Under his orders every villein was bound to do a certain amount of “week-work”--to plough, sow, or reap, or otherwise labour on the demesne land a certain number of days every week; generally the obligation, on every virgate held in villenage, was for two or three days a week throughout the year, sometimes with an extra day at harvest-tide. The customary dues and services varied with the special custom of each manor; they consisted partly of payments either in kind or money, or both, and partly of services such as hewing, carting, and drying wood, cutting turf, making thatch, making malt, mowing and carrying hay, putting up fences, providing ploughs and labour for a specified length of time at particular seasons, ploughing, sowing, harrowing and reaping a given extent of the demesne land. Some of the rents were paid by the discharge of a special duty; the cowherds, oxherds, shepherds, swineherds, usually held a piece of land “by their service,” that is, in consideration of their charge over the flocks and herds of the lord; sometimes we find a further labour-rent paid by their wives, who winnow and reap so much corn on the demesne.[174] Many of the cotters doubtless held their little dwellings on a similar tenure, by virtue of their offices as the indispensable craftsmen of the village community, such as the blacksmith, the carpenter, or the wheelwright. The mill, too, an important institution on every large manor, paid a fixed money rent, and sometimes a tribute of fish from the mill-stream.[175] [173] “Præcaria” or “præcationes.” [174] _Liber Niger_ (App. to Chron.
