The evidence leaves it entirely uncertain how long the alleged defect had existed. One witness testified that she “ had been through there Sunday night before, to church.” But she did not testify, and does not appear to have been asked, as to the condition at that time. If there was a defect the plaintiff was bound to show either that the defendant knew it, or in the exercise of reasonable care and diligence ought to have known of it in season to remedy it. Pub. Sts. c. 52, § 18. There was no evidence that the defendant knew of the defect if there was one and in the absence of evidence to show how long it had been there it cannot be said that the defendant ought in the exercise of reasonable care and diligence to have known of it and remedied it.

Exceptions overruled.
