LEAM (THE), a river of Northampton and Warwick. It rises near the boundary between the counties; runs 2½ miles north-eastward, within Northampton; proceeds 3½ miles northward along the boundary; and goes windingly westward in Warwickshire, past Leamington-Hastings, Marton, Honingham, and Leamington-Priors, to the Avon, in the eastern vicinity of Warwick. Its length of course is about 25 miles; and its chief tributary is the Ichene.
