runs. Hendricks v. Johnson, 6 Porter, 472. Being owner of the land over which a stream of water flows, he has-the right to use the water, but as this-right is common to all the riparian owners, no one of them, by virtue of his title to the land and his-right to use-the water incident thereto, can claim to use the water so as to corrupt or impair its quality to the prejudice or injury of the others; Angel on Water Courses, 20; Howell v. McCoy, 3 Rawle, 256. The defendant, therefore, cannot claim the right to injure the water by virtue of any title to the land, from whatever source derived.-' It is true, he acquired the right to erect a mill on the creek, and to use the water for this purpose, but the rights of those below him forbade him so to constract it as to render the water impure, or to corrupt or injure its quality.
3. Nor do we think that the length of time,- during which the defendant has been permitted to let the saw-dust fall from his mill into the creek, can exempt him from the penalty- of the 4th section of the act of 1820,.if in truth the qualities of the water are impaired by it. In the case of Mills v. Hall, 9 Wend. 315, the facts were, that the defendant.had built a dam across • a stream, which it was alleged corrupted the atmosphere and affected the health of the plaintff and his family, and one of the grounds of the defence was that the dam had- been erected more than twenty years. The court said, that there could be no such thing as a prescriptive right to maintain a public nuisance, and although the dam may have been erected more than twenty years, and during all the time has rendered the adjacent country unhealthy, yet such length of time can form no defence to the right of the public to abate it, nor to an action at the suit of any one who has suffered by it, although such length of time would form a bar to any action to recover damages for overflowing the land of an adjoining owner by reason of the erection of the dam. Again, in the case of the People v. Cunningham, 1 Denio, 524, it is said, that no length H of time will enable a party to prescribe for a nuisance. See also Hey v. Sterrett, 2 Watts, 327.
4. It is not, however, necessary that we should assume the broad principle, that no length of time will justify the continuance of a nuisance. If it can be continued on the ground of the length of time that it has been permitted to exist or con
