Note 295:2 — KUBLA KHAN[295:1]:

There can be little doubt that Coleridge should have written 'the summer of 1798'. In an unpublished MS. note dated November 3, 1810, he connects the retirement between 'Linton and Porlock' and a recourse to opium with his quarrel with Charles Lloyd, and consequent distress of mind. That quarrel was at its height in May 1798. He alludes to distress of mind arising from 'calumny and ingratitude from men who have been fostered in the bosom of my confidence' in a letter to J. P. Estlin, dated May 14, 1798; and, in a letter to Charles Lamb, dated [Spring] 1798, he enlarges on his quarrel with Lloyd and quotes from Lloyd's novel of Edmund Oliver which was published in 1798. See Letters of Samuel Taylor Coleridge, 1895, i. 245, note 1. I discovered and read for the first time the unpublished note of November 3, 1810, whilst the edition of 1893 was in the press, and in a footnote to p. xlii of his Introduction the editor, J. D. Campbell, explains that it is too late to alter the position and date of Kubla Khan, but accepts the later date (May, 1798) on the evidence of the MS. note.
