It was heartening to read that Royal Mail is cutting its carbon emissions by transferring mail from air to road (Royal Mail goes ahead with cuts to UK flights despite takeover, 7 July). Could I suggest an even more radical idea, which I know may sound totally implausible, that of travelling post offices on trains? (“This is the night mail crossing the border, / Bringing the cheque and the postal order”)

• It’s great that the Guardian cartoonist Ben Jennings has created his own version of Hogarth’s A Rake’s Progress (‘It’s like Where’s Wally in broken Britain’: Ben Jennings on his Tory-era take on A Rake’s Progress, 9 July). But no mention of Grayson Perry’s marvellous tapestries on the same theme, which have been touring the UK and are now at the Pitzhanger gallery in Ealing, west London.
