Mission to Seafarers Victoria
Article, A Woman's Melbourne Letter
A detailed description of the Mission and its activities written by a woman: Western Mail (Perth, WA : 1885 - 1954), Friday 13 December 1918, page 34 A WOMAN'S MELBOURNE LETTER. Melbourne, Dec. 4. There is an idea abroad, which as regards Melbourne, at any rate, is quite erroneous, that our sailors are not as well looked after as our soldiers, and that the noble men of the Mercantile Marine are much neglected ! For once, perhaps, my readers will pardon a letter dealing with only one subject, but the steady, unostentatious work done by the Ladies' Harbour Light Guild, in connection with the mission to seamen in Melbourne could not be adequately explained if dismissed in the usual short paragraph. Some of the most prominent names in Melbourne are associated with this guild and with the Mission Chaplain, and Mrs. Gurney Goldsmith, the members have made the Seamen's Institute a real home for those sailors of the Mercantile Marine, who touch our port. What we as a community owe to those men by their heroism in recent hostilities is certainly more understood by this band of enthusiastic workers than by the community generally. By using their unflagging energies, and influence on the sailor's behalf they endeavour to discharge a debt to which in some way or other we could and should all contribute. Even the most casual person can, if he thinks at all, sum up a few of the things our sailors - other than those belonging to our glorious navy - have done for us. On the spur of the moment we remember that those of the Mercantile Marine, are the men who manned our transports, who carried our wheat and wool, to oversea markets; who kept us in touch with our loved ones abroad; who kept the fires going in the furnaces of the great leviathans, bringing our wounded soldiers home again; who never flinched when self-sacrifice was demanded; who cared, with that tenderness, innate in all sailors, for the women and children, when the passenger ships were struck a dastardly blow by the wicked enemy; who, mocking death, gave up life with a heroism all the more heroic because it was always taken as a matter of course! Is it any wonder, then, that the members of the Ladies' Harbour Light Guild make it their business to provide a bright, homelike, spot in Melbourne, where the sailors are always certain of a cherry welcome ashore? The members of the guild are admirably drafted! The 360 non-workers each pay £1 1s. per annum. The workers, of whom there are between 700 and 800, donate 2s. 6d. and school members - it is confidently hoped that gradually all the schools will take an active interest in the mission - 1s. a year. The knights of the guild - as the men members are designated - are responsible for any sum they wish to name, from 5s. a year upwards. Everything is paid for out of these revenues, with the exception of a small grant from the Home Mission Fund - and such is the organisation, and management, that the entire concern is quite free from debt. The Seamen's Church and Institute, where the "Harbour Lights" gleam so brightly, is situated right in the midst of all the bustle and turmoil of the wharves, at the end of Flinders-street. The building, comprising chapel, and institute under the one red tiled roof, is grey stuccoed, with a small tower, from which flaunts the flag of 'The Flying Angel" - the badge of the guild. A visit to the institute makes one fully appreciate the boon the place must be to the voyage worn, weary, sailor. The atmosphere is eminently social in its best sense. While the architecture imparts an elegance, and quiet dignity which soothes by the very subtlety of its charm. With its comfortable furniture, its wealth of flowers, and the happy, wholesome, feminine influence which prevails everywhere, the quality which stands for the magic word "home" abounds. The Chaplain in the course of conversation said: -"We try to make this really a free club for sailors." But the habitues would probably tell you it was far more than that to them. The Institute is excellently appointed, and every little corner seems to have its particular history. It was built after the model of one of the old mission churches in California, and retains something of the old world attraction, while yet it combines all the advantages of modern, practical, conveniences. On entering the door the first thing, one notices is a huge compass, inlaid upon the floor, evidently to indicate one's proper bearings for it points due north - to the chapel! Only one other seamen's mission in the world boasts such a compass. As the sailor swings through the entrance he finds the office on his right, and there is, here, always a smiling face to welcome the shy, or timid, new comer. Quite a real post office is staffed by members of the guild, and all the letters received are listed alphabetically. Therefore, the expectant sailor has just to run his eye down the list, and he can immediately see whether there is a letter for him or not. If he is fortunate, he comes up to the member in charge, who unlocks the box, and