Manufactures, as in a small bulk they frequently contain a great value, and can upon that account be transported at less expense from one country to another than most parts of rude produce, are, in almost all countries, the principal support of foreign trade. In countries, besides, less extensive and less favourably circumstanced for inferior commerce than China, they generally require the support of foreign trade. Without an extensive foreign market they could not well flourish, either in countries so moderately extensive as to afford but a narrow home market or in countries where the communication between one province and another was so difficult as to render it impossible for the goods of any particular place to enjoy the whole of that home market which the country could afford. The perfection of manufacturing industry, it must be remembered, depends altogether upon the division of labour; and the degree to which the division of labour can be introduced into any manufacture is necessarily regulated, it has already been shown, by the extent of the market. But the great extent of the empire of China, the vast multitude of its inhabitants, the variety of climate, and consequently of productions in its different provinces, and the easy communication by means of water carriage between the greater part of them, render the home market of that country of so great extent as to be alone sufficient to support very great manufactures, and to admit of very considerable subdivisions of labour. The home market of China is, perhaps, in extent, not much inferior to the market of all the different countries of Europe put together. A more extensive foreign trade, however, which to this great home market added the foreign market of all the rest of the world- especially if any considerable part of this trade was carried on in Chinese ships- could scarce fail to increase very much the manufactures of China, and to improve very much the productive powers of its manufacturing industry. By a more extensive navigation, the Chinese would naturally learn the art of using and constructing themselves all the different machines made use of in other countries, as well as the other improvements of art and industry which are practised in all the different parts of the world. Upon their present plan they have little opportunity except that of the Japanese.

The policy of ancient Egypt too, and that of the Gentoo government of Indostan, seem to have favoured agriculture more than all other employments.

Both in ancient Egypt and Indostan the whole body of the people was divided into different castes or tribes, each of which was confined, from father to son, to a particular employment or class of employments. The son of a priest was necessarily a priest; the son of a soldier, a soldier; the son of a labourer, a labourer; the son of a weaver, a weaver; the son of a tailor, a tailor, etc. In both countries, the caste of the priests held the highest rank, and that of the soldiers the next; and in both countries, the caste of the farmers and labourers was superior to the castes of merchants and manufacturers.

The government of both countries was particularly attentive to the interest of agriculture. The works constructed by the ancient sovereigns of Egypt for the proper distribution of the waters of the Nile were famous in antiquity; and the ruined remains of some of them are still the admiration of travellers. Those of the same kind which were constructed by the ancient sovereigns of Indostan for the proper distribution of the waters of the Ganges as well as of many other rivers, though they have been less celebrated, seem to have been equally great. Both countries, accordingly, though subject occasionally to dearths, have been famous for their great fertility. Though both were extremely populous, yet, in years of moderate plenty, they were both able to export great quantities of grain to their neighbours.

The ancient Egyptians had a superstitious aversion to the sea; and as the Gentoo religion does not permit its followers to light a fire, nor consequently to dress any victuals upon the water, it in effect prohibits them from all distant sea voyages. Both the Egyptians and Indians must have depended almost altogether upon the navigation of other nations for the exportation of their surplus produce; and this dependency, as it must have confined the market, so it must have discouraged the increase of this surplus produce. It must have discouraged, too, the increase of the manufactured produce more than that of the rude produce. Manufactures require a much more extensive market than the most important parts of the rude produce of the land. A single shoemaker will make more than three hundred pairs of shoes in the year; and his own family will not, perhaps, wear out six pairs. Unless therefore he has the custom of at least fifty such families as his own, he cannot dispose of the whole produce of his own labour. The most numerous class of artificers will seldom, in a large country, make more than one in fifty or one in a hundred of the whole number of families contained in it. But in such large countries as France and England, the number of people employed in agriculture has by some authors been computed at a half, by others at a third, and by no author that I know of, at less than a fifth of the whole inhabitants of the country. But as the produce of the agriculture of both France and England is, the far greater part of it, consumed at home, each person employed in it must, according to these computations, require little more than the custom of one, two, or at most, of four such families as his own in order to dispose of the whole produce of his own labour. Agriculture, therefore, can support itself under the discouragement of a confined market much better than manufactures. In both ancient Egypt and Indostan, indeed, the confinement of the foreign market was in some measure compensated by the conveniency of many inland navigations, which opened, in the most advantageous manner, the whole extent of the home market to every part of the produce of every different district of those countries. The great extent of Indostan, too, rendered the home market of that country very great, and sufficient to support a great variety of manufactures. But the small extent of ancient Egypt, which was never equal to England, must at all times have rendered the home market of that country too narrow for supporting any great variety of manufactures. Bengal, accordingly, the province of Indostan, which commonly exports the greatest quantity of rice, has always been more remarkable for the exportation of a great variety of manufactures than for that of its grain. Ancient Egypt, on the contrary, though it exported some manufactures, fine linen in particular, as well as some other goods, was always most distinguished for its great exportation of grain. It was long the granary of the Roman empire.

