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.

AUTUMN

Autumn is the season between summer and winter, in the northern hemisphere traditionally regarded as embracing August, September, and October, or three months about that time. The beginning of the astronomical autumn is September the 22nd, the autumnal equinox; and the end is December the 21st, the shortest day. The autumn of the southern hemisphere takes place at the time of the northern spring.

BRITISH SUMMER TIME

British Summer Time is a British daylight saving scheme which resulted from the Summer-Time Act enacted by Parliament and adopted in 1916, whereby on a specified date in spring the official time is advanced one hour ahead of Greenwich mean time which is restored on a specified date in autumn. A bill to provide for a fixed period - the night of the last Saturday in March until the night of the first Sunday in October - was introduced in Parliament in 1922 so as to synchronise the summer times of Britain, France and Belgium.

BUDDING

Budding is the art of multiplying plants by causing the leaf-bud of one species or variety to grow upon the branch of another. The operation consists in shaving off a leaf-bud, with a portion of the wood beneath it, which portion is afterwards removed by a sudden jerk of the operator's finger and thumb, aided by the budding-knife. An incision in the bark of the stock is then made in the form of a T; the two side lips are pushed aside, the bud is thrust between the bark and the wood, the upper end of its bark is cut to a level with the cross arm of the T, and the whole is bound up with worsted or other soft fastening, the point of the bud being left exposed.

In performing the operation, a knife with a thin flat handle and a blade with a peculiar edge is required. The bud must be fully formed; the bark of the stock must separate readily from the wood below it; and young branches should always be chosen, as having beneath the bark the largest quantity of cambium or viscid matter out of which tissue is formed. The maturer shoots of the year in which the operation is performed are the best. The autumn is the best time for budding, though it may also be practised in the spring.

CALENDAR

A calendar (named from the Latin calendarium, from calendce, the first day of the month), is a record or marking out of time as systematically divided into years, months, weeks, and days.

The periodical occurrence of certain natural phenomena gave rise to the first division of time, the division into weeks being the only purely arbitrary partition. The year of the ancient Egyptians was based on the changes of the seasons alone, without reference to the lunar month, and contained 365 days divided into twelve months of thirty days each, with five supplementary days at the end of the year.

The Jewish year consisted of lunar months of which they reckoned twelve in the year, intercalating a thirteenth when necessary to maintain the correspondence of the particular months with the regular recurrence of the seasons.

The Greeks in the earliest period also reckoned by lunar and intercalary months, but after one or two changes adopted the plan of Meton and Euctemon, who took account of the fact that in a period of nineteen years, the new moons return upon the same days of the year as before. This period of nineteen years was found, however, to be about six hours too long, and subsequent calculators still failed to make the beginning of the seasons return on the same fixed day of the year. Each month was divided into three decads.

The Romans at first divided the year into ten months, but they early adopted the Greek method of lunar and intercalary months, making the lunar year consist of 354, and afterwards of 355 days, leaving ten or eleven days and a fraction to be supplied by the intercalary division. This arrangement continued until the time of Julius Caesar. The first day of the month was called the calends. In March, May, July, and October the 15th, in other months the 13th, was called the ides. The ninth day before the ides (reckoning inclusive) was called the nones, being therefore either the 7th or the 5th of the month. From the inaccuracy of the Roman method of reckoning the calendar came to represent the vernal equinox nearly two months after the event, and at the request of Julius Caesar, the Greek astronomer Sosigenes with the assistance of Marcus Fabius, contrived the so-called Julian calendar. The chief improvement consisted in restoring the equinox to its proper place by inserting two months between November and December, so that the year 707 (46 BC), called the year of confusion, contained fourteen months.

In the number of days the Greek computation was adopted, which made it 365.25. To dispose of the quarter of a day it was determined to intercalate a day every fourth year between the 23rd and 24th of February. This calendar continued in use among the Romans until the fall of the empire, and throughout Christendom until 1582.

By this time, owing to the cumulative error of eleven minutes, the vernal equinox really took place ten days earlier than its date in the calendar, and accordingly Pope Gregory XIII issued a brief abolishing the Julian calendar in all Catholic countries, and introducing in its stead the one now in use, the Gregorian or reformed calendar. In this way began the new style, as opposed to the other or old style. Ten days were to be dropped; every hundredth year, which by the old style was to have been a leap year, was now to be a common year, the fourth excepted; and the length of the solar year was taken to be 365 days, five hours, forty-nine minutes, and twelve seconds, the difference between which and subsequent observations is immaterial. The new calendar was adopted in Spain, Portugal, and France in 1582; in Catholic Switzerland, Germany and the Netherlands in 1583; in Poland in 1586; in Hungary in 1587; in Protestant Germany, Holland, and Denmark in 1700; in Switzerland in 1701; in England in 1752; and in Sweden, 1753.

