Sir: If Mr Kavanagh wants to get rid of his

moles (Postscript, 8 September) he should buy one of those toy windmills that spin round on the end of a stick. You plant the base of the stick in the mole's run; and when the wind blows, the mole, disliking the vibration, moves off into your neigh- bour's ground.
