52ra PHILOSOPHICAL TRANSACTIONS. [aNNO 16QS. 



nearer the town than now, where he endeavours to show, that there was for- 

 merly a river of the name of Rother, Romney, and Limene, and that it had its 

 mouth at or by Romney; and when, and upon what occasion it forsook its 

 wonted channel. The first two he proves by old records, where he observes 

 that its mouth was wide enough to receive a fleet of 250 sail of Danish pirates, 

 An. 893, who towed up their vessels 4 miles within the land ; which it has now 

 so forsaken, that there is neither harbour nor channel, which was turned another 

 way by a great inundation of the sea about the year 1287. Next he gives the 

 derivation of Romney, Apledore, Gilford, and Winchelsey. 



As to the forts, he begins with Regulbium, now Reculver, where are still the 

 remains of Roman tiles; here he observes, that all places ending in Chester, 

 arise from the ruins of the old Roman castra, this place being once called 

 Raculf-cester. All the Roman colonies, &c. being upon hills, he believes this 

 might be placed on the ascent where the church now stands, or in the church- 

 yard. 2. The next fort is Rutupium, or Richburough, mentioned before 

 amongst the ports. The ren)ains of the walls of this fort inclose almost as 

 much ground as the Tower of London ; here has been, and still is, more Ro- 

 man coins found, than in any place in England. 3. Dubris or Dover, where 

 he believes the church to have risen out of the old Roman fortress, and the 

 square tower in the middle, fitted with holes for speculation, to have been the 

 very Roman specula or watch-tower, and the Devil's Drop the remains of the 

 Roman pharos. 4. Folkstone, a place famous for Roman antiquities, which he 

 suspects the same with the Lapis Tituli of Ninius. 5. Lim or Limhill, where 

 Stutfall-Castle, with a large circuit of 10 acres, was of old inclosed with a 

 Roman wall ; ruined not so much by time, as a seizure of its materials for 

 building Lim-Church, and the archdeacon's castellated mansion. This place is 

 also called Shipwey. 6. The last Kentish fort is Anderida or Anderidos ; as to 

 the situation, he is less certain whether at Pemsey, Hastings, or Newenden, 

 though he inclines to one of the former. The Weald was formerly called Sylva 

 Andred, a desert place unpeopled, filled only with herds of deer and droves of 

 hogs. He ends this treatise with an enumeration of the quit-rents formerly 

 paid out of the Weald, as gavel-swine, scot-ale, pannage, gate-penny, sumer- 

 hus-silver, corredy, and danger.
