[Trade.] There is no tradition of any old form of currency, such as beads, or gongs, though thin key-shaped pieces of iron (chabli) such as the Aos used to use as currency are occasionally owned as heirlooms. Trade was apparently always carried on by barter in the days before the British coinage came into use. Even nowadays cotton which is taken down to the plains is almost invariably bartered for salt. A peculiar custom obtains when mithan, ivory armlets and boar’s tushes are bought and sold. These articles are particularly liable to be infected with evil fortune, certain marks being regarded as unlucky, and so on. An old man is therefore always employed as an intermediary (lantse or thantsowe) between the parties, and he finally settles the price when the bargaining has gone on long enough. Any ill luck is believed to attach itself to him as nominal buyer, rather than to the real buyer, who pays him a commission of Re. 1 for a mithan, eight annas for an ivory armlet and four annas for a pair of boar’s tushes. If anything intimately connected with the person, such as a cloth or a dao, be sold the seller retains a thread from the cloth or scrapes a tiny shaving off the handle of the dao, for were he to sell the whole of something which was almost part of himself the buyer might be able to exercise some magical influence over him. [74] Loans. The rate of interest on loans varies according to the nature of the thing lent. That on money is usually 50 per cent. simple interest, running for two years only. The interest on rice is four baskets a year for every six baskets borrowed. The interest has to be paid year by year till the principal has been returned. A debt of seed paddy must be paid before all other debts. The highest rate of interest is demanded for salt, for which 100 per cent. per annum compound interest has to be paid. The result is that loans of salt are promptly repaid. Agriculture.
