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
Caius Flaminius was a Roman general. He was tribune in 232 BC, praetor in 227, consul in 223, censor in 220, and again consul in 217. He had a triumph for defeating the Insubrian Gauls; and during his second consulship he constructed the Flaminian Way and built a circus. In 217 he was sent against Hannibal into Etruria, and was defeated and killed in the battle of Lake Thrasymenus . Research Caius Flaminius
Censors were two officers in ancient Rome who held office for eighteen months, and whose business was to draw up a register of the citizens and the amount of their property, for the purposes of taxation; to keep watch over the morals of the citizens, for which purpose they had power to censure vice and immorality by inflicting a public mark of ignominy on the offender; and to superintend the finance administration and the keeping up of public buildings. The office was the highest in the state next to the dictatorship, and was invested with a kind of sacred character. The term is now applied to an officer empowered to examine books before publication. Research Censor
Caius Julius (more popular known as Julius Caesar or Caesar) was a great Roman general, statesman, and historian. He was born in 100 BC and died in 44. He was the son of the praetor Caius Julius Caesar, and of Aurelia, a daughter of Aurelius Cotta. At the age of sixteen he lost his father, and shortly after he married Cornelia, the daughter of Lucius Cinna, the friend of Marius. This connection gave great offence to Sulla, the dictator, who proscribed him for refusing to put away his wife. His friends obtained his pardon with difficulty, and Caesar withdrew from Rome, and went to Asia, serving his first campaign under M. Minucius Thermus, the praetor in Asia.
On the death of Sulla, Caesar returned to Rome, where he distinguished himself as an orator. He afterwards visited Rhodes, when he was taken by pirates, and compelled to pay fifty talents for his release. To revenge himself, he fitted out some vessels at Miletus, overtook the pirates, made the greater number of them prisoners, and had them crucified before Pergamus. He now returned to Rome, where his eloquence and liberality made him very popular. He was pontifex maximus in 63 BC, praetor in 62 BC, and governor of Spain in 61 BC.
On his return to Rome, having united with Pompey and Marcus Crassus in the memorable coalition called 'the first triumvirate,' he became consul, and then obtained the government of Gaul with the command of four legions.
His military career was rapid and brilliant. He compelled the Helvetii, who had invaded Gaul, to retreat to their native country, subdued Ariovistus, who at the head of a German tribe had attempted to settle in the country of the AEdui, and conquered the Belgae. In nine years he reduced all Gaul, crossed the Rhine twice (in 55 BC and 53 BC), and twice passed over to Britain, defeated the gallant natives of this island in several battles, and compelled them to give him hostages.
The senate had continued his government in Gaul for another period of five years, while Pompey was to have the command of Spain, and Marcus Crassus that of Syria, Egypt, and Macedonia for five years also. But the death of Marcus Crassus in his campaign against the Parthians dissolved the triumvirate; and about the same time the friendship between Caesar and Pompey cooled. The senate, influenced by Pompey, ordered that Caesar should resign his offices and command within a certain time, or be proclaimed an enemy to the state, and appointed Pompey general of the army of the Republic. Upon this Csesar urged his soldiers to defend the honour of their leader, passed the Rubicon (in 49 BC), and made himself master of Italy without striking a blow, Pompey retiring into Greece. Caesar then levied an army with the treasures of the state, and hastened into Spain, which he reduced to submission without coming to a pitched battle with Pompey's generals.
He next conquered Massilia (now Marseilles), and returned to Rome, where he was appointed dictator. He then followed Pompey into Greece, and defeated him at Pharsalia, from which Pompey escaped only to be assassinated in Egypt. In Rome the senate and the people strove eagerly to gain the favour of the victor. They appointed him consul for five years, dictator for a year, and tribune of the people for life. When his dictatorship had expired he caused himself to be chosen consul again, and without changing the ancient forms of government, ruled with almost unlimited power. In 46 BC he crossed to Africa, defeated the Pompeians Scipio and Cato at Thapsus, and returning to Rome he was received with the most striking marks of honour. The term of his dictatorship was prolonged to ten years, the office of censor conferred on him alone; his person was declared inviolable, and his statue placed beside that of Jupiter in the capitol.
He soon after was honoured with four several triumphs, made perpetual dictator, and received the title of imperator with full powers of sovereignty. In February, 44, he declined the diadem which Antony publicly offered him, and next morning his statues were decked with diadems. His glory, however, was short lived, for a conspiracy was set on foot by his enemy Cassius, and joined by many of his own friends, including M. Brutus; and, notwithstanding dark hints had been given to him of his danger, he attended a meeting of the senate on 15th (ides) March, 44 BC, and fell beneath the daggers of the conspirators.
Of his writings, we still possess the history of his wars with the Gauls and with Pompey. Caesar was undoubtedly the foremost man of all this world, being great as a statesman, a general, an orator, a historian, and an architect and engineer, and his assassination was brought about more by jealousy and envy than by real patriotism.

