Agaricus campestrisAgaricus campestris, the Common Mushroom
Agar′ic(Agarĭcus), a large and important genus of fungi, characterized by having a fleshy cap or pileus, and a number of radiating plates or gills on which are produced the naked spores. The majority of the species are furnished with stems, but some are attached to the objects on which they grow by their pileus. Over a thousand species are known, and are arranged in five sections according to whether the colour of their spores is white, pink, brown, purple, or black. The chief British representatives are the common wild mushroom (A. campestris, L.), the Horse mushroom (A. arvensis, Schæff.),A. elvensis, B. and Br.,A. silvaticus, Schæff., &c. Many of the species are edible, like the common mushroom, and supply a delicious article of food, while others are deleterious and even poisonous.
Agaric Mineral,orMountain-meal,one of the purest of the native carbonates of lime, found chiefly in the clefts of rocks and at the bottom of some lakes in a loose or semi-indurated form resembling a fungus. The name is also applied to a stone of loose consistence found in Tuscany, of which bricks may be made so light as to float in water, and of which the ancients are supposed to have made their floating bricks. It is a hydrated silicate of magnesium, mixed with lime, alumina, and a small quantity of iron.
Aga′sias,a Greek sculptor of Ephesus, about 400B.C., whose celebrated statue, known as the Borghese Gladiator, representing a soldier contending with a horseman, is now in the Louvre, Paris.
Agassiz(ag′as-ē), Louis John Rudolph, an eminent naturalist, born 1807, died 1873, son of a Swiss Protestant clergyman at Motiers, near the eastern extremity of the Lake of Neufchâtel. He completed his education at Lausanne, and early developed a love of the natural sciences. He studied medicine at Zürich, Heidelberg, and Munich. His attention was first specially directed to ichthyology by being called on to describe the Brazilian fishes brought to Europe from Brazil by Martius and Spix. This work was published in 1829, and was followed in 1830 byHistoire Naturelle des Poissons d'eaux douces de l'Europe Centrale(Fresh-water Fishes of Central Europe). Directing his attention to fossil ichthyology, five volumes of hisRecherches sur les Poissons Fossilesappeared between 1834 and 1844. His researches led him to propose a new classification of fishes, which he divided into four classes, distinguished by the characters of the skin, as ganoids, placoids, cycloids, and ctenoids. His system has not been generally adopted, but the names of his classes have been taken as useful terms. In 1836 he began the study of glaciers, and in 1840 he published hisÉtudes sur les Glaciers, in 1847 hisSystème Glaciaire. From 1838 he had been professor of natural history at Neufchâtel, when in 1846 pressing solicitations and attractive offers induced him to settle in America, where he was connected as a teacher first with Harvard University, Cambridge, and afterwards with Cornell University as well as Harvard. After his arrival in America he engaged in various investigations and explorations, and published numerous works, including:Principles of Zoology, in connection with Dr. A. Gould (1848);Contributions to the Natural History of the United States(4 vols., 1857-62);Zoologie Générale(1854);Methods of Study in Natural History(1863). In 1865-6 he made zoological excursions and investigations in Brazil, which were productive of most valuable results.Agassiz held views on many important points in science different from those which prevailed among the scientific men of the day, and in particular he strongly opposed the evolution theory.

Agassiz(ag′a-sē), Mount, an extinct volcano in Arizona, United States, 10,000 feet in height; a place of summer resort, near the Great Cañon of the Colorado.
Ag′ate,a semi-translucent compound mineral mass formed in the cavities of rocks by the successive deposition of various types of silica, or by the staining of a siliceous mass thus deposited along concentric zones. Bands or layers of various colours blended together, the base generally being chalcedony, and this mixed with variable proportions of jasper, amethyst, quartz, opal, heliotrope, and carnelian. The varying manner in which these materials are arranged causes the agate when polished to assume some characteristic appearances, and thus certain varieties are distinguished, as the ribbon agate, the fortification agate, the zone agate, the star agate, the moss agate, the clouded agate, &c. In Scotland they are cut and polished under the name of Scottish pebbles.
Agathar′chus,a Greek painter, native of Samos, the first to paint a scene for the acting of tragedies. The view, however, that he applied the rules of perspective to theatrical scene-painting is doubtful. He flourished about 480B.C.
