AGRICULTURE

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 harmonious verse. 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 grass lands.

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 drill wheat 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 Leicester sheep. 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 thorough draining 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.

AMENDMENT

An amendment is a proposal brought forward in a meeting of some public or other body, either in order to get an alteration introduced on some proposal already before the meeting, or entirely to overturn such proposal. In parliament an amendment denotes an alteration made in the original draught of a bill whilst it is passing through the houses. Amendments may be made so as totally to alter the nature of the proposition; and this is a way of getting rid of a proposition, by making it bear a sense different from what was intended by the movers, who are thus compelled to abandon it.

ANTOINE DE FOURCROY

Antoine Francis de Fourcroy was a French chemist. He was born in 1755 and died in 1809. Having adopted the profession of medicine he applied himself closely to the sciences connected with it, and especially to chemistry. In 1784 he was made professor of chemistry at the Jardin du Roi; and the next year he was chosen a member of the Academy of Sciences. At this period he became associated with Lavoisier, Guyton-Morveau, and Berthollet in researches which led to vast improvements and discoveries in chemistry. When the French Revolution took place he was chosen a deputy from Paris to the national convention, but did not take his seat in that assembly until after the fall of Robespierre. In September, 1794, he became a member of the committee of public safety. In December, 1799, Bonaparte gave him a place in the council of state, in the section of the interior, in which place he drew up a plan for a system of public instruction, which, with some alteration, was adopted.

JOHN DRYDEN

John Dryden was a British poet. He was born in 1631 at Aldwinkle All-Saints, Northamptonshire and died in 1700. He was was descended from an ancient family, his grandfather being Sir Erasmus Dryden of Canons Ashby, Northamptonshire. He was admitted a king's scholar at Westminster under the celebrated Dr. Busby, whence he went to Trinity College, Cambridge, being here elected to a scholarship.

After university he appears to have settled at London in 1657, where he acted as secretary to his cousin Sir Gilbert Pickering, a favourite of Oliver Cromwell; and on the death of the Protector he wrote his Heroic Stanzas on that event. At the Restoration, however, he hailed the return of Charle II in Astraea Redux, and from that time his devotion to the Stuarts knew no decay.

In 1661 he produced his first play, The Duke of Guise; but the first that was performed was The Wild Gallant, which appeared in 1663 and was not a success. This was followed by The Rival Ladies, and The Indian Queen, a tragedy on Montezuma in heroic verse, written in collaboration with Sir Robert Howard, whose sister, Lady Elizabeth Howard, John Dryden married in 1663. He followed up The Indian Queen with The Indian Emperor, which at once raised John Dryden to the highest pitch of public estimation, an elevation which he retained until his death.

The great fire of London put a stop for some time to theatrical exhibitions. In the interval John Dryden published the Annus Mirabilis, an historical account of the events of the year 1666, one of the most elaborate of his productions. In 1668 he also published his celebrated Essay on Dramatic Poesy - the first attempt to regulate dramatic writing. In 1668 the Maiden Queen, a tragi-comedy, was represented. This was followed in 1670 by the Tempest, an alteration from William Shakespeare, in which he was assisted by Sir William Davenant. It was received with general applause, notwithstanding the very questionable taste and propriety of the added characters.

John Dryden was shortly afterwards appointed to the offices of royal historiographer and poet-laureate, with a salary of 200 pounds a year. He now became professionally a writer for the stage, and produced many pieces, some of which have been strongly censured for their licentiousness and want of good taste. The first of his political and poetical satires, Absalom and Achitophel (Monmouth and Shaftesbury), was produced in 1681, and was followed by The Medal, a satire against sedition; and Mac Flecknoe, a satire on the poet Shadwell.

On the accession of James in 1685 John Dryden became a Roman Catholic, a conversion the sincerity of which has been not unreasonably regarded with suspicion, considering the time at which it occurred. At court the new convert was received with open arms, a considerable addition was made to his pension, and he defended his new religion at the expense of the old one in a poem, The Hind and the Panther. Among his other services to the new king were a savage reply to an attack by Stillingfleet, and panegyrics on Charles and James under the title of Britannia Rediviva.

