Some villeins bought out their servitude by paying a substitute to do his service or paying his lord a firm (from hence, the words farm and farmer) sum to hire an agricultural laborer in his place. This made it possible for a farm laborer to till one continuous piece of land instead of scattered strips. Looms were now mounted with two bars. Women did embroidery. The clothing of most people was made at home, even sandals. The village tanner and bootmaker supplied long pieces of soft leather for more protection than sandals. Tanning mills replaced some hand labor. The professional hunter of wolves, lynx, or otters supplied head coverings. Every village had a smith and possibly a carpenter for construction of ploughs and carts. The smith obtained coal from coal fields for heating the metal he worked. Horse harnesses were homemade from hair and hemp. There were watermills and/or windmills for grinding grain, for malt, and/or for fulling cloth. The position of the sails of the windmills was changed by manual labor when the direction of the wind changed. Most men wore a knife because of the prevalence of murder and robbery. It was an every day event for a murderer to flee to sanctuary in a church, which would then be surrounded by his pursuers while the coroner was summoned. Usually, the fugitive would confess, pay compensation, and agree to leave the nation permanently. County courts were the center of decision-making regarding judicial, fiscal, military, and general administrative matters. The writs for the conservation of the peace, directing the taking of the oath, the pursuit of malefactors, and the observance of watch and ward, were proclaimed in full county court; attachments were made in obedience to them in the county court. The county offices were: sheriff, coroner, escheator, and constable or bailiff. There were 28 sheriffs for 38 counties. The sheriff was usually a substantial landholder and a knight who had been prominent in the local court. He usually had a castle in which he kept persons he arrested. He no longer bought his office and collected certain rents for himself, but was a salaried political appointee of the King. He employed a deputy or undersheriff, who was an attorney, and clerks. If there was civil commotion or contempt of royal authority, the sheriff of the county had power to raise a posse of armed men to restore order. The coroner watched the interests of the crown and had duties in sudden deaths, treasure trove, and shipwreck cases. There were about five coroners per county and they served for a number of years. They were chosen by the county court. The escheator was appointed annually by the Treasurer to administer the Crown's rights in feudal land, which until 1242 had been the responsibility of the sheriff. He was usually chosen from the local gentry. The constable and bailiff operated at the hundred and parish [the geographical area of a church's members] level to detect crime and keep the peace.
