This item wasused before diesel, electric and battery drilling apparatus were used by farmers, and other trades requiring a portable yet reliable method of drilling holes. As this item is a 3/4 inch hole drill it would be suitable for fencing and providing holes for structural studs. As with all outdoor farm equipment, man power was required (be it the farmer or farm hands). Fitness of the operator was at a high standard but protective gloves were not highly thought of as it was before occupational, health and safety regulations became mandatory over all manual handling activities, be they on rural properties or town/city factories. This period was one where the male ego was at its pinnacle i.e. the harder the tasks the more of a man was required. Hard manual work was not only the "way to go" but also a necessity. Evolution of cheap portable electric/battery powered tools opened up a more efficient method available, especially to those with less muscle strength. This item personifies the rugged environment of the rural workplace. The Kiewa Valley with its main emphasis on farming and grazing provided ample opportunity to use this construction implement. The manufacturer being a Scottish tool company is very significant in the era when this hole maker was in high demand. British steel products were of high grade and had a good record of reliability. The reliability of any tool was a solid factor for farmers and tradesmen in this semi-isolated region (Circa early 1900s) within the Kiewa Valley and its regional area. This factor,although not as crucial, post 1960s, when Asian manufacturers entered the market place and produced cheaper tools and transportation and supplies was more frequent and reliable, the need for the more expensive British made tools diminished considerably. After the influx of tradesmen from war torn Europe (post 1945) and the increased availability of tradesmen in the Kiewa Valley and its region the price of tools was and still is not as crucial and the cost of all required tools has become a minimal part of the equation. It is only with the emerging younger trades person, farmer and grazier, who have more, "one eye on production costs" and no "old ties to the motherland" inert mind set that quality tools such as this auger and other hand tools "must be made to last a life time" is no longer part of the modern work environment.This cast iron, hand operated Auger has a short barrel shaped cylinder at one end (known as the "Eye") and at the other end a Helical screw blade (screws the cutting edge into wooden material, thereby creating a hole 3/4 inch diameter in the wood) . The barrel section at the top permits a metal or wooden leverage plank to be inserted. The main rod has a 180mm long cutting/screw blade running from the bottom up towards the "eye" end. From the end of the screw blade to the handle is 380mm and cylindrical, but this changes at 550mm from the "eye" end to a 14mm x 10mm rectangular shape shaft.This shaft end is welded to the "Eye".On the shaft below the "eye" is stamped " MATHESON GLASGOW" on the front side and a spade (cards) symbol on the back.auger, hand drill, fencing, tool, rural trades, brace & bit

The Victorian Gold Jubilee Exhibition, held at Bendigo from 13 November 1901 to 14 May 1902. The courts were numbered from one, or had titles like “Machinery”, “Agricultural”, “Naval & Military Court” and “Art”. The female visitors to the Exhibition were able to view exhibits deemed suitable for the fairer sex and located within their own “Women’s Court”. There were exhibits such as “Parasols & Umbrellas”, cotton and haberdashery from Manchester and Staffordshire, “Corsets & Embroideries” from Paris. The most valuable exhibits were mining machinery such as Taylor Horsfield’s £850 “Air Compressor & Rock Borer”. “Bohemian Glassware” brought down from Sydney was valued at £600. The profits from this Exhibition were used to fund the sculpture known as the Gold Monument, which still gazes along Pall Mall (from the McCrae Street end). The Exhibition’s Cash Book shows payments, which totalled £1160, were made to then up and coming sculptor C.D.Richardson. Recently a City of Greater Bendigo staff member used both these volumes to write a detailed report about this monument, for Heritage Victoria.Carol Holsworth Collection: Small book Souvenir, 29 pages plus cover; each page. has a photo of the exhibit.

The Strowger switch is the first commercially successful electro-mechanical stepping switch telephone exchange system. It was developed by the Strowger Automatic Telephone Exchange Company founded in 1891 by Almon Brown Strowger. In 1912 Australia's first automatic telephone exchange was installed at Geelong. Victoria. The exchange equipment was Strowger Automatic telephone apparatus, manufactured by the Automatic Electric Company, Chicago USA. This is a useful research tool for the history of telephony.A 96 pp bound book with a dark brown cover.

