All burgesses shall henceforth pay their taxes at the gildhall to the chamberlains when given notice or summoned by the sergeant. Any burgess thus forewarned three times and failing to come to pay after the third warning shall pay a surcharge of 1d. for every 12d. due in tax. And each further time he is warned to come and pay his tax and fails, a surcharge of a 1d. per 12d. shall be imposed, until the tax is paid in full.
