摘要：The survey of a thin accountancy book of the feudal estate of Barberà, belonging to the Military Order of Hospital of Jerusalem, allows us to know a little more about the lord's net income, the course of annual fieldwork, the feeding habits and notes for several kinds of prices and wages. Even though the reconstruction of the reckoning needs a lot of inferences, it seems clear that the direct farming by landlords was not very profitable if it was profitable at all; but it helped to the maintenance of the most important feudal and land income.
