Chapter I: Esculent Roots (2)

_Use._--The flesh is remarkably white, and very mucilaginous in its crude state. The roots are eaten either boiled or roasted, and require rather more than half the time for cooking that is usually given to the boiling or roasting of the common potato. When cooked, they possess a rice-like taste and consistency, are quite farinaceous, and unquestionably nutritive and valuable for food.

CHUFA, OR EARTH ALMOND.

EDIBLE CYPERUS. NUT RUSH.

Cyperus esculentus.

A perennial plant, from the south of Europe. The roots are long and fibrous, and produce at their extremities numerous small, rounded or oblong, jointed, pale-brown tubers, of the size of a filbert. The flesh of these roots, or tubers, is of a yellowish color, tender, and of a pleasant, sweet, and nut-like flavor. The leaves are rush-like, about eighteen inches high, a little rough, and sharply pointed. The flower-stalks are nearly of the same height as the leaves, three-cornered, hard, and leafless, with the exception of five or six leaflike bracts at the top, from the midst of which are produced the spikelets of flowers, which are of a pale-yellow color.

_Propagation and Culture._--It is propagated by planting the tubers in April or May, two inches deep, in drills two feet apart, and six inches apart in the drills. They will be ready for harvesting in October. In warm climates, the plant, when once introduced into the garden, spreads with great rapidity, and is exterminated with much difficulty. In the Northern and Middle States, the tubers remaining in the open ground are almost invariably destroyed by the winter.

_Use._--It is cultivated for its small, almond-like tubers, which, when dried, have somewhat the taste of the almond, and keep a long period. They are eaten either raw or roasted.

"The plant grows spontaneously in the light, humid soils of Spain; and is cultivated in Germany and the south of France. The tubers are chiefly employed for making an orgeat,--a species of drink much used in Spain, Cuba, and other hot climates where it is known. When mashed to a flour,--which is white, sweet, and very agreeable to the taste,--it imparts to water the color and richness of milk."--_Hort._

GERMAN RAMPION.

TREE PRIMROSE. EVENING PRIMROSE.

OEnothera biennis.

The German Rampion, or Evening Primrose, common in this country to gravelly pastures and roadsides, is a hardy biennial plant, and, when in full perfection, measures three or four feet in height, with long, flat, pointed leaves, and large, yellow, fragrant flowers. The seed-pods are oblong, four-sided; the seeds are small, angular, of a brown color, and retain their germinative properties three years.

_Sowing and Cultivation._--The seeds should be sown annually, in April, in a rich and shady situation; for if grown in a dry, sunny exposure, and sown very early in the season, the plants are inclined to run to flower during the summer: which renders the roots worthless; for they then become hard and fibrous. Sow in drills an inch deep, and fourteen inches apart; thin to six or eight inches in the rows; cultivate in the usual form; and, in September, the roots will be ready for use. For winter use, take up the roots before freezing weather, and pack in sand. For spring use, they may be taken directly from the ground.

_To raise Seed._--Two or three plants, left in the ground through the winter, will yield an abundant supply of seeds the following summer.

_Use._--The root is the only part used. This, when full grown, is generally from ten to twelve inches long, fusiform, occasionally with a few strong fibres, whitish on the outside, and white within. The thick, outer covering separates readily, and should be removed when the root is eaten in its crude state. It possesses a nutty flavor; but is inferior to the true Rampion, having a slight pungency. If required as a raw salad, it should be eaten while young. When the roots have attained their full size, they are usually dressed in the manner of Skirret and Scorzonera.

JERUSALEM ARTICHOKE.

Helianthus tuberosus.

The Jerusalem Artichoke is a hardy perennial. In its manner of growth and flowering, it much resembles the common sunflower; of which, as its scientific term suggests, it is really a species. Stem six to eight feet high, very rough, and much branched; leaves alternate, large, rough, heart-shaped at the base, pointed at the ends, and indented on the borders; flowers large, yellow,--produced on the top of the plant, at the extremities of the branches.

_Soil, Propagation, and Culture._--"It thrives best in a light, mellow soil, made rich by the application of old, decomposed manure; but the roots will flourish well if planted in any corner of the garden less suited for other descriptions of vegetables. To obtain fine roots, however, the soil should be trenched fifteen or eighteen inches in depth.

"It is propagated by planting the small tubers, or offsets: the large tubers may also be cut or divided into several pieces, each having one eye, as practised with the potato. In April, or early in May, lay out the rows three feet apart, drop the tubers one foot apart in the rows, and cover three inches deep. As the plants come up, hoe the ground between the rows from time to time; and draw a little earth around their stems, to support them, and to afford the roots a thicker covering."

_Taking the Crop._--The new tubers will be suitable for use in the autumn. In digging, great care should be taken to remove the small as well as the full-grown; for those not taken from the ground will remain fresh and sound during the winter, and send up in the spring new plants, which, in turn, will increase so rapidly, as to encumber the ground, and become troublesome. In localities where the crop has once been cultivated, though no plants be allowed to grow for the production of fresh tubers, yet the young shoots will continue to make their appearance from time to time for many years.

_Use._--"The roots, or tubers, are the parts of the plant eaten. These are boiled in water till they become tender; when, after being peeled, and stewed with butter and a little wine, they will be as pleasant as the real Artichoke, which they nearly resemble both in taste and flavor."

M'Intosh says that the tubers may be used in every way as the potato; and are suited to persons in delicate health, when debarred from the use of most other vegetables.

