after stating the facts: The defendant, after testifying on his examination in chief, that he had, as tenant-for-life of Mrs. Emily Floyd, used the land as a prudent man would his own, stated further, without objection, that at the time when it was alleged he had incurred liability for waste he believed he was the owner in fee-simple, and had exercised the same care in the management of it that he had exhibited in dealing with his own land.
The gravamen of the complaint is that the defendant unlawfully cut down and destroyed valuable timber trees. The defence is that he cut down trees in clearing such a portion of the wood land as a prudent owner in fee, observing the accepted rules of good husbandry, would have cleared for cultivation, and was not therefore answerable to the remaindermen for .voluntary waste.
The jury in responding to the issues would be required to pass upon the question whether the defendant inflicted lasting injury to the inheritance in preparing timbered land for cultivation, or whether the cutting of trees was merely incidental to the opening for cultivation of such portion of the wood land as, in the exercise of reasonable care, he would have cleared had he been the owner in fee. He had been allowed to testify, without objec ion, that he did not believe at the time that he was only a life-tenant. Whether this testimony was competent or not, it was certainly not collateral. The defendant had been permitted to state his opinion as to the nature of his own estate in the land. He had, therefore, the benefit of whatever weight the jury might give to that fact in determining whether he was as careful as a prudent owner of the fee would have been in adjusting the proportion of cleared and wooded land.. Having testified, therefore, to an opinion which tended to corroborate his *96statement that in fact he managed the land as a skillful husbandman would his own, it was competent to contradict him by asking whether he knew certain facts inconsistent with such belief on his part, and then to put in evidence a verified answer filed by the witness embodying statements not reconcilable with his evidence. 1 Greenleaf on Ev., § 449; State v. Kirkman, 63 N. C., 246; Stephens’ Dig. of Ev., Art. 132. Collateral facts are such as are incapable of affording any reasonable presumption or inference as to the principal fact or matter in dispute. 1 Greenleaf, § 52. As we have seen, the opinion given in this case became important on account of its tendency to corroborate the evidence of the defendant upon the very question on which the finding of the jury depended, and the plaintiff could not refrain from contradicting it without peril The case, therefore, does not fall within the rule in reference to collateral matters. Edwards v. Sullivan, 8 Ired., 302. The belief that he was the owner in fee, if it existed, was calculated to stimulate, the defendant to exercise care in dealiug with the land. It was a motive to make him act the part of a prudent person holding the fee. Proof that he knew he had no more than a life-estate was evidence, if not of an incentive to commit waste, at least of the absence of any selfish motive for protecting the inheritance against injury.
We think, therefore, that there was no error in admitting the testimony, and the judgment is affirmed.
Affirmed.