produces the longed for missive. The boys are always encouraged to answer letters - and to write them. Often a few words about their mother, and their own home, will provoke a sleeping memory into activity. The writing room is well stocked with paper, envelopes, pens, and ink. The tables are so divided to ensure the utmost privacy, and through a calculated chain of circumstances, many an anxious mother receives a letter from her sailor lad, who, perhaps, might not have written but for these kindly inducements. The central hall - where social evenings are held every other night besides two special concerts a week - is inviting in the extreme. A handsome piano affords opportunity for those musically inclined. The tables are strewn with papers. The walls are bright with pictures, and here, and there, is a carved model, of a ship. One, of especial interest, is a model of "The Roon" carved, and presented by a French sailor. This German vessel will always be remembered in Australia. For it was across her bows that the first hostile shot was ever fired in Australian waters. In the corner is the canteen. It was fitted up entirely from the proceeds of a quotation calendar compiled by one of the members. The sailors may at any time, get a teapot of tea, or a tray of eatables, at a nominal cost. Before the canteen was in existence they had to go out for refreshments! - and sometimes they did not come back! Groups of sailors sit chatting at the tables. Half a dozen Swedes laugh and talk among themselves, for the simple reason they know no other language than their own. Several British sailors cluster about a dark-eyed Welsh lad - a perfect Celtic type - who, although only about twenty years of age, has been the victim of the Hun five times. Mines and torpedoes sank the ships he was in, either in the Channel or off the English coast, four times; and it is to his fifth experience, when the Inverness was wrecked, that everyone is eagerly listening. "We were in the boats eight days," he was saying, "I was pretty well mangled when they picked me up. The sufferings we endured were awful. At last we managed to reach Rapa, a Hawaiian island. The natives thought we were Germans, and came at us with spears. When they found we were British, they were awfully good to us. They even cried when we left, and the day before the rescue boat arrived they begged us to go into the hills and hide." At another table a Canadian lad - once a sailor - then a soldier, who trained at the Broadmeadows camp - was telling his experiences : - "The voyage which will always stick in my memory," he said, "was to a place which must be nameless. We left the United States not knowing whether we were bound, or what we were going to do. After some weeks we sighted a group of wonderfully beautiful islands, and we headed for the most remote and most lovely of them all. Then, and only then, we learned our mission from the skipper. We were taking their year's supply to a leprosy station! Oh no! I don't blame the skipper for not telling us ! Someone has to do these things, you know. A naval guard saw they didn't come near - and we all got sixty dollars extra. When the job was over we were quarantined on another island for two months, and one little chap - the baby of the crew, not eighteen - developed leprosy, and died before we left. Yes! I'll never forget that voyage, mates! Sometimes, I seem to see Leper's Island yet, with its lavish tropical vegetation and the gorgeous sunsets which stained all the water with blood. Then, too" - here the voice deepened - "there was an English girl - a leper - there. We heard she used to be an actress, and she contracted the disease somehow or other. She was always alone, and always watching us. In the distance we could see her come to the water's edge, and from there she would watch. Just watch . .. . watch . . .watch. ..." "Here come a couple of North Sea chaps," broke in an elderly man after pause. "One of them wounded, too, poor lad." It is not strange that all the sailors flock to the Institute. It is so comfortable, and essentially inviting, besides being full of human interest. The men's quarters comprise reading, writing and dressing rooms - hot and cold baths are always available - billiard room, and a special baggage room, where any sailor may leave his kit for as long as he likes. The payment of 3d. covers its complete insurance. Upstairs are the officers' quarters. These also have their own billiard room, writing and reading rooms, bath and dressing rooms. Just close are the apprentices' quarters - "The Half Deck," as popular parlance has it! The lads also have a billiard room of their own, and indulge in an easy armchair - amongst others - which was a donation from the Milverton School branch of the Guild. It is hoped by the committee to some day utilise the huge empty rooms, which run the length of the whole building. Their ultimate intention is to fit them up as cubicles, or "cabins," as they are to be called. They trust these "cabins" will be donated, either in memory, or in honour, of someone dear to the donor. Another forward movement