A Gunter’s Chain, an old land surveying instrument, is named after its inventor, Edmund Gunter (1581-1626), an English mathematician and astronomer. It was first produced in 1620. The tool has 100 links and is 66 feet or one chain long. The links are marked off in groups of ten by metal tags or rings. A quarter chain (25 links) is called a rod or pole and ten chains make a furlong and 80 chains a mile. The traditional cricket pitch is 22 yards or one chain long. This chain is said to have been used by Gilbert Nicol when the Warrnambool to Hamilton Road was constructed in the 19th century. Gilbert Nicol was an early settler in Warrnambool who, with John Craig, established the first hotel (and the first building) in Warrnambool in 1847. Nicol later owned the property ‘Rosehill’ in the Warrnambool area. As the chain was given to the Warrnambool and District Historical Society by the Town Clerk, Keith Arnel, it is likely that the chain was one of the items in the old Warrnambool MuseumThis Gunter’s Chain is of importance because it is an early land measuring device that was used for over 250 years and has great historical and mathematical significance. If it is correct that it was used by Gilbert Nicol when the Warrnambool to Hamilton Road was built then it has considerable local significance and dates back to the 19th century. This is a metal tool which consists of 100 metal pieces or links joined together by loops at each end with two metal loops in between each link. The links joined together form a chain. The two ends of the chain have small metal handles attached. At intervals along the chain there are additional rings or metal pieces attached. The metal is very rusted.gunter’s chain, land measurement tools, history of warrnambool

Gunter's chain (also known as Gunter’s measurement) is a distance measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. The provenance of this particular Gunter Chain is unknown but it is believed to be used either by the City of Bendigo / Sandhurst or the Lands Department locally when measuring and laying out plots and streets locally. A 66-foot (20.1 m) chain divided into 100 links, marked off into groups of 10 by brass rings or tags. Each link is 7.92 inches (201 mm) long. A quarter chain, or 25 links, measures 16 feet 6 inches (5.03 m) also called a a rod (or pole) measure. Ten chains measure a furlong and 80 chains measure a statute mile. city of greater bendigo surveying

Before metrication was introduced into Australia in the 1970s land was measured in chains and links. Many old parish plans show length measurements in chains and links. Area was shown in acres, roods and perches. Gunter's chain was used for measuring distance in surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). Gunter developed the measuring chain of 100 links. The chain and the link, became statutory measures in England and subsequently the British Empire. After metrication units of length were measured in meters and area in hectares. The chain was later superseded by steel ribbon tape.The 66-foot long (1 chain) Gunter's Chain was a fundamental instrument for land surveying. It is divided into 100 links (each 7.92 inches long) which are marked off into groups of 10 by brass tags with 'fingers' to indicate 10, 20, 30, 40 and 50 links from the hand grips, thus simplifying intermediate measurements. Each end of the chain is fitted with a brass hand grip. It was heavy and sturdy enough to be dragged through the bush and over rough terrain on surveying transects. Giving rise to the common forestry term "chainman" for the person tasked with dragging it. 1 chain = 100 links = 22 yards = 66 feet = 792 inches = 4 rods, poles or perches. 10 chains = 1 furlong 80 chains = 1 mile 1 acre = 10 square chains = 4 roods = 160 square rods, poles or perches.forest measurement, surveying, forests commission victoria (fcv)

A chain is a unit of length equal to 66 feet or 22 yards. This is a statute measure in the United Kingdom. One link is 100th part of a chain, which is 7.92 inches (20.1 cm). The chain and link became standard surveyors' units of length and crossed to the colonies from the United Kingdom. The chain is the unit of linear measurement for the survey of the public lands as prescribed by law. In Australia most building lots in the past were a quarter of an acre, measuring one chain by two and a half chains. Also street frontages, roads, laneways. The chain also survives as the length of a cricket pitch, being the distance between the stumps. Surveyors and residents of the Kiewa Valley used the Steel Band Surveyors Chain to measure distances when developing the land.Surveyors' steel band measuring tape, known as a 'standard band', or a 'steel band chain'.This chain consists of a long narrow strip of steel of uniform width of 3 mm and thickness of 0.3 to 0.6 mm. The chain itself is between 20 m and 30 m long.surveyors, surveyors chain, measurement of distance

