This bag is for holding any oysters which he may gather, and its rope is for hauling the diver back to the surface. Prior to descending the divers put on leather finger stalls to protect their fingers whilst plucking the oysters from the coral reefs or rocks, and fix leather clips to their noses. Divers do not 'dive' in the normal sense, they go feet first, standing on the stone weight, which allows them to step off on reaching the sea-bed. There they gather as many oysters as they can in the short space of time during which their lungs can function without fresh air.

They also have to contend with their natural enemies such as starfish, borers, rays, etc. Rays play an important part in the cycle of parasitic intrusion and infestation of the oyster which causes pearl formation; this seems a bizarre example of nature's handiwork. When one considers the hazards of tides, temperatures, winds, currents, disease and predators, together with the peculiar cycle of parasitic infestation, plus haphazard fertilization and many other permutations of chance, the arrival of a perfectly spherical umblemished pearl of cream rosee hue is a near miracle.
