From this oppressive feeling he found relief in the thought set forth in the opening of the second book of his Political Economy - that, while the conditions of production have the necessity of physical laws, the distribution of what is produced among the various classes of producers is a matter of human arrangement, dependent upon alterable customs and institutions.

The manor was indeed self-sufficient and independent in the sense that it could furnish everything required by the majority of the inhabitants, and that over the greater part of rural England production was not carried on with a view to a distant market.

The difference between schists and gneisses is mainly that the latter have less highly developed foliation; they also, as a rule, are more coarse grained, and contain far more quartz and felspar, two minerals which rarely assume platy or acicular forms, and hence do not lead to the production of a fissile character in the rocks in which they are important constituents.

The development of foliation in shaly rocks is undoubtedly closely akin to the production of cleavage in slates.

Flowering and fruiting go on continually, although in diminishing degree, until the advent of frost, which kills the flowers and young bolls and so puts an end to the production of cotton for the season.

In the tropics the essential requirements are very similar, but there the dry season checks production in much the same way as do the frosts in temperate climates.

Cotton-picking is at once the most difficult and most expensive operation in cotton production.

It has been commonly thought that the production of cotton in the south is limited by the amount that can be picked, but this limit is evidently very remote.

In modern commercial cotton production ginning machines are always used.

Some of the American ginners are very large indeed, a number (Bulletin of the Bureau of the Census on Cotton Production) being reported as containing on the average 1 156 saws with an average production of 4120 bales of cotton.

There are no figures obtainable as to the production, but it must be very large, considering that the crop provides clothing for a large proportion of the population of China.

The production is not sufficient to meet the home demand; during the five years of normal trade before the war with Russia Japan imported annually about 800,000 bales of cotton, chiefly from British India, China and the United States, and during the same period exported each year some 2000 bales, mainly to Korea.

On the completion of drilling, or when the production is found to decrease, it is usual to torpedo the well to increase the flow.

It must be borne in mind that although the explosion may increase the production for a time, it is by no means certain that the actual output of a well is increased in all such cases, though from some wells there would be no production without the use of the torpedo.

The operation was, however, completely revolutionized in the United States by the introduction of the " cracking process," and by the division of the distillation into two parts, one consisting in the removal of the more volatile constituents of the oil, and the other in the distillation (which is usually conducted in separate stills) of the residues from the first distillation, for the production of lubricating oils and paraffin.

Tobacco culture, which declined after 1860 on account of the competition of Cuba and Sumatra, has revived since 1885 through the introduction of Cuban and Sumatran seed; the product of 1907 (6,937,500 lb) was more than six times that of 1899, the product in 1899 (1,125,600 lb) being more than twice that of 1889 (470,443 lb), which in turn was more than twenty times that for 1880 (21,182 lb)-the smallest production recorded for many decades.

The sweet potato and pea-nut crops have also become very valuable; on the other hand the Census of 1900 showed a decline in acreage and production of cotton.

Most of the tobacco used is imported from Cuba, though, as has been indicated, the production of the state has greatly increased since 1880.

About the beginning of the 10th century, however, the view was promulgated that the spontaneous production of helium from radium may be an instance of the transformation of one element into another.

Cereals, forage crops, vegetables and fruits of the cold temperate zone can be produced easily, but distance from markets and lack of transport have restricted their production to local needs.

His programme included the collective ownership of the means of production and the international association of labour, but when in June 1899 he entered Waldeck-Rousseau's cabinet of "republican defence" as minister of commerce he limited himself to practical reforms, devoting his attention to the improvement of the mercantile marine, to the development of trade, of technical education, of the postal system, and to the amelioration of the conditions of labour.

An alkali or base is a substance which neutralizes an acid with the production of salts but with no evolution of hydrogen.

Thus, in the production of hydrochloric acid from hydrogen and chlorine 22,000 calories are developed; in the production of hydrobromic acid from hydrogen and bromine, however, only 8440 caloriesare developed; and in the formation of hydriodic acid from hydrogen and iodine 6040 calories are absorbed.

Lastly, in the production of gaseous hydriodic acid from hydrogen and solid iodine H2 - 1 - 12=HI+HI, so much energy is expended in the decomposition of the hydrogen and iodine molecules and in the conversion of the iodine into the gaseous condition, that the heat which it may be supposed is developed by the combination of the hydrogen and iodine atoms is insufficient to balance the expenditure, and the final result is therefore negative; hence it is necessary in forming hydriodic acid from its elements to apply heat continuously.

