_III. THE FRUIT TREES_

The fruit trees are cultivated for the sake of their fruit. They bear either kernel fruit, when their seed kernels are enclosed in cores of parchment-like formation; or stone fruit, when the seed kernel is enclosed in a hard shell, which is in its turn enclosed in some succulent pulp; or shell fruit, when the fleshy interior is enclosed in a hard shell.

=Almond=, a small tree belonging to the rose family, native to northwest Africa. The flowers are solitary and generally pink, and appear before the lance-shaped leaves. The fruit is egg-shaped, downy externally, with a tough, fibrous covering and a wrinkled stone. It has long been widely cultivated, and many varieties exist, differing in the hardness of the stone and in the flavor of the seed. SWEET ALMONDS include the large thin-shelled Jordan (from the French _jardin_), the Valencia almond, imported as a dessert fruit from Malaga, the smaller Barbary and Italian forms, and the California product. The BITTER ALMOND yields an essential oil, employed in confectionery, but dangerous from sometimes containing prussic acid.

=Apple= (_Pyrus Malus_), grows wild in forests, but it is found artificially improved everywhere in gardens and orchards. Its bark is generally smooth; its wood somewhat soft; its leaves oval-shaped and about double the length of their stalks; its blossoms are white with reddish margins. Fruit horticulture has produced many species of apples in the course of time, and they are now the most important fruit of the temperate zone, area of production, consumption, and variety of product being considered, ranking with the grape, olive, orange, lemon and banana, among the six leading fruits of the world. North America is preëminently the leading apple growing region. In the United States, New York, Pennsylvania, and Ohio produce about one-third of the total crop.

The cultivation of the apple is prehistoric. Abundantly used by Lake Dwellers of the Stone Age in Italy and Switzerland.

=Apricot= (_Prunus Armeniaca_). The tree attains a height of thirteen to sixteen feet, and shows its blossoms in the months of March and April. Its smooth leaves are oval, doubly serrated; and its white blossoms have a tinge of red. Its globular, velvet-like, downy fruits are a favorite dish for dessert.

Apricots are extensively grown in north India, Persia, south Europe and Egypt. Although grown in New York, the crop is only commercially important in California and Oregon, whence large quantities of the fresh and dried fruit are shipped to the eastern states and abroad.

=HOW THE COCOA BEANS ARE DRIED AND ROASTED=

Cultivation in China antedates 2000 B. C. It was introduced into Europe at the time of Alexander the Great, about 325 B. C.

=Bread-fruit= (_Artocarpus incisa_), grows upon the islands of the Pacific Ocean, and has also been transplanted to those parts of America which lie in the Torrid Zone. It attains a very great height, and bears fruits weighing from three to four pounds. The latter are cut into slices, and after being dried and roasted are used as food. These fruits, when pounded and mixed with milk of the cocoanut, form a dough, which is either consumed raw or baked into bread. All parts of this tree are useful; its yellow wood is used for the construction of houses, from its fibres articles of clothing are made, and its sap is used for making birdlime. Its large leaves serve as tablecloths and napkins, and its blossoms when dried are an excellent tinder. The bread-fruit tree is therefore much cultivated.

=Butternut= (_Juglans cinerea_), a North American species of walnut. Its dark yellow wood takes a fine polish, and is used in cabinet work; the bark yields a brown dye, and the brown-husked, rugged nuts contain oil, and are very pleasant in flavor.
