122 IL FROM THE llOO'S TO THE 1800'S law and custom and procedure. Under Henry I. two courts, the Exchequer and the Curia Regis, had control of all the financial and judicial business of the kingdom. The Ex- chequer filled a far more important place in the national life than the Curia Regis, for the power of the king was simply measured by the state of the treasury, when wars began to be fought by mercenaries, and justice to be administered by paid oflScials. The court had to keep a careful watch over the provincial accounts, over the moneys received from the king's domains, and the fines from the local courts. It had to regulate changes in the mode of payment as the use of money gradually replaced the custom of payments in kind.

In a second chamber, the Exchequer of Receipt, the sheriff or tax-farmer paid in his dues and took his receipts. The accounts were carefully entered on the treasurer's roll, which was called from its shape the Great Roll of the Pipe, and which may still be seen in our Record Office; the chan- cellor kept a duplicate of this, known as the Roll of the Chancery ; and an officer of the king registered in a third Roll matters of any special importance. Before the death of Henry I. the vast amount and the complexity of business in the Exchequer Court made it impossible that it should any longer be carried on wholly in London. The " Barons '* began to travel as itinerant judges through the country; as the king's special officers they held courts in the provinces,