Tantalum has in recent years been turned to economic service, being employed, in the same manner as tungsten, for the production of the filaments employed in incandescent electric lighting.

Hitherto we have generally restricted ourselves to syntheses which result in the production of a true benzene ring; but there are many reactions by which reduced benzene rings are synthesized, and from the compounds so obtained true benzenoid compounds may be prepared.

If we accept Kekule's formula for the benzene nucleus, then we may expect the double linkages to be opened up partially, either by oxidation or reduction, with the formation of di-, tetra-, or hexa-hydro derivatives, or entirely, with the production of open chain compounds.

It is remarkable that sulphur can replace two methine or CH groups with the production of compounds greatly resembling the original one.

Similarly a CH group may be replaced by a nitrogen atom with the production of compounds of similar stability; thus benzene gives pyridine, naphthalene gives quinoline and isoquinoline; anthracene gives acridine and a and 3 anthrapyridines.

Most of the simple ring systems which contain two adjacent carbon atoms may suffer fusion with any other ring (also containing two adjacent carbon atoms) with the production of nuclei of greater complexity.

Mention may be made of the phenomenon of halochromism, the name given to the power of colourless or faintly-coloured substances of combining with acids to form highly-coloured substances without the necessary production of a chromophoric group. The researches of Adolf von Baeyer and Villiger, Kehrmann, Kauffmann and others, show that this property is possessed by very many and varied substances.

This theory explains the fluorescence of anthranilic acid (o-aminobenzoic acid), by regarding the aniline residue as the luminophore, and the carboxyl group as the fluorogen, since, apparently, the introduction of the latter into the non-fluorescent aniline molecule involves the production of a fluorescent substance.

His first music master was Gottlieb Muller, who thought him self-willed and eccentric; and his first production as a composer was an overture, performed at the Leipzig theatre in 1830.

In 1814 Tassaert observed the spontaneous formation of a blue compound, very similar to ultramarine, if not identical with it, in a soda-furnace at St Gobain, which caused the Societe pour l'Encouragement d'Industrie to offer, in 1824, a prize for the artificial production of the precious colour.

The two parts are distinguished by difference of style; the Hebrew principle of parallelism of clauses is employed far more in the first than in the second, which has a number of plain prose passages, and is also rich in uncommon compound terms. In view of these differences there is ground for holding that the second part is a separate production which has been united with the first by an editor, an historical haggadic sketch, a midrash, full of imaginative additions to the Biblical narrative, and enlivened by many striking ethical reflections.

The style shows that the book was written in Greek, though naturally it contains Hebraisms. The author of the first part was in all probability an Alexandrian Jew; nothing further is known of him; and this is true of the author of the second part, if that be a separate production.

This gave rise to a production of sulphuretted hydrogen which is found in the deposits, as well as in the deeper waters.

Orchard fruits are fairly varied, but, compared with other states, unimportant; and the production of small fruits is comparatively small, the largest crop being strawberries.

The production of the island from 1850 to 1868 averaged 469,934 tons yearly, rising from 223,145 to 749,000; from 1869 to 1886 (continuing high during the period of the Ten Years' War), 632,003 tons; from 1887 to 1907 - omitting the five years 1896-1900 when the industry was prostrated by war,-909,827 tons (and including the war period, 758,066); and in the six harvests of 1901-1906, 1,016,899 tons.

We find in them the same beauties and the same defects that we observe in the production of the Iranian authors.

Appended to the Paedagogue are two hymns, which are, in all probability, the production of Clement, though some have conjectured that they were portions of the church service of that time.

His last production was Christ admonishing Martha.

It supports a fishing population of over 30,000, most of whom are Annamese; the fish, which are taken by means of large nets at the end of the inundation, are either dried or fermented for the production of the sauce known as nuoc-mam.

The history of the peach almond and nectarine is interesting and important as regards the question of the origin of species and the production and perpetuation of varieties.

Minnesota ranked third among the states of the Union in 1900 in the production of lumber, but in 1905 was fifth, the supply having diminished and the industry having been developed in the states of Washington and Louisiana.

Minnesota ranked first among the states in 1902 in the production of iron ore.

These facts of distribution are due to certain conditions that govern the production of organic substance in the oceans.

