The Aryan tribes in the _Veda_ are acquainted with most of the metals. They have blacksmiths, coppersmiths and goldsmiths among them, besides carpenters, barbers and other artisans. They fight from chariots, and freely use the horse, although not yet the elephant, in war. They have settled down as husbandmen, till their fields with the plough, and live in villages or towns. But they also cling to their old wandering life, with their herds and "cattle-pens." Cattle, indeed, still form their chief wealth, the coin (Lat. _pecunia_) in which payments of fines are made; and one of their words for war literally means "a desire for cows." They have learned to build "ships," perhaps large river-boats, and seem to have heard something of the sea. Unlike the modern Hindus, the Aryans of the _Veda_ ate beef, used a fermented liquor or beer made from the _soma_ plant, and offered the same strong meat and drink to their gods. Thus the stout Aryans spread eastwards through northern India, pushed on from behind by later arrivals of their own stock, and driving before them, or reducing to bondage, the earlier "black-skinned" races. They marched in whole communities from one river-valley to another, each house-father a warrior, husbandman and priest, with his wife and his little ones, and cattle. Early states. About the beginning of the 6th century B.C. the settled country between the Himalaya mountains and the Nerbudda river was divided into sixteen independent states, some monarchies and some tribal republics, the most important of which were the four monarchies of Kosala, Magadha, the Vamsas and Avanti. Kosala, the modern kingdom of Oudh, appears to have been the premier state of India in 600 B.C. Later the supremacy was reft from it by the kingdom of Magadha, the modern Behar (q.v.). South of Kosala lay the kingdom of the Vamsas, and south of that again the kingdom of Avanti. In the north-west was Gandhara, on the banks of the Indus, in the neighbourhood of Peshawar. The history of these early states is only a confused record of war and intermarriages, and is still semi-mythical. The list of the sixteen states ignores everything north of the Himalayas, south of the Vindhyas, and east of the Ganges where it turns south. Capital cities.
