For many years I have been accustomed to make notes on random leaves of the things in Life and Thought which have chanced to strike my attention. Such records of personal reaction to the outer and inner world have been helpful to my work, and so had their uses. But as one grows older the possibilities of these uses become more limited. One realises in the Autumn that leaves no longer have a vital function to perform; there is no longer any need why they should cling to the tree. So let them be scattered to the winds! It is inevitable that such Leaves cannot be judged in the same way as though they constituted a Book. They are much more like loose pages from a Journal. Thus they tend to be more personal, more idiosyncratic, than in a book it would be lawful for a writer to be. Often, also, they show blanks which the intelligence of the reader must fill in. At the best they merely present the aspect of the moment, the flash of a single facet of life, only to be held in the brain provided one also holds therein many other facets, for the fair presentation of the great crystal of life. So it comes about that much is here demanded of the Reader, so much that I feel it rather my duty to warn him away than to hold out any fallacious lures