This is a set of 1photographs of surveyors in the field measuring distances using chains, taking observations using theodolites and operating electric distance measurement equipment. They were probably employed in establishing mapping and geodetic control operations or the surveyors may have been in training. The photos were most likely taken in the 1950s and 1960s. Photos .1P to .6P feature personnel setting up geodetic survey chaining equipment to measure distances. The surveyor in Photo .5P is LTCOL Howard Angus Johnson MBE who served from 1936 to 1954. The RA Svy surveyor in photos .7P to .12P were using a theodolite to take angular measurements. They were usually supported by an observer who recording their readings on a booking form. The surveyor in Photo .10P and .11P is LTCOL Jorge Gruszka, who served from 1955 to 1985. He was CO of the Army Survey Regiment from 1982 to 1985. The surveyor in photo .13P is cutting an identification blaze on a tree using a hammer and chisel. The tellurometer in Photos .14P to .16P was a MRA1 microwave Electronic Distance Measuring instrument (EDM) introduced in 1958. It and later models were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. The surveyor with the slouch hat is Colonel James ‘Jim’ Leslie Stedman, who served from 1941 to 1978. He was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983.

Maize,has been grown on the Orbost flats for at least 70 years. When early settlers began to arrive on the Snowy River somewhere in the 1880s, the land was mostly swamps and heavily timbered jungle on the river frontages. The swamps were drained, bit by bit, by men with short handled shovels and working in mud and water. The frontages were cleared by axe and shovel and fire. Several kinds of crops were experimented with such as hops, hemp and maize, the latter grew particularly well and became the main crop of district. The problem then was to thresh and deliver the product to the market. A small single cob machine was brought here and one man turned the handle, while the boy or Mum fed the cobs singly into the machine. A good day’s work would thresh about 50 bushels or about 12 bags (4 bushels). The task then was to cart the maize to market. For a few years this was done by horses and dray carrying about 60 bushels to Mossiface, where it was loaded onto river boats to Lakes Entrance, and then by ocean boats to Melbourne. Later it was taken to Bairnsdale by foot and loaded onto the trains to Melbourne. (more information in Newsletter October 2006) This crib, measuring seven chains, sixteen feet, contained 10,000 bags of maize cobs which were grown by Linc Timmons on Peter Irvine's farm (Fairlea?) in Orbost, East Gippsland. The growing of maize in the Orbost district contributed significantly to the economy of the township for many years, The many maize cribs once seen on the surrounding farms have now disappeared and this photograph is a pictorial record of that significance.A black / white photograph of a large maize crib full of maize in a paddock.

At the base of the paddock on the northern side is a concrete winding engine foundation measuring 8 by 4 feet, and standing 2 feet high. The foundation has ¾-inch mounting bolts. Battery site 70 metres to the west of the mine site are the concrete foundations of a 10head battery. The foundations measure 16 by 11 feet, and stand 4 feet high. Part of the battery's loading ramp still survives, and on the eastern side of the battery foundations is a large concrete engine foundation. Near this engine foundation is a 3 foot square concrete pad, which still retains a circular impression. Presumably this was a stand for a gas producer cylinder. Located between the battery and the mine site is a rubbish dump which contains sections of an iron stack, and perhaps the remains of the gas producer cylinder.

Textiles. Large pieces of linen, 119 cm x 96 cm edged with a border, 8.5 cm deep of cotton lace, matching the lace of the bedspread. This lace has a corded effect, outlining 'finger shapes' of floral pattern, alternating with an open chain stitch, looped effect. Like the bedspread, the pillowcase is embroidered with the initials in satin stitch and some cut work embroidery. A smaller rectangle of linen fabric is stitched to the back of the fabric, to hold a pillow in place. Measuring 81 cm. x 48 cm. This envelope is tied with three ties of cotton tape. It could be presumed that these pillow slips would be a decorative feature of the bed linen.

