Shakspere may have had in view some such scene as this when he spoke of the “pearl in your foul oyster.” The lady who cherishes and adorns herself with a necklace of Ceylon pearls would be horrified were she to see and especially to smell the putrid mass from which her lustrous gems are evolved. The great quantity of repulsive bluebottle flies are so essential to success in releasing the pearls from the flesh, that a scarcity of them is looked upon as a misfortune to the merchants. However, except it may be at the beginning of a fishery, there is rarely ever a cause for complaint on this score, for commonly they are so numerous as to be a great plague to persons unaccustomed to them, covering everything, and rendering eating and drinking a difficult and unpleasant necessity, until darkness puts a stop to their activities. But the intolerable stench, impossible of description, the quintessence of millions of rotting oysters, fills the place, and makes existence a burden to those who have not acquired odor-proof nostrils. This animal decomposition seems almost harmless to health; indeed, the natives evidently thrive on it, and eat and sleep without apparent notice of the nauseous conditions. And yet vegetable decomposition in this region is usually followed by fatal results. Notwithstanding sanitary precautions and the usual quarantine camp and hospitals, cholera occasionally becomes epidemic and puts a stop to the fishery, as was the case in 1889; but this probably was due more to the violation of ordinary sanitary laws than to the decaying oysters. In a large _toddi_ the oysters are placed in a _ballam_, or a dug-out tank or trough, fifteen or twenty feet long and two or three feet deep, smooth on the inside so that pearls may not lodge in the crevices. This tank is covered with matting, and the _toddi_ is closed up, sealed, and guarded for a week or ten days, when the fly maggots will have consumed practically all of the flesh tissues, leaving little else than the shells and pearls. The tank is then filled with sea water to float out the myriads of maggots. Several nude coolies squat along the sides to wash and remove the shells. The valves of each shell are separated, the outsides rubbed together to remove all lodgments for pearls, and the interior examined for attached or encysted pearls. The washers are kept under constant supervision by inspectors to prevent concealment of pearls; they are not permitted to remove their hands from the water except to take out the shells, and under no circumstances are they allowed to carry the hands to the mouth or to any other place in which pearls could be concealed.
