But that which I believe yields a great deal of our turpentine, is the fir-tree or deal, which is a coniferous tree, evergreen, whose cones are of the lesser sort, having long leaves, either that whose leaves encompass and cover the branches, bearing long cones hanging downwards as she male fir-tree or pitch-tree; or that whose leaves grow from each side of the stalk, being more flat than those of yew, green on the upper side, and whitish underneath, furcated at the end, bearing cones shorter and thicker, growing erect, as the female fir-tree.
