So you understand the roaring wave of fear that swept through the
greatest city in the world just as Monday was dawning--the stream of
flight rising swiftly to a torrent, lashing in a foaming tumult round
the railway stations, banked up into a horrible struggle about the
shipping in the Thames, and hurrying by every available channel
northward and eastward.  By ten o'clock the police organisation, and
by midday even the railway organisations, were losing coherency,
losing shape and efficiency, guttering, softening, running at last in
that swift liquefaction of the social body.