_Varieties._--For a long period, there was but a single variety cultivated, or even known. Recent experiments in the use of seeds as a means of propagation have developed new kinds, varying greatly in their size, form, and color, possessing little of the watery and insipid character of the heretofore grown Jerusalem Artichoke, and nearly or quite equalling the potato in flavor and excellence.

COMMON WHITE.

Tubers large, and often irregular in form; skin and flesh white; quality watery, and somewhat insipid. It is unfit for boiling, but is sometimes served baked or roasted. It makes a very crisp and well-flavored pickle.

PURPLE-SKINNED.

A French variety, produced from seed. Tubers purplish rose-color; flesh dryer when cooked, and finer flavored, than that of the foregoing.

RED-SKINNED.

Like the Purple-skinned, produced from seed. Skin red. Between this and the last named there are various intermediate sorts, differing in shades of color, as well as in size, form, and quality.

YELLOW-SKINNED. _Law._

The tubers of this variety are of a yellowish color, and are generally smaller, and even more irregularly shaped, than those of the Common White. They are, however, superior in quality, and of a more agreeable taste when cooked.

KOHL RABI.

TURNIP CABBAGE.

Brassica caulo-rapa.

The Kohl Rabi is a vegetable intermediate between the cabbage and the turnip. The stem, just above the surface of the ground, swells into a round, fleshy bulb, in form not unlike a turnip. On the top and about the surface of this bulb are put forth its leaves, which are similar to those of the Swede turnips; being either lobed or entire on the borders, according to the variety. The seeds are produced the second year; after the ripening of which, the bulb perishes.

_Sowing and Cultivation._--Mr. Thompson's directions are as follows: "Kohl Rabi may be sown thinly, broadcast, or in drills four inches apart, in April, May, or June. When the young plants are an inch or two in height, they may be transplanted into any good, well-enriched piece of ground, planting them eight inches apart, in rows fifteen inches asunder, and not deeper in the ground than they were in the seed-bed. Water should be given till they take fresh root, and subsequently in dry weather as required; for though the plants suffer little from droughts, yet the tenderness of the produce is greatly impaired by an insufficient supply of moisture. With the exception of stirring the ground and weeding, no further culture is required. The crop will be fit for use when the bulbs are of the size of an early Dutch turnip: when allowed to grow much larger, they are only fit for cattle. Of field varieties, the bulbs sometimes attain an immense size; weighing, in some cases, fourteen pounds."

_Seed._--Take up a few plants entire in autumn; preserve them during winter in the manner of cabbages or turnips; and transplant to the open ground in April, two feet apart in each direction. The seeds are not distinguishable from those of the Swede or Ruta-baga Turnip, and retain their vitality from five to seven years.

_Use._--The part chiefly used is the turnip-looking bulb, formed by the swelling of the stem. This is dressed and eaten with sauce or with meat, as turnips usually are. While young, the flesh is tender and delicate, possessing the combined flavor of the cabbage and turnip.

They are said to keep better than any other bulb, and to be sweeter and more nutritious than the cabbage or white turnip. "In the north of France, they are extensively grown for feeding cattle,--a purpose for which they seem admirably adapted, as, from having a taste similar to the leaves of others of the species, they are found not to impart any of that peculiar, disagreeable taste to the milk, which it acquires when cows are fed on turnips."

_Varieties._--These are as follow:--

ARTICHOKE-LEAVED. _Thomp._ _Vil._

Cut-leaved.

Of German origin, deriving its name from the resemblance of the leaves to those of the Artichoke. Bulb small, and not smooth or symmetrical. The leaves are beautifully cut, and are very ornamental; but the bulb is comparatively of little value. Not much cultivated.

EARLY DWARF WHITE. _Vil._

Bulb white, smaller than that of the Common White, and supported close to the ground. The leaves are also smaller, and less numerous.

It is earlier, and finer in texture, than the last named; and, while young, excellent for the table.

Transplant in rows fifteen inches apart, and ten inches asunder in the rows.

EARLY PURPLE VIENNA. _Thomp._ _Vil._

This corresponds with the Early White Vienna, except in color, which, in this variety, is a beautiful purple, with a fine glaucous bloom. The leaf-stems are very slender, and the leaves smooth, and few in number.

These two Vienna sorts are by far the best for table use. When taken young, and properly dressed, they form an excellent substitute for turnips, especially in dry seasons, when a crop of the latter may fail or become of inferior quality.

EARLY WHITE VIENNA. _Thomp._

Dwarf, small, early; bulb handsome, firm, glossy, white, or very pale-green. The leaves are few, small, with slender stems, the bases of which are dilated, and thin where they spring from different parts on the surface of the bulb. The flesh is white, tender, and succulent, whilst the bulb is young, or till it attains the size of an early white Dutch turnip; and at or under this size it should be used.

Set the plants in rows fifteen inches apart, and ten inches from plant to plant in the lines.

GREEN.

Similar to, if not identical with, the Common White. The bulbs are pale-green, attain a very large size, and the variety is hardy and productive. Not suited to garden culture, but chiefly grown for farm-purposes.

PURPLE. _Thomp._ _Vil._

This variety differs little from the White, except in color; the bulb being purple, and the leaf-stems and nerves also tinged with purple. Like the White, it attains a large size, and is only adapted for field culture; the flesh being too coarse and strong-flavored for table use.

WHITE. _Thomp._ _Vil._

Bulb large,--when full grown, measuring seven or eight inches in diameter, and weighing from eight to ten pounds; leaves rather large and numerous; skin very pale, or whitish-green; stem about six inches high. Hardy, very late, and chiefly employed for farm-purposes.

