It was to Washington, therefore, that the centre of interest now shifted; and those who had lately returned from America were bombarded with enquiries about the feeling and condition of the United States. The corporate life of the Balfour mission came to an end with the welcome accorded to its head at the Guildhall and at the Mansion House luncheon on July 13th; and, when its members had reported their return to their departments, they were free to study the psychology of London in what, even then, was known to be the last phase of the war. Since 1914 they had been too busy to catch more than a passing glimpse of their friends as they flashed to and from the front or from their work at home; and the novels and memoirs of this period will be an untrustworthy guide to future social historians in so far as they suggest a life of unrelieved frivolity and pleasure-seeking when the greatest war effort had yet to be made. There were certainly days and nights of epidemic excitement, which occasionally turned to sporadic insanity; now, as in every phase of the war, there were men and women who made of the public disorganisation an excuse for abandoning all recognised restraints; but the general change was little more than a universal restlessness in which the nerves that had been kept tense by the daily demands of the war refused to be relaxed in hours of leisure. If there were more distractions in 1917 than in 1915, there was also more work done, and it was better organised; the novels and memoirs, naturally enough, give little space to daily routine; but it is less true to suggest that those who lived in London were grown indolent or callous to the war than that they had accommodated their private lives to public requirements. No one was surprised if a man went from his office to dinner without dressing or if he was made late for luncheon by a daylight air-raid. Informality, first imposed by necessity, was found to be amusing in itself; and an element of impromptu picnic crept into most of the parties of that time.
