Although it may look like a pile of old springs, it is in fact a measuring device known as a Gunter Chain. The Gunter chain was invented by Rev. Edmund Gunter, Professor of Astronomy at Gresham College, London. A farmer would use a Gunter Chain to measure his fields, calculate the areas and thus the yield per acre of crops. The chain measures, perhaps not surprisingly, one chain or 22 yards, the length of a cricket pitch. The little brass tags indicate the 10 links that make up the chain. 10 chains by 10 chains equals one acre. 80 chains in length equal one mile.
This chain was given to the windmill by Steve Tallis of Ullesthorpe who used to run a farm in Frolesworth. Steve said that the chain belonged to his father, or even his grandfather. Judging by the design of the tags and handles the chain is probably about 100 years old.
William Jayes, longest-serving miller at Ullesthorpe from about 1834 to about 1855 (and possibly later), rented fields and gardens off Manor Road. On the tithe map of 1840 (LRO) these measured 6 acres, one rod, one pole. He paid approximately six shillings an acre per annum to the vicar of Claybrooke who owned the land.