Agath′ias,a Greek poet and historian, born at Myrina, Asia Minor, aboutA.D.530; author of an anthology, a collection of love poems, and a history of his own times, which is our chief authority for the period 552-8, during which time the Byzantine army was struggling against the Goths, Vandals, and Franks.
Agathocles(a-gath′o-klēz), a Sicilian Greek, one of the boldest adventurers of antiquity, born 361B.C.By his ability and energy, and being entirely unscrupulous, he raised himself from being a potter to being tyrant of Syracuse and master of Sicily. Wars with the Carthaginians were the chief events of his life. He died at the age of seventy-two.
Ag′athon,a Greek tragic poet, a friend of Euripides, and contemporary with Socrates and Alcibiades, born about 445B.C., died about 402B.C.The banquet which he gave to celebrate his first dramatic victory was made the groundwork of Plato'sSymposium.
AgaveAgave (Agave americana)
Agave(a-gā′vē), a genus of plants, nat. ord. Amaryllidaceæ (which includes the daffodil and narcissus), popularly known as American aloes. They are generally large, and have a massive tuft of fleshy leaves with a spiny apex. They live for many years—ten to seventy according to treatment—before flowering. When this takes place, the tall flowering stem springs from the centre of the tuft of leaves, and grows very rapidly until it reaches a height of 15, 20, or even 40 feet, bearing towards the end a large number of flowers. The best-known species isA. americāna, known as the Maguey or 'tree of wonders', introduced into Spain in 1561, and now extensively grown in the warmer parts of this continent as well as in Asia (India in particular). This and other species yield various important products, the chief being the fibre obtained by maceration from the leaves and roots, and known commercially as American aloe, pita flax, or vegetable silk. The sap when fermented yields a beverage resembling cider, thepulquebeer of the Spaniards, or is distilled into an intoxicating spirit (Mezcal or Aguardiente). The leaves are used for feeding cattle; the fibres of the leaves are formed into thread, cord, and ropes, and are also good material for paper-making; an extract from the leaves is used as a substitute for soap; slices of the withered flower-stem are used as razor-strops.
Agde(a˙gd), a seaport of southern France, department of Hérault, with a cathedral, an ancient and remarkable structure. The trade, chiefly coasting, is extensive. Pop. 9265.
Age,a period of time representing the wholeor a part of the duration of any individual thing or being, but used more specifically in a variety of senses. In lawageis applied to the periods of life when men and women are enabled to do that which before, for want of years and consequently of judgment, they could not legally do. A male at twelve years old may take the oath of allegiance; at fourteen is at years of discretion, and therefore may choose his guardian or be an executor, although he cannot act until of age; and at twenty-one is at his own disposal, and may alienate and devise his lands, goods, and chattels. In English law a male at fourteen and a female at twelve may consent or disagree to marriage, but it cannot be celebrated without the consent of the parents or guardians until the parties are of age. A female at fourteen is at years of legal discretion, and may choose a guardian; at seventeen may be an executrix; and at twenty-one may dispose of herself and her lands. So that full age in male or female is twenty-one years, which age is completed on the day preceding the anniversary of a person's birth, who till that time is an infant, and so styled in law. In France majority is attained at twenty-one, whilst the marriageable age is eighteen for males and fifteen for females, subject to consent of parents or guardians. In England no one can take a seat in Parliament under twenty-one, be ordained a priest under twenty-four, nor made a bishop under thirty. In France a seat in the Chamber of Deputies may be taken only at twenty-five and in the Senate at forty. The law of Scotland divides life into three periods—pupilarity, minority, and majority. The first extends up to the time of legal puberty, that is, twelve years for a female and fourteen for a male, when they may marry; the second extends from this point up to twenty-one years, which is the time when majority is attained.
The term is also applied to designate the successive epochs or stages of civilization in history or mythology. Hesiod speaks of five distinct ages:—1. ThegoldenorSaturnian age, a patriarchal and peaceful age. 2. Thesilver age, licentious and wicked. 3. Thebrazen age, violent, savage, and warlike. 4. Theheroic age, which seemed an approximation to a better state of things. 5. Theiron age, when justice and honour had left the earth. The term is also used in such expressions as thedark ages, themiddle ages, theElizabethan age, &c.
