No less than 665 interments are assigned to stage V, more than double the number attributable to stage IV. A Scottish unfield cannot, therefore, be regarded as the counterpart of the Late Bronze Age urnfields of southern England which, containing as many as a hundred interments, must correspond to a small village. The reduction in the cost of bronze is the outstanding characteristic of the Late Bronze Age, not only in Scotland but throughout Europe and far into Asia. Bronze was certainly worked in Scotland in stage V, since the moulds and tools of the workers are relatively numerous. In any case trade was essential for the existence of a Bronze Age since the industrial metals had to be imported nearly everywhere. For despite the reduction of cost, bronze as well as gold must have remained very expensive. The most natural centres of accumulation would be the old chieftainships. .
