24-65 Correspondence between corn-factors i.e. between John Baynter of Amlwch, Edward Williams and John Jones of Liverpool. Williams has only two letters in which he grumbles at the high market of Amlwch, and gives a dark picture of the activities of both burglars and press-gang in Liverpool. John Jones was on intimate terms with Paynter; in fact he was part proprietor of the Mona Mill itself. Relations between the two become a little strained at times. Several of the letters have valuable account-sheets attached and throughout they are of first-hand importance for the state of the Liverpool corn-market during the latter years of the Napoleonic wars and the difficult period which followed.
