    [A History of the Aclare Mine – South Australia] – Silver and a Trace of Gold – J.K. Chilman

    A very good copy of Special Publication No 1 celebrating 100 year of the Department of Mines and Energy, South Australia.

    Soft silvered cover, 212 pages with numerous illustrations … from photographs, sketches, maps, mine plans etc.

    From discovery in the 1840 to the end of that century … and the continuing heritage interest an extremely thorough work.

    R.K Johns in his preface … “Silver and a Trace of Gold” establishes the mood of these times and painstakingly and sympathetically traces the events connected with speculation and mining investment, the opening and closure of mining operations, and the developments in metallurgical practice and smelting of mixed metallic ores. It not only traces the history of the Aclare mine, and the Kanmantoo- Callington mining field, but has relevance to the whole mining history in the State” … a bit dry but does capture the breadth and depth of this study.

    A Mining History well presented and more … processes etc

  • Vintage Microscope Slide – Pollen from the Antarctic

    Vintage Microscope Slide – Pollen from the Antarctic

    Nice condition, quality mount of an unusual subject – Pollen from the Coast of the Antarctic.

    Nice deep mount with well preserved coloured mount rings. We are unsure who the preparer was but would suggest they must have been a professional given the mount is in such good shape. The hand written label looks familiar to us but we still cannot pick the preparer.

    The location likely in the area immediately south of South America … as these pollen samples would have started life in warmer climes.
