* * The gyratory system of traffic in Parliament Square

has been a great success. Some traffic has a long way round assigned to it, but there are practically no blocks. The clearance at this end of Whitehall, however, empha- sizes the blocks at the other end. Perhaps we shall soon have a merry-go-round experiment in Trafalgar Square, as well as at several similar junctions.
