Egotism here becomes rather unavoidable. At Dumbarton Grange the library in which I wrote for some twelve years was lighted by three windows set side by side and opening outward. It was in the instant of unclosing one of these windows, on a fine afternoon in the spring of 1919, to speak with a woman and a child who were then returning to the house (with the day's batch of mail from the post office), that for no reason at all, I reflected it would be upon every personal ground.
