Towha, who was a relation of Otoo, and chief of the district of Tettaha, a man of much weight in the island, and who had been commander-in-chief of the armament fitted out against Eimeo in 1774, happened not to be at Matavai at this time; and, consequently, was not present at any of these consultations. It, however, appeared that he was no stranger to what was transacted; and that he entered with more spirit into the affair than any other chief. For, early in the morning of the 1st of September, a messenger arrived from him to acquaint Otoo that he had killed a man to be sacrificed to the _Eatooa_, to implore the assistance of the god against Eimeo. This act of worship was to be performed at the great _Morai_ at Attahooroo; and Otoo's presence, it seems, was absolutely necessary on that solemn occasion. That the offering of human sacrifices is part of the religious institutions of this island, had been mentioned by Mons. de Bougainville, on the authority of the native whom he carried with him to France. During my last visit to Otaheite, and while I had opportunities of conversing with Omai on the subject, I had satisfied myself that there was too much reason to admit that such a practice, however inconsistent with the general humanity of the people, was here adopted. But as this was one of those extraordinary facts, about which many are apt to retain doubts, unless the relater himself has had ocular proof to confirm what he had heard from others, I thought this a good opportunity of obtaining the highest evidence of its certainty, by being present myself at the solemnity; and, accordingly, proposed to Otoo that I might be allowed to accompany him. To this he readily consented; and we immediately set out in my boat, with my old friend Potatou, Mr Anderson, and Mr Webber; Omai following in a canoe. In our way we landed upon a little island, which lies off Tettaha, where we found Towha and his retinue. After some little conversation between the two chiefs, on the subject of the war, Towha addressed himself to me, asking my assistance. When I excused myself, he seemed angry, thinking it strange, that I, who had always declared myself to be the friend of their island, would not now go and fight against its enemies. Before we parted, he gave to Otoo two or three red feathers, tied up in a tuft, and a lean half-starved dog was put into a canoe that was to accompany us. We then embarked again, taking on board a priest who was to assist at the solemnity.
