not set down in his writ. And all the recorded particulars were afterwards brought to him. The list of questions asked of the jurors was recorded in the Inquisitio Eliensis. The contents of Domesday Book and the allied records mentioned above. The primary purpose of the survey was to ascertain and record the fiscal rights of the king. These were mainly: the national land-tax (geldum), paid on a fixed assessment, certain miscellaneous dues, and the proceeds of the crown lands. After a great political convulsion such as the Norman Conquest, and the following wholesale confiscation of landed estates, William needed to reassert that the rights of the Crown, which he claimed to have inherited, had not suffered in the process. His Norman followers tended to evade the liabilities of their English predecessors. The successful trial of Odo de Bayeux at Penenden Heath near Maidstone in Kent less than a decade after the conquest was one example of the Crown's growing discontent at the Norman land-grab of the years following the invasion. Historians believe the survey was to aid William in establishing certainty and a definitive reference point as to property holdings across the nation, in case such evidence was needed in disputes over Crown ownership. The Domesday survey, therefore, recorded the names of the new holders of lands and the assessments on which their tax was to be paid. But it did more than this; by the king's instructions, it endeavoured to make a national valuation list, estimating the annual value of all the land in the country, (1) at the time of Edward the Confessor's death, (2) when the new owners received it, (3) at the time of the survey, and further, it reckoned, by command, the potential value as well. It is evident that William desired to know the financial resources of his kingdom, and it is probable that he wished to compare them with the existing assessment, which was one of considerable antiquity, though there are traces that it had been occasionally modified. The great bulk of Domesday Book is devoted to the somewhat arid details of the assessment and valuation of rural estates, which were as yet the only important source of national wealth. After stating the assessment of the manor, the record sets forth the amount of arable land, and the number of plough teams (each reckoned at eight oxen) available for working it, with
