In February 1913 the Ballarat Junior Technical School opened its doors to its 86 pupils. The old bluestone building in the grounds of the Dana Street Primary School became their temporary for eight years. In its early years the school offered only a two-year course. The first year was of a general nature giving a thorough grounding in Mathematics and Instrumental Drawing, and introducing students to the various branches of trade work. The second-year students studied for the Junior Technical Certificate and specialized in a course of their choice - either a trade (Woodwork or Fitting and Turning) or a course leading to higher studies at the School of Mines. The photograph shows the students outside the school building. Musical instruments, trophy and shield are shown. When World War 1 began, the school formed a 16 piece Bugle Band. A squad of Junior Cadets led by Mr A Williams and later Mr H Wakeling competed at the South Street contests.

This tin of pastels contains the pastels most likely used by Dr Angus in creating his pastel drawing in 1932, which is on display in the in Flagstaff Hill's Port Medical Office. The tin of pastels was donated to Flagstaff Hill Maritime Village by the family of Doctor William Roy Angus, Surgeon and Oculist. It is part of the “W.R. Angus Collection” that includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. ABOUT THE “W.R.ANGUS COLLECTION” Doctor William Roy Angus M.B., B.S., Adel., 1923, F.R.C.S. Edin.,1928 (also known as Dr Roy Angus) was born in Murrumbeena, Victoria in 1901 and lived until 1970. He qualified as a doctor in 1923 at University of Adelaide, was Resident Medical Officer at the Royal Adelaide Hospital in 1924 and for a period was house surgeon to Sir (then Mr.) Henry Simpson Newland. Dr Angus was briefly an Assistant to Dr Riddell of Kapunda, then commenced private practice at Curramulka, Yorke Peninsula, SA, where he was physician, surgeon and chemist. In 1926, he was appointed as new Medical Assistant to Dr Thomas Francis Ryan (T.F. Ryan, or Tom), in Nhill, Victoria, where his experiences included radiology and pharmacy. In 1927 he was Acting House Surgeon in Dr Tom Ryan’s absence. Dr Angus had become engaged to Gladys Forsyth and they decided he further his studies overseas in the UK in 1927. He studied at London University College Hospital and at Edinburgh Royal Infirmary and in 1928, was awarded FRCS (Fellow from the Royal College of Surgeons), Edinburgh. He worked his passage back to Australia as a Ship’s Surgeon on the on the Australian Commonwealth Line’s T.S.S. Largs Bay. Dr Angus married Gladys in 1929, in Ballarat. (They went on to have one son (Graham 1932, born in SA) and two daughters (Helen (died 12/07/1996) and Berenice (Berry), both born at Mira, Nhill ) According to Berry, her mother Gladys made a lot of their clothes. She was very talented and did some lovely embroidery including lingerie for her trousseau and beautifully handmade baby clothes. Dr Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928 . Its first station was in the remote town of Oodnadatta, where Dr Angus was stationed. He was locum tenens there on North-South Railway at 21 Mile Camp. He took up this ‘flying doctor’ position in response to a call from Dr John Flynn; the organisation was later known as the Flying Doctor Service, then the Royal Flying Doctor Service. A lot of his work during this time involved dental surgery also. Between 1928-1932 he was surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr Angus returned to Nhill and purchased a share of the Nelson Street practice and Mira hospital (a 2 bed ward at the Nelson Street Practice) from Dr Les Middleton one of the Middleton Brothers, the current owners of what previously once Dr Tom Ryan’s practice. Dr Tom and his brother had worked as surgeons included eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. He had been House Surgeon at the Nhill Hospital 1902-1926. Dr Tom Ryan had one of the only two pieces of radiology equipment in Victoria during his practicing years – The Royal Melbourne Hospital had the other one. Over the years Dr Tom Ryan had gradually set up what was effectively a training school for country general-practitioner-surgeons. Each patient was carefully examined, including using the X-ray machine, and any surgery was discussed and planned with Dr Ryan’s assistants several days in advance. Dr Angus gained experience in using the X-ray machine there during his time as assistant to Dr Ryan. When Dr Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon 1933-1938. His practitioner’s plate from his Nhill surgery is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. When Dr Angus took up practice in the Dr Edward and Dr Tom Ryan’s old premises he obtained their extensive collection of historical medical equipment and materials spanning 1884-1926. A large part of this collection is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. In 1939 Dr Angus and his family moved to Warrnambool where he purchased “Birchwood,” the 1852 home and medical practice of Dr John Hunter Henderson, at 214 Koroit Street. (This property was sold in1965 to the State Government and is now the site of the Warrnambool Police Station. and an ALDI sore is on the land that was once their tennis court). The Angus family was able to afford gardeners, cooks and maids; their home was a popular place for visiting dignitaries to stay whilst visiting Warrnambool. Dr Angus had his own silk worm farm at home in a Mulberry tree. His young daughter used his centrifuge for spinning the silk. Dr Angus was appointed on a part-time basis as Port Medical Officer (Health Officer) in Warrnambool and held this position until the 1940’s when the government no longer required the service of a Port Medical Officer in Warrnambool; he was thus Warrnambool’s last serving Port Medical Officer. (Masters of immigrant ships arriving in port reported incidents of diseases, illness and death and the Port Medical Officer made a decision on whether the ship required Quarantine and for how long, in this way preventing contagious illness from spreading from new immigrants to the residents already in the colony.) Dr Angus was a member of the Australian Medical Association, for 35 years and surgeon at the Warrnambool Base Hospital 1939-1942, He served as a Surgeon Captain during WWII1942-45, in Ballarat, Victoria, and in Bonegilla, N.S.W., completing his service just before the end of the war due to suffering from a heart attack. During his convalescence he carved an intricate and ‘most artistic’ chess set from the material that dentures were made from. He then studied ophthalmology at the Royal Melbourne Eye and Ear Hospital and created cosmetically superior artificial eyes by pioneering using the intrascleral cartilage. Angus received accolades from the Ophthalmological Society of Australasia for this work. He returned to Warrnambool to commence practice as an ophthalmologist, pioneering in artificial eye improvements. He was Honorary Consultant Ophthalmologist to Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. He represented the Victorian South-West subdivision of the Australian Medical Association as its secretary between 1949 and 1956 and as chairman from 1956 to 1958. In 1968 Dr Angus was elected member of Spain’s Barraquer Institute of Barcelona after his research work in Intrasclearal cartilage grafting, becoming one of the few Australian ophthalmologists to receive this honour, and in the following year presented his final paper on Living Intrasclearal Cartilage Implants at the Inaugural Meeting of the Australian College of Ophthalmologists in Melbourne In his personal life Dr Angus was a Presbyterian and treated Sunday as a Sabbath, a day of rest. He would visit 3 or 4 country patients on a Sunday, taking his children along ‘for the ride’ and to visit with him. Sunday evenings he would play the pianola and sing Scottish songs to his family. One of Dr Angus’ patients was Margaret MacKenzie, author of a book on local shipwrecks that she’d seen as an eye witness from the late 1880’s in Peterborough, Victoria. In the early 1950’s Dr Angus, painted a picture of a shipwreck for the cover jacket of Margaret’s book, Shipwrecks and More Shipwrecks. She was blind in later life and her daughter wrote the actual book for her. Dr Angus and his wife Gladys were very involved in Warrnambool’s society with a strong interest in civic affairs. He had an interest in people and the community They were both involved in the creation of Flagstaff Hill, including the layout of the gardens. After his death (28th March 1970) his family requested his practitioner’s plate, medical instruments and some personal belongings be displayed in the Port Medical Office surgery at Flagstaff Hill Maritime Village, and be called the “W. R. Angus Collection”. The W.R. Angus Collection is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being an historical example of medicine from late 19th to mid-20th century. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery.

