"Savage and objectionable as the is, it has played an important part in the past of the Australian race, for it tended strongly to keep up communication between the tribes. The renewal of friendly relations between tribes is always marked by a corroboree. When tribes corroboree, it is a gauge of peace; and this peace is, so far as I know, ratified in no other way. A quarrel between two associated tribes is usually brought to an end by an invitation to fight which invariably ends in a corroboree. A great point in it, as a medium of reconciliation, is that it excludes for the most part explanations, questions, and reflections. Two tribes at variance meet, a fight ensues, in which generally not much harm is done and then a corroboree takes place, and every point of honour is satisfied ipso facto. On the other hand, ill feelings, and eventually war, not infrequently originate at these meetings, and almost invariably as the result of outrages on women. Though advantages of some sorts have certainly resulted from the corroboree it was undoubtedly, especially when several tribes were present, often an occasion of licentiousness and violence."
