The potato is undoubtedly the leading addition which the New World has made to the list of garden vegetables. Its importance as a food plant may be judged from the fact that during the year 1880 over one hundred and sixty-nine million bushels of potatoes were raised in the United States. If we could obtain the total yield in all countries for a single year, the figures would express only the simple fact of vastness. It only need be said that potatoes furnish the larger part of the food for many millions of people. Think of Ireland, for example, deprived of her annual crop of potatoes; it means famine and all its attendant ills. The common, or Irish potato, as distinguished from the sweet potato, bears the botanical name of _Solanum Tuberosum_, and belongs to the natural order Solanaceæ. This group or family of plants is characterized by rank scented herbage, often abounding in narcotic poison. The flowers are regular, parts usually in fives, and the ovaries mostly two-celled and many-seeded. Among the more important members of the family are the tomato, egg-plant, cayenne pepper, and tobacco. Belladonna, hyoscyamus, and stramonium are better examples of the poisonous and medicinal properties of the plants in the order, which gives us so wholesome a food as the potato, and so vile a weed as tobacco. The herbage of the potato plant is not unlike that of its first and second cousins, but by means of these narcotic leaves and stems the plant is enabled to transform crude materials into starch and other valuable substances which are afterwards stored up in a suitable form for the use of man. The potato itself, which nearly all persons relish when well prepared for the table, is not a thick root, as many have supposed, but an enlarged underground stem, called a tuber. These thickened subterranean stems bear small leaves, reduced to mere scales, under which are buds, better known as eyes. A potato is as much a stem as the tender and delicious shoots of early spring asparagus. The potato plant has three kinds of stems: those bearing the foliage, those bearing the flowers and the underground stems which may be styled starch-bearing. The early history of the potato is very obscure. It is doubtless a native of South America, where it has been frequently found in the wild state. The Spaniards are given the credit of first introducing the potato into Europe in the early part of the sixteenth century. It passed from Spain into France, and from there on into Germany and other countries of Europe. The first potatoes to reach England were those carried by Sir Walter Raleigh on his return from Virginia in 1584. “In the time of James the First they were so rare as to cost two shillings (sterling) a pound, and are mentioned in 1619 among the articles provided for the royal household.” The culture of the potato was encouraged by the Royal Agricultural Society. Since 1760 it has become an established garden and field crop, and one it would be a calamity to lose.
