Worldwide, more than 100 million lambs are castrated, and their tails are docked each year. Numnuts is a technological innovation to improve animal welfare. It combines traditions with innovation. In the mid-1990s it was scientifically shown that the immense pain felt during castration and tail docking could be significantly reduced with the use of anaesthetic. For the next 15 years, the industry said the cost the welfare devices and development were too high. But todays ethical consumer has demanded that sheep have no more pain. Initiated in Glasgow in 2009, Numnuts took nearly a decade to develop. Here you can see five stages of development, from an early prototype to the Numnuts device farmers use today. Each phase of development took years of on-farm trails to achieve the final product. Today there is even NumOcaine, an approved local anaesthetic used by Numnuts. Using the simple elastrator ring and adding an anaesthetic injector, Numnuts delivers pain relief during tail docking and castration. In the world’s first rubber ring applicator with a pain relief delivery mechanism. Through innovation and consumer pressure the wool industry is going through a moment of rapid change.

The world’s most ecologically distinct bird lives in the native grasslands of Victoria - but only just. The plains-wanderer is a small bird that was once widespread across the grasslands of south-eastern Australia. Today there are fewer than 1000 mature birds in the wild. The plains-wanderer is under threat due to habitat loss caused by overgrazing, cropping and suburban sprawl. Unlike most other birds, female wanderers are larger and more colourful and the males take care of the chicks. They are only about 15cm tall and weigh between 40-80g for the male and 55-90g for the female. Their intricate plumage mirrors the colours of their grassland home so they blend in perfectly with their surroundings. The plains-wanderer’s origins date back to when Australia was part of the Gondwana supercontinent over 60 million years ago. They are so biologically distinct that their extinction would result in the loss of a branch of the tree of life. A fussy grass dweller, they like neither too much nor too little grass. That is where sheep grazing can help. After years of low numbers in Victoria, plains-wanderer populations have been increasing in Terrick Terrick National Park in north west Victoria, as sheep grazing maintains the grass in the park at a suitable level. With the right management, this ecologically important bird species is continuing to survive in the native grasslands of Victoria. Managing these habitats for the plains-wanderer can also support the conservation of many other threatened plant and animal species. Object: Nest of plains-wanderers by Mary-Jane Walker, 2020.

Selection of metal files used for cutting wool bale stencils with an accompanying box. Not all files belong to this box as some are too long to fit within. Used in Denny’s Lascelles Bow Truss building by Maurice Dalton who was the foreman of the building for 34 years. Files are ‘Cup Brand’ – ‘Best refined steel files’ and were manufactured by the no longer trading Moss & Gamble Brothers LTD at the Franklin works in Sheffield, England.

12 steel files of varying length, thickness and shape. The longest and thickets are in a flat half circle with some files being fully flat, others complete cylinders, one is a complete square and others are in the shape of a triangle. Cardboard box is brown with black inscription on lid of box.

Two short sections of flooring cut for distribution during Deakin Universities ‘Open Day’ in December 1994. This was during the conversion of Dalgety Wool Store to Deakin University’s Woolstore Campus. These small pieces of timber are part of Geelong’s history and were salvaged from the Dalgety Woolstores during the renovations. Hundred of meters of ironbark, red gum, pine and other timbers, some more than a century old, were reclaimed from the site and have been recycled as furniture and featured building materials for the woolstore campus. The old brick stores, located on a formerly neglected section of the Corio Bay shoreline, now house the administration and chancellery, architecture and building schools, information technology services, the student union, a cafeteria and, as the focal facility, a Great Hall seating 1500 people and acoustically tuned for symphony orchestras. The refit was developed from the existing grid of substantial timber columns and beams extending over 52,000 square metres. This framework was filled with lightweight panels to enclose workplaces and removed in some parts to establish courtyards, atriums and streets. The brick facades were redefined with new doors and double-glazed windows in proportion to original fenestration. Bright colours and industrial finishes identify the new insertions.

Square sections of redgum lumber cut into floorboards. The sides of the lumber have a grove cut on one side and a matching section to fit within this groove on the other side. This has been done to ensure the floorboards have a tight and consistent fit with one another. The bottom of the lumber also has an additional grove running through the middle of the redgum. On top, one of the sections of lumber has three nail holes, which travel all the way through to the bottom of the wood.

In the early nineteenth century larger Australian wool producers sent all their wool by sailing ship to London, where colonial auctions were held in November, January, February and March. Wool bales were carried from the farm on drays or wagons pulled by bullocks, horses or camels to port warehouses. In these times, wool transport could take anything from a week to six months. Ships, such as the Lightning, were then loaded and raced each other to get to London ahead of their rivals. The wooden ship 'Lightning' was destroyed by fire while loading wool at Geelong 31 Oct. 1869. Scuttled in Corio Bay and the remains later blown up. Reputed to be one of the fastest sailing ships. Famous in the Australian passenger trade.

The Edina was one of the longest serving steam vessels anywhere in the world. Built on the Clyde by Barclay, Curle & Co. she was an iron hull single screw steamer of 322 tons with three masts. In 1855 Edina was requisitioned by the Admiralty from her owners the Leith, Hull & Hamburg Steam Packet Co. to carry stores and horses to the Black Sea during the Crimean War. After return to her owners Edina traded around the UK and Mediterranean before being purchased and used as a blockade runner during the American Civil War carrying cotton from the Confederate states in 1861. Edina arrived in Melbourne under sail in March 1863 and was purchased by Stephen Henty for use from ports in western Victoria and later carried gold prospectors across the Tasman to New Zealand. After a refit in 1870 she was used in the coastal trade along the Queensland coast for Howard Smith until returning to Victoria and the Melbourne-Geelong trade as a cargo-passenger vessel. The Edina had two narrow escapes from destruction in 1898 and 1899 when she collided with other steamers, both being sunk. A further refit in 1917 altered her appearance with a new mast, funnel, bridge and promenade deck. By 1924 Edina had made over 12,000 Melbourne-Geelong passages and carried over one million people on the service. A further collision in July 1931 which sank the tug Hovell forced Edina onto a mudbank on Port Phillip Bay. She was taken out of service in 1938 but was later renamed Dinah and used as a lighter until 1958 when she was broken up and her remains used as land-fill.

There are several different designs of drench guns within the NWM Collection that show the change in their development over time. On the left side of this gun white paint indicates the adjustable dose lever. It is a sliding scale from 10 to 0 cubic centimetres of liquid (now typical measure in millilitres). It also has a small and straight tip suggesting this gun was typically used for dosing Lambs as opposed to ewes. The manual adjuster helped to minimise cases of overdosing which can be fatal for livestock while the additional curvature helped to ensure the liquid reached the desired location within the sheep’s mouth. This desired location is on the left rear of the sheep’s tongue (from the sheep’s point of view) as this is where the oesophagus is located. The main risks are that drench may be delivered into the lungs via the trachea or “windpipe”, which can also prove fatal. The opening to the trachea which leads to the lungs is in the middle of the back of the throat. Another risk is the throat can also be damaged due to rough handling.

Silver metal with black finishing drench gun. Straight tip on gun protrudes from the body which feature a thin squeezable trigger to the front of the body. The main bulk, which the trigger is squeezed towards has silver cylinder on top of the handle where tubing carrying the liquid drench into the gun attaches. The small section of tubing still attached has a yellow/orange appearance from remanence of drench which would have been this colour.
