On the southeast coast of Arabia, pearl fishermen are to be found at the various harbors from Aden to Muscat. Their fantastic dhows are met with in the harbor of Makalla, and also in that of Shehr. On the Oman coast, the ports of Sur and of sun-scorched Muscat do a considerable pearling business, not only locally but to the Sokotra Islands, and even on the coast of East Africa and Zanzibar, the trading baggalas adding pearling and illicit slave-trading to their many sources of income. A number of these traders, each with an instinct for pearls equal to that of a trained hound for game, visit the fishing centers at intervals, and exchange needful commodities for pearls and shells. The Arab pearl-divers of the Red Sea have been noted for the depths to which they can descend. Lieutenant J. R. Wellsted, of the Indian Navy, who had unusual facilities for acquaintance with their exploits, reported that in the Persian Gulf the fishermen rarely descended beyond eleven or twelve fathoms, and even then they exhibited signs of exhaustion; but that in the Red Sea they go down twice that depth. Among the most noted of these divers of the last century was old Serúr, who attracted the notice of many travelers. Lieutenant Wellsted states that he saw him descend repeatedly to twenty-five fathoms without the slightest evidence of distress; that he frequently dived in thirty fathoms, and is reported to have brought up mud from the bottom at a depth of thirty-five fathoms, which is about the record, the pressure of the water being nearly 90 pounds to the square inch. His sons were also remarkably expert; one of them when scarcely thirteen years of age would descend to a depth of twenty-five fathoms.[168] [Illustration: CARVED “JERUSALEM SHELL” FROM THE RED SEA In the collection of Dr. Bashford Dean ] An interesting story of an Arab’s diving ability is told by Lieutenant Wellsted: “In 1827, we were cruising in the sloop _Ternate_ on the pearl banks. Whilst becalmed and drifting slowly along with the current, several of the officers and men were looking over the side at our Arab pilot, who had been amusing himself in diving for oysters. After several attempts, his search proved unsuccessful. ‘Since I cannot get oysters I will now,’ said he, ‘dive for and catch fish.’ All ridiculed the idea. He went down again, and great was our astonishment to see him, after a short time, rise to the surface with a small rock-fish in each hand. His own explanation of the feat was, that as he seated himself at the bottom, the fish came around and nibbled at his skin. Watching his opportunity, he seized and secured his prey by thrusting his thumb and forefinger into their expanded gills.”[169]