The variety should be cultivated in rows eighteen inches apart, and the plants should stand one foot apart in the rows.

* * * * *

OXALIS, TUBEROUS-ROOTED.--_Law._

Tuberous-rooted Wood-sorrel. Oca. Oxalis crenata.

Of the Tuberous-rooted Oxalis, there are two varieties, as follow:--

WHITE-ROOTED.

Oca blanca.

Stem two feet in length, branching, prostrate or trailing, the ends of the shoots erect; leaves trifoliate, yellowish-green, the leaflets inversely heart-shaped; flowers rather large, yellow,--the petals crenate or notched on the borders, and striped at their base with purple. The seeds are matured only in long and very favorable seasons. In its native state, the plant is perennial; but is cultivated and treated, like the common potato, as an annual.

_Cultivation._--The tubers should be started in a hot-bed in March, and transplanted to the open ground in May, or as soon as the occurrence of settled warm weather. They thrive best in dry, light, and medium fertile soils, in warm situations; and should be planted in hills two feet and a half apart, or in drills two feet and a half apart, setting the plants or tubers an inch and a half deep, and fifteen or eighteen inches apart in the drills; treating, in all respects, as potatoes.

The tubers form late in the season; are white, roundish, or oblong, pointed at the union with the plant, and vary in size according to soil, locality, and season; seldom, however, exceeding an inch in diameter, or weighing above four ounces. The yield is comparatively small.

_Use._--The tubers are used as potatoes. When cooked, the flesh is yellow, very dry and mealy, of the flavor of the potato, with a very slight acidity. The tender, succulent stalks and foliage are used as salad.

OXALIS, RED TUBEROUS-ROOTED.

Oca colorada.

Plant similar in habit to the White Tuberous-rooted; but the branches, as well as the under surface of the leaves, are more or less stained with red. Tubers larger than those of the last named, roundish, tapering towards the connection with the plant, and furnished with numerous eyes in the manner of the common potato; skin smooth, purplish-red; flesh often three-colored,--the outer portion of the tuber carmine-red, the central part marbled, and the intermediate portion yellow,--the colors, when the root is divided transversely, appearing in concentric zones, or rings. The flesh contains but little farinaceous matter, and possesses a certain degree of acidity, which, to many palates, is not agreeable.

Propagated, and in all respects cultivated, like the White. Either of the varieties may also be grown from cuttings, which root readily.

According to a statement from the London Horticultural Society's Journal, the acidity may be converted into a sugary flavor by exposing the tubers to the action of the sun for eight or ten days,--a phenomenon which is analogous to what takes place in the ripening of most fruits. When treated in this form, the tubers lose all trace of acidity, and become as floury as the best descriptions of potatoes. If the action of the sun is continued for a long period, the tubers become of the consistence and sweet taste of figs. Mr. Thompson states that the disagreeable acid taste may also be removed by changing the water when they are three-quarters boiled.

The plants are tender, and are generally destroyed early in autumn by frost. The tubers must be taken up before freezing weather, packed in sand, and placed in a dry, warm cellar for the winter.

DEPPE'S OXALIS. _Thomp._ _Vil._

Oxalis Deppei.

A perennial plant from Mexico, very distinct from the tuberous-rooted species before described. Stalk about one foot in height, smooth and branching; leaves four together, the leaflets wedge-shaped, pale yellowish-green, the upper surface marked by two brownish lines or stains in the form of two sides of a triangle; flowers terminal, of a carmine-rose or pink-red color, stained with green at the base of the petals. "The roots are fleshy, tapering, white, and semi-transparent, and furnished on the top of the crown with a mass of scaly bulbs, sometimes amounting to fifty in number, by means of which the plant can be easily propagated. When well grown, the roots are about four inches in length, and from one inch to one inch and a half in thickness."--_Thomp._

_Soil and Culture._--"This Oxalis requires a light, rich soil, mixed with decayed vegetable matter; and it prefers a southern aspect, provided the soil is not too dry.

"It may be raised from seed; but is generally propagated by planting the bulbs, which should be set the last of April or beginning of May, or when all danger of frost is over, six inches apart, in rows one foot asunder. The bulbs should be only just covered with soil; for thus they occupy a position, with regard to the surface, similar to that in which they are produced: and this seems indispensable, if fine roots are to be obtained.

"The stems have been observed to spring up from a considerable depth; but, in this case, tap-roots were not formed. During summer, the soil must be kept moist in dry weather; otherwise, when rain falls abundantly, the sudden accession of water to the roots occasions their splitting. The plants should be allowed to grow as long as there is no danger from frost; but, previous to this occurring, they should either be taken up or protected. If protected from frost by frames or otherwise, the roots will continue to increase in size till near November. When taken up, the roots should be divested of the numerous bulbs formed on their crowns, and then stored up for use in a cool, dry place, but secure from frost. A similar situation will be proper for the small bulbs; or they may be kept in dry sand till the season of planting."--_Thomp._

The plant has been cultivated with the most complete success, with no especial preparation of the soil; merely planting the bulbs in shallow drills, the ground being dug and manured as for other kitchen-garden crops.

_Use._--In a communication to the "Gardener's Chronicle," Prof. Morren gives the uses of the plant as follow:--

"The uses of the Oxalis are many. The young leaves are dressed like sorrel in soup, or as a vegetable. They have a fresh and agreeable acid, especially in spring. The flowers are excellent in salad, alone, or mixed with corn salad, endive of both kinds, red cabbage, beet-root, and even with the petals of the dahlia, which are delicious when thus employed. When served at table, the flowers, with their pink corolla, green calyx, yellow stripes, and small stamens, produce a fine effect. The roots are gently boiled with salt and water, after having been washed and slightly peeled. They are then eaten like asparagus in the Flemish fashion, with melted butter and the yolk of eggs. They are also served up like scorzonera and endive, with white sauce; and form, in whatever way they are dressed, a tender, succulent dish, easy to digest, agreeing with the most delicate stomach. The analogy of the root with salep indicates that its effect should be excellent on all constitutions."

