III. Islands of Santa Cruz. — In my Memoir, belonging to the 
chart of these islands, I have discussed the situation of Carteret's 
Sivallow Island, and expressed my belief that the islands seen by 
Captain Wilson in 1797 are the same as Swallow Island. Captain 
Freycinet is of the same opinion, and, by a new survey of Wilson's 
Island, confirmed this hypothesis. There remains, then, no doubt 
that Byron's Swallow Island does not exist ; but, as it still continues 
to be delineated on some of the latest charts, it would be well that its 
non-existence should be equally proved by the American Expedition. 
IV. The Solomon Islands. — These islands have partly been visited 
by D'Urville and Shortland, partly by D'Entrecasteaux; and several 
English ships have at different times sailed through them; but a 
complete survey of all the islands composing this great archipelago is 
still wanting. It is indeed very singular that, of all the navigators 
who have lately visited the Pacific Ocean, none have ever attempted 
any thing like a systematic survey of these islands, with the 
exception of D'Entrecasteaux, who, at least, sailed along the southern 
islands from east to west, and thus greatly improved the hydrography 
of them. I have published, in the year 1827, a chart of these 
islands: (Carte Systematique de l'Archipel des Isles Salomon.) 
Having collected all the materials that were to be had at that time, 
many of them in apparent contradiction to each other, I endeavoured 
to reconcile them, and to delineate the lands belonging to this archi- 
pelago, to the best of my judgment. (An account of my proceedings 
will be found in the Memoir accompanying my chart.) By the first 
survey of these islands, it will be seen whether some of my combina- 
tions have been well founded or not. The Solomon Islands being 
the greatest archipelago in the Pacific Ocean, and the least known, 
deserve, no doubt, to be as completely surveyed as the Society, 
Friendly, or other groups. Although ten years have elapsed since 
my chart was published, nothing has been done since that time for 
the hydrography of these islands, to enable me to improve the second 
edition of that chart, (1836,) except in the situation of a group of 
islands, discovered lately, to the northward of the Solomon Islands. 
V. New Caledonia, — A dangerous reef has lately been discovered 
by the ship Petrie, to the northward of New Caledonia ; the precise 
position of this danger ought to be determined. 
VI. Loyalty Islands. — Captain D'Urville has been the first to survey 
the Loyalty Islands ; but having sailed only along the northern side of 
them, it is to be wished that the southern shore might also be surveyed.
