Bell, J.
We take it to be clear that at common law, as between the grantor and grantee, and those claiming under them, every deed conveys the property described in its existing state; that is, as it usually and rightfully is at the time of the execution of the conveyance. Such deed is to be construed in all its parts with reference to the actual, rightful state of the property conveyed at the time of the conveyance, unless some other time is expressly referred to. This position does not require the citation of any authority. No man supposes that when he buys land he has any claim growing out of the fact that the timber, which once formed a part of it, has been cut off, the house burned, or the mill washed away. He takes the land as it is, and, if there is no fraud, has no claim because of any apparent deterioration the property may have previously undergone. Most of the cases which we shall have occasion to cite will be found to have a direct bearing in support of this general position.
Property conveyed, passes, with all the incidents then rightfully belonging to it, or actually and usually enjoyed with it at the time of the conveyance, so far as they are necessary to the full benefit and perfect enjoyment of the property, without any specification of them, and without the usual phrase, “ with all the privileges and appurtenances to the same belonging.” “ Lex est, euicunque aliquis quid eoncedit, concederé videtur et id, sine quo res esse non potuit.” Lyford’s Case, 11 Co. 52. This position is supported by a great number of cases, never contradicted or questioned. It will be sufficient for our present purpose to cite some cases which relate to mills and streams, the immediate subject of inquiry in this case. They support the principle that a conveyance of a mill, or of land on which a mill is situate, carries with it, as incidents of the mill, the right to raise the millpond, and to flow the lands above as high as the dam has been usually kept up, and to maintain the dam and floom which are necessary to support the water at that height, and to support and use the pentstocks, aqueducts and channels which are necessary to convey the water to the mill, and the channels and race-ways which are necessary to conduct the water from the mill to the [496]*496stream below, in the manner in which they have been kept and used immediately previous to the conveyance, so far at least as the grantor has a right to convey such privileges. Shep. Touch. 89; Nicholas v. Chamberlain, Cro. Jac. 171; Vickary v. Buswill, 1 Shep. 289; Preble v. Reed, 5 Shep. 169; Hathorn v. Stinson, 1 Fairf. 224; Wetmore v. White, 2 Caine. Ca. 87; Leroy v. Platt, 4 Paige 77; Burr v. Mills, 21 Wend. 290; New Ipswich Factory v. Batchelder, 3 N. H. Rep. 190; Whitney v. Olney, 3 Mason 280; Gibson v. Brockway, 8 N. H. Rep. 465; Pettee v. Hawes, 13 Pick. 323; Blake v. Clarke, 6 Greenl. Rep. 436; Oakley v. Stanley, 5 Wend. 523; Kilgour v. Ashcomb, 5 H. & J. 82; Canham v. Fisk, 2 Cromp. & Jer. 126; 2 Tyr. 185; Elliott v. Shepherd, 12 Shep. 371.
The same rule applies in the case of the reservation of a mill or mill privilege in a conveyance of land. Pettee v. Hawes, 13 Pick. 323; Jackson v. Vermilyea, 6 Cow. 677; Allen v. Scott, 21 Pick. 25; French v. Carhart, 1 Comst. 103; Shep. Touch. 100; 1 Saund. 326, n. 6; Doud v. Kingcote, 6 M. & W. 197; Hinchcliffe v. Kinnout, 5 Bing. N. C. 1.
These cases are usually supported by the doctrine of implied grant, and may well stand upon that ground. They all support the position we have stated, that as to the incidents of real estate, deeds are to be construed with reference to the state of the property at the date of their execution; and this as well as to what is impliedly granted as to that which is expressed.
Our next position is, that property conveyed passes in its existing state, subject to all existing easements and burdens of a similar nature, in favor of other lands of the grantor, which are apparent, and which result naturally from the relative situation of the land, and from the nature, construction and intended use of the buildings, mills, &e., upon it, and their situation and connection with other property as they were usually enjoyed at the time of the conveyance. We propose to advert to the authorities upon this point more at length, because, although there is a series of decisions for several centuries back, all, as we regard them, tending to support the above position, few if any of them are [497]*497distinctly placed upon this broad ground, while many of them rest upon the once fashionable refinements of unity of possession, revivor and extinguishment.
