The word _tauvu_ means literally "Sprung from the same root," or "of common origin." It is applied to two or more tribes who may live in different islands, speak different dialects, and have, in short, nothing in common but their god. They do not necessarily intermarry; they may have held no intercourse for generations; yet, though each may have forgotten the names of its chiefs three generations back, the site of its ancient home, and the traditions of its migrations, it never forgets the tribe with which it is _tauvu_. Members of that tribe may run riot in its village, slaughter its animals, and ravage its plantations, while it sits smiling by; for the spoilers are its brothers, worshippers of its common ancestor, and are entitled in the fullest sense to the "freedom of the city." In several instances I have traced back the bond of tauvu to its origin, the marriage of the sister of some high chief with the head of a distant clan. Her rank was so transcendent that she brought into her husband's family a measure of the godhead of her ancestors, and her descendants have thenceforth reverenced her forefathers in preference to those of her husband. But in the majority of cases--and it is the exception to find a clan which is not tauvu to some other--the bond is too remote for tradition to have preserved its origin, and in these the two clans were probably offshoots from the same stock. Perhaps there was a quarrel between brothers, and one of them was driven out with his family to find another home; or a young swarm from an overcrowded hive may have crossed the water to seek wider planting lands for their support, as the first Aryan emigrants burst through the barriers of their cradle-land and overran Europe. Had the Aryans been ancestor-worshippers Rome would have been _tauvu_ with Athens, and the descendants of the youths driven forth in the Ver Sacrum _tauvu_ with Rome. The general tendency of the bonds of _tauvu_ in the western portion of the group is to confirm the sagas of Nakauvandra in suggesting that the cradle-land of the Fijians was the north-western corner of Vitilevu, whence the tide of emigration set northward to Mbua, eastward along the Tailevu coast, and south-eastward down the Wainimbuka branch of the Rewa river. Besides the saga of Turukawa, printed in another chapter, there are fragments of a still earlier poem relating the first arrival of the _Kalou-Vu_ in a great canoe, the _Kaunitoni_, tempest-driven from a land in the far West. The fragmentary saga of the _Kaunitoni_ must be accepted with caution, since it was committed to writing so late as 1891, when educated Fijians were already aware that Europeans were seeking evidence of their arrival in the group.
