- History Of Use
- Used in Quebec and BC - including the Skeena Region. This is a common surveying instrument. There were only two kinds of levels availabe when the railway cam, to be used in surveying. These were the "Y"level and the dumpy. The level was made by E.R. Watts & Sons, London, England. The level was bought by mother-for-father in 1935 for $25 used. It was 30 years ol then. The previous owner was Polyblank - a railway surveyor. Thomas Edward Clarke was born in Bothwell, Ont. in 1888, came west in 1908. In Edmonton he was hired as Chainman for Garnet Hughts on preliminary location of GTP to Jasper; reached Jasper Christmas 1908. Then he continued surveying until 1960 in different areas of BC In 1926 he was the Assistant District Engineer for Dept. of Public Works in Smithers. The Central Park building was 6 yrs. old then and he had an office on the second floor. The position he had was equivalent to the current position of "Highways Superintendant". (In 1926 conversion had just been made from Horse and wagon to trucks.)He was involved with initial road building in the province.