And first, the cases heretofore cited are regarded as affording a clear support to this position upon the view we take of the nature of easements connected with the flow of water. Every easement of this class necessarily implies a duty upon the owner of the servient tenement, and every such duty implies a corresponding right in that owner. Thus the owner of land upon a stream has an easement upon the land above, that the water of the stream shall flow down upon his land at a certain place, at a certain level, and in a certain quantity. This right imposes upon the owner of the land above, the duty and obligation of suffering the water to flow agreeably to this privilege of the owner below; and it confers upon the same owner the right to discharge the water in that place and in that way, and imposes upon the owner of the land below the duty and obligation to receive the water in that place and in that manner. These rights and duties are reciprocal, and necessarily coexistent. The creation of one necessarily creates all the others. If one estate has an easement upon that above, to discharge the water in a particular manner, the estate above has a reciprocal easement upon that below, to receive the water in that particular manner. Each estate is in turn the dominant tenement, as to the easement from which it derives a benefit, and the servient tenement, as to the corresponding easement of which the other estate has the advantage. Thus if a man has a dam extending across a stream, with a mill on each side of it, and he sells to another person one mill, with the land on which it stands, without specifying or reserving any incidental rights, the purchaser of the mill has, agreeably to the cases before cited, the right to keep the water raised to its usual height. The grantor is bound to permit the water to flow at the height which is necessary to operate the mill. He cannot build a dam to prevent such flow of the water. He cannot remove his part of the dam and thus prevent it; but, as a necessary consequence, he has the reciprocal easement upon the land he [498]*498has conveyed — the right to require the purchaser to receive the water at the level he is bound to discharge it, and to do no act by which this right may be impaired; which is, in effect, that the purchaser shall maintain the water on his part at the same level his grantor is bound to keep it, of which the mill he has retained will of course have the benefit; and if the purchaser opens his gates, or removes his dam, and thus permits the water to flow at a less height, he is answerable to his grantor for diverting the water. The case last supposed is, as to this point, the precise case of Runnels v. Bullen, 2 N. H. Rep. 532. The result of this view is, that in every case where there is an implied grant of an easement in favor of the grantee of a mill or water privilege, the same grantee takes the mill or privilege, subject to the corresponding easement in favor of the grantor. If the one cannot divert the water from the mill he has granted, the other cannot obstruct its flowing to the mill in the usual and rightful manner at the date of the conveyance. This is a result that cannot be explained upon any doctrine of implied grant, and if implication is to be resorted to, it is the case of implied reservation. All the cases cited then, in our view, go to establish the position that wherever an easement is granted, either expressly or by implication, connected with the flow of water, there is an implied reservation of the corresponding and reciprocal easement upon the estate conveyed. From which it follows that the idea advanced in some books, that there can be no implied reservation, (see Burr v. Mills, 21 Wend. 290,) is entirely without foundation ; that the reverse is true, and a reservation of easements is necessarily implied in every case where easements of this class are either expressly or impliedly granted. This, it will be seen, upon consideration, is but another form of setting forth the position we are now discussing, that property conveyed passes in its existing state, subject to all existing easements and burdens of a similar nature, in favor of other lands of the grantor which £ire apparent, and which result naturally from the relative situation of the land, and from the nature, construction and intended use of the buildings, mills, &c., upon it, and their situation and con[499]*499nection with other property as they were usually enjoyed at the time of the conveyance.
The following cases are regarded by us as directly supporting • this doctrine:
11 H. VII. 25, (1496,) 1 Bro. Ab. 324. A man having two tenements, adjoining to one of which there is a gutter leading through the land of the other, sells one tenement to one person, and the other to another, it was held the easement of the gutter continued. It would have been otherwise, if before the conveyance. the owner had broken the gutter.
Nicholas v. Chamberlain, Cro. Jac. 121, (1607.) It was held by all the court, upon demurrer, that if one erect a house, and build • a conduit thereto in another part of his land, and convey water by pipes to his house, and afterward sells the house with the appurtenances, excepting the land, or sells the land, reserving to himself the house, the conduit and pipes pass to the house.
This case is quoted as sound law by Lewis, J., in Jackson v. Striker, 1 Johns. Ca. 291, and by Cowen, J., in Burr v. Mills, 21 Wend. 296, though the two cases, as to this point, are in direct conflict.
