Newsletter - September 2000

Glenys welcomed everyone to the meeting including new member Lynette. After some lengthy discussions on Shell Show matters we were treated to a slide show presented by Betty with help from the group who have recently returned from Australian shell shows. These were Glenys and Kelvin Stace, Betty, Nancy, Rae, and Glad. They travelled from Brisbane to Townsville to Mt Isaac. Many old friendships were renewed and much hospitality given. There were some revealing slides on early morning scenes after sleeping in rows on the floor! The warm water at Dingo Beach looked inviting. Rae and Nancy were judges at the Yeppon Shell Show. Betty and Bob Grange were noted in the pictures, their enthusiasm for shells undiminished, even when you have to fight to get a look in at a dealer wares!
The most outstanding shell for Nancy at the show was a specimen of the hairy gastropod Alvinconcha heffleri. It lives in abyssal depths associated with hydrothermal vents. The chemoautotrophic bacteria in its enormous gills can oxidise the sulphur to produce energy. (See Poirieria 15(6)). She tried every way to get her hands on it but to no avail! We did however have an amazing slide to view. The Interpretive Centre at Mt Isaac was enjoyed with life-size models of marsupials. The visit to Lawnhill, on the border of the Northern Territory, was a highlight, they hold the record for the longest time spent in a hired canoe! Three gorges were traversed. The abundant wildlife included many species of birds, fresh water crocodiles and turtles.
Highly recommended was the Cairns sky rail trip with birdís eye view of waterfalls and the rich canopy of the rainforest.
The slides were supplemented by print collages of people, birds and other wildlife. Then of course there were some fabulous displays of shells. Gladys Goulstone had a tray, she has caught the collecting bug!
