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.

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.

B South Esk Catchment
B SOUTH ESK CATCHMENT 1.0 Hydrology The South Esk River rises in the North Eastern highlands near Mathinna initially travelling southwards before passing through the Fingal Valley and finally turning northwards and draining into the Tamar River estuary at Launceston. Upstream of the confluences with the Macquarie and Meander rivers the major tributaries include the Break O’Day, St Pauls and Nile rivers. Many smaller streams contribute water to the South Esk mainly from the North- East highlands around Ben Lomond (eg Storeys Creek and Buffalo Brook). 1.1 Historical Background Measurement of river heights in the South Esk River has a long history. Unfortunately these measurements are not always useful indicators of flow due to changes in the channel such as growth and destruction of vegetation, aggradation and scouring of river beds, etc. Such changes provide unstable relationships between gauge height and flow. Nevertheless, many of the gauge height stations continue to be maintained and in many instances are the major tools used for flood warning. The South Esk is a relatively flat river for much of its length and there are often large areas where natural backwaters occur. There are therefore limited opportunities along the river to collect stream flow information and it was not until the 1950's that two reasonable locations were instrumented. These two sites - one at Llewellyn and the other at Perth - have collected streamflow information for around 40 years and are therefore invaluable in assessing the water yields, flood and drought behaviour of the river system. Unfortunately the early record at Llewellyn (prior to 1973) is subject to a major review by the Hydro-Electric Commission and could not be used for this study. -

June 1946 MEM. NAT. Mus. V1cT., 14, PT. 2, 1946. https://doi.org/10.24199/j.mmv.1946.14.06 THE SUNKLANDS OF PORT PHILLIP BAY AND BASS STRAIT By R. A. Keble, F.G.S., Palaeontologist, National Jiiiseurn of Victoria. Figs. 1-16. (Received for publication 18th l\fay, 1945) The floors of Port Phillip Bay and Bass Strait were formerly portions of a continuous land surface joining Victoria with Tasmania. This land surface was drained by a river system of which the Riv-er Y arra was part, and was intersected by two orogenic ridges, the Bassian and King Island ridges, near its eastern and western margins respectively. \Vith progressive subsidence and eustatic adjustment, these ridges became land bridges and the main route for the migration of the flora and fauna. At present, their former trend is indicated by the chains of islands in Bass Strait and the shallower portions of the Strait. The history of the development of the River Yarra is largely that of the former land surface and the King Island land bridge, and is the main theme for this discussion. The Yarra River was developed, for the most part, during the Pleistocene or Ice Age. In Tasmania, there is direct evidence of the Ice Age in the form of U-shaped valleys, raised beaches, strandlines, and river terraces, but in Victoria the effects of glaciation are less apparent. A correlation of the Victorian with the Tasmanian deposits and land forms, and, incidentally, with the European and American, can only be obtained by ascertaining the conditions of sedimentation and accumulation of such deposits in Victoria, as can be seen at the surface1 or as have been revealed by bores, particularly those on the N epean Peninsula; by observing the succession of river terraces along the Maribyrnong River; and by reconstructing the floor of Port Phillip Bay, King Bay, and Bass Strait, and interpreting the submerged land forms revealed by the bathymetrical contours. -

1 | P a g e What is an Arboretum? Distinct from a forest, park or nursery an arboretum is, in a sense, an outdoor museum of trees. More commonly, a modern arboretum is a botanical garden containing living collections of specimen plantings of trees and shrubs and woody plants and is intended at least in part for scientific study. The Tasmanian Arboretum offers beauty, biodiversity, ecology, botany, recreation and education, and is of historical importance. About this publication A record of the first 16 years of the growth and development of the Tasmanian Arboretum—from its commencement—was covered in the publication, An Introduction and History of Development from 1984 to 2000 by Stephen M. King with help from John Bell. This current publication brings that history up to the present, drawing heavily on Stephen King’s booklet for the early years, and utilising information from Newsletters and AGM Presidents Reports for the years 2000 to 2019. This updated work is the result of the team effort of Judith Hughes, Alan Blakers and Deby Adair. Judith has been associated with the Arboretum from its inception to the present day, providing invaluable elements, details and insights. For the many up to date photos now included we thank and acknowledge Greg Close, Hennie Meyer and Alan Blakers. Revised August 2020. Location The Tasmanian Arboretum is situated on the North West Coast of Tasmania, 12 km South of Devonport and 1 km West of Eugenana village, and is open daily from 9am to sunset. 2 | P a g e Contents What is an Arboretum? 2 About this -
