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)

Disston Saw Works of Philadelphia was one of the better known and highly regarded manufacturers of handsaws in the United States. During the Machine Age, the company was known as Henry Disston & Sons, Inc. a supplier of industrial saw blades. History: The story of handsaws in the United States mirrors the technical and development of steel in Sheffield, England, which was the center of handsaw production during the 18th century and through most of the 19th century. England's political and economic lock-on steel making in the colonies held American saw makers at bay until well after the Revolutionary War. American steel producers were unable to compete until the US government introduced import tariffs to level the playing field in 1861. Henry Disston: Henry Disston (1819–1878) began his career as an American saw maker in Philadelphia. He had emigrated from England in 1833 and started making saws and squares in 1840. In 1850, he founded the company that would become the largest saw maker in the world, the Keystone Saw Works. Some five years later, Disston built a furnace—perhaps the first melting plant for steel in America and began producing the first crucible saw steel ever made in the United States. While his competitors were buying good steel from Britain, he was making his own, to his specification, for his own needs. Disston subsequently constructed a special rolling mill exclusively for saw blades. Over the following decade, the Disston company continued to grow, even while dedicating itself to the Union Army's war effort. In 1865, when his son Hamilton Disston rejoined the business after serving in the Civil War, Disston changed the company's name to Henry Disston & Son. Henry Disston and his sons began to set the standards for American saw makers, both in terms of producing high-quality saws and files in 1865 through his development of innovative manufacturing techniques. In September 1872, Henry Disston and two other men dug a part of the foundation for what was to become the largest saw manufacturing facility in the world: Disston Saw Works. This was in the Tacony section of Philadelphia. Having previously moved his expanding business from near Second and Market Streets to Front and Laurel Streets. It took over 25 years to move the entire facility to Tacony. Henry Disston was renowned for having one of the first industries that exhibited environmental responsibility, as well as a paternalistic view towards his employees. For example, he had thousands of homes built in Tacony for his workmen. Funds to purchase these homes were made available through a building and loan association set up by the Disston firm. His caring influence on the community was evident in everyday life. To meet employees' cultural needs, a hall and a library were built with Henry Disston agreeing to pay a fixed sum towards its maintenance. The Tacony Music Hall was erected in 1885, also with the assistance of Disston money. Henry Disston had fallen ill by 1877 and never truly recovered; he suffered a stroke and died the next year. This came only one and a half years after seeing his products receive the highest honors at the great Philadelphia Centennial Exposition of 1876. His vision of a working-class community and the completion of the transfer of his enormous saw plant was carried out by his wife and his sons. The company, by the early 20th century, cast the first crucible steel in the nation from an electric furnace in 1906. The firm's armor-plate building near Princeton Avenue and Milnor Street contributed tremendously to the World War II effort. But the company's innovation and industriousness would not last forever. In 1955, with mounting cash-flow problems and waning interest on the family's part to run the firm, Henry Disston and Sons were sold to the H.K. Porter Company of Pittsburgh. Porter's Disston Division was sold in 1978 and became the Henry Disston Division of Sandvik Saw of Sweden. This division was then sold in 1984 to R.A.F. Industries of Philadelphia and became known as Disston Precision Incorporated, a maker of specialized flat steel products. In 2013, R.A.F. Industries sold Disston Precision Inc. in a private sale. Although the company has ceased making Disston handsaws, the Disston brand name still exists in this firm.

The firm Dring and Fage were active from 1790 to 1940 in London and were manufacturers of hydrometers and mathematical instruments they became established in London in 1790 by John Dring, who was a brass worker and hydrometer maker, and William Fage. Dring and Fage manufactured also saccharometers and other instruments used to measure the strength of alcohol. These instruments were primarily used to calculate excises. They traded at various addresses in London and they were at 56 Stamford St. between 1903 and 1938. By 1850 the company was owned by Edward Hall and Edward Jenkin and in 1940 the company became Dring & Fage Ltd, trading till the 1960s. Historically, gauging has meant measuring a volume, these gauging instruments were used by Customs and Excise and manufacturers for determining the volume and contents of liquid containers. For Customs the determination and collection of duty on imported goods which has had a very long history. Chaucer was a Customs Officer as was his father and grandfather, excise was first officially introduced in 1643, with the aim of maintaining military forces raised by the English Parliament at that time. Excise was initially a duty on home produced alcoholic beverages and soap but being easily applied, spread rapidly to a wide range of goods including imports of varying kinds. The government departments of Customs and Excise merged only in 1909 and it is from around this time that our instrument was made and used. The item demonstrates a long social history of the practice of Government's collecting duty on alcoholic beverages and thereby makes this item historically significant as it was used locally at Port Fairy by the ports Customs agents.