Dip pens emerged in the early 19th century, when they replaced quill pens. They were generally used prior to the development of fountain pens in the later 19th century, and are now mainly used in illustration, calligraphy, and comics. A nib pen usually consists of a metal nib with capillary channels like those of fountain pen nibs, mounted on a handle or holder, often made of wood. Other materials can be used for the holder, including bone, metal and plastic. Generally speaking, dip pens have no ink reservoir; therefore the user has to recharge the ink from an ink bowl or bottle in order to continue drawing or writing. Birmingham, England was home to many of the first dip pen manufacturers. John Mitchell pioneered mass production of steel pens in 1822; prior to that the quill pen had been the most common form of writing instrument. His brother William Mitchell later set up his own pen making business in St Paul's square. The Mitchell family is credited as being the first manufacturers to use machines to cut pen nibs, which greatly sped up the process. Germany 1842 began at the factory of Heintze & Blanckertz in Berlin By 1860 there were about 100 companies making steel nibs in Birmingham, but 12 large firms dominated the trade. Dip pens are rarely used now for regular writing, most commonly having been replaced by fountain pens, rollerball pens, or ballpoint pens. However, dip pens are still appreciated by artists, as they can make great differences between thick and thin lines, and generally write more smoothly than other types of pens. Dip pens are also preferred by calligraphers for fine writing. Richard Esterbrook was a Cornish Quaker from England who saw an opportunity in the United States to manufacture Steel Pens. In 1856 R.Esterbrook traveled to the US to set up shop as 'The Steel Pen Manufacturing Company' where Richard made these steel pens by hand using special tools and machines (mostly that Richard had to invent). In 1858 he was able to establish himself as the sole pen manufacturer in the USA and he changed the company name to 'The Esterbrook Steel Pen Mfg. Co.' The company settled down in Camden, New Jersey. Quality was a key factor in his success. His steel pens were versatile, long lasting, and came in many different styles to fit the varied writing styles of the public. Sadly, Richard Esterbrook didn't see the 'empire' his company was to become as he passed away in Atlanta on October 12th 1895 . in 1896 they started an Esterbrook branch in England to join the ranks of the other main pen manufactures in Birmingham . In 1912 the company had gotten so large that they erected a 5 story building, just to continue manufacturing pens. By 1920 the fountain pen was fast becoming more popular amongst people who were tired of 'dipping.' To meet this demand the company manufactured its first fountain pen. In 1930 the company sought less expensive means of manufacturing pens because gold and 'jewel' tips were too expensive and in this same year they began selling fountain pens in England . The Esterbrook Company began using the metal Iridium which they called 'Durachrome.' To meet the fountain pen demand the company reformed as 'The Esterbrook Hazel Pens Ltd.' In 1940 war had come to strike a blow at the Esterbrook company. On November 19th 1940 their England location was hit by an incendiary bomb destroying half of the location! To make matters worse, when putting out the fire using a human water bucket chain, someone accidentally grabbed a bucket of paraffin and set the place further ablaze. Oddly enough, the company was able to rebuild the structure during the war. However, the government had placed a stipulation that 50% of its capacity was to be used for government related purposes. In 1947 the company bought out John Mitchell and the American branch had already acquired Hazel Pen Co. The company re-formed again as 'The Esterbrook Pen Company.' This is the last company name the dip pen nibs were manufactured under. A box of Steel dipping nibs for writing pensOn Box; Photo of man / R.