It follows, too, that when there is a number of substances, all essential for the elaboration of living material, and when one of these is present in minimal proportion, that one substance rules the production, just as the effective strength of a chain depends on the weakest link.

Following the great spring production of plant substance there is, therefore, a summer outburst of animal life.

Among the chief industries are those for the production of articles of food and drink.

An enormous development of agricultural resources has taken place within the Brahmaputra basin of late years, chiefly in the direction of tea cultivation, as well as in the production of jute and silk.

In accordance with the principles of energetics, any change which involves a decrease in the total available energy of the system will tend to occur, and thus the necessary and sufficient condition for the production of electromotive force is that the available energy of the system should decrease when the current flows.

In Africa it seems probable that the production of rubber from vines is likely to be entirely superseded in process of time, and replaced by the plantations of trees which are already being established in those districts in which careful experiment has determined the kind of rubber tree best adapted to the locality.

Although the cost of transport from the remote forest regions of some districts is a serious consideration, this is not likely to be operative in reducing production until there has been a considerable and permanent fall in price, by which time new areas in those countries in which planting is now taking place will probably have come into bearing.

In 1909 the total production of rubber is stated to have been about 70,000 tons, of which more than one-half came from tropical America, about one-third from Africa, whilst the remainder was chiefly of Asiatic origin, including " plantation " rubber from Ceylon and Malaya, which amounted to about 3000 tons.

Each year should therefore show an increase in the production of plantation rubber.

No trustworthy estimate of the rate of the increase of production can, however, be formed, as several uncertain economic factors have to be taken into account.

Among these are the precise extent of demand, the limit of the inevitable fall in price with largely increased production, the cost of labour as increasing amounts are required, and the effect of changed conditions on the output of " wild " rubber and the competition of the new plantations which are being established in tropical America.

Difficulties in the supply of labour in the East may hinder the further development of the rubber-planting industry, especially at a period when a reduction in the cost of production may be the chief problem.

During 1909, without any serious decline in production, the price rapidly rose, owing to extraordinary causes, to about ios.

Having regard to the present cost of producing " plantation " rubber, and to the probability that, apart from a possible increase in the price of labour, this cost is susceptible of further reduction, it may be concluded that rubber production will continue to be profitable even should a considerable fall in market value take place.

The yield of latex is at first small, but increases with successive tappings, which appear to stimulate the local production of latex, and finally reaches a maximum.

Too frequent tapping leads to the production of latex poor in caoutchouc, whilst tapping of trees before they are six or seven years old, and from 20-25 in.

The cost of production may be assumed to be about is.

It is, however, important to remember that rough as these native methods are they result in the production of rubber which commands the highest price.

The probabilities are that in the end the production of a rubber as nearly as possible free from water and impurities and of constant composition will be realized as best meeting the requirements of the modern manufacturer.

In the present transition stage of rubber production it is necessary for the manufacturer in Europe to wash all rubber.

In connexion with the production of rubber the most important factor is the proportion of caoutchouc it contains.

The presence of more than a small percentage of resin in the latex leads to the production of rubber containing much resin, which seriously depreciates its commercial value for most purposes.

Sulphur when warmed with caoutchouc combines with it, and on this fact the vulcanization of rubber depends, and also the production, with an excess of sulphur, of the hard black material known as vulcanite or ebonite.

Rubber slowly absorbs oxygen when exposed to air and light, the absorption of oxygen being accompanied by a gradual change in the characteristic properties of rubber, and ultimately to the production of a hard, inelastic, brittle substance containing oxygen.

The harsher measures which about that time began to be adopted towards his co-religionists in France are usually assigned as the motive of this step. He now devoted himself during six years to the production of lenses of enormous focal distance, which, mounted on high poles, and connected with the eye-piece by means of a cord, formed what were called "aerial telescopes."

Germany, Austria, Hungary, France, Russia and the United States began to rank as producers during the second and third decades; Belgium entered in about 1840; Italy in the 'sixties; Mexico, Canada, Japan and Greece in the 'eighties; while Australia assumed importance in 1888 with a production of about 18,000 tons, although it had contributed small and varying amounts for many preceding decades.

Since this date, it has, on the whole, diminished, although large outputs occurred in isolated years, for instance, a production of 40,000 tons in 1893 was followed by 60,000 tons in 1896 and 40,000 in 1897.

