This skylight frame would have been fitted on the Newfield’s poop deck (or raised deck that forms the roof of a cabin at the aft or rear of the ship). It would have covered and protected a glass pane that allowed light to enter the area below desk. The glass pane from the skylight is missing. The Newfield was a three-masted iron and steel barque, built in Dundee, Scotland, in 1869 by Alexander Stephen and Sons. It was owned by the Newfield Ship Company in 1890 and later that year It was registered in Liverpool to owners Brownells and Co. The Newfield left Sharpness, Scotland, on 28th May 1892 with a crew of 25 under the command of Captain George Scott and on 1st June left Liverpool. She was bound for Brisbane, Australia, with a cargo of 1850 tons of fine rock salt. On the night of 28 August 1892, the Captain mistook the Cape Otway light for that of Cape Wickham (King Island) and altered tack to the north and east putting the vessel on a collision course with the Victorian coast. At around 3:40 am the Newfield struck rocks about 100 yards from shore, and 5 feet of water filled the holds immediately. The captain gave orders to lower the boats which caused a disorganised scramble for safety among the crew. The starboard lifeboat was cleared for lowering with two seamen and two apprentices in her, but almost as soon as she touched the water she was smashed to bits against the side of the vessel, and only one of the four reached safety ashore, able seaman McLeod. The rough sea made the job of launching lifeboats very difficult. The first two lifeboats launched by the crew were smashed against the side of the ship and some men were crushed or swept away. The third lifeboat brought eight men to shore. It capsized when the crew tried to return it to the ship for further rescue The rescue was a difficult operation. The Port Campbell Rocket Crew arrived and fired four rocket lines, none of which connected with the ship. Peter Carmody, a local man, volunteered to swim about one mile offshore to the ship with a line to guide the fourth and final lifeboat safely to shore. He was assisted by James McKenzie and Gerard Irvine. Seventeen men survived the shipwreck but the captain and eight of his crew perished. The Newfield remained upright on the reef with sails set for a considerable time as the wind slowly ripped the canvas to shreds and the sea battered the hull to pieces. The Marine Board inquiry found the wreck was caused by a "one-man style of navigation" and that the Captain had not heeded the advice of his crew. For his heroic efforts, Peter Carmody was awarded the Bramley-Moore medal by the Liverpool Shipwreck and Humane Society for Saving Life at sea on January 21st 1893. The medal and a letter of congratulations were donated to Flagstaff Hill Maritime Museum by Peter Carmody's granddaughter Norma Bracken and her son Stuart Bracken on 25th May 2006. Flagstaff Hill’s collection of artefacts from the Newfield is significant for its association with the shipwreck Newfield, which is listed on the Victorian Heritage Registry. The collection is additionally significant because of the medal awarded to a local man Peter Carmody. The Newfield collection historically also represents aspects of Victoria's shipping history and its association with the shipwreck.Skylight, frame only. The heavily encrusted brass framework has eight bolts around the long side, and four metal bars forming two ‘v’ shapes across the centre. The frame is, slightly concave towards the inner side.

The artefact is a short cross-section of part of a functional part of a brass fitting that suspended a gas lamp, providing structural support, and internally, supplying the gas for its ignition. It combines elegant design with the elements required for safe and efficient delivery of gas. It was recovered from the LOCH ARD shipwreck site. There are similar artefacts in the Flagstaff Hill collection. The LOCH ARD left Gravesend (London) on 2 March 1878, bound for Melbourne, with a crew of 37, 17 passengers, and a diverse and valuable cargo of manufactured goods, luxury items, and refined metal. Some of the cargo was intended for Melbourne’s first International Exhibition to be held in 1880. At 3 am, 1 June 1878, the ship was wrecked against the high limestone cliffs of Mutton Bird Island on Victoria’s south west coast near Port Campbell. Only two people survived the disaster — Tom Pearce, a male crew member, and Eva Carmichael, a female passenger. The cargo proved too difficult to salvage in the vessel’s exposed condition and was largely written off. The manifest of goods in the LOCH ARD’s holds included “Fittings gas (4 cases)”. The gas lighting of streets, public buildings, and the dwellings of wealthier private citizens, was already well advanced in the cities and major towns of the Australian colonies. In 1841 Sydney was the first to be gas lit with 23 street lamps, 106 hotel lamps, and 200 private residences connected to the Darlinghurst “gasometer” by an underground network of metal pipes. “The dim days of oil and tallow are gone by!” pronounced one newspaper, flushed with civic pride. The 1850s Gold Rush promoted a similar attitude of confidence and affluence in the Colony of Victoria. In 1855 Melbourne was connected to its own system of subterranean gas pipes despite the same high rates of 25 shillings per 1000 cubic feet being charged, (reduced to 15 shillings in 1865 with cheaper sources of coal). By1858 Kyneton had its own gasworks to light the town (fuelled by eucalyptus leaves) and Geelong followed suit in 1860. Had the LOCH ARD reached its intended destination in 1878, it is probable that the 4 cases of brass gas light fittings on board would have found a ready market.The gas fitting is significant for its association with the LOCH ARD shipwreck, which is of State significance and is listed on the Victorian Heritage Register S417. The fitting is an example of a late 19th-century plumbing and light fitting.A pressed brass gas light fitting, recovered from the wreck of the LOCH ARD. The elegant and functional fitting extends from an ornate 8cm diameter ceiling flange, and comprises two short lengths of fluted column pipe with a brass joiner that are severed (cut off) at the end. Within this decorative outer layer of 3cm diameter is a full length brass tube liner, which is in turn protecting a narrow 0.75cm copper gas pipe that also runs full length.

History of the Loch Ard: The Loch Ard got it’s name from ”Loch Ard” a loch which lies to the west of Aberfoyle, and to the east of Loch Lomond. It means "high lake" in Scottish Gaelic.The vessel belonged to the famous Loch Line which sailed many vessels from England to Australia. The Loch Ard was built in Glasgow by Barclay, Curdle and Co. in 1873, the vessel was a three-masted square-rigged iron sailing ship that measured 79.87 meters in length, 11.58 m in width, and 7 m in depth with a gross tonnage of 1693 tons with a mainmast that measured a massive 45.7 m in height. Loch Ard made three trips to Australia and one trip to Calcutta before its fateful voyage. Loch Ard left England on March 2, 1878, under the command of 29-year-old Captain Gibbs, who was newly married. The ship was bound for Melbourne with a crew of 37, plus 17 passengers. The general cargo reflected the affluence of Melbourne at the time. Onboard were straw hats, umbrella, perfumes, clay pipes, pianos, clocks, confectionery, linen and candles, as well as a heavier load of railway irons, cement, lead and copper. There were other items included that were intended for display in the Melbourne International Exhibition of 1880. The voyage to Port Phillip was long but uneventful. Then at 3 am on June 1, 1878, Captain Gibbs was expecting to see land. But the Loch Ard was running into a fog which greatly reduced visibility. Captain Gibbs was becoming anxious as there was no sign of land or the Cape Otway lighthouse. At 4 am the fog lifted and a lookout aloft announced that he could see breakers. The sheer cliffs of Victoria's west coast came into view, and Captain Gibbs realised that the ship was much closer to them than expected. He ordered as much sail to be set as time would permit and then attempted to steer the vessel out to sea. On coming head-on into the wind, the ship lost momentum, the sails fell limp and Loch Ard's bow swung back towards land. Gibbs then ordered the anchors to be released in an attempt to hold its position. The anchors sank some 50 fathoms - but did not hold. By this time the ship was among the breakers and the tall cliffs of Mutton Bird Island rose behind. Just half a mile from the coast, the ship's bow was suddenly pulled around by the anchor. The captain tried to tack out to sea, but the ship struck a reef at the base of Mutton Bird Island, near Port Campbell. Waves subsequently broke over the ship and the top deck became loosened from the hull. The masts and rigging came crashing down knocking passengers and crew overboard. When a lifeboat was finally launched, it crashed into the side of Loch Ard and capsized. Tom Pearce, who had launched the boat, managed to cling to its overturned hull and shelter beneath it. He drifted out to sea and then on the flood tide came into what is now known as Loch Ard Gorge. He swam to shore, bruised and dazed, and found a cave in which to shelter. Some of the crew stayed below deck to shelter from the falling rigging but drowned when the ship slipped off the reef into deeper water. Eva Carmichael a passenger had raced onto the deck to find out what was happening only to be confronted by towering cliffs looming above the stricken ship. In all the chaos, Captain Gibbs grabbed Eva and said, "If you are saved Eva, let my dear wife know that I died like a sailor". That was the last Eva Carmichael saw of the captain. She was swept off the ship by a huge wave. Eva saw Tom Pearce on a small rocky beach and yelled to attract his attention. He dived in and swam to the exhausted woman and dragged her to shore. He took her to the cave and broke the open case of brandy which had washed up on the beach. He opened a bottle to revive the unconscious woman. A few hours later Tom scaled a cliff in search of help. He followed hoof prints and came by chance upon two men from nearby Glenample Station three and a half miles away. In a complete state of exhaustion, he told the men of the tragedy. Tom then returned to the gorge while the two men rode back to the station to get help. By the time they reached Loch Ard Gorge, it was cold and dark. The two shipwreck survivors were taken to Glenample Station to recover. Eva stayed at the station for six weeks before returning to Ireland by steamship. In Melbourne, Tom Pearce received a hero's welcome. He was presented with the first gold medal of the Royal Humane Society of Victoria and a £1000 cheque from the Victorian Government. Concerts were performed to honour the young man's bravery and to raise money for those who lost family in the disaster. Of the 54 crew members and passengers on board, only two survived: the apprentice, Tom Pearce and the young woman passenger, Eva Carmichael, who lost her family in the tragedy. Ten days after the Loch Ard tragedy, salvage rights to the wreck were sold at auction for £2,120. Cargo valued at £3,000 was salvaged and placed on the beach, but most washed back into the sea when another storm developed. The wreck of Loch Ard still lies at the base of Mutton Bird Island. Much of the cargo has now been salvaged and some items were washed up into Loch Ard Gorge. Cargo and artefacts have also been illegally salvaged over many years before protective legislation was introduced in March 1982. One of the most unlikely pieces of cargo to have survived the shipwreck was a Minton majolica peacock- one of only nine in the world. The peacock was destined for the Melbourne 1880 International Exhibition in. It had been well packed, which gave it adequate protection during the violent storm. Today the Minton peacock can be seen at the Flagstaff Hill Maritime Museum in Warrnambool. From Australia's most dramatic shipwreck it has now become Australia's most valuable shipwreck artifact and is one of very few 'objects' on the Victorian State Heritage Register.The shipwreck of the Loch Ard is of significance for Victoria and is registered on the Victorian Heritage Register ( S 417). Flagstaff Hill has a varied collection of artefacts from Loch Ard and its collection is significant for being one of the largest accumulation of artefacts from this notable Victorian shipwreck. The collections object is to also give us a snapshot into history so we are able to interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's social and historical themes of the time. The collections historically significance is that it is associated unfortunately with the worst and best-known shipwreck in Victoria's history.
