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.

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.
