If some uncomplex minded and even moderately articulate man or woman, living in some small, ordinary respectable London house and going about his or her work in the customary way, had been prompted by chance upon June 29th, 1914, to begin to keep on that date a day-by-day diary of his or her ordinary life, the effects of huge historic events, as revealed by the every-day incidents to be noted in the streets, to be heard in his neighbours' houses as well as among his fellow workers, to be read in the penny or half-penny newspapers, would have resulted--if the record had been kept faithfully and without any self-conscious sense of audience--between 1914 and 1918 in the gradual compiling of a human document of immense historical value. Compared with it, the diaries of Defoe and Pepys would pale and be flavourless.

It can also without any special intellectual effort be imagined that the record might have begun with some such seemingly unprophetic entry as follows:--
