This is a native of the coldest portions of the continent. It rises to a height of forty feet, with a diameter of from fifteen to eighteen inches; it tapers very rapidly from the base up; the wood is white, soft, and of no strength; the resin is deposited in clumps and blisters on the trunk and branches, and is used for medicinal purposes. It is passable as an ornamental tree, but soon becomes old and decrepit and loses its branches and leaves.
This is a variety that is found from the New England States southward. It has the general characteristics of the rest of its species, but is not so hardy. It has smaller leaves, and more numerous and smaller cones.
