=24.= SOUTH-EASTERN ASIA. _India_ extends from the Indus eastward to the boundaries of China, being bounded on the south by the Indian Ocean, and on the north by the Himala´yas, from whose snowy heights many great rivers descend to fertilize the plains. The richness of the soil fits it for the abode of a swarming population; and roads, temples, and other structures, dating from a very remote period, attest the skill and industry of the people. Herod´otus[3] names them as the greatest and wealthiest of nations, though he had not seen them. It was only in the fifth century before Christ that the Indian peninsulas became distinctly known to the Greeks; and it was two centuries later, in the invasion by Alexander, that the remarkable features of the country were first described to the Western world by eye-witnesses. “Wool-bearing trees” were mentioned as a most peculiar production; for cotton, as well as sugar, was first produced in India. The pearl fisheries, however, of the eastern coast, the diamonds of Golcon´da, the rubies of Mysore´, as well as the abundant gold of the river-beds, the aromatic woods of the forests, and the fine fabrics of cotton, silk, and wool, for which India was already famous,[4] drew the merchants of Phœnicia at a much earlier period to the banks of the Indus. =25.= _China_ was even less known than India to the inhabitants of the ancient world. The province of Se´rica, which formed the north-western corner of what is now the Chinese Empire, was visited, however, by Babylonian and Phœnician merchants, for its most peculiar product, silk. The extreme reserve of the Chinese in their dealings with foreigners, may already be observed in the account given by Herodotus of their trade with the neighboring Scythians. The Sericans deposited their bales of wool or silk in a solitary building called the Stone Tower. The merchants then approached, deposited beside the goods a sum which they were willing to pay, and retired out of sight. The Sericans returned, and, if satisfied with the bargain, took away the money, leaving the goods; but if they considered the payment insufficient, they took away the goods and left the money. The Chinese have always been remarkable for their patient and thorough tillage of the soil. Chin-nong, their fourth emperor, invented the plow; and for thousands of years custom required each monarch, among the ceremonies of his coronation, to guide a plow around a field, thus paying due honor to agriculture, as the art most essential to the civilization, or, rather, to the very existence of a state.