TheArchæological AgesorPeriodsare three—the Stone Age, the Bronze Age, and the Iron Age, these names being given in accordance with the materials chiefly employed for weapons, implements, &c., during the particular period. The Stone Age of Europe has been subdivided into two—the Palæolithic or earlier, and Neolithic or later. The wordagein this sense has no reference to the lapse of time—or not necessarily so—but simply refers to the stage at which a people has arrived in its progress towards civilization; thus there are races still in their stone age. The Palæolithic or earlier stone age in Europe was doubtless immensely earlier than the Neolithic, the latter being marked by implements of much greater finish than the former. SeeStone Age.
Agen(a˙-zhan˙), one of the oldest towns in France, capital of department Lot-et-Garonne on the Garonne, 74 miles south-east of Bordeaux; see of a bishop; manufactures sailcloth and other articles, and has an extensive trade.

Ambassadors were originally styled diplomatic agents.—In India, it is the name for an officer to whom political power is given to deal with native states.—Army Agentis a kind of military banker, authorized by the Government to manage the monetary affairs of a regiment. There are only a few of these agents, and consequently each has in charge the affairs of a number of different regiments.—Crown Agentsare officials appointed by the secretary of state for the colonies to act as commercial and financial agents in this country for the different British colonies that are not self-governing; those that are self-governing appoint their own agents, who are designatedagents-general.—Agentin mechanics is the general force producing a movement.
Ageratum(a-jer′a-tum), a genus of composite plants of the warmer parts of America, one species of which,A. mexicānum, is a well-known flower-border annual with dense lavender-blue heads. From it have been derived several varieties with flowers of different colours used chiefly as bedding plants.
Ager Publicus.SeeAgrarian Law.
Agesilaus(a-jes-i-lā′us), a king of Sparta, born in 444B.C., and elevated to the throne after the death of his brother Agis II. He acquired renown by his exploits against the Persians, Thebans, and Athenians. Though a vigorous ruler, and almost adored by his soldiers, he was of small stature and lame from his birth. He died in Egypt in the winter of 361-360B.C.His life has been written by Xenophon, Plutarch, and Cornelius Nepos.
Agglom′erate,in geology, a collective name for masses consisting of angular fragments ejectedfrom volcanoes. When a rock mass consists largely of fragments worn and rounded by water it is called aconglomerate, and such masses were originally, no doubt, gravels and shingles on sea beaches and river channels.
Agglu′tinate Languages,languages in which the modifying suffixes are, as it were, glued on to the root, both it and the suffixes retaining a kind of distinctive independence and individuality, as in the Japanese, Turkish, and other Turanian languages, and the Basque language.
Agg′regate,a term applied in geology to rocks composed of several different mineral constituents capable of being separated by mechanical means, as granite, where the quartz, felspar, and mica can be separated mechanically.—In botany it is applied to flowers composed of many small florets having a common undivided receptacle, the anthers being distinct and separate, the florets commonly standing on stalks, and each having a partial calyx.
Aggry Beads,glass beads of various forms and colours, prized by the natives of West Africa as ornaments, and as having magical and medicinal virtues. Their origin and history are not well known. Such beads have been found in various parts of the world, including North and South America, and often in graves. Some authorities believe that the oldest of them are the work of the ancient Egyptians, or the Phœnicians, while the later are probably of Venetian origin.

Agincourt(a˙-zhan˙-kör), a village of Northern France, department Pas de Calais, famous for the battle of 25th Oct., 1415, between the French and English. Henry V, King of England, eager to conquer France, landed at Harfleur, took the place by storm, and wished to march through Picardy to Calais, but was met by a French army under the Constable d'Albret. The English numbered about 15,000 men, while the French numbers are variously given as from 50,000 to 150,000. The confined nature and softness of the ground were to the disadvantage of the French, who were drawn up in three columns unnecessarily deep. The English archers attacked the first division in front and in flank, and soon threw them into disorder. The second division fled on the fall of the Duc d'Alençon, who was struck down by Henry himself; and the third division fled without striking a blow. Of the French 10,000 were killed, including the Constable d'Albret, with six dukes and princes. The English lost 1600 men killed, among them the Duke of York, Henry's uncle. After the battle the English continued their march to Calais.
Agio(ā′ji-ō), the difference between the real and the nominal value of money, as between paper money and actual coin. It is used to denote both the difference between two currencies in the same country and the variations in the currencies of different countries.

