In the summer a great accumulation of solar heat takes place on the dry surface soil, from which it cannot be released upwards by evaporation, as might be the case were the soil moist or covered with vegetation, nor can it be readily conveyed away downwards as happens on the ocean.
In illustration of the very slow diffusion of heat in the solid crust of the earth, and as affording a further indication of the climate of northern Asia, reference may here be made to the frozen soil of Siberia, in the vicinity of Yakutsk.
Under such conditions of the soil, the land, nevertheless, produces crops of wheat and other grain from fifteen to forty fold.
On the other hand Christianity, though Asiatic in its origin and essential ideas, has to a large extent taken its present form on European soil, and some of its most important manifestations - notably the Roman Church - are European reconstructions in which little of the Asiatic element remains.

They were bound to the soil and occupied holdings of scattered strips (amounting usually to a virgate or 30 acres) in return for a payment partly in labour and partly in kind.
The very laws which were made during successive reigns for protecting the tillers of the soil from spoil are the best proofs of the deplorable state of the husbandman."' In the r7th century those laws were made which paved the way for an improved system of agriculture in Scotland.
It Progress of agricul- is probable that very little improvement had taken ture from place, either in the cultivation of the soil or in the 1688 to management of live stock, from the Restoration down 1760.
Having arrived at the conclusion that the food of plants consists of minute particles of earth taken up by their rootlets, it followed that the more thoroughly the soil in which they grew was disintegrated, the more abundant would be the " pasture " (as he called it) to which their fibres would have access.
Such reliance did he place in the pulverization of the soil that he grew as many as thirteen crops of wheat on the same field without manure.
It is therefore necessary not only to pulverize the soil by repeated ploughings before it be seeded, but, as it becomes gradually more and more compressed afterwards, recourse must be had to tillage while the plants are growing; and this is hoeing, which also destroys the weeds that would deprive the plants of their nourishment.
The great future that seemed to await the application of steam power to the tillage of the soil proved illusory.
Barley, on the other hand, is sown in a lighter surface soil, and, with its short period for root-development, relies in a much greater degree on the stores of plant-food within the surface soil.
Accordingly it is more susceptible to exhaustion of surface soil as to its nitrogenous, and especially as to its mineral supplies; and in the common practice of agriculture it is found to be more benefited by direct mineral manures, especially phosphatic manures, than is wheat when sown under equal soil conditions.
The exhaustion of the soil induced by both barley and wheat is, however, characteristically that of available nitrogen; and when, under the ordinary conditions of manuring and cropping, artificial manure is still required, nitrogenous manures are, as a rule, necessary for both crops, and, for the spring-sown barley, superphosphate also.
Additional significance to the value of the above experiments on wheat and barley is afforded by the fact that the same series, with but slight modifications, has also been carried out since 1876 at the Woburn (Bedfordshire) experimental farm of the Royal Agricultural Society of England, the soil here being of light sandy character, and thus very different from the heavy soil of Rothamsted.
Independently of the necessary consideration of the general economy of the farm, the choice must be influenced partly by the character of the soil, but very much more by that of the climate.
The fact that the growth of a leguminous crop, such as red clover, leaves the soil in a higher condition for the subsequent growth of a grain crop - that, indeed, the growth of such a leguminous crop is to a great extent equivalent to the application of a nitrogenous manure for the cereal crop - was in effect known ages ago.
This has taken the form of inoculating the soil with the particular organism required by the particular kind of leguminous crop. To this end the endeavour has been made to produce preparations which shall contain in portable form the organisms required by the several plants, and though, as yet, it can hardly be claimed that they have been generally successful, the work done justifies hopes that the problem will eventually be solved in a practical direction.
The rotations extending to five, six, seven or more years are, in most cases, only adaptations of the principle to variations of soil, altitude, aspect, climate, markets and other local conditions.
As to the source of the nitrogen of the root-crops-the so-called " restorative crops "-these are as dependent as any crop that is grown on available nitrogen within the soil, which is generally supplied by the direct appli cation of nitrogenous manures, natural or artificial.
