It was built on the site in 1839 by a convict artisan from Launceston. The Royal Engineers Office in Launceston prepared plans for a more substantial stone and brick dwelling. The original quarters at the Mount Direction station had been built of timber by the late 1830s they were rundown. In the 1830s semaphore signals were added to the flag system and in 1835 the system became two-way. Originally, a system of flags was used, rather than the traditional semaphore system mentioned above. These 6 stations covered a total distance of 60 kilometres. Stations were established at Low Head, George Town, Mt George, Mount Direction, Windmill Hill and the Port Office. The Tamar Valley signal system was first introduced in 1825. To increase the speed of communication, a signal system was required to travel between Low Head at the mouth of the Tamar River to the Port Office in Launceston. However, the system was limited by bad weather and could not be used at night, despite attempts to do so by putting lamps on the arms.Įarly European roads in north-east Tasmania were in poor condition and transport was mainly by ship along the Tamar River. After much success, the semaphore system was implemented by almost every European state.īy the time the technology entered colonial Australia, the average speed of transmission was about two words per minute. The system was adopted by other countries, including Britain, Sweden and Spain. Over 550 stations were set up covering France and enabling military and national communication to travel further, faster. Each arm had seven positions and the cross arm had four this meant that the system had a 196-combination code to be used in communication. The system involved a tower with two arms on a mast connected by a cross-arm. In the 1830s semaphore signals were added to the flag system and in 1835 the system became two-way.įrench engineer Claude Chappe was the first person to create an 'optical telegraph' or semaphore system in 1792. These 6 stations covered a total distance of 60km, and were initially based on a flag signalling system. Stations were established at Low Head, George Town, Mount George, Mount Direction, Windmill Hill and the Port Office. A signal system was required to assist travel between Low Head at the mouth of the Tamar River to the Port Office in Launceston. The rough conditions of the early European roads in north-east Tasmania meant than transport was mainly by ship along the Tamar River. Used by early surveyors compiling a trigonometric survey of Tasmania, see if you can find the stone cairn, quarries and postholes. Tamar Valley semaphore system Cast iron gates and a dry stone wall mark the time of the pastoral lessees, and you may find the eye bolts used to stabilise the original semaphore mast.
