MANORIAL TREATISES 155 books of estate management which were written down in the late thirteenth century, such as Fleta, Walter of Henley and others. It is necessary, however, to add a word of caution at the outset concerning the use of these works. Leopold Delisle noted the wealth of early handbooks on estate management which have survived in England, and he lamented that no such records survived in France. But they have not been an unmixed blessing. Many students of manorial documents written in the late thirteenth and fourteenth centuries will have noticed how diffi- cult it is to find in Court Rolls or in Ministers' Accounts many examples which will bear out the statements of these contem- porary manuals of estate management. Walter of Henley or Fleta can tell us with a wealth of confident detail the exact duties of, say, the sergeant (serviens), the bailiff and the reeve. The sergeant, they say, does this and this; the bailiff may do that and that; while the reeve is restricted to exercising his authority here and here. The documents, however, tell us quite another story, and show us the sergeant usurping the duties of bailiff or of reeve; and worse still, the underlings daring to act in ways in which only their superiors should do. The question at once arises: Which are we to accept as giving the more trustworthy witness—the treatises or the various types of manorial records? The question would seem to be easily answered a priori in favour of the docu- ments, were it not for the fact that the influence of the treatises on modern scholars has been so great that almost all accounts of the working of the medieval manor are based on some such con- dition of affairs as is set forth in the pages of Fleta, etc. And this, no doubt, is the inevitable evolution of the study of these intricate matters: first, attention is paid to the general theory and contemporary exposition, and only later comes scrutiny of the minutiae. Thus the late Dr Cunningham writes: The bailiff was appointed by the lord to look after the whole estate in detail; he was directly responsible to the lord for everything con- nected with the prosperity of the estate, and had to account in great detail for everything under his charge----The (reeve) seems to have been the official representative of the villeins, who was responsible for them.1 1 Walter of Henleyp, Intro, xii, xiii.