Sury v. Pigott, Palm. Rep. 444, (1626); S. C., Latch, Rep. 153; Poph. 166; 3 Buls. 339; Noy 84; W. Jones 145. One owned a rectory, to which there was a watering place, supplied by a stream which flowed from a brook through his hop-yard. He sold the rectory to one, and the hop-yard to another. Afterward, the owner of the hop-yard obstructed the stream, and the court held the easement of the stream remained.
Doddridge, J., put this case: One having a mill, had a watercourse to it over his own land, and sold part of the land where the water-course run; and then he says: For the necessity, (we should say, from the nature of the case,) the water-course remains to the vendor, and the vendee cannot stop it.
Hazard v. Robinson, 3 Mason 272. One had two mills. He sold the lower mill, with all the privileges and without reservation, and afterward sold the upper mill. The owner of the [500]*500lower mill raised his dam, and thereby obstructed the upper one. It was held the grant .of the lower mill conveyed it, with such privileges as to the dam and water as were at that time used and appropriated to it.
The case of Sury v. Pigott and Nicholas v. Chamberlain were cited by Story, J., at much length, and approved.
Kent, (3 Cowen 449,) says: “ Nor is a water-course extinguished by unity of possessionand this from the necessity of the case and the nature of the subject. This was settled after a very elaborate discussion, in Sury v. Pigott; and that case was accurately examined and deliberately confirmed in all its parts in Hazard v. Robinson.
Cary v. Daniels, 8 Met. Rep. 466. The owners of two mills on the same stream, conveyed the upper mill and privilege, and land, warranted free of incumbrance. They afterward conveyed the lower mills. The lower mill, at times, threw back water upon the upper. Held, that the purchaser took the upper mills and privilege as they existed, and were modified and appropriated by the lower dam when it was conveyed.
Whitney v. Eames, 11 Met. Rep. 517. The doctrine of Gary v. Daniels was again considered and approved; and it was held that the purchaser of an upper mill privilege would purchase subject to the actual appropriation [of the water to the use of the vendor’s mill below,] and if there were no reservation in terms by the vendor, he would retain the privilege [below] as actually appropriated and used.
Tucker v. Jewett, 11 Conn. 311. It was held that several tenants in common of mills and land, making partition by releases in which there was no reservation, the owner of the mill had the right to flow the water upon the land he had released, to the height it had been used to flow, and that the mill-owner, having afterward conveyed the land above his mill without any reservation, could not be disturbed in flowing the water to its usual height.
Seibert v. Levan, 8 Barr. 383, [9 U. S. Dig. 133.] Where a tenant in fee erects a mill, with a dam and race to supply the [501]*501same, and afterward conveys that part of his land whereon are the dam and race, without any express reservation as to them in his deed, his grantee takes the land, burdened with an easement in favor of the grantor, which the grantee is not at liberty to disturb.
The cases of Randall v. Silverthorn, 4 Barr. 173, [7 U. S. Dig. 159,] and Fry v. Whitman, 7 Barr. 440, [8 U. S. Dig. 368,] in effect support the position we are discussing, though we might not assent to some views stated in the Digest as presented by the court.
Perry v. Parker, 1 W. & M. 280. When the same owner of land with a mill privilege conveys them to different persons, it will be presumed that each is to preserve the privileges used with it before the junction of the estates, unless some change distinctly appears.
French v. Carhart, 1 Comst. 96. A. conveyed to B. land upon a stream which was flowed by his mill below, “ saving all creeks and streams of water P It was held, better to give effect to the spirit of the instrument and the intention of the parties, that the grantor reserved the use of the water as he was then using it, and that the court were bound to presume such to have been the intention, unless restrained by express words.
This case seems substantially to overrule Burr v. Mills, though not in terms. In that case there was no reservation.
Kilgour v. Ashcombe, 5 H. & J. 82, [cit. Ang. W. C. 169.] In a division of real estate among heirs in Maryland, where a mill was assigned to one, and part of the dam is on land assigned to the other, it was held the assignee of the mill has a right to use the mill and dam in the same way, and to the same extent, as they had been used by the deceased in his lifetime.
Busdick v. Glasko, 18 Conn. 494, [8 U. S. Dig. 366.] A. and B. were owners of mills on the same dam. B. raised the dam on his side so as to throw the water upon A.’s wheel. It appeared that both parties claimed under the same title, and there was no special reservation as to this matter. Held, A. could maintain his action. Ang. W. C. 414.
