Photograph - Black and White, Ballarat, c1854
The town you see had over 50,000 people. Bridge Street on the left is well established. The crude pans and cradles of the early “diggers’ were already giving way to steam power and the deep shafts of the “miners”. Money and machinery were needed to get to the deeper leads, and the smoke stacks of the great company mines can be seen across the photo.Four black and white photographs placed together to make a panorama of Ballarat looking towards Mt Warrenheip. On the left the chimney and gasometer indicate the corner of Dana Street and Albert Street. This is now the Ballarat Law Courts. The photograph is behind glass in a black frame. These four photographs were taken from the slope of the Ballarat School of Mines where the Uniting Church now stands. When joined they give a panoramic view of one of the world’s richest alluvial goldfields. The Waterloo Mine was one of the first deep shafts and was sunk at the foot of the Dana Street hill. Its tailings are seen in the second photo from left. The following was typed and placed with the framed image. Ballarat Circa 1858 This is the most significant of the photographs of early Ballarat. The photographer stood on the slope near S.M.B. where the Wesley Church now stands and took four pictures. When joined them have this panoramic view of one of the world's richest alluvial goldfields. Seven years earlier this landscape was empty. The town you see had over 50,000 people. Bridge Street on the left is well established the Ballarat gas Company stands on the same place as today.

Cocks Pioneer Mine El Dorado, Power Station No. 2 was established in 1914 and located near junction of Reid's and Clear Creeks, Byawatha. Cocks Pioneer Electric Gold & Tin Mine Company was formed in 1899. The company's first power station, located at the eastern end of the valley began operating with its 340 Kilowatt steam-powered generator. By 1909, from 2,500,000 cubic yards worked, reported recovery was 17,284 ounces of gold and 224 tons of tin ore. By 1909, Cocks Pioneer’s power plant had become inadequate and uneconomical. The barge was floated downstream about a mile, but lost time caused the operations to cease. Following testing, a new mine was established by diverting Reid's Creek at a cost of £25,000. Settling dams were built, one of which held 1,935,900 cubic feet. Sold earth banks, built against a wall of stringy bark saplings constructed and laced with vertical props, were built. In 1914, the company was reformed as Cock’s Pioneer Gold and Tin Mines NL, another power station was constructed at the western end of the township, near the junction of Clear and Reid's Creeks. From 6,800,000 cubic yards of material processed, the returns were 64,397 ounces of gold and 855 ton of tin. Cocks Pioneer mine then moved the barge downs stream and continued sluicing. In 1929 Cocks Pioneer Electric Gold and Tin Mining Company ceased operations due to a drop in values. Cock’s Pioneer Gold and Tin Mines NL carried on large-scale hydraulic sluicing operations until 1941.

National Wool Museum
Textile - Community Textile Tapestry, Lisa Kendal et al, WARM, 2016
WARM was a community textile art project that saw over 250 knitters come together to create a beautiful collage tapestry. Made entirely from wool, the artwork contains more than 1000 individual hand knitted sections. The project takes aim at global warming, it highlights both the causes and solutions for us to create a sustainable and safe climate for future generations. Lisa Kendal, the co-creator of the project, said “One of the problems in the world is that we have forgotten how to warm ourselves with wool. We have become too dependent on fossil fuels (for heating)”. This is the key idea surrounding the project. WARM began as two large scale images created by Lars Stenberg. The first image is a landscape scarred by coal mining. The second image is the same landscape only many decades later. Regeneration and regrowth have taken over the landscape and hidden the past coal mine completely. In its place is a beautiful landscape including trees, native flowers, a lake, lots of greenery and wind turbines. From March to the end of August in 2016, knitters worked hard to create the over one thousand pieces that came together to form the final tapestry. The pieces were all designed by Fibre Artist Georgie Nicolson of Tikki Knitting Designs, who converted the second image of the healed landscape into patterns for the 250 plus knitters to follow. These patterns included unusual designs such as gum leaves, trees, native flowers and even the wind turbines. During several days of installation, the knitted pieces were stitched together by Lars Stenberg over a picture of the first image of the operational coal mine. They worked to create the second image of the renewed landscape; like an enormous collage. The WARM project was donated to the National Wool Museum in 2021. It was a much-loved hanging within the Ballarat Hospital for many years before coming to the museum. More information about the project can be found on the following website. http://www.seam.org.au/warm The tapestry is made from 1000+ hand knitted sections stitched together to make an image. In the foreground of this image is a large gum tree that stretches from the bottom left to the top right corner. The trunk of this tree follows the left edge of the tapestry, with foliage from the gum tree spanning its top border. The bottom third of the tapestry is predominantly green grass with yellow, pink and red flowers providing sporadic colour. The middle third encompasses a lake, with orange colours surrounding the banks of the water as opposed to the green grasses of the bottom third. To the right of the lake are wind turbines. The top third of the tapestry is blue sky with white clouds. It also contains the previously described gum tree leaves. Each piece of the tapestry is 100% wool and was hand knitted and stitched together. The Tapestry is accompanied by an oil painting on canvas. It is a painting that matches the tapestry and served as a template for the final tapestry. Finally, the tapestry is accompanied by another pointing on wood board. This final panting is of a coal mine. This is the setting before regeneration and regrowth have reclaimed this site, which is the theme captured in the final tapestry. In the foreground of the coal mine painting is the same gum tree described in the tapestry; however, it is grey and sickle with only 4 leaves visible at the top border, compared to the numerous leaves in the tapestry. Also in the foreground is a broken barb wire fence adding to the unwelcoming nature of the site. The colour scheme of this image is of dark greys and browns. A coal fired power plant can be seen in the final third of the image with four chimneys emitting plumes of smoke into the sky. In front of this power plant is the spiral shape of a coal mine, burrowing deep into the earth’s crust. Inside of the coal mine 3 yellow trucks are seen mining and transporting coal to the top of the mine.warm, community textile tapestry, knitting, community artwork, global warming -

'Messrs. George Phillips and Richard Williams erected a water wheel crushing machine near the site of the Old Albert shaft at Diamond Hill'. ( Bendigo Advertiser 4th June, 1890). The lack of water available for the venture from the water race caused much controversy in the following years. There was only enough water available in July 1890, to allow the company to operate three head of a ten head stamper. The site of the water wheel is still visible on the side of the water race at Diamond Hill. Mr. Geo Phillips held 1000 shares in the float of the Kangaroo Hydraulic Crushing & Gold Mining Company. He was one of the largest shareholders. (Victorian Government Gazette 72 Page 2260, 1893) Black and white photocopy. Image shows the Phillip's Water Wheel on Diamond Hill, Bendigo.