He attempted a reform of the abuses which had crept into the State—his plan comprehending a redistribution of the land, a division of wealth, and the cancelling of all debts. Opposed by his colleague Leonidas, advantage was taken of his absence, in an expedition against the Ætolians, to depose him. Agis at first took sanctuary in a temple, but he was treacherously seized and strangled, after going through the form of a trial.

Agnostics(ag-nos′tiks; Gr.a, not,gignōskein, to know), a modern term invented by Huxley in 1869 and applied to those who disclaim any knowledge of God, the origin of the universe, immortality, &c. The agnostics, or adherents of this doctrine, hold that the mind of man is limited to a knowledge of phenomena and of what is relative, and that, therefore, the infinite, the absolute, and the unconditioned, being beyond all experience, are consequently beyond its range. Agnosticism is therefore the attitude of 'solemnly suspended judgment', and cannot be identified with atheism. The agnostics do not deny the existence of a Divine Being, but merely maintain that we have no scientific ground for either belief or denial.—Bibliography: Sir Leslie Stephen,An Agnostic's Apology; R. Flint,Agnosticism; J. Ward,Naturalism and Agnosticism.
Agnus Castus,a shrub,Vitex Agnuscastus, nat. ord. Verbenaceæ, a native of the Mediterranean countries, with white flowers and acrid, aromatic fruits. It had anciently the imagined virtue of preserving chastity—hence the termcastus(Lat., chaste).
Agnus Dei(dē′ī; Lat., 'the Lamb of God'), a term applied to Christ inJohn, i, 29, and in the Roman Catholic liturgy a prayer beginning with the words 'Agnus Dei', generally sung before the communion.

Agra′phia. SeeAphasia.
Agrarian Laws,laws enacted in ancient Rome for the division of the public lands, that is, the lands belonging to the State (ager publicus). As the territory of Rome increased, the public land increased, the land of conquered peoples being always regarded as the property of the conqueror. The right to the use of this public land belonged originally only to the patricians or ruling class, but afterwards the claims of the plebeians on it were also admitted, though they were often unfairly treated in the sharing of it. Hence arose much discontent among the plebeians, and various remedial laws were passed with more or less success. Indeed an equitable adjustment of the land question between the aristocracy and the common people was never attained.
Agravaine,Sir, one of the knights of the Round Table.

Agric′ola,Gnæus Julius, lived fromA.D.37 to 93, a Roman consul under the Emperor Vespasian, and governor in Britain, the greater part of which he reduced to the dominion of Rome; distinguished as a statesman and general. His life, written by his son-in-law, the historian Tacitus, gives the best extant account of Britain in the early part of the period of the Roman rule. He was the twelfth Roman general who had been in Britain, but was the only one who effectually subdued the southern portion of it and reconciled the Britons to the Roman yoke. This he did by teaching them the arts of civilization and to settle in towns. He constructed the chain of forts between the Forth and the Clyde, defeated Galgacus at the battle of Mons Graupius, and sailed round the island, discovering the Orkneys.
Agric′ola,Georg (originally Bauer, that is, peasant = Lat.agricola), born in Saxony 1490, died at Chemnitz 1555, German physician and mineralogist. Though tinged with the superstitions of his age, he made the first successful attempt to reduce mineralogy to a science, and introduced many improvements in the art of mining. A complete edition of his works was published at Basel in 1550 and 1558.
Agricola,Johann, the son of a tailor at Eisleben, was born in 1492, and called, from his native city,master of Eisleben(magister Islebius); one of the most active among the theologians who propagated the doctrines of Luther. In 1537, when professor in Wittenberg, he stirred up the Antinomian controversy with Luther and Melanchthon. He afterwards lived at Berlin, where he died in 1566, after a life of controversy. Besides his theological works he composed a work explaining the common German proverbs.
Agricola,Johann Friedrich, German musician and composer, born near Altenburg 1720, died at Berlin 1774; pupil of Sebastian Bach; wrote several operas, includingIphigenia in Tauris. He wrote under the pseudonym of 'Olibrio'.
Agricola,Rodolphus, German scholar, born at Groningen 1443, died at Heidelberg 1485. After travelling in France and Italy he was appointed professor of philosophy at Heidelberg, and did good service in transplanting the revived classical learning into Germany.
