John Wetherall, a revenue officer, reports to the Chief of Commissioners and Governors of Irish Revenue on smuggled goods identified as originating from the Isle of Man. The report details classification methods for recognizing Manx contraband (tea in small casks, tobacco in trusses, spirits in ankers) and lists goods seized and sold, including tea, tobacco, brandy, geneva, rum, and foreign textiles. The letter reflects ongoing customs enforcement concerns during the period leading up to the 1765 Revestment.
