certain degree of heat, and could only flourish in the neighborhood of the sea, were insensibly exploded by industry and experience. 4. The cultivation of flax was transported from Egypt to Gaul, and enriched the whole country, however it might impoverish the particular lands on which it was sown. 5. The use of artificial grasses became familiar to the farmers both of Italy and the provinces, particularly the Lucerne, which derived its name and origin from Media. The assured supply of wholesome and plentiful food for the cattle during winter, multiplied the number of the docks and herds, which in their turn contributed to the fertility of the soil. To all these improvements may be added an assiduous attention to mines and fisheries, which, by employing a multitude of laborious hands, serve to increase the pleasures of the rich and the subsistence of the poor. The elegant treatise of Columella describes the advanced state of the Spanish husbandry under the reign of Tiberius; and it may be observed, that those famines, which so frequently afflicted the infant republic, were seldom or never experienced by the extensive empire of Rome. The accidental scarcity, in any single province, was immediately relieved by the plenty of its more fortunate neighbors.

Agriculture is the foundation of manufactures; since the productions of nature are the materials of art. Under the Roman empire, the labor of an industrious and ingenious people was variously, but incessantly, employed in the service of the rich. In their dress, their table, their houses, and their furniture, the favorites of fortune united every refinement of conveniency, of elegance, and of splendor, whatever could soothe their pride or gratify their sensuality. Such refinements, under the odious name of luxury, have been severely arraigned by the moralists of every age; and it might perhaps be more conducive to the virtue, as well as happiness, of mankind, if all possessed the necessaries, and none the superfluities, of life. But in the present imperfect condition of society, luxury, though it may proceed from vice or folly, seems to be the only means that can correct the unequal distribution of property. The diligent mechanic, and the skilful artist, who have obtained no share in the division of the earth, receive a voluntary tax from the possessors of land; and the latter are prompted, by a sense of interest, to improve those estates, with whose produce they may purchase additional pleasures. This operation, the particular effects of which are felt in every society, acted with much more diffusive energy in the Roman world. The provinces would soon have been exhausted of their wealth, if the manufactures and commerce of luxury had not insensibly restored to the industrious subjects the sums which were exacted from them by the arms and authority of Rome. As long as the circulation was confined within the bounds of the empire, it impressed the political machine with a new degree of activity, and its consequences, sometimes beneficial, could never become pernicious.

But it is no easy task to confine luxury within the limits of an empire. The most remote countries of the ancient world were ransacked to supply the pomp and delicacy of Rome. The forests of Scythia afforded some valuable furs. Amber was brought over land from the shores of the Baltic to the Danube; and the barbarians were astonished at the price which they received in exchange for so useless a commodity. There was a considerable demand for Babylonian carpets, and other manufactures of the East; but the most important and unpopular branch of foreign trade was carried on with Arabia and India. Every year, about the time of the summer solstice, a fleet of a hundred and twenty vessels sailed from Myos-hormos, a port of Egypt, on the Red Sea. By the periodical assistance of the monsoons, they traversed the ocean in about forty days. The coast of Malabar, or the island of Ceylon, was the usual term of their navigation, and it was in those markets that the merchants from the more remote countries of Asia expected their arrival. The return of the fleet of Egypt was fixed to the months of December or January; and as soon as their rich cargo had been transported on the backs of camels, from the Red Sea to the Nile, and had descended that river as far as Alexandria, it was poured, without delay, into the capital of the empire. The objects of oriental traffic were splendid and trifling; silk, a pound of which was esteemed not inferior in value to a pound of gold; precious stones, among which the pearl claimed the first rank after the diamond; and a variety of aromatics, that were consumed in religious worship and the pomp of funerals. The labor and risk of the voyage was rewarded with almost incredible profit; but the profit was made upon Roman subjects, and a few individuals were enriched at the expense of the public. As the natives of Arabia and India were contented with the productions and manufactures of their own country, silver, on the side of the Romans, was the principal, if not the only * instrument of commerce. It was a complaint worthy of the gravity of the senate, that, in the purchase of female ornaments, the wealth of the state
