An octant is an astronomical instrument used in measuring the angles of heavenly bodies such as the sun, moon and stars at sea in relation to the horizon. This measurement could then be used to calculate the altitude of the body measured, and then the latitude at sea could also be calculated. The angle of the arms of an octant is 45 degrees, or 1/8 of a circle, which gives the instrument its name. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in Philadelphia. While both have a legitimate and equal claim to the invention, Hadley generally gets the greater share of the credit. This reflects the central role that London and the Royal Society played in the history of scientific instruments in the eighteenth and nineteenth century's. There were also two others who are attributed to having created octanes during this period, Caleb Smith, an English insurance broker with a strong interest in astronomy (in 1734), and Jean-Paul Fouchy, a mathematics professor and astronomer in France (in 1732) In 1767 the first edition of the Nautical Almanac tabulated lunar distances, enabling navigators to find the current time from the angle between the sun and the moon. This angle is sometimes larger than 90°, and thus not possible to measure with an octant. For that reason, Admiral John Campbell, who conducted shipboard experiments with the lunar distance method, suggested a larger instrument and the sextant was developed. From that time onward, the sextant was the instrument that experienced significant development and improvements and was the instrument of choice for naval navigators. The octant continued to be produced well into the 19th century, though it was generally a less accurate and less expensive instrument. The lower price of the octant, including versions without a telescope, made it a practical instrument for ships in the merchant and fishing fleets. One common practice among navigators up to the late nineteenth century was to use both a sextant and an octant. The sextant was used with great care and only for lunar sightings while the octant was used for routine meridional altitude measurements of the sun every day. This protected the very accurate and pricier sextant while using the more affordable octant for general use where it performs well. The invention of the octant was a significant step in providing accuracy of a sailors latitude position at sea and his vessels distance from land when taking sightings of land-based landmarks.Octant with metal handle, three different colored shades are attached, in wooden wedge-shaped box lined with green felt.

Used as an agricultural hand tool for mowing grass or harvesting crops. It is historically used to cut down or reap edible grains, before the process of threshing. Replaced by horse drawn and then tractor machinery. Used by the early farmers in the Kiewa Valley.The steel blade is curved with a pointy end. It is attached to a long, slim wooden shaft with a slight S curve. It has 2 handles, one about half way along the shaft and another near the top both at right angles to the shaft. This results in the handles being on slightly different planes and makes it comfortable for the user when working. scythe, hand tool, mowing, harvesting

REF: SHNN article Oct/Nov 1991: Pharmacy was purchased from Mr Nye by C L Mitton in 1933; later moved to 139 Union Road. Research: Stanley Morris Nye (born Ballarat in 1889, son of a Methodist minister; served AIF in WW1) moved to Surrey Hills from Auburn after 1922. He was the first occupant of 131 Union Road which was built in 1924. He is listed in the 1924,1927 and 1931 electoral rolls at 86 Canterbury Road, Surrey Hills. He died aged 44 years in December 1933 and Charles Leslie Mitton took over the business. Charles Leslie Mitton was practising in Newmarket prior to taking over the pharmacy in 1933, the year he also married Ethel Sylvia Stevenson. They lived at 65 Union Road until c1940 when they moved to Kenmare Street, Box Hill North. The pharmacy passed to his son John and daughter Rosalind Lorraine (1937-1997)Black & white photo of a man in a white coat, identified as Charles Leslie Mitton, standing outside his pharmacy in Union Road, Surrey Hills.

This is one of a series of photos donated by Arthur Lyons. From 1907 a cab service operated from near the railway gates in Union Road. It was established and maintained by Mr C Fraser until c1916. George Rea either took over then or set up in opposition; he retired in 1945. Fred Lyons initially worked for George until he set up his own business. In time he changed over to a motor vehicle and continued his service until 1960. Frederick Adolphus Lyons (1891-1980) was born in Surrey Hills, son of Thomas and Catherine Lyons. He married Elizabeth Ruby Hall in 1918. They lived just around the corner at 55 Sunbury Crescent. The Lyons’ home in Sunbury Crescent was called ‘Knopshambury’ - this was probably a misspelling of Knockshanbally in Co Kilkenny, the birth place of Fred’s father, Thomas Edmund Josias Lyons (1846-1915). Arthur Lyons was born in Surrey Hills on 12 Jun 1920. He became a motor mechanic / welder and lived at 55 Sunbury Crescent. The donation was made while he was in hospital. He died shortly afterwards (23 Sep 1990). Donation was finalised by a neighbour, Mrs Florence Ann Armitstead, wife of Glen Victor Armitstead. Glen was a local hairdresser. They moved to 11 Sunbury Crescent after their marriage in 1939. Arthur had no relatives to distribute the material to.Black and white photo of Fred Lyons dressed in suit and cap standing on the footpath beside his taxi.

