The appointed time for our return to New Archangel now approached. Our vessel had been fully prepared for encountering the violent and continued storms of the North, and I waited the return of our mineralogist, M. Hoffman, who had gone to O Wahi, for the purpose of climbing the mountain Mou-na-roa, in which however he did not succeed. By command of Queen Nomahanna, assistance had indeed been afforded him; but the two Kanackas, who accompanied him as guides, refused to proceed farther than seven thousand feet above the level of the sea, or about half-way up the mountain; a height to which the most courageous O Wahian will scarcely venture, from fear partly of the spirits which haunt the summit of the mountain, partly of the cold, which is almost too severe for an inhabitant of the tropics to endure. At this point the Kanackas threw themselves flat upon the earth, nor would they stir another step, although certain of punishment for their refusal. In vain M. Hoffman tried to shake their resolution, first by offering them large presents, and then by threatening them with a loaded pistol; they were immoveable, and he was forced to return. His expedition, however, was not altogether fruitless: besides his mineralogical observations, he discovered an extraordinary cave, running at an acute angle several hundred feet deep into the mountain, where he found a sheet of water, which stretched as far as the light of the torches permitted the light to reach through the fearful darkness. It would have been interesting to have traversed this subterranean sea in a boat. It is most remarkable, that the water of this lake is salt, and that the alternate ebb and flow of the tide is as perceptible here as on the coast. M. Hoffman will probably publish other particulars respecting this natural curiosity.