This bottle was used in the pharmacy of Harry London of Warrnambool. Born in England, Harry London arrived in Victoria in 1883 and worked as a chemist in Ballarat and Euroa. In 1891 he went back to England where he studied dentistry. In 1891 he came to Warrnambool where he bought the pharmacy business of the late William Nettleton. He occupied the Nettleton building in Liebig Street (95 Liebig Street today) until 1896 when he erected new premises at the south west corner of Liebig and Koroit Streets. At that time he was the only chemist in Warrnambool using a Pasteur filter for water to make up his medicines. In his dentistry business he used gas, chloroform and cocaine as anaesthetics. The making of dentures was his speciality. In 1904 he was the owner of the only set of Rontgen X Ray apparatus in Warrnambool. In 1905 his shop was the first in Warrnambool to have electric lighting installed. This item is a valuable one as it has local provenance. It came from the pharmacy business of Harry London, a prominent Warrnambool chemist in the late 19th and early 20th centuries. Harry London mementoes such as this are comparatively rare. This is a chemist’s glass bottle with a rectangular body, a circular neck and a rounded top. There is no stopper and the bottle is empty. The top has a small chip. The name of the chemist is embossed on the front of the bottle in an indented section of the glass. The bottle is slightly scratched and discoloured from the original contents. On front of bottle: ‘H. London Chemist & Dentist Warrnambool’ On base: ‘M’ On the body of the bottle: ‘31’ harry london, chemist, warrnambool chemists, history of warrnambool

This bottle was made by the Whitall Tatum Glass Company in New Jersey, U.S.A This company operated from 1806 to 1938. The bottle was used by Harry London in his Warrnambool pharmacy. Born in England, Harry London arrived in Victoria in 1883 and worked as a chemist in Ballarat and Euroa. In 1891 he went back to England where he studied dentistry. In 1891 he came to Warrnambool where he bought the pharmacy business of the late William Nettleton. He occupied the Nettleton building in Liebig Street (95 Liebig Street today) until 1896 when he erected new premises at the south west corner of Liebig and Koroit Streets. In 1896 London was the only Warrnambool chemist using a Pasteur filter to make up his prescriptions. In his dentistry business he used gas, chloroform and cocaine as anaesthetics. The making of dentures was his speciality. In 1904 London was the owner of the only set of Rontgen X Ray apparatus in Warrnambool. In 1905 his shop was the first in Warrnambool to establish electric lighting. This bottle is of importance as it is one of the few items we have associated with the prominent Warrnambool chemist, Harry London. It is comparatively rare so it is of some local significance. This is a glass bottle with a rectangular base with curved ledges, a circular neck and a circular moulded top. There is no stopper and the top is badly chipped. The name of the chemist is embossed on the front in an indent in the glass. ‘H.

Electroconvulsive therapy (ECT) was invented in Italy in the late 1930s. ECT is a medical treatment most commonly used in patients with severe major depression or bipolar disorder that has not responded to other treatments. Psychiatrists had already discovered that inducing seizures could relieve symptoms of mental illness. Before ECT, this was done with the use of chemicals, usually one called Metrazol. More can be read here: http://theconversation.com/electroconvulsive-therapy-a-history-of-controversy-but-also-of-help-70938 This machine was used both at Aradale Mental Hospital and J Ward. The object is significant because it is a well preserved instrument that illustrates the medical apparatus used at both Ararat Mental Hospital and J Ward for the treatment of mental illness.A metal instrument. The front contains three knobs, two switches, and power button. Two fully intact electrical cords - One leads to the paddles used on the patient: One used to attach to the electric source [power point]. Paddles are made of hard plastic and stainless steel metal.

A telegraph or Morse key, sends a series of electrical signals down a telegraph line or via radio frequencies; the signals are interpreted as Morse code, a binary form of language constructed of 'dots and dashes', combinations of which correspond to letters of the alphabet. The motion of the key acts to complete an electrical circuit between the sender and receiver, producing a short pulse 'dot' or longer 'dash,' the space between the code indicates a broken current or wave.Device used to transmit telegraphic messages in Morse code through the manipulation of electric signals. The metal 'key' sits in a central bracket on which it moves up and down aided by a spring, controlled by an operator pushing the black Bakelite knob on the protruding end of the device. The motion presses the key onto a circular metal disc, completing the circuit and sending an electrical pulse to the receiver. The apparatus is secured to a wooden base with wires attached to the terminals; a cut out section of the base suggests wires may have entered through this area, attaching to a battery.Printed ink on base: "PMG"telegraph, telegraphist, morse code, mechanisation