"The bright rose-colored flowers being very ornamental, the plant is sometimes employed as an edging for walks."--_Thomp._

* * * * *

THE PARSNIP.

Pastinaca sativa.

The Parsnip is a hardy biennial, indigenous to Great Britain and some parts of the south of Europe, and, to a considerable extent, naturalized in this country. In its native state, the root is small and fibrous, and possesses little of the fineness of texture, and delicacy of flavor, which characterize the Parsnip in its cultivated state.

The roots are fusiform, often much elongated, sometimes turbinate, and attain their full size during the first year. The flowers and seeds are produced the second year; the plant then measuring five or six feet in height, with a grooved or furrowed, hollow, branching stem. The flowers are yellow, in large spreading umbels five or six inches in diameter. The seeds ripen in July and August; are nearly circular; about one-fourth of an inch in diameter; flat, thin, very light, membranous on the borders, and of a pale yellowish-brown or yellowish-green color. They vary but little in size, form, or color, in the different varieties; and retain their vitality but two years. About six thousand seeds are contained in one ounce.

_Propagation, Soil, and Cultivation._--It is always propagated from seed sown annually.

_Soil._--The soil should be mellow, deep, and of a rich vegetable texture. "If in moderate condition by the manuring of the previous crop, it will be better than applying manure at sowing. Should it be necessary to do so, let the manure be in the most thorough state of decomposition; or, if otherwise, incorporate it with the soil, as far from the surface as possible. The Parsnip will grow in a stronger soil than the Carrot; and succeeds comparatively well when grown in sand, or even in peat, if well manured."

_Preparation of the Ground, and Sowing._--"The seed should be sown as early in spring as the ground is in good working condition. As most of the varieties have long fusiform roots, ordinary ploughing will not stir the soil to a sufficient depth for their greatest perfection; and, as the amount of the crop mainly depends on the length of the roots, it is of the first importance to provide for this fact by making the ground fine and friable above and below, to the depth of at least fifteen inches: eighteen or twenty would be better. When the soil has thus been thoroughly pulverized, level off the surface, and rake it fine and smooth, and sow the seed in drills fourteen inches apart and an inch and a half deep; allowing half an ounce of seed for one hundred feet of drill, and from five to six pounds to the acre. When the young plants are two or three inches high, thin them out to about six inches in the rows; and, as they transplant readily, any vacant space can be filled by resetting the surplus plants. Keep the earth between the rows loose, and free from weeds, and also the spaces in the rows, until the leaves cover the ground; after which, little further care will be required. The roots will attain a good size by the middle of September, from which time a few may be drawn for present use; but the Parsnip is far best at full maturity, which is indicated by the decay of the leaf in October."

_Harvesting._--The Parsnip sustains no injury when left in the open ground during winter; and it is a common practice to take up in the fall a certain quantity of roots to meet a limited demand in the winter months, allowing the rest to remain in the ground until spring. The roots thus treated are considered to have a finer flavor; that is to say, are better when recently taken from the ground.

In taking up the crop in autumn, which should be done just previous to the closing-up of the ground, be careful to remove the soil to a sufficient depth, so as not to injure the roots. The thrust of the spade that easily lifts a Carrot without essential injury, will, if applied to the Parsnip, break the roots of nine in ten at scarcely half their length from the surface of the ground. As the roots keep much fresher, and retain their flavor much better, when taken up entire, the best method is to throw out a trench beside the rows, to the depth of the roots, when they can be easily, as well as perfectly, removed. They should be dug in pleasant weather, and laid on the ground exposed to the sun for a few hours to dry; "and when all the earth is rubbed off them, and their leaves cut off to within an inch of their crowns, they may be stowed away in sand, dry earth, or in any dry, light material most convenient." When thus packed, they will keep well in almost any location, either in the cellar or storehouse.

If the roots which have remained in the ground during winter be taken up in spring, and the tops removed as before directed, they may be packed in sand or earth, and will remain fresh and in good condition for use until May or June.

_To raise Seed._--In April, thin out the roots, that have been in the ground during the winter, to about eighteen inches apart; or, at the same season, select a few good-sized and symmetrical roots from those harvested in the fall, and set them eighteen inches apart, with the crowns just below the surface of the ground. They will send up a stalk to the height and in the manner before described, and the seeds will ripen in August. The central umbel of seeds is always the largest, and is considered much the best.

_Use._--"The Parsnip is considered as a wholesome and nutritious article of food, and is served at table in various styles in connection with salted meats and fish. The roots, aside from this manner of using, form what may be called an excellent side-dish; when, after being boiled, not too soft, they are dipped in thin batter of flour and butter or the white of eggs, and afterwards fried brown."

They contain a considerable portion of sugar, and are considered more nutritive than carrots or turnips. The roots form a common ingredient in soups; and are sometimes used for making bread, and also a kind of wine said to resemble Malmsey of Madeira.

Aside from the value of the Parsnip as a table vegetable, it is one of the most economical roots for cultivation for farm purposes, as it not only produces an abundant and almost certain crop, but furnishes very nourishing food particularly adapted to and relished by dairy-stock.

_Varieties._--The varieties, which are not numerous, are as follow:--

COMMON, OR DUTCH. _Trans._

Swelling Parsnip. Long Smooth Dutch.

The leaves of this kind are strong and numerous; generally about two feet long or high. The roots are from twenty to thirty inches in length, and from three to four inches in diameter at the shoulder, regularly tapering to the end, occasionally producing a few strong fangs. The crown is short and narrow, elevated, and contracting gradually from the shoulder, which is generally below the surface of the ground.

Seeds from America, Holland, and Germany, sown in the garden of the London Horticultural Society, all proved alike; though some were superior to others in the size of their roots, owing, it was thought, both to a careful selection of seed-roots and to the age of the seeds. It was found that new seeds uniformly produced the largest roots.

EARLY SHORT-HORN. _M'Int._

A recently introduced variety, similar to the Turnip-rooted, but shorter. Very delicate and fine-flavored.

GUERNSEY. _Trans._

Panais Long, of the French.

The leaves of this kind grow much stronger and somewhat taller than those of the Common Parsnip. The leaflets are also broader. The only distinguishable difference in the roots is, that those of the Guernsey Parsnip are the larger and more perfect, being sometimes three feet long. Roots produced from seed obtained from Guernsey were evidently much superior to those which were grown from seed raised in other localities: from which it would appear that the Guernsey Parsnip is only an improved variety of the Common, arising from soil and cultivation in that island. Dr. M'Culloch states that, in Guernsey, its roots grow to the length of four feet. In its flavor, it differs little from the Common Dutch Parsnip.

HOLLOW-CROWNED. _Trans._

Long Jersey. Hollow-crowned Guernsey. Hollow-headed.

In this variety, the leaves are shorter and not so numerous as those of the Common Parsnip. The roots are oblong, about eighteen inches in length, and four inches in diameter at the shoulder, more swollen at the top, and not tapering gradually, but ending somewhat abruptly with a small tap-root. The crown is short, and quite sunk into the shoulder, so as to form a hollow ring around the insertion of the stalks of the leaves; and grows mostly below the surface of the ground.

It is a good sort for general cultivation, especially as it does not require so deep a soil as either the Common, or Guernsey. There is little difference in the flavor or general qualities of the three varieties.

SIAM, OR YELLOW. _Thomp._

Panais de Siam.

This is said to be more tender and richer in flavor than any of the other varieties. It is mentioned by Dr. Neill in the "Encyclopædia Britannica," and is described by M. Noisette as being yellowish in color, and in form intermediate between the Guernsey and Turnip-rooted Parsnips. He also states that it is the most esteemed. It does not, however, appear to be known at the present day in this country.

TURNIP-ROOTED. _Trans._

Panais Rond, of the French.

The leaves of this sort are few, and do not exceed twelve to sixteen inches in length. The roots are from four to six inches in diameter, tunnel-shaped, tapering very abruptly, with a strong tap-root; the whole being from twelve to fifteen inches in length. The rind is rougher than either of the other sorts; the shoulder very broad, growing above the surface of the soil; convex, with a small, short crown. It is much the earliest of the parsnips; and, if left in the ground, is liable to rot in the crown. The leaves also decay much sooner than those of most other sorts.

It is particularly adapted to hard and shallow soils; and, from its coming into use much earlier than any other kind, very desirable. In flavor, it is mild and pleasant, though less sugary than the long-rooted kinds. The flesh, when dressed, is more yellow than that of any other variety.

THE POTATO.

Solanum tuberosum.

The Potato is a native of Central or Tropical America. In its wild or natural state, as found growing on the mountains of Mexico or South America, the tubers rarely exceed an inch in diameter, and are comparatively unpalatable. During the last half-century, its cultivation within the United States has greatly increased; and it is now considered the most important of all esculent roots, and next to the cereals in value as an article of human subsistence.

_Soil._--The soils best suited to the Potato are of the dryer and lighter descriptions; pasture lands, or new land, with the turf freshly turned, producing the most abundant as well as the most certain crops. On land of a stiff, clayey texture, or in wet soils, they are not only extremely liable to disease, but the quality is usually very inferior. "On soils which have been long cropped and heavily manured, they rarely succeed well; and hence garden ground, in most cases, does not produce tubers of so good quality as those obtained from the fields."

_Fertilizers._--"In good garden soil, the less manure that is used, the better flavored will be the produce; and it will also be much less affected by the disease. Therefore, whilst the malady prevails, or symptoms of it still remain, it is not advisable to apply much manure.

"Amongst the fertilizers that are employed, may be enumerated, in addition to barnyard and stable manure, leaves, leaf-mould, peat-charcoal, and other carbonaceous substances, lime, gypsum, or plaster, and bone-dust.

"Wood-ashes are useful in supplying potash and other inorganic substances required by the plant; and they may be advantageously applied where the soil contains a large amount of decayed vegetable matter. The same remark will also apply to lime, which is useful in destroying slugs and other vermin, which attack the tubers. Plaster, bone-dust, and superphosphate of lime, are best for humid soils. They induce earliness; and where this is an object, as it must be so long as the disease continues, they may be applied with considerable advantage."--_Thomp._

_Propagation._--"This is almost universally from tubers; the seed being seldom sown, except for the production of new varieties. With many it is a doubtful question, whether the tubers cut, or planted whole, yield the greater return. From experiments made in the garden of the London Horticultural Society at Chiswick, it was found, on the mean of two plantations,--one made early in the season, and the other about one month later,--that the produce from cut sets exceeded that from whole tubers by nearly one ton per acre. In the latter planting, the produce from whole tubers was somewhat greater than that from single eyes: but, in the early plantation, the cut sets gave nearly two tons per acre more produce than the whole tubers; the weight of potatoes planted being deducted in every case.

"Another important consideration is, whether small tubers or large ones should be employed for making sets; for if, by using the former, an equally good crop could be obtained, a considerable saving in the expense of sets would be effected. Large tubers, however, are preferable, for the following reasons: In all plants, large buds tend to produce large shoots; and small or weak buds, the reverse. Now, the eyes of potatoes are true buds, and in small tubers they are comparatively weak: they consequently produce weak shoots, and the crop from such is inferior to that obtained from plants originating from larger tubers, furnished with stronger eyes; and this conclusion has been justified by the results of actual experiments.

"The part of the Potato employed for planting is not a matter of indifference. It was found, by an experiment made in the garden of the Horticultural Society, that sets taken from the points of the tubers, and planted early in the season, yielded at the rate of upwards of three tons per acre more produce than was obtained from employing the opposite end of the tubers. In a plantation made a month afterwards, the difference was much less, but still in favor of the point, or top end, of the Potato."--_Thomp._

With regard to the quantity of seed per acre, great diversity of opinion exists among cultivators. Much, of course, depends on the variety, as some sorts not only have more numerous eyes, but more luxuriant and stronger plants, than others. Of such varieties, a much less quantity will be required than of those of an opposite character. From a series of experiments carefully made for the purpose of ascertaining the amount of seed most profitable for an acre, it was found that from six to eight bushels, if planted in hills, answered better than more: for, when too much seed was used, there were many small tubers; and where the tubers had been divided into very small parts, or single eyes, the plants were more feeble, and the yield less in number and weight, though usually of larger size.

_Methods of Planting and Cultivation._--Potatoes are usually planted either in hills or ridges; the former method being the more common in this country. If planted in hills, they should be made from three feet to three and a half apart; the distance to be regulated by the habit of the variety under cultivation. If in ridges or drills, they may be made from two and a half to three feet apart; although some of the earlier and smaller kinds may be successfully grown at eighteen or twenty inches.

"Of sets formed by the division of an average-sized tuber into four parts, three may be allowed a hill; or, if planted in drills, the sets may be placed from seven to twelve inches asunder,--the distance to be regulated by the habit or size of the plant. On light, warm land, the sets should be covered about four inches in depth; but in wet, cold soil, three inches will be sufficient.

"As soon as the plants are fairly above the surface, hoeing and surface-stirring should be commenced. The earth should gradually be drawn about the hills, or along the ridges, at each successive hoeing, and every encouragement given to the side-roots to extend themselves: for nearly at their extremities the tubers are formed; so that deeply stirring the ground between the hills or ridges tends to their extension. This latter treatment, however, must not be carried beyond a certain stage in the growth of the plant, or after the tubers have reached a considerable size, as the extremities of the roots might be seriously injured. Some varieties of potatoes produce their tubers at a much greater distance from the stem than others. These are chiefly to be found among the later sorts. Most of the early kinds produce theirs close to the stem, or at the extremity of very short runners; seldom more than nine inches from the stalk of the plant."

_Forcing._--This should be commenced from three to four weeks before the season for planting in the open ground. The earliest varieties should be chosen for the purpose, selecting whole tubers of medium size, and placing them close together, in a single layer, among half-decayed leaves or very light loam, on the surface of a moderate hot-bed.

"When the shoots have attained the height of two or three inches, and the weather has become sufficiently mild, they should be carefully taken out, and divided into sets; in the process of cutting up the tubers, avoiding as much as possible doing injury to the small fibrous roots, and also to the growing shoots. These sets should then be planted out in hills or drills, in the usual manner and at the usual depth; if possible, leaving the upper portion of the young shoot just above the surface of the ground. Some care is requisite in planting out the sets, particularly in covering; for, if the soil is applied too rudely, the sprouts, which separate very easily from the tubers, are exceedingly liable to be broken off, and the set destroyed for early use. If severe cold or frosty weather occurs, the plants should be protected by straw, or any convenient, light material, placed along the drills or on the hills."

_Taking the Crop, and Method of Preservation._--"The early varieties should be dug for use as they attain a suitable size; which, in warm exposure, will be about the beginning of July; and thence till the middle of August, in less favorable places. The practice of partially removing the soil from about the roots, and gathering the largest tubers, leaving the smaller ones, with the expectation that they will attain a larger size, is a mode of proceeding which seldom realizes the hopes of the cultivator; for the Potato, if once disturbed at the roots, seldom recovers the check.

"When no apprehension is felt on account of disease, a week's delay in commencing on the crop will be found of great importance both to the bulk and quality; for just previous to the decay of the tops, if pleasant weather prevails and the ground is sufficiently moist, the tubers increase in size with great rapidity.

"Late varieties usually constitute the great portion of the main crop, and are those which require most care in taking up and storing. So long as the plants continue green, the Potato should be allowed to remain in the ground; as this is quite indicative that the tubers have not arrived at full maturity."

In the preservation of potatoes, it is of the first importance that they be excluded from light. If this is neglected, they become not only injurious, but actually poisonous; and this is especially the fact when they are allowed to become of a green color, which they readily will do on exposure to the light. In a state of complete darkness they should therefore be placed, the day they are taken out of the ground; and it were even better that they were stored in rather a damp state, than that they should be exposed for a day to the light with a view to dry them. Drying has a bad effect on the skin of the Potato; for, if subjected to this, the skin and part of the epidermis are made to part with their natural juices, which ever afterwards renders them incapable of absorbing moisture, even if presented to them. Fermentation is also an important evil to be guarded against, as it changes the whole substance of the Potato, and, so far as seed potatoes are concerned, destroys their vegetative principle. As security against this, they should be stored either in barrels or boxes, or in long, narrow ridges, with partitions of earth between. Potatoes once dried should never be again moistened until just before using.

