Manufactured Glass, bottle 'Kruse's Magnesia', 20thC
Johann August (John) Kruse was instrumental in the development of the pharmaceutical industry and pharmacy training in Victoria. He was a driving force behind the creation of the Pharmaceutical Society of Victoria and was appointed a founding member of the Society's inaugural council in 1857. He manufactured many pharmaceuticals and health products such as mineral waters and 'Kruse's Fluid Magnesia' (1863) which is still in use today. He later went on to produce insecticides and dynamite, then established his own analytical chemistry service. In 1878 Kruse established Victoria's first pharmacy training facility - the Melbourne School of Pharmacy. There pharmacy apprentices were taught chemistry, botany, materia medica and Latin, while country students could study by correspondence. The School was endorsed and monitored by the Pharmacy Board of Victoria to which Kruse was appointed in 1880. Kruse's pharmacy school was the forerunner of the Victorian College of Pharmacy, Monash University, which remains Victoria's only pharmacy training institute. In 1853, shortly after qualifying as pharmacist at the University of Göttingen, Johann August (John) Kruse, moved to London. The medical practitioner Dr S. Weil sent Kruse to Victoria, Australia to manage a new pharmacy and tobacconist's shop which he was having built at 136 Bridge Rd in Richmond. In 1856 Kruse opened a second pharmacy 'John Kruse and Company Chemists and Druggists' at 207 Bourke Street. 1857 the Richmond shop was destroyed by fire, so all pharmaceutical production was moved to the Bourke St premises and later to his new location at 184 Bourke St.. Kruse was forced to sell his business in 1868 to Felton Grimwade and Company and work for them as manager of their chemical works. By the early 1870s he had regained financial independence so left the company to establish his own businesses again. He opened up a pharmacy at 31 Swanston St and in c1874 leased Victoria's premier natural springs, Clifton Springs, on the northern side of the Bellarine Peninsula, where he established a bottling plant. Suspensions of magnesium hydroxide in water, often called Milk of Magnesia, are used as an antacid to neutralize stomach acid, and as a laxative. Milk of magnesia is sold for medical use as chewable tablets, capsules, and as liquids having various added flavours Kruses Fluid Magnesia 300ml Extralife Kruse’s Fluid Magnesia, Magnesium supplement. Rapidly absorbed, easily digested. Improves general well being, corrects magnesium deficiency. Helps relieve indigestion, when due to acidity.

