The expedition next sent out under the command of Captain Dumont d'Urville was merely intended by the minister to supplement and consolidate the mass of scientific data collected by Captain Duperrey in his voyage from 1822 to 1824. As second in command to Duperrey, and the originator and organizer of the new exploring expedition, D'Urville had the very first claim to be appointed to its command. The portions of Oceania he proposed to visit were New Zealand, the Fiji Islands, the Loyalty Islands, New Britain, and New Guinea, all of which he considered urgently to demand the consideration alike of the geographer and the traveller. What he effected in this direction we shall ascertain by following him step by step. An interest of another character also attaches to this trip, but it will be well to quote on this point the instructions given to the navigator. "An American captain," writes the Minister of Marine, "said that he saw in the hands of the natives of an isle situated between New Caledonia and the Louisiade Archipelago a cross of St. Louis and some medals, which he imagined to be relics of the wrecked vessel of the celebrated La Perouse, whose loss is so deeply and justly regretted. This is, of course, but a feeble reason for hoping that some of the victims of the disaster still survive; but you, sir, will give great satisfaction to his Majesty, if you are the means of restoring any one of the poor shipwrecked mariners to their native land after so many years of misery and exile." The aims of the expedition were therefore manifold, and by the greatest chance it was able to achieve them nearly all. D'Urville received his appointment in December, 1825, and was permitted himself to choose all who were to accompany him. He named as second in command Lieutenant Jacquinot, and as scientific colloborateurs Messrs. Quoy and Gaimard, who had been on board the _Uranie_, and as surgeon Primevere Lesson. The _Coquille_, the excellent qualities of which were well known to D'Urville, was the vessel selected; and the commander having named her the _Astrolabe_ in memory of La Perouse, embarked in her a crew of twenty-four men. Anchor was weighed on the 25th April, and the mountains of Toulon with the coast of France were soon out of sight. After touching at Gibraltar, the _Astrolabe_ stopped at Teneriffe to take in fresh provisions before crossing the Atlantic, and D'Urville took advantage of this delay to ascend the peak, accompanied by Messrs. Quoy, Gaimard, and several officers, a bad road, very arduous for pedestrians, leading the first part of the way over fields of scoria, though as Laguna is approached the scenery improves. This town, of a considerable size, contains but a small, indolent, and miserable population.
