Intermarriage had destroyed any distinction of Normans by look or speech alone, except for the Anglo-Saxon manor villeins, who worked the farm land and composed about two-thirds of the population. Villeins were bound to the land and could, on flight, be brought back to it. They could not give homage, but could give fealty. A villein had the equipment to farm, fish, make cheese, keep poultry, brew beer, hedge, and cut wood. Although the villeins could not buy their freedom or be freed by their lord, they became less numerous because of the preference of landholders for tenants motivated to perform work by potential loss of tenure. Also, the Crown's protection of all its subjects in criminal matters blurred the distinction between free and unfree men. The boroughs were dominated by lords of local manors, who usually had a house in the borough. Similarly, burgesses usually had farmland outside the borough. Many boroughs were granted, by the king or manor lord, the right to have a common seal for the common business of the town. Some boroughs were given the authority to confer freedom on the villein by enrolling him in their guild or allowing him to stay in the borough for a year and a day. The guilds met frequently in their drinking halls and drew up regulations for the management of their trade. Each borough was represented by twelve reputable burgesses. Each vill was represented by a reeve and four reputable men. Certain towns sponsored great seasonal fairs for special goods, such as cloth. About 5% of the population lived in towns. In the early 1180s, the horizontal-axle windmill was invented, probably in eastern England, on the analogy of the horizontal-axle watermill. It was very useful in flat areas where streams were too slow for a watermill unless a dam were built. But a dam often flooded agricultural land. Some watermill wheels were moved by tidal currents. London guilds of craftsmen such as weavers, fullers, bakers, loriners (makers of bits, spurs, and metal mountings of bridles and saddles), cordwainers (makers of leather goods such as shoes), pepperers, and goldsmiths were licensed by the King, for which they paid him a yearly fee. There were also five Bridge Guilds (probably raising money for the future construction of London Bridge in stone) and St. Lazarus' Guild. The wealthy guilds, which included the goldsmiths, the pepperers, and three bridge guilds had landholding members who had been thegns or knights and now became a class of royal officials: the King's minters, his chamberlain, his takers of wines, his collectors of taxes. The weavers of Oxford paid 27s. [two marks] to have a guild. The shoemakers paid 67s. [five marks]. In 1212, master carpenters, masons, and tilers made 3d. per day, their servers (the journeymen of a later time) made 1 1/2 d., free stone carvers 2 1/2 d., plasterers and daubers, diggers and sievers less. All received food in addition or 1 1/2 d. in its stead.
