The pearl oyster is found in all the waters from Ras Mussendom to the head of the Gulf, but on the Persian side there are no known banks of value. They vary in distance from one to ninety miles from the low-lying shore of 'Araby the Blest,' but the deep sea banks are not so much fished till the 'Shemal' or nor'westers of June have spent their force. The three seasons for fishing are known as 'the spring fishing' in the shallow water, 'the summer fishing' in the deep waters, and 'the winter fishing' conducted principally by wading in the shoals. The pearls of these seas are still celebrated for their firmness, and do not peel. They are commonly reported to lose one per cent. annually for fifty years in colour and water, but after that they remain the same. They have seven skins, whereas the Cingalese pearls have only six. The merchants generally buy them wholesale by the old Portuguese weight of the _chao_. They divide them into different sizes with sieves and sell them in India, so that, as is usually the case with specialties, it is impossible to buy a good pearl on Bahrein. Diving here is exceedingly primitive; all the necessary paraphernalia consists of a loop of rope and a stone to go down with, a curious horn thing to hold the nose, and oil for the orifice of the ears. Once a merchant brought with him a diving apparatus, but the divers were highly indignant, and leaguing against him refused to show the best banks. In this way the fisheries suffer, for the best pearls are in the deeper waters, which can only be visited late in the season. The divers are mostly negro slaves from Africa; they do not live long, poor creatures, developing awful sores and weak eyes, and they live and die entirely without medical aid. At present the pearl-fisheries employ about four hundred boats of from eight to twenty men each. Each boat pays a tax to the sheikh. The fishing season lasts from April to October. Very curious boats ply in the waters between Manamah and Moharek; the huge ungainly baggalas can only sail in the deeper channels. The Bahrein boats have very long-pointed prows, elegantly carved and decorated with shells; when the wind is contrary they are propelled by poles or paddles, consisting of boards of any shape tied to the end of the poles with twine, and the oarsman always seats himself on the gunwale. Perhaps the way these boats are tied and sewn together may have given rise to the legend alluded to by Sir John Maundeville when he saw them at the Isle of Hormuz. 'Near that isle there are ships without nails of iron or bonds, on account of the rocks of adamants (loadstones), for they are all abundant there in that sea that it is marvellous to speak of, and if a ship passed there that had iron bonds or iron nails it would perish, for the adamant, by its nature, draws iron to it, and so it would draw the ship that it should never depart from it.'
