On The Principles of Political Economy, and Taxation Part 2

and an additional capital of 500_l._ be consequently required to enable him to employ the same labour, whilst his commodities continue to sell for 8000_l._, he will no longer hesitate, but will at once purchase the machine, and will do the same annually, while wages continue above the original 5000_l._ But will he be able now to purchase the machine at the former price? will not its value be increased, in consequence of the rise of labour? It would be increased, if there were no stock employed in its construction, and no profits to be paid to the maker of it. If, for example, the machine were produced by 100 men working one year upon it with wages of 50_l._ each, and its price were 5000_l._, should those wages rise to 55_l._ its price would be 5500_l._: but this cannot be the case; less than 100 men are employed, or it could not be sold for 5000_l._; for out of the 5000_l._ must be paid the profits of the stock which employed the men. Suppose then that only eighty-five men were employed at an expense of 4250_l._ per annum, and that the 750_l._, which the sale of the machine would produce over and above the wages advanced to the men, const.i.tuted the profits of the engineer's stock.

When wages rose 10 per cent., he would be obliged to employ an additional capital of 425_l._, and would therefore employ 4675_l._, instead of 4250_l._, on which capital he would only get a profit of 325_l._ if he continued to sell his machine for 5000_l._; but this is precisely the case of all manufacturers and capitalists; the rise of wages affects them all. If therefore the maker of the machine should raise the price of his machine in consequence of a rise of wages, an unusual quant.i.ty of capital would be employed in the construction of such machines, till their price afforded only the usual profits. The manufacturer of hats, by the employment of the machine, if he sells his hats for 8000_l._, is precisely in the same situation as before; he employs no more capital, and obtains the same profits. The compet.i.tion of trade would not long allow this; for as capital would flow to the most profitable employment, he would be obliged to lower the price of hats, till his profits had sunk to the general level. Thus then is the public benefited by machinery: these mute agents are always the produce of much less labour than that which they displace, even when they are of the same money value. Through their influence, an increase in the price of provisions which raises wages, will affect fewer persons: it will reach, as in the above instance, eighty-five men instead of a hundred; and the saving which is the consequence, shews itself in the reduced price of the commodity manufactured. Neither machines nor any other commodities are raised in price, but all commodities which are made by machines fall, and fall in proportion to their durability.

It appears, then, that in proportion to the quant.i.ty and the durability of the fixed capital employed in any kind of production, the relative prices of those commodities on which such capital is employed, will vary inversely as wages; they will fall as wages rise. It appears too that no commodities whatever are raised in absolute price, merely because wages rise; that they never rise unless additional labour be bestowed on them; but that all commodities in the production of which fixed capital enters, not only do not rise with a rise of wages, but absolutely fall; fall too as much as 68 per cent., with a rise of seven per cent. in wages, if fixed capital be exclusively employed, and be of the duration of 100 years.

The above statement, which a.s.serts the compatibility of a rise of wages, with a fall of prices, has, I know, the disadvantage of novelty, and must trust to its own merits for advocates; whilst it has for its opponents, writers of distinguished and deserved reputation. It should however be carefully remembered, that in this whole argument I am supposing money to be of an invariable value; in other words, to be always the produce of the same quant.i.ty of una.s.sisted labour. Money, however, is a variable commodity; and the rise of wages as well as of commodities, is frequently occasioned by a fall in the value of money. A rise of wages from this cause will indeed be invariably accompanied by a rise in the price of commodities: but in such cases, it will be found that labour and all commodities have not varied in regard to each other, and that the variation has been confined to money.

Money, from its being a commodity obtained from a foreign country, from its being the general medium of exchange between all civilized countries, and from its being also distributed among those countries in proportions which are ever changing with every improvement in commerce and machinery, and with every increasing difficulty of obtaining food and necessaries for an increasing population, is subject to incessant variations. In stating the principles which regulate exchangeable value and price, we should carefully distinguish between those variations which belong to the commodity itself, and those which are occasioned by a variation in the medium in which value is estimated, or price expressed.

A rise in wages, from an alteration in the value of money, produces a general effect on price, and for that reason it produces no real effect whatever on profits. On the contrary, a rise of wages, from the circ.u.mstance of the labourer being more liberally rewarded, or from a difficulty of procuring the necessaries on which wages are expended, does not produce the effect of raising price, but has a great effect in lowering profits. In the one case, no greater proportion of the annual labour of the country is devoted to the support of the labourers, in the other case, a larger portion is so devoted.

