Gunter type surveying chain, 100 links (66 feet), by Charles Baker, 244 High Holborn, London, England, 1857-1865
Surveyor's chain made by Baker in the mid 19th century. Ropes, chains, tapes and rods have all been used for measuring distances. In about 1620, English mathematician and astronomer Edmund Gunter (1581-1626) developed this type of metal chain for determining the area of plots of land. The chain is 20 metres (66 feet) long, and is made of 100 links. Markers are placed at regular intervals.
