This is a petition to register title in fee simple, subject to rights of way, to a strip of land between Washington Street and Harrison Avenue in Boston, over which lies a private way known as Chickering Place.
The petitioners own the land and building at the southeasterly corner of Chickering Place and Washington Street. The respondents, the Ames Trustees, own the land and buildings on the north side of Chickering Place throughout its length. Other respondents own land abutting on Chickering Place.
The chief question is whether the petitioners own the fee of the entire Chickering Place.
Prior to 1822 title to the land included within the lines of Chickering Place, together with land on each side, had been acquired by Lemuel Hayward by two deeds, one from Nathaniel Sweetser and the other from Jacob Sweetser. He also owned land southerly of what is now Hayward Place, and that was included in the partition proceedings as was all his other real estate. After his death partition was made of his real estate by three commissioners appointed upon proceedings in the Supreme Judicial Court in 1822. The report of the commissioners was approved and accepted by the court. Accompanying that partition was a plan showing a subdivision of the Washington (then Newbury) Street property into lots with two passages running easterly from Washington Street and a third passageway at the east connecting the two; the lots having buildings thereon being left unnumbered and the vacant lots being numbered. The northerly passageway thirteen feet wide is. the present Chickering Place. The southerly passageway is the present Hayward Place and the connecting passageway at the east is within the present limits of Harrison Avenue.
*439In this partition, each of the lots set off to the several parties other than Joshua H. Hayward was described by metes and bounds together with the free and uninterrupted use and privilege in the abutting passageways. The portion of the estate set off to Joshua H. Hayward was described, not by metes and bounds, but, at the end of the commissioner’s report, as “Estate left undivided for Joshua H. Hayward Sweetser Estate in Newbury Street Reserving a right in the passage way 13 feet wide.” The estate thus set off in severalty to Joshua H. Hayward included the area north of Chickering Place to a depth recited as two hundred and eighty-nine feet from Newbury, now Washington, Street. The “Sweetser Estate in Newbury Street” as owned by Lemuel Hayward covered all the land now owned by the parties to this suit including the fee of the land in Chickering Place, but not that in Hayward Place or that in the other passageway now included in Harrison Avenue.
Each of the other lots abutting on said passageways was described as bounding “by” or “on” the respective passageways (Chickering Place, Hayward Place and the easterly way now in Harrison Avenue) with a clause as to free and uninterrupted privilege therein similar to that in the description of the parcel set off, for example, to Sarah H. Hayward, through whom the respondents claim a part of their estate. To her was set off a parcel on the easterly side of Newbury Street bounded southerly “by said passage way thirteen feet wide leading to Newbury Street there measuring one hundred and five feet and three inches, with a free and uninterrupted use and privilege in and to said passage way leading to said Newbury Street, which is to be kept open and used in common for the benefit of the owners of estates adjoining.” The respondents also claim a part of their estate through Joshua H. Hayward. The contention of the petitioners is that, by the rules for construction of deeds established previous to 1822 and then prevailing, the portion set off to Joshua H. Hayward included also the fee and soil of Chickering Place, and that no part of the fee and soil of Chickering Place passed to Joshua’s brothers and sisters under the description of the lots set off and assigned to them. *440The petitioners’ title to the land on which their building stands comes partly through Harriet Hayward, daughter of Lemuel, and partly from the trustees for his son, Joseph. The Ames Trustees’ title is through Joshua H. and Sarah H., son and daughter of Lemuel Hayward. There are four of these deeds from Joshua,— two dated September 11, 1823, the third dated October 11, 1823, and the fourth dated December 31,1835. All of these deeds describe the premises conveyed as bounding southerly “on” or “by” the thirteen-foot passageway (Chickering Place). By quitclaim deed dated February 3, 1836, Joshua conveyed to his brother, Joseph H. Hayward, through whom the petitioners claim their title, all his “right, title and interest in and to Sweetzer’s Court [now Chickering Place], so-called in Boston, being the fee of the soil in the passageway in said court and subject to the rights and privileges in the same granted to the owners of the building lots in said court.” In precisely similar language the same deed included a grant of Joshua’s interest in the fee of the soil of Hayward Place, and the unnamed passageway connecting the eastern ends of Chickering Place and Hayward Place. This deed is witnessed by Sarah H. Hayward and acknowledged before Charles Hayward, sister and brother respectively of the grantor and grantee. The evidence was undisputed, and it was conceded by each of the parties to this suit that their adversaries have whatever title passed to their respective predecessors in the partition of 1822. The petitioners introduced in evidence certain conveyances in the respondents’ chain of title which, they contended, were material and competent evidence, if as a matter of law the language of the partition deeds is not conclusive of the intent of the parties. One of these conveyances is a mortgage given in 1876, through foreclosure of which the Ames Trustees derive title to a lot near Harrison Avenue, which was set off in the partition to Sarah H. Hayward; the other is a deed to Robert and Freeman Wight of a portion of the width of their estate by their immediate predecessor in title dated February 28, 1903. The land conveyed by this deed is part of Lot 9, which was set off in the partition of 1822 to Charles Hayward. This mortgage and *441deed refer respectively to the northerly line and southerly line of Chickering Place as “boundaries of the granted premises.”