Marcus Porcius Cato (Cato the Censor) was a Roman soldier. He was born in 234 BC at Tusculum and died in 149 BC. He inherited from his father, a plebeian, a small estate in the territory of the Sabines, which he cultivated with his own hands. He served his first campaign, at the age of seventeen, under Fabius Maximus, was present at the siege of Capua in 214 BC; and five years after fought under the same commander at the siege of Tarentum.
After the war was ended he returned to his farm, but by the advice of Valerius Flaccus removed to Rome, where his forensic abilities had free scope. He rose rapidly, accompanied Scipio to Sicily as quaestor in 204 BC, became an aedile in 199, and in 198 was chosen praetor, and appointed to the province of Sardinia. Three years later he gained the consulship, and in 194 for his brilliant campaign in Spain obtained the honour of a triumph. In 191 he served as military tribune against Antiochus, and then, having abundantly proved his soldierly qualities, returned to Rome.
For some years he exercised a practical censorship, scrutinizing the characters of candidates for office, and denouncing false claims, peculations, etc. His election to the censorship in 184 set an official seal to his efforts, the unsparing severity of which has made his name proverbial. From that year until his death, in 149, he held no public office, though zealously continuing his unofficial labours for the state. His hostility to Carthage, the destruction of which he advocated in every speech made by him in the forum, was the most striking feature of his closing years. His incessant Delenda est Carthago (Carthage must be destroyed) did much to further the third Punic war. Of his works his De Re Rusfcica (On Rural Economy) alone survives, though there exist in quotation fragments of his history and speeches.
Marrcus Porcius Cato (Cato of Utica) was a Roman reformer. He was born in 95 BC and died in 46 BC. He formed an intimacy with the StoicAntipater of Tyre, and ever remained true to the principles of the Stoic philosophy. He distinguished himself as a volunteer in the war against Spartacus, served as military tribune in Macedonia in 67 BC, was made quaestor in 65 BC.
His rigorous reforms won him general respect, and in 63 BC he was chosen tribune of the people. During the troubles with CatilineCato gave Marcus Cicero important aid both by his eloquence and sagacity, and at the same time set himself to thwart the ambitious projects of Pompey, Caesar, and Marcus Crassus. Such success as he had, however, was only temporary, and he failed to prevent the formation of the triumvirate. To get rid of him they sent him to take possession of Cyprus, but, having successfully accomplished his mission, he returned, opposed the Tribonian law for conferring extraordinary powers on the triumvirs, and in 54 BC enforced, as praetor, an obnoxious law against bribery.
On the breach between Pompey and Caesar he threw in his lot with Pompey, and guarded the stores at Dyrrhachium, while Pompey pushed on to Pharsalia. After receiving news of Pompey's defeat he sailed to Cyrene and effected a junction with Metellus Scipio at TJtica, in 47 BC. He took command of that city, but its defence appearing hopeless after the defeat of Scipio at Thapsus, he determined on suicide, and after spending some time in the perusal of the Phaedo of Plato, stabbed himself with his sword. His wounds were bound up by his attendants, but he tore off the bandages and died. Research Marcus Cato
Valerian (Publius Licinius Valerianus) was a Roman Emperor from 253 to 260. He was born in 190 and died in 266. A leading sen ator, and censor in 251, he was sent by the emperor Gallus against the upstart emperor Aemilianus on the Danube, but both Gallus and Aemilianus were murdered, and Valerian, who had been proclaimed emperor in Rhaetia, was acknowledged by the senate. A good soldier and administrator, he deputed his son Gallienus to rule the west, and, after defeating the Goths, in 257, he recovered Antioch from the invading Persians, and pursued their king Shapur I to the Euphrates, but was captured near Edessa, in 260, and lived for the rest of his life in ignominious captivity.

Opium is the dried, milky juice (latex) of unripe capsules of the white poppy also known as the opium poppy (Papaver somniferum), a plant probably indigenous in the south of Europe and western Asia, but now so widely cultivated that its original habitat is uncertain.
The medicinal properties of the juice have been recognized from a very early period. It was known to Theophrastus and appears in his time to have consisted of an extract of the whole plant, since Dioscorides about 77 AD draws a distinction between different types of opium, one of which he describes as an extract of the entireherb, and the more active form derived from the capsules alone. From the 1st to the 12th century the opium of Asia Minor appears to have been the only kind known in commerce. In the 13th century opium thebaicum is mentioned by Simon Januensis, physician to Pope Nicholas IV.
In the 16th century opium is mentioned by Pyres in 1516 as a production of the kingdom of Cous (Kuch Behar, south-west of Bhutan) in Bengal and of Malwa. Its introduction into India appears to have been connected with the spread of Islam. The opium monopoly was the property of the Great Mogul and was regularly sold. In the 17th century Kaempfer describes the various kinds of opium prepared in Persia, and states that the best sorts were flavoured with spices and called theriaka. These preparations were held in great esteem during the Middle Ages, and probably supplied to a large extent the place of the pure drug.
