  • Around the Bend
    Cultural Studies Review volume 18 number 1 March 2012 http://epress.lib.uts.edu.au/journals/index.php/csrj/index pp. 86–106 Emily Bullock 2012 Around the Bend The Curious Power of the Hills around Queenstown, Tasmania EMILY BULLOCK UNIVERSITY OF TASMANIA Approaching the town of Queenstown you can’t help but be taken aback by the sight of the barren hillsides, hauntingly bare yet strangely beautiful. This lunar landscape has a majestic, captivating quality. In December 1994 after 101 years of continuous mining—A major achievement for a mining company—the Mount Lyell Mining and Railway Company called it a day and closed the operation thus putting Queenstown under threat of becoming a ghost town. Now, with the mine under the ownership of Copper Mines of Tasmania, the town and the mine are once again thriving. Although Queenstown is primarily a mining town, it is also a very popular tourist destination offering visitors unique experiences. So, head for the hills and discover Queenstown—a unique piece of ‘Space’ on earth.1 In his discussion of the labour of the negative in Defacement: Public Secrecy and the Labour of the Negative, Michael Taussig opens out into a critique of criticism. ISSN 1837-8692 Criticism, says Taussig, is in some way a defacement, a tearing away at an object that ends up working its magic on the critic and forging a ‘curious complicity’ between object and critic.2 Taussig opens up a critical space in which to think with the object of analysis, cutting through transcendental critique, as a critical defacement, which, in the very act of cutting, produces negative energy: a ‘contagious, proliferating, voided force’ in which the small perversities of ‘laughter, bottom-spanking, eroticism, violence, and dismemberment exist simultaneously in violent silence’.3 This complicity in thinking might be charged by critical methodologies which engage in, and think through, peripatetic movements.

Googk A CATALOGUE OF THE MINERALS KNOWN TO OCCUR IN TASMANIA, WITH NOTES ON THEIR DISTRIBUTION• .Bv W. F. PETTERD. THE following Catalogue of the Minerals known to occur and reeortled from this Island is mainly prepared from specimen~ contained in my own collection, and in the majority of instances I have verified the identifications by careful qualitative analysis. It cannot claim any originality of research, 01' even accluac)" of detail, but as the material has been so rapidly accumulating during the past few )'ears I bave thoug-ht it well to place on record the result of my personal observation and collecting, wbich, with information ~Ieaned from authentic sources, may, I trust, at least pave tbe way for a more elaborate compilation by a more capable authority. I have purposely curtailed my remarks on the various species 80 Rs to make them as concise as possible, and to redulle the bulk of the matter. As an amateur I think I may fairly claim tbe indulgence of the professional or otber critics, for I feel sure tbat my task has been very inadequately performed in pro­ portion to the importance of the subjeot-one not only fraugbt with a deep scientific interest on account of tbe multitude of questions arisin~ from the occurrence and deposition of the minerals them­ selves, but also from the great economic results of our growing mining indu.try. My object has been more to give some inform­ ation on tbis subject to the general student of nature,-to point out tbe larg-e and varied field of observation open to him,- than to instruct the more advanced mineralo~ist.

Twblvetrees, F.G.S., and W. F. Petterd, C.M.Z.S. The following Notes lay no claim to be an exhaustive description of our familiar '• diabase" or "dolerite" rock, which plays such an important part in the geology and physical configuration of our Island. The present object is rather to place upon record some inferences drawn from the examination of numerous microscopical sections of speci- mens collected or received from all parts of Tasmania. It is by accumulating the results of observations that stepping stones are formed to more complete knowledge. A glance at Mr. R. M. Johnston's geological map of Tasmania, issued by the Lands Office, will show the share this rock takes in the structure of the Island. It occupies the whole upland area of the Central Tiers. On the northern face of the Tiers—the Western Tiers as they are here called—there is a tongue of the rock prolonged northwards past IMount Claude. At their north-west corner it forms or caps mountains, such as Cradle Mountain (the highest in Tas- mania), Barn Bluff, Mount Pelion West. Eldon Blufi: forms a narrow western extension. Mount Sedgwick is a western out-lier ; Mount Dundas another. In that part of the island it is also found at Mount Heemskirk Falls, and on the Magnet Range, two miles north of the Magnet Mine. Mounts Gell and Hugel are also western out-liers.
