LETTER III.
Sir, Dec. 15,1759.
It is the common fate of erroneous positions, that they are betrayed by defence, and obscured by explanation; that their authors deviate from the main question into incidental disquisitions, and raise a mist where they should let in light.
Of all these concomitants of errours, the letter of Dec. 10, in favour of elliptical arches, has afforded examples. A great part of it is spent upon digressions. The writer allows, that the first excellence of a bridge is undoubtedly strength: but this concession affords him an opportunity of telling us, that strength, or provision against decay, has its limits; and of mentioning the monument and cupola, without any advance towards evidence or argument.
The first excellence of a bridge is now allowed to be strength; and it has been asserted, that a semi-ellipsis has less strength than a semicircle. To this he first answers, that granting this position for a moment, the semi-ellipsis may yet have strength sufficient for the purposes of commerce. This grant, which was made but for a moment, needed not to have been made at all; for, before he concludes his letter, he undertakes to prove, that the elliptical arch must, in all respects, be superiour in strength to the semicircle. For this daring assertion he made way by the intermediate paragraphs, in which he observes, that the convexity of a semi-ellipsis may be increased at will to any degree that strength may require; which is, that an elliptical arch may be made less elliptical, to be made less weak; or that an arch, which, by its elliptical form, is superiour in strength to the semicircle, may become almost as strong as a semicircle, by being made almost semicircular.
That the longer diameter of an ellipsis may be shortened, till it shall differ little from a circle, is indisputably true; but why should the writer forget the semicircle differs as little from such an ellipsis? It seems that the difference, whether small or great, is to the advantage of the semicircle; for he does not promise that the elliptical arch, with all the convexity that his imagination can confer, will stand without cramps of iron, and melted lead, and large stones, and a very thick arch; assistances which the semicircle does not require, and which can be yet less required by a semi-ellipsis, which is, in all respects, superiour in strength.
Of a man who loves opposition so well, as to be thus at variance with himself, little doubt can be made of his contrariety to others; nor do I think myself entitled to complain of disregard from one, with whom the performances of antiquity have so little weight; yet, in defiance of all this contemptuous superiority, I must again venture to declare, that a straight line will bear no weight; being convinced, that not even the science of Vasari can make that form strong which the laws of nature have condemned to weakness. By the position, that a straight line will bear nothing, is meant, that it receives no strength from straightness; for that many bodies, laid in straight lines, will support weight by the cohesion of their parts, every one has found, who has seen dishes on a shelf, or a thief upon the gallows. It is not denied, that stones may be so crushed together by enormous pressure on each side, that a heavy mass may safely be laid upon them; but the strength must be derived merely from the lateral resistance; and the line, so loaded, will be itself part of the load.
The semi-elliptical arch has one recommendation yet unexamined: we are told, that it is difficult of execution. Why difficulty should be chosen for its own sake, I am not able to discover; but it must not be forgotten, that, as the convexity is increased, the difficulty is lessened; and I know not well, whether this writer, who appears equally ambitious of difficulty, and studious of strength, will wish to increase the convexity for the gain of strength, or to lessen it for the love of difficulty.
The friend of Mr. M —— , however he may be mistaken in some of his opinions, does not want the appearance of reason, when he prefers facts to theories; and that I may not dismiss the question without some appeal to facts, I will borrow an example, suggested by a great artist, and recommended to those who may still doubt which of the two arches is the stronger, to press an egg first on the ends, and then upon the sides.
I am, Sir, yours, &c.
SOME THOUGHTS ON AGRICULTURE, BOTH ANCIENT AND MODERN, WITH AN ACCOUNT OF THE HONOUR DUE TO AN ENGLISH FARMER.
Agriculture, in the primeval ages, was the common parent of traffick; for the opulence of mankind then consisted in cattle, and the product of tillage, which are now very essential for the promotion of trade in general, but more particularly so to such nations as are most abundant in cattle, corn, and fruits. The labour of the farmer gives employment to the manufacturer, and yields a support for the other parts of the community: it is now the spring which sets the whole grand machine of commerce in motion; and the sail could not be spread without the assistance of the plough. But though the farmers are of such utility in a state, we find them, in general, too much disregarded among the politer kind of people in the present age; while we cannot help observing the honour that antiquity has always paid to the profession of the husbandman; which naturally leads us into some reflections upon that occasion.
Though mines of gold and silver should be exhausted, and the specie made of them lost; though diamonds and pearls should remain concealed in the bowels of the earth, and the womb of the sea; though commerce with strangers be prohibited; though all arts, which have no other object than splendour and embellishment, should be abolished; yet the fertility of the earth alone would afford an abundant supply for the occasions of an industrious people, by furnishing subsistence for them, and such armies as should be mustered in their defence. We, therefore, ought not to be surprised, that agriculture was in so much honour among the ancients; for it ought rather to seem wonderful that it should ever cease to be so, and that the most necessary and most indispensable of all professions should have fallen into any contempt.
Agriculture was in no part of the world in higher consideration than Egypt, where it was the particular object of government and policy; nor was any country ever better peopled, richer, or more powerful. The satrapae, among the Assyrians and Persians, were rewarded, if the lands in their governments were well cultivated; but were punished, if that part of their duty was neglected. Africa abounded in corn; but the most famous countries were Thrace, Sardinia, and Sicily.
