One of the triumphs of civilisation, Peter Walsh thought. It is one of the triumphs of civilisation, as the light high bell of the ambulance sounded. Swiftly, cleanly the ambulance sped to the hospital, having picked up instantly, humanely, some poor devil; some one hit on the head, struck down by disease, knocked over perhaps a minute or so ago at one of these crossings, as might happen to oneself. That was civilisation. It struck him coming back from the East--the efficiency, the organisation, the communal spirit of London.
