The measure was probably for CD’s research on the formation of vegetable mould by earthworms, which involved calculating the amount of earth brought up by worms from beneath the surface over a given time. Worm castings were collected from two separate square yards near Leith Hill Place in Surrey by CD’s niece Lucy Wedgwood between October 1870 and October 1871 (see Earthworms, pp. 167–8). See also letter from Lucy Wedgwood, 20 November [1871].