Cato, the censor, has justly called Sicily the magazine and nursing mother of the Roman people, who were supplied from thence with almost all their corn, both for the use of the city, and the subsistence of her armies: though we also find in Livy, that the Romans received no inconsiderable quantities of corn from Sardinia. But, when Rome had made herself mistress of Carthage and Alexandria, Africa and Egypt became her storehouses; for those cities sent such numerous fleets every year, freighted with corn, to Rome, that Alexandria alone annually supplied twenty millions of bushels: and, when the harvest happened to fail in one of these provinces, the other came in to its aid, and supported the metropolis of the world, which, without this supply, would have been in danger of perishing by famine. Rome actually saw herself reduced to this condition under Augustus; for there remained only three days’ provision of corn in the city: and that prince was so full of tenderness for the people, that he had resolved to poison himself, if the expected fleets did not arrive before the expiration of that time; but they came; and the preservation of the Romans was attributed to the good fortune of their emperour: but wise precautions were taken to avoid the like danger for the future.
When the seat of empire was transplanted to Constantinople, that city was supplied in the same manner: and when the emperour, Septimius Severus, died, there was corn in the publick magazines for seven years, expending daily 75,000 bushels in bread, for 600,000 men.
The ancients were no less industrious in the cultivation of the vine than in that of corn, though they applied themselves to it later: for Noah planted it by order, and discovered the use that might be made of the fruit, by pressing out and preserving the juice. The vine was carried by the offspring of Noah into the several coun
tries of the world; but Asia was the first to experience the sweets of this gift; from whence it was imparted to Europe and Africa. Greece and Italy, which were distinguished in so many other respects, were particularly so by the excellency of their wines. Greece was most celebrated for the wines of Cyprus, Lesbos, and Chio; the former of which is in great esteem at present, though the cultivation of the vine has been generally suppressed in the Turkish dominions. As the Romans were indebted to the Grecians for the arts and sciences, so were they, likewise, for the improvement of their wines; the best of which were produced in the country of Capua, and were called the Massick, Calenian, Formian, Caecuban, and Falernian, so much celebrated by Horace. Domitian passed an edict for destroying all the vines, and that no more should be planted throughout the greatest part of the west; which continued almost two hundred years afterwards, when the emperour Probus employed his soldiers in planting vines in Europe, in the same manner as Hannibal had formerly employed his troops in planting olive trees in Africa. Some of the ancients have endeavoured to prove, that the cultivation of vines is more beneficial than any other kind of husbandry: but, if this was thought so in the time of Columella, it is very different at present; nor were all the ancients of his opinion, for several gave the preference to pasture lands.
The breeding of cattle has always been considered as an important part of agriculture. The riches of Abraham, Laban, and Job, consisted in their flocks and herds. We also find from Latinus in Virgil, and Ulysses in Homer, that the wealth of those princes consisted in cattle. It was, likewise, the same among the Romans, till the introduction of money, which put a value upon commodities, and established a new kind of barter. Varro has not disdained to give an extensive account of all the beasts that are of any use to the country, either for tillage, breed, carriage, or other conveniencies of man. And Cato, the censor, was of opinion, that the feeding of cattle was the most certain and speedy method of enriching a country.
Luxury, avarice, injustice, violence, and ambition, take up their ordinary residence in populous cities; while the hard and laborious life of the husbandman will not admit of these vices. The honest farmer lives in a wise and happy state, which inclines him to justice, temperance, sobriety, sincerity, and every virtue that can dignify human nature. This gave room for the poets to feign, that Astraea, the goddess of justice, had her last residence among husbandmen, before she quitted the earth. Hesiod and Virgil have brought the assistance of the Muses in praise of agriculture. Kings, generals, and philosophers, have not thought it unworthy their birth, rank, and genius, to leave precepts to posterity upon the utility of the husbandman’s profession. Hiero, Attalus, and Archelaus, kings of Syracuse, Pergamus, and Cappadocia, have composed books for supporting and augmenting the fertility of their different countries. The Carthaginian general, Mago, wrote twenty-eight volumes upon this subject; and Cato, the censor, followed his example. Nor have Plato, Xenophon, and Aristotle, omitted this article, which makes an essential part of their politicks. And Cicero, speaking of the writings of Xenophon, says, “How fully and excellently does he, in that book called his Economicks, set out the advantages of husbandry, and a country life!”
When Britain was subject to the Romans, she annually supplied them with great quantities of corn; and the isle of Anglesea was then looked upon as the granary for the western provinces; but the Britons, both under the Romans and Saxons, were employed like slaves at the plough. On the intermixture of the Danes and Normans, possessions were better regulated, and the state of vassalage gradually declined, till it was entirely worn off under the reigns of Henry the seventh and Edward the sixth; for they hurt the old nobility by favouring the commons, who grew rich by trade, and purchased estates.
