pearl

Before the beginning of the 20th century, the only means of obtaining pearls was by manually gathering very large numbers of pearl oysters or mussels from the ocean floor or lake or river bottom. The bivalves were then brought to the surface, opened, and the tissues searched. More than a ton were searched in order to find at least 3-4 quality beads.[citation needed] In order to find enough pearl oysters, free-divers were often forced to descend to depths of over 100 feet on a single breath, exposing them to the dangers of hostile creatures, waves, eye damage, and drowning, often as a result of shallow water blackout on resurfacing.[2] Because of the difficulty of diving and the unpredictable nature of natural pearl growth in pearl oysters, pearls of the time were extremely rare and of varying quality. Although harvesting of shells had long been practiced by Aboriginal Australians, pearl diving only began in the 1850s off the coast of Western Australia and the pearling industry remained strong until the advent of World War I, when the price of mother-of-pearl plummeted with the invention and expanded use of plastics for buttons and other articles previously been made of shell. In the 1870s pearling began in the Torres Strait, off Far North Queensland. By the 1890s, pearling was the largest industry in the region, and had a huge impact on coastal Aboriginal Australians and Torres Strait Islander peoples. Because of the dangers of diving, almost no white people participated, and Asian, Pacific, and Indigenous Australians were used as cheap labor for the industry. Shells were the main aim for collection, and the whole industry was essentially a colonial one geared to procuring mother-of-pearl for sale to overseas markets for the making of buttons. As time went on and sources were depleted, divers were encouraged to dive deeper, making the enterprise even more dangerous. Divers experimented with the heavy diving suit, discarding the full diving suit and using the helmet and corselet only, which became standard practice until 1960. "Hookah" gear, tested to 48 fathoms (87 meters) in 1922, was considered unsuitable for the strong tides in these waters, and the later Scuba equipment did not supply enough air to spend the time required underwater and for decompression, while surfacing [10] Source: en.wikipedia.org/wiki/Pearl_hunting

Pearling has been carried out in Indonesian waters from very early times, with local divers collecting the shell. Some of the Indonesian divers went a con-siderable distance in search of shell. As Europeans extended their presence in the north of Australia, they saw Indonesians collecting pearls in Australian waters. The Aru Islands have been, and still are, one of the principal pearl-shell grounds in Indonesia. Al-though quite off the track of all European trade, these islands had by the early 19th century become the eastern terminus for the annual fleet of Bugis prahus from Ma-kassar (The Buginese are traders and seaborne colonists from south Sulawesi; see map, Fig. 2.) They were a source not only of pearls and mother-of-pearl, hut of such exotics as birds of paradise, tortoiseshell, trepang or sea slug, and edible birds’ nests. The British naturalist Alfred Wallace did the 1000-mile journey to the remote islands in a Bugis prahu in the 1850s (Fig. 4) and considered it quite an achieve-ment. “Even by the Makassar people themselves the voyage to the Aru Islands is looked upon as a rather wild and romantic expedi-tion, full of novel sights and strange adventures. He who has made it is looked up to as an authority, and it remains with many the unachieved ambition of their lives. I myself had hoped rather than expected ever to reach this “Ultima Thule” of the East…” (Wallace 1869:309). Source: www.penn.museum/sites/expedition/sampans-belangs-and-junkos/
