In this country the tree is only valuable for its massive aspect and
richly colored thick evergreen leaves, borne on successive tiers of
branches, which render it specially suitable for the decoration of
winter gardens, corridors, and such like situations, where no great
amount of heat is required. In the northern island of New Zealand,
however, it is quite another matter, for there, where it is known as the
Kauri Pine, it furnishes the most valuable of timbers, as may be judged
from the fact that the trunk of the tree attains a height of from 50 to
100 feet clear of the branches; moreover, it yields a gum resin like
copal, which exudes from the trunk, and which is sometimes found below
ground in the vicinity of the trees, thus giving the clew to the real
nature of amber and other similar substances.

The timber is of slow growth, especially valuable for the construction
of masts of ships, its durability, strength, and elasticity rendering it
particularly suitable for this purpose, and Laslett speaks of it as one
of the best woods for working that the carpenter can take in hand, and
recommends its use for the decks of yachts, for cabin panels, for
joiner's work generally, or for ornamental purposes. Owing to the
difficulty and expense of working the forests, and the great distance,
comparatively little of it comes to this country.--_The London
Gardeners' Chronicle_.

HOW TO SUCCESSFULLY TRANSPLANT TREES.
Many think it cheaper and better to take up large trees from the woods,
and transplant them to their grounds or to the road-side, than to buy
nursery trees. As a rule, such trees die; they fail because proper
precautions have not been taken. In digging up a tree, all the roots
outside of a circle a few feet in diameter are cut off, and the tree is
reset with its full head of branches. Whoever has seen trees in the
forest that were upturned by a tornado, must have been struck by the
manner in which the roots run very near to the surface, and to a great
distance. When the roots of these trees are cut off at two or three feet
from the trunk, few or no fibrous or feeding roots are left; and if the
mass of tops is left, the expansion of the buds in the spring will not
be responded to by a supply of sap from the roots, and death must
follow. If such trees have the tops completely removed, leaving only a
bare pole, they will usually grow when transplanted. The tree is little
more than an immense cutting; but there are roots enough left to meet
the demand of the few shoots that start from the top, and growth above
and below ground is well balanced.