Marking Gauge. Manufactured by Marples of Sheffield, England. Also known as a scratch gauge, it is used in woodworking and metalworking to mark out lines for cutting or other operations. The purpose of the gauge is to scribe a line parallel to a reference edge or surface. The gauge consists of a beam, a headstock, and a scribing or marking implement, typically a pin, knife, pen or wheel. The headstock slides along the beam, and is locked in place by various means: a locking screw, cam lever, or a wedge.Maker's namemarking gauge, measuring tools, marples of sheffield

In the earliest years of the Colac-Beech Forest-Crowes line all trains were hauled by NA-class 2-6-2 tank locomotives. From 1926, with the introduction of articulated Beyer Garrett locomotive G41, it hauled the majority of trains with the NAs providing supplementary service as required. Late in 1945 Garratt G41 was again out of action undergoing repairs at the depot in Colac so regular traffic again was handled by an NA for a short time. The line continued to survive on pulpwood long after other VR narrow gauge lines had ceased operation but finally, on 30 June 1962, a dilapidated G42 hauled the last train of goods wagons and vans to Beech Forest and return.Focus on Victoria's Narrow Gauge: Beech Forest Line, Part One.

This mortice marking gauge has an adjustable sliding arm. The gauge is used for scribing two lines on a flat surface such as timber for measuring and cutting. It is a hand-powered tool that would have been used by a tradesperson such as a cabinet maker, woodworker or carpenter. The hand tool shows signs of much use. The ‘W. Maples & Sons, Hibernia’s catalogue of 1867 had a very similar tool, called a Mortice Gauge, column 2, page 15. W. MARPLES & SONS- William Marples Snr. had a business on the Sheffield Moor in 1773/74. In 1821 his son William Jnr. At 12 years old began in his father’s joinery business. 1833 the firm was known as a tool manufacturer. In 1838 Marples called his business Hibernian Works and moved to 67-69 Spring Lane, Sheffield. When he moved to Westfield Terrace in 1856, he called his business Hibernia Works (no ‘n’ on the end). The business remained at this address for 116 years. In about 1859 the firm began using the Lyre (Irish harp) mark. In 1860 or so the two brothers, Edwin and William Marples, became partners and the firm became William Marples and Sons. The firm introduced the single shamrock symbol in 1860-61. The boys’ brother Albert joins the firm in 1863. In 1875 the company registered both the name ‘Hibernia’ and the trade mark symbol of a Triple Shamrock and the use of these trademarks continued for many decades, into the 1940 and the firm, with many changes, was still in business in the early 21st century. About Shamrock and Hibernia, both are related to Ireland and W.

The Australian Customs Service, Melbourne, donated a set of gauging instruments, and Port Fairy Customs donated another instrument, the Sike’s Hydrometer, to Flagstaff Hill Maritime Village, all of which were no longer required. However these ullaging tools were in use for many years by Customs officials, called Gaugers. Ullaging is a term describing the measurement of the amount of liquid remaining in a container of spirits such as a cask or barrel. It can also measure the free space or head space remaining. The primary role of customs officers in Victoria was to calculate the tariff or excise duty payable on goods imported into Victoria. (Excise duty is a tax on goods produced within a country, and customs duty is imposed on imports.) Customs officers spent a great deal of their time measuring and weighing goods, and then calculating the amount of duty to be paid by the importer. The tariffs for different products varied, and officers consulted published lists. Calculating the duty payable on a barrel of brandy was a detailed task. The gauger had to measure the barrel to determine its volume. Barrels were irregular in shape, and finding the volume required several measurements and checking tables of figures. Alcoholic content was then measured with a hydrometer. The duty paid varied according to the alcoholic strength of the spirits. Uniform national customs and excise duties were operative in Australia from October 1901. These tools were still being used in Australia in the 1950’s. The Federal Government still imposes excise taxes on goods such as cigarettes, petrol, and alcohol. The rates imposed may change in February and August each year in response to changes in the consumer price index. ULLAGING TOOLS (1) Head Rod - this instrument measures the diameter of the heads (top and bottom ends) of a cask or barrel. The shaped brass pieces on the head rod enable the diameter of a barrel to be measured inside the chimes at the head end. The slide rule could then be used to calculate the internal volume of the barrel. On the reverse side is a set of ullaging scales, used like those on any ullaging rule, to calculate the volume of liquid in a partially filled barrel. (2) Bung Rod – this instrument measures the diameter of a cask or barrel when it is lying on its side. It is a rod that fits into the ‘bung’ hole of a cask and is long enough be extended to reach the opposite side of the cask. The brass sliding pointer can be moved to mark the ‘wet’ line. When the rod is removed the bung measurement can be read from the scale on the rod. (3) Long Calipers - this instrument measures the length of the cask between the heads. It has two rules sliding beside each other, each end having another piece of wood fixed firmly at right angles downwards then turned inwards at the ends so as to reach over the heads of the casks without touching the projecting ends. The centre pieces enable it to extend or contract, changing the distance between the two other parallel sides, the distance they are apart being shown by the rule on the sliding pieces. (4) Cross Calipers – this instrument is used to take the bung diameters of casks, or "the Cross " as it is called. This instrument has two rules sliding beside each other, each end having another piece of wood fixed firmly at right angles downwards, together forming a 3 sides of a rectangle with the centre pieces enabling it to extended or contracted, changing the distance between the two other parallel sides, the distance they are apart being shown by a the rule on the sliding pieces. (5) Sike’s Hydrometer – this instrument is used to gauge the strength of different alcoholic spirits when fitted with the different weights in the set. Every set is individually calibrated to ensure that it meets the exact Standard Weight and Measure compliance, then every piece in that set is stamped with the same number by the Calibrator, to ensure that the measurements are taken using the same hydrometer set.