Under such conditions of supply, however, the root-crops, gross feeders as they are, and distributing a very large extent of fibrous feeding root within the soil, avail themselves of a much larger quantity of the nitrogen supplied than the cereal crops would do in similar circumstances.
This result is partly due to their period of accumulation and growth extending even months after the period of collection by the ripening cereals has terminated, and at the season when nitrification within the soil is most active, and the accumulation of nitrates in it is the greatest.
It is the leguminous fodder crops-especially clover, which has a much more extended period of growth, and much wider range of collection within the soil and subsoil, than any of the other crops of the rotation-that yield in their produce the largest amount of nitrogen per acre.
For root-feeders, bisulphide of carbon injected into the soil is of particular value.
The dipterous garden pests, such as the onion fly, carrot fly and celery fly, can best be kept in check by the use of paraffin emulsions and the treatment of the soil with gas-lime after the crop is lifted.
It may mean what is ordinarily understood by the word - climate, rainfall, railway rates or anything else except " indestructible powers of the soil."
It everywhere shows a preference for a moist but well-drained soil, and never attains its full stature or luxuriance of growth upon arid ground, whether on plain or mountain - a peculiarity that should be remembered by the planter.
In a favourable soil and open situation it becomes the tallest and one of the stateliest of European trees, rising sometimes to a height of from 150 to 170 ft., the trunk attaining a diameter of from 5 to 6 ft.
In its native habitats it is said to endure for several centuries; but in those countries from which the commercial supply of its timber is chiefly drawn, it attains perfection in from 70 to 90 years, according to soil and situation.
This species prefers a peaty soil, and often grows luxuriantly in very moist situations.
It was introduced into Britain soon after its rediscovery by David Douglas in 1827, and has been widely planted, but does not flourish well where exposed to high winds or in too shallow soil.

In command of the Greek contingent from Phylace in Thessaly, he was the first to spring ashore on Trojan soil, although he knew it meant instant death.
Camden, about the end of the 17th century, wrote that "the people are very industrious, so that though the soil about it be barren and improfitable, not fit to live on, they have so flourished..
The substratum of the plain is a bed of boulders, covered during the lapse of ages by a deposit of rich alluvial soil.
The soil is an oozy mud which can only be made capable of carrying buildings by the artificial means of pile-driving; there is no land fit for agriculture or the rearing of cattle; the sole food supply is fish from the lagoon, and there is no drinking-water save such as could be stored from the rainfall.
In the other parts of the state the soil is composed mainly of glacial drift, and is generally deep and fertile.
The soil is almost throughout "black earth," and Podolia is one of the most fertile governments of Russia.
The soil is composed of red ferruginous kankar, with a stratum of clay in the more elevated parts, covered by a thin layer of vegetable mould, or by recent alluvial deposits.
Towards the city the red soil is intersected by creeks and morasses, whose margins yield crops of rice, mustard and til seed; while to the east of the town, a broad, alluvial, well-cultivated plain reaches as far as the junction of the Dhaleswari and Lakshmia rivers.
It consists entirely of rich alluvial soil, annually inundated to a depth varying from 2 to 14 ft.
In both there are species which form no nest or burrow, others which construct a simple silk-lined tunnel in the soil, and others which close the aperture of the burrow with a hinged door; while both share the habit of lining the burrow with silk to prevent the infall of loose sand or mould; and the species which make an open burrow close the aperture with a sheet of silk in the winter during hibernation and open it again in the spring.
Quite commonly the burrow has a second passage running obliquely upwards from the main passage to the surface of the soil, and this subsidiary track may itself be shut off from the main branch by an inner door, so that when an enemy has forced an entrance through the main door, the spider retreats behind the second, leaving the intruder to explore the seemingly empty burrow.
Species of other families (Lycosidae, Clubionidae) may live for a few seasons, hibernating in the soil or amongst dead leaves; and examples of the larger spiders (Aviculariidae) have been kept alive in captivity for several years.
In regions where climatic conditions are favourable, cotton grows more or less successfully on almost all kinds of soil; it can be grown on light sandy soils, loams, heavy clays and sandy " bottom " lands with varying success.
The soil should be able to maintain very uniform conditions of moisture.
