In preparing for descent, the fisherman takes hold of the rope from which the diving stone is suspended, puts one foot in the loop just above the stone and places the other foot in the rim of a net basket, eighteen inches wide, made of coir rope. When ready, he signals his attendant, inhales several good breaths, closes his nostrils with a _fitaam_ or nostril-clasp of flexible horn attached to a cord around his neck, raises his body somewhat above the surface to give force to the descent, releases the slip-knot retaining the stone, and sinks rapidly to the bottom. Immediately disengaging his foot from the stone, he throws himself in a stooping position on the ground and collects as many oysters as possible during the fifty seconds or more in which he is able to remain under water. When near his limit of endurance, he hastily gives a signal jerk to the rope attached to the basket, and the watchful attendant hauls him up as speedily as possible, the diver frequently quickening the ascent by hand over hand movement up the rope. When near the surface, he lets go of the rope and with his arms close to his body pops above the surface puffing and blowing. The contents of the net bag are emptied into a large basket by the attendant, and the dead shells and other refuse are separated from the live oysters and thrown back into the sea, the diver having worked too rapidly at the bottom to discriminate closely as to what he gathered. In the meantime, the stone has been drawn up and suspended by the slip-knot in its customary position and the diving partner is resting at the surface preparatory to descending. Thus, diving alternately at intervals of five or six minutes, each fisherman descends thirty or forty times in an ordinary day’s work. The number of oysters gathered at each descent depends on such conditions as their abundance, the depth and clearness of the water, etc. It ranges from none to fifty or more, but ordinarily ten or twelve is a good average. As the men commonly work on shares, the shells brought up by each diver or by each pair of divers are kept separate. The best type of Arab divers are very careful of themselves, drying the body thoroughly with towels on coming out of the water, taking intervals of rest during the day’s work; and even while in the water between dives they may enjoy the luxury of a cheroot or pipe, or possibly a cigarette may pass from mouth to mouth of several men. When pursuing their work, the divers are abstemious. After devotions at sunrise and a light breakfast of perhaps dates or rice and coffee, they begin fishing. About noon they knock off for coffee, prayers, and an hour’s siesta, and then resume work for several hours. When the day’s work is over and they have faced Meccaward with the customary prayers, they rest and eat a substantial meal, commonly of dates and fish roasted over a charcoal fire.