Ag′ricultureis 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 there is sufficient evidence of agriculture having attained considerable development many centuries before the Christian era. Egypt was renowned as a corn country in the time of the Jewish patriarchs, and had probably been so for centuries before. The hieroglyphics on ancient monuments furnish records of the early development of agriculture in Egypt and of the use of the plough and other agricultural implements. The advanced methods of the Egyptians and Syrians were introduced into Europe by the Saracens. Land culture also attained a more or less considerable development in ancient China and Hindustan. 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 centuryB.C., 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, and very full accounts are contained in the works of Pliny, Virgil, Cato, Varro, and Palladius. 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. Varro 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 various sources, and irrigation was practised on a large scale.
The Romans introduced their agricultural knowledge among the Britons, 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 must have been greatly 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, &c., 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.
While there is much in the writings of the old English chroniclers concerning the tenure of land, upon which subject theDomesday Bookgives much enlightenment, there is a great lack of information as to the manner in which the land was cultivated. Information began to be recorded in the middle of the thirteenth century, but only one treatise is known to have been written, namely,La Dite de Husbanderye, an essay in Norman French by Walter de Henley. This work was superseded by another treatise, the best of the early works on the subject, and published in the reign of Henry VIII (in 1523)by Sir A. Fitzherbert, judge of the Common Pleas. It is entitled theBook of Husbandry, and contains directions for draining, clearing, and enclosing 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. The principal writers of that period were Tusser, Googe, and Sir Hugh Platt. Tusser'sFive Hundreth Pointes 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 aDiscourse on the Husbandry of Brabant and Flanders, to whom also belongs the credit of first growing turnips in England. 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. 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'sImprover Improvedand Hartlib'sLegacy. 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 whoseHorse-hoeing Husbandrywas published in 1731. 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. This enabled the ground to be cleared with crops still growing, thus obviating the necessity for 'bare fallow' and leading to thefour-courseor Norfolk Rotation of Charles, second Viscount Townshend, the first agriculturist to cultivate turnips on a large scale. After the time of Tull and Townshend no great alteration in British agriculture took place till 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 well-known breed of Leicester sheep. By the end of the 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 (1795-1815) 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 in existence at the present day are the Smithfield Club, inaugurated in 1798; 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 are 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, &c. 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 madevast strides in Britain during the nineteenth century and the beginning of the twentieth. Among the chief improvements we may mention deep ploughing and thorough draining. By the introduction of new or improved implements the labour necessary to the carrying out of agricultural operations has been greatly diminished, and advancement in this direction has been promoted by the necessities of the Great War. Labour-saving machinery is likely to be used in future on an increasingly large scale. Science, too, has been called in to act as the handmaid of art, and in its application we owe very much to the researches conducted at the Rothamsted Experimental Station, founded in 1834 by Lawes, who endowed the Lawes Trust in 1889. Gilbert and he worked together from 1843 to the end of last century. It is primarily by the investigations of the chemist and physicist that agriculture has been put on a really scientific basis. The physiology of plants and animals, and the complex properties of soils, have all been investigated, and most important results obtained. Artificial manures, in great variety to supply the elements wanted for plant growth, have come into common use, and the free nitrogen of the air is now worked up into various substances by which the nitrate of soda imported from South America can be replaced. An improvement in all kinds of stock is becoming more and more general, feeding is conducted on more scientific principles, and improved varieties of crop-plants are created by applying the principles of Mendel and other scientists. Much attention is also devoted to seed-testing, and the applications of electricity to agriculture are being developed.
As a result of the new conditions, to be a thoroughly-trained and competent agriculturist requires a special education, partly theoretical, partly practical. In many countries there are now agricultural schools or colleges supported by the State, and many such institutions exist in Britain. In Scotland, the Edinburgh chair of Rural Economy was founded in 1790; in Ireland, the Glasnevin Institution was inaugurated in 1838; and the establishment of the Royal Agricultural College, Cirencester, dates from 1845. In the United States nearly all the States have now colleges, or departments of colleges, devoted to the teaching of agriculture, and large allotments of public land have been made for their support. There are also numerous experimental stations. In Britain there has been a Board of Agriculture since 1889, under a cabinet minister, which was constituted a ministry in 1919; previously there was only a department under a committee of the Privy Council.
