discoveries over the southern hemisphere. I am not qualified to examine, and I am not disposed to believe, their distant voyages to the Persian Gulf, or the Cape of Good Hope; but their ancestors might equal the labors and success of the present race, and the sphere of their navigation might extend from the Isles of Japan to the Straits of Malacca, the pillars, if we may apply that name, of an Oriental Hercules. Without losing sight of land, they might sail along the coast to the extreme promontory of Achin, which is annually visited by ten or twelve ships laden with the productions, the manufactures, and even the artificers of China; the Island of Sumatra and the opposite peninsula are faintly delineated as the regions of gold and silver; and the trading cities named in the geography of Ptolemy may indicate, that this wealth was not solely derived from the mines. The direct interval between Sumatra and Ceylon is about three hundred leagues: the Chinese and Indian navigators were conducted by the flight of birds and periodical winds; and the ocean might be securely traversed in square-built ships, which, instead of iron, were sewed together with the strong thread of the cocoanut. Ceylon, Serendib, or Taprobana, was divided between two hostile princes; one of whom possessed the mountains, the elephants, and the luminous carbuncle, and the other enjoyed the more solid riches of domestic industry, foreign trade, and the capacious harbor of Trinquemale, which received and dismissed the fleets of the East and West. In this hospitable isle, at an equal distance (as it was computed) from their respective countries, the silk merchants of China, who had collected in their voyages aloes, cloves, nutmeg, and sandal wood, maintained a free and beneficial commerce with the inhabitants of the Persian Gulf. The subjects of the great king exalted, without a rival, his power and magnificence: and the Roman, who confounded their vanity by comparing his paltry coin with a gold medal of the emperor Anastasius, had sailed to Ceylon, in an Æthiopian ship, as a simple passenger.

As silk became of indispensable use, the emperor Justinian saw with concern that the Persians had occupied by land and sea the monopoly of this important supply, and that the wealth of his subjects was continually drained by a nation of enemies and idolaters. An active government would have restored the trade of Egypt and the navigation of the Red Sea, which had decayed with the prosperity of the empire; and the Roman vessels might have sailed, for the purchase of silk, to the ports of Ceylon, of Malacca, or even of China. Justinian embraced a more humble expedient, and solicited the aid of his Christian allies, the Æthiopians of Abyssinia, who had recently acquired the arts of navigation, the spirit of trade, and the seaport of Adulis, * still decorated with the trophies of a Grecian conqueror. Along the African coast, they penetrated to the equator in search of gold, emeralds, and aromatics; but they wisely declined an unequal competition, in which they must be always prevented by the vicinity of the Persians to the markets of India; and the emperor submitted to the disappointment, till his wishes were gratified by an unexpected event. The gospel had been preached to the Indians: a bishop already governed the Christians of St. Thomas on the pepper-coast of Malabar; a church was planted in Ceylon, and the missionaries pursued the footsteps of commerce to the extremities of Asia. Two Persian monks had long resided in China, perhaps in the royal city of Nankin, the seat of a monarch addicted to foreign superstitions, and who actually received an embassy from the Isle of Ceylon. Amidst their pious occupations, they viewed with a curious eye the common dress of the Chinese, the manufactures of silk, and the myriads of silk-worms, whose education (either on trees or in houses) had once been considered as the labor of queens. They soon discovered that it was impracticable to transport the short-lived insect, but that in the eggs a numerous progeny might be preserved and multiplied in a distant climate. Religion or interest had more power over the Persian monks than the love of their country: after a long journey, they arrived at Constantinople, imparted their project to the emperor, and were liberally encouraged by the gifts and promises of Justinian. To the historians of that prince, a campaign at the foot of Mount Caucasus has seemed more deserving of a minute relation than the labors of these missionaries of commerce, who again entered China, deceived a jealous people by concealing the eggs of the silk-worm in a hollow cane, and returned in triumph with the spoils of the East. Under their direction, the eggs were hatched at the proper season by the artificial heat of dung; the worms were fed with mulberry leaves; they lived and labored in a foreign climate; a sufficient number of butterflies was saved to propagate the race, and trees were planted to supply the nourishment of the rising generations. Experience and reflection corrected the errors of a new attempt, and the Sogdoite ambassadors acknowledged, in the succeeding reign, that the Romans were not inferior to the natives of China in the education of the insects, and the manufactures
