Cowries were at one time imported into England in considerable quantities for use in the African slave-trade. "For this purpose," says Milburn, "they should be small, clean, and white, with a beautiful gloss" (i. 273). The duty on this importation was £53, 16s. 3d. per cent. on the sale value, with ⅓ added for war-tax. In 1803, 1418 cwt. were sold at the E. I. auctions, fetching £3,626; but after that few were sold at all. In the height of slave-trade, the great mart for cowries was at Amsterdam, where there were spacious warehouses for them (see the Voyage, &c., quoted 1747).
c. A.D. 943.—"Trading affairs are carried on with cowries (al-wada'), which are the money of the country."—Maṣ'ūdī, i. 385.
c. 1020.—"These isles are divided into two classes, according to the nature of their chief products. The one are called Dewa-Kauḍha, 'the Isles of the Cowries,' because of the Cowries that they collect on the branches of coco-trees planted in the sea."—Albirūnī, in J. As., Ser. IV. tom. iv. 266.
c. 1240.—"It has been narrated on this wise that as in that country (Bengal), the kauṛi [shell] is current in place of silver, the least gift he used to bestow was a lak of kauṛis. The Almighty mitigate his punishment [in hell]!"—Ṭabaḳāt-i-Nāṣiri, by Raverty, 555 seq.
c. 1350.—"The money of the Islanders (of the Maldives) consists of cowries (al-wada'). They so style creatures which they collect in the sea, and bury in holes dug on the shore. The flesh wastes away, and only a white shell remains. 100 of these shells are called siyāh, and 700 fāl; 12,000 they call kutta; and 100,000 bustū. Bargains are made with these cowries at the rate of 4 bustū for a gold dīnār. [This would be about 40,000 for a rupee.] Sometimes the rate falls, and 12 bustū are exchanged for a gold dīnār. The islanders barter them to the people of Bengal for rice, for they also form the currency in use in that country.... These cowries serve also for barter with the negroes in their own land. I have seen them sold at Mālī and Gūgū [on the Niger] at the rate of 1150 for a gold dīnār."—Ibn Batuta, iv. 122.
c. 1420.—"A man on whom I could rely assured me that he saw the people of one of the chief towns of the Said employ as currency, in the purchase of low-priced articles of provision, kaudas, which in Egypt are known as wada, just as people in Egypt use fals."—Makrizi, S. de Sacy, Chrest. Arabe, 2nd ed. i. 252.
[1510.—Mr. Whiteway writes: "In an abstract of an unpublished letter of Alboquerque which was written about 1510, and abstracted in the following year, occurs this sentence:—'The merchandize which they carry from Cairo consists of snails (caracoes) of the Twelve Thousand Islands.' He is speaking of the internal caravan-trade of Africa, and these snails must be cowries.">[
1554.—At the Maldives: "Cowries 12,000 make one cota; and 4½ cotas of average size weigh one quintal; the big ones something more."—A. Nunes, 35.
" "In these isles ... are certain white little shells which they call cauris."—Castanheda, iv. 7.
1561.—"Which vessels (Gundras, or palm-wood boats from the Maldives) come loaded with coir and caury, which are certain little white shells found among the Islands in such abundance that whole vessels are laden with them, and which make a great trade in Bengala, where they are current as money."—Correa, I. i. 341.
