In 1897, rich beds of pearl-oysters were discovered off the west coast of this island. They are most numerous between the shore and the barrier reefs on the west coast from Pouembout River to Gomen Bay, and especially about the small island of Konienne at the mouth of the Pouembout River. They are also abundant among the Loyalty Islands off the eastern coast of New Caledonia, and especially at the island of Lifu.[243] The shell is similar to that from Torres Straits, and the yield of pearls is very large. Several concessions have been obtained to exploit these beds, one of them covering 130 miles in length. The industry is carried on by means of scaphanders, in a manner similar to that of Torres Straits. Virtually all of the catch is sent to France. The natives of the South Sea Islands, and particularly of Penrhyn and the Tuamotu group, are doubtless the most expert divers in the world. This can be readily appreciated by those who have read of Hua Manu in C. W. Stoddard’s thrilling narrative, or have heard the story of the brown woman who swam for forty hours in a storm with a helpless husband on her back. Accustomed to the water from infancy, these human otters swim all day long as readily as they would walk, go miles from shore without a boat in search of fish which they take by means of baited hook and line, and boldly attack a shark single-handed. Seemingly fabulous stories are told of their descending, unaided, 150 feet or more beneath the surface, and remaining at lesser depths for nearly three minutes, far surpassing any modern records of the divers of India. The water in the South Seas is wonderfully clear, enabling the fishermen to detect small objects at considerable depths, and especially so when using the water-telescope, similar to that employed in the Red Sea fisheries. By immersing this to a depth of several inches and cutting off the light from the upper end as he gazes through it down into the waters, the fisherman can readily inspect the bottom at a depth of fifteen fathoms, and thus locate the shells before he descends.