It is according to the division of the whole produce of the land and labour of the country, between the three cla.s.ses of landlords, capitalists, and labourers, that we are to judge of rent, profit, and wages, and not according to the value at which that produce may be estimated in a medium which is confessedly variable.

It is not by the absolute quant.i.ty of produce obtained by either cla.s.s, that we can correctly judge of the rate of profit, rent, and wages, but by the quant.i.ty of labour required to obtain that produce. By improvements in machinery and agriculture, the whole produce may be doubled; but if wages, rent, and profit, be also doubled, these three will bear the same proportions to one another, and neither could be said to have relatively varied. But if wages partook not of the whole of this increase; if they, instead of being doubled, were only increased one half, if rent, instead of being doubled, were only increased three-fourths, and the remaining increase went to profit, it would, I apprehend, be correct for me to say, that rent and wages had fallen, while profits had risen; for if we had an invariable standard, by which to measure the value of this produce, we should find that a less value had fallen to the cla.s.s of labourers and landlords, and a greater to the cla.s.s of capitalists, than had been given before. We might find for example, that though the absolute quant.i.ty of commodities had been doubled, they were the produce of precisely the former quant.i.ty of labour. Of every hundred hats, coats, and quarters of corn produced,

if the labourers had 25 The landlords 25 And the capitalists 50 --- 100

And if, after these commodities were doubled in quant.i.ty, of every 100

The labourers had only 22 The landlords 22 And the capitalists 56 --- 100

In that case I should say, that wages and rent had fallen, and profits risen; though in consequence of the abundance of commodities, the quant.i.ty paid to the labourer and landlord would have increased in the proportion of 25 to 44. Wages are to be estimated by their real value, viz. by the quant.i.ty of labour and capital employed in producing them, and not by their nominal value either in coats, hats, money, or corn.

Under the circ.u.mstances I have just supposed, commodities would have fallen to half their former value; and, if money had not varied, to half their former price also. If then in this medium, which had not varied in value, the wages of the labourer should be found to have fallen, it will not the less be a real fall, because they might furnish him with a greater quant.i.ty of cheap commodities, than his former wages.

The variation in the value of money, however great, makes no difference in the _rate_ of profits; for suppose the goods of the manufacturer to rise from 1000_l._ to 2000_l._, or 100 per cent., if his capital, on which the variations of money have as much effect as on the value of produce, if his machinery, buildings, and stock in trade rise more than 100 per cent., his rate of profits has fallen, and he has a proportionably less quant.i.ty of the produce of the labour of the country at his command.

If, with capital of a given value, he double the quant.i.ty of produce, its value falls one half, and then it will bear the same proportion to the capital which produced it, as it did before.

If at the same time that he doubles the quant.i.ty of produce by the employment of the same capital, the value of money is by any accident lowered one half, the produce will sell for twice the money value that it did before; but the capital employed to produce it, will also be of twice its former money value; and therefore in this case too, the value of the produce will bear the same proportion to the value of the capital as it did before; and although the produce be doubled, rent, wages, and profits will only vary as the proportions vary, in which this double produce may be divided among the three cla.s.ses that share it.

It appears then that the acc.u.mulation of capital, by occasioning different proportions of fixed and circulating capital to be employed in different trades, and by giving different degrees of durability to such fixed capital, introduces a considerable modification to the rule, which is of universal application in the early states of society.

Commodities, though they continue to rise and fall, in proportion as more or less labour is necessary to their production, are also affected in their relative value by a rise or fall of profits, since equal profits may be derived from goods which sell for 2,000_l._ and from those which sell for 10,000_l._; and consequently the variations of those profits, independently of any increased or diminished quant.i.ty of labour required for the goods in question, must affect their prices in different proportions.

It appears too, that commodities may be lowered in value in consequence of a real rise of wages, but they never can be raised from that cause.

On the other hand, they may rise from a fall of wages, as they then lose the peculiar advantages of production, which high wages afforded them.

CHAPTER II.

ON RENT.

