The Nuttall Encyclopedia
a lovely winding river in South Wales, which rises near the source of the Severn on Plinlimmon, and falls into its estuary at Chepstow, 125 m. from its head; rapid in its course at first, it becomes gentler as it gathers volume; barges ascend it as far as Hereford, but a high tidal wave makes navigation dangerous at its mouth.
