Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

A Storm Glass and Thermometer such as this one would be used in predicting or forecasting the weather. Farmers used predictions they read from their Storm Glass to prepare for stormy weather or for choosing a good time for planting or harvesting their crops. This could mean to them the difference between a good year and a year without income. This design has been in use since the early 1800’s. According to Admiral Fitzroy (who studied the storm glass and wrote instructions on its use) the liquid in the glass changes composition and appearance according to the direction of the air moving around it. He advised the user to disturb the contents once or twice a year by tipping it upside down and shaking it gently. Item is a good example of a barometer/thermometer that would have been in most homes and farms from the late 19th century and early 20th century. This item would have been massed produced at the time therefore easily available and quite cheap to purchase making this particular item not very significant as not associated with a historic person or property or with a known manufacturer or date.Storm Glass and Thermometer, commonly called a 'Cottage Barometer', mounted on a rectangular dark rectangle of wood, top corners rounded. The Storm Glass (or weather glass, or chemical weather glass) is suspended in a long oval shaped hole in the wood on left side, held in place at top and at bottom with 2 metal bands secured by nails. The glass of this gauge is hand blown, sealed at the top with another layer of glass. The watery fluid in the storm glass is opaque brownish colour with dark particles floating in it. (Storm glasses were usually filled with a variation of a mix of camphor, distilled water, ethyl alcohol and silver nitrate.) The alcohol thermometer is mounted on the right side of the wood, bulb resting in a hollow, attached at top and near base by 2 thin metal strips, with clover-leaf shaped ends, nailed into place. Over the bulb is nailed a metal guard with 3 ventilation slits cut into it. On left of thermometer is a scale, stamped into wood, 30 below zero to 130 above zero, in 2 degree intervals. A border of 2 thin parallel lines, with remnants of light coloured paint, is around the block of wood. On the reverse side, a metal plate is nailed to the top with a mounting hole in it. Impressed sideways along edge of barometer is "STORMY" "CHANGE" "FAIR". Across the top of the thermometer is a fleur de leis in the wood, and above this it is stamped "FAHRENHEIT". On right of the thermometer, stamped into the wood, is "BLOOD/HEAT", "SUMR/HEAT", "TEMPE/RATE", "FREEZ/ING". On the back of the wood, at the base, are remnants of a white sticker with "...111.73". Carved into the wood is "HOLLAND / AV". flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, barometer, cottage barometer, storm glass, thermometer, chemical weather glass
