The point is sometimes made that in primitive trade psychological satisfaction is obtained rather by the exchange of gifts and enhancement of prestige than by any economic advantage to the traders. It is possible, I think, to lay too much stress on this aspect of primitive trade at the expense of the more prosaic motive of material economic gain, though I do not, of course, wish to belittle the non-economic factors involved and indeed propose to draw attention to some of them. Naturally I shall take instances from my own experience, and these are mostly in areas with regular land contacts where the non-economic aspects of trade are likely to be less prominent than they are in self-contained and self-sufficient island communities. At the same time the first case I wish to examine is one of the inter-island trade in the Nicobar Islands.
