Description: | makers mark, engraving, Cail Newcastle upon Tyne
It is the surveyor's job to measure the location of a pit and to determine where shafts, buildings and underground workings should be placed. One of his tools is a level, which is set up with great precision using a spirit level. With this instrument the surveyor can measure differences in height very accurately. This level was made in the 1800s by Cail, a Newcastle instrument maker. | Source: | Tyne & Wear Archives & Museums | Identifier: | emu.ecatalogue.science&industry.481231 | Go to resource |
