Agriculture is the art of cultivating the ground, more especially with the plough and in large areas or fields, in order to raise grain and other crops for man and beast; including the art of preparing the soil, sowing and planting seeds, removing the crops, and also the raising and feeding of cattle or other live stock. This art is the basis of all other arts, and in all countries coeval with the first dawn of civilization. At how remote a period it must have been successfully practised in Egypt, Mesopotamia, and China we have no means of knowing, but archaeologists have found evidence of agriculture being practised around 7000 BC. Egypt was renowned as a corn country in the time of the Jewish patriarchs, who themselves were keepers of flocks and herds rather than tillers of the soil. Naturally very little is known of the methods and details of agriculture in early times, though field archaeologists at Butser Ancient Farm in Hampshire have been conducting experiments for some years.
Among the ancient Greeks the implements of agriculture were very few and simple. Hesiod, who wrote a poem on agriculture as early as the eighth century BC, mentions a plough consisting of three parts, the share-beam, the draught-pole, and the plough-tail, but antiquarians are not agreed as to its exact form. The ground received three ploughings, one in autumn, another in spring, and a third immediately before sowing the seed. Manures were applied, and the advantage of mixing soils, as sand with clay or clay with sand, was understood. Seed was sown by hand, and covered with a rake. Grain was reaped with a sickle, bound in sheaves, thrashed, then winnowed by wind, laid in chests, bins, or granaries, and taken out as wanted by the family, to be ground.
Agriculture was highly esteemed among the ancient Romans. Cato, the censor, who was celebrated as a statesman, orator, and general, derived his highest honours from having written a voluminous work on agriculture. In his Georgics Virgil has thought the subject of agriculture worthy of being treated in the most graceful and harmoniousverse. The Romans used a great many different implements of agriculture. The plough is represented by Cato as of two kinds, one for strong, the other for light soils. Yarro mentions one with two mould-boards, with which, he says, 'when they plough, after sowing the seed, they are said to ridge'. Pliny mentions a plough with one mould-board, and others with a coulter, of which he says there were many kinds. Fallowing was a practice rarely deviated from by the Romans. In most cases a fallow and a year's crop succeeded each other. Manure was collected from nearly or quite as many sources as have been resorted to by the moderns. Irrigation on a large scale was applied both to arable and grasslands.
The Romans introduced their agricultural knowledge among the Britons, though it is known that the Britons were already practising agriculture, and during the most flourishing period of the Roman occupation large quantities of corn were exported from Britain to the Continent. During the time that the Angles and Saxons were extending their conquests over the country agriculture may have been neglected; but afterwards it was practised with some success among the Anglo-Saxon population, especially, as was generally the case during the middle ages, on lands belonging to the church. Swine formed at this time a most important portion of the live stock, finding plenty of oak and beech mast to eat.
The feudal system introduced by the Normans, though beneficial in some respects as tending to ensure the personal security of individuals, operated powerfully against progress in agricultural improvements. War and the chase, the two ancient and deadliest foes of husbandry, formed the most prominent occupations of the Norman princes and nobles. Thriving villages and smiling fields were converted into deer forests, vexatious imposts were laid on the farmers, and the serfs had no interest in the cultivation of the soil. But the monks of every monastery retained such of their lands as they could most conveniently take charge of, and these they cultivated with great care, under their own inspection, and frequently with their own hands. The various operations of husbandry, such as manuring, ploughing, sowing, harrowing, reaping, thrashing, winnowing, etc, are incidentally mentioned by the writers of those days; but it is impossible to collect from them a definite account of the manner in which those operations were performed.
The first English treatise on husbandry and the best of the early works on the subject was published in the reign of Henry VIII in 1534, by Sir A Fitzherbert, judge of the Common Pleas. It is entitled the Book of Husbandry, and contains directions for draining, clearing, and inclosing a farm, for enriching the soil, and rendering it fit for tillage. Lime, marl, and fallowing are strongly recommended. The subject of agriculture attained some prominence during the reign of Elizabeth I. The principal writers of that period were Tusser, Googe, and Sir Hugh Platt. Tusser's Five Hundredth Points of Good Husbandry (first complete edition published in 1580) conveys much useful instruction in metre, but few works of this time contain much that is original or valuable.