The judge of the Land Court filed a decision setting out at length the reasons leading him to the conclusion that the petitioners have not title to the fee and soil of Chickering Place beyond such portion as may be owned by them as a part of their lot on the corner of Chickering Place and Washington Street and, since their title to that tract was not before him, he ordered the petition dismissed. He granted certain requests for rulings in substance that the effect of the proceedings for partition was to vest in those, to whom the several parcels abutting on Chickering Place were set off, the fee and soil of that passageway to its center fine between the side lines of the several parcels extended. The petitioners excepted to the granting of these requests and to the ruling as to the state of their title in the fee of the passageway.
The case comes before us by exceptions. Hence only questions of law are presented, and the findings of fact made by the Land Court must stand if warranted on any view of the evidence with its justifiable inferences. Marvel v. Cobb, 204 Mass. 117. Boston Five Cents Savings Bank v. Massachusetts General Hospital, 255 Mass. 583, 586. Eaton v. Eaton, 233 Mass. 351, 369. G. L. c. 185, § 15. The general finding against the petitioners imports a finding of all subsidiary facts essential to that result, so far as permissible on the evidence. Adams v. Dick, 226 Mass. 46, 52. This case presents chiefly for interpretation the construction of a written instrument. If that were all, no deference could be paid to the decision of the trial judge and this court would decide its meaning. Creighton v. Elwell, 243 Mass. 580, 583. Gould v. Converse, 246 Mass. 185, 189. Farber v. Mutual Life Ins. Co. of New York, 250 Mass. 250, 253. The significance of words takes color from the time and circumstances in which they are used, and the intent of parties is almost always a matter of fact. Therefore'weight will be given to the findings made. Atlantic Maritime Co. v. Gloucester, 228 Mass. 519, 521, 522. Webber v. Cox, 256 Mass. 595, 597.
*442There is much to support the main contention of the respondents that upon the state of the law as it had been prior to 1822, manifested by authoritative judicial utterances, and as it was understood to be as late as 1838, a boundary “by” or “on” a public way in an instrument transferring title to real estate passed no title to the fee of the land under the way, but only to the line of the way. See Clap v. M’Neil, 4 Mass. 589, and Alden v. Murdock, 13 Mass. 256, decided before 1822, and Sibley v. Holden, 10 Pick. 249, Tyler v. Hammond, 11 Pick. 193, 213, and O’Linda v. Lothrop, 21 Pick. 292, decided between 1822 and 1838. See also Brown v. Peabody, 228 Mass. 52, 55. Under these adjudications rendered prior to Newhall v. Ireson, 8 Cush. 595, decided in 1851, a description like that in the case at bar might have been thought to transfer title only to the edge of the way. But it was said of this group of cases by Chief Justice Shaw in Phillips v. Bowers, 7 Gray, 21, 24, that they do not show that the point “whether by deed of land bounding on a highway, the grantor conveys all his title to the fee of the soil to the middle line of the way, or only to the side of the way, next to the land . . . was expressly raised and judicially decided on, though perhaps two of them imply that the judges giving the opinions” understood the law to be that title to the fee of the way would be excluded by such description. We do not attempt to review the cases there cited and to justify and amplify that decision. We accept it as conclusive. The subject was fully discussed with review of earlier cases by Gray, J., in Boston v. Richardson, 13 Allen, 146, 152, 153-155. It there was said: “In some opinions of this court it has indeed been implied or asserted that a boundary upon a road or street passed no title in the land under it. But in the more recent decisions the general rule has been repeatedly declared, and must now be regarded as the settled law of the Commonwealth, overruling whatever is irreconcilable in the earlier cases, that a deed bounding land generally by a highway, with no restrictive or controlling words, conveys the grantor’s title in the land to the middle of the highway. . . . The question whether any grant extends to the side line or the centre line of the high*443way is doubtless, according to the statement made by Chief Justice Shaw in Webber v. Eastern Railroad, 2 Met. 151, and approved by the court in Codman v. Evans, 1 Allen, 446, ‘a question of construction in each particular case, and depends, as in all other cases, upon the intent of the parties, as expressed in the descriptive parts of the deed, explained and illustrated by all the other parts of the conveyance, and by the localities and subject matter to which it applies.’ ” Again the matter was before the court in Crocker v. Cotting, 166 Mass. 183, where it was said by Holmes, J., at page 185, “The rule by which the mention of a way as a boundary in a conveyance of land is presumed to mean the middle of the way, if the way belongs to the grantor, is not an absolute rule of law irrespective of manifest intention, like the rule in Shelley’s case, but is merely a principle of interpretation adopted for the purpose of finding out the true meaning of the words used. Codman v. Evans, 1 Allen, 443, 446”; and at page 187, “As late as 1855, the application of the now accepted rule of law to boundaries upon private passageways was uncertain. Morgan v. Moore, 3 Gray, 319, 320. In 1857, the court were divided on the question. Fisher v. Smith, 9 Gray, 441.” In Gray v. Kelley, 194 Mass. 533, after quoting from Boston v. Richardson, 13 Allen, at pages 154, 155, as to the effect of deeds bounding the conveyed parcel on a way, at page 537 Chief Justice Knowlton said: “This shows the fundamental and principal reason of the rule. To this reason is added the probability that the grantor, if bounding on a street, under which the land presumably would be of little value to a private owner, would not be expected to care much to retain the title after parting with all of his property at the side of the street. But this rule has never been held to be anything more than a rule of construction, to be used in ascertaining the true meaning of the parties. For a time it was doubted whether it should apply to conveyances upon a private way; for the reason of it is less strong in its application to such conditions. On this question the court divided in Fisher v. Smith, 9 Gray, 441. See Crocker v. Cotting, 166 Mass. 183, 187. But it is now well established that, in case of a conveyance giving an *444ordinary private way as a boundary, if the title of the grantor extends to the. centre of the way, he will be presumed to have intended to pass title to the centre of the boundary, unless there is something in the deed to show a contrary intention. ... It is always a question what is the intention of the parties, and ordinarily the intention to retain the title in private land, over which a right of way is granted, is more easily indicated than the intention to limit one’s grant by the side line of a public street when the grantor owns to the centre of it. Nothing is ever conveyed except what is included within the boundaries of the lot described, and the language of the deed must be scrutinized, in its application to the locus, to see where the true boundaries are.” This principle was reaffirmed in Frost v. Jacobs, 204 Mass. 1, 4. It must be taken to be the settled law of the Commonwealth. Perplexing questions arise in the application of the principle to varying facts. Lemay v. Furtado, 182 Mass. 280, 282. McKenzie v. Gleason, 184 Mass. 452, 457. Gould v. Wagner, 196 Mass. 270, 275. Kaatz v. Curtis, 215 Mass. 311, 314. Lynnfield v. Peabody, 219 Mass. 322, 336, 337. Brown v. Peabody, 228 Mass. 52, 55. McCarthy v. Everett, 234 Mass. 231, 233.
The result of these decisions is that, while there have been some fluctuations in the form and emphasis of expression during the six score years which' have elapsed since the words of Chief Justice Parsons in Clap v. M’Neil, 4 Mass. 589, the underlying principle on which they all rest is that the intent of the parties in each instance was ascertained from the words used in the written instrument interpreted in the light of all the attendant facts. That is the general principle governing the interpretation of deeds, Simonds v. Simonds, 199 Mass. 552, 554, and of other instruments creating rights in property, Eustace v. Dickey, 240 Mass. 55, saving only that the intent thus found be not repugnant to some positive rule of law or the terms of the instrument. Expressions in some of the earlier cases, which bear a contrary aspect, are to be taken as not essential to the point decided and hence not binding upon the court or falling within the protection of the doctrine of stare decisis. See Swan v. Justices of the Superior Court, 222 *445Mass. 542, 545; Kennedy v. Commissioner of Corporations & Taxation, 256 Mass. 426, 431. Those expressions may well have been the justifiable basis of a more or less widespread opinion in 1822 as to the state of the law respecting a case like the present. That view as to the state of the law must be. given weight as an important though not decisive factor in ascertaining the intent of the parties to a particular instrument. It has been said that such state of the law must be “cautiously used.” Hamlen v. Keith, 171 Mass. 77, 79. But it may permit a just result not otherwise possible. Brown v. Peabody, 228 Mass. 52.
