A pulley block of this size would have many applications on a ship, including lifting loads such as cargo and sails. It was recovered from the wreck of the Halladale in the 1970s by divers Gary Hansen and Peter Ronald, former Director of Flagstaff Hill. The Falls of Halladale was an iron-hulled, four-masted barque built in Glasgow, Scotland. It was used as a bulk carrier of general cargo. When the ship left New York in August 1908 it was bound for Melbourne and Sydney it’s the cargo in its hold consisted of roofing tiles, barbed wire, stoves, oil, benzene and many other manufactured items. On the 15th of November, 1908, after three months at sea and close to its destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland. The captain and 29 crew members survived but most of the cargo was lost, despite two salvage attempts in 1908-09 and 1910. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson's navigational error, not to any technical failure of the ship. The Falls of Halladale was built in1886 by Russell & Co., at Greenock shipyards on the River Clyde, Scotland for Wright, Breakenridge & Co of Glasgow. The vessel was one of several designs of Falls Line of ships named after waterfalls in Scotland. The company had been founded between 1870- 1873 as a partnership between Joseph Russell, Anderson Rodger, and William Todd Lithgow. During the period between 1882-92 Russell & Co. standardised its ship designs, which sped up their building process so much that they were able to build 271 ships during that time. The Falls of Halladale had a sturdy construction built to carry maximum cargo and was able to maintain full sail in heavy gales. It was one of the last of the 'windjammers'. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. Previous to this, heavily loaded vessels could have huge seas break along the full length of the deck, causing serious injury or even death to those on deck. The new, raised catwalk-type decking allowed the crew to move above the deck in stormy conditions.The Falls of Halladale shipwreck is listed on the Victorian Heritage (No. S255). The vessel was one of the last ships to sail the Trade Routes from Europe and the Americas. Also of significance is that the ship was one of the first ships to have fore and aft lifting bridges as a significant safety feature that is still in use on modern vessels today. The block and pulley is an example of ship rigging equipment used on sailing ships during the 19th and early 20th centuries that transported goods around the world. It represents aspects of Victoria’s shipping industry and maritime history.A pulley block; metal frame with three sheaves. The block is in a fragile condition. It is also large and heavy.

This double-sheaved wooden ship’s block or pulley is a mechanical device used for lifting and moving heavy objects. It has two grooved wheels joined together, each with an axle between the cheeks or sides of the grooved wheel. Blocks and tackle are included in a ship’s rigging. These pulleys and ropes are used for the mechanical advantage they provide for lifting, moving and re-arranging the setting of the sails, which are very heavy work. Blocks are also used to load and unload the ship’s cargo. The FALLS of HALLADALE- The sailing ship Falls of Halladale was an iron-hulled, four-masted barque, used as a bulk carrier of general cargo. She left New York in August 1908 bound for Melbourne and Sydney. In her hold was general cargo consisting of roofing tiles, barbed wire, stoves, oil, and benzene as well as many other manufactured items. After three months at sea and close to her destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland on the 15th of November, 1908. The captain and 29 crew members survived, but her cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson's navigational error, not too technical failure of the Clyde-built ship. The Falls of Halladale was built in1886 by Russell & Co., at Greenock shipyards on the River Clyde, Scotland for Wright, Breakenridge & Co of Glasgow. The ship had a sturdy construction built to carry maximum cargo and was able to maintain full sail in heavy gales, one of the last of the 'windjammers' that sailed the Trade Route. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. The new, raised catwalk-type decking allowed the crew to move above the deck in stormy conditions.This artefact is important as it is an example of the materials and design of late-19th century ship’s rigging equipment. The object is also significant for its association with the historic sailing ship Falls of Halladale, wrecked in local waters in the early 20th century. The clipper ship Falls of Halladale shipwreck is of historical significance and is listed on the Victorian Heritage Register, No. S255. She was one of the last ships to sail the Trade Routes. She was one of the first vessels to have fore and aft lifting bridges. The vessel is an example of the remains of an international cargo ship and also represents aspects of Victoria’s shipping industry.Rope block, wooden double-sheave mechanical device with a short length of chain attached and remnants of the metal frame.

