Henry J. Hall was an teacher Freehand Drawing and Model Drawing at the Ballarat School of Mines. In 1889 he reported to the Ballarat School of Mines Council that this class was never established for the cultivation of Art (as generally understood) or the making of pictures but with an idea of assisting artisans - of both sexes - and persons connected with mechanical industries, in acquiring lightness of hand, and facility in the use of a black-lead pencil so as to be able to place legibly and intelligibly upon a sheet. For many years Henry Hall advertised private tuition in Drawing, Painting and Perspective, at 'Ferndale', 25 Eyre Street. Handwritten letter on paper with the address 'Ferndale, 25 Eyre Street, Ballarat' printed at the top. The handwritten letter is from Henry J. Hall to Andrew Anderson, President of the Ballarat School of Mines. Handwritten in ink "March 19th 98 Andrew Anderson Esq President School of Mines Dear Sir I am informed by the registrar of the School of Miens that you are desirous of despensing [sic] with the services of Drawing Instructor at that Institution. The reason assigned being dis-satisfaction expressed by the inspector regarding "the quantity and quality of the freehand work done during the year. Before any definite action is taken, might I ask in justice to myself and the students whose work is thus maligned, that I be allowed a personal interview with Mr Monkhouse in order to ascertain the grounds of his complaint, and afford me an opportunity of vindicating my position. I have the honor to remain, respectfully yours Henry J. Hall." Written and circled in red ink "168" ballarat school of mines, henry j. hall, henry hall, andrew anderson, drawing, art

Jim (James Bernard) Williams, who was the owner of this manual, was a long-time resident of Warrnambool having the opportunity to work at two notable historical businesses of the town. The first, Cramond & Dickson a drapier store established around 1852-1855 and which remained a store that traded under the same name for the longest in Victoria, before it closed its doors in 1974. The second business was Fletcher Jones a highly successful textile and clothing Australian business. Some of Jim’s spare time was devoted to the model ship making which would conjure up many fascinating stories of maritime history. In addition to Jim witnessing the tail end of ships at port in Warrnambool, his "father was as sea captain and operated his vessel in Bass Strait coastal trade between Tasmania and Victoria". The intricately detailed model made by Jim is full of precise detail. The manual and the blueprints held by Flagstaff Hill Maritime Village also reflect the intricate process and devotion to the task completed by Jim. The history of the shipwreck and maritime stories of the Victorian Southwest coast surrounding Warrnambool would have continued to inspire his passion. Three photos of the model and Jim, like the photo of Harold T. Bodkin in the manual, attest to the enthusiasm and enjoyment that was gained by him through this hobby. The manual opens to a photo of “Mr. Harold T. Bodkin adding finishing touches to model of the “Sovereign of the Seas”. The “Forward to Reader” which is on the next page is written by “E. R. HAAN, Technical Editor, Popular Mechanics Magazine. The forward explains the methodology used to achieve the fine detail that is part of the body of the model, by “applying imitation carvings”, and is cited as “a museum type of model”. The following page “Blueprints and Craftmats on the ‘Sovereign of the Seas’” discusses the availability of a set of blueprints to purchase separately. Followed by a description of the moulding process for the “miniature carvings”. “Historical Notes of Interest on the “Sovereign of the Seas (1637)” follow on the next page. The manual is divided into the following parts from pages 8 to 71: “Part I – Shaping the Hull/Part II – The Rudder, Quarter Galleries and Gunports/Part III Wales, Gunport Covers and Initial Ornamentation/Part V – Beakhead Decoration, Bulkhead and Rails, Etc./Part VI Carvings, Lanterns, Knights, Bitts and Painting/Part VII – Details of Mast Construction/Part VIII – Standing Rigging/Part IX – Running Rigging and Final Details. All of these instructions include photographs and detailed graphs. Then instructions on “How to Read and Use Ship-Model Drawings”, “The Shop-Model Maker’s Tools”, and “Simplified Ship-in-a-Bottle”. This is finished off with “Helpful Hints….” And numerous pages of advertising. Some adverts include aids for completing the “Sovereign of the Seas” model. Part I uses blue and black ink to illustrate a dramatic picture of the “Sovereign”, otherwise all print is in black ink on buff paper. This book in significant to the collection as it was donated along with other tools and blueprints which have been used by the donor of the "Sovereign of the Seas" model ship. It also connects with the wider community in that it is related to historical maritime interest and the donor, Jim Williams is also connected to other significant retail and manufacturing businesses of the past in Warrnambool. This manual has been covered with brown paper, including an extra strip for the spine. The front has a watermark at the top middle, some pencilled compass circles segmented into eight parts across the area and a small amount of script writing. The back also has the same type of compass circles and some other small shapes. There are also grease marks. The cover has a patina adding to variations of colour to the paper indicative of the book being handled often. The title page reads “Sovereign of the Seas” in an Old English font. This is followed by a lithograph print around 1 inch square of a ship at full sale. By HAROLD T.

