CHAPTER XX.
MORE WINTER TREES: THE FIRS AND THE SPRUCES.
There were some beautiful evergreens on the lawn at Elmridge, and, although the foliage seemed dark in summer, it gave the place a very cheerful look in winter, when other trees were quite bare, while the birds flew in and out of them so constantly that spring seemed to have come long before it really did arrive.
AMERICAN WHITE SPRUCE.
"This balsam-fir," said Miss Harson as they stood near a tall, beautiful tree that tapered to a point, "has, you see, a straight, smooth trunk and tapers regularly and rapidly to the top. You will notice, too, that the leaves, which are needle-shaped and nearly flat, do not grow in clusters, but singly, and that their color is peculiar. There are faint white lines on the upper part and a silvery-blue tinge beneath, and this silvery look is produced by many lines of small, shining resinous dots. The deep-green bark, striped with gray, is full of balsam, or resin, known as balm of Gilead or Canada balsam, and highly valued as a cure for diseases of the lungs. The long cones are erect, or standing, and grow thickly near the ends of the upper branches. They have round, bluish-purple scales, and the soft color has a very pretty effect on the tree. They ripen every year, and the lively little squirrel, as he is called, feasts upon them, as the crossbill does on the cones of the stone-pine. But the mischievous little animal also barks the boughs and gnaws off the tops of the leading shoots, so that many trees are injured and defaced by his depredations."
"He is a lively little squirrel," observed Malcolm. "How he does race! But he doesn't gnaw our trees, does he?"
"No, I think not, for he prefers staying in the woods and fields; but fir-woods are his especial delight. Our balsam-fir is the American sister of the silver fir of Europe, both having bluish-green foliage with a silvery under surface, in a single row on either side of the branches, which curve gracefully upward at the ends. The tree has a peculiarly light, airy appearance until it is old, when there is little foliage except at the ends of the branches. The silver fir is one of the tallest trees on the continent of Europe, and it is remarkable for the beauty of its form and foliage and the value of its timber."
"I know what this tree is," said Clara, turning to an evergreen of stately form and graceful, drooping branches that almost touched the ground: "it's Norway spruce. Papa told me this morning."
