A curious fishery, with the _Placuna placenta_ for its object, exists in Tablegram Lake, a small bay in northeastern Ceylon adjacent to the magnificent harbor of Trincomali, which Nelson declared to be “the finest in the world.” At intervals during the nineteenth century, the Ceylon government leased the Tablegram Lake fishery to native bidders for a period of three consecutive years. In 1857, Dr. Kelaart visited the place and calculated that in the three years preceding, eighteen million oysters had been removed.[161] Owing to scarcity of the mollusk, no fisheries have existed since 1890, but from 1882 to 1890 they were regularly leased at an average of Rs.5000 for each term of three years. Prof. James Hornell, who made a careful examination in 1905, reported that if the business were carried on providently and systematically, “it should become the source of a fairly regular annual revenue to Government of from Rs.10,000 to Rs.12,000, possibly even more.”[162] The _Placuna_ oysters are caught by Moormen divers, who are scarcely equal physically to the pearl fishery in the sea. They rarely descend more than four fathoms, and most of the work in Tablegram Bay is in less than two fathoms. Each diver returns with from one to five or more oysters, depending on their abundance, and receives one half of the catch as his share of the proceeds. Unlike the method in the pearl-oyster fishery of Ceylon, the _Placuna_ oysters are opened while fresh, this work being performed by coolies, who are compensated at the rate of about Rs.3 per 1000. THE PEARL FISHERIES OF INDIA There are two moments in a diver’s life: One, when a beggar, he prepares to plunge; Then, when a prince, he rises with his prize. ROBERT BROWNING. Notwithstanding the great fame of the pearl fisheries of India, those prosecuted within the limits of British India proper are of small extent. The only pearl resources within the empire are the rarely productive reefs on the Madras coast in the vicinity of Tuticorin, the relatively modern fisheries of Mergui Archipelago, and some small reefs of only local importance on the Malabar coast and in the Bombay presidency. The celebrity of India in connection with the pearl fisheries has never rested on the extent of those within the territorial limits or under the control of this government. It originated in the fact that it is largely Indian capital which finances the fisheries of Ceylon and of the Persian Gulf; nearly all of the divers and others employed in Ceylon are from the coast of this empire, and most of the pearls are purchased by merchants of Bombay, Madura, Trichinopoli, and other large towns. Thus, from an economic and industrial point of view, the pearl fisheries of Ceylon, and to a less extent those of the Persian Gulf, have contributed to the fame and to the wealth of the Empire of India.
