A very good series also exists for St Mary de Pré, near St Albans, kept by the wardens 1341-57 and by the Prioress 1461-93[266]; and there is in the Record Office a valuable little book of accounts kept by the treasuresses of Gracedieu (Belton) during the years 1414-18, which has been made familiar to many readers by the use made of it by Cardinal Gasquet in _English Monastic Life_[267]. Very full and interesting accounts have also survived from St Radegund's Cambridge (1449-51, 1481-2)[268], Catesby (1414-45)[269] and Swaffham Bulbeck (1483-4)[270]. These are all prioresses' or treasuresses' accounts of the total expenditure of the different houses; but there are in existence also a few obedientiaries' accounts, chambresses' accounts from St Michael's Stamford and Syon and cellaresses' accounts from Syon[271]. An analysis of these accounts shows, better than any other means of information, the various sources from which a medieval nunnery drew its income, and the chief classes of expenditure which it had to meet. It will therefore be illuminating to consider in turn the credit and debit side of a monastic balance sheet.
It is perhaps unnecessary to postulate that since monastic houses differed greatly in size and wealth, the sources of their income would differ accordingly. A very poor house might be dependent upon the rents and produce of one small manor; a large house sometimes had estates all over England. The entire income of Rothwell in Northamptonshire was derived from one appropriated rectory, valued in the _Valor_ at £10. 10_s._ 4_d._ gross and at £5. 19_s._ 8_d._ net per annum[272]. The Black Ladies of Brewood (Staffs.) had an income of £11. 1_s._ 6_d._ derived from demesne in hand, rents and alms[273]. On the other hand Dartford in Kent held lands in Kent, Surrey, Norfolk, Suffolk, Wiltshire, Wales and London[274], the Minoresses without Aldgate held property in London, Hertfordshire, Kent, Berkshire, Staffordshire, Derbyshire, Bedfordshire, Buckinghamshire, Norfolk and the Isle of Wight[275]. The splendid Abbey of Syon held land as far afield as Lancashire and Cornwall, scattered over twelve counties[276]. Similarly the proportionate income derived from house-rents and land-rents would differ with the geographical situation of the nunnery. London convents, for instance, would draw a large income from streets of houses, whereas a house in the distant dales of Yorkshire would be dependent upon agriculture. At the time of the _Valor_ twenty-two nunneries were holding urban tenements in fifteen towns, amounting in total value to £1076. 0_s._ 7_d._, but of this sum £969. 11_s._ 10_d._ was held by the seven houses in London[277]. With this proviso the conclusion may be laid down that the money derived from the possession of agricultural land, and in particular the rents paid by tenants in freehold, copyhold, customary and leasehold land, was the mainstay of the income paid into the hands of the treasuress.