WARRNAMBOOL MECHANICS’ INSTITUTE Warrnambool's Mechanics' Institute (or Institution as it was sometimes called) was one of the earliest in Victoria. On 17th October 1853, a meeting was held where it was resolved to request the Lieutenant Governor of the Colony to grant land for the erection of a Mechanics' Institutes building. A committee was formed at the meeting and Richard Osburne chaired the first meeting of this committee. The land on the North West corner of Banyan and Merri Streets was granted but there were no funds to erect the building. The Formal Rights of the Warrnambool Mechanics' Institute's encompassed its aims and these were officially adopted in1859; "This Institution has for its object the diffusion of literary, scientific, and other useful knowledge amongst its members, excluding all controversial subjects, religious or political. These objects are sought to be obtained by means of a circulating library, a reading room, the establishment of classes, debates, and the occasional delivery of lectures on natural and experimental philosophy, mechanics, astronomy, chemistry, natural history, literature, and the useful and ornamental arts, particularly those which have a more immediate reference to the colony." The Warrnambool Mechanics' Institute opened its first reading room in November 1884 in the National School building at the corner of Banyan and Timor Streets. The Institute was funded by member subscription, payable on a quarterly, half-yearly or yearly basis. Samuel Hannaford, the Manager of the Warrnambool Bank of Australasia, was the first Honorary Secretary of the Mechanics' Institutes, and an early President and Vice-President. He also gave several of the early lectures in the Reading Room. Another early Secretary, Librarian and lecturer was Marmaduke Fisher, the teacher at the National School. Lecture topics included The Poets and Poetry of Ireland', 'The Birth and Development of the Earth', 'The Vertebrae - with Remarks on the pleasures resulting from the study of Natural History' and 'Architecture'. In 1856 the Reading Room was moved to James Hider's shop in Timor Street, and by 1864 it was located in the bookshop of Davies and Read. In the 1860's the Mechanics' Institute struggled as membership waned but in 1866, after a series of fundraising efforts, the committee was able to purchase land in Liebig Street, on a site then called Market Square, between the weighbridge and the fire station. A Mechanics' Institute building was opened at this site in August 1871. The following year four more rooms were added to the main Reading Room and in 1873 the Artisan School of Design was incorporated into the Institute. The same year Joseph Archibald established a Museum; however, it deteriorated when he was transferred to Bendigo in 1877. In 1880, with Archibald's return to Warrnambool, the Museum was re-established, and in 1885 a new building was built at the back of the Institute to accommodate the re-created School of Design, the Art Gallery and the Museum. In 1887 the Museum section was moved to the former courthouse in Timor Street (for some time the walls of the building formed part of the TAFE cafeteria but all is now demolished)). In 1911 the Museum was transferred back to the original building and the management of the Mechanics' Institute was handed over to the Warrnambool City Council. The Museum and Art Gallery became one and housed many fine works of art, and the Library continued to grow. The building was well patronised, with records showing that at the beginning of the 20th century there were between 500 and 800 visitors. During World War One the monthly figures were in the thousands, with 3,400 people visiting in January 1915. The Museum was a much - loved Institution in Warrnambool until the contents of the Museum and Art Gallery were removed to make room for the Warrnambool City Council Engineers' Department. The contents were stored but many of the items were scattered or lost. When the original building was demolished the site became occupied by the Civic Centre, which included the new City Library. (The library was temporarily located in the old Palais building in Koroit Street.) In the process of reorganisation the Collection was distributed amongst the community groups: -The new City Library took some of the historical books and some important documents, historic photographs and newspapers. -The Art Gallery kept the 19th Century art collection and some of the artefacts from the museum. -The Historical Society has some items -The State Museum has some items -Some items were destroyed -Flagstaff Hill Maritime Village has old newspapers, Government Gazettes, most of the Mechanics' Institute Library, ledgers and documents connected to the Mechanics' Institute Library, some framed and unframed artworks and some photographs. The Warrnambool Mechanics' Institute Library book collection is deemed to be of great importance because it is one of the few collections in an almost intact state, and many of the books are now very rare and of great value. WARRNAMBOOL PUBLIC LIBRARY The