It remains however to be considered, whether the appropriation of land, and the consequent creation of rent, will occasion any variation in the relative value of commodities, independently of the quant.i.ty of labour necessary to production. In order to understand this part of the subject, we must inquire into the nature of rent, and the laws by which its rise or fall is regulated. Rent is that portion of the produce of the earth, which is paid to the landlord for the use of the original and indestructible powers of the soil. It is often however confounded with the interest and profit of capital, and in popular language the term is applied to whatever is annually paid by a farmer to his landlord. If, of two adjoining farms of the same extent, and of the same natural fertility, one had all the conveniences of farming buildings, were, besides, properly drained and manured, and advantageously divided by hedges, fences, and walls, while the other had none of these advantages, more remuneration would naturally be paid for the use of one, than for the use of the other; yet in both cases this remuneration would be called rent. But it is evident, that a portion only of the money annually to be paid for the improved farm, would be given for the original and indestructible powers of the soil; the other portion would be paid for the use of the capital which had been employed in ameliorating the quality of the land, and in erecting such buildings as were necessary to secure and preserve the produce. Adam Smith sometimes speaks of rent, in the strict sense to which I am desirous of confining it, but more often in the popular sense, in which the term is usually employed. He tells us, that the demand for timber, and its consequent high price, in the more southern countries of Europe, caused a rent to be paid for forests in Norway, which could before afford no rent. Is it not however evident, that the person who paid, what he thus calls rent, paid it in consideration of the valuable commodity which was then standing on the land, and that he actually repaid himself with a profit, by the sale of the timber? If, indeed, after the timber was removed, any compensation were paid to the landlord for the use of the land, for the purpose of growing timber or any other produce, with a view to future demand, such compensation might justly be called rent, because it would be paid for the productive powers of the land; but in the case stated by Adam Smith, the compensation was paid for the liberty of removing and selling the timber, and not for the liberty of growing it. He speaks also of the rent of coal mines, and of stone quarries, to which the same observation applies--that the compensation given for the mine or quarry, is paid for the value of the coal or stone which can be removed from them, and has no connexion with the original and indestructible powers of the land. This is a distinction of great importance, in an inquiry concerning rent and profits; for it is found, that the laws which regulate the progress of rent, are widely different from those which regulate the progress of profits, and seldom operate in the same direction. In all improved countries, that which is annually paid to the landlord, partaking of both characters, rent and profit, is sometimes kept stationary by the effects of opposing causes, at other times advances or recedes, as one or other of these causes preponderates. In the future pages of this work, then, whenever I speak of the rent of land, I wish to be understood as speaking of that compensation, which is paid to the owner of land for the use of its original and indestructible powers.

On the first settling of a country, in which there is an abundance of rich and fertile land, a very small proportion of which is required to be cultivated for the support of the actual population, or indeed can be cultivated with the capital which the population can command, there will be no rent; for no one would pay for the use of land, when there was an abundant quant.i.ty not yet appropriated, and therefore at the disposal of whosoever might choose to cultivate it.

On the common principles of supply and demand, no rent could be paid for such land, for the reason stated, why nothing is given for the use of air and water, or for any other of the gifts of nature which exist in boundless quant.i.ty. With a given quant.i.ty of materials, and with the a.s.sistance of the pressure of the atmosphere, and the elasticity of steam, engines may perform work, and abridge human labour to a very great extent; but no charge is made for the use of these natural aids, because they are inexhaustible, and at every man's disposal. In the same manner the brewer, the distiller, the dyer, make incessant use of the air and water for the production of their commodities; but as the supply is boundless, it bears no price.[5] If all land had the same properties, if it were boundless in quant.i.ty, and uniform in quality, no charge could be made for its use, unless where it possessed peculiar advantages of situation. It is only then because land is of different qualities with respect to its productive powers, and because in the progress of population, land of an inferior quality, or less advantageously situated, is called into cultivation, that rent is ever paid for the use of it. When, in the progress of society, land of the second degree of fertility is taken into cultivation, rent immediately commences on that of the first quality, and the amount of that rent will depend on the difference in the quality of these two portions of land.

When land of the third quality is taken into cultivation, rent immediately commences on the second, and it is regulated as before, by the difference in their productive powers. At the same time, the rent of the first quality will rise, for that must always be above the rent of the second, by the difference between the produce which they yield with a given quant.i.ty of capital and labour. With every step in the progress of population, which shall oblige a country to have recourse to land of a worse quality, to enable it to raise its supply of food, rent, on all the more fertile land, will rise.

