Covered with forests.
1821. A country universally forested, as North America was antecedently to the colonization of it by Europeans, would be absolutely uninhabitable to the end of time . By this curious process [of slow decay] forested grounds are kept always healthy; and are not less friendly to the human constitution than those, which are under the most perfect culture.T. Dwight, Travels, iii. 253.
1865. A comparatively small surface of this vast range of wild country has been forested.Qu. Review, July, p. 18. (N.E.D.)