Photograph - digital, LJ Gervasoni, Murtoa Stick Shed 00031, 13/08/2011
From the Victorian Heritage Register statement of significance H0791 The Marmalake/Murtoa Grain Store, originally the No.1 Murtoa Shed, is located within the Murtoa Grain Terminal, adjacent to the grain elevator tower and railway line. The shed is 280m long, 60m wide and 19m high at the ridge with a capacity of 3.4 million bushels. The hipped corrugated iron roof of the shed is supported on approximately 600 unmilled hardwood poles set in a concrete slab floor and braced with iron tie rods. These poles are the reason for use of the term "stick shed". With its vast gabled interior and the long rows of poles the space has been likened to the nave of a cathedral. An elevator at one end took wheat from railway trucks to ridge level where it was distributed by conveyor along the length of the shed, creating a huge single mound of grain. Braced internal timber bulkheads on either side took the lateral thrust of the wheat, and conveyors at ground level outside the bulkheads took wheat back to the elevator for transport elsewhere. Wheat had been handled in jute bags from the start of the Victorian wheat industry in the mid nineteenth century. Bulk storage had been developed in North America from the early 1900s. NSW began building substantial concrete silos from 1920-21. In Western Australia, farmers' co-operatives, who had to supply their own bulk storage from 1934-5, pioneered the use of low-cost horizontal sheds of timber and corrugated iron for bulk storage. Following its establishment in 1935 the Victorian Grain Elevators Board (GEB) planned a network of 160 concrete silos in country locations, connected by rail to the shipping terminal at Geelong. By the outbreak of the Second World War there was a worldwide glut of wheat, and Australia soon had a massive surplus which it was unable to export. Only 48 silos had been established under the Victorian Silo Scheme so far, and wartime material and labour restrictions prevented progress with this scheme. The storage deficit had become an emergency by 1941 as Britain obtained its imports from North America, rather than over the lengthy and difficult shipping route from Australia. In 1941 the GEB, under chairman and general manager Harold Glowrey, proposed large temporary versions of the horizontal bulk storage sheds already in use in Western Australia. The proposal was approved by the Victorian Wheat and Woolgrowers Association, who considered the use of shed storages as a longer term proposition. After initial resistance from the Australian Wheat Board, some of whose members represented wheat bagging interests, the Commonwealth and Victorian governments agreed to split the costs, and Murtoa was chosen as a suitable site for the first emergency storage. The main contractor, Green Bros, commenced work on the No.1 Murtoa Shed in September 1941, deliveries of bulk wheat began in January 1942, and the store was full by June of the same year. In the following years the Council for Scientific and Industrial Research (later CSIRO) conducted valuable research and experiment on the impacts and control of insect pests at the Murtoa No.1 shed. With these discoveries, and the development of more effective pesticides, use of the No.1 shed and the larger No.2 shed, erected in 1942/43, continued for many years. The No.2 shed was demolished in 1975. By the 1990s, pest resistance to pesticides and requirements for both pest free and insecticide free grain rendered open storage of this type unviable. The No. 1 store was also becoming increasingly expensive to maintain, and its use was phased out from 1989.Image of the Marmalake/Murtoa Grain Store which is of historical, architectural, scientific (technical) and social significance to the State of VictoriaDigital colour image of the interior of the Marmaduke .

Can Mortein Powder, late 1870s to early 1920s
The can(product) of powdered Mortein was used throughout Australia and especially in rural regions where environmental conditions of crops, cattle and other livestock resulted in greater amount of "invasions" from insects. The eradication of unwanted invaders into the homestead required either manual extermination or a relevant poison which in low doses would not affect humans. Fly squats were still a good measure of eradication of flying pests however those lurking in cupboards or "hard to get at" locations needed a method, such as the Mortein powder to do the deed. This product and especially this can was used at the fore front of pest eradication. Powders and pellets are still in use 100 years later and the core ingredient is still environmental friendly and meets health conscious modern Australians. The basic product has survived the passage of time and was invented by a German immigrant to Australia in the late 1800s.This can and what it represents to rural households and outhouses, is in some ways immeasurable to the peace, health and tranquility within the household of all the families within the Kiewa Valley. Although small in size the relief of those within the sanctity of the home from annoying pests is enormous. The relief not only physical but also mentally to those residents, from the sometimes grueling and painful rural existence in a "sunburnt" countryside cannot be truly expressed in words. Kiewa Valley residents are part of the sometimes harsh rural environment where the introduction of helpful products such as this powder are noticed and used more prolifically. Any product, especially invented within Australia, which allows for a easier existence is of a great significance.This small cylindrical can contains powder of crushed the chrysanthemum flowers(pyrethrum extract) and has two circles of small circular perforations in the lid (to allow contents to be sprinkled onto other surfaces). It is constructed of mild steel with both ends crimped onto the main cylinder. A paper information label has been adhered to the outside of the cylinder.Printed on the outside label is: 1st line "MORTEIN!" 2nd line "THE GREAT INSECT DESTROYER" underneath "(Registered)" and underneath "It is without doubt the best and most reliable Insect powder in the World" underneath this line "In order to use Mortein with profit it is best to get a Mortein spreader through", next line "which by pressure of the hand the powder is ejected and well diffused." An inflection mark appears over the e in "Mortein" as to signify that the word "mort" is french for (dead) and the "ein" is german for "one". The word "mortein" therefore is diffused and translated into "dead one". A thin line separates the above from the list of insects which the powdered contents will kill together with the suggested application targets.

LTD., MELBOURNE," Below is "Sole Proprietors"natural insecticide products, environmentally friendly products, household pest dispensers, australian inventions