Thus suppose land--No. 1, 2, 3,--to yield, with an equal employment of capital and labour, a net produce of 100, 90, and 80 quarters of corn.

In a new country, where there is an abundance of fertile land compared with the population, and where therefore it is only necessary to cultivate No. 1, the whole net produce will belong to the cultivator, and will be the profits of the stock which he advances. As soon as population had so far increased as to make it necessary to cultivate No.

2, from which ninety quarters only can be obtained after supporting the labourers, rent would commence on No. 1; for either there must be two rates of profit on agricultural capital, or ten quarters, or the value of ten quarters must be withdrawn from the produce of No. 1, for some other purpose. Whether the proprietor of the land, or any other person, cultivated No. 1, these ten quarters would equally const.i.tute rent; for the cultivator of No. 2 would get the same result with his capital, whether he cultivated No. 1, paying ten quarters for rent, or continued to cultivate No. 2, paying no rent. In the same manner it might be shewn that when No. 3 is brought into cultivation, the rent of No. 2 must be ten quarters, or the value of ten quarters, whilst the rent of No. 1 would rise to twenty quarters; for the cultivator of No. 3 would have the same profits whether he paid twenty quarters for the rent of No. 1, ten quarters for the rent of No. 2, or cultivated No. 3 free of all rent.

It often, and indeed commonly happens that before No. 2, 3, 4, or 5, or the inferior lands are cultivated, capital can be employed more productively on those lands which are already in cultivation. It may perhaps be found, that by doubling the original capital employed on No.

1, though the produce will not be doubled, will not be increased by 100 quarters, it may be increased by eighty-five quarters, and that this quant.i.ty exceeds what could be obtained by employing the same capital on land, No. 3.

In such case, capital will be preferably employed on the old land, and will equally create a rent; for rent is always the difference between the produce obtained by the employment of two equal quant.i.ties of capital and labour. If with a capital of 1000_l._ a tenant obtain 100 quarters of wheat from his land, and by the employment of a second capital of 1000_l._, he obtain a further return of eighty-five, his landlord would have the power at the expiration of his lease, of obliging him to pay fifteen quarters, or an equivalent value, for additional rent; for there cannot be two rates of profit. If he is satisfied with a diminution of fifteen quarters in the return for his second 1000_l._, it is because no employment more profitable can be found for it. The common rate of profit would be in that proportion, and if the original tenant refused, some other person would be found willing to give all which exceeded that rate of profit to the owner of the land from which he derived it.

In this case, as well as in the other, the capital last employed pays no rent. For the greater productive powers of the first 1000_l._, fifteen quarters is paid for rent, for the employment of the second 1000_l._ no rent whatever is paid. If a third 1000_l._ be employed on the same land, with a return of seventy-five quarters, rent will then be paid for the second 1000_l._ and will be equal to the difference between the produce of these two, or ten quarters; and at the same time the rent of the first 1000_l._ will rise from fifteen to twenty-five quarters; while the last 1000_l._ will pay no rent whatever.

If then good land existed in a quant.i.ty much more abundant than the production of food for an increasing population required, or if capital could be indefinitely employed without a diminished return on the old land, there could be no rise of rent; for rent invariably proceeds from the employment of an additional quant.i.ty of labour with a proportionally less return.

The most fertile, and most favourably situated land will be first cultivated, and the exchangeable value of its produce will be adjusted in the same manner as the exchangeable value of all other commodities, by the total quant.i.ty of labour necessary in various forms, from first to last, to produce it, and bring it to market. When land of an inferior quality is taken into cultivation, the exchangeable value of raw produce will rise, because more labour is required to produce it.

The exchangeable value of all commodities, whether they be manufactured, or the produce of the mines, or the produce of land, is always regulated, not by the less quant.i.ty of labour that will suffice for their production under circ.u.mstances highly favourable, and exclusively enjoyed by those who have peculiar facilities of production; but by the greater quant.i.ty of labour necessarily bestowed on their production by those who have no such facilities; by those who continue to produce them under the most unfavourable circ.u.mstances; meaning--by the most unfavourable circ.u.mstances, the most unfavourable under which the quant.i.ty of produce required renders it necessary to carry on the production.