The best soil for cotton is thus a deep, welldrained loam, able to afford a uniform supply of moisture during the growing period.
The result is a great destruction of the humus of the soil, and great leaching and washing, especially in the light loams of the hill country of the United States.
In the moist bottom-lands along the rivers it is the custom to throw the soil up in high beds with the plough, and then to cultivate them deep. This is the more common method of drainage, but it is expensive, as it has to be renewed every few years.
There can be no question that a deep soil is better for the cottonplant; but the expense of obtaining it, the risk of injuring the soil through leaching, and the danger of bringing poor soil to the surface, have led many planters to oppose this plan.
It is believed that the rotation must differ with every variety of soil, with the result that each planter has his own method, and little can be said in general.
A more careful study of the physical as well as the chemical properties of a soil must precede intelligent experimentation in rotation.
The exhaustion of the soil under cotton culture is chiefly due to the loss of humus, and nature soon puts this back in the excellent climate of the cotton-growing belt.
The fibre takes almost nothing from the land, and where the seeds are restored to the soil in some form, even without other fertilizers, the exhaustion of the soil is very slow.
If the burningup of humus and the leaching of the soil could be prevented, there is no reason whyia cotton soil should not produce good crops continuously for an indefinite time.
A narrow deep furrow is usually run immediately in advance of the planter, to break up the soil under the seed.
It has frequently been noted that even well-fertilized plants upon good soil will mature only 15 or 20% of the bolls produced.
The delta soil is typically a heavy, black, alluvial clay, very fertile, but difficult to work; admixture of sand is beneficial, and the localities where this occurs yield the best cotton.
A more rational proceeding would be to feed the meal to animals and apply the resulting manure to the soil.
The roots are prevented from fulfilling their function of taking up water and salts from the soil; the leaves accordingly droop, and the whole plant wilts and in bad attacks dies.
Cyprus has a soil and climate suited to cotton, which was formerly grown here on a large scale.
The cultivation of cotton on a commercial scale is quite new in Nyasaland, and although general conditions of soil and climate appear favourable the question of transport is serious and labour is not abundant.
Possessing soil, climate and apparently all the requisite elements from nature for the production of cotton to an almost boundless extent, and of a 1 Approximately.
The great plain in Sheng-king is in many parts swampy, and in the neighbourhood of the sea, where the soil emits a saline exudation such as is also common in the north of China, it is perfectly sterile.
It is noticeable that it was on French soil that the seed had been sown.3 Preached on French soil by a pope of French descent, the Crusades began - and they continued - as essentially a French (or perhaps better Norman-French) enterprise; and the kingdom which they established in the East was essentially a French kingdom, in its speech and its customs, its virtues and its vices.
The tables were turned; and fighting on their own soil for the recovery of what was to them too a holy place, the Mahommedans easily carried the day.
The Crusade had failed - failed because a leaderless army, torn by political dissensions and fighting on a foreign soil, could not succeed against forces united by religious zeal under the banner of a leader like Saladin.

Owing to the configuration of the soil, the climate of Moravia varies more than might be expected in so small an area, so that, while the vine and maize are cultivated successfully in the southern plains, the weather in the mountainous districts is somewhat rigorous.
The Cephisus, rising in Pentelicus, enters the sea at New Phalerum; in summer it dwindles to an insignificant stream, while the Ilissus, descending from Hymettus, is totally dry, probably owing to the destruction of the ancient forests on both mountains, and the consequent denudation of the soil.
The Attic plain, notwithstanding the lightness of the soil, furnished an adequate supply of cereals; olive and fig groves and vineyards were cultivated from the earliest times in the valley of the Cephisus, and pasturage for sheep and goats was abundant.
This accords with the cherished tradition which made the Athenians children of the soil, and free from admixture with conquering tribes.

Close to the coast the soil is for the most part a coral sand.
On the foothills and in the less rugged mountain districts there is a thin but rich clay soil derived from coral limestone.
Mole-rats are easily recognized by the peculiarly flattened head, in which the minute eyes are covered with skin, the wart-like ears, and rudimentary tail; they make burrows in sandy soil, and feed on bulbs and roots.
