5io The Period of Constitution Making In the reign of Henry II. the Exchequer accounting and auditing was held regularly at Westminster, though it could then and for long afterwards, upon special occa- sion, be held elsewhere. The treasury was still at Win- chester, but it had now become what it was to start with, a storehouse. But the receipt of much money at West- minster made a temporary storage there or in London a necessity; and the packing of it in chests and the carriage of these to Winchester were burdensome. Quite naturally the treasury at London came to supersede that at Win- chester, and this was accomplished by the early part of Henry's IIL's reign. It was one of the many changes in the late twelfth and early thirteenth centuries which were making London and Westminster the recognised seat of government. So far as the treasury had been in any sense a department of government it was now ab- sorbed by the Exchequer, and there was no treasury as a separate financial department until after the middle ages. By the late twelfth century the Exchequer was manned largely by skilled specialists in finance, and before long Its judicial side was specialised, professionalised—the Barons of the Exchequer were justices of a court of special competence, not ordinary feudal barons.1 This means that the Exchequer had gone, or was very rapidly going, "out of court." It did not follow the king, it was not a part of his personal entourage or household, its members were not giving him counsel on general policy or tin- specialised points of administrative detail.

The Chancellor pretty definitely left the Exchequer at the beginning of John's reign. His clerk remained, but hardly as the Chancellor's represen- tative. The king appointed him. He was keeper of the Exchequer seal, a duplicate of the king's 1 See above, p. 176 and note 3.