This large pastel drawing was created by Dr W.R. Angus in 1925, the year after he graduated as a doctor in South Australia. In 1926 Dr Angus was appointed as Medical Assistant to Dr Thomas Francis Ryan, in Nhill, Victoria, where he extended his experiences in radiology and pharmacy. Eventually, in 1939, he and his wife Gladys moved to Warrnambool, Victoria, with their children. The drawing is part of the W.R. Angus Collection, which includes another of the doctor’s pastel drawings and a box of used pastels. The picture was framed by W.H. Rogers & Co. of North Terrace, Adelaide. The business also framed maps and plans. This pastel drawing is locally significant for being the work of Warrnambool doctor, W.R. Angus. It is part of the W.R. Angus Collection, which is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being a historical example of medicine, administration, household equipment and clothing from late 19th to mid-20th century. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery. The collection includes Army objects, which are examples of items issued to Doctors and Surgeons in the Medical Services of the Australian Army in World War 2. It also includes household items used by Dr Angus and his family from the 1920s in various locations including Warrnambool, together creating an understanding of the furnishing of an early to mid-20th century home.Pastel drawing behind glass in a rectangular wooden frame with an unusual oval wooden matt.

Scarifiers were traditionally used for blood letting, and in folk medicine for the practice of cupping. Spring loaded knives cut the skin, then a warmed metal or glass cup is placed over the cuts. As the air inside the cup cools, it creates a vacuum drawing out the "bad" blood. The process is also related to the ancient medical theory of "humors". This theory dates back to the Hippocratic tradition and persisted through to the mid-19th Century. According to this theory, the body had four "humors", "airs" or "elements" which neeed to be kept in balance. Any imbalance could cause illness and this was often explained in terms of excess fluids. One prescribed treatment was to remove the excess blood which would restore the balance.Square, solid brass object with lever to release blades underneath.Etched on side: Mundy / Londonmetal, blades, bloodletting

The Mark II Pilot Balloon Slide Rule was made of wood laminated with heavy white plastic with a length of 24.5-in. and width of 2.5 inches. Mark II rules were manufactured in Australia by W & G (Melbourne). The W & G rule differs only slightly from the English A. G. Thornton LTD rule. The W & G rule uses serif fonts and has some fiducial marks that the English rule lacks. Exact dates of production are not known but the MK II is known to have started production by 1927. The printed scales are engraved in the plastic faces. The slide rule has 4 captive cursors (glass windows and brass guides) that ride in slots on the top and bottom edges. Each can be moved independently of one another. The cursors are missing from this item. Brass knobs at both ends of the slide facilitate its movement. The case is fabric covered wood with felt lining. No known history for this item as located in a property after purchase. The Pilot Balloon slide rule is used to convert the observed azimuth and elevation readings into wind velocity and direction records. The use of slide rules was abandoned with the wide spread adoption of computers and programs to do the calculations, as well as the decline in the use of optical pilot balloon theodolites.Made in Australia by White & Gillespie (Melb) Pty Ltd. Established in 1910, the firm was involved mainly in printing plate manufacture, but during the Second World War it manufactured a variety of navigational aids and range finding devices for the military. About 250,000 instruments were made during that period. After the war the company produced, among other items, drawing instruments and slide rules. The case is fabric covered wood with felt fabric lining containing a long black laminate ruler with numerous white markings and numbers. Top of the ruler is in three sections with the centre section movable by small gold metal knobs at either end. This slide rule contains a engraved notation on the rear face "IMPORTANT.

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. A thermo-hygrograph measures and records both temperature and humidity. It produces a continuous record by drawing ink traces on a paper chart held in revolving cylinder. Humidity is measured by shortening or lengthening of specially treated human hair. Temperature is measured by means of a bi-metallic strip. This particular instrument is a seven day recorder. The instrument is driven by clockwork. Serial number 10186 which probably dates from about 1960. The chart indicates it was last used in March 1979.Used for bushfire research.Clockwork Thermo Hygro GraphCasella London 10186 Made in England Research Branch. Forests Commission Orbostbushfire
