EVERGREEN TREES.

The Hemlock Spruce. Abies Canadensis . — Tlie hemlock, 
common in all portions of our Union, possesses features of ele- 
gance and beauty unlike that of any other hardy variety. When 
standing alone, or on the outskirts of small groups, its dark yet 
loose-looking foliage, hanging in pendulous tufts from its pecu- 
liarly graceful, half-curving branches, renders the tree one of the 
most ornamental, and suited to a place in decorating the grounds 
of almost every residence. It is a tree that bears the shears well, 
and is therefore adapted to hedge or screen planting. When 
grown in the nursery, it is no more difficult to transplant than 
other evergreens, although it has been declared very sensitive of 
removal — probably by those who had no experience except with 
its removal from the woods. It is, as we have said, a beautiful 
tree for the open lawn, but it lacks stateliness to adapt it for 
position near the main residence or buildings. 
Arbor Vel®. Thuja. — The American arbor vitse — thuja 
occidentals — frequently, and perhaps more generally, called white 
cedar, is one of our most valuable evergreens. Of a regular 
formal outline in its growth, from the young plant to the tree, 
it can rarely be used in grouping ; but as a single point tree, or 
for screen belts and hedges, it is one of the most desirable. It 
may be grown to form a perfect wall or screen thirty or forty 
feet high, and yet not spread at the base over four or five feet 
broad. It is easily grown, and as it frequently throws out roots 
from the stem and branches when covered with earth, in trans- 
planting it is well to set it somewhat deeper than where it has 
previously been grown. 
Of the varieties, a new one under the name of Hovey is prob- 
ably the most compact, and of the best color ; but the Siberian 
is a valuable one, growing very compact, and keeping its color 
well in the winter season. Thuja ericoides is of a more delicate 
foliage; sometimes browns badly in the winter, where fully 
exposed to the sun ; while the Tom Thumb, sent out by Messrs,
