NOTES ON ANCIENT DEFENSIVE EARTHWORKS. 155 Bures, Milton, Maldon, Pleshey, Shoebury, Chipping Ongar and West Ham. Among the Hertfordshire examples are Stanstead Mountfitchet and Bishop Stortford. A singular feature about this list, which is given in the latest of the papers mentioned (Arch. Journ., Vol. 46. 1889), that styled "A Contribution to a complete list of Moated Mounds or Burhs," is that after mentioning Blethebury, Milton, Maldon, Shoe- bury and West Ham. Mr. Clark adds, "Query, gone," or "Query, mound," there being apparently no evidence that a mound ever existed at the places named. On the other hand the mounds at Stebbing,5 Great Canfield and Rayleigh are not mentioned at all. However, though I think that the earthworks of Pleshey belong to the same class as those of Rayleigh, I would not include either as mere Burhs. Passing over the moundless Burhs mentioned by Mr. Clark, it appears to me that the defensive earthworks of Essex and its borders having mounds are divisible into two classes as distinct as are the Border Castles, such as Alnwick, Warkworth or Bamborough, from mere Border peel towers. In the more important class I would group Clare, Stansted Mountfitchet, Pleshey and Rayleigh ; in the less important, Bishop Stortford, Chipping Ongar, Mount Bures and Stebbing. The latter may well have been the mere fortified centres of Saxon estates, but, as we have seen, the available evidence tends to show that the former are of earlier date and occupied positions of much greater importance. It may probably be urged, ou the other side, that though much of the earthworks at Norwich, Castle Acre, Thetford and other places may have been British, yet that the great mound is a distinctive Saxon feature, and must have been added at a later date. I have already reminded you that even to the prehistoric people who made the gigantic mound at Silbury and the smaller barrows of Salisbury Plain, mound-making was an extremely familiar operation. Also that if the great mound in defensive earthworks is a peculiarly Saxon feature, it is an extraordinary thing that there should exist a popular tradition that the huge mound at Thetford—a town so prominent in the ninth and tenth centuries—was the work of the Devil. For I need hardly point out that such an explanation, wherever it may be met with, implies that the object to which this origin is imputed is not the work of the race thus explaining its existence—which in this case is the Saxon. 5 The Stebbing mound is not mentioned either by Morant or in Murray's Handbook to Eastern Counties. It is simply a moated mound.
