In the valuation of ani, anitari and vadivu, the individual size, form, and color is considered, but the others are simply valued by weight.

The modus operandi of these fisheries like all others managed by Orientals continues much the same from fishing to fishing. Experiments have been made at the Tuticorin fishery with helmeted divers but their catch compared unfavorably with that of the naked natives, who will sometimes under favorable circumstances bring up two thousand in a day. It is said that the X-ray is being used to some extent in the examination of shells and that those found to be without pearls are thrown back into the sea, but it is doubtful if the general use would be practical or advantageous while oysters remain abundant; so far, the use of it has been experimental only.

Fine pearls are found in Dutch India among the Molucca Islands. Fishing is done by the natives, and as they seldom go deeper than ten or twelve feet the probability is that they do not get the finest shells or pearls, for it seems to be quite well established that the shells taken from deep water are larger and more likely to contain large pearls. Whether this arises from deep water being more favorable to growth, or an unmolested opportunity to grow, has not been determined.

Hitherto the Netherlands Indian government has opposed encroachment upon the rights of the natives and colonists, and has patrolled the waters with small gunboats to prevent any attempt by Europeans to fish. But lately concessions have been made to British firms so that shell is being shipped direct to London, and it is now thought that these fisheries will soon rival the Australian. The pearls were formerly bought from natives, principally of the Island of Aroe, by Chinese and Arabs who took them to Macassar. From there they were sent first to Singapore and then to London, Paris, and Amsterdam. Most of the pearls brought to Macassar are baroques, though fine specimens of more regular shape arrive there occasionally. The mother-of-pearl from these shells is of good quality.

Some pearls are found at the Bazaruto Islands, Portuguese East Africa, a few miles from the coast, midway between Inhambane and Beira. A concession was granted to a company about 1892, but bad management, lack of funds and political difficulties, killed the enterprise.

General reports indicate that it is very difficult for any enterprise subject to the officials of this district to succeed. The Bazaruto Kaffirs still fish, but without system or intelligence. They are wasteful and damage many of the pearls by cooking the oyster. The few found are shipped by Indian traders to Bombay and Zanzibar.

Pearl fishing has been attempted on the coast of German East Africa at Zanzibar Island and south, between the Island of Mafia and the main coast. Mother-of-pearl is abundant but few pearls have been found and there has been no sustained effort. There are large coral banks about the islands of the coast favorable for the growth of mother-of-pearl and there is shallow water over large areas.

Good white pearls have been taken from a red mussel found there. South of the Island of Mafia are beds of large pinna shells which yield black seed-pearls. There are pearl-shell fisheries in the Merguian Archipelago and in the government of Burmah and some pearls are found. The banks, scattered over an area of eleven thousand square miles, are rented from the government and rights to fish are sublet on royalty. The fishing is nearly all done by helmeted divers.

Avicula and meleagrina margaritifera are taken off the west coast of New Caledonia. From the former large numbers of pearls are taken, and from the latter, very beautiful white pearls. Fine colored pearls pink, yellow, gray and black are often found in this district. A variety of oyster commonly called shoulder of mutton, and another shell-fish called jamboneau (pinna) of which the pearl is very fine, are also found in these waters.

A syndicate was formed in Paris to exploit these beds and obtained concessions covering one hundred and thirty miles. Owing to the difficulty of getting divers, the waters had not been exploited to any great depth up to 1898, the regular fishings being confined to the shallows of six to seven feet, though larger shells were known to be in deeper water. More systematic work with modern appliances and in deeper waters has since been done with good success, but late reports show an accumulation of shell and indications that the industry has not been profitable.