East of the town rises Mayon, an active volcano, and the rich volcanic soil in this region produces hemp, rice and coco-nuts.
The soil is a clayey or a sandy loam, and very fertile except in the Usar tracts, where there is a saline efflorescence.
It contains all the best land in Berar; it is full of deep, rich, black alluvial soil, of almost inexhaustible fertility, and it undulates sufficiently to maintain a natural system of drainage, but there is nothing picturesque about this broad strip of champaign country.
In this region the sandstone rocks are generally overlaid with heavy black soil formed from the decaying trap, which is principally devoted to the cultivation of the spring crops, wheat and grain, while rice and hill millets are sown in the lighter and more sandy soils.
The surface soil of Berar is to a great extent a rich black vegetable mould; and where this surface soil does not exist, there are muram and trap with a shallow upper crust of inferior light soil.
The Nagpur country, drained by the Wardha and Wainganga rivers, contains towards the west the shallow black soil in which autumn crops like cotton and the large millet, juar, which do not require excessive moisture, can be successfully cultivated.

At first sight few natural materials appear to be of less interest than the soil; yet its importance is manifest on the slightest reflection.
It is often of very mixed origin, being derived from the detritus of many kinds of rocks, and usually forms soil of a fertile character.
The good or bad qualities of a soil have reference to the needs of the crops which are to be grown upon it, and it is only after a consideration of the requirements of plants that a clear conception can be formed of what characters the soil must possess for it to be a suitable medium on which healthy crops can be raised.
In the first place, soil, to be of any use, must be sufficiently loose and porous to allow the roots of plants to grow and extend freely.
If the soil holds too much it becomes water-logged and its temperature falls below the point for healthy growth, at any rate of the kinds of plants.
In addition, the temperature of the soil largely controls the yield of crops which can be obtained from the land.
Soil whose temperature remains low, whether from its northerly aspect or from its high water content or other cause, is unsatisfactory, because the germination of seeds and the general life processes of plants cannot go on satisfactorily except at certain temperatures well above freezing-point.
A good soil should be deep to allow of extensive root development and, in the case of arable soils, easy to work with implements.
An examination of the soil shows it to be composed of a vast number of small particles of sand, clay, chalk and humus, in which are generally imbedded larger or smaller stones.
When a little soil is shaken up with water in a tumbler the sand particles rapidly fall to the bottom and form a layer which resembles ordinary sand of the seashore or river banks.
A soil consisting of sand entirely would be very loose, would have little capacity to retain water, would be liable to become very hot in the daytime and cool at night and would be quite unsuitable for growth of plants.
It is obvious, therefore, that soil composed entirely of clay is as useless as pure sand so far as the growth of crops upon it is concerned.
Humus, the remaining constituent of soil, is the term used for the decaying vegetable and animal matter in the soil.
Few of the commonly cultivated crops can live in a soil consisting mainly of humus.
From the above account it will be understood that not one of the four chief soil constituents is in itself of value for the growth of crops, yet when they are mixed, as they usually are in the soils met with in nature, one corrects the deficiencies of the other.
A perfect soil would be such a blend of sand, clay, chalk and humus as would contain sufficient clay and humus to prevent drought, enough sand to render it pervious to fresh air and prevent waterlogging, chalk enough to correct the tendency to acidity of the humus present, and would have within it various substances which would serve as food-materials to the crops.
In the mechanical analysis of the soil, after separation of the stones and fine gravel by means of sieves, the remainder of the finer earth is subjected to various processes of sifting and deposition from water with a view of determining the relative proportions of sand, silt and clay present in it.
It is generally from 30 to 50% of the total volume occupied by the soil.
Where the soil grains are quite free from each other the smaller grains tend to fill up the spaces between the larger ones; hence it might be concluded that in clays the amount of pore-space would be less than in coarser sands.
With the exception of the carbon and a small proportion of the oxygen and nitrogen, which may be partially derived from the air, these elements are taken from the soil by crops.
Leguminous crops take some of the nitrogen which they require from the air, but most plants obtain it from the nitrates present in the soil.
