Smithfield was a field outside the city gates at which horses were sold and raced. In 1372, the horse dealers and drovers petitioned for a tax on animals sold there to pay for cleaning the field. The city ordinance reads as follows: "On Wednesday next after the Feast of St. Margaret the Virgin came reputable men, the horse dealers and drovers, and delivered unto the mayor and aldermen a certain petition in these words: 'To the mayor, recorder, and aldermen show the dealers of Smithfield, that is to say, the coursers and drovers, that for the amendment of the said field they have granted and assented among them that for the term of three years next ensuing after the date of this petition for every horse sold in the said field there shall be paid one penny, for every ox and cow one halfpenny, for every eight sheep one penny, and for every swine one penny by the seller and the same by the purchaser who buys the same for resale.` Afterwards, on the eleventh day of August in the same year, Adam Fernham, keeper of the gaol at Newgate, Hugh, Averelle, bailiff of Smithfield, and William Godhewe, weaver, were chosen and sworn faithfully to collect and receive the said pennies in form aforesaid and to clean the field of Smithfield from time to time during such term of three years when necessary." Many London houses were being made from stone and timber and even brick and timber, instead of just timber and mud. However, chimneys were still a luxury of the rich. They were made of stone, tile, or plaster. There were windows of glass and a guild of glaziers was chartered by the King. A typical merchant's house had a cellar; a ground floor with a shop and storage space; a first floor with a parlor to receive guests, a spacious hall for dining, and perhaps a kitchen; and at the top, a large family bedroom and a servant's room. Stairwells between floors had narrow and winding steps. Many single-roomed houses added a second-floor room for sleeping, which was approached by a wooden or stone staircase from the outside. Their goods were displayed on a booth outside the door of the house or hung in the windows. They were stored at night in the cellar. Over the booths swung huge signs, which had to be nine feet above street level to allow a man on horseback to ride underneath. There were no sidewalks. Street repair work for wages was supervised by a stone master. The streets sloped down from the middle so that the filth of the streets would run down the sides of the road. There were many wood chips in the streets due to cutting up of firewood before taking it indoors. People often threw the rubbish from their houses onto the street although they were supposed to cart it outside the city walls and to clean the frontage of their houses once a week. Dustmen scavenged through the rubbish on the streets. Pigs and geese were no longer allowed to run at large in the streets, but had to be fed at home. There
