a river of England, county of York, is formed by the junction of the Swale and the Ure, which unite near Borough Bridge. It flows through the great plain of Yorkshire, at first S.E. as far as the town of York, which it passes, and then pursues an irregular course S. and S.E., until it joins with the Trent to form the estuary of the Humber, by which it discharges its waters into the German Ocean. It receives the Nidd, the Wharfe, and the Don, from the left, and the Derwent from the right. Its whole length is about 60 miles; and it is navigable for large vessels up to York, 45 miles from its mouth.

Great, another river of England, rises near Brackley, Northamptonshire, and flows in a very winding course, dividing for a short distance the counties of Oxford and Buckingham, and flowing in succession through Buckingham, Bedford, Huntingdon, Cambridge, and Norfolk, until it falls into the Wash, after a course of 160 miles, about two-thirds of which is navigable. It is the most meandering of English rivers, and the one that traverses the greatest extent of level country. The towns of Buckingham, Bedford, Huntingdon, and Ely, are on its banks. Its principal tributaries are the Old Nen, Cam, Little Ouse, Stoke, and Nar.

Little, an affluent of the preceding river, rises in Suffolk, and flows N.W. till it joins the Great Ouse on the borders of Cambridge and Norfolk.
