2.Where it has been protected by a substantial enclosure, except as provided in subdivision one of section five hundred forty-three of this article.
3.Where, although not enclosed, it has been used for the supply of fuel or of fencing timber, either for the purposes of husbandry or for the ordinary use of the occupant.
