The harbour of Onavoora, is a place of general rendezvous for the whale ships, cruising on the coast of Japan, and in the vicinity of the islands. The months of January, February, and March, being the least favourable for their business, they then leave their cruising ground, and go in search of refreshment. No place is so convenient for them as the Sandwich Islands, and the port of Onavoora, being the most commodious of any in the group, and affording an abundant supply of vegetables, hogs, &c.,--they all congregate there in the months above mentioned. The average number that visit the island in the course of the year, is upwards of fifty. More than twenty were there together, at several different periods of our stay, some of which remained a few days, some weeks, and a few one or two months, according to their several necessities. At such times the seamen, from having been long confined to the narrow precinct of their vessels, become very insubordinate, and frequently give way to the most licentious indulgences of their passions, regardless of every obligation of obedience due to their officers. We witnessed frequent instances of this kind, and had the satisfaction of being constantly useful to the captains of ships, and the whaling interest, by restraining the violent, and coercing them to a proper sense of duty. A most unpleasant occurrence took place about six weeks after our arrival at Onavoora, arising from this disposition of the seamen, and other causes, which was afterwards greatly misrepresented in this country. Some of the seamen of the Dolphin, who were on liberty, got into a frolic, and, associating themselves with many others belonging to the whale ships, determined to go to the houses of the high chiefs and missionaries, and demand the repeal of a restriction that deprived them of the society of females. They produced a riot that gave rise to a considerable degree of excitement for a few minutes; but Captain Percival, with some of the officers of the Dolphin, and captains of whale-ships, promptly suppressed it, and prevented any serious outrage. It was afterwards unjustly and most ungenerously ascribed to the officers of the Dolphin.