Thus, in a charitable inst.i.tution, where the poor are set to work with the funds of benefactors, the general prices of the commodities, which are the produce of such work, will not be governed by the peculiar facilities afforded to these workmen, but by the common, usual, and natural difficulties, which every other manufacturer will have to encounter. The manufacturer enjoying none of these facilities might indeed be driven altogether from the market, if the supply afforded by these favoured workmen were equal to all the wants of the community; but if he continued the trade, it would be only on condition that he should derive from it the usual and general rate of profits on stock; and that could only happen when his commodity sold for a price proportioned to the quant.i.ty of labour bestowed on its production.[6]

It is true, that on the best land, the same produce would still be obtained with the same labour as before, but its value would be enhanced in consequence of the diminished returns obtained by those who employed fresh labour and stock on the less fertile land. Notwithstanding then, that the advantages of fertile over inferior lands are in no case lost, but only transferred from the cultivator, or consumer, to the landlord, yet since more labour is required on the inferior lands, and since it is from such land only that we are enabled to furnish ourselves with the additional supply of raw produce, the comparative value of that produce will continue permanently above its former level, and make it exchange for more hats, cloth, shoes, &c. &c. in the production of which no such additional quant.i.ty of labour is required.

The reason then, why raw produce rises in comparative value, is because more labour is employed in the production of the last portion obtained, and not because a rent is paid to the landlord. The value of corn is regulated by the quant.i.ty of labour bestowed on its production on that quality of land, or with that portion of capital, which pays no rent.

Corn is not high because a rent is paid, but a rent is paid because corn is high; and it has been justly observed, that no reduction would take place in the price of corn, although landlords should forego the whole of their rent. Such a measure would only enable some farmers to live like gentlemen, but would not diminish the quant.i.ty of labour necessary to raise raw produce on the least productive land in cultivation.

Nothing is more common than to hear of the advantages which the land possesses over every other source of useful produce, on account of the surplus which it yields in the form of rent. Yet when land is most abundant, when most productive, and most fertile, it yields no rent; and it is only when its powers decay, and less is yielded in return for labour, that a share of the original produce of the more fertile portions is set apart for rent. It is singular that this quality in the land, which should have been noticed as an imperfection, compared with the natural agents by which manufacturers are a.s.sisted, should have been pointed out as const.i.tuting its peculiar pre-eminence. If air, water, the elasticity of steam, and the pressure of the atmosphere, were of various qualities; if they could be appropriated, and each quality existed only in moderate abundance, they as well as the land would afford a rent, as the successive qualities were brought into use. With every worse quality employed, the value of the commodities in the manufacture of which they were used would rise, because equal quant.i.ties of labour would be less productive. Man would do more by the sweat of his brow, and nature perform less; and the land would be no longer pre-eminent for its limited powers.

If the surplus produce which land affords in the form of rent be an advantage, it is desirable that, every year, the machinery newly constructed should be less efficient than the old, as that would undoubtedly give a greater exchangeable value to the goods manufactured, not only by that machinery, but by all the other machinery in the kingdom; and a rent would be paid to all those who possessed the most productive machinery.[7]

The rise of rent is always the effect of the increasing wealth of the country, and of the difficulty of providing food for its augmented population. It is a symptom, but it is never a cause of wealth; for wealth often increases most rapidly while rent is either stationary, or even falling. Rent increases most rapidly, as the disposable land decreases in its productive powers. Wealth increases most rapidly in those countries where the disposable land is most fertile, where importation is least restricted, and where through agricultural improvements, productions can be multiplied without any increase in the proportional quant.i.ty of labour, and where consequently the progress of rent is slow.

If the high price of corn were the effect, and not the cause of rent, price would be proportionally influenced as rents were high or low, and rent would be a component part of price. But that corn which is produced with the greatest quant.i.ty of labour is the regulator of the price of corn, and rent does not and cannot enter in the least degree as a component part of its price. Adam Smith, therefore, cannot be correct in supposing that the original rule which regulated the exchangeable value of commodities, namely the comparative quant.i.ty of labour by which they were produced, can be at all altered by the appropriation of land and the payment of rent. Raw material enters into the composition of most commodities, but the value of that raw material as well as corn, is regulated by the productiveness of the portion of capital last employed on the land, and paying no rent; and therefore rent is not a component part of the price of commodities.