The first half of the seventeenth century produced no systematic work on agriculture, though several on different branches of the subject. About 1645 the field cultivation of red clover was introduced into England, the merit of this improvement being due to Sir Richard Weston, author of a Discourse on the Husbandry of Brabant and Flanders. The Dutch had devoted much attention to the improvement of winter roots, and also to the cultivation of clover and other artificial grasses, and the farmers and proprietors of England soon saw the advantages to be derived from their introduction. The cultivation of clover soon spread, and Sir Richard Weston seems also to have introduced turnips. Potatoes had been introduced during the latter part of the sixteenth century, but were not for long in general cultivation. A number of writers on agriculture appeared in England during the Commonwealth, the most important works on the subject being Blythe's Improver Improved and Hartlib's Legacy. The former writer speaks of a rotation, or rather alternation of crops, and well knew the use of lime, as also of other manures. In the eighteenth century the first name of importance in British agriculture is that of Jethro Tull, a gentleman of Berkshire, who began to drillwheat and other crops about the year 1701, and whose Horse-hoeing Husbandry was published in 1731.
Jethro Tull was a great advocate of the system of sowing crops in rows or drills with an interval between every two or three rows wide enough to allow of ploughing or hoeing to be carried on. After the time of Jethro Tull's publication no great alteration in British agriculture took place, until Robert Bakewell and others effected some important improvements in the breeds of cattle, sheep, and swine, in the latter half of the eighteenth century. The raising and maintenance of live stock, especially of sheep, was a characteristic of English farming from a very early time, and for several centuries the country had almost a monopoly in the supply of wool. To Bakewell we owe the breed of Leicestersheep. By the end of the nineteenth century it was a common practice to alternate green crops with grain crops, instead of exhausting the land with a number of successive crops of corn. A well-known writer on agriculture at this period, and one who did a great deal of good in diffusing a knowledge of the subject, was Arthur Young.
Scotland was for a long time behind England in agricultural progress. Great progress was made during the eighteenth century, however, especially in the latter half of it, turnips being introduced as a field-crop, and new implements such as the swing-plough and the thrashing-machine coming into general use. The construction of good roads through the country also gave agriculture a great impulse. During the wars caused by the French revolution of 1795 to 1814 the high price of agricultural produce led to an extraordinary improvement in agriculture all over Britain. The establishment of the institution called the National Board of Agriculture was also of very great service to British husbandry at this period. Though a private association it was assisted by an annual parliamentary grant, and prizes were given by it for the encouragement of experiments and improvements in agriculture. It existed from 1793 to 1816.
Among other societies which have greatly furthered the progress of agriculture in Britain, the chief are the Royal Agricultural Society of England, established in 1838; the Highland and Agricultural Society of Scotland, founded in 1783; and the Royal Agricultural Society of Ireland, instituted in 1841. The objects of these and similar societies were such as the following: to encourage the introduction of improvements in agriculture; to encourage the improvement of agricultural implements and farm buildings; the application of chemistry to agriculture; the destruction of insects injurious to vegetation; to promote the discovery and adoption of new varieties of grain, or other useful vegetables; to collect information regarding the management of woods, plantations, and fences; to improve the education of those supported by the cultivation of the soil; to improve the veterinary art; to improve the breeds of live stock, etc. Shows are held, at which prizes are distributed for live stock, implements, and farm produce.
Through the efforts of the above-mentioned and other societies, the investigations of scientific men, the general diffusion of knowledge among all classes, and the necessity of competing with producers in foreign countries, agriculture made vast strides in Britain during the nineteenth century. Among the chief improvements were deep ploughing and thoroughdraining By the introduction of new or improved implements the labour necessary to the carrying out of agricultural operations was greatly diminished, as by the steam thrashing-machine, the steam-plough, and the reaping-machine. The nineteenth century saw also the introduction of chemistry into agriculture in Britain. The organization of plants, the primary elements of which they are composed, the food on which they live, and the constituents of soils, were all investigated, and most important results obtained particularly with regard to manures and rotations. Artificial manures, in great variety to supply the elements wanted for plant growth, came into common use at the end of the nineteenth century, not only increasing the produce of lands previously cultivated, but extending the limits of cultivation itself. An improvement in all kinds of stock became more and more general, feeding was conducted on more scientific principles, and improved varieties of plants used as field crops were introduced at the same time. At the end of the nineteenth century was introduced the system of ensilage for preserving fodder in a green state. However, by the start of the 20th century writers were proclaiming that, chiefly owing to foreign competition, agriculture had become a very unprofitable industry in Britain.
