ld be sprayed on the trees both early in the
season, while the fruit is small, as well as later.

The cost of this Paris green application, when made on a large scale,
with suitable apparatus, only once or twice a year, must, says Mr.
Forbes, fall below an average of ten cents a tree.

The use of solutions of Paris green or of London purple in water,
applied by spraying machines such as were invented and described in
the reports of the national Department of Agriculture by the U.
S. Entomologist and his assistants, have effected a revolution in
remedies against orchard and forest insects. We expect to see them,
in careful hands, tried with equal success in shrubberies, lawns and
flower gardens.

The Forest.

The White Pine in Europe.

The White Pine was among the very first American trees which came to
Europe, being planted in the year 1705 by Lord Weymouth on his grounds
in Chelsea. From that date, the tree has been cultivated in Europe
under the name of Weymouth Pine; in some mountain districts of
northern Bavaria, where it has become a real forest tree, it is
called Strobe, after the Latin name _Pinus strobus_. After general
cultivation as an ornamental tree in parks this Pine began to be used
in the forests on account of its hardiness and rapid growth, and it
is now not only scattered through most of the forests of Europe, but
covers in Germany alone an area of some 300 acres in a dense, pure
forest. Some of these are groves 120 years old, and they yield a large
proportion of the seed demanded by the increasing cultivation of the
tree in Europe.

The White Pine has proved so valuable as a forest tree that it has
partly overcome the prejudices which every foreign tree has to fight
against. The tree is perfectly hardy, is not injured by long and
severe freezing in winter, nor by untimely frosts in spring or autumn,
which sometimes do great harm to native trees in Europe. On account
of the softness of the leaves and the bark, it is much damaged by the
nibbling of deer, but it heals quickly and throws up a new leader.

The young plant can endure being partly shaded by other trees far
better than any other Pine tree, and even seems to enjoy being closely
surrounded, a quality that makes it valuable for filling up in young
forests where the native trees, on account of their slow growth, could
not be brought up at all.

The White Pine is not so easily broken by heavy snowfall as the
