I. THE first of the king's ordinary revenues, which I shall take notice of, is of an ecclesiastical kind; (as are also the three succeeding ones) viz. the custody of the temporalties of bishops; by which are meant all the lay revenues, lands, and tenements (in which is included his barony) which belong to an archbishop's or bishop's see. And these upon the vacancy of the bishoprick are immediately the right of the king, as a consequence of his prerogative in church matters; whereby he is considered as the founder of all archbishopricks and bishopricks, to whom during the vacancy they revert. And for the same reason, before the dissolution of abbeys, the king had the custody of the temporalties of all such abbeys and priories as were of royal foundation (but not of those founded by subjects) on the death of the abbot or prior[a]. Another reason may also be given, why the policy of the law hath vested this custody in the king; because, as the successor is not known, the lands and possessions of the see would be liable to spoil and devastation, if no one had a property therein. Therefore the law has given the king, not the temporalties themselves, but the _custody_ of the temporalties, till such time as a successor is appointed; with power of taking to himself all the intermediate profits, without any account to the successor; and with the right of presenting (which the crown very frequently exercises) to such benefices and other preferments as fall within the time of vacation[b]. This revenue is of so high a nature, that it could not be granted out to a subject, before, or even after, it accrued: but now by the statute 14 Edw. III. st. 4. c. 4 & 5. the king may, after the vacancy, lease the temporalties to the dean and chapter; saving to himself all advowsons, escheats, and the like. Our antient kings, and particularly William Rufus, were not only remarkable for keeping the bishopricks a long time vacant, for the sake of enjoying the temporalties, but also committed horrible waste on the woods and other parts of the estate; and, to crown all, would never, when the see was filled up, restore to the bishop his temporalties again, unless he purchased them at an exorbitant price. To remedy which, king Henry the first[c] granted a charter at the beginning of his reign, promising neither to sell, nor let to farm, nor take any thing from, the domains of the church, till the successor was installed. And it was made one of the articles of the great charter[d], that no waste should be committed in the temporalties of bishopricks, neither should the custody of them be sold. The same is ordained by the statute of Westminster the first[e]; and the statute 14 Edw. III. st. 4. c. 4. (which permits, as we have seen, a lease to the dean and chapter) is still more explicit in prohibiting the other exactions. It was also a frequent abuse, that the king would for trifling, or no causes, seise the temporalties of bishops, even during
