FURTHER REMARKS BY T. V. HOLMES. 69 a few yards above the level of the flat, it cannot be an ordinary farm ditch. To me it is evidence that it is one ; for while nature gives a more or less curved line to boundaries of a geological kind, farmers tend to straight lines in their hedges and ditches. Thus the two seldom coincide for more than a very short distance. On the other hand, a ditch for defensive purposes would naturally have been made to keep to the border of the alluvium, in order to be uniformly full of water, would have been very broad, and would have had an earthen rampart on its inner edge, consisting of material thrown up out of the ditch. My inference from the absence of any mention of this Harlow hill in the "Gentleman's Magazine Library," is simply that the learned editor of that useful series of volumes has not thought its archaeological interest sufficiently well-established. For an antiquary of 1821 was capable de tout in questions of this kind, and ready to jump at any conclusions. Consequently, I should not have thought the matter worth writing about had not an accomplished archae- ologist like Mr. Gould adopted similar views in 1894. I cannot see the slightest evidence that this Harlow hill was ever fortified by earthworks. The surface of the hill presents perfectly natural contours, which have never been modified artificially. The foun- dations of walls were, I think, simply those of farm buildings, as, had they belonged to a fortress, the fosse and other earthworks would have remained when the walls were removed to make others elsewhere, just as in the case of so many ancient castles whose sites are now marked mainly by their earthworks, as at Stansted Mountfitchet. Mr. Gould appears to object to a comparison between this supposed earthwork at Harlow and the unquestionable one at Bishop's Stortford. But, surely, as the two both arise from the alluvial flat of the same river, and are only six miles apart, no test can be fairer or more decisive. And I think that any visitor to them cannot fail to recognise the fact that their differences are not of degree but of kind. And that what the one is the other is not. The question of water supply to the Harlow hill is quite a subordinate one. It is almost certain that a specially good and commanding site would be occupied by an ancient earthwork, even though the water supply might be indifferent or precarious. But the Harlow hill offers no advantages of position and height. As regards its water supply there would, of course, be no difficulty in
