Enormous numbers of rooks and crows all over England, big ungainly scraggy-looking birds that gorge all day.  There is a water-cress bed nearby.  Where a stream widens out the cress has been planted over an area of about ½ an acre and is cut systematically as it grows – the whole thing being surmounted by a lifelike scare-crow armed with a dummy gun.  A big battle plane flew over us, quite near, at a terrific rate, then returning at a higher altitude, did a corkscrew dive, turning over and over like a shot bird; eventually righting itself and roaring away home to its roost.