Warrnambool Mechanics’ Institute (WMI) was formed by a voluntary community group in 1863, within six years of Warrnambool’s beginnings, and its Reading Room opened in 1854. The WMI operated until 1963, at which time it was one of the oldest Mechanics’ Institutes in Victoria. Mechanics’ Institutes offered important services to the public including libraries, reading rooms and places to display and store collections of all sorts such as curiosities and local historical relics. In 1886 a Museum and Fine Arts Gallery were added to the WMI and by the beginning of the 20th century, there was also a billiards room and a School of Art. By this time all Mechanics’ Institutes in country Victoria had museums attached. Over the years the Warrnambool Mechanics’ Institute Library was also known as the Warrnambool Public Library the Warrnambool Library and the Free Library. Early funding from the government was for the “Free Library”. The inscription in a book “Science of Man” was for the “Warrnambool Public Library”, donated by Joseph Archibald in 1899. Another inscription in the book “Catalogue of Plants Under Cultivation in the Melbourne Botanic Gardens 1 & 2, 1883” was presented to the “Warrnambool Library” and signed by the author W.R. Guilfoyle. In 1903 the Warrnambool Public Library decided to add a Juvenile Department to library and stock it with hundreds of books suitable for youth. In 1905 the Public Library committee decided to update the collection of books and added 100 new novels plus arrangements for the latest novels to be included as soon as they were available in Victoria. In July 1911 the Warrnambool Council took over the management of the Public Library, Art Gallery, Museum and Mechanics’ Institute and planned to double the size of the then-current building. In 1953, when Mr R. Pattison was Public Librarian, the Warrnambool Public Library’s senior section 10,000 of the 13,000 books were fiction. The children’s section offered an additional 3,400 books. The library had the equivalent of one book per head of population and served around 33 per cent of the reading population. The collection of books was made up of around 60 per cent reference and 40 per cent fiction. The library was lending 400 books per day. In 1963 the Warrnambool City Council allocated the site of the Mechanics’ Institute building, which included the Public Library, Museum and Art Gallery, for the new Municipal Offices and the Collections were dispersed until 1971. The Warrnambool Library took over the Mechanics’ Institute Library’s holdings on behalf of the Warrnambool City Council. Since the closure of the Warrnambool Mechanics’ Institute the exact location and composition of the original WMI books and items have become unclear. Other materials have been added to the collection, including items from Terang MI, Warrnambool Court House and Customs House. Many of the books have been identified as the Pattison Collection, named after the Librarian who catalogued and numbered the books during his time as Warrnambool Public Librarian in the time before the Mechanics’ Institute closed. It seems that when Warrnambool became part of the Corangamite Regional Library some of the books and materials went to its head office in Colac and then back to Warrnambool where they were stored at the Art Gallery for quite some time. Some then went to the Warrnambool Historical Society, some stayed at the Art Gallery and some were moved to Flagstaff Hill Maritime Village. The various stamps and labels on the books held at Flagstaff Hill show the variety of the collection’s distribution and origin. The books in the collection at Flagstaff Hill Maritime Village date from the 1850s to the late 1950s and include rare and valuable volumes. Many of the books are part of the “Pattison Collection” after the Warrnambool’s Public Librarian, Mr R. Pattison.

Taken on 25 October 1930, various houses with the Hume Dam under construction are depicted in the background. The construction of the Hume Dam took place from 1919 to 1936. At the time of construction, it was the second largest dam in the world. It was also one of the earliest civil projects developed after the Federation. Some of the Dam workers consisted of World War I veterans. Dam workers often settled their families in Mitta Junction Village and Wodonga. Archaeological surveys were completed by Austral Archaeology, which was done when the Department of Land & Water Conservation was doing work to improve Hume Dam. The archaeological report that came out of the survey recommended three sites of interest where archaeological excavation should be done: Camp Ganger’s Quarters, Stableman’s Quarters, and the Industrial Dump. The excavation uncovered artefacts. Mitta Mitta: Mitta Mitta is situated between Mount Welcome and Mount Misery. It is named after the river that explorers Hume and Hovell discovered in 1824. The town would eventually become a huge gold mining town. Mitta Mitta is called Midamodunga by the local Indigenous peoples Wodonga: Wodonga is situated on the Murray River and is part of North East Victoria.
