My Cambridge tutor was bubbling over with pleasure one morning in 1962 after reading Dorothy Wordsworth’s journal, the one she kept between 1800 and 1803 when living with her poet brother William at Dove Cottage in the Lake District. What he had been particularly taken with was something she wrote on 14 May 1802 when the two had been walking in the woods alongside Grasmere: ‘William teased himself with seeking an epithet for the Cuckow.’ I never forgot this slightly comical picture of the creative process, but it was almost thirty years before I came to read her journal myself when doing a book on Coleridge among the lakes and mountains.