Opium is said to have been introduced into China, probably by the Arabs around 1280-1295, during the reign of Taitsu, and its use seems to have temporarily ceased in 1368. It appears to have been commonly used in that country as a medicine before the trade with India started. In a Chinese herbal compiled prior to the 17th century both the plant and its inspissated juice are described, together with the mode of collecting it, and in the General History of the Southern Provinces of Yunnan, revised and republished in 1736, opium is noticed as a common product up to this date, however, it was imported in comparatively small quantity by the Chinese solely as a remedy for dysentery, diarrhoea, and fevers, and was usually brought from India by junks as a return cargo.
In 1757 the monopoly of opium cultivation passed into the hands of the East India Company through the victory of Clive at Plassey. Up to 1773 the trade with China had been in the hands of the Portuguese, but the quantity annually exported to that country rarely exceeded 200 chests. In that year the East India Company took the trade under their own charge, and in 1776 the annual export reached 1000 chests, and 4054 chests in 1790. Although the importation was forbidden by the Chinese emperor Keaking in 1796, and opium-smoking punished with severe penalties, which were ultimately increased to transportation and death, the trade continued and had increased during 1820-1830 to 16,877 chests per annum. In 1839 a proclamation was issued threatening hostile measures if the English opium ships serving as depots were not sent away. The demand for removal not being complied with, 20,291 chests of opium (of 149.3 Ib each), valued at 2,000,000 pounds sterling, were destroyed by the Chinese commissioner Lin; but still the British sought to smuggle cargoes on shore, and some outrages committed on both sides led to an open war, which was ended by the treaty of Nanking in 1842. From that time until the end of the 19th century, in spite of the remonstrances of the Chinese Government, the exportation of opium from India to China continued, having increased from 52,925 piculs (of 133.3 Ib) in 1850 to 96,839 piculs in 1880. It appears to be certain, however, that, while the court of Peking was endeavouring to suppress the foreign trade in opium from 1796 to 1840, it did not or could not put a stop to the home cultivation of the drug, since a Chinese censor in 1830 represented to the throne that the poppy was grown over one-half of the province of Chekeang, and in 1836 another, Cho Tsun, stated that the annual produce of opium in Yunnan could not be less than several thousand piculs.
In 1885 it was estimated that south-western China, including Szechuen, produced not less than 224,000 piculs, while the entire import from India did not exceed 100,000 piculs. Opium was then produced in nine out of the eighteen provinces of China. The comparative cheapness of the Chinese opium, the lighter duties levied upon it, and the increasing care taken in its cultivation were enabling it to compete successfully with the Indian drug even in eastern China, where, however, it was hitherto chiefly used to mix with and cheapen the foreign article.
The amount of opium imported into Great Britain in 1861, 1871, and 1881 was 284,005, 591,466, and 793,146 lbs respectively, and the exports for the same years 290,120, 307,399, and 401,883 lb.
The method of cultivationa nd manufacture varies between countries, but generally the opium poppy is cultivated from seeds sown between November and March, and successive crops are ready from May to July. The flowers are white or purplish, there being different varieties of opium poppies; and a few days after the petals have fallen, when the capsules are about 25 mm. in diameter, they are cut round the middle with a knife, and left overnight for the juice to flow out and harden. After further drying on poppy leaves, the dark, plastic masses are made into lumps for sale.
Opium is bitter, and has a characteristic smell. Its properties depend upon the nineteen or twenty alkaloids it contains. The chief of these are: Morphine (9 per cent); narcotine (5 per cent); papaverine (0.8 per cent) ; thebaine (0.4 per cent); codeine or methylmorphine (0.3 per cent); narceine (0,2 per cent.). Morphine, the most important alkaloid, is separated from the others by extracting the opium with hot water, and boiling the extract with milk of lime. Alcoholic tincture of opium is known as laudanum. It contains about 0.75 per cent, of morphine.
Opium is used medicinally, mainly to relieve pain and to produce sleep, and for this purpose is best given hypodermically as morphine. It is also employed to relieve vomiting and to stop diarrhoea, to lessen distressing coughing, to stop bleeding in the stomach and intestines; while it is valuable in heart disease, diabetes, in cystitis and other inflammatory conditions, for haemoptysis, and, as Dover's powder, to cause perspiration in, for instance, common cold.
A conference of the Powers at the Hague in January 1912, drew up a convention of twenty-five articles by which they agreed to control the supply of and gradually suppress the manufacture of opium. Research Opium
Appius Claudius surnamed Caecus, or the blind, was an ancient Roman. He was elected censor in 312 BC, an office he held four years. While in this position he made every effort to weaken the power of the plebs, and constructed the road and aqueduct named after him. He was subsequently twice consul, and once dictator. In his old age he became blind, but in 280 BC he made a famous speech in which he induced the senate to reject the terms of peace fixed by Pyrrhus. He is the earliest Roman writer of prose and verse whose name we know. Research Appius Claudius
