Vegemite is made from the spent yeast left over from the fermentation of beer. Can it be recycled to produce Vegemite beer, and how does it taste? 28 Does Culling Work?

    terra australis 30 Terra Australis reports the results of archaeological and related research within the south and east of Asia, though mainly Australia, New Guinea and island Melanesia — lands that remained terra australis incognita to generations of prehistorians. Its subject is the settlement of the diverse environments in this isolated quarter of the globe by peoples who have maintained their discrete and traditional ways of life into the recent recorded or remembered past and at times into the observable present. Since the beginning of the series, the basic colour on the spine and cover has distinguished the regional distribution of topics as follows: ochre for Australia, green for New Guinea, red for South-East Asia and blue for the Pacific Islands. From 2001, issues with a gold spine will include conference proceedings, edited papers and monographs which in topic or desired format do not fit easily within the original arrangements.

  • (Coryphaena Hippurus)Exploitation in Japan, East Asia, and the Pacific
    7 The History and Culture of Dolphinfish (Coryphaena hippurus) Exploitation in Japan, East Asia, and the Pacific Hashimura Osamu, Tokyo Gakugei University, Faculty of Education, Japan Introduction What is the history behind human exploitation of dolphinfish (Coryphaena hippurus), and why were they so sought after by groups in the Pacific over such long periods of time (Figure 1)? The purpose of this paper is to examine the relationships between humans and dolphinfish, a highly migratory species that requires trolling technologies in order to catch. Figure 1. Dolphin fish Coryphaena( hippurus). Source: Photo by the author. 142 Prehistoric Marine Resource Use in the Indo-Pacific Regions Research Background The Japanese Archipelago is situated along the northwestern Pacific Rim, at the juncture where numerous species of migratory fish pass through nearby waters. In total, there are 350 species of endemic fish and two types of migratory fish. These include: 1) fish found in the warm Kuroshio Current, such as tuna, bonito, yellowtail, Spanish mackerel, sword fish, dolphinfish, and flying fish; and 2) fish found in the cold Oyashio Current, such as saury, herring, and salmon. In general, the warm water surface fish arrive from the south, while the colder water fish arrive from the north. Dolphinfish (Coryphaenidae) consist of two subspecies in Japan:Coryphaena hippurus and C. equiselis. They originate in the Pacific, are found widely in tropical and sub-tropical seas, and reach approximately 0.5m to 2m in length. Dolphinfish migrate in groups from May to December and move northward (agari shiira) in waters around Japan during the summer season, moving south (modori shiira) again after late summer.

  • Abel Janszoon Tasman Was the First European Explorer to Reach the Islands of Van Diemen's Land (Now Tasmania) and New Zealand
    ABEL TASMAN AUSTRALIAN HISTORY: ABEL TASMAN Abel Janszoon Tasman was the first European explorer to reach the islands of Van Diemen's Land (now Tasmania) and New Zealand. In 1642 the Governor-General of the Dutch East Indies, Anthony Van Diemen sent Tasman on an expedition to explore and map out New Holland, where a lot of Dutch ships had become shipwrecked due to the Roaring Forties winds. He was ordered to see how far south New Holland reached and sailed south and then east. Although Tasman did not find the continent of Australia, he did come across the island of Tasmania, (landing at Frederick Henry Bay, named after the Chief Magistrate of the Netherlands) on the 24th November 1642. He named the island Van Diemen’s Land in honour of, the Dutch governor general. Tasman claimed the island for Holland by leaving the Dutch flag and a pole with the Dutch East Indies markings on it. Tasman mapped the coast of Van Diemen’s Land before continuing east crossing what is now called the Tasman Sea and discovered both islands of New Zealand before returning to the East Indies. His voyage proved that Australia was not part of a great south continent that stretched all the way to the South Pole. Following his expedition, Australia was referred to as New Holland instead of Terra Australis or Zuid Landt (South Land) to recognise that the Dutch had claimed the land. Upon Tasman’s return from his first voyage of New Holland in 1642, the Governor-General was not pleased, since Tasman did not find gold or any land that was considered wealthy or any trading opportunities.

  • The French and Terra Australis
    The French and Terra Australis MARGARET SANKEY* All those interested in Australian history will be aware of the long European quest for the mythical Terra australis incognita, punctuated by the discovery of coasts of New Holland by the Dutch in the seventeenth century, and not abandoned until the late eighteenth century when Captain James Cook, during his second voyage, finally demonstrated that there was no vast inhabited continent sUlTounding the South Pole. In the English­ speaking world, the history of the Southern Hemisphere has been traditionally dominated by the English achievements. The search for Terra australis is thus seen as culminating in the discovery of the east coast of Australia and the subsequent implantation of colonies along the Australian coastlines. In recent years, the French contIibution to the early exploration and mapping of New Holland is increasingly being recognised. Although most Australians know something of the ill-fated expedition of La Perouse, last heard of when he sailed from Botany Bay in 1788, voyages such as those of D'Entrecasteaux (sent in search of La Perouse in 1791) and Baudin (sent on a scientific voyage to New Holland by Napoleon Bonaparte in 1800) are only now beginning to attract the attention they deserve. The pioneering work done over the last few decades by John Dunmore, Leslie Marchant, Frank Homer, and more recently other scholars such as Edward Duyker, has demonstrated the achievements of the French explorers and revealed the wealth of documentation they accumulated about New Holland during the earliest days of European settlement. * Professor Margaret Sankey, FAHA, holds the McCaughey Chair of French Studies at the University of Sydney.