We have been hitherto considering the effects of the natural progress of wealth and population on rent, in a country in which the land is of variously productive powers; and we have seen, that with every portion of additional capital which it becomes necessary to employ on the land with a less productive return, rent would rise. It follows from the same principles, that any circ.u.mstances in the society which should make it unnecessary to employ the same amount of capital on the land, and which should therefore make the portion last employed more productive, would lower rent. Any great reduction in the capital of a country, which should materially diminish the funds destined for the maintenance of labour, would naturally have this effect. Population regulates itself by the funds which are to employ it, and therefore always increases or diminishes with the increase or diminution of capital. Every reduction of capital is therefore necessarily followed by a less effective demand for corn, by a fall of price, and by diminished cultivation. In the reverse order to that in which the acc.u.mulation of capital raises rent, will the diminution of it lower rent. Land of a less unproductive quality will be in succession relinquished, the exchangeable value of produce will fall, and land of a superior quality will be the land last cultivated, and that which will then pay no rent.

The same effects may however be produced when the wealth and population of a country are increased, if that increase is accompanied by such marked improvements in agriculture, as shall have the same effect of diminis.h.i.+ng the necessity of cultivating the poorer lands, or of expending the same amount of capital on the cultivation of the more fertile portions.

If a million of quarters of corn be necessary for the support of a given population, and it be raised on land of the qualities of No. 1, 2, 3; and if an improvement be afterwards discovered by which it can be raised on No. 1 and 2, without employing No. 3, it is evident that the immediate effect must be a fall of rent; for No. 2, instead of No. 3, will then be cultivated without paying any rent; and the rent of No. 1, instead of being the difference between the produce of No. 3 and No. 1, will be the difference only between No. 2 and 1. With the same population, and no more, there can be no demand for any additional quant.i.ty of corn; the capital and labour employed on No. 3, will be devoted to the production of other commodities desirable to the community, and can have no effect in raising rent unless the raw material from which they are made cannot be obtained without employing capital less advantageously on the land, in which case No. 3 must again be cultivated.

It is undoubtedly true, that the fall in the relative price of raw produce, in consequence of the improvement in agriculture, or rather in consequence of less labour being bestowed on its production, would naturally lead to increased acc.u.mulation; for the profits of stock would be greatly augmented. This acc.u.mulation would lead to an increased demand for labour, to higher wages, to an increased population, to a further demand for raw produce, and to an increased cultivation. It is only, however, after the increase in the population, that rent would be as high as before; that is to say, after No. 3 was taken into cultivation. A considerable period would have elapsed, attended with a positive diminution of rent.

But improvements in agriculture are of two kinds: those which increase the productive powers of the land, and those which enable us to obtain its produce with less labour. They both lead to a fall in the price of raw produce; they both affect rent, but they do not affect it equally.

If they did not occasion a fall in the price of raw produce, they would not be improvements; for it is the essential quality of an improvement to diminish the quant.i.ty of labour before required to produce a commodity; and this diminution cannot take place without a fall of its price or relative value.

The improvements which increase the productive powers of the land, are such as the more skilful rotation of crops, or the better choice of manure. These improvements absolutely enable us to obtain the same produce from a smaller quant.i.ty of land. If, by the introduction of a course of turnips, I can feed my sheep besides raising my corn, the land on which the sheep were fed becomes unnecessary, and the same quant.i.ty of raw produce is raised by the employment of a less quant.i.ty of land.

If I discover a manure which will enable me to make a piece of land produce 20 per cent. more corn, I may withdraw at least a portion of my capital from the most unproductive part of my farm. But, as I have before observed, it is not necessary that land should be thrown out of cultivation, in order to reduce rent: to produce this effect, it is sufficient that successive portions of capital are employed on the same land with different results, and that the portion which gives the least result should be withdrawn. If, by the introduction of the turnip husbandry, or by the use of a more invigorating manure, I can obtain the same produce with less capital, and without disturbing the difference between the productive powers of the successive portions of capital, I shall lower rent; for a different and more productive portion will be that which will form the standard from which every other will be reckoned. If, for example, the successive portions of capital yielded 100, 90, 80, 70; whilst I employed these four portions, my rent would be 60, or the difference between

70 and 100 = 30 } { 100 70 and 90 = 20 } { 90 70 and 80 = 10 } whilst the produce { 80 -- } would be 340 { 70 60 } { --- { 340