In the English calendar of 1752, also, the 1st of January was now adopted as the beginning of the legal year, and it was customary for some time to give two dates for the period intervening between 1st January and 25th March, that of the old and that of the new year, as January 1752/3. Russia alone retained the old style, which by 1906 differed twelve days from the new.

In France, during the revolution, a new calendar was introduced by a decree of the rational Convention, on November the 24th, 1793. The time from which the new reckoning was to commence was the autumnal equinox of 1792, which fell upon the 22nd of September, when the first decree of the new republic had been promulgated. The year was made to consist of twelve months of three decades each, and, to complete the full number, five fete days, or sansculotides (in leap years six) were added to the end of the year. The seasons and months were as follows: Autumn; 22nd September to 22nd December Vendimiaire, vintage month; Brumaire, foggy month; Frimaire, sleet month. Winter; 22nd December to 22nd March: Nivose, snowy month; Plumose, rainy month; Ventose, windy month. Spring; 22nd March to 22nd June: Germinal, bud month; Floreal, flower month; Prairial, meadow month. Summer; 22nd June to 22nd Sept.: Messidor, harvest month; Thermidor, hot month; Fructidor, fruit month. The common Christian or Gregorian calendar was re-established in France on the 1st of January, 1806, by Napoleon.

COMET

Some comets are only visible by the aid of the telescope, while others can be seen by the naked eye. In the latter case they usually appear like stars accompanied with a train of light, sometimes short and sometimes extending over half the sky, mostly single and more or less curved, but sometimes forked. In a comet which appeared in 1744 the train was divided into several branches, spreading out from the head like a fan. The train is not stationary relatively to the head, but is subject to remarkable movements. The direction in which it points is always opposite to the sun, and as the , comet passes its perihelion the train changes its apparent position with extraordinary velocity. The head of the comet is itself of different degrees of luminosity, there being usually a central core, called the nucleus, of greater brilliancy than the surrounding envelope, called the coma.

Comets were long regarded as supernatural objects, and usually as portents of impending calamity. Tycho Brahe was the first who expressed a rational opinion on the subject, coming to the conclusion that the comet of 1577 was a heavenly body at a greater distance from the earth than that of the moon. The general law of the motion of bodies, as well as his own observations on the comet of 1680, led Isaac Newton to conclude that the orbits of the comets must, like those of the planets, be ellipses, having the sun in one focus, but far more eccentric; and having their aphelions, or greater distances from the sun, far remote in the regions of space.

This idea was taken up by Halley, who collated the observations which had been made of all the twenty-four comets of which notice had been taken previous to 1680. The results were very interesting. With but few exceptions the comets had passed within less than the earth's shortest distance from the sun, some of them within less than one-third of it, and the average about one-half. Out of the number, too, nearly two-thirds had had their motions retrograde, or moved in the opposite direction to the planets. While Halley was engaged on these comparisons and deductions the comet of 1682 made its appearance, and he found that there was a wonderful resemblance between it and three other comets that he found recorded - the comets of 1456, of 1531, and of 1607. The times of the appearance of these comets had been at very nearly regular intervals, the average period being between seventy-five and seventy-six years. Their distances from the sun, when in perihelion, or when nearest to that luminary, had been nearly the same, being nearly six-tenths of that of the earth, and not varying more than one-sixtieth from each other.

The inclination of their orbits to that of the earth had also been nearly the same, between 17 degrees and 18 degrees; and their motions had all been retrograde. Putting these facts together, Halley concluded that the comets of 1456, 1531,1607, and 1682 were reappearances of one and the same comet, which revolved in an elliptic orbit round the sun, performing its circuit in a period varying from a little more than seventy-six years to a little less than seventy-five; or having, as far as the observations had been carried, a variation of about fifteen months in the absolute duration of its year, measured according to that of the earth. For this variation in the time of its revolution Halley accounted upon the supposition that the form of its orbit had been altered by the attraction of the remote planets Jupiter and Saturn as it passed near to them; and thence he concluded that the period of its next appearance would be lengthened, but that it would certainly reappear in 1758 or early in 1759. As the time of its expected reappearance approached, Clairaut calculated that it would be retarded 100 days by the attraction of Saturn, and 518 by that of Jupiter, so that it would not come to the perihelion, or point of its orbit nearest the 500 sun, until the 13th of April, 1759.

