The New Student's Reference Work/Severn

Severn (sĕv′ẽrn), the second largest river of England, rises in Wales and after 210 miles falls into Bristol Channel. It is navigable for 180 miles; a canal has helped navigation from Gloucester, and is now being extended to Worcester. Below Gloucester the swiftly flowing tide produces a bore or wave five or six feet high. The Severn is a beautiful as well as an important river.