(Source: The First One Hundred Years by R.S. Medew and I.M. Bowman - A History of The Medew Family in Victoria - page 11 extracts) - Charles Turner Medew (1829-1915 ) arrived in Victoria from England in 1857. He eventually settled in Ringwood as the original purchaser of Crown Allotment 32, Section C, where he built his own home in 1888 and became well known locally "for his fine building work and stone masonry." ... "In his retirement, Charles Medew experimented with model helicopters. About 1910, at the age of 80 years, he was able to raise these helicopters to such a point of efficiency that, just with an elastic wound propeller, when released they could fly upwards to the height of the large oak trees." ... "(Also) In 1910, Charles obtained plans and made a model of the Wright Brothers' biplane entirely of wood, with laminated wood propeller and driven by twisted elastic bands." This model remained in his workshop for many years after his death and with his family's permission was eventually placed in the Melbourne Science Museum.3 pencil drawings showing assembled parts and sectional views of a model helicopter.

Children used slates to practise writing letters and numbers. They sometimes used their slates to play games when not learning their lessons Early models of small, hand-held chalkboards were slates encased in a wood frame to keep the slate from breaking. Pencil and paper were available but paper was very expensive. Using a small, hand-held slate meant that a child could practise writing, erase and write again without having to consume expensive paper.This item is an example of early educational equipment and can be compared to modern school equipment.A double-sided rectangular-shaped school slate with a wooden frame.Chalk markings - number sentences.

Multiplex mechanical stereoplotting equipment was used at the Army Survey Regiment, Fortuna Bendigo. c1950s. Multiplex equipment was imported from the UK in 1951 and introduced in the following year, to accelerate map production output covering CMF training areas at 1:25,000 map scale. Multiplex plotting was a productive advancement replacing the ‘Arundel’ method of graphical plotting planimetric detail that was expensive and slow, especially in timbered mountainous terrain. Air photos were made into small diapositives and mounted on racks in the exact position relative to when the aerial photos were taken. The technicians operated the Multiplex in a darkened room, with one photo projected with a green filter and the other through a red filter to form a 3D view of the overlapping photos. The 3D model projected onto a platen, which was a small platform that was raised up and down. The technician viewed the 3D image with special glasses fitted with red and green lenses. In the centre of the platen was a small pinhole that served as a floating mark, with a vertical pencil located exactly below the pinhole. This tracing table was moved to follow the topographic feature or contour line and draw it on the paper underneath.

