This is held into position with a pivot that fits into a central hole in the bottom. The upper stone also has a deep horizontal socket in its steep side in which to place the wooden peg used as a handle to rotate or oscillate the upper stone. This is the earliest type of rotary quern in Britain. Rotary querns are where the grinding action is circular. Cropmarks Cropmarks are formed when the underlying moisture levels varies which effects the growth of agricultural produce (Ref. 1). This can be from an increase in moisture levels, from a negative feature such as a ditch or pit which produces a richer crop, or a reduced moisture level, from a positive feature such as a wall which results in a poorer yield. The best response for cropmarks is between June and July each year. This is however subject to many factors and the absence of cropmarks many not indicate the absence of archaeological features (Ref. 1). Datum Datum is an ordnance survey term for sea level. Domesday Book The Domesday Book is a manuscript record of the ‘Great Survey’ which was conducted in most of England and Wales and commissioned by William the Conqueror. The first draft was complete in August 1086 and written in Medieval Latin. Its original purpose was to establish what taxes had been owed during the reign of King Edward the Confessor, this helped William to reassert the right of the Crown and assess where the power lay in the land. The book contains the records of 13,418 settlements. Geld The Domesday Book records the tax, or geld unit, to the King or Lord. Geophysical survey Technology such as fluxgate gradiometer (for magnetometry) and resistance meter (for resistivity) are