It is only since the nineteenth century that much progress was made in perfecting implements and machinery for cultivating the soil, sowing seed, drilling, rolling, hoeing, reaping, digging, etc. The first application of steam to ploughing dates from 1770, when Richard Edgeworth took out a patent for a steam ploughing machine, but it was 1852 before such application proved of any economic value. As early as 1829 a reaping-machine was invented by the Reverend Mr. Bell of Carmylie, Forfarshire, which, in an improved form, was still in use at the start of the twentieth century when numerous mowing and reaping-machines of ingenious construction were also introduced, many of which not only cut down the grain, but also bind it up into sheaves. At the start of the twentieth century steam was extensively used as a motive power in thrashing, in chaff-cutting, turnip-slicing, and even in churning. Only to be replaced after the invention of the combustion engine with petrol-power. Mechanisation led to the enlargement of fields, with small fields being amalgamated by the destruction of separating hedgerows to enable mechanical tractors and other farm vehicles to operate efficiently. The effect upon wildlife in Britain was devastating, and public concern started to grow.
The Second World War revolutionized agriculture in Britain, and led to the development of intensive farming techniques known as 'factory farming' and new anonymous breeds of livestock being developed which mature very quickly. During the later half of the twentieth century the public in Britain rebelled against the inhumanity of intensive animal husbandry, typified by 'battery hens' in which thousands of hens are kept in individual tiny cages within massive warehouses, unable to stretch let alone move around, and free-range or more traditional animal husbandry started to reappear in commercial agriculture.
The twentieth century also saw the wide scale introduction of chemical fertilizers and insecticides, many of which were harmful to the consumers and from a public backlash emerged a return to traditional farming, known as organic farming. Research Agriculture
Boustrophedon is the name given to a method of writing or printing, alternatively from right to left and from left to right. Boustrophedon is found on Greek inscriptions of the remotest antiquity. It is called boustrophedon (turning like oxen), because in this way oxen used to plough a field. Research Boustrophedon
Chivalry is a term which indicates strictly the organization of knighthood as it existed in the middle agea, and in a general sense the spirit and aims which distinguished the knights of those times. The chief characteristics of the chivalric ages were a warlike spirit, a lofty devotion to the female sex, a love of adventure, and an undefinable thirst for glory. The Crusades gave for a time a religious turn to the spirit of chivalry, and various religious orders of knighthoodarose, such as the Knights of St John, the Templars, the Teutonic Knights, etc.
The education of a knight in the days of chivalry was as follows: In his twelfth year he was sent to the court of some baron or noble knight, where he spent his time chiefly in attending on the ladies, and acquiring skill in the use of arms, in riding, etc. When advancing age and experience in the use of arms had qualified the page for war, he became an esquire, or squire. This word is from the Latinscutum, a shield, it being among other offices the squire's business to carry the shield of the knight whom he served. The third and highest rank of chivalry was that of knighthood, which was not conferred before the twenty-first year, except in the case of distinguished birth or great achievements. The individual prepared himself by confessing, fasting, etc; religious rites were performed; and then, after promising to be faithful, to protect ladies and orphans, never to lie nor utter slander, to live in harmony with his equals, etc, he received the accolade, a slight blow on the neck with the flat of the sword from the person who dubbed him a knight. This was often done on the eve of battle, to stimulate the new knight to deeds of valour; or after the combat, to reward signal bravery.
The rules of chivalry only applied to the nobility. While knights on the battle field and in combat enjoyed rules of engagement and a degree of mutual respect - with the notable exception of the Battle of Agincourt where the captured French knights were murdered at the order of king Henry V - peasants, or the ordinary common folk, were slaughtered and raped by knights as though they were not human at all, and certainly not treated in a chivalrous fashion.

Historically the Democratic Party was the most important of the American political parties, having been in continuous existence since the end of the 18th century. The rise of such a party, as soon as national politics began under the new Constitution, was natural. The love of individual liberty rather than strong government, was native in the minds of most Americans. Those who felt this most strongly would be likely to look with apprehension upon the Federal Government, and the possibility of its encroaching upon the States under cover of the new Federal Constitution. They were therefore likely to be advocates of strict construction of the Constitution and of States' rights. To these elements of party feeling, which had drawn the Anti-Federalists together in 1788, was added a few years later the strong sympathy of many Americans with the French Revolution, and the desire that Government should aid France in her contest with England.
