erred in this respect. The rule is well settled that a party may abate a private nuisance upon his own motion, after notice, when necessary, provided he does so without disturbing the peace, does as little injury as possible, and removes so much of the thing only as causes the nuisance, whenever he can maintain an action for the injury caused thereby, though the damages resulting therefrom be nominal only : Angell, Water Courses, § 389 ;
Brown v.
Perkins, 12 Gray, 89 ;
Amoskeag Manf. Co. v.
Goodale, 46 N. H. 53. To make out a case of special injury to property from a nuisance, something materially affecting its capacity for ordinary use and enjoyment must be shown :
Sparhawk v.
Union Passenger Ry. Co. 54 Pa. St. 401. Thus, where a party erected a dam so as to flow backwater upon the land of another, it was held that injury would be presumed, and no special damage need be shown :
Woodman v.
Tufts, 9 N. H. 88. So, too, an infringement of a right which, if continued, would ripen into an easement, entitles the party injured thereby to nominal damages, for which he may maintaiman action without proof of special damages :
Tillotson v. Smith, 32 N. H. 90 (64 Am. Dec. 355) . An examination of the instructions refused will show that- they are not predicated upon the assumption that the. defendant sustained even nominal damages by the construction of the dam, or that the water flowed back upon his land so that if it were continued it would ripen into an easement. In the light of the rules to which attention has been called, if the defendant sustained no injury he could not maintain an action, and, if unable to maintain an action, he could not justify the demolition of the dams. Hence the instructions requested were immaterial, and no error was committed in refusing to give them.
The transcript shows that other exceptions were taken by the defendant at the trial, but, .not being urged at the
