All residents of Lynn, whatever their status, shall have their grain ground at the common mill if the mill is able to handle their demands. Henceforth if anyone has his grain ground at any mill outside of town when the common mill could have ground it, he shall forfeit the grain or the flour produced outside town, which may be confiscated by the common sergeant or someone else and put to the use of the community.

[The mill had been built in the 1390s to create a new source of revenue for the borough (see the notes appended to the mill's entry in the rental); one of the chamberlains was assigned the responsibility of keeping track of mill finances, and there even appears to have been a contrarotulator assigned to keep duplicate accounts, as a control on honest accounting. Between 29 September 1398 and 25 March 1399 the borough had obtained revenues of £33.3s.4d from the mill, through fees for grinding 1,670 qt. of grain (at 4d. a quarter), although much of this had to be reinvested in mill maintenance. After March 25 the corn mill, together with a fulling mill, two cottages and a garden, were farmed to John Miller for three years at £50 a year, and farming out henceforth became the preferred approach for dealing with the mills. However, it proved difficult persuading bakers and other townsmen to give their business to the town mill, and eventually it became necessary to apply compulsion through this ordinance. Four bakers were appointed to supervise adherence to the ordinance. Fines were later introduced as an added deterrent.]
