It is during the calm period of the northeast monsoon,--February, March and April,--when the sea is flat and the sky is bright and unflecked, that the fishery is carried on. The line of banks--they are "paars," in the languages of Ceylon--cover an extensive submarine plateau off the island's northwest coast, from ancient Hippuros southward to Negombo. This is of flat-surface rock, irregularly carpeted with coarse sand, and dotted with colonies of millions of oysters. Dead coral and other products of the sea are scattered everywhere on this plateau, and it is a theory that these surface interruptions prevent overcrowding of the oysters, and consequently assist in the bivalve's reaching the pearl-producing stage. It is claimed that a crowded paar contributes to a stunting of growth, bringing disease and premature death to the oyster, and consequently no pearls of account. The estimate of the experts upon which it was decided to announce a fishery last year was that there were on the Southwest Cheval paar 3,500,000 oysters which might be gathered, on the Mideast Cheval paar 13,750,000 oysters, on the North and South Moderagam 25,750,000, and on the South Cheval 40,220,000. The announcement of this total of 83,000,000 bivalves produced an electrical effect, and an unprecedented attendance, for it was equal to announcing a lottery with that many tickets, and who knows how few prizes! The student seeking to determine the eighth wonder of the world should not overlook the city of Marichchikkaddi. Stories of towns rising overnight wherever gold is found, or diamonds discovered, or oil struck, have become common to the point of triteness. Tales of the uprising of Klondike and South African cities, once amazing, fade to paltriness in the opinion of one who has seen the teeming city of Marichchikkaddi. In a sense it is a capital, yet it is found in no geography; no railway connects it with the world, yet a dozen languages are spoken in its streets. Marichchikkaddi's population numbers no young children, no persons too aged to toil, and the four or five hundred women sojourners merit the right of being present through serving as water-carriers to camp and fishing fleet. [Illustration: COOLIES CARRYING PEARL OYSTERS FROM THE BOATS TO THE "KOTTU," OR GOVERNMENT STOCKADE] This place with double-mouthful name, almost defying pronunciation, is the pearl metropolis of the universe. Probably there is not a stocked jewel-case that does not contain gems that have been filtered through this unique city by the sea. For a dozen reasons it is a wonderful town, and the foremost of these is that it is the only city of size that comes and goes like the tide's ebbing and flowing.
