afterward drew up the opinion of the Court. We are not called upon to determine whether the bridge and the mill which the defendants and those under whom they claim have built, are public nuisances or not. If, contrary to probability, a grand jury should be found, after the public have enjoyed the bridge for more than forty years, to present it as a public nuisance, it will be time enough then to determine whether it be so or not.
But the case we are to determine is, whether the plaintiff can, upon the facts found in the case, recover against the de fendants for a private, nuisance, which is alleged to arise from the dam of the defendants.
If the defendants should produce a deed under the hand and seal of the plaintiff, made before the bridge was built, which,for valuable consideration, purported, so far as the plaintiff was concerned, and so far as all who should succeed and become privy in estate might be concerned, to grant to the defendants and their assigns full liberty to make and continue the bridge and dam, to stop the tide water to work a mill to be built, it would be very clear that the plaintiff could not legally complain of the damage which should be occasioned by such dam or bill, to his estate. He would unquestionably be estopped, and could neither maintain an action for damages, nor remove the obstructions so raised and continued according to his own deed.
*303If the creek over which the dam should be constructed were technically to be considered as navigable from the sea, and such obstruction might be considered as a public nuisance upon a highway, and the defendants were answerable accordingly to the public, yet by the legal construction of such a deed, he could make no legal claim, and those who should represent him in respect to his estate, could make no legal claim for damages from such erections.
Now the legal result from the facts which are found, is as clear and conclusive evidence of an assent, as if it were proved by the deed of the plaintiff.
The existence of the facts might have been controverted The plaintiff might have denied that the bridge was built more than twenty years ago. He might have denied that the defendants had had a peaceable possession, and he might have denied that it was an adverse possession, and have proved, if the truth would have permitted, that the enjoyment was to be at the will of the plaintiff and of those who should have his estate, or that it was for a limited time which had passed. These things the plaintiff might have contested; but these things being" proved, he can no more deny nor controvert the legal result which establishes the defendants’ right to the easement, than the heir could deny the right of a widow to have her dower in the lands of which her husband died seised. This is what in the civil law is called prcesumptio juris et de jure. It is a rule or conclusion of the law, which ascertains the rights and duties of the respective oarties as certainly and incontestably, as if they were expressed in a deed or by legislative enactment.
Now in the case at bar it appears, that the right to the easement was claimed and exercised by the defendants, in the presence of the plaintiff, thirty-five years ago, and that it has been exercised peaceably and continually, and adversely, during all that time. The damage done to the plaintiff’s lands and estate was as great at the first, as at the last of that period, when the plaintiff undertook himself to put up his mill upon the creek above the defendants’ mill. Until that time no complaint ór interruption is made on his part ; and to this day, more than forty years from the building of the bridge, no complaint has been made on the part of the Commonwealth.
*304It follows, necessarily, as a rule of law, that as between ¡he parties, the right of the defendants to the easement as they and those under whom they claim have enjoyed it, is fixed and established against any claim of damages or interruption by the plaintiff, and those who may derive title under him.
We are all of opinion, that the plaintiff must be nonsuit.
