12 some of the pieces were about 18 inches long by 10 or 12 inches wide and the whole quantity of bark littering the pavement was quite extraordinary. I knew it is a feature of plane trees to shed their bark, giving the characteristic mottled appearance, but the extent to which this had happened led me to suspect disease or possibly the attentions of grey squirrels. Hurrying on my way the observations were momentarily forgotten. A short time later, there appeared in the Guardian newspaper a "Country Diary" article which mentioned the phenonemon, commenting that this dramatic discarding of bark was currently widespread so led me to observe the London Plane more closely. Two of our three trees bore completely bare branches by this time with many patches on the tree trunks as well. In central London particularly along the Embankment the same thing can be observed and during the winter months the trees made a colourful sight with their limbs pointing like yellow ochre painted fingers to the sky. In areas such as Newham where roadside trees are annually chopped of all potential branches and twigs leaving only trunks with ugly knobbly tops, this shedding of bark is still apparent in some cases almost the whole of the tree is bare; generally the loss is largely from the upper branches of unpruned trees. My travels during the winter covered an area roughly bounded by Ely in the north, Reading in the west, southwards to Brighton and eastwards to Southend, and the phenonenon of