"Keeping potatoes has the effect of diminishing the quantity of starch contained in them. According to Mr. Johnson, those which in October yielded readily seventeen per cent of starch, gave, in the following April, only fourteen and a half per cent. The effect of frost is also to lessen the quantity of starch. It acts chiefly upon the vascular and albuminous part; but it also converts a portion of the starch into sugar: hence the sweetish taste of frosted potatoes."--_M'Int._

_Varieties._--Messrs. Peter Lawson and Sons describe one hundred and seventy-five varieties: and other foreign authors enumerate upwards of five hundred, describing the habit of the plant; size, form, and color of the tubers; quality and general excellence; and comparative value for cultivation.

They are obtained from seeds; the latter being quite small, flat, and lens-shaped. One hundred and five thousand are contained in an ounce, and they retain their germinative properties three years.

The process is as follows: "Select some of the largest and best berries, or balls, when fully ripe, which is denoted by the withering of the stalk; and separate the seeds from the pulp, and dry them thoroughly in the sun. These should be sown in the following spring, and the produce taken up in October. The tubers will then have nearly attained the size of small plums. The best of these should be selected, and the product of each plant carefully and separately preserved. In the month of April following, they should be planted at a distance from one another of from fifteen to eighteen inches; and, when they rise about two inches from the ground, they should be earthed up slightly with the hoe,--an operation which may be repeated during the season. When they have arrived at maturity, they are to be taken up, keeping the product of each stalk by itself; which product is again to be planted the ensuing spring. A judgment of the properties of the varieties will then have been formed, and those are to be reserved for cultivation which are approved of. It will be found, that, whatever had been the character of the parent stock, the seeds will produce numerous varieties, some white, some dark, in color, with tubers of different forms, round, oblong, and kidney-shaped, and varying greatly in the dryness, color, and farinaceous character, of the flesh."--_Low._

ASH-LEAVED EARLY.

Stem nearly two feet in height, erect, with long, smooth, shining, and drooping foliage; flowers very seldom produced; tubers white, roundish, rough-skinned; flesh white, of medium quality. The variety is healthy, and remarkably early; well suited to open culture, but not adapted for growing under glass, on account of its tall habit.

ASH-LEAVED KIDNEY.

One of the earliest of the garden varieties, well adapted for forcing under glass or for starting in a hot-bed, and subsequent cultivation in the open ground. The plant is of spreading habit, and about eighteen inches in height; leaves small, recurved; tubers of medium size, kidney-shaped, white; flesh white, dry, and well flavored. Very healthy. Introduced.

BISCUIT. _Law._

Plant two feet and a half high, spreading; leaves rather rough, large, and of a pale-green color; flowers whitish; tubers rather small, round, smooth, and of a light-brownish color. A very healthy variety, mealy, well flavored, and quite productive. The plants do not decay, nor do the tubers attain full maturity, until nearly the close of the season: the latter are, however, of good quality, and in perfection for the table soon after being harvested.

BLACK CHENANGO.

Black Mercer.

Plant vigorous, and generally of healthy habit; tubers nearly of the form of the Lady's Finger, but of larger size; skin very deep purple, or nearly black; flesh purple, both in its crude state and when cooked; quality good, usually dry, and of good flavor.

The Black Chenango is moderately productive, and withstands disease better than almost any other potato; but its dark color is objectionable. Compared with many of the recent varieties, it has little merit, and is not a profitable sort for extensive cultivation.

BUCKEYE.

A Western variety; grown also to a considerable extent in some parts of the Middle States. "It is a handsome, round potato; white throughout, except a little bright pink at the bottom of the eye. It is very early,--ripening as early as the Chenango; attains a good marketable size as soon as the Dykeman; cooks very dry and light; and is fine flavored, particularly when first matured. It throws up a very thick, vigorous, and luxuriant vine; grows compactly in the hill, and to a large size, yielding abundantly."

For planting for early use, it is a promising variety: but for a late or medium crop, upon strong, rich ground, it is said to grow so rapidly, and to so great a size, that many of the tubers are liable to be hollow-hearted; which considerably impairs their value for table use.

CALICO.

Similar to the Pink-eyed; varying little except in color, which is mostly red, with occasional spots and splashes of white. It is in no respect superior to the last-named variety in quality, and cannot be considered of much value for agricultural purposes or for the table.

CALIFORNIA RED.

A bright-red potato from California. Tubers variable in form, from long to nearly round, rather smooth; eyes slightly depressed.

It is one of the most productive of all the varieties; but, on account of its extreme liability to disease, cannot be recommended for general cultivation.

CARTER.

A medium-sized, roundish, flattened, white potato, once esteemed the finest of all varieties, but at present nearly or quite superseded by the Jackson White, of which it is supposed to be the parent. Eyes rather numerous, and deeply sunk; flesh very white, remarkably dry, farinaceous, and well flavored. Originated about thirty years ago, in Berkshire County, Mass., by Mr. John Carter.

CHURCHILL.

A variety said to have originated in Maine, and often sold in the market for the "State of Maine;" which it somewhat resembles in size, form, and color. Flesh yellow. Not a desirable sort. It is much inferior to the "State of Maine;" and, in many places, the latter variety has been condemned in consequence of the Churchill having been ignorantly cultivated in its stead.

