Book - Papers and Addresses, Thomas Brassey, author, Papers and Addresses Mercantile Marine and Navigation from 1871 to 1894, 1894
The papers in this work are focused on Thomas Brassey (1836-1918) who was born and educated in England. They include the period 1871-1894, before he accepted the position of Governor of Victori, Australia, in 1895. During that time, he'd won a seat in parliament, which he held for 18 years, and for periods was a civil lord and parliamentary secretary for the Admiralty. He was passionate about the sea and addressed his naval and maritime concerns in public lectures, letters, pamphlets and books. He was also for a time lord-in-waiting to Queen Victoria and president of the Institute of Naval Architects. This book is from Flagstaff Hill's ‘Pattison Collection’, a collection of books and records that was originally owned by the Warrnambool Mechanics’ Institute, which was founded in Warrnambool in 1853. It was edited by Captain S. Eardley-Wilmot, and published by Longmans, Green and Co. of London. The Longmans, Green and Co. was originally founded in 1724 in London by Thomas Longman under the name Longman. In August of that year, he bought the two shops and goods of William Taylor and set up his publishing house there at 39 Paternoster Row. The shops were called Black Swan and Ship, and it is said that the 'ship' sign was the inspiration for Longman's Logo. After many changes of name and management, the firm was incorporated in 1926 as Longmans, Green & Co. Pty Ltd. The firm was acquired by Pearson in 1968 and was known as Pearson Longman or Pearson PLC. Interestingly, the logo in some books, such as “Steam Turbines 2nd edition, published in 1922” has the year “1724” but the logo in books such as “Advanced Agriculture, published in 1894” has the year “1726” in the logo.The book is significant for publishing historical papers and addresses by Lord Thomas Brassey, former Governor of Victoria before Australia’s Federation. Brassey was passionate about naval and maritime matters in public and government capacities. The work is important for its connection with the publisher Longmans, Green and Co., of London, a firm that has been established for over two centuries, renowned for publishing encyclopedias, dictionaries, books on English grammar, textbooks, poetry, reference books, novels, magazines and more. The book has additional importance for its connection to the Pattison Collection, which, along with other items at Flagstaff Hill Maritime Village, was originally part of the Warrnambool Mechanics' Institutes’ Collection. The Warrnambool Mechanics’ Institute book collection has historical and social significance for its strong association with the Mechanics Institute movement and its important role in people's intellectual, cultural and social development throughout the latter part of the nineteenth century and the early twentieth century. The collection of books is a rare example of an early lending library and its significance is enhanced by the survival of an original collection of many volumes. The Warrnambool Mechanics' Institute’s publication collection is of both local and state significance.Papers and Addresses Mercantile Marine and Navigation from 1871 to 1894 Author: Lord Brassey Arranged and Edited Captain S.

Ticket, The Warrnambool Steam Navigation Co Ltd, 1873
This card relates to an excursion aboard “The SS Otway leaving the Warrnambool Jetty at 8 am April 18th 1873 to go to Belfast and Portland courtesy of the Warrnambool Steam Navigation Company Limited which was originally called the Warrnambool Steam Packet Company. The Otway was the second steamer purchased by the company. It had a number of ships which traded along the coast including, the Nelson, Julia Percy, Otway and The Edina. The Edina was originally owned by Stephen Henty who was operating it from Portland but he sold it to the new company for £8500. Henty then withdrew from the Belfast and Warrnambool trade for a time but it proved to be a competitive business. The name was changed again in 1878 to The Western Steam Navigation Company and the SS Otway was put up for sale. This card relates to one of the first trips, if not the first trip, taken by the SS Otway Shipping was a major part of the history of Warrnambool and this ticket is a link to one of the earliest passenger and freight services which operated along the coast.Small cream card with light purple text with company name at the top. Capital letters done in scroll lettering. There are feint markings in the centre of the back which appear to have been rubbed off.Signed by Captn Selby.

Book, Royal Australian Air Force, Standard Notebook for Initial Training Schools: Air Navigation, August 1942
This notebook contains information on air navigation and electrical science. It was issued to Roy Eliason (449852), a Shepparton local who enlisted in 1944 and served as a Leading Aircraftman with the 2nd Operational Training Unit Mildura. Contents include: Appendix I: Law, Discipline, Administration and Organisation, Hygiene and Sanitation, Notes on Meteorology, Definitions, The principles of flight, Airframes, Engine; Appendix II: Mathematics problems for revision.This notebook has significant research potential, as it bears the service number of the owner: Roy Eliason. Roy Eliason's service history is well documented in the National Archives of Australia and this book provides an insight into a period of his service. Notebooks such as this were presumably issued to new recruits in the early stages of their service. Though this copy is in fair condition with several signs of wear, these signs may in fact increase the significance of the item, demonstrating the frequent use of this item in the hands of a new recruit to the Royal Australian Air Force. Series of pages bound via twine passed through four holes along left side. Front and back cover are card with orange vinyl/fabric strip and paper cover bearing title text.

Book, A Complete Epitome of Practical Navigation - J W Norie, 1848
This book is a 19th Century treatise on aids to navigation. It belonged to John Cowtan who held land near the Cassady's Bridge area in Caramut Road today (he was related to the Cassady family) and who is mainly important in the history of Port Fairy. Captain John Cowtan was a ship's master for John Griffiths and a Launceston entrepreneur and ship owner between 1839 and 1844. In 1847 he went into partnership with John Bland, establishing a merchant's business with riverside buildings at the Port Fairy wharf. He left Port Fairy in the 1860s. The date of John Cowtan's signature in this book is 1849 (certainly a very early one in our history) and inside the front cover he has written notes about the local weather, mainly as it affected sailing conditions in late 1849 and early 1850. These notes are of great historical interestThis book is of great interest because it belonged to a Port Fairy historical figure and because of the hand written weather notes inside the front cover. This is a hard covered,leather bound book of 680 pages. It contains printed text, illustrations, tables, maps and sketches.One page is torn Some pages are stained. .

Document - Navigation Chart, Portsmouth to Canary Islands, Ca. 1928
This is an Official British Admiralty Navigation Chart, one of a set of 65 charts donated together with a wooden chart case. It was published and printed in London in 1928 by the British Admiralty. Navigation charts are drawn by professional hydrographers and describe the geography of land and water, enabling a water based navigator on board vessels such as ships to safely negotiate between ports locally and around the world. They are drawn to a particular standard with common symbols noting landmarks. The charts are used in conjunction with other navigational instruments and tools to calculate the vessel’s exact location and a safe route to its destination.The set of charts and their chart are of significance as examples of equipment and documents used to navigate the oceans of the world, particularly to Australia.

Functional object - Fresnel Glass Lens, Early 20th century
A Fresnel lens is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use primarily in lighthouses. Made from high-quality glass Fresnel lenses were used originally in lighthouses and later for many other applications They were later being used for automobile headlamps, brake, parking, and turn signal lenses, and many other applications. Fresnel lenses used in lighthouses were considered state of the art from the late 19th through to the middle of the 20th century. The subject item is a Fresnel replacement lens used in a ships navigation light. For lighthouses, these lenses have now been replaced with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. The lens design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The catadioptric form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source making the light visible from greater distances.The subject item at this time cannot be associated with a historical event, person or place, provenance is unknown, the item is a replacement for a ships navigation light and it is believed to have been produced before 1950.Fresnel glass replacement lens for a navigation lamp of a ship.