[502]*502It would seem the principle involved here was the same as in Runnels v. Bullen — that the parties were entitled to the water, uti currere solebat.
New Ipswich Factory v. Batchelder, 3 N. H. Rep. 190. The owner of a mill and race-way sold the mill to one person, and afterward the land in which the race-way was, passed to another. Richardson, C. J., says: “ As both these parties claim under the same person, it seems to us that, as between them, this raceway is to be considered as the natural channel of the river.”
Runnels v. Bullen, 2 N. H. Rep. 532. One owning a dam across a river, with mills on each side, conveyed to the defendant’s grantor the north half of the dam, and the mills on that side, with the privilege of. taking the water from any part of the north half of the dam for the use of the grantee, &c., without any reservation. He afterward conveyed the south half of the dam, and the mills on, that side, to the .plaintiff. The defendant having another mill below, kept the gates of his half of the dam permanently raised, by reason of which the plaintiff lost the use of his mill.'. It was held that the defendant had no right to raise .his,- gafes,"and. lower the water of the mill-pond below the usual -level* to’the-injury of the plaintiff. In effect, this decision was, that the defendant took his dam and mills subject to the easement; for the. benefit of the plaintiff, of keeping up the water of the pond to its usual height.
The following cases seem to be in conflict with the preceding decisions, and, to some extent, with the principle we have cited them to sustain: Preble v. Reed, 5 Shep. 173; Johnson v. Jordan, 2 Met. 234; Manning v. Smith, 6 Conn. 289; Burr v. Mills, 21 Wend. 290; and see Leroy v. Platt, 4 Paige 77. We regard the cases in Massachusetts, Connecticut and New-York, as substantially overruled, as to this .point, by the later decisions in the same States, to which we have referred. They are decided upon other, grounds, not directly involving the principle we have maintained. And upon all the cases we have found, bearing upon the question and relating to water rights, we think the [503]*503weight of authority greatly preponderates in favor of the view we have taken.
The following cases, relating to other easements, go strongly to sustain the same view:
Robins v. Barnes, Hob. 131; Moor 866; Rolle’s Ab. 936; Ext. Mar. Dic. 7. Where a party had wrongfully obstructed a window in a house, which he afterward purchased and sold to another, it was held that the purchaser could not abate the nuisance, “being that he (the purchaser) ought to take it (the house) in such plight as it was at the time of the grant made to him.” “ The court agreed that though one of the houses had been built overhanging the other wrongfully before they came into one hand, yet after, when both came into the same hands, the wrong was purged, so that if the houses came afterward into several hands, yet neither could complain.”
But note, (says the reporter,) that there is a great difference between interests and profits, as rents, commons, &c., and bare easements, such as are lights, air, gutters, stillicidia and the like; for though, while they (the tenements) are in one hand, they (the lights, &c.,) may be stopped or foredone, because a man cannot be said to wrong himself; yet, if they (the tenements) be divided, things of that nature [still in being] do revive, because they are of no less use of themselves in one hand than in divers, being equally, [rebus stantibus, in the same use and occupation,] necessary for the several houses to which they belong. But clearly, if even such things be foredone or altered while they are in one hand, and so being, the houses be again divided, they cannot be restored by law, but must be taken as they were at the time of the conveyance.
Palmer v. Fletcher, 1 Lev. 122; 1 Sid. 167; 1 Keb. 153, 625, 794. The opinion of Tevisden, J., was, that if a man erect a house on his own land, and afterward sell the house to one, and the land to another, whether the house be sold first or afterward, the vendee of the-land cannot stop the lights of the house; and cited a case to be so adjudged. Kelynge, J., contra.
Reviere v. Bower, 1 Ry. & Mo. 24. The plaintiff was owner [504]*504of a house which he divided into two tenements. One of which he leased to the defendant, and he occupied the other himself.' The defendant obstructed a window which the plaintiff made in his own tenement shortly before the lease to the defendant. Held, that the action was maintainable against the tenant for obstructing a window in the landlord’s house, which was there at the date of the lease, though lately made, and though there was no stipulation in the lease against the obstruction.
