This tree is extremely formal and regular in outline in almost every stage of growth; generally assuming the shape of an exact cone or pyramid of close foliage, of considerable extent at the base, close to the ground, and narrowing upwards to a sharp point. So regular is their outline in many cases, when they are growing upon favorable soils, that at a short distance they look as if they had been subjected to the clipping-shears. The sameness of its form precludes the employment of this evergreen in so extensive a manner as most others; that is, in intermingling it promiscuously with other trees of less artificial forms. But the Arbor Vit�, from this very regularity, is well suited to support and accompany scenery when objects of an avowedly artificial character predominate, as buildings, etc., where it may be used with a very happy effect. There is also no evergreen tree indigenous or introduced, which will make a more effectual, close, and impervious screen than this: and as it thrives well in almost every soil, moist, dry, rich, or poor, we strongly recommend it whenever such thickets are desirable. We have ourselves tried the experiment with a hedge of it about 200 feet long, which was transplanted about five or six feet high from the native habitats of the young trees, and which fully answers our expectations respecting it, forming a perfectly thick screen, and an excellent shelter on the north of a range of buildings at all seasons of the year, growing perfectly thick without trimming, from the very ground upwards. The only fault of this tree as an evergreen, is the comparatively dingy green hue of its foliage in winter. But to compensate for this, it is remarkably fresh looking in its spring, summer, and autumn tints, comparing well at those seasons even with the bright verdure of deciduous trees.
