The survey revealed, for instance, that one estate had "on the home farm five plough teams: there are also 25 villeins and 6 cotters with 14 teams among them. There is a mill worth 2s. a year and one fishery, a church and four acres of meadow, wood for 150 pigs and two stone quarries, each worth 2s. a year, and two nests of hawks in the wood and 10 slaves." This estate was deemed to be worth 480s. a year. Laxton "had 2 carucates of land [assessed] to the geld. [There is] land for 6 ploughs. There Walter, a man of [the lord] Geoffrey Alselin's has 1 plough and 22 villeins and 7 bordars [a bordar had a cottage and a small amount land in return for supplying small provisions to his lord] having 5 ploughs and 5 serfs and 1 female serf and 40 acres of meadow. Wood [land] for pannage [foraging by pigs] 1 league in length and half a league in breadth. In King Edward's time it was worth 9 pounds; now [it is worth] 6 pounds." Ilbert de Laci has now this land, where he has twelve ploughs in the demesne; and forty-eight villani, and twelve bordars with fifteen ploughs, and three churches and three priests, and three mills of ten shillings. Wood pastures two miles long, and one broad. The whole manor five miles long and two broad. Value in King Edward's time sixteen pounds, the same now. That manor of the town of Coventry which was individually held was that of the Countess of Coventry, who was the wife of the earl of Mercia. "The Countess held in Coventry. There are 5 hides. The arable land employs 20 ploughs. In the demesne lands there are 3 ploughs and 7 ploughs. In the demesne lands there are 3 ploughs and 7 bondmen. There are 50 villeins and 12 bordars with 20 ploughs. The mill there pay[s] 3 shillings. The woodlands are 2 miles long and the same broad. In King Edward's time and afterwards, it was worth 22 pounds [440 s.], now only 11 pounds by weight. These lands of the Countess Godiva Nicholas holds to farm of the King." The survey shows a few manors and monasteries owned a salt-house or salt-pit in the local saltworks, from which they were entitled to obtain salt. This survey resulted in the first national tax system of about 6s. per hide of land. The survey also provided William with a summary of customs of areas. For instance, in Oxfordshire, "Anyone breaking the King's peace given under his hand and seal to the extent of committing homicide shall be at the King's mercy in respect of his life and members. That is if he be captured. And if he cannot be captured, he shall be considered as an outlaw, and anyone who kills him shall have all his possessions. The King shall take the possessions of any stranger who has elected to live in Oxford and who dies in possession of a house in that town, and without any kinfolk. The King shall be entitled to the body and the possessions of any man who kills another within his own court or house excepting always the dower of his wife, if he has a wife who has received dower.