The wines of France, Portugal, and Spain, are now the best; while Italy can only boast of the wine made in Tuscany. The breeding of cattle is now chiefly confined to Denmark and Ireland. The corn of Sicily is still in great esteem, as well as what is produced in the northern countries: but England is the happiest spot in the universe for all the principal kinds of agriculture, and especially its great produce of corn.
The improvement of our landed estates is the enrichment of the kingdom; for, without this, how could we carry on our manufactures, or prosecute our commerce? We should look upon the English farmer as the most useful member of society. His arable grounds not only supply his fellow-subjects with all kinds of the best grain, but his industry enables him to export great quantities to other kingdoms, which might otherwise starve; particularly Spain and Portugal; for, in one year, there have been exported 51,520 quarters of barley, 219,781 of malt, 1,920 of oatmeal, 1,329 of rye, and 153,343 of wheat; the bounty on which amounted to 72,433 pounds. What a fund of treasure arises from his pasture lands, which breed such innumerable flocks of sheep, and afford such fine herds of cattle, to feed Britons, and clothe mankind! He rears flax and hemp for the making of linen; while his plantations of apples and hops supply him with generous kinds of liquors.
The land-tax, when at four shillings in the pound, produces 2,000,000 pounds a year. This arises from the labour of the husbandman: it is a great sum; but how greatly is it increased by the means it furnishes for trade! Without the industry of the farmer, the manufacturer could have no goods to supply the merchant, nor the merchant find any employment for the mariners: trade would be stagnated; riches would be of no advantage to the great; and labour of no service to the poor.
The Romans, as historians all allow,
Sought, in extreme distress, the rural plough;
Io triumphe! for the village swain,
Retired to be a nobleman again.
FURTHER THOUGHTS ON AGRICULTURE. FROM THE VISITER FOR MARCH, 1756, P. 111.
At my last visit, I took the liberty of mentioning a subject, which, I think, is not considered with attention proportionate to its importance. Nothing can more fully prove the ingratitude of mankind, a crime often charged upon them, and often denied, than the little regard which the disposers of honorary rewards have paid to agriculture, which is treated as a subject so remote from common life, by all those who do not immediately hold the plough, or give fodder to the ox, that I think there is room to question, whether a great part of mankind has yet been informed that life is sustained by the fruits of the earth. I was once, indeed, provoked to ask a lady of great eminence for genius, “Whether she knew of what bread is made?”
I have already observed, how differently agriculture was considered by the heroes and wise men of the Roman commonwealth, and shall now only add, that even after the emperours had made great alteration in the system of life, and taught men to portion out their esteem to other qualities than usefulness, agriculture still maintained its reputation, and was taught by the polite and elegant Celsus among the other arts.
The usefulness of agriculture I have already shown; I shall now, therefore, prove its necessity: and, having before declared, that it produces the chief riches of a nation, I shall proceed to show, that it gives its only riches, the only riches which we can call our own, and of which we need not fear either deprivation or diminution.
Of nations, as of individuals, the first blessing is independence. Neither the man nor the people can be happy to whom any human power can deny the necessaries or conveniencies of life. There is no way of living without the need of foreign assistance, but by the product of our own land, improved by our own labour. Every other source of plenty is perishable or casual.
Trade and manufactures must be confessed often to enrich countries; and we ourselves are indebted to them for those ships by which we now command the sea from the equator to the poles, and for those sums with which we have shown ourselves able to arm the nations of the north in defence of regions in the western hemisphere. But trade and manufactures, however profitable, must yield to the cultivation of lands in usefulness and dignity.
Commerce, however we may please ourselves with the contrary opinion, is one of the daughters of Fortune, inconstant and deceitful as her mother; she chooses her resid
ence where she is least expected, and shifts her abode when her continuance is, in appearance, most firmly settled. Who can read of the present distresses of the Genoese, whose only choice now remaining is, from what monarch they shall solicit protection? Who can see the Hanseatick towns in ruins, where, perhaps, the inhabitants do not always equal the number of the houses, but he will say to himself, these are the cities, whose trade enabled them once to give laws to the world, to whose merchants princes sent their jewels in pawn, from whose treasuries armies were paid, and navies supplied? And who can then forbear to consider trade as a weak and uncertain basis of power, and wish to his own country greatness more solid, and felicity more durable?
It is apparent, that every trading nation flourishes, while it can be said to flourish, by the courtesy of others. We cannot compel any people to buy from us, or to sell to us. A thousand accidents may prejudice them in favour of our rivals; the workmen of another nation may labour for less price, or some accidental improvement, or natural advantage, may procure a just preference to their commodities; as experience has shown, that there is no work of the hands, which, at different times, is not best performed in different places.
Traffick, even while it continues in its state of prosperity, must owe its success to agriculture; the materials of manufacture are the produce of the earth. The wool which we weave into cloth, the wood which is formed into cabinets, the metals which are forged into weapons, are supplied by nature with the help of art. Manufactures, indeed, and profitable manufactures, are sometimes raised from imported materials, but then we are subjected, a second time, to the caprice of our neighbours. The natives of Lombardy might easily resolve to retain their silk at home, and employ workmen of their own to weave it. And this will certainly be done when they grow wise and industrious, when they have sagacity to discern their true interest, and vigour to pursue it.
