Medway

Medway, a river of England which, rising, partly in Surrey and partly in Sussex, flows N.E., chiefly through Kent, for a distance of 58 miles till it joins the Thames near Sheerness by an estuary 12 miles in length. Tunbridge, Rochester, and Maidstone are upon its banks, and it is navigable for vessels of some size as far as the latter town, whilst boats and barges can ascend to Penshurst.