soon to be put in hand, now that materials are available, is the establishment of "Norla Gymnasium." In a sailors' club such facility for exercise is absolutely essential. The men both need, and miss, exertion. As one boy, who had been backsliding, once said pathetically : -"If only there was something to do to get me into a good sweat, I would be all right." Soon such an one will be helped to swing from the trapese of the Norla Gymnasium into the right track! Sunday is always a fete day at the Institute, for 40 or 50 sailors generally come into tea. The up-to-date kitchen, which is fitted with every labour-saving appliance - all paid for out of working members' half crowns - is then a hive of animation, and methodical order. A formidable row of teapots await filling. Mrs. Goldsmith -, the chaplain's wife - rightly thinks it is far more homely to pour out the tea from a pot, than to serve it straight from the urns. So tea is poured out by a member, who sits at the head of a table gay with flowers, and chats to the guests. These latter are of all nationalities. But the French, the Spanish, Scandinavian, Norwegian - or any other sailor is equally welcome with the British. Two enthusiasts belonging to the Guild actually learnt Norwegian, so that men of this nation would have someone to talk to, and so be less lonely when they reached this, to them, foreign port ! The members of the Guild have their own private suite where they arrange the flow-err and do other necessary odds and ends undisturbed. No one appreciates flowers like a sailor, and the earliest and most beautiful may always be seen adorning the tables and rooms. Teas are served and lectures are held in the "Celia Little Hall," one of the most beautiful portions of the institute. It was erected by the chaplain in memory of his aunt from whom the hall takes its name. The Gothic windows open upon the cloisters, where, in the hot weather, the sailors enjoy their meals out of doors. The cloisters, indeed, form an exquisite spot. They are between a series of sweeping arches which lead to the chapel, and are sheltered by the open balcony of the chaplain's quarters. Grace of contour marks the architecture on every turn. Just around the corner is the chaplain's garden - a patch of green and colour, transformed from a desert waste, by a well-known woman horticulturist. The book room is a department especially valued by the sailors. There are two secretaries, one for home and the other for foreign literature. Books in French, English, Spanish, Scandinavian, Norwegian, and German may be found on the shelves. Each week about 36 convenient parcels of reading stuff are made up. These contain illustrated papers, books in various languages, and magazines. These parcels are eagerly accepted by the sailor with a long monotonous voyage before him. But complete as is every corner of the institute, no part is so well equipped as the memorial chapel erected by the Ladies' Harbour Light Guild, in memory of the officers and men, who have lost their lives during the war. St Peter's - for it is called after the sailor's patron saint - with its hallowed gentle dignity is a veritable sanctuary of peace, perhaps all the more so because it sprang out of war. The fittings are entirely of Australian wood. The pews, given in memory of some loved one by one of the members, are of Tasmanian hardwood. The reredos and altar chairs of carved blackwood. The rich carpet was provided by the members' magical half-crowns. Already this chapel holds memorials of peculiar historical interest. The altar lectern was given in memory of Commander Elwell, who, it will be remembered, was killed at Rabaul, in the early part of the war. The font commemorates two heroes - Nigel Hockley and Fred Hyde, who lost their lives at the hands of the Germans, although they survived the actual torpedoing of their ships, the Galgorn Castle off the coast of Ireland. The mother of one of them wrote out that her son had died as an Englishman should - fighting for the right. This noble sentiment is suitably paraphrased upon the inscription engraved upon the font. Practically every-hing enshrined in the chapel has its own sentimental value. The alms salver of beaten copper, studded with agate, is fragrant with the memory of a saintly woman.The eye of the sailor is caught and held by the pulpit, which is fashioned like a ship's hull and only a twist of rope guides the chaplain up the steps. For the last 13 years the Rev. A. Gurney Goldsmith, M.A., has acted as chaplain to the Seamen's Mission in Melbourne. Before that he and his wife worked in China. Mr Goldsmith visits all the boats and gets in touch personally with the sailor, over whom he has great influence. He is not only their chaplain and friend, but, amongst a wide range of other things, their banker besides. An exchange system exists between the various Missions, and the sailor who has "banked" his money with the chaplain, upon going away, receives a cheque which is cashed - minus exchange - by the chaplain of the next port. Mr. Goldsmith will tell you he has a soft spot in his heart