Compton v. Richards, 1 Price 27. Held, that if the owner of two houses, one of which is unfinished, but the .places of the windows are apparent, sell the same to different persons at the same time, the purchaser of the finished house cannot place an obstruction in the way of the proposed windows of the other house — the sale being upon an implied condition that those windows should not be obstructed.
The cases of ways of necessity are within the same principle. They are burdens of the nature of easements, which are apparent, and which naturally result from the relative situation of the property. 2 Bro. Ab. 104, Nuisance 11; 2 Rolle’s Ab. 60, Grant, Z, 17, 18; Jordan v. Atwood, Ow. Rep. 121; 2 Lutw. 111; Parker v. Welsteid, 2 Sid. 39, 111; Dutton v. Taylor, 2 Lutw. 1487; Bulkley v. Coles, 5 Taun. 311; Howton v. Frearson, 8 D. & E. 50; Clark v. Rugge, Cro. Jac. 170; Oldfield’s Case, Noy 123; 1 Wm. Saund. 323.
Ways of necessity are usually spoken of as exceptions to the general rule that easements are extinguished by unity of possession. 3 Kent’s Com. 449; Hazard v. Robinson, 3 Mason 276. But it seems more correct to regard them as new rights, impliedly granted or reserved by the conveyance. Grant v. Chase, 17 Mass. 447.
The principle that such ways of necessity are not extinguished by unity of possession, affords a clear solution of this class of cases, as far as it applies; but it is by no means broad enough to reach all the cases. It is immaterial whether there has ever been an easement of the kind before. The way is implied, not because an easement has previously existed, but because without [505]*505it the grantee cannot have the enjoyment of the thing granted; or the grantor would be deprived of the enjoyment of the property which he retained.
The doctrine of implied grant of whatever is necessary to the enjoyment of the principal thing granted, would apply to one large class of these cases; but it has no application to the cases where a way of necessity is reserved for the benefit of the grantor, by the law, without any stipulation of the parties, across the property granted to the land which he has retained. To these a doctrine of implied reservation is as indispensable as that of implied grant is to the others; and we think all the cases to which we have referred sustain our general position, that easements are in all cases impliedly conveyed or reserved in favor of other lands of the grantor, without any special words, whenever the burden is apparent, and naturally results from the relative situation of the property, if land alone, or from the nature, construction and intended use of buildings and mills, and their situation and connection with other property.
Agreeably to these views, we hold that the right to use and enjoy the race-way from the mill to the stream below, was impliedly reserved to the plaintiff in his deed to Kidder; ox*, in other words, that the land passed to Kidder, subject to such use and enjoyment by the plaintiff; and the defendants are consequently liable for interfering with that right.
The doctrine of the extinguishment of easements by unity of possession, and that of the revivor of easements, of necessity, upon the division of the estates from and to which the easement is due, can have no application in this case, because there was no easement in existence at the time when the plaintiff purchased the interest of the Parkers in the mills, and in the meadow below.
It is clear upon the decisions, which it is not necessary here to question, whatever doubt there might otherwise be upon the points, that an easement is an incorporeal hereditament, which lies in grant at common law, (2 Bla. Com. 317; Co. Litt. 172;) and that it is such an interest in lands as cannot pass without [506]*506writing, by the statute of frauds. Hewlins v. Shippam, 5 B. & C. 221; Fentiman v. Smith, 4 East 107.
The change of the channel, therefore, by the verbal agreement of the parties, gave to the plaintiff no rights, but merely at the pleasure of the parties. The consent of the Parkers was of the nature of a mere license, which was revocable at any moment. The interest of the plaintiff in the race-way was of the nature of an estate at will, at most, liable to be terminated at any time. It of course ceased upon the purchase of the property by the plaintiff, because the owner of property cannot be tenant at will to himself, nor act by any license in regard to it but his own pleasure; but it was not extinguished as an easement, because no such interest had ever existed.
Independently of the technical notion of the common law, which requires all grants of incorporeal hereditaments to be in writing, and of the statute of frauds, which requires all creations and assignments of any interests in land to be in writing, we suppose there can be no doubt that, by a common agreement of all parties interested, though merely verbal, any change may be made in the actual state of property, and easements created as necessary consequences of that change; as, for example, a new channel may be made for a stream, the water turned into it, and the old water-course abandoned or obliterated, and the new channel would thenceforth be the only channel; and as to all the parties, and those who claim under them, it must be regarded as the natural channel, with all the easements and incidental rights which would belong to it if there never had been any other.
