 the legislature declared that all streets in unincorporated towns were public highways and jurisdiction over them was conferred upon the county courts of the various counties: Laws 1895, p. 57. At the same session of the legislative assembly an act was passed preventing the extinguishment of highways by adverse possession (Laws 1895, p. 57); the statute was re-enacted in 1903 (Laws 1903, p. 279); and is now codified as Sections 6371 and 6372, L. O. L.
Hadley dedicated a strip 100 feet long and 40 feet-wide as a street as shown on the plat and the dedication became irrevocable when the abutting lot was sold to Shaw, and since the completed dedication was not subsequently defeated, the plaintiff as the owner of lot No. 1 is entitled to use the- disputed strip as a street. The decree is reversed. Beversed.
