"SOLE, LUNDY, Fastnet, Irish Sea..." As listeners, viewers and readers, we are conservative creatures. But the Radio 4 audience is the most conservative of all. They represent a sort of National Trust of the airwaves, devoted to the preservation of the fabric of broadcasting schedules. Accidental survivals from an earlier age are treated with reverence. The shipping forecast, the six o'clock bongs, the seagulls on Roy Plomley's desert island. Millions of domestic routines have been displaced by the shifting of The Archers. Millions of ears have been offended by "30 minutes of news and comment from the BBC" instead of the 40 of The World At One.

And yet... the surprising thing about the changes brought in by James Boyle, controller of Radio 4, is how little protest there has been. Now, a month on from the small earthquake we can add: not many hurt. This is an extraordinary achievement for Mr Boyle.

What is significant is that middle England has not marched on Broadcasting House to protest. They are sleeping safely in their beds, soothed by familiar litanies. "Rockall, Malin, Hebrides... "