This 97km Bairnsdale to Orbost extension through rugged terrain was reputed to have been the most difficult rail project undertaken in Victoria. This wooden bridge was one of the unique railway bridges of the East Gippsland Railway line. Mundic Creek Bridge is of unique design because the line crosses at a very sharp angle. This bridge like many others on the line have "disappeared". This one, probably because of a bushfire.The Bairnsdale to Orbost rail line contains the most varied range Of timber & timber composite bridges on any Victorian line.

True North is at the centre of the north pole This is a fixed point at the top of the planet. The majority of our navigational charts are orientated so that they use true north as their reference point. This is because true north doesn’t move. Magnets don’t point towards true north however. They point toward magnetic north which is in a different geographical place.

The artist: Marianne Louise Charlotte Amalie Wehl (19 Sept. 1867, Mt Gambier; 26 Oct. 1926, Melbourne), a flower painter who was active in South Australia and Victoria, and not to be confused with Marie Magdalene Wehl. Connection with Baron von Mueller: Von Mueller’s younger sister, Clara married Doctor Eduard Wehl and they lived in South Australia. They had 14 children, 6 of whom collected and painted botanical studies – some now in the National Herbarium, Melbourne. A cousin of Doctor Wehl – Carl Wehl – married Sophia Caroline (née Gorte) and one of their daughters was Marianne Wehl. It is recorded that von Mueller visited the Wehls and D’Altons in Halls Gap (Henrietta D'Alton was also a painter of wildflowers), so it is hard to believe that there is no influence at least. Von Mueller had over 1,400 collectors/artists working for him and 225 of them were women and children. Their work is housed in the National Herbarium, Melbourne. The donor believes that Marianne contributed to this work. There is no record of that, however, as only 169 of the artists have been identified, it may be a possibility. Marianne was one of six children of Carl Jakob Wilhelm Wehl (1830–1899) and Sophia Caroline Wehl (née Gorte) (1843–1920). She never married. https://data.environment.sa.gov.au/Content/Publications/JABG34P001_Dowe.pdf The plants: All of the plants painted by Marianne Wehl's in this donation were identified by Botanist Neil Marriott & Wendy Marriott, in July 2022. Neil Marriott said that the quality and beauty of these botanical studies made it easy for them to identify all the plants. He suggested they may be some of the first paintings of Grampians wildflowers. This makes the paintings highly important scientifically and botanically. Visitors to WAMA will be able to compare them with today’s plants in the Endemic Garden. Neil marvelled that Marianne found the specimens, as some of them are endemic and found only in the highest parts of the Grampians (Mt Rosea, Mt William and Major Mitchell Plateau) and are listed as rare and endangered. Some of these same rare plants have now been propagated by the WAMA team and in winter 2022 were planted in WAMA's Endemic Garden. Left to right: (Neil's comments) Tetratheca ciliata - Black-eyed Susan. Common and widespread. Marianthus bignoniaceus –Orange Bell-Climber. Confined to drainage lines and winter-wet areas, generally well shaded. A most beautiful light climber with the Grampians being its only location in Victoria, but amazingly, it is also found in small numbers in the wetter parts of the Mt Lofty Ranges and on Kangaroo Island in South Australia. Although not strictly endemic, it has been propagated for planting in our endemic garden due to its rarity in Victoria. Leptospermum myrsinoides - Heath Tea-tree. Common and widespread.

It has been restored by lightstation staff in 2002. The phone has a fixed mouth piece and is attached to the lantern room wall on a timber box mount. Dating from the early twentieth century, it is the earliest of four telephones at the lightstation and the sole box-mounted model, and is also the only telephone in the lighthouse. It has a crank handle, a separate black hand piece and an inclined horizontal shelf for jotting down notes. The four telephones provided an intercom system that facilitated communication between the lightstation buildings. Four other wall-mounted phones remain at the Cape Nelson Lightstation but unlike the Gabo Island example they do not provide a rest for jotting down notes. As a fixture, the telephone is part of the building fabric and is included in the existing Victorian Heritage Register extent of registration for the Gabo Island Lightstation (H1773).
