Note About the cedarn alleys — MILTON’S MINOR POEMS.
Reading edition
990. About the cedarn alleys: about the pathways through cedar groves. Coleridge, in Kubla Khan, has the line, “Down the green hill athwart a cedarn cover”; and Tennyson, Geraint and Enid, the line,—“And moving toward a cedarn cabinet.” So also William Barnes, in his Rural Poems, uses the expression, “stonen jugs.”
