These tinners are distinguished from foreigners (for so they term those that are no tinners,) by many sundry immunities and freedoms: as not to be mustered before the lord lieutenant or his deputies; they are not to be impleaded for any tin cause but in their own courts and before the warden and his deputy, and by them to be commanded, trained, and mustered.
