The Justiciar was the head of all legal matters and he or the Conquerer's wife represented the King at the Royal Court in his absence from the realm. The chamberlain was a financial officer of the household; his work was rather that of auditor or accountant. The Chancellor headed the Chancery and the chapel. Other household offices were steward, butler, constable, and marshall. The Treasurer was responsible for the collection and distribution of revenue and was the keeper of the royal treasure at the palace at Winchester. He was also an important member of the household and sat in the Exchequer at Westminster, where he received the accounts of the sheriffs. The Exchequer was composed of the Justiciar as head, the chancellor, the constable, two chamberlains, the marshall and other experienced councilors. The word "Exchequer" came from the chequered cloth on the table used to calculate in Roman numerals the amount due and the amount paid. The word "calculate" derives from the word "calculi", meaning pebbles. It was a kind of abacus. The Exchequer received yearly from the sheriffs of the counties taxes, fines, treasure trove, goods from wrecks, deodands, and movable property of felons, of persons executed, of fugitives, and of outlaws due to the Crown. The Conqueror presided yearly over feasts involving several thousand guests at Westminster Hall, which was 250 feet by 70 feet with a high ceiling, the largest hall in England.
The Conquerer's reign was a time of tentative expedients and simple solutions. He administered by issuing writs with commands or prohibitions. These were read aloud by the sheriffs in the county courts and other locations. Administration was by the personal servants of his royal household, such as the chancellor, chamberlain, constable, marshals, steward, and butler. The language of government changed to Latin. The chancellor was from the clergy and supervised the writers and clerks, who were literate, and appended the great seal before witnesses to documents. He also headed the staff of the royal chapel. The chamberlain was a financial officer who audited and accounted. The constable was responsible for supplies for the knights of the royal household. He also supervised the care of horses, hounds, hawks, and huntsmen, houndsmen, and foresters. The marshals came from less important families than the constable and they preserved order in the king's hall and recorded expenditures of the household officers on tallies. The steward was a great baron whose duties were chiefly ceremonial, such as placing the dishes before the king at banquets.
Sheriffs, who had first been head of shires, became powerful figures as the primary agents for enforcing royal edicts. There was no longer supervision of them by earls nor influence on them by bishops. They were customarily prominent barons. They collected the royal taxes, executed royal justice, and presided over and controlled the hundred and county courts. They were responsible for remitting a certain sum annually. If a sheriff received more than necessary, he retained the difference as his lawful profit of office. If he received less than necessary, he had to make up the difference from his own pocket. Before rendering this account, he paid the royal benefactions to religious houses, provided for the maintenance of stock on crown lands, paid for the costs of provisions supplied to the court, and paid for traveling expenses of the king and his visitors. The payments were initially paid in kind: e.g. grain, cattle, horses, hounds, and hawks. Sheriffs also took part in the keeping of castles and often managed the estates of the King. Most royal writs were addressed to the sheriff and county courts. They also led the county militia in time of war or rebellion. At times, a sheriff usurped royal rights, used royal estates for his own purposes, encroached on private land and rights, extorted money, and collected revenues only for his own pockets. Over the centuries, there was much competition for the authority to select the sheriff, e.g. by the king, the county court, the barons, and the Exchequer. There was also much pressure to limit his term to one year. Over time, the powers of the sheriffs slowly declined.
Royal income came from customary dues, profits of coinage and of justice, and revenues from the King's own estates. For war, there was no change in the custom that a man with five hides of land was required to furnish one heavy armed horseman for forty days service in a year. The fyrd was retained. A threat of a Viking invasion caused the Conquerer to reinstate the danegeld tax at 6s. per hide, which was three times its old rate. (The price of an ox was still about 30d.) To impose this tax uniformly, he sent commissioners to conduct surveys by sworn verdicts of appointed groups of local men. A detailed survey of land holdings and the productive worth of each was made in 1086. The English called it the "Doomsday Book" because there was no appeal from it.
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 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 bondmen. There are 50 villeins and 12 bordars with 20 ploughs. The mill there pay The survey shows a few manors and monasteries owned a salthouse or saltpit in the local saltworks, from which they were entitled to obtain salt. In total there were about 110,000 villani [former coerls regarded as customary, irremovable cultivator tenants]; 82,000 bordarii; 7,000 cotarii and cotseti [held land by service of labor or rent paid in produce], and 25,000 servi [landless laborers]. There are no more theows. This survey resulted in the first national tax system of about 6s. per hide of land. 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."
