The disagreement between Geoffrey and Matilda ran its course as a family quarrel. It might endanger the future of Henry's plans, but it caused him no present difficulty. His continental position was now, indeed, secure and was threatened during the short remainder of his life by none of his enemies, though his troubles with his son-in-law were not yet over. The defeat of Robert and the crushing of the most powerful nobles had taught the barons a lesson which did not need to be repeated, and England was not easily accessible to the foreign enemies of the king. In Normandy the case was different, and despite Henry's constant successes and his merciless severity, no victory had been final so long as any claimant lived who could be put forward to dispute his possession. Now followed some years of peace, in which the history of Normandy is as barren as the history of England had long been, until the marriage of Matilda raised up a new claimant to disturb the last months of her father's life. During Henry's last stay in Normandy death had removed one who had once filled a large place in history, but who had since passed long years in obscurity. Ranulf Flambard died in 1128, having spent the last part of his life in doing what he could to redeem the earlier, by his work on the cathedral of Durham, where in worthy style he carried on the work of his predecessor, William of St. Calais. Soon after died William Giffard, the bishop whom Henry had appointed before he was himself crowned, and in his place the king appointed his nephew, Henry of Blois, brother of Count Stephen, who was to play so great a part in the troubles that were soon to begin. About the same time we get evidence that Henry had not abandoned his practice of taking fines from the married clergy, and of allowing them to retain their wives. The year 1130, which Henry spent in England, is made memorable by a valuable and unique record giving us a sight of the activities of his reign on a side where we have little other evidence. The Pipe Roll of that year has come down to us.[25] The Pipe Rolls, so called apparently from the shape in which they were filed for preservation, are the records of the accounting of the Exchequer Court with the sheriffs for the revenues which they had collected from their counties, and which they were bound to hand over to the treasury. From a point in the reign of Henry's grandson, these rolls become almost continuous, and reveal to us in detail many features of the financial system of these later times. This one record from the reign of the first Henry is a slender foundation for our knowledge of the financial organization of the kingdom, but from it we know with certainly that this organization had already begun as it was afterward developed.
