The _quince_ thrives best near water; as does the _medlar. Mulberry trees_ are best planted on a lawn, for the convenience of picking up the fruit clean from the grass; as it falls as soon as it is ripe. _Plums_ and _cherries_ require no particular care when grown as standards, except to be sparing in the use of the knife, as both trees, when wounded, are very apt to produce gum; and this, which is an unnatural exudation of the sap, similar to the bleeding of the vines, is very injurious to the trees. The _almond_ is a kind of peach tree, with a leathery fruit instead of a juicy one, the almond being the kernel of the stone. The bitter almond abounds in Prussic acid; but this powerful poison scarcely exists in the kernel of the sweet variety. Almond trees are generally grafted on plum stocks; and they should be grown in a dry soil and a sheltered situation, as the branches are brittle and apt to be broken off by high winds. When almond seeds are sown, the sharp end should be pressed downwards; and the young plants should not be transplanted except when absolutely necessary, as they have very long tap-roots. When the almond is planted for ornament it should have a back-ground of evergreens, as its flowers appear before its leaves. The _walnut_, being a spreading tree with large leaves, should only be planted where no injury will be sustained by a deep shade being cast upon the ground; but it must be observed that its leaves are disliked by all cattle, and are injurious to cows. In pruning it the tips of the branches should be taken off, to make them throw out fruit-bearing shoots. _Sweet chestnuts_ are always propagated by seeds, and never grow well unless the soil contains a portion of sand. The wood is worthless when old. Both walnuts and chestnuts are generally planted in the park. The fruit shrubs grown in gardens may be considered to include the _elder_, the _berberry_, and the _filbert_, though these are frequently called trees. The elder and the berberry will grow anywhere, and require no particular care in their culture; the filbert is only a variety of the common hazel, and both are generally grown on the borders of walks, where they are planted from five to ten feet apart, according as they are to be trained upright or spreading. As the fruit is produced on the young shoots, the bush should be kept open and trained in the cup fashion, in order that the main branches may throw out short young wood. Filberts are propagated by sowing the seeds; and hazel trees by suckers, which they throw up in abundance.
