In the Gulf of Siam on the Asiatic coast, pearls are obtained from a small oyster with a thin shell, presumably a variety of the Lingah oyster. The beds have not yet been thoroughly exploited, as the Siamese do not especially value pearls, attributing some superstitious sentiments of ill luck to them. However, from time to time Chinese traders have bought them from the Malay divers and sold them at great profit in the Singapore market. The known beds occur chiefly in the northern part of the gulf, on the west coast, and extend in a narrow belt for a distance of about one hundred miles. The fishing is prosecuted by nude divers in shallow water. A recent letter from Dr. K. Van Dort, a mining engineer of Bangkok, Siam, states that in 1906 in six weeks, with the aid of half a dozen divers he was able to collect 720 grains’ weight of pearls, mostly small ones, but including one of 20 grains, one of 14 grains, two of 12 grains each, and seven over 9 grains in weight. He reports that the total value of the large ones in Bangkok was $1500, but the small ones could not be sold to any advantage, as they are little prized by the Siamese. The shells are of no commercial value, as they are too thin for industrial use other than for inlaid work. Some fine old specimens of marquetry in which these shells were used exist in the Buddhist temples at Bangkok. This art of inlaying is almost lost among the Siamese, and there is said to be only one man in the king’s palace who can lay any claims to proficiency in working mother-of-pearl shell.

EAST AFRICAN PEARL FISHERIES
The Islanders with fleecy curls,
Whose homes are compass’d by the Arabian waves;
By whom those shells which breed the orient pearls
Are dived and fish’d for in their green sea caves.
The principal pearl fisheries of the coasts of Africa are those prosecuted in the Red Sea, between this continent and Asia. These have already been described in the preceding chapter, among the Asiatic fisheries; for, although situated between the two continents, they are prosecuted largely by Arabs rather than by natives of the western shores of the sea.