There are indications in the record that the trial judge thought the law to have been settled in 1822, to the effect that such descriptions as set off the several parcels abutting on Chickering Place to different owners, in the report of the commissioners, transferred the fee in the private way now known as Chickering Place throughout its entire width and length to Joshua H. Hayward. As already pointed out, that is not so. If that had been the settled law at that time, there would be difficulty in supporting the conclusion of the trial judge. Parties have a right to contract, and commonly do contract, in view of settled rules of property established by authoritative decisions of courts of the jurisdiction. Having entered into an engagement as to real property in the light of such declared rules, there would be grave doubt about holding them at a later time to some other standard. It is a principle of wide application that what “a court declares to be the law always was the law, notwithstanding earlier decisions to the contrary.” Ross v. Freeholders of Hudson, 90 N. J. Law, 522, 527. Center School Township v. State, 150 Ind. 168, 173. Falconer v. Simmons, 51 W. Va. 172, 173-176. 1 Blackstone’s Com. 70. Yet, notwithstanding that principle and not at all incompatible with it, is another often asserted; “The sound and true rule is, that if the contract when made was valid by the laws of the State, as then expounded by all the departments of its government, and administered in its courts of justice, its validity and obligation cannot be impaired by any subsequent act of the legislature of the state, or decision of its courts, altering the construction of *446the law.” Ohio Life Ins. & Trust Co. v. Debolt, 16 How. 416, 432. Gelpcke v. Dubuque, 1 Wall. 175, 206. (See Tidal Oil Co. v. Flanagan, 263 U. S. 444, 452.) Havemeyer v. Iowa County, 3 Wall. 294, 303. Olcott v. Supervisors, 16 Wall. 678, 690. County of Ralls v. Douglass, 105 U. S. 728, 732. Anderson v. Santa Anna, 116 U. S. 356, 361, 362. Taylor v. Ypsilanti, 105 U. S. 60, 71. In such instances, as applied to contracts affecting vested property interests, the clearing away of errors, which have crept into decisions by overruling what has hitherto been said, is not infrequently treated as prospective in operation. Douglass v. County of Pike, 101 U. S. 677, 687. Bank of Philadelphia v. Posey, 130 Miss. 825. Falconer v. Simmons, 51 W. Va. 172, 177, 178. See for collection and review of cases, 18 Colum. L. Rev. 230-251. We do not now undertake to delimit with accuracy these principles and their scope and application, but reference is made to them to show that, whatever their precise sweep, they have not been overlooked but are regarded as not relevant to the case at bar in view of the state of our law in 1822 and in the intervening years, as already elaborated.
The findings of fact are summarized in a brief paragraph by the trial judge: “ The laying out of the three passageways, the careful provisions as to their use in common as appurtenant to all of the lots abutting on them, the fact that this was a partition in which all of the land was to be divided, the absence of any language that would, on the construction contended for by the petitioners, dispose of the fee in the other two passageways, all seem to me to show a clear intent, consistent with the presumption which must govern unless otherwise rebutted, to apportion the fee in the passageways to the respective lots abutting thereon. The land set off to Joshua was simply the remaining land of the Sweetser Estate, which did not cover the other passageways, not included in the previous assignments to the other parties to the partition, and was fairly designated as ' Sweetser Estate’.”
It cannot quite be said, in our opinion, that all the circumstances disclosed fail to warrant these findings and the final inference drawn. The case at bar is fairly within the authority of Clark v. Parker, 106 Mass. 554, also a case aris*447ing out of a return of commissioners to make partition, where the order for partition was made in 1842.
It is not necessary to discuss other questions argued. They become immaterial in view of our conclusion on the main point.
Exceptions overruled.
