The Loyalty group was discovered at the beginning of the 19th century, and Dumont d'Urville laid down the several islands in his chart.
The Narrative contains much interesting material concerning the manners and customs i This discovery was made on the 19th of January 1840, one day before Dumont d'Urville sighted Adelie Land about 400 m.
The most important and best-known rivers are the Amberno, in the north, discharging by a wide delta at Point d'Urville; the Kaiserin Augusta, which, rising in the Charles Louis range, and entering the Pacific near Cape della Torre, is navigable by ocean steamers for 180 m.; the Ottilien, a river of great length, which discharges into the sea a short distance south of the last named; and the Mambare, navigable by steam-launch for 50 m.
D'Entrecasteaux (1793) and Dumont d'Urville (1827-1840), the eastern coasts were surveyed by Captains F.P. Blackwood (1835).
Dumont d'Urville describes four such villages in the Bay of Dorei, containing from eight to fifteen blocks or clusters of houses, each block separately built on piles, and consisting of a row of distinct dwellings.
In 1834 Dr Debell Bennett made scientific researches in the Society, Hawaiian and Marquesas Islands, in 1835 Captain Robert Fitzroy was accompanied by Charles Darwin, and in 1836 sqq., Abel Aubert du Petit-Thouars was carrying on the work of the French in the Pacific. During his voyage of 1837-1840, Dumont d'Urville was again in Polynesia, working westward from the Paumotu and Marquesas Islands by Fiji and the Solomon, Loyalty and Louisiade groups to New Guinea.
Dumont d'Urville in 1838 continued the survey.
C. Dumont d'Urville had seen its skin, which the naturalists of his expedition procured, worn as a tippet by a Maori chief at Tolaga Bay (Houa-houa), 2 and in 1830 gave what proves to be on the whole very accurate information concerning it (Voy.
55° S.) the ship reached Adelie Land, discovered by D'Urville in 1840, and effected a landing in Commonwealth Bay, the position of which was subsequently fixed by wireless time-signals as lat.