Maxwell has also given an explanation of the converse effect, namely, the production of longitudinal magnetization by twisting a wire when circularly magnetized by a current passing through it.

Further, it is pointed out by Korschelt and Heider that the hinder portion of the gut frequently acts in Arthropoda as an organ of nitrogenous excretion in the absence of any special excretory tubules, and that the production of such caeca from its surface in separate lines of descent does not involve any elaborate or unlikely process of growth.

No other country has been able to equal Brazil in the production of coffee, and under better labour conditions the country might compete with the foremost in the production of cane sugar, cotton and tobacco.

The branches of industry which have received special encouragement are those whose products are in universal request, such as cotton and woollen goods, and those which are in the service of natural production.

As a masterly production based on extensive investigation, we note the Wesselenyi Ferencz.

Theorems and formulae are appropriated wholesale without acknowledgment, and a production which may be described as the organized result of a century of patient toil presents itself to the world as the offspring of a single brain.

It has been maintained that this tendency to a severance of the hybrid stock into its components must favour the persistence of a new character of large volume suddenly appearing in a stock, and the observations of Mendel have been held to favour in this way the views of those who hold that the variations upon which natural selection has acted in the production of new species are not small variations but large and " discontinuous."

The suggestion requires further experimental testing, for which the case of the parthenogenetic production of a portion of the offspring, in such insects as the bee, offers a valuable opportunity for research.

The total production (including the Komati and Swaziland fields) to the end of 1908 was 1,097,685 oz.

Though several large nuggets have been found (the largest weighing 215 oz.), the total production is not great, the highest output obtained by washing being worth about £300,000 in one year.

The production since then has"greatly declined.

Where a chronic inflammatory process has taken possession of an organ, or, let us say, has been located in periosteum or other fibrous part, there is a great tendency to the production of cicatricial fibrous tissue in mass.

This splitting up of the fats previously combined with albumin in the cell by the action of natural ferments - lipases - and the setting free of the fats under the influence of toxins represent the normal and the pathological process in the production of so-called fatty degeneration.

They were unable to verify any direct connexion between its production and the organism of tubercle.

A stimulus may act on all sides and induce a general effect without direction of movement, but in the production of movement in a definite direction the stimulus must be applied unilaterally.

Thus, while increased pressure in the blood or lymph vessels may be one factor, and increased permeability of the capillary endothelium another, increased osmotic pressure in the tissues and lymph is probably the most important in the production of dropsy.

In 1848 Bontemps was obliged to leave France for political reasons and came to England, where he initiated the optical glass manufacture at Chance's glass works near Birmingham, and this firm ultimately attained a considerable reputation in the production of optical glass, especially of large disks for telescope objectives.

The refractive indices of all glasses at present available lie between 1.46 and 1 90, whereas transparent minerals are known having refractive indices lying considerably outside these limits; at least one of these, fluorite (calcium fluoride), is actually used by opticians in the construction of certain lenses, so that probably progress is to be looked for in a considerable widening of the limits of available optical materials; possibly such progress may lie in the direction of the artificial production of large mineral crystals.

Manufacture of Optical Glass.-In its earlier stages, the process for the production of optical glass closely resembles that used in the production of any other glass of the highest quality.

Constancy of composition of the raw materials and their careful and thorough admixture in constant proportions are therefore essential to the production of the required glasses.

The crucibles or pots used for the production of optical glass very closely resemble those used in the manufacture of flint glass for other purposes; they are " covered " and the molten materials are thus protected from the action of the furnace gases by the interposition of a wall of fireclay, but as crucibles for optical glass are used for only one fusion and are then broken up, they are not made so thick and heavy as those used in flint-glass making, since the latter remain in the furnace for many weeks.

The furnace used for the production of optical glass is generally constructed to take one crucible only, so that the heat of the furnace may be accurately adjusted to the requirements of the particular glass under treatment.

From the large masses great lenses and mirrors may be produced, while the smaller pieces are used for the production of the disks and slabs of moderate size, in which the optical glass of commerce is usually supplied.

It will be readily understood from the above account of the process of production that optical glass, relatively to other kinds of glass, is very expensive, the actual price varying from 3s.

For the production of coloured sheet-glass, however, the employment of pot furnaces is still almost universal, probably because the quantities of glass required of any one tint are insufficient to employ even a small tank furnace continuously; the exact control of the colour is also more readily attained with the smaller bulk of glass which has to be dealt with in pots.

