The balsam fir is one of our most graceful trees, its rich dark green foliage and conical shape making it a rare combination of '' beauty in both form and color. The leaves are dark green above and silvery-white beneath, not more than half an inch long on the upper cone-bearing branches but some- limes more than an inch long on the older sterile boughs. The cones are from two to lour inches long, stand- ing erect on They are a rich purple and very resin- uus, the juice often exuding as viscid drops on the y»ung cones or remaining in dry hard masses on the old ones. The bark is densely covered with blisters and varies from thin smooth greenish or whitish in the young trees, to about half an inch thick and a rich brown on the older trunks. This tree grows on light, well-drained soil, wherever conifer forests are found across Canada to Alberta. It is replaced in the mountains bv other species. It grows rapidly and has been extensively used for ornamental planting, but is now being largely replaced for that purpose by more vigorous and longer- lived species from western .\merica and from Asia. The resinous juice collected from the blisters on the bark is sold under the name of Canada balsam, and used in microscopic. I'lc).
