The plots on Lightpill Allotments are measured out in ‘lugs’. The standard measurement for allotments is ‘rods’ or ‘poles’, both equating to 30.25 square yards.
The term ‘lug’ is an even older one and, so far, I have been unable to find any definitive information about it but a Heritage Centre I spoke to said that a ‘lug’ was about 40 square metres.
Further confusion, another old text (here) states that a ‘lug’ is a linear length, not a measure of area, equivalent to just over 5 metres.
However, if anyone can point me in the direction of the definitive answer then please contact me (john@southmillhouse) and in the meantime I shall start enquiries as to whether we can move to metric sizes, as recommended by the National Allotment Society.