The sovereigns of China, of ancient Egypt, and of the different kingdoms into which Indostan has at different times been divided, have always derived the whole, or by far the most considerable part, of their revenue from some sort of land tax or land rent. This land tax or land rent, like the tithe in Europe, consisted in a certain proportion, a fifth, it is said, of the produce of the land, which was either delivered in kind, or paid in money, according to a certain valuation, and which therefore varied from year to year according to all the variations of the produce. It was natural therefore that the sovereigns of those countries should be particularly attentive to the interests of agriculture, upon the prosperity or declension of which immediately depended the yearly increase or diminution of their own revenue.

The policy of the ancient republics of Greece, and that of Rome, though it honoured agriculture more than manufactures or foreign trade, yet seems rather to have discouraged the latter employments than to have given any direct or intentional encouragement to the former. In several of the ancient states of Greece, foreign trade was prohibited altogether; and in several others the employments of artificers and manufacturers were considered as hurtful to the strength and agility of the human body, as rendering it incapable of those habits which their military and gymnastic exercises endeavoured to form in it, and as thereby disqualifying it more or less for undergoing the fatigues and encountering the dangers of war. Such occupations were considered as fit only for slaves, and the free citizens of the state were prohibited from exercising them. Even in those states where no such prohibition took place, as in Rome and Athens, the great body of the people were in effect excluded from all the trades which are, now commonly exercised by the lower sort of the inhabitants of towns. Such trades were, at Athens and Rome, all occupied by the slaves of the rich, who exercised them for the benefit of their masters, whose wealth, power, and protection made it almost impossible for a poor freeman to find a market for his work, when it came into competition with that of the slaves of the rich. Slaves, however, are very seldom inventive; and all the most important improvements, either in machinery, or in the arrangement and distribution of work which facilitate and abridge labour, have been the discoveries of freemen. Should a slave propose any improvement of this kind, his master would be very apt to consider the proposal as the suggestion of laziness, and a desire to save his own labour at the master's expense. The poor slave, instead of reward, would probably meet with much abuse, perhaps with some punishment. In the manufactures carried on by slaves, therefore, more labour must generally have been employed to execute the same quantity of work than in those carried on by freemen. The work of the former must, upon that account, generally have been dearer than that of the latter. The Hungarian mines, it is remarked by Mr. Montesquieu, though not richer, have always been wrought with less expense, and therefore with more profit, than the Turkish mines in their neighbourhood. The Turkish mines are wrought by slaves; and the arms of those slaves are the only machines which the Turks have ever thought of employing. The Hungarian mines are wrought by freemen, who employ a great deal of machinery, by which they facilitate and abridge their own labour. From the very little that is known about the price of manufactures in the times of the Greeks and Romans, it would appear that those of the finer sort were excessively dear. Silk sold for its weight in gold. It was not, indeed, in those times a European manufacture; and as it was all brought from the East Indies, the distance of the carriage may in some measure account for the greatness of price. The price, however, which a lady, it is said, would sometimes pay for a piece of very fine linen, seems to have been equally extravagant; and as linen was always either a European, or at farthest, an Egyptian manufacture, this high price can be accounted for only by the great expense of the labour which must have been employed about it, and the expense of this labour again could arise from nothing but the awkwardness of the machinery which it made use of. The price of fine woollens too, though not quite so extravagant, seems however to have been much above that of the present times. Some cloths, we are told by Pliny, dyed in a particular manner, cost a hundred denarii, or three pounds six shillings and eightpence the pound weight. Others dyed in another manner cost a thousand denarii the pound weight, or thirty-three pounds six shillings and eightpence. The Roman pound, it must be remembered, contained only twelve of our avoirdupois ounces. This high price, indeed, seems to have been principally owing to the dye. But had not the cloths themselves been much dearer than any which are made in the present times, so very expensive a dye would not probably have been bestowed upon them. The disproportion would have been too great between the value of the accessory and that of the principal. The price mentioned by the same author of some Triclinaria, a sort of woollen pillows or cushions made use of to lean upon as they reclined upon their couches at table, passes all credibility; some of them being said to have cost more than thirty thousand, others more than three hundred thousand pounds. This high price, too, is not said to have arisen from the dye. In the dress of the people of fashion of both sexes there seems to have been much less variety, it is observed by Doctor Arbuthnot, in ancient than in modern times; and the very little variety which we find in that of the ancient statues confirms his observation. He infers from this that their dress must upon the whole have been cheaper than ours; but the conclusion does not seem to follow. When the expense of fashionable dress is very great, the variety must be very small. But when, by the improvements in the productive powers of manufacturing art and industry, the expense of any one dress comes to be very moderate, the variety will naturally be very great. The rich, not being able to distinguish themselves by the expense of any one dress, will naturally endeavour to do so by the multitude and variety of their dresses.
