More than four hundred years ago the waters of the Thames were at some states of the tide too turbid for use, and accordingly in the reign of Henry VI., the Wardens of the Brewers’ Company were commanded not to take water for brewing from the Thames when it was disturbed, but to wait till low water and the turn of the tide. In Queen Elizabeth’s reign the Thames was beginning to acquire an evil repute, if we may believe the author of _Pierce Penilesse, his supplication to the Deuill_ (1592), who refers to the London Brewers in terms of contempt. “Some” says he, “are raised by corrupt water, as gnats, to which we may liken brewers, that, by retayling _filthie Thames water_, come in a few yeres to be worth fortie or fiftie thousand pound.” Stow remarks of the London Brewers that “for the more part they remain near the friendly waters of the Thames.” In his time many brewhouses were gathered together in the parish of St. Catharine, near the Tower, and are distinguished on the map of London given in the Civitates Orbis by the name of “Beer Houses.” Many years ago a canal led up from the Thames to the Stag Brewery at Pimlico, and provided that now famous brewhouse with water. All through the reign of Elizabeth, and for some time afterwards, the Thames in the neighbourhood of the City, continued to afford the greater part of the water used by the London Brewers. Until the New River water was brought to London, an event which took place in the time of James I., the Thames would naturally furnish the chief supply. The regulations in force touching the Thames water, had regard to the manner in which it was carried from the river to the Breweries, and did not in any way seek to restrict the use of the water as unfit for its purpose. For instance, in the third year of Elizabeth’s reign the Wardens of the Brewers were called before the Common Council and {124} charged not to fetch the water of the Thames in a “liquor-cart,”[43] but to make use of “boge” horses (horses carrying boges, _i.e._ water-barrels), according to the ancient laws and ordinances. The command was subsequently relaxed in favour of brewers living close to the River, and drawing water from “the Water-gate at the Tower Hill or at the Whitefriars.” The reason for this regulation is not stated, but the partial removal of the restriction would seem to show that it was intended to prevent the crowding of the narrow thoroughfares of the City with brewers’ carts passing and repassing. The horse with his “boge” would pass another horse with ease, while two “liquor carts” meeting would certainly block the way. This interpretation is rather confirmed by a subsequent regulation, made three years before the Great Fire cleared away many of the narrow lanes of the City, that brewers’ drays should not go abroad in the streets after 11 a.m. on account of the obstruction to traffic thereby occasioned.