At the Revolution John Dryden was deprived of the offices of poet-laureate and historiographer, and of the certain income which these offices secured him. During the remaining ten years of his life he produced some of his best work, including his admirable translations from the classics. He published, in conjunction with Congreve, Creech, and others, a translation of Juvenal, and one of Persius entirely by himself. About a third part of Juvenal was translated by John Dryden, who wrote an essay on satire which was prefixed to the whole. His poetic translation of Virgil appeared in 1697, and, soon after that masterpiece of lyric poetry, Alexander's Feast, his Fables, etc.

He died on May the 1st, 1700, at the age of sixty-nine, and was buried in Westminster Abbey. John Dryden is unequalled as a satirist among English poets, and the best of his tragedies are unsurpassed by any since written. His poetry as a whole is more remarkable for vigour and energy than beauty, but he did much to improve English verse. He was also an admirable prose writer. Personally he waa modest and kindly. The whole of his works, edited by Sir Walter Scott, were published in 1818 they were later re-published with additional notes, etc, by George Saintsbury.

STOKES GUN

The Stokes Gun was a British simple type of trench howitzer or trench mortar designed by Sir Wilfrid Stokes in 1915. The Stokes Gun consisted of a weldless steel barrel at an approximate angle of 45 degrees, reduced at the breech end and closed with a cap which terminated in a ball and internally carried a pointed striker. In the upper part of the barrel a sliding pin was arranged, which could be withdrawn by pulling a lanyard. The barrel was supported at its upper end on two struts, provided with screw adjustment for slight alteration of the elevation. The bomb or shell for the Stokes Gun consisted of a cylindrical case containing a charge of high explosive and equipped with an impact fuse. At the lower end was a tubular extension perforated with a number of holes. This extension accommodated a 12-bore sporting cartridge filled with propellant.

The bomb was placed in the mouth of the barrel of the Stokes Gun and rested upon the sliding pin until the lanyard was pulled, where upon the bomb slid down the barrel, and the cap of the cartridge struck against the point of the striker and was exploded. The gas generated by the propellant blew the bomb out of the gun. The cartridge-case was ejected with the bomb, so that as soon as one shot was fired another bomb could be put in. If rapid fire was desired, it was usual to lock the sliding pin in the 'fire' position, and bombs merely def into the muzzle and allowed to drop. Under such conditions it was possible to fire some 40 shots per minute. The original Stokes Gun had a bore of approximately three inches (76 mm) and the bombs weighed about 20 lb (9 kg) each, but later howitzers on the same principle were constructed up to 9.5 inches (240 mm) bore throwing bombs weighing 150 lb (68 kg) and from the Stokes Gun developed the modern mortar.

GOVERNOR

In mechanics, a governor is a contrivance for maintaining a uniform velocity with a varying resistance of a piece of machinery. Originally, governors were employed in steam engines and worked by regulating the amount of steam that passed. A common form of steam-engine governor consisted of a pair of balls suspended from a vertical shaft kept in motion by the engine. When the engine went too fast the balls flew farther asunder, and depressed the end of a lever, which partly shut a throttle-valve, and diminished the quantity of steam admitted into the cylinder; and on the other hand, when the engine went too slow, the balls fell down towards the spindle and elevated the valve, thus increasing the quantity of steam admitted into the cylinder. By this ingenious contrivance, therefore, the quantity of steam admitted to the cylinder was exactly
proportioned to the resistance of the engine, and the velocity kept constantly the same. A similar contrivance was employed in mills to equalize the motion of the machinery. When any part of the machinery was suddenly stopped, or suddenly set agoing, and the moving power remained the same, an alteration in the velocity of the mill would take place, and it moved faster or slower. A governor was used to remedy this.
