This book was a text book used by Arthur Gregory, the test room technician at Warrnambool Cheese and Butter Factory in the 1930s. He tested the suppliers’ milk and cream for butterfat percentage in order to determine the payment to the suppliers. Arthur Gregory later became the manager of Jays Laundry in Fairy Street. In the 1930s Arthur Gregory boarded at 28 Spence Street in Warrnambool. This boarding house was run by May Taggart, the wife of Sam Taggart, a Warrnambool tailor. Les O’Callaghan was also a boarder there and it was through his contact with Arthur Gregory that he obtained the position of laboratory technician at the Warrnambool Cheese and Butter Factory. Les O’Callaghan remained for over 40 years at this factory (leased at that time by the Kraft company) and was very important in the development of laboratory techniques used in the dairy industry. The Warrnambool Cheese and Butter Factory was established at Allansford in 1888 and is still in production today, operated by the Canadian firm of Saputo. This book is of interest because of its connection to Arthur Gregory, a test room technican at the Warrnambool Cheese and Butter Factory in the 1930s and to Les O’Callaghan, the Laboratory Manager and Microbiologist at Warrnambool Cheese and Butter Factory for more than 40 years. This is a hard cover book of 822 pages. It has a blue cover with gold lettering on the spine. It has 29 chapters, an appendix, a bibliography and an index. It has many black and white illustrations and drawings. The spine is slightly scuffed. The inscription is handwritten in pencil. ‘A.S.Gregory 28 Spence Street W’bool’ warrnambool cheese and butter factory, arthur gregory, warrnambool, les o’callaghan, warrnambool, history of warrnambool

This Babcock tester was used in the laboratory at the Kraft cheese factory, Allansford. When it was superseded it was passed to one of the users of the machine, Les O'Callaghan, president of the Warrnambool & District Historical Society who placed it in the historical society collection. In 2009 when the historical society premises were upgraded there was insufficient room to store the tester so it was donated to Cheese World Museum. The machine was used to test the butterfat content of milk. Prior to dairy factories coming into existence farmers made butter individually on farms. There was no need for milk testing until farmers supplied factories for payment. Payment was based on a gallon of milk weighing 10lbs (pounds) and this led to richer milk, containing a high degree of butterfat for use in buttermaking, being paid at the same rate as lesser quality milk. In 1890 Stephen Moulton Babcock, an American professor at the University of Wisconsin-Madison, developed a method of determining the amount of butterfat in milk, thus providing a standardised and fairer system for payment. Babcock Test Process 1. 18 grams of milk (17.6ml) was put into a test tube 2. The same amount of sulphuric acid was added 3. A centrifuge at 50ºC was rotated at more than 900 revs per minute 4. The fat floating on top of the liquid in the test tube was measured The Babcock Test provided fairer compensation to farmers and also helped produce a consistent product for consumers. It also allowed for selective breeding when dairy herd testing evolved. ‘The Babcock Test is so simple that it can be used by any careful person, and it is inexpensive to operate. From the very beginning it was so complete in every detail that no change has had to be made in it.’ (Babcock Test http://www.en.wikipedia.org/wki/Babcock_test 31 March 2009) Round green metal container with opening lid.

In 1890 D. Babcock invented a test for measuring the amount of butter fat in milk, either on the farm or in the dairy or creamery. Samples of milk were put in the glass vial and then spun (by cranking the handle) causing the cream to separate from the non-fat milk thus determining the percentage of cream in the milk. The product was then priced accordingly.Dairy farming in the Kiewa Valley was the main industry with farmers keen to test the quality of their milk before selling it. This centrifuge enabled them to test the amount of milk and cream being produced by their herd. This '1903 Butter Fat Tester' made 100 turns per minute. Early hand crank centrifuge for measuring the butterfat content of milk in the farm dairy or creamery. It has 4 brass / copper removable canisters with glass vials and tubes that fit inside. The glass vials bulge at the bottom and are marked with measurements 1, 2 etc.Numbers on the glass vialsmilk and cream tester, dairy farming, centrifuge

Early settlers had to be self sufficient, growing their own vegetables, making tools and clothing and usually had a house cow to produce their milk supply. .All the buttermilk separated from the butterfat had to be rinsed out. This would improve texture and flavour, and also help the butter keep well, since milk turns rancid more quickly than fat alone. Salt was usually mixed in at this stage - for flavour and preservation. The rinsing could be done simply by washing in water, followed by draining, salting and working or "kneading" the butter with a pair of wooden butter pats, or with bare hands. c1880 A pair of wooden butter patspioneers, early settlers, market gardeners, moorabbin, brighton, bentleigh, cheltenham, milk, dairy farmers, butter pats, dairy cows

Lavers Hill Cheese Factory operated from 1906 until about August 1913. It consisted of a factory and a residence, with the managers B. Philbrick, D. McRae and D. McDonald. The ledger, covering the period 1910 until 1913 when the factory closed, deals with cheese sales, local sales, milk purchases and journal entries for this period, as well as wages, cartage and other operating expenditure. The Lavers Hill Cheese Factory closed when it became more advantageous to send their cream into Colac. Ledger.