for on old sailor he calls "Paddy." This ancient mariner has been wrecked ten times. It was a long time before the chaplain prevailed upon "Paddy" to partake of the spiritual and secular advantages afforded by the institute. He would not come, he said, until he could do so "with a good heart." Finally he frankly admitted that he had no "friends like those of 'the Flying Angel,' " and that he eventually proved his own "good heart" will be shown in this story. One day he came in to the chaplain and said bluffly, "Well, sir, I've been payin' off some old scores up Carlton way, an' I tells yer, plain, sir, not one of 'em would have seen a penny of their money but for the Mission." The Ladies' Harbour Light Guild has over thirty working suburban branches, and the excellent results achieved at the Institute now will no doubt be considerably augmented in the future. The practical actions of the members do more than anything else to convey the subtle meaning of the name of the Guild. To the visiting sailors the word "ladies" signifies the bread givers; "harbour" safety ; "lights" welcome; "guild" the welding of fraternity, and they one and all tell you the ideals thus embodied are unselfishly carried out by all the ladies who have banded together to care for the sailors' welfare.The article describes the Mission and the use of several spaces a year after its opening and gives details about the daily activities.Digital copy of an article published in the Western Mail on the 13th of December 1918. 717 flinders street, seamen's mission, norla dome, lhlg, reverend alfred gurney goldsmith, celia little room, garden, frederica godfrey -

Hasselblad aerial camera
Aerial photos were used to make maps of forest types, timber resources, to survey logging areas and regeneration, to mark boundaries of public land and new plantations, to identify new roads and tracks, as well as for fire suppression. Infrared film was sometimes used to monitor insect and disease attack. The images needed to sharp, with high contrast, and in a large format (most were printed in B&W on 9-inch by 9-inch glossy photographic paper) with at least a 60% overlap to enable stereoscopic viewing and with a 20-30% side lap to allow for aircraft drift. Preferably, the photo scale was close to the final map scale avoid to problems when enlarging and to reduce distortion. Something was needed to supplement the very expensive and infrequent large-area photography programs. From the mid-1960s Victorian foresters began experimenting with small format 70mm and 35mm cameras which proved simple, practical, cheap and flexible. It was found that any SLR camera could be used provided it had a good quality lens and fast shutter speed (preferably down to 1/1000 second). Motorised cameras with a large film capacity had obvious advantages and were essential when access to the camera was not possible during flight. It is also essential for the shutter to operate at low temperatures and those lubricated with silicones were recommended. Components of a typical FCV Divisional Office system included – A Hasselblad or Vinten 70 mm format aerial camera with a focal plane shutter which could be electrically operated. Interchangeable lenses to allow for different photo scales and flying heights. Several large film magazines, which were loaded in a darkroom, each with a capacity of 100 feet or approximately 500 frames. A remote control for the camera in single-shot mode or automatic firing at selected intervals of 2 to 50 seconds. It also needed a frame counter. A light aircraft was modified with an internal mounting for the camera to keep it level and steady. Often a hole was cut through the floor for the lens. The aircraft also needed an inbuilt 12 Volt DC battery to operate the motorised camera shutter. The front passenger seat was generally removed to improve access to the camera. An Aldis drift sight was also fitted. This might be likened to an inverted periscope and is used to determine drift, to facilitate accurate navigation along flight lines and to determine the exposure interval for stereoscopic overlap. This item is kept at Traralgon.Hasselblad 500 ELM camera with 70mm lens, film pack, motor drive and battery In 1964 Hasselblad started production of a motorized camera, the 500 EL The EL/M is a modified version of the EL, "M" means modified, "EL" electric. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when man first landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. forests commission victoria (fcv), forest measurement, surveying, mapping -

Machine - ES56 Nymph Sailplane