CRISTY.

An early sort, of good quality, but rather unproductive. Shape somewhat long, though often nearly round; color white and purple, striped, and blended together. It is of no value as an agricultural variety; and, for table use, cannot be considered superior to many other varieties equally healthy and more prolific.

CUPS.

Introduced. Plant upright, stocky, surviving till frost; flowers pale purple; tubers pink or reddish, large, oblong, often irregular; flesh dry and farinaceous. Very healthy and productive, but better suited for agricultural purposes than for the table.

DANVERS SEEDLING.

Danvers Red.

Plant healthy and vigorous. The large, full-grown tubers are long; and the smaller, undeveloped ones, nearly round. Color light red, with faint streaks of white; eyes moderately sunk; quality fair.

This variety originated in Danvers, Essex County, Mass.; and, when first introduced, was not only of good size and quality, but remarkably productive. It has, however, much deteriorated; and is now, both as respects quality and yield, scarcely above an average. At one period, it had the reputation of being one of the best varieties for keeping, and of entirely withstanding the attacks of the potato disease.

DAVIS'S SEEDLING.

This variety originated in the town of Sterling, Mass.; and was early disseminated through the influence of the Massachusetts Horticultural Society, at whose exhibitions it attracted much attention on account of its size and beauty. For general cultivation, it is probably one of the most profitable sorts known, as it yields abundantly, even with ordinary attention. Under a high state of cultivation, seven hills have produced a bushel of potatoes.

The tubers are of good size, red, nearly round, though sometimes more or less flattened. Eyes deeply sunk, and not very numerous; flesh nearly white, slightly tinged with pink beneath the skin when cooked; quality good, being dry, farinaceous, and well flavored. It requires the full season for its complete perfection, and resists disease better than most varieties. As a winter potato, or for extensive cultivation for market, it is one of the best of all varieties; and commends itself to the farmer, both as respects quality and yield, as being greatly superior to the Peach-blow, Pink-eye, Vermont White, and many similar varieties, which so abound in city markets.

DYKEMAN.

Plant of medium strength and vigor, rarely producing seed or blossoms; tubers large, roundish, often oblong; color white, clouded at the stem-end and about the eyes (which are moderately sunk and rather numerous) with purple; flesh white, or yellowish-white, its quality greatly affected by season, and the soil in which the variety may be cultivated. In certain descriptions of rather strong, clayey land, the yield is often remarkably great, and the quality much above medium. In such land, if warm and sheltered, the tubers attain a very large size quite early in the season, and find a ready sale in the market at greatly remunerative prices. Under other conditions, it frequently proves small, waxy, and inferior in quality, and profitless to the cultivator. Notwithstanding these defects, its size, earliness, and productiveness render it worthy of trial.

EARLY BLUE.

Tubers of medium size, roundish, of a bright purple or bluish color; eyes moderately deep; flesh, when cooked, white, or yellowish-white, mealy, and well flavored.

This old and familiar variety is one of the earliest of the garden potatoes, of fine quality, and one of the best for forcing for early crops. It retains its freshness and flavor till late in the spring; is of comparatively healthy habit; and, though but moderately productive, is worthy more general cultivation.

EARLY COCKNEY.

Plant of medium strength and vigor, recumbent, rarely blossoming, and usually ripening and decaying early in the season, or before the occurrence of frost; tubers white, large, roundish, rough; flesh yellowish-white, or nearly white, dry, farinaceous, and of good flavor; hardy, moderately productive, and recommended as a desirable intermediate variety for the garden or for field culture. Introduced.

EARLY MANLY.

Plant medium or small, rarely blossoming, and decaying early in the season; tubers of medium size, white, roundish; flesh yellowish-white, dry, mealy, and mild flavored. It yields well, and is a good variety for early garden culture. Introduced.

FLOUR-BALL.

Plant reclining, of rather slender habit, rarely blossoming; tubers of medium size, white, round, the skin quite rough or netted; flesh white, dry, farinaceous, and mild flavored. It yields abundantly, and is a good sort for the garden; but would prove less profitable for growing for the market than many other varieties of larger size.

FLUKE KIDNEY. _Cot. Gard._

Plant vigorous, with luxuriant, deep-green foliage; continuing its growth till late in the season, or until destroyed by frost. The tuber is remarkable for its singular shape, of a flattened oval, frequently measuring eight or nine inches in length by nearly three inches in width. The peel is thin, and remarkably free from eyes; the surface, very smooth and even; the flesh is very dry, mealy, and farinaceous, exceedingly well flavored, and, in general excellence, surpassed by few, if any, of the late varieties. It is also healthy, hardy, and very productive; but is much better towards spring than when used soon after being harvested.

The variety originated near Manchester, Eng., about the year 1844; and appears to be a cross or hybrid between the Lapstone Kidney and Pink-eye.

In this country, the variety has never reached the degree of excellence it appears to have attained in England. With us the yield has been small, and it has suffered greatly from disease. The flesh is also yellow when cooked, and quite strong flavored. Not recommended for cultivation.

FORTY-FOLD.

An English variety. Plant healthy, ripening about the middle of September, rarely producing seed or blossoms; tubers white, of medium size, round; skin rough or netted; flesh white, comparatively dry, and well flavored. It yields abundantly; is a good kind for forcing; and, though the plants remain green until frost, the tubers attain a suitable size for use quite early in the season. An English sort, known as Taylor's Forty-fold, is quite distinct; the tubers being oval, much flattened, and of a reddish color.
