About 1760, Nailatikau being Vunivalu, or secular king, the chiefs moved from the mainland to the islet, which was known thenceforward as Mbau. The fishermen had for some time been waxing insubordinate, and their offences culminated in the eating of an enormous fish which ought, by custom, to have been presented to their chiefs. They were expelled from the island. The Levuka tribe fled to Lakemba, still retaining their hereditary right to instal each successive Vunivalu in his office. The Mbau chiefs scarped away the face of the island so as to form the embankment upon which the present town is built. Nailatikau died about 1770, and was succeeded by his second son Mbanuve. During his reign the fishermen of Lasakau from the island of Mbenka, and of Soso, from the island of Kandavu, were employed in reclaiming more land from the sea, and were allowed to settle on the island. The first intermarriage with the Rewa chiefs dates from this period. The story goes that a Rewa canoe, being hailed as she passed Mbau, replied that she was bound for Verata for a princess to mate with the king of Rewa; that the crew was induced to take a Mbau lady in her stead, and that a Rewa princess was sent to Mbau in exchange. Thus the Mbau chiefs passed from being _parvenus_ to a place in the aristocracy of their adopted country. As the date of the first arrival of Europeans, which was to have so profound an influence upon the natives, is in dispute, it may be well to mention the recorded voyages chronologically. Tasman, who sighted Vanua-mbalavu in 1643, did not communicate with the natives. Cook, who had had information about the group from Fijians settled in the Friendly Islands, discovered the outlying island of Vatoa, the southeasterly limit of the group, and called it Turtle Island, but bore away to the north-east. In April 1791, a few days after the famous Mutiny of the _Bounty_, Bligh passed through the centre of the group in an open boat. His urgent need of provisions would doubtless have impelled him to communicate with the shore had he possessed firearms, and had he not just lost his quartermaster in a treacherous attack made upon him by the natives of Tofua. As it was he was chased along the northern coast of Vitilevu by two sailing canoes, which only left him when he cleared the group by Round Island, the most northerly of the Yasawa sub-group.