It is probable that on the whole the agriculture of Britain is farther advanced than that of any other region of similar size. Wheat, barley, and oats are the chief cereals in Britain; the chief roots are turnips and potatoes; other crops (besides grass and clover) are beans, peas, mangold, hops, and flax. In Europe at large the principal cereals are wheat, oats, barley, and rye, wheat being mostly grown in the middle and southern regions, such as France, Spain, part of Germany, Austria, Hungary, Italy, and southern Russia, the others in the more northern portion, while maize is grown in the warmest parts. Turnips are comparatively little grown out of Britain, beet-root in some sense taking their place; potatoes, however, are largely cultivated, except in the south. In the United States maize is the chief corn crop, next to which comes wheat, then oats; potatoes are an important crop, but turnips are only grown to a very small extent. In Canada large quantities of wheat are grown (more especially in Manitoba and the North-West), much is also now produced in the Australian colonies, in India, Argentina, &c.—Bibliography: W.

Their complexion is dark brown, approaching to black. They support themselves by hunting and fishing. There are numerous legends relating to the Ainos. According to one of these, of Japanese origin, they descended from the constellation of the Bear, whilst another mentions as their ancestor a certain Okikurumi who came down from heaven. The Ainos call themselves Ainu Utara, and the Chinese refer to them as the Tungi (barbarians of the East).

Air,the gaseous substance of which our atmosphere consists, being a mixture mainly of about 78 per cent by volume of nitrogen and 21 per cent of oxygen. The latter is absolutely essential to animal life, while the purpose chiefly served by the nitrogen appears to be to dilute the oxygen. Oxygen is more soluble in water than nitrogen, and hence the air dissolved in water contains about 10 per cent more oxygen than atmospheric air. The oxygen therefore available for those animals which breathe by gills is somewhat less diluted with nitrogen, but it is very much diluted with water. For the various properties and phenomena connected with air see such articles asAtmosphere,Aeronautics,Air-pump,Barometer,Combustion,Respiration, &c.
Air,in music (in It.aria), a continuous melody, in which some lyric subject or passion is expressed. The lyric melody of a single voice, accompanied by instruments, is its proper form of composition. Thus we find it in the higher order of musical works; as in cantatas, oratorios, operas, and also independently in concertos.—Airis also the name often given to the upper or most prominent part in a concerted piece, and is thus equivalent totreble,soprano, &c.
Aïr,orAsben. SeeAsben.
Aira.SeeHair-grass.
Air Beds and Cushions,often used by the sick and invalids, are composed of india-rubber or of cloth made air-tight by a solution of india-rubber, and when required for use filled with air, which thus supplies the place of the usual stuffing materials. They tend to prevent bed-sores from continuous lying in one position. They are also cheap and easily transported, as the bed or cushion, when not in use, can be packed in small compass, to be again inflated with air when wanted.
Air-bladder.SeeSwimming-bladder.
Air-brake,a brake operated by air pressure, usually applied to brake, simultaneously, all the wheels of a moving train. In the Westinghouse type, by means of an ingenious 'triple valve' carried one on each carriage, the train pipe is made to serve the dual purpose of supply and control. An air-pump on the engine compresses air into the main receiver, from which it flows through a reducing valve into the train pipe. The pressure, acting on the under side of the triple valve, moves the valve to its extremeposition, thereby opening a passage to an auxiliary receiver on the carriage and also putting the brake cylinder into communication with the atmosphere. A spring in the brake cylinder keeps the brakes in the 'off' position.
To apply the brakes, the pressure is lowered in the train pipe. The air pressure in the auxiliary receiver reverses the triple valve, thus admitting air to the brake cylinder and closing the outlet to atmosphere.
To remove the brakes, air from the main receiver is passed into the train pipe, and the triple valve is restored to the 'off' position. SeeTraction.—Bibliography: W. W. Wood,Westinghouse Air-brake; R. H. Blackhall,Air-brake Catechism.
Air-cells,cavities in the cellular tissue of the stems and leaves of plants which contain air only, the juices of the plants being contained in separate vessels. They are largest and most numerous in aquatic plants, as in theVallisneria spirālisand theVictoria regia, the gigantic leaves of which latter are buoyed up on the surface of the water by their means.—The minute cells in the lungs of animals are also called air-cells. There are also air-cells in the bodies of birds. They are connected with the respiratory system, and are situated in the cavity of the thorax and abdomen, and sometimes extend into the bones. They are most fully developed in birds of powerful and rapid flight, such as the albatross.