Thomas Jefferson put himself at the head of the party drawn together by agreement in these sentiments, and led them in opposition to the Federalists. The party took the name of Democratic-Republican. Before Monroe's administration its members were more commonly called Republicans, since then most commonly Democrats. From the first the party was strongest in the Southern States. From its origin in 1792 to 1801, it was in opposition. In 1798 and 1799, upon the passage of the Alien and Sedition laws, it took strong ground for States' rights in the Kentucky and Virginia Resolutions. The election of Jefferson. in 1801 brought it into power. The chief tenets of the party were, belief in freedom of religion, of politics, of speech and of the press, in popular rule, in peace, in economical government, in the utmost possible restriction of the sphere of government, in hospitality to immigrants, and in the avoidance of foreign complications.
Placed in control of the government, the majority of the party drifted away from its strict constructionist ground, and supported measures of a nationalizing character. After the War of 1812, the Federalist party went out of existence, and the Democratic party had complete possession of the field. In 1820, Monroe was re-elected without opposition. But opposing tendencies in the nation and in the party were already showing themselves, and preparing the way for a new party division, between the Whigs, advocates of protection and other nationalizing measures, and those Democrats who held to the old programme of States' rights and free trade and restricted government. With the accession of Jackson in 1829, new social strata came into power in the Democratic party, the widening of the suffrage giving it a more popular character. Managed by skilful politicians, not without the aid of the spoils system, the party won every Presidential election but two (1840, 1848) from this time to 1860, destroyed the US bank, annexed Texas, and carried the country through the war with Mexico. But meanwhile the slavery question, coming into increasing prominence, was gradually forcing a division between the Democrats of the South and the great body of those in the North, who were unwilling to go so far in the protection of slavery by national authority as was desired by their Southern allies. The final split came in the nominating convention of 1860.
Two candidates were nominated, Abraham Lincoln and the Republicans won the election, and the American Civil War broke out. Though many War Democrats aided the administration in preserving the Union, the party was discredited in the eyes of many by its previous connection with the Southern leaders and the pro-slavery cause, and won no Presidential election until that of 1884, when in the minds of many the war issues were extinct and economic questions had taken their place. Defeated in 1888, it was again successful in 1892. By the end of the 19th century the party was hardly more strict-constructionist than the Republican, nor more marked by devotion to States' rights and the party was mostly noted as the opponent of a high tariff.
By the end of the 20th century the differences between the Democratic party and Republicans had become blurred, though the Democratic party was generally perceived - not always accurately - as more left-wing or liberal than the Republicans. Research Democratic Party
In agriculture, draining is a method of improving the soil by withdrawing the water from it by means of channels that are generally covered over. The successful practice of draining in a great measure depends on a proper knowledge of the superficial strata, of their situation, relative degrees of porosity, etc. Some strata allow water to pass through them, while others more impervious force it to run or filtrate along their surfaces until it reaches more level ground below. In general where the grounds are in a great measure flat and the soils of materials which retain the excess of moisture, they require artificial means of drainage to render them capable of yielding good crops whether of' grain or grass.
The wetness of land which makes it inferior for agricultural purposes, may appear not only as surface-water but as water which flows through the lower strata, and to draw off these there are the two distinct operations of surface-draining' and under-draining. The rudest form of open drains are the deep furrows lying between high-backed ridges, and meant to carry off the surplus water after the soil is completely saturated, but in doing so they generally carry off also much of the best of the soil and of the manure which has been spread upon it. The ordinary ditch is a common form of water-course useful in certain cases, as in hill pastures. But covered drains at a depth of one metre or so are the common forms in draining agricultural lands. They are generally either stone-drains or tile-drains. Stone-drains are either formed on the plan of open culverts of various forms, or of small stones in sufficient quantity to permit a free and speedyfiltration of the water through them. The box-drain, for instance, is formed of flat stones neatly arranged in the bottom of the trench, the whole forming an open tube.
In tile-drains, tiles or pipes of burnt clay are used for forming the conduits. They possess all the qualities which are required in the formation of drains, affording a free ingress to water, while they effectually exclude vermin, earth, and other injurious substances.
Drainage tiles and pipes have been made in a great variety of forms, the earliest of which, since the introduction of thorough draining, was the horse-shoe tile, so called from its shape. These should always rest on soles, or flats of burned clay. Pipe tiles, which combine the sole and cover in one piece, have been made of various shapes, but the best form appears to be the cylinder.
An important department of draining is the draining off of the waters which are the sources of springs. Sometimes the judicious application of a few simple drains, made to communicate with the watery layers, will often dry swamps of great extent, where large sums of money, expended in forming open drains in the swamp itself, would leave it but little improved.
In the laying out of drains the first point to be determined is the place of outfall, which should always afford a free and clear outlet to the drains, and must necessarily be at the lowest point of the land to be drained. The next point to be determined is the position of the minor drains; in the laying out of which the surface of each field must be regarded as being made up of one or more planes, as the case may be, for each of which the drains should be laid out separately. Level lines are to be set out a little below the upper edge of each of these planes, and the drains must then be made to cross these lines at right angles. By this means the drains will run in the line of the greatest slope, no matter how distorted the surface of the field may be. All the minor drains should be made to discharge into mains or submains, and not directly into an open ditch or water-course. As a general rule there should be a main to receive the waters of the minor drains from every 5 acres.
The advantages of drainage are obvious. In the first place it allows the soil to be brought into a more suitable condition for the growth of plants, aiding in producing the finely-divided and porous state by which the roots and rootlets can spread themselves at will in order to obtain the needed supplies of food, air, and moisture. It also allows the sun's rays to produce their full effect on the soil and plants without being robbed of great part of it by the stagnant water. Research Draining
Enamel is a vitreous glaze of various colours fused to the surface of gold, silver, copper, and other substances. The art of enamelling, which is of great antiquity, was practised by the Assyrians and by the Egyptians, from whom it may have passed into Greece, and thence into Rome and its provinces, including Great Britain, where various Roman antiquities with enamelled ornamentation have been discovered. The enamelled gold cup given by King John to the corporation of Lynn, in Norfolk, proves that the art was known among the Normans. The Byzantines of the 10th century produced excellent cloisonne enamels on a gold base, the cloisonne process consisting in tracing the design in fillets of gold upon the gold plate and filling up the small moulds thus formed with enamels the design appearing in coloured enamels separated by thin gold partitions or cloisons. In some cases, however, the enamels were filled into hollows beaten out in the gold plate, which formed part of the field.
In the 12th century the town of Limoges acquired the high reputation for inlaid enamels which it held until the 14th century, aud re-acquired in the 16th for its painted enamels. The costliness of the sculptured ground had led the Italians early in the 14th century to substitute the practice of incising the design on the face of the plate, and then covering it with a transparent enamel. The further step, which made the Limousin workshops famous, consisted in the method of superficial enamelling, in which opaque colours or colours laid on a white opaque ground were used. The Limoges school degenerated greatly in the 17th century, but its method with certain modifications in detail is still employed.
The basis of all kinds of enamel is a perfectly transparent and fusibleglass, which is rendered either semitransparent or opaque by the admixture of metallic oxides. White enamels are composed by melting the oxide of tin with glass, and adding a small quantity of manganese or phosphate of calcium to increase the brilliancy of the colour. The addition of the oxide of lead, or antimony, or oxide of silver, produces a yellow enamel. Reds are formed by copper, and by an intermixture of the oxides of gold and iron. Greens, violets, and blues are formed from the oxides of copper, cobalt, and iron.
In the middle of the 18th century enamelling was largely applied to the decoration of snuff-boxes, tea-canisters, candlesticks, and other small articles. Of later years it was extensively applied to the coating of iron vessels for domestic purposes, the protection of the insides of baths, cisterns, and boilers, and the like. Enamelling in colours upon iron was common, iron plates being thus treated by means of various mixtures, and words and designs of various kinds being permanently fixed upon them by stencilling, for advertising, signboards, etc.
From about 1760 onwards, the normal method of enclosing commons or open fields in Britain was by private Act of Parliament. The Act authorised the appointment of commissioners to survey the lands to be enclosed. A large- scale plan of the lands was prepared, to assist the commissioners to draw up an award allocating the land to individuals. These awards, with their plans, record the boundaries of the fields and the courses and widths of the roads and trackways as laid out afresh by the enclosure commissioners. Occasionally this is accompanied by a map showing the pre-enclosure picture of open-field farming, with much land remaining as commons. Research Enclosure Awards
Flint Implements were used by man while unacquainted with the use of metals. For such implements other hard stones were also used, but the most numerous were formed of flint. They consist of arrow-heads, axe-heads, lance-beads, knives, scrapers, etc. Those of the palaeolithic period were unpolished, those of the neolithic polished. Flint implements were still used by some aboriginal tribes at the start of the 20th century, and research and field tests conducted during the 20th century revealed that flint implements can be very effective, as effective or even more so than their metal counterparts for some tasks.