It actually reached its perihelion on the 13th of March, 1759, being thirty days earlier than he had calculated. Along with the period of this comet and its perihelion distance, the magnitude and form of its path were also calculated. Estimating the mean distance of the earth from the sun at 95,000,000 miles (the number which was at that time considered as the true one), the mean distance of the comet was calculated to be 1,705,250,000 miles; its greatest distance from the sun, 3,355,400,000; its least distance, 55,100,000; and the transverse or largest diameter of its orbit, 3,410,500,000. This comet, therefore, is a body belonging to the solar system, and quite beyond the attraction of any body which does not belong to that system; and as this is determined of one comet, analogy points it out as being the case with them all. In 1835 it again returned, being first seen at Rome, on August the 5th, and from that time continued to be observed until the end of the year in Europe, and through a great part of spring 1836 in the southern hemisphere.

The comet denominated Encke's comet, which has made repeated appearances, was first observed in 1818, and was identified with a comet observed in 1786, also with a comet discovered in 1795 by Miss Herschel in the constellation Cygnus, and with another seen in 1805. Its orbit is an ellipse of comparatively small dimensions, wholly within the orbit of Jupiter; its period is 1260 days, or about three years and three-tenths. It has been frequently observed since.

Another comet, the history of which is of the utmost importance in the latest theories regarding the connection of these bodies and the periodic showers of shooting-stars, is one known as Biela's comet, discovered in 1826. It revolved about the sun in about 6.75 years, and was identified as the same comet which was observed in 1772 and in 1806. Its returns were noted in 1832, 1839, and 1845. In 1846 it divided into two, returned double in 1852, but has not since been seen, the Supposition being that it has been dissipated, and that it was represented by a great shower of meteors that were seen in November 1872. One of the most remarkable comets of recent times was that known as Donati's, discovered by Dr. Donati of Florence in 1858. It was very brilliant in England in the autumn of that year, and on the 18th of October was near coming into collision with Venus, The year 1881 was remarkable for the number of comets recorded. During that year no fewer than seven comets, including the well-known short-period comet Encke's, were observed.

FALLOW

Fallow is land left unsown for a period of time, usually a year in order that it may recover itself from an exhausted state. Strictly spealdng, fallow ground is left altogether without crops; but in agricultural usage strict fallow is not always adopted, and the term fallow is applied to various modes of treatment, of which at least three distinct varieties are recognized: baref allow, bastard fallow, and green-crop fallow. Bare fallow is that in which the land remains completely bare for a whole year; in bastard fallow it is ploughed up and worked after the removal of a spring or summer crop, preparatory to the sowing of a root or forage crop, to occupy the ground during autumn or winter; in green-crop fallow the land is sown with a root-crop, such as turnips or potatoes, placed in rows far enough apart to admit of the intermediate spaces being stirred, pulverized, and cleaned, during its growth, by machine or hand implements.

Fallowing is an ancient process, it has been known for centuries that the same crop frown on the same land deteriorates after a few years, partly because the soil is exhausted and partly because of disease. By leaving the land for a year, it can recover and subsequent crops improve.

FROST

Frost is the name given to the state of the weather when the temperature is below the freezing-point of water. The intensity of the cold in frost is conveniently indicated by the popular expression so many degrees of frost, which means that the temperature of the atmosphere is so many degrees below the point at which the freezing of water commences.

Frost is often very destructive to vegetation, owing to the fact that water, which is generally the chief constituent of the juices of plants, expands when freezing, and bursts, and thus destroys, the vesicles of the plant. In the same way rain-water, freezing in the crevices of rocks and roads, breaks up their surfaces, and often detaches large fragments.

Hoar-frost is frozen dew. It may either freeze while it is falling, when it is found loosely scattered on the ground; or being deposited as dew in the early part of the night it may freeze during a subsequent part of it, owing to radiation. It is generally seen most profusely in spring and autumn; because at those times, while on clear nights the cold is sufficient to freeze the dew, the days are at the same time sufficiently warm to cause a very considerable quantity of moisture to evaporate into the air.

MOUNTAIN MEADOW MASSACRE

The Mountain Meadow Massacre occurred in the autumn of 1857 when a body of thirty-six Arkansas and Missouri emigrants en route to California, were brutally murdered at Mountain Meadow, Utah, by a band of Indians, who were incited thereto by Lee, a Mormon fanatic. It was the period of the first troubles between the United States Government and the Mormons. Brigham Young had made threats of turning the Indians loose upon west-bound emigrants, but the Mormons, as a body, were innocent of the massacre. The emigrant party was encamped at Mountain Meadow when the attack began on September the 7th. They threw up earthworks and defended themselves for four days. Lee, under pretence of friendship, succeeded in drawing them out and murdering the whole party.

SPRING

Spring is the first season of the year. In the northern hemisphere it is reckoned astronomically from the vernal equinox (about March the 21st) until the summer solstice (about June the 21st). In the southern hemisphere spring corresponds in date with the northern autumn.
