Here, as at Usk, Peckham appointed in addition a master to look after their affairs[743]. At the disorderly house of Arthington Isabella Couvel was in 1312 associated with the Prioress Isabella de Berghby, but the Prioress seems to have resented the appointment and promptly ran away[744]. In the Exeter diocese Bishop Stapeldon made Joan de Radyngton coadjutress to Petronilla, Abbess of Canonsleigh in 1320[745]; and in the diocese of Bath and Wells Bishop Ralph of Shrewsbury in 1335 appointed two coadjutresses to Cecilia de Draycote, Prioress of White Hall, Ilchester, and in 1351, when his visitation had revealed many scandals at Cannington, including the simoniacal admission of nuns and unauthorised sale of corrodies by the Prioress, the Bishop, instead of depriving her "tempered the rigour of the law with clemency" and appointed two coadjutresses without whose consent she was to do nothing[746]. Bishop Alnwick made use of this method of controlling a superior in several cases where serious mismanagement had come to light at his visitation[747], and other instances of this method of controlling the administration of a superior might be multiplied from the episcopal registers. The appointment of treasuresses and of coadjutresses and the provision for due consultation of the chapter, custody of the common seal and presentment of accounts had the purpose of safeguarding the nuns against reckless expenditure or maladministration by the head of the house, and, where the injunctions of the Visitor were carried out, such precautions doubtless proved of use. Some further check was, however, necessary, to safeguard the nuns against themselves, and to prevent the whole convent from rash sales of land, alienation of goods and from all those other improvident devices for obtaining ready money, to which they were so much addicted. The Bishop often attempted to impose such a check by forbidding certain steps to be taken without his own consent. The business for which an episcopal licence was necessary usually comprised the alienation of land or its lease for life or for a long term of years, the sale of any corrodies or payment of any fees or pensions, and (as has already been pointed out) the reception of new inmates, who might overcrowd the house and thus impose a strain upon its revenues[748]. Other business, such as the sale of woods, was sometimes included[749]. The prohibition of corrodies, fees and pensions was doubtless intended to protect the nuns against the exactions of patrons and other persons, who claimed the right to pension off relatives or old servants by this means, as well as against their own improvidence in selling such doles for inadequate sums of ready money. As typical of such prohibitions may be quoted Alnwick's injunction (given in two parts) to Harrold in 1442-3:
