“In default of a smell the next best mnemonic is a tune. I have got tunes in my head for every war I have been to, and indeed for every critical or exciting phase in my life. Some day when my ship comes home, I am going to have them all collected in gramophone records, and then I will sit in a chair and smoke my cigar, while pictures and faces, moods and sensations long vanished return; and pale but true there gleams the light of other days.”