Before metric measurement was introduced land was measured by a tool of chains and links called a surveyor's chain. The first surveyor's chain was designed by the English clergyman and mathematician Edmund Gunter (1581-1626) and introduced in 1620. It comprised of a metal chain made up of 100 links measuring a precise overall length of 66 ft or 22 yards, with each link measuring 7.92 inches (201.168 mm). The Gunter's chain was originally intended to be used in the accurate laying out and measurement of plots of land, for legal and commercial purposes, but was subsequently widely used by surveyors throughout the British Empire and Europe, with an Imperial mile being 80 times the Gunter's chain length. A tool used to survey the land before the introduction of the metric system.Surveyor chain Gunter type, 100 links measuring 66 feet in length. Hand grips at each end of chain. Wire links are approximately eight inches long. Incised tags or markers are attached to each tenth link of chain to assist with the more accurate recording of intermediate distances.surveying tool

A fob watch is an instrument for measuring time. It is designed to hang from a chain that is attached to a wearer's waistband or waistcoat. The chain keeps the fob watch from being dropped or falling out of a pocket. A person possessing a fob watch or similar instrument in the 18th century would be viewed as someone in a good financial position and often a position of power or respect. It was a social statement as well as a useful object.Silver pocket watch and brass iron winder. Watch has Roman numerals on face and gold flower, floral and diamond shaped motif.

Thomas Walker & Son was internationally renowned in the manufacturing of ships logs. Founding father Thomas Walker (1805–1871), an engineer in Birmingham, patented a mechanical log in 1878 which was a recording instrument that attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. Thomas Walker first went into business to manufacture stoves at 58 Oxford Street Birmingham. Walker’s self-feeding stove was widely lauded at the Paris Exhibition of 1855, winning a prize medal and kick starting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ships log model invented by his Uncle that Thomas Walker became interested in the further development of this device, used to ascertain a ship’s speed. Walker continued to improve on the common log for the company of Massey & Sons and these improvements were deemed revolutionary. This log became a firm favourite of the West India Association (British-based organisation promoting ties and trade with the British Caribbean) and the most common log in use for two generations. It took till 1861 for Thomas Walker and his son, Thomas Ferdinand Walker (1831-1921) to patent the first Walker log of many. Together, with the introduction of the A1 Harpoon Log two years later, they established the Walker Log Business as a force to be reckoned with. By the time of his passing in 1871, Thomas Walker Snr had not only founded a family business with considerable staying power but also instilled a tradition of public service. Having sat as a representative on the Birmingham Town Council for 15 years and played an active role in public works, he was soon given the nickname of ‘Blue Brick Walker’. Much like his father, Thomas Ferdinand Walker changed the face of the maritime industry. His patent of 1897, the ‘Cherub’ log, was a notable departure from the past providing a far more accurate reading and replacing the majority of logs of the age. They were the first to produce an electric log and the Walker factory was one of the first to introduce the 48 hour work week for employees. This ship log was invented and made by a significant marine instrument maker and innovator of machinery. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades. Ship Log, three analogue dials calibrated in increments of Miles, the Rocket Log is a nautical instrument for measuring a vessel’s speed and distance traveled. The floating log was drawn behind the ship over a fixed time period in order to measure the distance traveled. The counter could measure enough miles to cover the maximum distance traveled by a ship in one day. The log has two distinct parts; a brass register, made by Walker, showing the distance recorded and the rotator made by Reynolds, that spins in the water driving the counter. both parts are connected by a linked chain. The register has a cylindrical brass body approx 4.5 cm diameter containing registering mechanism with hardened steel bearings. Distance is indicated by the three pointers on enamel plate as follows: graduated every 10 miles from 0-100; every mile from 1-10; every 1/4 mile from 1/4 -1. A brass sling and eye secured to the body enables it to be attached to the taffrail.
