the brush. It is found that such a coating does not hinder
the juices or sap from expanding in the smallest degree; and the
efficacy of the plan is proved, in preventing the attacks of the
animals, by applying the liquid composition to one tree and missing
another, when it was found that the former was left, while the latter
was attacked. Its efficacy has been shewn by the experience of five
years. The trees that were gone over the first two years have not been
touched since; and none of them have been injured by the hares.--The
Mossing of trees is their becoming much affected and covered with the
moss-plant or mossy substance. It is found to prevail in fruit-grounds
of the apple kind, and in other situations, when they are in low, close,
confined places, where the damp or moisture of the trees is not readily
removed. It is thought to be an indication of weakness in the growth, or
of a diseased state of the trees, and to require nice attention in
preventing or eradicating it. The modes of removing it have usually been
those of scraping, rubbing, and washing, but they are obviously
calculated for trees only on a small scale. How far the use of powdery
matters, such as lime, chalk, and others, which are capable of readily
absorbing and taking up the wetness that may hang about the branches,
and other parts of the trees, by being well dusted over them, may be
beneficial, is not known, but they would seem to promise success by the
taking away the nourishment and support of the moss, when employed at
proper seasons. And they are known to answer in destroying moss in some
other cases, when laid about the stems of the plants, as in
thorn-hedges, &c. The mossing in all sorts of trees is injurious to
their growth by depriving them of a portion of their nourishment, but
more particularly hurtful to those of the fruit-tree kind, as preventing
them from bearing full good crops of fruit by rendering them in a weak
and unhealthy state.----The following are substances destructive of
insects infesting fruit shrubs and trees in gardening, or of preventing
their injurious ravages and effects on trees. Many different kinds of
substances have been recommended for the purpose, at different times;
but nothing perhaps has yet been found fully effectual in this
intention, in all cases. The substances and modes directed below have
lately been advised as useful in this way. As preventives against
gooseberry caterpillars, which so greatly infest a
