128 THE ESSEX NATURALIST. In one of these re-fits (No. 5) both pieces were found near to- gether in the "Relic-bed," but at different levels, one in the upper and the other in the lower part. Another joins a flake from the bleached sand in area XIX. with another flake found in the "Relic-bed" some ten or twelve feet away. A third joins two pieces of a broken flat quern of sarsen stone, one from the bleached sand, also of XIX. and the other piece from the main body of the same inner bank about 6 or 8 feet away. Now, although the "Relic-bed" is later than the ramparts, I think the evidences that we have been considering indicate that the difference of date is only a trivial detail in the progress of the work. Of course, one cannot know, but the re-fitting of pieces between the inner bank and the "Relic-bed" suggests the idea that the latter may represent the camping ground of the men who were making the banks. If it be objected that these re-fits might have been antiquities pre-existent in the soil, I would answer by reiterating the general evidence that the flakes are in "mint" condition and have never been exposed to the atmosphere, but must have been buried in the soil at the time they were made. There are, however, a few flakes which show patination, and these may be of earlier date than the camp, but they are very few, and their rejection as being untrustworthy as evidence does not affect the character of the flint industry. The Loughton Camp industry does not stand alone as evidence of Iron Age flint working. There is a good deal of scattered evidence of the contemporary association of flint implements with Iron Age remains. I have also, in my own collection, some important evidences that are as yet unpublished, pointing to the same conclusion. After all, it is only what one would expect. Iron working must have been a localized industry, and iron implements expensive in baiter value ; they were probably unobtainable at times. If the conclusions suggested here be sound, then our Loughton Camp collection is certainly one of the best Early La Tene flint industries that is yet available for comparative study. Although not a large one, it is representative of a great variety of types. Many of the flint implements from Loughton Camp are made from flint fresh from the chalk, which must have been brought
