Other restrictions were placed upon them. It was the sheriffs' duty also, upon the vigil of St. Michael, on vacating their office, to resign into the hands of the mayor for the time being the keys of Newgate, the cocket or seal of Newgate, and all other things pertaining unto the said sheriffwick. All the civic authorities, mayor, sheriffs, aldermen, and their servants, including the gaoler of Newgate, were forbidden to brew for sale, keep an oven, or let carts for hire; "nor shall they be regrators of provisions, or hucksters of ale, or in partnership with such." Penalties were attached to the breach of these regulations. It was laid down that any who took the oath and afterwards contravened it, or any who would not agree to abide by the ordinance, should be forthwith "ousted from his office for ever." It was also incumbent upon the sheriffs to put "a man sufficient, and of good repute, to keep the gaol of Newgate in due manner, without taking anything of him for such keeping thereof, by covenant made in private or openly." Moreover, the gaoler so appointed swore before the lord mayor and aldermen that "neither he nor any of them shall take fine or extortionate charge from any prisoner by putting on or taking off his irons, or shall receive moneys extorted from such prisoners." He was permitted to levy fourpence from each upon release, "as from ancient time has been the usage, but he shall take fees from no person at his entrance there;" indeed, he was warned that if he practised extortion he would be "ousted from his office," and punished at the discretion of the mayor, aldermen, and common council of the city.
