A repurposed Seandar diary for 1925 measuring 9.5 cm x 15 cm recording an 8 day tour of windmills, most of which located in Cambridgeshire. Planning notes for the trip list mills to be visited each day (as well as recommended inns in which to dine/stay).
Notes are made for the mills listed in 'Place access points' below, occasionally accompanied with dimensions and drawings. Mills which have been demolished are also recorded. A list of those mills not visited is given at the back.
Unindexed mills visited include Polton Mill, Shepreth End post mill, a tower mill at Bradley and the remains of tower mills at Chesterton, Boxworth and March.
Mills at Histon, Waterbeach, Yelling, Fen Drayton, Somersham, Warboys, Susards Farm, Madingley and St John's Highway are marked 'non-est'.
