non-fictionAn autobiography of Bob Whan, born in Wodonga on 5 January 1933, into the fourth generation of the Whan family in Wodonga. As part of a varied career, he became a member of the Australian Labor Party and represented the Division of Eden-Monaro in the House of Representatives from 1972 to 1975. He died on 4 October 2015. This book describes his childhood and student years, his impact on the wool market in Australia with the introduction of objective measurement, the social and political changes he witnessed, his philosophies on life (which may surprise some) and the highs and lows of a varied career. There is serious thought, plenty of humour, particularly with the characters described, and above all the memories and recollections of someone intimately involved in many aspects of Australian life. bob whan, robert whan politician, whan family wodonga

a small book of 21.5 cm; 160pnon-fictionDrawing on a wide range of theoretical insights and primary sources, "The Unforgiving Minute" offers an original interpretation of Australian history. It examines time telling from the convict era to the 1990's. As the convict era drew to an end, the colonial governors looked to clocks as the mechanical policemen of an emerging free society. Fifty years later, as railways and telegraphs began to spread across the land, and pocket watches appeared on the waistcoats of working men, colonial society began to keep stricter hours of work and play, and to teach its children the virtue of punctuality. In the early 20th century, punch clocks and time-switches laid the basis for new patterns of work in the factory and the home. Now, in the 1990s, the "faceless clocks" in computers and automated control systems have created a "postmodern" time regime that is both more flexible, and more demanding, than its predecessors. time measurements -- social aspects -- australia -- history, clocks and watches -- social aspects -- australia -- history, australia -- social conditions, graeme davison

This instrument measures elevation by sensing minute changes in barometric air pressure relative to a fixed datum point at sea level or a known elevation, such as the starting point of a major town during a road survey, and has an accuracy of +/- 20 feet when used in experienced hands. The finely divided scale around the perimeter of the face is marked from 0 to 6000 feet elevation and 25 to 31 inches of mercury (Hg) for barometric pressure The single fine counter-balanced hand or pointer rotates anti-clockwise with increasing elevation and decreasing pressure. The label "compensated" indicates that the instrument is constructed to compensate for the effect of temperature changes on the accuracy of readings.

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.

A prismatic compass is a common navigation and surveying instrument which was used extensively by the Forests Commission The compass most commonly used to run a traverse line. The compass calculates bearings of lines with respect to magnetic needle. A magnetic deviation correction was needed to convert the reading to a true bearing The compass could also determine angles between the traverse and waypoints (such as hilltop features). Commonly used for navigation. Largely replaced by modern GPS technology.Ex Army WW2 prismatic compass with leather case and strap. Rugged design and made of metal the internal compass plate floats on oil to help it stabilise The user lines up the direction of travel with the hair sightline in the fliptop cover and readings are taken through the viewfinder prism (hence the name).forest measurement, surveying, forests commission victoria (fcv)

This pocket stereoscope was used to view a pair of separate and overlapping aerial photos as a single three-dimensional image. It was small and could be easily used in the field. Larger, mirror stereoscope were also available in some offices. The aerial images were used to map forest types, timber stands, new roads and tracks, firebreaks, boundaries of timber harvesting, plantations, bushfires, insect and disease attack and so on In 1928, the Forests Commission undertook its first major aerial photography project over 15,000 acres of forest which is said to be the first of its kind in Australia. During the Second World War, large areas of Victoria were photographed by RAAF and used to produce orthophoto maps. By 1945 aerial photography of 13,000 square miles (3.4 M ha) was completed, including much of the inaccessible eastern forests. The Forests Commission started developing its own small format photography in the early 1970s. Simple, cheap and rapid methods of obtaining photographs using 70mm and 35mm cameras were developed Small pocket stereoscope to interprete aerial photographs in the field Adjustable lenses on foldaway wire legsSokkisha Tokyoforest measurement, surveying, forests commission victoria (fcv)

An increment borer is a specialised tool to extract a core sample of wood tissue from a living tree. The tool consists of a handle, an auger bit and a small, half circular metal tray (the core extractor) that fits inside the auger bit. The core sample can be used to count the rings, to reveal the age of the tree and its growth rate.Increment borer. The central core is stuck.

Foresters usually measure the diameter of trees at Breast Height – traditionally 4 foot, 6 inches – now 1.3 m – which is termed Diameter Breast Height Over Bark (DBHOB). Basal Area is the cross section of the tree trunk at breast height, and the sum for the stand or group of trees is expressed square feet per acre (after 1973 it was expressed in square metres per hectare). Lots of skinny trees, or a few fat ones, can have the same Basal Area, but when combined with the number of stems, Basal Area is a good indicator of stand density. Two common methods are used to measure of Basal Area – fixed area plots and angle count sampling. 1. Fixed area plots require setting out a small area, commonly 50 m x 20 m, and measuring all the trees at breast height, and doing some quick sums. 2. Angle count sampling involves a simple sweep of the forest from a fixed sampling point using a relascope, dendrometer sight, angle gauge, or glass wedge prism. This wooden builders ruler has been shaped at one end to create a shallow angle (usually less than 3 degrees). Standing in one spot, a sweep is made with the wedge held to the eye, and trees are counted as either “in” or “out”. The number of trees is multiplied by conversion factor of the wedge (10 in this case) to estimate basal area. It’s very quick and effective.Basal Area Angle Gauge The two ends fold up and one end (on the right) has been reduced in width to create a shallow angle for the viewer Home made by cutting down a wooden builder's ruler Many forestry students made their own Basal Area Angle Gauges and its thought this may be oneforest measurement, forests commission victoria (fcv)
