In an administrative sense the important building is the "Kachcherie"--mayor's office and superintendent's headquarters in one; but the structure of material interest is the "kottu," wherein every sackful of oysters taken from the boats is counted and apportioned between the government and the divers. It is a parallelogram enclosure of two or three acres in area, fenced with bamboo palings, and roofed here and there to protect the coolies from the sun. For convenience, one end is as near the sea as prudence will admit; and the other, the official end, where accountants and armed guards are in command, is not far from the governmental offices. A system perfected by years of experience makes thieving within the kottu virtually impossible, and the clerks who record the count of oysters, and issue them upon official order, might safely conduct a bankers' clearinghouse. On occasions they handle without error more than three million oysters in a day. A quarter of a mile from the official section of the city is the great human warren and business region, where black men and brown--Hindus, Mohammedans, Buddhists, and the East's flotsam of religions--dwell and traffic in peaceful communion. A broad thoroughfare, starting from the edge of the plateau overlooking the sea and extending inland until the settlement yields to the open country, is the "Main street"; and here, for ten or twelve weeks, is one of Asia's busiest marts. This part of Marichchikkaddi is planned with careful regard for sanitary needs and hygiene. Streets cross at right angles, and at every corner stands a lamp-post rudely made from jungle wood, from which suspends a lantern ingeniously fashioned from an American petroleum tin. Sites on the principal streets are leased for the period of the fishery to persons proving their purposes to be legitimate. For a good corner lot perhaps twenty feet square the government receives as much as a thousand rupees; and a few hours after the lease is signed up goes a cadjan structure--and a day later pearls worth a king's ransom may there be dealt in with an absence of concern astounding to a visitor.
