Owing to the character of the fishery and the lack of government supervision, it is extremely difficult to determine accurately the extent of this industry in the Red Sea and the Arabian Gulf. All over this coast extends the influence of the Hindu traders, who finance the fisheries and purchase most of the catch. The pearls are sent mostly to Bombay, and are not reported in the official returns of the Red Sea ports. The fishermen are suspicious of outside inquiries, and are far from anxious to impart reliable information. Probably the best estimates of the catch are to be obtained from Bombay merchants, from whom A. Perazzoli learned in 1898 that pearls to the value of 2,000,000 lire ($400,000) were carried from the Red Sea to Bombay each year.[170] In the last four or five years the output has been smaller than usual, owing to disturbed political conditions. The annual product of “Egyptian” and “Bombay” shells in these fisheries is usually upward of 1000 tons, worth from $100 to $600 per ton, according to quality. Most of these go to Austria and France, only about 200 tons reaching London each year. Owing to the dark color and the lack of thickness in the nacreous layer, they are scarcely suitable for anything else than button manufacture. Many of them are sent to Bethlehem and Jerusalem, where they are cut into various shapes for crosses, crucifixes, wafer-boxes, beads, and nearly every conceivable article in which mother-of-pearl is manufactured. Many of the choicest shells are incised with scriptural or allegorical designs for sale to tourists as well as for export. The best of the engraved shells sell for $10 to $50, and the cheaper ones for less than $1 each. This industry is of great importance in Bethlehem, giving employment to a considerable percentage of the eight thousand inhabitants of the village. Doubtless in no pearl fishery in the world are greater hardships endured than in the Red Sea and along the coast of the Arabian Gulf. In practically every other region, the industry is carried on under government supervision, and there is little opportunity for ill-treatment of the humbler fishermen. But the fanatics who control the fishery on the Arabian coast—untrammeled by authorities and responsible to none—show little consideration for the poor divers, and particularly for the unfortunate black slaves brought from the coast of Africa. These pearl fishermen lead a very eventful life, the divers especially. They see some wonderful sights down below the surface-plant life and creeping things and enemies innumerable. Dropping from the sun-scorched surface down into the deep cool waters, everything shows “a sea change, into something rich and strange,” just as the eyes of the drowned man in Ariel’s song are turned into pearls and his bones into coral.
