The serf occupied a position in rural society which it is difficult for us to understand. He was not a slave, such as was usual in the Southern States of the American Union before the Civil War; he was neither a hired man nor a rent-paying tenant-farmer, such as is common enough in all agricultural communities nowadays. The serf was not a slave, because he was free to work for himself at least part of the time; he could not be sold to another master; and he could not be deprived of the right to cultivate land for his own benefit. He was not a hired man, for he received no wages. And he was not a tenant-farmer, inasmuch as he was "attached to the soil," that is, he was bound to stay and work on his land, unless he succeeded in running away or in purchasing complete freedom, in which case he would cease to be a serf and would become a freeman. [Sidenote: Obligations of the Serf to the Lord] To the lord of the manor the serf was under many and varied obligations, the most essential of which may be grouped conveniently as follows: (1) The serf had to work without pay two or three days in each week on the strips of land and the fields whose produce belonged exclusively to the nobleman. In the harvest season extra days, known as "boon-days," were stipulated on which the serf must leave his own work in order to harvest for the lord. He also might be called upon in emergencies to draw a cord of wood from the forest to the great manor- house, or to work upon the highway (_corvée_). (2) The serf had to pay occasional dues, customarily "in kind." Thus at certain feast-days he was expected to bring a dozen fat fowls or a bushel of grain to the pantry of the manor-house. (3) Ovens, wine-presses, gristmills, and bridges were usually owned solely by the nobleman, and each time the peasant used them he was obliged to give one of his loaves of bread, a share of his wine, a bushel of his grain, or a toll-fee, as a kind of rent, or "banality" as it was euphoniously styled. (4) If the serf died without heirs, his holdings were transferred outright to the lord, and if he left heirs, the nobleman had the rights of "heriot," that is, to appropriate the best animal owned by the deceased peasant, and of "relief," that is, to oblige the designated heir to make a definite additional payment that was equivalent to a kind of inheritance tax.
