48 EPPING FOREST speculations have been to a great extent set at rest by the explorations conducted by the Essex Field Club in 1881 and 1882, under the able guidance of General Pitt-Rivers, and other experi- enced members of the club. Popular tradition attributes the origin of Ambresbury Banks to Queen Boadicea, and places the site of her final overthrow by Suetonius in this neighbourhood; but in the opinion of those best qualified to give one, there is no reliable evidence of this. On the other hand the verdict of General Pitt-Rivers is that this camp is undoubtedly of British origin, but whether erected before or after the Roman Conquest there is no sufficient evidence to show. The data upon which he founds this conclusion are, first, that the configuration of the ramparts is adapted to the features of the ground, instead of being constructed geometrically, which is the distinguishing feature of Roman camps; and secondly, the nature of the fragments of pottery implying a primitive condition of the art, and flint chips which were discovered in digging a section through the rampart and ditch. Those fragments which were discovered under the ram- part itself, and upon the ancient surface-line, are necessarily of the same date as, or older than, the camp itself; and their character indicates a British origin. If the Romans had had any hand in the structure, it is all but certain that some remains indicating a higher civilisation would have been found in this part of the excavation. The height of the rampart appears to have been originally 10 feet, and the ditch of correspond- ing depth. Both height and depth are much diminished by the denudation of ages. Some think it unlikely that a camp would have been constructed in the midst of a wood, and it is inferred that the land must have been open at that time. The Loughton Camp, which is distant about 2 miles south-east of Ambresbury Banks, is a smaller intrenchment containing 11 or 12 acres, but not so well defined ; and is besides covered and partly
