As economic activity in London became more complex and on a larger scale in the 1200s, some craftsmen were brought under the control of other crafts or merchants. The bakers fell under the control of the wholesale grain dealers; the weavers became pieceworkers for rich cloth merchants; the blademakers and shearers were employed by cutlers; coppersmiths were controlled by girdlers; fullers were controlled by entrepreneurial dyers; and the painters, joiners, and lorimers were controlled by the saddlers. Guilds moved their meeting places from churches, which were now too small, to guild halls. The controlling officers of the large guilds met at the Guildhall, which became the seat of mayoral authority. London streets in existence by this time include Cordwainer, Silver, Cannon (Candlewick), and Roper. Lanes included Ironmonger, Soper, Spurrier, Lad (ladles), Distaff, Needles, Mede, Limeburner, and Hosier. Fighting among groups was common in London. There was a street fight on a large scale in 1327 between the saddlers and a coalition of joiners, painters, and lorimers (makers of metal work of saddles). Much blood was shed in the street battle between the skinners and the fishmongers in 1340. There was a city ordinance that no one except royal attendants, baronial valets, and city officials were to go about armed. Disputes among neighbors that were brought to court included the use and upkeep of party walls, blocked and overflowing gutters, cesspits too close to a neighbor's property, noisy tenants, loss of light, and dangerous or overhanging structures. In 1275, a goldsmith was chief assay-master of the King's mint and keeper of the exchange at London. The king gave the Goldsmiths' Company the right of assay [determination of the quantity of gold or silver in an object] and required that no vessels of gold or silver should leave the maker's hands until they had been tested by the wardens and stamped appropriately. In 1279, goldsmith William Farrington bought the soke of the ward containing the goldsmiths' shops. It remained in his family for 80 years. A patent of 1327 empowered the guild to elect a properly qualified governing body to superintend its affairs, and reform subjects of just complaint. It also prescribed, as a safeguard against a prevailing fraud and abuse, that all members of the trade should have their standing in Cheapside or in the King's exchange, and that no gold or silver should be manufactured for export, except that which had been bought at the exchange or of the trade openly.
