Some of the most beautiful forests in high latitudes consist of White Canoe-Birches.  We see them in Massachusetts only in occasional groups, but farther north, upon river-banks, they form woods of considerable extent and remarkable beauty; and with their tall shafts, and their smooth white bark, resembling pillars of marble, supporting a canopy of bright green foliage, on a light feathery spray, they constitute one of the picturesque attractions of a Northern tour.  Nature seems to indicate the native habitat of this noble tree by causing its exterior to bear the whiteness of snow, and it would be difficult to estimate its importance to the aboriginal inhabitants of Northern latitudes.  Yellow Birch woods are not inferior in their attractions:  individual trees of this species are often distinguished among other forest timber by extending their feathery summits above the level of the other trees.

The small White Birch is never assembled in large forest groups.  Like the Alder, it seems to be employed by Nature for the shading of her living pictures, and for producing those gradations which are the charm of spontaneous wood-scenery.  In this part of the continent, a Pitch-Pine wood is commonly fringed with White Birches, and outside of these with a lower growth of Hazels, Cornels, and Vacciniums, uniting them imperceptibly with the herbage of the plain.  The importance of this native embroidery is not sufficiently considered by those industrious plodders who are constantly destroying wayside shrubbery, as if it were the pest of the farm,—­nor by those “improvers,” on the other hand, who wage an eternal warfare against little spontaneous groups of wood, as if they thought everything outside of the forest an intruder, if it was planted by accident, and had not cost money before it was placed there.  Give me an old farm, with its stone-walls draped with Poison-Ivy and Glycine, and verdurous with a mixed array of Viburnums, Hazels, and other wild shrubbery, harboring thousands of useful birds, and smiling over the abundant harvests which they surround, before the finest artistical landscape in the world!

Pines are remarkably social in their habit, and cover immense tracts in high latitudes, extending southward, on this continent, as far as the very boundary of the tropics, where they are found side by side with the Dwarf Palm of Florida.  But in the region of the true Palms the Pine is wanting.  It is worthy of remark, however, that in the fossil vegetation of the Eocene world these two vegetable tribes are found associated.  This fact, it seems to me, should be attributed to the mixing of the mountain Pines with the Palms of the sea-level, during that revulsion of Nature by which they were hurled into the same chaotic heap.  We are not obliged to infer from their contiguity in these geological remains, that the two species ever flourished together in the same region.
