¶1 Under the common law, one had the right of “ distraining another’s cattle damage feasant, that is, doing damage, or trespassing, upon his land.” 3 Bl. Com. 6. A similar right is given by our statute which provides that “ a person may impound any swine, neat cattle, horses, sheep, or other creatures doing damage in his inclosure.” P. S., c. 144, s. 1. Both under the common law and the statute, the essential prerequisite to the right to impound is that the animals must be doing damage when taken. The finding of fact that the calves when impounded were doing damage in the defendant’s inclosure is conclusive in favor of lfis right to impound them. Although the damages were small, yet they were actual, and therefore were sufficient to justify the defendant in impounding the ammals.
¶2 The case of Osgood v. Green, 33 N. H. 318, relied upon by the plaintiff, is not in conflict with the views here expressed, because in that case there not only was no finding that the animal im *297 pounded was doing damage when taken, but, on the contrary, there was an express finding that no damage was done.
