Peaslee, J.

The defendant advances three grounds for her motion in arrest of judgment. The first claim is that the declaration is fatally defective in that it does not allege the plaintiff’s freedom from contributory negligence. Such allegation is not needed. Smith v. Railroad, 35 N. H. 356; Corey v. Bath, 35 N. H. 530, 548. There is nothing peculiar about the doctrine of contributory negligence as applied in cases under this statute. It is the ordinary rule “ that the party injured is not entitled to recover if his own negligence contributed to the injury.” Quimby v. Woodbury, 63 N. H. 370, 374. The rule that formal allegation of the plaintiff’s freedom from fault is unnecessary has become so well understood in this state that in a recent case the proposition was conceded by counsel and was adopted by the court without question or elaboration. Wheeler v. Railway, 70 N. H. 607, 615.

It is next urged that the declaration is so indefinite that it cannot be ascertained whether the plaintiff seeks to recover under section 9, chapter 118, of the Public Statutes, or under section 14, chapter 60, of the Laws of 1891. The last mentioned statute provides for recovery in an “ action of tort,” and so the plaintiff has declared. While it is true that there was no such action at common law, it is provided for by the codes and statutes of many states. It was competent for the legislature to so name the action for this particular wrong. Orne v. Roberts, 51 N. H. 110. Having so named it, and the action having been brought under that name, the declaration would seem to inform a person of ordinary Intelligence that the plaintiff' sought to recover under this statute, *536 and not under another act into which this name for the form of action has not been incorporated.

Lastly, it is argued that the double damages provided for by the act cannot be recovered because not in terms declared for. This part of the statute is of course merely the rule of damage in the particular case. It involves no question of fact, but relates solely to the ministerial act of applying the statute to the facts found. Jaquith v. Benoit, 70 N. H. 1. Having been appraised by the declaration in an action of tort that the plaintiff sought to recover under the statute providing for double damages, the defendant was sufficiently informed that the rule of damages laid down therein would be applied.

Exception overruled.

All concurred.