As, then, the owner of land having the only interest in the matter, can make no grant to himself, and can execute no instrument in writing by which a change in the property can be made while he remains owner, and as he has the right, by virtue of his ownership, to make any disposition of the property which he pleases, it seems to follow that if he does make any change in the property, those who claim under him, and derive their titles from him, must take the property in the state it is in at the time, [507]*507precisely as if it had been its natural state, and no other had ever existed.
In accordance with this view is the principle borrowed by Gale & Whatley, in their treatise on easements, from the French law:;That the disposition of the property made by the owner of two" estates constitutes a valid title to the easements created by him, which' are apparent when the estates are again separated and pass into different hands. Gale & What. Easements 38, &c.
Art. 694 of the Code Civil, states the rule of the French law thus: “ If the proprietor of two estates, between which there exist the apparent marks of a servitude, dispose of one of the estates, without his conveyance containing any stipulation or reservation relative to the servitude, it continues to exist, actively or passively, in favor of the estate sold, or upon that estate.” All the authorities to which we have referred support this doctrine as the true rule of our law, though they do not, so far as we recollect, in any instance allude to the principle in terms.
The same decision, which we feel compelled to make as to this case, on general principles, must also be made upon the peculiar circumstances of the case itself. Nothing is clearer than that in giving construction and effect to a contract or conveyance, we are to take into consideration the situation of the parties and of the property, and all the provisions and expressions of the instrument. The object # to ascertain the true meaning and real intention of the parties. Here, then, the plaintiff was the owner of a valuable mill, with a race-way to conduct the water from the mill in the most direct way to the stream below. This race-way was constructed by the consent of all parties interested, at much expense, because it was regarded as necessary for the operation of the mill in the most advantageous way. It had been in use for several years, and until the original channel had become to a great extent obstructed, and could not readily be restored. Under these circumstances, the plaintiff conveyed a portion of his land, in which this race-way is situate, to Kidder, and in describing the land conveyed, says — “bounding on the saw-mill [508]*508brook,” -which it is admitted is this artificial race-way, and “ on the Bridge Meadow Brook,” which was the original channel; and the deed contains no reservation or stipulation looking to any change proposed or feared of these water-courses. Now we think the mention of this race-way as the saw-mill brook, is a recognition of it as being, as between these parties, the brook-— the natural channel — since that is the natural force and signification of the word brook, and is entirely equivalent to an agreement that, as between these parties, this race-way is to be regarded as the natural stream.
It might well be contended that there was an implied covenant from the language of this description, that the mill brook did in fact run at the places described, so that the purchaser would have the benefit of it there. Thus it has been held that where land is conveyed as bounded upon a way, there is an implied covenant that there is such way. Parker v. Smith, 17 Mass. 413; Livingston v. Mayor, &c.; of New-York, 8 Wend. 85; Emerson v. Wiley, 10 Pick. 310.
It is very apparent that the right of the defendants to require that the mill brook should remain in its present channel, may be as important and valuable to them as it is to the plaintiff that it should remain unobstructed. A change might compel them to substitute for the small culvert at the original channel, a wider bridge, sufficient to carry the entire flow of the stream. Such a change they would be likely to resist, and upon the ground that the plaintiff has, by his description, made the race-way, as between them, the natural channel of the stream. If that is a correct position, as we think it, the same conclusion must follow when the rights and duties of the plaintiff are in question.
Either of the views suggested furnishes an answer to the argument drawn from the covenant against incumbrances. Nothing which constitutes a part of the estate, or which, as between the parties, is to be regarded as an incident to which the estate is subject, can be deemed an incumbrance. Pettee v. Hawes, 13 Pick. 323. See Cary v. Daniels, before cited.
We are of the opinion, then, that upon the case stated, the [509]*509plaintiff is entitled to recover damages for the obstruction of the ■water, to be assessed by a jury.
In the conclusions to which we have, arrived, a's to the decision of the case before us, the court are agreed. Perhaps some of the views suggested should be considered rather as those of the judge who delivers the opinion — the examinations of his brethren not having led them over the same ground.