This is a set of six photographs of stereoscopic equipment and personnel at the Army Survey Regiment, Fortuna, Bendigo, c1950s to c1960s. The stereoscopes shown in photos .1P and .2P were used to stereoscopically view and interpret features in overlapping aerial photographs. The stereoscopic plotters shown in photos .3P and .4P were used to stereoscopically plot topographic detail from overlapping aerial photographs using a pantograph arm with pencil onto a controlled plotting sheet. The Ryker Model PL-3 Wernstedt-Mahan type stereoscopic plotter shown in photos .5P and .6P was used for precision contouring, planimetry and profiling. It was a comparatively simple stereoscopic mapping instrument designed to use ordinary contact prints of aerial photographs. It provides for plotting on a constant scale and approximate tilt correction but does not provide refinements such as correction for lens distortion. The plotter in Photo .6P does not have its pantograph arm attached. These plotters pre-date the Wild B9 and B8 stereo plotters introduced in the 1960s.This is a set of six photographs of stereoscopic equipment and personnel at the Army Survey Regiment, Fortuna, Bendigo, c1950s to c1960s.

Pencil drawing from a sketch book by Walter Withers. Held by the National Gallery of Victoria. Featured on p82 of "Pioneers and Painters". The figure study is reproduced in Wither's 'The Drover' (1912) held by Bendigo Art Gallery. The model was Mr W. J. Capewell, the Eltham Butcher.This photo forms part of a collection of photographs gathered by the Shire of Eltham for their centenary project book,"Pioneers and Painters: 100 years of the Shire of Eltham" by Alan Marshall (1971). The collection of over 500 images is held in partnership between Eltham District Historical Society and Yarra Plenty Regional Library (Eltham Library) and is now formally known as the 'The Shire of Eltham Pioneers Photograph Collection.' It is significant in being the first community sourced collection representing the places and people of the Shire's first one hundred years.Digital image Print (x2)horse, pioneers and painters, sepp, shire of eltham pioneers photograph collection, sketches, the drover 1912, w.j. capewell, walter withers, walter withers sketch

This collection of 12 photos was most likely taken in 1980. The photos were most likely taken in Cartographic Squadron’s Ante Room, the Attic and small offices on the top floor of Fortuna Villa. The computer based Editwriter typesetting system was introduced in 1975 as a replacement to the aging Fotosetter machine. It was operated by a specialised technician, who generated a large variety of map type styles and sizes quickly and reliably, as well as text panels. CPL Richards performed this task for several years and in photo .1P and .2P is reading off a type order next to the computer monitor. Output on Copy proof adhesive backed stripping type film replaced messy wax and spray adhesives in 1978. The Editwriter capability supported all RASvy units and contractor type setting requirements. Scribing was the cartographic process of drafting features such as drainage, relief, vegetation, roads and culture on specially coated map reproduction material. The cartographic technician scribed out the map feature such as a contour to a specified line width on the map sheet, using a tool affixed with a sapphire tipped cutter. The quality control edit (Proving) stage of map production was the first opportunity to inspect a proof of the map independently and systematically. Proving tasks were carried out by technicians conversant of the map product specification and task requirement, however, was not involved in its production. Corrections were identified, marked up and sent to back to the correcting section or contractors. Terrain Embossing was a manual map production technique to produce hill shading on medium to small scale graphics and air charts. SPR John Martin is seen in photos .8P to.10P using a fine embossing metal stylus to push down on the drainage impression on a thin malleable opaque plastic material (AK Poligraphy). Ridge lines were then pushed down using the contour impression as a guide, on the opposing side of the AK Poligraphy to create a 3D plastic model terrain effect. The map impression was sprayed with white paint and photographed to create a contone tone hill shade. SPR Gina (Coore) Neilson is seen in photo .11P washing a contone positive of a land mass in a solution. The contone components were registered to the map sheet, as shown in photo .12P and masked using an air brush and a halftone negative was then created. The terrain embossing method of producing hill shading was more efficient to produce than previous specialised artistic methods such pencil/eraser and air brush. Furthermore, a more consistent enhancement of terrain on charts was achieved between technicians.This is a set of 12 photographs of Cartographic Squadron performing four map production tasks at the Army Survey Regiment, Fortuna, Bendigo c1980. The first ten photographs were on 35mm negative film and were scanned at 96 dpi. Photos .11P and .12P were on photographic paper and scanned at 300 dpi.
