The center of government was a collection of tenants-in-chief, whose feudal duty included attendance when summoned, and certain selected household servants of the King. The Exchequer became a separate body. The payments in kind, such as grain or manual services, from the royal demesnes had been turned into money payments. The great barons made their payments directly to the Exchequer. The income from royal estates was received by the Exchequer and then commingled with the other funds. Each payment was indicated by notches on a stick, which was then split so that the payer and the receiver each had a half showing the notches. The Exchequer was the great school for training statesmen, justices, and bishops. The Chancellor managed the domestic matters of the Crown's castles and lands. The great offices of state were sold for thousands of pounds, which caused their holders to be on their best behavior for fear of losing their money by being discharged from office. One chancellor paid Henry about 3000 pounds for the office. Henry brought sheriffs under his strict control, free from influence by the barons. He maintained order with a strong hand, but was no more severe than his security demanded. Forests were still retained by Kings for their hunting of boars and stags. A master forester maintained them. The boundaries of the Royal Forests were enlarged. They comprised almost one-third of the kingdom. Certain inhabitants thereof supplied the royal foresters with meat and drink and received certain easements and rights of common therein. The forest law reached the extreme of severity and cruelty under Henry I. Punishments given included blinding, emasculation, and execution. Offenders were rarely allowed to substitute a money payment. When fines were imposed they were heavy. A substantial number of barons and monasteries were heavily in debt to the Jews. The interest rate was 43% (2d. per pound per week). The king taxed the Jews at will. - The Law - Henry restored the death penalty (by hanging) for theft and robbery, but maintained William I's punishment of mutilation by blinding and severing of limbs for other offenses, for example, bad money. He decreed in 1108 that false and bad money should be amended, so that he who was caught passing bad denarii should not escape by redeeming himself but should lose his eyes and members. And since denarii were often picked out, bent, broken, and refused, he decreed that no denarius or obol, which he said were to be round, or even a quadrans, if it were whole, should be refused. (Money then reached a higher level of perfection, which was maintained for the next century.)