Flashed glass is produced by taking either the first or the last gathering in the production of a cylinder out of a crucible containing the coloured " metal," the other gatherings being taken out of ordinary white sheet-glass.

The complicated and indirect process of sheet-glass manufacture has led to numerous inventions aiming at a direct method of production by more or less mechanical means.

For the production of thick sheets which are subsequently to be polished the process may thus claim considerable success, but it is not as yet possible to produce satisfactory sheet-glass by such means.

The production of coloured glass for " mosaic " windows has become a separate branch of glass-making.

The glass to be used for the production of plate is universally melted in pots or crucibles and not in open tank furnaces.

We have in the work of the monk Theophilus, Diversarum artium schedula, and in the probably earlier work of Eraclius, about the iith century, instructions as to the art of glass-making in general, and also as to the production of coloured and enamelled vessels, which these writers speak of as being practised by the Greeks.

In the 16th century it had become a trade of great importance, and about 1764 twenty-two furnaces were employed in the production of beads.

A more important outcome, however, of Italian influence was the production, in emulation of Venetian glass, of a glass made of refined potash, lime and sand, which was more colourless than the material it was intended to imitate.

The royal glass manufactory of La Granja de San Ildefonso was founded about 1725; in the first instance for the manufacture of mirror plates, but subsequently for the production of vases and table-ware in the French style.

It decomposes water at ordinary temperature with evolution of hydrogen but without production of silicon hydride, whilst cold hydrochloric acid attacks it vigorously with evolution of hydrogen and spontaneously inflammable silicon hydride.

In addition to the manufacture of woollen wares, for which it has long been known, there is now extensive production of vinegar, paraffin, potash and especially beetroot-sugar; while the surrounding district, which was formerly devoted in great part to marketgardening, is now turned almost entirely into beetroot fields.

This Greek production resembles the more ancient fourth book of Esdras in some respects.

It is a late production; for Ishmaelites are spoken of, the Crusades, and the taking of Jerusalem.

The late date of the production is obvious.

Production of flowers is uncertain under cultivation and seed is formed very rarely.

Jaggery production is entirely in native hands, and the greater part of the amount made is consumed locally; it only occasionally reaches the European market.

The details of manufacture of sugar from canes and of sugar from beetroots differ, but there are five operations in the production of the sugar of commerce from either material which are common to both processes.

But the great achievement of recent manufacture is the production, without the use of animal charcoal, of a cheaper, but good and wholesome article, in appearance equal to refined sugar for all intents and purposes, except for making preserves of fruits in the old-fashioned way.

Tha`alibi, a writer of the 11th century, says that Askar-Mokram had no equal for the quality and quantity of its sugar, " notwithstanding the great production of `Irak, Jorjan and India."

Under the bounty system, by which the protectionist countries of Europe stimulated the beet sugar industry by bounties on exports, the production of sugar in bounty-paying countries was encouraged and pushed far beyond the limits it could have reached without state aid.

It was agreed " to suppress the direct and indirect bounties which might benefit the production or export of sugar, and not to establish bounties of this kind during the whole duration of the convention," which was to come into force on the 1st of September 1903, and to remain in force five years, and thenceforward from year to year, in case no state denounced it twelve months before the 1st of September in any year.

This statement is quite consistent with the continuous production of new segments at the neck of the scolex, for such a process is analogous to the development of the segments in a Chaetopod, which is a perfectly distinct phenomenon from the regeneration of new segments to supply the place of a head or tail-end or some other portion that has been lesioned.

This change, which is called eosinophilia, indicates the production of a noxious substance in the blood.

When these various unions of dealers and of craftsmen embraced all the trades and branches of production in the town, little or no vitality remained in the old gild merchant; it ceased to have an independent sphere of activity.

Tobacco being cultivated over such a large area of the world, under very varying climatic conditions, and by many different races of mankind, the methods employed in its production naturally differ very considerably.

As the United States of America produce more tobacco than any other country it will be best to deal generally with conditions there and to refer to marked differences in dealing with production in other countries.

The successful production of cigar tobaccos from Cuban and Sumatran seed was a development of the late 19th century.

In the arts it is employed in the preparation of varnishes, and as a mordant for the production of colours on calico.
