He had to look after the household serfs too, and set them to work.

He had to see about storing, or selling, or sending off to the monastery the produce of the estate and of the tenants' rents; and every year he had to present a full and detailed account of his stewardship to the abbot.

He had a manse of his own, with services and rents due from it, and Charlemagne exhorted his stewards to be prompt in their payments, so as to set a good example.

Probably his official duties left him very little time to work on his own farm, and he would have to put in a man to work it for him, as Charlemagne bade his stewards do.

Often, however, he had subordinate officials called _deans_ under him, and sometimes the work of receiving and looking after the stores in the big house was done by a special cellarer.
That, in a few words, is the way in which the monks of St Germain and the other Frankish landowners of the time of Charlemagne managed their estates.