ES 56 Nymph Following the successful introduction of the ES 52 Kookaburra two-seater in mid-1954, Edmund Schneider Ltd designed a higher performance single seat sailplane of similar construction and with similar handling qualities. It was designated the ES 56 and became known as the ES56 “Nymph”. The ES56 Nymph was a success in that it delivered the anticipated performance and was found to have satisfactory flying characteristics. However, only the prototype (“Nymph -I”) and three production examples (“Nymph-II”) were built. Schneiders made some changes to the design before building the production version. The wing chord at the tip on the prototype measured 650 mm. This was reduced to 500 mm for subsequent builds. The explanation is that provision was made in the original design for the possible lengthening of the tapered wing to 13 metres. However, apparently it was decided to retain the 11.900 metre span which allowed the tip chord to be reduced slightly. Other changes included the installation of scissor type air brakes in the wing instead of simple hinged flap spoilers and the addition of a landing wheel behind the skid on the fuselage. On one of the Nymph-II a dorsal was added on top of the fuselage forward of the vertical fin when repairs were made rectifying damage incurred as a result of an accident at Benalla on 31 March 1963. Even before these ES56 gliders were finished, Edmund Schneider Ltd decided to offer a less expensive single seat design to cater in particular for newly solo pilots, the ES57 Kingfisher. With the Kingfisher, Schneiders reverted to a traditional airfoil (Gott 549) for the wing instead of the laminar flow section that was chosen for the Nymph in the pursuit of performance. As such, the Kingfisher was more appropriately characterised as a single seat version of the Kookaburra in comparison to the Nymph. Schneiders continued for a time to offer the ES56 Nymph as a high-performance sailplane. However, its place in the market was soon overtaken by imported designs with superior performance, such as the Schleicher KA6, which Schneiders also imported and built under license. Nymph-I was test flown in December 1955 and entered by Harry Schneider into the gliding championships held at Waikerie from 5th to 16th of that month. Harry finished 12th in the individual placing out of a field of approximately 24. The capabilities of the Nymph were further demonstrated by Harry Schneider in January 1956 with a Gold C flight of 193 miles from Gawler in South Australia to Walpeup in Victoria. Nymph-I was acquired by the Port Pirie Gliding Club in South Australia. It has been saved and restored and is a regular feature at vintage glider rallies in Victoria and New South Wales. See Museum Newsletter No 35 Winter Edition 2017 pages 3 -6, for that story. The Nymph-II production models were delivered by Edmund Schneider Ltd in October 1956 to the Gliding Club of Victoria, the Victorian Motorless Flight Group and the Royal Australian Navy Gliding Association. The VMFG flew its Nymph in the First National Gliding Championships at Tocumwal, NSW, in December 1956 and all three were flown at the Second National Gliding Championships at Benalla in 29th December 1958 to 8th January 1959, delivering competitive performances based on handicap.

The Museum’s exhibit is the ES56, serial number 22, registered as VH-GFE. The glider was flown by the VMFG in Victoria until approximately September 1968. GFA records show that it was transferred to Queensland in 1968, and it passed through several owners until the mid-1970s. Information received indicates that it was flown by the Leichardt Soaring Club at Mount Isa in the (late?) 1960s. The history from then is not presently known except to say that it has been kept in dry storage for many years. It is not known when the glider was last flown. What is Significant? The Schneider ES 56 Nymph single seat sailplane, serial number 22, designed and built in 1955-1956, by Edmund Schneider Ltd in Adelaide. It was delivered to its original owner, the Victorian Motorless Flight Group, in October 1956, and registered as VH-GFE on 5 March 1957. How it is Significant? The ES56 Nymph is of historical, aesthetic, scientific and research, and social significance to the Australian gliding community. Why it is Significant? The ES56 is of historical significance as it was designed and built by Edmund and Harry Schneider. The Schneiders immigrated to Australia after the end of the second world war bringing with them considerable expertise in relation to glider design and construction. Over the following decades they maintained a close association with the Gliding Federation of Australia and the gliding clubs and through their glider production made a major contribution to the sport. The ES56 is part of that story. The ES56 in its design and construction exhibits the glider construction technology of the time, which principally consisted of lightweight wooden framework skinned with ply and doped fabric. It exbibits design innovation, notably the use of a laminar flow wing profile in pursuit of better glide performance. Also, considerable attention was given to simplifying the structure in order to keeping cost and the weight low. The ES56 played a useful role at gliding clubs where it was operated, especially the late 1950s and early 1960s and is remembered well by pilots who flew her. The glider is in the course of restoration and provides an insight into the skills and workmanship that were involved in design, building and maintenance of these wooden aircraft. It is of aesthetic and scientific and research significance.
