Brook.—This later, or English, name for a small stream appears only as a termination. We have Cranbrook, a reminder, like Cranbourne elsewhere, of the time when cranes were not uncommon in England. These are the places: Brook, a village on a tributary of the Stour; Brookland, near a branch of the Rother; and Brook Street, near Woodchurch. And may not Kidbrooke, or Kedbrook, be “the brook from the Coed”—the Celtic word for a wood? Bourne.—The Anglo-Saxon Burne for stream appears not only in the Bourne and Bourne Park, and the various Nail-bournes, or intermittently flowing brooks, but also in Bekesbourne, Bishopsbourne, Patrixbourne, Littlebourne, the Ravensbourne, Hollingbourne, Brabourne (the broad bourne), Northbourne, and perhaps Sittingbourne, although this is on a creek rather than a brook. Cray.—From the Saxon Cregga, a small brook, a tributary of the Darent or Derwent. In 457 A.D. Hengist and his son Æsc (Ash, or, metaphorically, ship) slew 4,000 Britons at Crecganford, and drove the rest out of Kent to Lundenbyrg (London). So the _Saxon Chronicle_ records. Another old chronicler calls this the battle of the Derwent. The valley of the Cray contains the villages of Crayford, St. Paul’s (probably S. Paulinus’) Cray, St. Mary’s Cray, Foot’s Cray, and the district is commonly called the Crays. Darent.—Like Dover’s Dour, from the Celtic root Dur for water or river, comes the Der-went, of which Darent is a variation. Dwr-gwyn in Welsh is the clear water. There are four Derwents in England, besides Lake Derwent Water. Dartford is the ford of the Darent. Dour.—The living Celtic tongues of Wales, Ireland and Scotland preserve the Celtic Dur—Dwr in Welsh, Dur in Gælic and Erse. There are other Dours in Fife and Aberdeen, and the Dover or Dur-beck in Notts, and in Sussex the Roman itinerary gives Portum Adurni, whence it has been assumed that there was an Adour river. But Prichard gives forty-four ancient names containing this root in Italy, Germany, Gaul, and Britain. Eden.—The Eden, on which is Edenbridge, is a tributary of the Medway. Various rivers of this name are found also in Cumberland, Yorks, Fife and Roxburgh, containing the Celtic root Dan, Don, or Den, for water or river. Lee.—This is a brook rising at Eltham Place, and giving its name to Lee Street and Lee, thence flowing to Lewisham. The more important river Lea on the opposite side of the Thames is called Lygan in the _Saxon Chronicle_. In Essex also there is the Lea-beck, which shows a Celtic name with a suffix attributable to the Danish marauders whose becks are more common in the north of England. The dropping of the last syllable of Lygan would give the Lee. Len.—This short tributary of the Medway has been neglected by writers on place-names; but it might be the Celtic Levn, smooth, as in Loch Leven and three rivers of that name in Scotland, besides others in Gloucestershire, Yorks, Cornwall, Cumberland, and Lancashire.
